Field of the invention:
[0001] The present disclosure generally relates to the technical field of methods for manufacturing ropes, and in specific relates to a method for production of thin aromatic ropes/fibers from aromatic crops using multiple fibers with smooth texture and consistent thickness within less time.
Background of the invention:
[0002] In general, ropes are formed by twisting two or more yarns of the same thickness in the same direction separately to form strands, and then twisting the strands together in the opposite direction to make ropes. The twisting technique usually necessitates at least two people standing at opposite ends of the rope. One person twists the strands by first firmly connecting each piece of chord and then spinning it around. The second person is in charge of twisting the strands together in the other direction to combine them. The process of manufacturing rope takes a long time and is physically demanding, resulting in low production.

[0003] At present, rope-making machines are used to make ropes which are widely used in industrial and domestic applications. The ropes can be electrically conductive or can be non-conductive such as cotton and nylon ropes etc. There are various conventional rope-making machines that are available in the market. It a common practice to twist some stands in one direction, and the other strands in the opposite direction to form the rope as they are laid.

[0004] When making ropes from raw natural fibres, the fibres are usually greased with natural oils first. They're then passed through a succession of machines that clean the fibres, straighten them, spread them apart, and comb them using steel-toothed combs. As the fibres progress through the process, the teeth on each pair of combs become closer together. Carding is a technique of creating a loose, continuous ribbon of fibres known as a web or a sliver. The fibers in the sliver are aligned along the long axis of the ribbon. Synthetic fibers follow a similar process, and tend to align more easily. If the rope is to be made from long filaments of synthetic material, several filaments are grouped together in a process called doubling or throwing. This produces a sliver of multiple plies of filaments.

[0005] Before being twisted into yarn, the sliver is compressed by passing it through the rollers of a drawing machine. After that, the yarn is twisted into strands, which are subsequently twisted into rope. The most common rope structure is three-strand twisted rope. Braided rope is made by braiding yarn rather than twisting it into strands. A braided core and a braided cover make up double-braided rope. Plaited rope is made by braiding twisted strands. Other rope construction includes combinations of these three techniques such as a three-strand twisted core with a braided cover. The concept of forming fibers or filaments into yarn and yarn into strands or braids is fundamental to the rope-making process. However, conventional rope-making methods include large number of components, which increases the cost and complexity of the machine.

[0006] Natural aromatic fibres such as vetiver, lemongrass, citronella, lavender, and others, as well as synthetic materials, are used to make ropes. Aromatic ropes contain a variety of aromatic qualities, including a continuous pleasant scent, insect and mosquito repellant effects, and cooling properties. Vetiver (khus) leaves and roots have both been used to make fibres. But these fibers are coarse, and have limited use in industries such as textiles, or textile products. Khus has aromatic and medicinal properties, but most of the times these properties are not retained during the process of making fibers from Khus.

[0007] However, conventional rope-making methods are ineffective because the machinery used to make ropes are complex and generate thick aromatic ropes. It is impossible to weave useful aromatic objects from aromatic roots due to the inconsistency of roots with varying lengths, thicknesses, and rough textures. Existing rope-making processes need complicated equipment with a huge number of components, which increases rope/fiber costs. Existing rope-making processes fail to maintain all of aromatic’s beneficial characteristics during the rope-making process.

[0008] Therefore, there is a need for an effective method for production of rope that creates thin ropes or fibers using multiple aromatic crops. There is a need for a rope making method that willows and uses different thickness and rough texture of roots to makes an aromatic rope or aromatic fiber. A rope making method is needed for production of thin aromatic rope or aromatic fiber using various willowed fibers such as, coir, jute, hemp, cotton, and polyester. There is a need for a rope making method that consumes less time for production of ropes and requires less labour. There is a need for an automated rope making process that increases the production of aromatic ropes or aromatic fibers. There is a need for a rope making method that retains beneficial properties of aromatic crops for the production of the thin ropes or fibers.
Objectives of the invention:
[0009] The primary objective of the invention is to provide an effective method for production of ropes or fibers from willowing aromatic crop material with different thicknesses and textures.

[0010] Another objective of the invention is to provide a rope making method that is capable of the producing thin aromatic ropes or fibers by combining aromatic fibers with various willowed fibers such as, coir, jute, hemp, cotton, and polyester.

[0011] The other objective of the invention is to provide a process that wraps aromatic fibers using various natural or synthetic fibers with increased twisting to obtain thin and smooth aromatic fibers or ropes.

[0012] Yet another objective of the invention is to provide a rope making process that consumes less time for production of ropes or fibers and requires less labour.

[0013] Further objective of the invention is to provide a rope making method that does not lose beneficial properties of fibers for the production of the thin rope or fibers.

