Description

Technical Field

[0001] The invention relates to the field of warp knitted fabrics, and in particular to a method for knitting stretchable fine fiber lace fabrics and a warp knitting machine. Background Art

[0002] Clothing fabrics are constantly pursuing the trend of wearing comfort, and high-end customers are constantly making higher demands on the comfort of lace fabrics. Traditional fabrics are not smooth enough to the skin because of the coarse single fiber, and there are few air gaps between single fibers. The yarn is not fluffy enough and has poor air permeability. Fabrics woven with this kind of yarn will feel sticky after long-term wearing and are not comfortable.

[0003] Judging from the few similar products now on the market, the comfort of the products does not meet the expected needs of customers due to improper selection of raw materials; the relevant technical accumulation is not deep enough, the quality cannot be effectively controlled, the scrap rate is very high, and the weaving efficiency is low, resulting in serious waste of raw materials and resources, which is contrary to the country's policy of conservation and environmental protection that is vigorously advocated, and the comfort level is also insufficient. Summary of the invention

[0004] The invention provides a method for weaving a stretch fine fiber lace fabric and a warp knitting machine, which can produce a fluffy, soft, moisture-absorbing and perspiration-releasing, comfortable warp knitting machine with good elasticity on all sides and a stable structure that is not easily deformed and is suitable for producing a stretch fine fiber lace fabric.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A warp knitting machine for knitting soft and elastic fine fiber lace fabrics, comprising a frame, a warp feeding system, a yarn separation system, a yarn guide system and a comb component, wherein a yarn rack is provided on the top of the frame, the comb component comprises a ground comb, a jacquard comb, a spandex comb and a pattern comb, and the yarn guide system corresponds to the ground comb;

[0007] The warp letting system comprises a first warp letting system for upper fine spandex raw materials and a second warp letting system for upper ultrafine fiber raw materials, and the warp letting systems are placed on both sides of the frame;

[0008] The yarn separation system comprises a first yarn separation system for preventing the fine spandex from twisting after yarn exiting, a second yarn separation system for separating the ground yarn from the fine spandex, and a third yarn separation system for separating the jacquard from the fine spandex, and each yarn separation system is provided with a yarn separation buckle.

[0009] Furthermore, two sets of the first warp letting-off systems are provided.

[0010] Furthermore, the yarn dividing buckles of the second yarn dividing system and the third yarn dividing system are 5CM 28E yarn dividing buckles.

[0011] In one aspect, the yarn guiding system includes a yarn guiding rod and four sets of bracket bearings. The bracket bearings are balanced and the yarn guiding rod passes through the holes set on the bracket bearings. There is not much resistance to rotation, otherwise the looped spandex cannot be woven. The spandex passed through the jacquard comb should not pass through the yarn guiding rod as much as possible, but directly to the comb bar.

[0012] A method for weaving a stretchable fine fiber lace fabric, using the above-mentioned warp knitting machine for weaving, the looped ground comb and the jacquard comb are both knitted in a manner of ultrafine fiber double-threaded with fine spandex; the spandex comb is knitted in a manner of naked spandex looping, the jacquard comb double-threaded with spandex directly goes to a comb bar component; the fine spandex comes out of the disc head and is respectively separated by a first yarn separation system; the ground yarn and the jacquard are both made of 20D / 17F ultrafine fiber, and the ground yarn and the jacquard are double-threaded with 30D fine spandex, and the weft-inserted spandex is 70D / 140D spandex.

[0013] Furthermore, the single fiber denier of the ultrafine fibers used in the ground yarn and the jacquard is 0.5 to 1.04. Furthermore, when the ground net is fed with yarn, the ground yarn material is in a relaxed state.

[0014] Furthermore, the weft-inserted spandex is woven in the same direction as the jacquard yarn.

[0015] This technical solution is realized by using a ground comb and a jacquard comb to pass fine spandex, a warp feeding system, four sets of yarn separation systems and a set of yarn guide system. The warp feeding system feeds the warp to the ground comb or the jacquard comb at the same time; the four sets of yarn separation systems can prevent the fine spandex from twisting and knotting after it comes out of the yarn head, and can separate the ground yarn and the fine spandex; the jacquard and the fine spandex can also be separated to prevent the two different raw materials from affecting each other, twisting, and knotting; the bare spandex in the present invention can lock the coil well, prevent the risks of spandex flying out and coil unraveling, and at the same time, the coil of the ultra-fine denier yarn floats loosely on the surface of the fabric, with a good touch; the jacquard comb is also matched in the same way, achieving high lateral elasticity while also having a good touch; because the looped spandex eliminates the risks of spandex flying out and coil unraveling, the weft-inserted spandex can adopt the same direction padding yarn, which further improves the tactile comfort of the product.

[0020] The present invention will be described in detail below with reference to the accompanying drawings in embodiments of the present invention.

