Description

Natural synthetic rope made using pure cotton and coconut fiber and its manufacturing method {Fabrication method of fabrication of cloth-combustible rope made using pure cotton and coconut fiber}

One embodiment relates to a natural synthetic rope manufactured using pure cotton and coconut fiber, a manufacturing method thereof, and a natural synthetic rope.

In general, a rope is a means used for the purpose of binding an object or weaving it in a net shape to wrap an object, and this rope is used in various industries throughout the industry, and in particular, the rope is divided into wire rope and synthetic rope depending on the material used. Divided.

The wire rope is a rope manufactured to have high strength by twisting several strands of steel wire, and a typical field of use of the wire rope is used for producing a palm mat (or walking mat) in a woven state in a net shape. In addition, the synthetic rope is a rope made by twisting several strands of yarn formed of nylon, polyester, vinylon, etc., and is more flexible than steel wire, so it is mainly used in the field of binding or tying objects, preferably transplanting trees. It is used as a tree transplant net that binds the roots together with the soil to protect the roots of trees.

However, the wire rope has high strength but low flexibility, so it is not suitable for use as a tree transplant network that requires tying instead of a synthetic rope, and the synthetic rope has high flexibility but low strength, so it is used as a fall prevention net. There are disadvantages that are not suitable for the following.

Looking at the conventional technology for supplementing the above disadvantages, in the following Patent Document 1, Domestic Utility Model Publication No. 20-2009-0010085 "Natural rope", a coir rope made of coconut fiber with excellent tensile strength and flexibility By using as a core material and manufacturing several strands of jute ropes around the outer diameter of the coir rope, an eco-friendly rope with both tensile strength and flexibility was described.

However, the natural rope has excellent tensile strength and flexibility by being configured to wrap the outer diameter of the coir rope with jute rope, but the thickness of the natural rope is kept constant due to the nature of hemp fibers that are easily fluffed by water. There is a short downside to this.

Looking at another conventional technique for supplementing the above disadvantages, in the following Patent Document 2, Korean Patent Registration No. 10-1261415 "Naturally Degradable Wire Rope", the fiber layer of coconut fruit is cut into long pieces, and the fine strands are cut into pieces. A plurality of wire cores having a predetermined diameter are prepared by combining a plurality of wire cores, and the outer shell of the wire core is made of a naturally degradable resin made by mixing polypropylene, corn starch, olive oil, and sugar in the longitudinal direction of the wire core. It describes a wire rope twisted and wrapped in a screw shape according to the present invention.

The wire rope as described above is a wire rope used when farming various seaweeds including kelp, seaweed, seaweed, etc. in rivers or seas where seaweeds are cultivated. It has the advantage of being preventable, but has the disadvantage of poor flexibility.

As shown in FIGS. 1 to 4, the natural rope manufacturing method according to one embodiment includes a mixing step (S10) of separating and mixing cotton raw materials to remove foreign substances; A carding step (S20) of separating the cotton raw material entangled in the mixing step (S10) for each strand to form slivers and removing fine dust present on the surface of the slivers; A plying step (S30) of plying each of the slivers manufactured in the carding step (S20); Combing the plied slivers to improve fiber quality (S40); A spinning step (S50) of rubbing the plied slivers formed in the cotton wool step (S40) to form a cotton yarn 10 (or transverse thread 10) twisted into a thread form; a coconut thread forming step (S60) of forming a coconut thread (30) by weaving coconut fibers (20) outside the cotton yarn (10) of the cotton raw material formed in the spinning step (S50); Coconut string forming step (S70) of twisting 2 strands of each of the 8 strands of coconut thread 30 formed in the coconut thread forming step (S60) to form 4 strands of coconut string 40; and a natural rope forming step (S80) of twisting the four strands of the coconut string (40) formed in the coconut string forming step (S70) to form a natural rope (50).

Here, the natural rope manufacturing method of one embodiment relates to manufacturing a natural rope with improved flexibility while preventing environmental pollution by using cotton raw material and coconut fiber extracted from cotton, which is a natural plant. In addition to cotton raw materials, cotton, silk, wool, and raw silk may also be used. Hereinafter, for convenience of description, the cotton raw material will be mainly described.

The mixing step (S10) is a step of removing foreign substances by separating and mixing cotton raw materials extracted from cotton. It is possible to provide a high-purity cotton raw material by removing foreign substances from the cotton source through the mixing step (S10).

The carding step (S20) is a step of separating the cotton raw material entangled in the mixing step (S10) for each strand to form slivers and removing fine dust present on the surface of the slivers. The sliver is made of the cotton raw material, and means a single strand of cotton raw material (or pure cotton thread). Through the carding step (S20), fine dust on the surface of the sliver can be removed to provide sliver with high purity.

In the carding step (S20), the removal of the fine dust may be performed through a fine dust cleaning device of a natural rope manufacturing device. The fine dust cleaning device includes a fine dust cleaner body, a vibration punch unit configured to give a strong blow to a wide area by forming projections to more efficiently shake off fine dust on the surface of a plurality of slivers, and dusted fine dust A brush made of a material that can efficiently generate static electricity to catch fine dust through static electricity so that it does not blow outside, a dust collector that can efficiently catch large dust, and a HEPA filter formed to prevent the fine dust from escaping to the outside, etc. can be made with

The plying step (S30) is a step of plying each of the slivers manufactured in the carding step (S20).