[0014] Yet another objective of the invention is to provide a rope making process can be utilized for other aromatic fibers to produce ropes or fibers for various handloom items such as curtains thereof.
Summary of the invention:
[0015] The present disclosure proposes a method for production of aromatic fibers/ropes using aromatic crops. The following presents a simplified summary in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview. It is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

[0016] In order to overcome the above deficiencies of the prior art, the present disclosure is to solve the technical problem to provide a method for production of thin aromatic ropes/fibers from aromatic crops using multiple fibers with smooth texture and consistent thickness within less time.

[0017] According to an aspect, the invention provides a method to produce multi-fiber ropes from aromatic crops. First, aromatic fibers are extracted from at least one aromatic crop material using a mixed needle arrangement in a fiber extraction unit. In specific, the aromatic crop material comprises either vetiver roots or lemongrass or citronella or lavender. Next, the aromatic fibers are subjected to sorting process, where thin and thick fibers are separated through a sorting machine. Next, the sorted aromatic fibers are mixed with at least one secondary fibers to obtain mixed fibers. In specific, small segregated roots are processed directly without mixing with another fibre to make pure vetiver root rope/fibre.

[0018] Later, the aromatic fibers and the secondary fiber are segregated through a segregator unit to obtain segregated mixed fibers. Then, the segregated mixed fibers are received at inlet of at least a pair of chambers. In specific, the aromatic fibers are wrapped with 20 to 40 % of the secondary fiber to produce the multi-fiber rope or fibers.

[0019] Next, at least one tertiary fiber from a plurality of fiber supply units is mixed with the segregated mixed fibers. In specific, the tertiary fiber and the segregated mixed fibers are wrapped together through a plurality of fiber twisting heads to obtain a mixed rope or fibers. Finally, a plurality of quaternary fibers is wrapped with the mixed rope or fibers and twisted together through at least a spinner to obtain the multi-fiber aromatic rope or fibers with smooth texture. In specific, strands of each quaternary fiber are automatically wrapped with the multi-fiber rope or fiber either with or without spinning the spinner.

[0020] Further, the secondary fiber, the tertiary fiber, and the quaternary fibers include either natural fibers or synthetic fibers such as, manila hemp, hemp, linen, cotton, coir, jute, straw, sisal, wool, polypropylene, nylon, polyesters, polyethylene, aramids and acrylics. The secondary fibers are in fiber form and the tertiary fibers and the quaternary fibers are either in thread form or in raw/ ribbon form to enable easy mixing with the aromatic fibers. In specific, the method unitizes a rope making unit that comprises the segregator unit, the plurality of fiber supply units, the plurality of fiber twisting heads, and the spinner.

[0021] Further, objects and advantages of the present invention will be apparent from a study of the following portion of the specification, the claims, and the attached drawings.
Detailed description of drawings:
[0022] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention, and, together with the description, explain the principles of the invention.

[0023] FIG. 1 illustrates an exemplary method for production of multi-fiber ropes from aromatic crops in accordance to an exemplary embodiment of the invention.
Detailed invention disclosure:
[0024] Various embodiments of the present invention will be described in reference to the accompanying drawings. Wherever possible, same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps.

[0025] The present disclosure has been made with a view towards solving the problem with the prior art described above, and it is an object of the present invention to provide a method for production of thin aromatic ropes/fibers from aromatic crops using multiple fibers with smooth texture and consistent thickness within less time.

[0026] According to an exemplary embodiment of the invention, FIG. 1 refers to an exemplary method 100 for production of multi-fiber ropes from aromatic crops. At step 102, aromatic fibers are extracted from at least one aromatic crop material using a mixed needle arrangement in a fiber extraction unit. In specific, the fiber extraction unit comprises a willowing machine that is configured with mixed needle arrangement comprising a combination of small needles and large needles. The combination of small needles and large needles in the fiber extraction unit enables willowing and carding of the aromatic crop material such as roots of various sizes simultaneously to obtain aromatic fibers. The aromatic fibers are the willowed aromatic fibers obtained by the process of disentangling and cleaning of the aromatic crop material.

[0027] Due to 6-to-22-inch-long inconsistent crop with different thickness and rough texture, the willowing process is accomplished by sending aromatic fibres or other aromatic crop into a combination of a coir willowing machine and a cotton carding machine, with big and small needle like structure. Further, the aromatic crop material comprises either vetiver roots or lemongrass or citronella or lavender or other aromatic crops.

[0028] At step 104, the aromatic fibers are subjected to sorting process, where thin and thick fibers are separated through a sorting machine. In specific, the A sorting machine is positioned after the fiber extraction unit to sort the aromatic fibers. At step 106, the sorted aromatic fibers are mixed with at least one secondary fibers to obtain mixed fibers. In specific, the thin and thick fibers sorted by the sorting machine are sent to a rope making unit for production of multi-fiber aromatic rope or aromatic fiber. The thick aromatic fibers are then mixed with other willowed fibers such as manila hemp, hemp, linen, cotton, coir, jute, straw, sisal, wool, polypropylene, nylon, polyesters, polyethylene, aramids and acrylics, thereof at a minimum of 20-40% by weight. The thin aromatic fibers are directly sent to the rope making unit without mixing with any willowed fiber.

