DESCRIPTION:

Technical Field of the Invention

The present invention relates to a method of manufacturing a differentially dyeing charged textile yarn or a pro-fashion yarn for the purposes of weaving or knitting fabrics and garments, which on dyeing gives a heather or melange look.

Background of the Invention

[0002] Textile materials including woven fabrics or knitted fabrics made from spun and filament yarns made of natural cellulose fibers or regenerated cellulose fibers are dyed with a variety of reactive or direct dyes. Typically, the dyeing process is an exhaust method in which the dyeing liquor contains a reactive or direct dye. The dyeing processes are usually accomplished at elevated temperature while using commercially available reactive or direct dyes in the presence of alkali and salt.

[0003] Textiles of different origin, mostly made of cotton are frequently dyed using direct dyes or reactive dyes which are anionic. Textile fibers or fabrics or garments are colored using these dyes in traditional dyeing methods. Since there occurs an electrostatic repulsion between the negatively charged dye molecules and the negative charges generated on textile surface when dipped in water, alkali and salts are used in large amounts to neutralize negative charges and facilitate effective dyeing of the textile fibers or fabrics or garments. The alkali compounds include hydroxides and carbonates of alkali metals like sodium, whereas the salts frequently used for the purpose include chloride and sulphate salts of sodium. These alkali compounds stabilize the covalent bonds formed between the fiber or fabric surface and the dye molecule.

[0004] In many conventional dyeing methods, reactive or direct dyes, salts and the alkali are released into water bodies after the dyeing processes. The un-reacted dyes left in the dyed textiles and surplus alkali used is left as effluents which cause environmental hazards.

[0005] Apart from the above mentioned environmental problems, conventional dyeing methods rise different shortcomings which have commercial impact. The conventionally dyed fabrics sometimes undergo discoloration during washing if the dyes are not attached to the fibers through a sufficiently strong bond. The unbound dyes migrate during the wash. They may go on to other textiles and discolor or stain them and moreover this is a temperature dependent process.

[0006] Other limitations of using traditional dyeing methods for manufacturing fabrics and garments includes the availability of textiles dyed in limited colors and in limited patterns..

[0007] To overcome other limitations of conventional dyeing methods which are familiar in the public domain, the present invention provides a method of manufacturing a textile yarn having different concentrations of positive charge on its surface and to fabricate a variety of differentially dyeable textiles and garments from this yarn.

The step of charging the cellulose fibers with the at least one cationizing agent includes using a quaternary ammonium compound known as 3-chloro 2-hydroxypropyl trimethylammonium chloride. The quaternary ammonium compound more preferably includes a C1-C4 alkyl ammonium halide radical, wherein the C1-C4 alkyl ammonium halide compound has a structural formula, C1CH2CH0HCH2N+ RR1 R2 X" where R, R1 and R2 are alkyl groups, more preferably methyl group and X" is a halide radical.

[0028] According to an exemplary aspect of the present invention, the method for manufacturing a differentially dyeing charged textile yarn or a pro-fashion yarn for making fabrics and garments includes blending the treated cellulose fibers with un-treated cellulose fibers in any pre-determined blend ratio ranging from 1% to 99% through any of the seven blending methods available in the ring spinning technology.

[0029] According to an exemplary aspect of the present invention, the different blending methods for producing differentially dyeing charged textile yarn or pro-fashion yarn are bale mixing, fiber blending, flock blending, lap blending, sheet blending, sliver blending and roving blending. Any of the above blending methods can be followed for producing pro-fashion yarn.

