Description

Technical Field

[0001] The invention relates to the technical field of warp knitted fabrics, and in particular to a warp knitted fabric with balanced elasticity on four sides and cut arbitrarily. Background Art

[0002] Traditional knitted warp knitted fabrics, warp knitting means weaving in the warp direction, the yarns are all warp elastic, the warp and weft elasticity are uneven, the elasticity balance cannot be achieved when wearing, the comfort is poor, and the edges will curl when cutting. Downstream companies that use this kind of fabric production need to purchase hemming tape (especially underwear companies) to sew the fabric to prevent curling, which increases the cost of clothing. They also need to be equipped with hemming tape sewing workers and ribbon sewing equipment. Hemming tape sewing workers account for 10% of the labor cost of clothing companies. Summary of the invention

[0003] In view of the defects in the prior art, the present invention provides a four-sided elastic balanced warp knitted fabric that can be cut arbitrarily to overcome the above problems.

[0004] A four-sided elastic balanced arbitrary cutting warp knitted fabric comprises a fabric body, wherein the fabric body is woven by a first comb bar GB1, a second comb bar GB2, a third comb bar GB3 and a fourth comb bar GB4 of a warp knitting machine, wherein the fabric body comprises a first weaving thread woven by the first comb bar GB1 in a full-threading yarn threading mode with a yarn pad number of 1-0 / 1-2 / / ; a second comb bar GB2 in a full-threading yarn threading mode with a yarn pad number of 1-0 / 1-2 / 1-0 / 2-3 / 2-1 / 3-4 / 3-2 / 4-5 / 4-3 / 5-6 / 5-4 / 6-7 / 6-5 / 7-8 / 7-6 / 8-9 / 8-7 / 9-10 / 8-7 / 8-9 / 7-6 / 7-8 / 6-5 / 6-7 / 5-4 / 5-6 / 4-3 / 4-5 / 3 -2 / 3-4 / 2-1 / 2-3 / / , a second yarn knitted by a threading method of 8 in and 8 out; a third yarn knitted by a third combing bar GB3 in a movement mode of 8-7 / 9-10 / 8-7 / 8-9 / 7-6 / 7-8 / 6-5 / 6-7 / 5-4 / 5-6 / 4-3 / 4-5 / 3-2 / 3-4 / 2-1 / 2-3 / 1-0 / 1-2 / 1-0 / 2-3 / 2-1 / 3-4 / 3-2 / 4-5 / 4-3 / 5-6 / 5-4 / 6-7 / 6-5 / 7-8 / 7-6 / 8-9 / / , a third yarn knitted by a threading method of 8 in and 8 out; and a fourth yarn knitted by a fourth combing bar GB4 in a movement mode of 0-2 / 3-1 / / , a threading method of full threading;

[0005] The first comb bar GB1 adopts a closed warp plain structure, the fourth comb bar GB4 adopts a heavy warp structure, and the first comb bar GB1 and the fourth comb bar GB4 are symmetrical;

[0006] The second comb bar GB2 and the third comb bar GB3 both adopt closed multi-needle variation structures, and the second comb bar GB2 and the third comb bar GB3 are symmetrical.

[0007] In order to solve the above problems, the inventor has designed this technical solution. When making this fabric, four combs (GB stands for combs) are needed. When making this fabric, two combs have 34 horizontal rows. The more horizontal rows, the greater the swing and horizontal displacement of the machine. Conventional warp knitting products are within 4 horizontal rows. Therefore, the manufacturing of this product requires very high machine precision, and the most difficult part is to design the operation coordination between the four combs. In this technical solution, the fabric is made by the above coordination of the first comb GB1, the second comb GB2, the third comb GB3 and the fourth comb GB4. The fabric has uniform elasticity on all four sides and can be 360 ​​degrees. The fabric will not curl when cut, and the elasticity on all four sides is still uniform after cutting. Therefore, when using this fabric, downstream enterprises no longer need to be equipped with hemming tape sewing workers and ribbon sewing equipment, which reduces the production costs of downstream enterprises, and reduces the total product production costs and labor costs by 20%-25%. At the same time, it reduces the production cycle of enterprises and shortens the production delivery time of clothing enterprises by 15%-20%. When producing clothing, there is no need to use hemming tape, which can achieve a more intimate fit of the fabric. At the same time, the fabric maintains uniform elasticity on all four sides, which greatly improves the comfort of wearing. By changing the organizational structure, the weaving efficiency is increased by 30%.

[0008] Preferably, the second comb bar GB2 and the third comb bar GB3 are mutually looped through the knitting wheel to form a checkered pattern. In the technical solution, the second comb bar GB2 and the third comb bar GB3 are symmetrical and the yarn is threaded in 8-through-8-through mode, and the checkered pattern is formed by the knitting wheel through the knitting wheel to achieve a breathable effect.

[0009] Preferably, the first, second and third yarns are made of chemical fiber or natural fiber, and the fourth yarn is made of elastic fiber. In this technical solution, the first, second and third yarns are made of chemical fiber or natural fiber, and the fourth yarn is made of elastic fiber, which perfectly achieves a balanced distribution of chemical fiber or natural fiber and elastic fiber. In this technical solution, the elastic fiber includes spandex and polyolefin elastic fiber.

[0023] The first comb bar GB1 adopts a closed warp plain structure, the fourth comb bar GB4 adopts a heavy warp structure, and the first comb bar GB1 and the fourth comb bar GB4 are symmetrical;

[0024] The second comb bar GB2 and the third comb bar GB3 both adopt closed multi-needle change structure, and the second comb bar GB2 and the third comb bar GB3 are symmetrical. The first comb bar GB1 adopts closed warp plain structure to prevent fabric pilling.

[0025] In this embodiment, the second comb bar GB2 and the third comb bar GB3 are looped with each other through the knitting wheel to form a checkered pattern.

[0026] In this embodiment, the first, second and third yarns are made of chemical fiber or natural fiber, and the fourth yarn is made of elastic fiber. The fourth comb bar GB4 (spandex or polyolefin elastic fiber) has a heavy warp structure to achieve a locking effect so that the product does not deform and achieves a four-way stretch effect so that people feel skin-friendly and comfortable when wearing it.

[0027] In this embodiment, the inlay yarn number is the most important and most commonly used method to express the organization structure (also called weaving structure) of the warp knitted fabric. It is mainly composed of the organization structure of the warp knitted fabric by controlling the guide bar GB-the needle front and needle back lateral movement of the yarn guide needle-inlay yarn through the lateral movement mechanism. The inlay yarn number is written according to the rule of needle front lateral movement, and is separated by the isolation symbol " / " after a coil row, that is, the numbers between coil rows are separated by " / ", and the end of a pattern cycle ends with " / / ". The organization structure of the warp knitted fabric woven with different inlay yarn numbers is different: as long as there is a different coil row in the inlay yarn number, the organization structure of the warp knitted fabric woven is different; if there are multiple different coil rows, the organization structure of the warp knitted fabric woven is more different; if the entire pattern cycle is different, the organization structure of the warp knitted fabric woven will be completely different; at the same time, if the starting coil row of the pattern cycle is different, the organization structure of the warp knitted fabric woven is also different. In the case of using AA grade raw materials in this embodiment, this embodiment is quite mature.
