It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Because of the growing importance and popularity of concepts such as green, eco-friendly, and sustainability, natural fibres appear to have become an obvious choice among textile makers and consumers. Synthetic fibres are more easily obtained at a low cost and in a broad variety than natural fibres, but there are numerous challenges to synthetic fibre manufacturing and use that cannot be ruled out. Synthetic fibres take more than 500 years to degrade, making this one of the most significant environmental hazards. When natural fibres are compared to synthetic fibres in this context, natural fibres are biodegradable and long-lasting. Eco-friendly procedures are used at every stage of their manufacturing and disposal. Because of issues such as rising costs of petroleum-based fibres and their environmental impact, natural fibres have found a position in the global textile market. Because of the expanding population and increased demand for textiles, there is a greater possibility of greater environmental effect due to synthetic textile fiber. Many developed nations have been searching for a natural biodegradable alternative to synthetics to address these challenges, with a wide range of applications in the textile sector.
[0004] Hemp is one of the most recent commercial fabrics that is completely sustainable. Hemp is a bast fibre made from the stem of the stinging Hemp plant, which grows wild in temperate regions of the world. Hemp has a variety of physical and chemical qualities, making it one of the greatest commercial textiles. Hemp's physical features, such as fibre length, strength, and being one of the longest natural fibres, contribute to the fabric's longevity. It also has a strong aversion to the elements, mould, sea water, and sunshine. Hemp, once dyed, can provide a wide range of fabrics at a low cost.
[0005] Even though, several dyes and dyeing methods have significantly contributed in providing effective colours to the fabrics, several drawbacks are still associated, such as, expensiveness, deterioration of quality of fabrics, etc. results in a low acceptance condition among common users.

It is strong that product of the present invention not only has the dim sense of colour-spun yarns, stereoscopic sensation, the feature that color is implicit, natural, have levels, and there is the style that colour-changeable yarn color is changeable, randomness is strong, the present invention simultaneously adopts fiber to carry out modification, dyeing, a large amount of water resources can be saved, being combined by ionic linkage between dyestuff and fiber, washing fastness and color fastness are all fine, are fiber dyed yarn and the fabric of a kind of brand-new style.
[0008] The WO2019168407A1 (By- Martin Thorkildsen, Jonny Kristiansen) relates to a core spun yarn where a spun core is covered with natural dyed fibres. The yarn of the invention is a core spun coloured yarn, wherein the manufacturing of the yarn has a low environmental impact. Further, the invention provides a method for producing a core spun yarn coloured with natural dyes. The invention further concerns use of the core spun yarn in manufacturing of fabrics, and provides a fabric comprising the core spun yarn of the invention.
[0009] However, aforementioned solutions are associated with several limitations such as costly, hampering quality of fabrics, etc. Thus, there remains a need in technical advancement in a domain of dyeing of fabrics.

The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention.
[00033] The present invention relates to a field of textile production. More particularly, the present invention relates to method and system to dye the hemp yarns.
[00034] Fig. 1 illustrates an exemplary architecture of system 100 to dye the hemp yarns. The system 100 can comprise a hemp storage 102, a reaction chamber 104, a water chamber 106, a dyeing chamber 108 and other known components of a yarn dyeing device/apparatus. It can be appreciated that the aforementioned components of system 100 are coupled with each other.
[00035] In an embodiment, the hemp storage 102 can be arranged to receive the hemp yarns from a user, wherein the hemp yarns can be available either in an individual form or can be mixed with other yarns, thereby forming mixed yarns like Hemp and Jute, Hemp and Banana, Hemp and Nettle, Nettle and Grey Sheep Wool, Hemp and Black Sheep Wool, Hemp and Grey Sheep Wool, etc. An amount of hemp yarns received at the hemp storage 102 can be in a range of 500 gram to 800 gram. In a scenario, the amount of hemp yarns received at the hemp storage 102 can be in a range of 500 gram to 600 gram. In another scenario, the amount of hemp yarns received at the hemp storage 102 can be in a range of 600 gram to 700 gram. In a more preferred scenario, the amount of hemp yarns received at the hemp storage 102 can be in a range of 700 gram to 800 gram. In an aspect, if the amount of hemp yarns received at the hemp storage 102 is lesser than 500 grams, there might be wastage of a mordant substance and the dye, as such a smaller amount of hemp yarns may not be utilized in production of a fabric of useful size. In an aspect, if the amount of hemp yarns received at the hemp storage 102 is greater than 800 grams, larger content of the mordant substance and the dye might be required, which in turn may require a larger apparatus.