[0030] According to an exemplary aspect of the present invention, the bale mixing method for manufacturing the pro-fashion yarn includes subjecting the bales containing treated and un-treated cellulose fibers randomly through a bale opener or by manual way of opening the fibers and blending the fibers in any pre-determined blending ratio ranging from 1% to 99%. This process is followed by subjecting the cellulose fibers through blow room where the cellulose fibers are beaten, fluffed up and made into a lap form. The resulting lap is then sent to carding. Carding is a mechanical process that breaks up unorganized clumps of fibers and then aligns the individual fibers so that they are more or less parallel with each other. The carded slivers are then sent to combing (optional) and drawing. In combing, the short fibers are removed, whereas in drawing, the fibers are stretched and uniformly aligned. The slivers with uniform fiber alignment are then sent to roving where the slivers are even more thinned. The roving is then sent to spinning where the pro-fashion yarn is spun and wound over a ring cop. The ring cops are finally sent to winding. In winding, the yarn is wound over a cone or cheese, free of defects.

[0031] According to an exemplary aspect of the present invention, the fiber blending method of manufacturing the pro-fashion yarn includes subjecting the treated and un-treated cellulose fibers together by blending them in a pre-determined blending ratio ranging from 1% to 99% in a mixing department. This process is followed by subjecting the blended cellulose fibers through blow room where the cellulose fibers are beaten, fluffed up and made into a lap form. The resulting lap is then sent to carding. Carding is a mechanical process that breaks up unorganized clumps of fibers and then aligns the individual fibers so that they are more or less parallel with each other. The carded slivers are then sent to combing (optional) and drawing. In combing, the short fibers are removed, whereas in drawing, the fibers are stretched and uniformly aligned.

The resulting lap is then sent to carding. Carding is a mechanical process that breaks up unorganized clumps of fibers and then aligns the individual fibers so that they are more or less parallel with each other. The carded slivers are then sent to an optional combing step and then drawing. In combing, the short fibers are removed, whereas in drawing, the fibers are stretched and uniformly aligned. The slivers with uniform fiber alignment are then sent to roving where the slivers are even more thinned. The roving is then sent to spinning where the pro-fashion yarn is spun and wound over a ring cop. The ring cops are finally sent to winding. In winding, the yarn is wound over a cone or cheese, free of defects.

[0033] According to an exemplary aspect of the present invention, the lap blending method of manufacturing the pro-fashion yarn includes subjecting the treated and un-treated cellulose fibers separately through a blow room where the fibers are beaten, fluffed up and made into a lap form. The resulting laps are then sent to carding where two laps containing treated and un-treated fibers are carded together in any predetermined blend ratio ranging from 1% to 99%. Carding is a mechanical process that breaks up unorganized clumps of fibers and then aligns the individual fibers so that they are more or less parallel with each other. The carded slivers containing treated and un-treated fibers are then sent to an optional combing step and drawing. In combing, the short fibers are removed, whereas in drawing, the fibers are stretched and uniformly aligned. The slivers with uniform fiber alignment are then sent to roving where the slivers are even more thinned. The roving is then sent to spinning where the pro-fashion yarn is spun and wound over a ring cop. The ring cops are finally sent to winding. In winding, the yarn is wound over a cone or cheese, free of defects.

[0034] According to an exemplary aspect of the present invention, the sheet blending method of manufacturing the pro-fashion yarn includes subjecting the treated and un-treated cellulose fibers separately through blow room where the fibers are beaten, fluffed up and made into a lap form. The resulting laps are then sent to carding where two laps containing treated and un-treated fibers are carded. The treated and un-treated slivers can be blended in any predetermined blend ratio ranging from 1% to 99% in either sliver lap or ribbon lap or in combing. The carded slivers containing treated and un-treated fibers are subjected in sliver lap, where the carded slivers are converted into a sheet form which is then followed by ribbon lap. Here the fibers are even more aligned in the sheet form. The sheets of fiber are then sent for combing, where the short fibers are removed. The slivers from combing are then passed on to the drawing process. In drawing, the fibers are stretched through a series of drafting rollers in a draw frame and are then uniformly aligned. The slivers with uniform fiber alignment are then sent to roving where the slivers are even more thinned. The roving is then sent to spinning where the pro-fashion yarn is spun and wound over a ring cop. The ring cops are finally sent to winding. In winding, the yarn is wound over a cone or cheese, free of defects.