[0029] In specific, the rope making unit is configured to receive the aromatic fibers from the fiber extraction unit and mix the aromatic fibers with the secondary fiber to obtain a multi-fiber aromatic rope or fibers. The rope making unit comprises a segregator unit, a plurality of fiber supply units, a plurality of fiber twisting heads, and at least a spinner. At step 108, the aromatic fibers and the secondary fiber are segregated uniformly through the segregator unit of the rope making unit to obtain segregated mixed fibers. In specific, the segregator unit is configured with a needle roller to segregate the aromatic fibers and the secondary fibers uniformly. Further, the segregator unit is configured with a pair of chambers that is attached at the outlet of the segregator unit. At step 110, the segregated mixed fibers are received at inlet of the pair of chambers. In specific, the aromatic fibers are wrapped with 20 to 40 % of the secondary fiber to produce the multi-fiber rope or fibers.

[0001] At step 112, at least one tertiary fiber from the fiber supply units is mixed with the segregated mixed fibers. The fiber supply units positioned below the segregator unit are configured to provide the tertiary fiber to mix with the segregated mixed fibers obtained by the segregator unit while twisting together. The fiber twisting heads are placed in front of the segregator unit, wherein each fiber twisting head is placed in front of the chambers. The tertiary fiber and the segregated mixed fibers are wrapped together through the fiber twisting heads to obtain a mixed rope or fibers. After receiving, both the fibers are twisted together, i.e., the segregated mixed fibers are wrapped with the tertiary fibers in clock-wise direction to obtain a mixed rope or fibers at the outlet of the fiber twisting heads. Further, the fiber twisting heads receives and provides uniform twisting of the mixed rope or fiber to the spinner.

[0030] At step 114, a plurality of quaternary fibers is wrapped with the mixed rope or fibers and twisted together through the spinner to obtain the multi-fiber aromatic rope or fibers with smooth texture. The spinner is configured with the quaternary fibers that are mounted on the spinner. The quaternary fibers are attached to the spinner through a plurality of pulleys. In specific, strands of each quaternary fibers are automatically wrapped with the multi-fiber rope or fiber in anti-clock-wise direction either with or without spinning the spinner. There are at least two spinners used to increase the production of the multi-fiber aromatic rope or aromatic fiber. The spinner aids to wrap the mixed rope with the quaternary fibers to increase the twisting of the multi-fiber aromatic rope to thereby reduce the thickness and roughness of the multi-fiber aromatic rope or aromatic fibers.

[0031] The multi-fiber aromatic rope or fiber is further sent through a roller guide, which is configured to receive the multi-fiber aromatic rope or fibers for further increasing the smoothness and reducing the thickness of the multi-fiber aromatic rope or fibers. In specific, the mixed rope or mixed fiber is wrapped with the quaternary fibers to increase the twisting of the multi-fiber aromatic rope or fibers to thereby reduce the thickness and roughness of the multi-fiber aromatic rope or fibers. Further, the secondary fiber, the tertiary fiber, and the quaternary fibers include either natural fibers or synthetic fibers such as, manila hemp, hemp, linen, cotton, coir, jute, straw, sisal, wool, polypropylene, nylon, polyesters, polyethylene, aramids and acrylics. The secondary fibers are in fiber form and wherein the tertiary fibers and the quaternary fibers are in thread form or raw /ribbon form to enable easy mixing with the aromatic fibers.

[0032] Numerous advantages of the present disclosure may be apparent from the discussion above. In accordance with the present disclosure, a method for production of thin aromatic ropes/fibers from aromatic crops using multiple fibers with smooth texture and consistent thickness within less time is disclosed here.

[0033] The proposed rope making method is capable of producing thin and smooth ropes or fibers from aromatic crops using multiple fibers. The proposed rope making method is capable of producing ropes or fibers from willowing aromatic crop material of different thicknesses and textures with increased twisting. The proposed rope making method produces thin and smooth aromatic rope and fibers by combining aromatic fibers with various willowed fibers such as, coir, jute, hemp, cotton, and polyester.

[0034] The proposed rope making method consumes less time for production of aromatic ropes or fibers and requires less labour. The proposed rope making method automates and increases the production of aromatic ropes or fibers. The proposed rope making method retains beneficial properties of aromatic fibers during the production of the thin and smooth rope or fibers. The proposed rope making process can be utilized for other aromatic fibers to produce ropes or fibers for various handloom items such as curtains thereof.

[0035] The proposed rope making process can be utilized for production of fragrant curtains with cooling effect made from the multi-fiber ropes/fibers. The multi-fiber ropes/fibers can be utilised for making aromatic tents with cooling effect, cool helmets, mosquito nets, fragrant home decoration item and handloom items, thereof.

[0036] It will readily be apparent that numerous modifications and alterations can be made to the processes described in the foregoing examples without departing from the principles underlying the invention, and all such modifications and alterations are intended to be embraced by this application.