The combing step (S40) is a step of increasing the fiber quality by combing the plied slivers. When the slivers are twisted into yarns in the spinning step (S50) to be described later, the slivers whose lengths are shorter than the standard value cause a decrease in the strength of the cotton yarn 10. Therefore, it is possible to easily remove slivers having a length lower than the reference value in advance through the stamping step (S40).

The spinning step (S50) is a step of forming the cotton yarn 10 twisted into a thread form by rubbing the plied slivers formed in the cotton surface step (S40).

The method for manufacturing a natural rope according to an embodiment may further include a twisting step, a roughing step, and a determining step between the smoothing step (S40) and the spinning step (S50).

The twisting step is a step of making a straight and soft yarn (or sliver) by adjusting the weight of the slivers plied with a high fiber quality in the cottoning step (S40).

The rolling step is a step of making a preliminary yarn (or preliminary sliver) by giving a minimum amount of twist to the soft yarn (or sliver) produced in the spinning step. Although the roving step can be omitted, there is a problem that the braided slivers may be cut if the spinning step (S50) is performed immediately while omitting the roving step. However, as in the present embodiment, by performing the roving step before the spinning step (S50), it is possible to prevent the problem that the plied slivers may be cut.

The determining step is a step of checking the defective state of the cotton thread 10, such as the thickness, strength, and foreign matter of the cotton thread 10 manufactured through the spinning step (S50).

According to one embodiment, the cotton yarn 10 is formed, and the coconut yarn 30 formed by weaving the coconut fiber 20 to the cotton yarn 10 forms a coconut yarn 30 having a diameter of 4 to 8 mm. to be At this time, when the cotton yarn 10 is formed and the coconut fiber 20 is woven into the cotton yarn 10 to form a coconut thread 30 having a diameter of 4 to 8 mm, the tensile strength can be improved.

The coconut fiber 20 may be manufactured through coconut. In the production of the coconut fiber 20, coconuts are collected from a coconut tree, the shells of the collected coconuts and the nuts of the coconuts are separated, and the separated coconut shells are watered and stored for 12 to 24 hours. By spraying water on the coconut shell separated by this embodiment and storing it for 12 to 24 hours, the coconut shell can be softened. Since the coconut shell is a raw material of the coconut fiber 20, it is preferable that it is appropriately soft. If the coconut shell is sprinkled with water and stored for less than 12 hours, the coconut fiber 20 is not sufficiently soft, and if the coconut shell is sprinkled with water and stored for more than 24 hours, the coconut fiber 20 becomes too soft. Then, when forming a coconut string, it may be difficult to maintain a constant shape of the coconut string. Since three or more strands of the coconut thread 30 formed in the coconut thread forming step must be twisted in order for the coconut string to maintain a constant shape, material costs may further increase.

Then, after spraying water on the shell of the separated coconut and storing it for 12 to 24 hours, the softened wet coconut shell is broken using a coir separation machine to separate the coconut fiber (coir) and coco dust. . Then, the coconut fiber (coir) can be placed in the sun for about 3-4 hours to maintain 20-25% moisture and dry. If the moisture content of the coconut fiber (coir) is maintained below about 20%, the coconut fiber may become too dry and the coconut fiber 20 may become crumbly, making it difficult to produce a soft quality coconut fiber 20. . Furthermore, when the moisture content of the coconut fiber (coir) is kept higher than about 25%, the coconut fiber 20 becomes so soft that it is difficult for the coconut string to maintain a constant shape when forming the coconut string. can

The coconut fibers 20 are then sieved using a sieving machine. This step may be a step of maintaining 20-25% moisture by placing it in the sun for about 3-4 hours and removing some of the coco dust mixed in the dried coconut fiber (coir) again. In addition, in this step, only coconut fibers 20 having a length of 5 cm or more among the coconut fibers 20 may be separated.

The coconut fibers 20 may then be compressed into a bale.

According to one embodiment, the cotton yarn 10 is characterized in that made of 0.5 ~ 1mm. At this time, if the cotton yarn 10 is 0.5 mm or less, the tensile property may be reduced, and if the cotton yarn 10 is 1 mm or more, flexibility may be reduced.

According to one embodiment, the cotton yarn 10 is twisted into a plurality of strands to form the cotton yarn 10, and the coconut fiber 20 is woven to the outside to form the coconut thread 30. At this time, when the cotton yarn 10 of 0.5 to 1 mm is twisted into a plurality of strands and the coconut fiber 20 is woven externally, the diameter of the coconut thread 30 can be increased.

The coconut thread forming step (S60) is a process of forming a coconut thread 30 by weaving several strands of coconut fiber 20 outside the cotton yarn 10 as shown in FIGS. 2 and 3, such a coconut thread forming step ( In S60 , coconut fibers 20 are woven to the outside of the cotton yarn 10 to prevent the cotton yarn 10 from being exposed to form a coconut thread 30 . The coconut fiber 20 is extracted from the husk of a coconut fruit, which is a coconut fruit. This coconut fiber 20 has a porous structure and has excellent air permeability, absorbency and waterproofness, as well as flexibility, and is particularly excellent compared to other natural fibers. It is known as a fiber with tensile strength. Therefore, the coconut thread 30 can improve the tensile strength and flexibility through the dual structure of the cotton yarn 10 and the coconut fiber 20, and can prevent environmental pollution because it is naturally decomposed. At this time, according to an example of an embodiment, the coconut thread 30 formed in the coconut thread forming step (S60) is wound around eight bobbins 60, respectively, as shown in FIG. 70) can be supplied respectively.