[0035] According to an exemplary aspect of the present invention, the sliver blending method of manufacturing the pro-fashion yarn includes subjecting the treated and un-treated cellulose fibers separately through blow room where the fibers are beaten, fluffed up and made into a lap form. The resulting laps are then sent to carding where two laps containing treated and un-treated fibers are carded. The treated and un-treated slivers are blended together in any pre-determined blend ratio ranging from 1% to 99% in a draw frame.

manufacturing of pro-fashion yarn through roving blending method in which flow diagram 1300 depicts natural cellulose fibers and flow diagram 1400 depicts regenerated cellulose fibers.

[0043] According to an exemplary aspect of the present invention, the cellulose fiber material preferably includes but not limited to a natural cellulose fiber material, a regenerated cellulose fiber material or a combination of both natural and regenerated cellulose fiber material. The natural cellulose fiber material preferably includes cotton, linen and the like. The regenerated cellulose fiber material includes viscose, rayon, modal and the like.

[0044] Referring to FIG.l is a flow diagram 100 illustrating a method of manufacturing the differentially dyeing charged textile yarn or a pro-fashion yarn from natural cellulose fibers through bale mixing method. In accordance with an exemplary embodiment of the present invention, the method of manufacturing the differentially dyeing charged textile yarn starts at step 102 which illustrates subjecting the natural cellulose fiber material to any mechanical means for removing the impurities or contaminants. The natural cellulose fiber here includes one of cotton or linen in any form.

[0045] From step 102, the flow diagram 100 continues with step 104 where the resulting natural cellulose fibers are obtained in any form through any mechanical means. After the natural cellulose fibers are passed through any mechanical means such as blow room or carding or combing or drawing, the resulting natural cellulose fibers can be in any form such as in the form of fleece or flock or slivers etc.

[0046] From step 104, the flow diagram 100 continues with step 106 where the resulting natural cellulose fibers are subjected to surface charging or cationization process. The natural cellulose fibers are surface charged with a predetermined cationizing agent to obtain a plurality of positively charged fibers of any pre-determined concentration ranging from 1% to 100%. The step of charging the natural cellulose fibers with the cationizing agent includes using a quaternary ammonium compound known as 3-chloro 2-hydroxypropyl trimethylarnmonium chloride. The quaternary ammonium compound more preferably includes a C1-C4 alkyl ammonium halide radical, wherein the C1-C4 alkyl ammonium halide compound has a structural formula, ClCH2CHOHCH2N+ RR1 R2 X" where R, R1 and R2 are alkyl groups, more preferably methyl group and X" is a halide radical.

[0047] From step 106, the flow diagram 100 continues with step 108 where the resulting positively charged natural cellulose fibers are blended with un-treated natural cellulose fibers in a pre-determined blend ratio ranging from 1% to 99% in bale form. Here, either the treated fibers can be in bale form or the cleaned, un-treated fibers can be in bale form. So, mixing or blending of the treated natural cellulose fibers along with un-treated natural cellulose fibers in bale form can be vice versa. Blending can be done by using any mechanical device such as mixing bale opener or by manual way for mixing or blending the fibers.

[0048] From step 108, the flow diagram 100 continues with step 110 where the blended natural cellulose fibers containing treated and un-treated fibers are subjected through blow room to obtain the plurality of blended natural cellulose fibers in a lap form. The natural cellulose fiber material is beaten and fluffed up in blow room to clear scrap and contaminants such as seeds, weeds, leaf bits and the like and then processed and pressed
into a lap form which is sent to carding.

[0049] From step 110, the flow diagram 100 continues with step 112 where the plurality of blended natural cellulose fibers from blow room is obtained in a form of slivers by carding the lap in a carding machine. Carding is a mechanical process that breaks up unorganized clumps of fibers and then aligns the individual fibers so that they are more or less parallel with each other.