[00036] In an embodiment, the reaction chamber 104 can be arranged to receive the hemp yarns from the hemp storage 102 via a pickup means (Not shown in FIG. 1), which can pick up the hemp yarns from the hemp storage 102 and can transfer the picked hemp yarns in the reaction chamber 104. The reaction chamber 104 may receive a white soil suspension which can bleach the received hemp yarns to obtain the bleached hemp yarn that may be possessed an improved whiteness and softness. The bleaching of received hemp fibres can be done by immersion of the received hemp yarns in a white soil suspension or any other known bleaching solution (e.g., mild hypochlorite solution) for duration of 40 minutes to 80 minutes. In a scenario, the received hemp yarns can be immersed in white soil suspension for duration of 40 minutes to 60 minutes. In another scenario, the received hemp yarns can be immersed in a white soil suspension for a duration of 60 minutes to 80 minutes. In an aspect, if the received hemp yarns are immersed in a white soil suspension for a duration lesser that 40 minutes may not result proper whitening and softening of hemp yarns. In another aspect, if the received hemp yarns are immersed in a white soil suspension for a duration greater that 80 minutes may result in degradation of quality of hemp yarns. It would be appreciated that treatment time of hemp fiber with the suspension of white soil may be dependent on various parameters of hemp (e.g., length of hemp fiber, quantity of hemp fiber, biological source of hemp fiber etc.), parameters of white soil suspension (e.g., concentration, ingredient, particle size etc.) and processing parameters (e.g., temperature, stirring condition etc.). The suspension of white soil may comprise Kamer mitti (i.e., white soil) in arrange of 8-20 gm/l, 12-15 gm/l, 8-10 gm/l, 9.5-10.5 gm/t, 10 gm/l, 11 gm/l or any other suitable concentration. The suspension of the white soil may be effective to remove/fade natural colour of fiber, stain form milky sap, dirt or any other foreign material.
[00037] After treatment with the suspension, the bleached hemp yarns undergo several washing steps, to remove unreacted white-soil from the yarn. Washing can be continued till pH of the yarn and/or washing water reached approximate 7. The washed hemp yarn can be transferred into the reaction chamber, either manually or using appropriate machine such as conveyor belt, robotic arm etc.
[00038] The reaction chamber 104 may receive the mordant substance in an adequate amount (based on the suspension of white soil and water available within the reaction chamber 104) that can be arranged to alter an adhesion property of the bleached hemp yarns (produce after washing) to obtain the mordant treated hemp yarns, wherein the mordant substance can be a dye fixative substance which can be used to set (i.e., bind) dyes on hemp yarns by forming a coordination complex with the dye, which then attaches to the hemp yarns. It may be used for dyeing fabrics or for intensifying stains in cell or tissue preparations.
[00039] Various kinds of mordant substance can be used to modify surface property of the bleached yarn. The mordant substance can be selected from Alum and Ferrous sulphate, wherein alum may give little bit lighter shade to the hemp yarn and on the other hand, the ferrous sulphate may give a little bit darker shade to the hemp yarn. Whereas, both the mordant substances can be adequately absorbed within the hemp yarn. It would be appreciated that effect of mordant action to the bleached yarn can be improvised by modifying treatment condition (e.g., temperature, pressure, time duration, stirring using mechanical blade or manganic stirring etc,).
[00040] The Alum based mordant may comprising Kamer mitti, various excipients (e.g., solubilizer, flavouring agnet etc.) and alum (Aluminum Potasium Sulphate/ Fitkari) – 5-20 gm/lit, 8-12 gm/lit, 10-15 gm/lit, 9.5-10.5 gm/lit, 10 gm/lit, 11 gm/lit, 10.5 gm/lit and 12.5-25 gm/lit. gm per ltr.
[00041] Similarly, the Ferrus sulfate based mordant may comprising Kamer mitti (in appropriate quantity) and Ferrus Sulphate/ Harakasis) in range from: 0.15 - 1.25 gm/lit, 0.5-0.8gm/lit, 0.25-.35 gm/lit, 0.18 gm/lit, 0.2 gm/lit, 0.25 gm/lit, 0.28gm/lit, 0.3 gm/lit, 1-1.5gm/lit, 0.75-0.95gm/lit, 1-1.1 gm/lit and 0.4-0.75gm/lit.
[00042] The mordant treated hemp fiber from reaction chamber 104 can be transferred to water chamber 106, which can be arranged to receive a stream of water from an external water source. The water stream can perform washing of the acquired/received mordant to enable removal of an alkanet or unreacted mordent to produce the alkanet less hemp yarns. The received stream of water may also remove excess of mordant substance from the hemp yarns. The alkanet less hemp yarns can now be available for dyeing within the dyeing chamber 108.