[0021] Refer to the attached Figure 1~Figure 4 A warp knitting machine for weaving soft and elastic fine fiber lace fabrics comprises a frame 1, a warp feeding system, a yarn dividing system, a yarn guiding system 2 and a comb component 4. A yarn frame 3 is provided on the top of the frame 1. The comb component comprises a ground comb 41, a jacquard comb 42, a spandex comb 43 and a pattern comb 44. The yarn guiding system 2 corresponds to the ground comb.

[0022] The warp letting-off system is placed on both sides of the frame 1, and the warp letting-off system includes a first warp letting-off system 51 for upper fine spandex raw materials and a second warp letting-off system 52 for upper ultrafine fiber raw materials;

[0023] The yarn splitting system includes two sets of first yarn splitting systems 61 for preventing the fine spandex from twisting after yarn is unthreaded, a second yarn splitting system 62 for separating the ground yarn and the fine spandex, and a third yarn splitting system 63 for separating the jacquard and the fine spandex. Specifically, one set of the first yarn splitting systems 61 is close to the first warp feeding system 51; the other set of the first yarn splitting systems 61 is close to the second warp feeding system 52; the second yarn splitting system 62 is connected to the ground comb 41, and the third yarn splitting system 63 is placed between the jacquard comb 42 and the spandex comb 43. The third yarn splitting system 63 can effectively prevent the two different raw materials from influencing each other, twisting, and knotting; each yarn splitting system is correspondingly provided with a yarn splitting buckle; wherein, the yarn splitting buckles of the second yarn splitting system 62 and the third yarn splitting system 63 are 5CM 28E yarn splitting buckles.

[0024] In addition, the yarn guiding system 2 is specifically used for spandex loop yarn guiding, including a yarn guiding rod (not marked in the figure) and four sets of bracket bearings 21. The bracket bearings 21 are balanced, and the yarn guiding rod passes through the hole set on the bracket bearings 21. In the specific design, it is ensured that the yarn guiding rod can rotate freely without too much resistance, and the ultrafine fiber and fine spandex are guided separately without affecting each other, otherwise the loop spandex cannot be woven.

[0025] A method for weaving a stretchable fine fiber lace fabric, using the above-mentioned warp knitting machine for weaving, the looped ground comb 41 and the jacquard comb 42 are both knitted in a manner of ultrafine fiber double-threaded with fine spandex; the spandex comb is knitted in a manner of naked spandex looping, the spandex double-threaded by the jacquard comb 42 directly reaches the comb bar component; the fine spandex comes out of the disc head and is respectively separated by a first yarn separation system 61; the ground yarn corresponding to the ground comb 41 and the jacquard corresponding to the jacquard comb 42 are both made of 20D / 17F ultrafine fiber, and the ground yarn and the jacquard are double-threaded with 30D fine spandex, and the weft-inserted spandex is 70D / 140D spandex.

[0026] The single fiber denier (D) of ordinary nylon raw materials is generally above 2. Although the single fiber is strong, the single fiber is relatively thick, the skin feel is not smooth enough, and there are few air gaps between single fibers, the yarn is not fluffy enough, and the air permeability is poor. The fabric woven with this yarn will feel sticky and uncomfortable after wearing for a long time. In this technical solution, the ultrafine fiber selected for the ground yarn and jacquard belongs to the newly developed ultrafine denier raw material, and the single fiber denier even reaches 0.5. The air gap between single fibers is large, the yarn is very fluffy, the air permeability is very good, and the skin feel is smooth. The looped ground yarn and jacquard yarn are made of ultrafine denier raw materials to maximize the softness and extensibility of the product. The looped ground comb and jacquard comb both use ultrafine raw materials and double-thread 30D fine spandex to make the structure compact and not easy to fall apart, and increase the recovery force. The weft-inserted spandex uses 70D / 140D spandex, which achieves strong retraction in the warp direction and can achieve different finished warp densities.

[0027] When the ground net is fed, the ground yarn material is in a relaxed state, and the coils formed are very fluffy, achieving the effect of looping, so that the surface of the fabric is very soft, and the weft-inserted spandex is woven in the same direction as the jacquard yarn, which further improves the touch comfort of the product.

[0028] In this technical solution, the bare spandex is tightly looped, and the tight spandex elastic loops can tightly lock the weft-inserted jacquard yarn and spandex yarn to prevent the yarn from running. At the same time, the jacquard is double-threaded with fine spandex to achieve high lateral elasticity while also having a good touch. Because the looped fine spandex eliminates the risk of spandex flying out and the coil coming loose, this solution is suitable for most ground mesh structures. The weft-inserted spandex can be padded in the same direction as the jacquard, and the tight spandex elastic loops can lock other yarns firmly without the risk of running. The dyeing factory can add any amount of silicone softener according to the treatment method of ultra-soft fabrics. At the same time, the same-direction process design of spandex ensures a large width, and the dyeing and finishing temperature can be appropriately reduced to ensure that the ultra-fine staple fibers are not damaged as much as possible.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