[0050] From step 112, the flow diagram 100 continues with step 114 which illustrates an optional step of combing or drawing of the carded slivers with un-even fiber alignment to obtain slivers of uniform fiber alignment in a draw frame. Combing is the process of removal of short fibers present in the slivers after carding. Combing is optional as it removes only the short fibers and prevents hairiness of the yarn. The natural cellulose fibers after carding or combing needs to be stretched or thinned and the fibers should be parallelly aligned to each other. This uniform alignment of natural cellulose fibers is done in the drawing process where the slivers are stretched and fibers are uniformly aligned by passing the slivers through a series of drafting rollers.

[0051] From step 114, the flow diagram 100 continues with step 116 where the slivers are even thinned or drafted to a fine roving which is sent for ring spinning. The drafted slivers of uniform fiber alignment are even more drafted to a thin form called roving. Roving is wound on bobbins which are then taken to spinning. Roving can be done only if the pro-fashion yarn is being spun using ring-spun technology where the yarn is wound over a ring cop. In spinning, the roving is finally drafted through a series of drafting rollers where the fibers are twisted and finally wound as a pro-fashion yarn over a ring cop.

[0052] From step 116, the flow diagram 100 continues with step 118 where the pro-fashion yarn of any pre-determined count is wound over cone or cheese free of defects. Once the ring cops arrive from spinning, they are taken to winding where the pro-fashion yarn is wound over a cone or cheese in case of a ring spinning. The defective parts of the pro-fashion yarn such as slubs, thick and thin place, neps and the likes are electronically or mechanically sensed and are cleared. A defect free, cationized or surface charged cellulose yarn, also known as a pro-fashion yarn is finally obtained.

[0053] From step 118, the flow diagram 100 ends with step 120 where the pro-fashion yarn free from defects is finally obtained.

[0054] Referring to FIG.2 is a flow diagram 200 in accordance with an exemplary aspect, illustrates a method of manufacturing the differentially dyeing charged textile yarn or a pro-fashion yarn from regenerated cellulose fiber through bale mixing method. The method of manufacturing differentially dyeing charged textile yarn starts at step 200.

[0055] From step 200, the flow diagram 200 continues with step 202 which illustrates subjecting the regenerated cellulose fiber material towards surface charging or cationization process. The regenerated cellulose fibers are surface charged with a cationizing agent to obtain a plurality of positively charged fibers of any pre-determined concentration ranging from 1% to 100%. The step of charging the regenerated cellulose fibers with the cationizing agent includes using a quaternary ammonium compound known as 3-chloro 2-hydroxypropyl trimethylammonium chloride. The quaternary ammonium compound more preferably includes a C1-C4 alkyl ammonium halide radical, wherein the C1-C4 alkyl ammonium halide compound has a structural formula, C1CH2CHOHCH2N* RR1 R2 X" where R, R1 and R2 are alkyl groups, more preferably methyl group and X" is a halide radical. The regenerated cellulose fibers here include one of a viscose, rayon, modal and the like.

[0056] From step 202, the flow diagram 200 continues with step 204 where the resulting positively charged regenerated cellulose fibers are blended with un-treated regenerated cellulose fibers in any pre-determined blend ratio ranging from 1% to 99%, in a bale form. Here, either the treated regenerated cellulose fibers or the un-treated fibers can be in bale form. So, mixing or blending of the treated regenerated cellulose fibers along with un-treated regenerated cellulose fibers in bale form can be vice versa. Blending can be done by using any mechanical device such as bale opener or by manual way for mixing or blending the fibers.

[0057] From step 204, the flow diagram 200 continues with step 206 where the blended regenerated cellulose fibers containing treated and un-treated fibers in a pre-determined blend ratio are subjected through blow room to obtain the plurality of treated fibers in a lap form. The regenerated cellulose fiber material is beaten and fluffed up in blow room and then processed and pressed into a lap form which is sent to carding.

[0058] From step 206, the flow diagram 200 continues with step 208 where the plurality of blended regenerated cellulose fibers from blow room is obtained in a form of slivers by carding the lap in a carding machine.