[00043] In an embodiment, the dyeing chamber 108 can be arranged to receive the alkanet less hemp yarns (from water chamber 106) and a solution of natural dye. It would be appreciated that a person ordinarily skill in art can optimize ratio and/or concentration of solution of natural dye with respect to amount of alkanet less hemp yarns. The received mordant treated hemp yarns can be dipped in the natural dye for a duration that ranges from 40 minutes to 80 minutes at a suitable temperature (e.g., room temperature, 60-70 °C) for dyeing the hemp yarns. In a scenario, the received mordant treated hemp yarns can be dipped in the natural dye for a duration that ranges from 40 minutes to 60 minutes at the room temperature for dyeing the hemp yarns. In another scenario, the received mordant treated hemp yarns can be dipped in the natural dye for a duration that ranges from 60 minutes to 80 minutes at the room temperature for dyeing the hemp yarns. In an aspect, if the received mordant treated hemp yarns is dipped in the natural dye for a duration lesser than 40 minutes, the hemp yarns may not properly attain a colour of the dye. In another aspect, if the received mordant treated hemp yarns is dipped in the natural dye for a duration greater than 80 minutes, the hemp yarns may lose their strength that may result in weakening of hemp yarns.
[00044] In an embodiment, the natural dye can be selected from Harshringar flower, Walnut skin, Onion skin, Indigo and Dolu tree root, wherein the natural dye utilizing Harshringar flower may provide darker tone olive green colour to the hemp yarns. The natural dye utilizing walnut skin may provide a lighter tone darker coffee brown colour or little bit blackish tone colour to the hemp yarn. The natural dye utilizing onion skin may provide a tan brown shade to hemp yarns. The natural dye utilizing indigo may provide a bright or a dark bluish tone colour to the hemp yarns. The natural dye utilizing Dolu tree root may provide chocolate brown colour to the hemp yarns.
[00045] In an embodiment, the dyeing chamber 108 comprises a heat source for heating the contents of the dyeing chamber 108, wherein the heat source can be selected from a heat pump, radiant heater, electric furnace, gas burner, cock oven etc. The hemp yarns and the solution of natural dye can be heated at an adequate temperature via the heat source for proper attainment of colour of natural dye over the hemp yarns.
[00046] In an embodiment, the natural dye can be mixed with water and boiled within the dyeing chamber 108 through the heat source at a boiling temperature that ranges from 140° to 160 °F so that the hemp yarns may properly attain the colour of natural dye. In a scenario, the boiling temperature ranges from 140 ° to 150 °F. In another scenario, the boiling temperature ranges 150° to 160 °F. In an aspect, if the boiling temperature is lesser than 140 °F, the received hemp yarns (dipped within the dyeing chamber 108) may not properly attain the colour of natural dye. In another aspect, if the boiling temperature is greater than 180° Fahrenheit, the received hemp yarns (dipped within the dyeing chamber 108) may lose their physical properties.
[00047] In an embodiment, the reaction chamber 104 may comprise a stirring element which can be coupled with a motor, wherein the stirring element may constantly stir the received solution of white soil, mordant substance, hemp yarns and water for providing a uniform mixing.
[00048] In an embodiment, the user activates the motor that may control the stirring element for mixing the mordant substance with the bleached hemp yarns so that mordant substance may evenly distribute, which may result in uniform mixing. The motor’s polarity can be altered for moving the stirring element in dual directions. The motor can be selected from a DC motor, a stepper motor or any other known motor.
[00049] The natural dye can be prepared by dipping/soaking the natural colouring material (e.g., Onion skin, Walnut skin, Harshringar flower etc.) in water for 20-40 hours, followed by removal of the colouring material (through filtration, centrifugation etc.) to produce aliquot comprising natural colouring pigment (which were excreted from colouring material). The aliquot may be concentrated (though heating or freeze drying) to produce concentrated solution of the natural pigment. The concentrated solution may be used for dyeing of hemp fibre. To improve dyeing efficiency of the natural colouring material, water can be heated before the removal of the colouring material.
[00050] The following table illustrates exemplary composition of natural dye can be used to treat the hemp fiber:
Dye Name Composition (For each gram of fiber)
Harshringar flower dye Harshringar Flower (fresh or dry) - 1.5-2.9 gm/lit

Onion skin dye Dry Onion skin - 12-30 gm/lit
Walnut skin dye Walnut skin 28-45 gm/lit
Dolu tree root dye Dolu tree root 35 -55 gm/lit
Indigo dye Indigo 0.35-1.25 gm/lit, Thiorea Dioxide – 0.40-0.75 gm/lit and Soda Ash- 0.20-0.80 gm/lit

[00051] It would be noted that dye composition, mordent composition and bleaching composition may comprise additional ingredients selected from bulking agent, stabilizer, flavouring agent, gelling agent, solubility enhancer, wetting agent, binders, co solvents, preservatives, emulsifying agents, suspending agents and any other excipients are known in dyeing industry.