[0059] From step 208, the flow diagram 200 continues with step 210 which illustrates drawing of the carded slivers with un-even fiber alignment to obtain slivers of uniform fiber alignment in a draw frame. The regenerated cellulose fibers after carding needs to be stretched or thinned and the fibers should be parallelly aligned to each other. This uniform alignment of natural cellulose fibers is done in the drawing process where the slivers are stretched and fibers are uniformly aligned by passing the slivers through a series of drafting rollers.

[0060] From step 210 the flow diagram 200 continues with step 212 where the slivers are even thinned or drafted to a fine roving, which is sent for ring spinning. The drafted slivers of uniform fiber alignment are even more drafted to a thin form called Roving. Roving is wound on bobbins which are then taken to spinning. Roving can be done only if the pro-fashion yarn is being spun using ring-spun technology where the yarn is wound over a ring cop. In spinning, the roving is finally drafted through a series of drafting rollers, where the fibers are twisted and finally wound as a pro-fashion yarn over a ring cop.

[0061] From step 212, the flow diagram 200 continues with step 214 where the pro-fashion yarn of any pre-determined count is wound over cone or cheese free of defects. Once the ring cops arrive from spinning, they are taken to winding where the pro-fashion yarn is wound over a cone or cheese, in case of a ring spinning. The defective parts of the pro-fashion yarn such as slubs, thick and thin place, neps and the likes are electronically or mechanically sensed and are cleared. A defect free, cationized or surface charged cellulose yarn, also known as a pro-fashion yarn is finally obtained.

[0063] Referring to FIG.3, is a flow diagram 300 illustrating a method of manufacturing the differentially dyeing charged textile yarn or a pro-fashion yarn from natural cellulose fibers through fiber mixing method. In accordance with an exemplary embodiment of the present invention, the method of manufacturing the differentially dyeing charged textile yarn starts at step 302 which illustrates subjecting the natural cellulose fiber material through any mechanical means for removing the impurities or contaminants. The natural cellulose fiber here includes either cotton or linen in any form.

[0064] From step 302, the flow diagram 300 continues with step 304 where the resulting natural cellulose fibers are obtained in any form through any mechanical means. After the natural cellulose fibers are passed through any mechanical means such as blow room or carding or combing or drawing, the resulting natural cellulose fibers can be in any form such as in the form of fleece or flock or slivers etc.

[0065] From step 304, the flow diagram 300 continues with step 306 where the resulting natural cellulose fibers are subjected towards surface charging or cationization process. The natural cellulose fibers are surface charged with a cationizing agent to obtain a plurality of positively charged fibers of any pre-determined concentration ranging from 1% to 100%. The step of charging the natural cellulose fibers with the cationizing agent includes using a quaternary ammonium compound known as 3-chloro 2-hydroxypropyl trimethylammonium chloride. The quaternary ammonium compound more preferably includes a C1-C4 alkyl ammonium halide radical, wherein the C1-C4 alkyl ammonium halide compound has a structural formula, ClCH2CHOHCH2N+ RR1 R2 X" where R, R1 and R2 are alkyl groups, more preferably methyl group and X" is a halide radical.

The natural cellulose fibers after carding or combing needs to be stretched or thinned and the fibers should be parallelly aligned to each other. This uniform alignment of natural cellulose fibers is done in the drawing process where the slivers are stretched and fibers are uniformly aligned by passing the slivers through a series of drafting rollers.

[0070] From step 314, the flow diagram 300 continues with step 316 where the slivers are even thinned or drafted to a fine roving, which is sent for ring spinning. The drafted slivers of uniform fiber alignment are even more drafted to a thin form called roving. Roving is wound on bobbins, which are then taken to spinning. Roving can be done only if the pro-fashion yarn is being spun using ring-spun technology where the yarn is wound over a ring cop. In spinning, the roving is finally drafted through a series of drafting rollers, where the fibers are twisted and finally wound as a pro-fashion yarn over a ring cop.

[0121] From step 906, the flow diagram 900 continues with step 908 where the treated and un-treated fibers are subjected separately through blow room to obtain the plurality of treated and un-treated fibers separately in a lap form. The natural cellulose fiber material is beaten and fluffed up to clear scrap and contaminants such as seeds, weeds, leaf bits and the like in the blow room and then processed and pressed into separate laps which is sent to carding.

[0122] From step 908, the flow diagram 900 continues with step 910 where two different laps containing treated and un-treated fibers are passed through carding separately to obtain plurality of treated and un-treated fibers separately in a sliver form of un-even fiber alignment.

The regenerated cellulose fibers are surface charged with a cationizing agent to obtain a plurality of positively charged fibers of any pre-determined concentration ranging from 1% to 100%. The step of charging the regenerated cellulose fibers with the cationizing agent includes using a quaternary ammonium compound known as 3-chloro 2-hydroxypropyl trimethylammonium chloride. The quaternary ammonium compound more preferably includes a C1-C4 alkyl ammonium halide radical, wherein the C1-C4 alkyl ammonium halide compound has a structural formula, C1CH2CH0HCH2N+ RR1 R2 X" where R, R1 and R2 are alkyl groups, more preferably methyl group and X" is a halide radical. The regenerated cellulose fibers here include one of a viscose, rayon, modal and the likes.

[0132] From step 1002, the flow diagram 1000 continues with step 1004 where the resulting positively charged regenerated cellulose fibers and un-treated regenerated cellulose fibers are subjected separately through blow room to obtain different laps with plurality of fibers in a lap form. Here the fibers are beaten and fluffed up and converted into a lap form which is sent to carding.

[0133] From step 1004, the flow diagram 1000 continues with step 1006 where the plurality of treated and un-treated regenerated cellulose fibers from blow room is carded separately in a carding machine to obtain slivers of un-even fiber alignment.

[0134] From step 1006, the flow diagram 1000 continues with step 1008 where the carded slivers containing the positively charged fibers are passed through the sliver lap machine to obtain a sliver lap containing plurality of treated fibers in a sheet form which is then sent to ribbon lap machine for a better blending and better fiber alignment. In a sliver lap machine, the carded slivers are drawn in together in a row of pre-determined numbers, where the slivers are stretched a little and then wrapped around a spool in a sheet form.

[0135] From step 1008, the flow diagram 1000 continues with step 1010 where the carded slivers containing the un-treated fibers are passed through the sliver lap machine to obtain a sliver lap containing plurality of treated fibers in a sheet form which is then sent to ribbon lap machine for better blending and better fiber alignment. In a sliver lap machine, the carded slivers are drawn in together in a row of pre-determined numbers, where the slivers are stretched a little and then wrapped around a spool in a sheet form.

[0136] From step 1010, the flow diagram 1000 continues with step 1012 where the sliver laps of treated and un-treated fibers are passed together through ribbon lap machine in any pre determined blend ratio ranging from 1% to 99%. The sheets of fiber are even more aligned, drafted and the treated and un-treated fibers are blended evenly. Now the ribbon lap is ready for the combing process.

[0137] From step 1012, the flow diagram 1000 continues with step 1014 where the combing process is done. Combing is the process of removal of short fibers present in the ribbon lap after carding. Combing is done, since it removes the short fibers and prevents hairiness and increases lusture of the yarn. After the removal of short fibers, the sheets of fibers are transformed into slivers which are then passed on to the drawing process. The regenerated cellulose fibers after combing needs to be stretched or thinned and should be parallelly aligned to each other. This uniform alignment of natural cellulose fibers is done in the drawing process where the carded or combed slivers are stretched using a series of drafting rollers where the fibers are uniformly aligned.

[0138] From step 1014, the flow diagram 1000 continues with step 1016 where the slivers are even thinned or drafted to a fine roving, which is sent for ring spinning. The drafted slivers of uniform fiber alignment are even more drafted to a thin form called roving. Roving is wound on bobbins, which are then taken to spinning. Roving can be done only if the pro-fashion yarn is being spun using ring-spun technology where the yarn is wound over a ring cop. In spinning, the roving is finally drafted through a series of drafting rollers, where the fibers are twisted and finally wound as a pro-fashion yarn over a ring cop.

[0139] From step 1016 the flow diagram 1000 continues with step 1018 where the pro-fashion yarn of any pre-determined count is wound over cone or cheese free of defects. Once the ring cops arrive from spinning, they are taken to winding where the pro-fashion yarn is wound over a cone or cheese, in case of a ring spinning. The defective parts of the pro-fashion yarn such as slubs, thick and thin place, neps and the likes are electronically or mechanically sensed and are cleared. A defect free, cationized or surface charged cellulose yarn, also known as a pro-fashion yarn is finally obtained.

[0140] From step 1018, the flow diagram 1000 ends with step 1020 where the pro-fashion yarn free from defects is finally obtained.

[0141] Referring to FIG.l 1 is a flow diagram 1100 illustrating a method of manufacturing the differentially dyeing charged textile yarn or a pro-fashion yarn from natural cellulose fibers through sliver blending method. In accordance with an exemplary embodiment of the present invention, the method of manufacturing the differentially dyeing charged textile yarn starts at step 1102 which illustrates subjecting the natural cellulose fiber material through any mechanical means. Here, the natural cellulose fibers are beaten and fluffed up by removing the impurities present in it. The natural cellulose fiber here includes atleast one of cotton, linen, and the likes in any form.

[0142] From step 1102, the flow diagram 1100 continues with step 1104 where, the resulting natural cellulose fibers are obtained of any form through any mechanical means. After the natural cellulose fibers are passed through any mechanical means such as blow room or carding or combing or drawing, the resulting natural cellulose fibers can be of any form such as in the form of fleece or flock or slivers etc.

[0143] From step 1104, the flow diagram 1100 continues with step 1106 where the resulting natural cellulose fibers are subjected towards surface charging or cationization process.

[0144] From step 1106, the flow diagram 1100 continues with step 1108 where the treated and un-treated fibers are subjected separately through blow room to obtain the plurality of treated and un-treated fibers separately in a lap form. The natural cellulose fiber material is beaten and fluffed up to clear scrap and contaminants such as seeds, weeds, leaf bits and the like in the blow room and then processed and pressed into separate laps which is sent to carding.

[0145] From step 1108, the flow diagram 1100 continues with step 1110 where two different laps containing treated and un-treated fibers are passed through carding separately to obtain plurality of treated and un-treated fibers separately in a sliver form of un-even fiber alignment.

[0146] From step 1110, the flow diagram 1100 continues with step 1112 where the slivers of treated and un-treated natural cellulose fibers are blended together on a draw frame by passing them together in a draw frame in a pre-determined blend ratio ranging from 1% to 99%. The natural cellulose fibers after carding needs to be stretched or thinned and should be parallelly aligned to each other. This uniform alignment of natural cellulose fibers is done in the drawing process where the carded or combed slivers are stretched using a series of drafting rollers where the fibers are uniformly aligned.

[0147] From step 1112, the flow diagram 1100 continues with step 1114 where the slivers are even thinned or drafted to a fine roving, which is sent for ring spinning. The drafted slivers of uniform fiber alignment are even more drafted to a thin form called roving. Roving is wound on bobbins, which are then taken to spinning. Roving can be done only if the pro-fashion yarn is being spun using ring-spun technology where the yarn is wound over a ring cop. In spinning, the roving is finally drafted through a series of drafting rollers, where the fibers are twisted and finally wound as a pro-fashion yarn over a ring cop.

[0148] From step 1114, the flow diagram 1100 continues with step 1116 where the pro-fashion yarn of any pre-determined count is wound over cone or cheese free of defects. Once the ring cops arrive from spinning, they are taken to winding where the pro-fashion yarn is wound over a cone or cheese, in case of a ring spinning. The defective parts of the pro-fashion yarn such as slubs, thick and thin place, neps and the likes are electronically or mechanically sensed and are cleared. A defect free, cationized or surface charged cellulose yarn, also known as a pro-fashion yarn is finally obtained.

[0149] From step 1116, the flow diagram 1100 ends with step 1118 where the pro-fashion yarn free from defects is finally obtained.
