A shedding-resistant double-needle bed imitation mink cashmere warp-knitted fabric and its production method

Abstract

This invention discloses a non-shedding double-needle-bed imitation mink fur warp-knitted fabric and its production method, belonging to the textile field. This invention utilizes a third comb to knit a low-pile fabric and a fourth comb to knit a high-pile fabric. The height of the low-pile fabric can be determined by the spacing between the front and rear needle beds, while the height of the high-pile fabric can be calculated by the spacing between the front and rear needle beds and the needle back lateral displacement amount of GB4. Furthermore, the high-pile and low-pile fabrics have different single-count fineness; the high-pile fabric uses lower-count, coarser single-count yarns to form stiff fibers, while the low-pile fabric uses higher-count, finer single-count yarns to form soft fibers, resulting in a layered feel that better mimics the texture of animal fur. In addition, the low-pile fabric uses matte polyester for a more realistic visual simulation effect. The simulation effect can be further enhanced by discharge dyeing to deepen the color of the high-pile fabric tips. This invention can be applied to multiple fields such as home textiles and clothing.

Description

Technical Field

[0001] This invention relates to a lint-resistant double-needle bed imitation mink cashmere warp-knitted fabric and its production method, belonging to the textile field. Background Technology

[0002] With the improvement of living standards, people have put forward higher requirements for the diversification of clothing fabrics. At present, there is a wide variety of plush fabrics on the market, and double-needle bed plush fabrics produced on double-needle bed Raschel warp knitting machines have the advantages of being thick, soft, and warm, and have become popular products in recent years. They are widely used in autumn and winter clothing, blankets, sofa fabrics and other apparel and household products, especially in the high-end clothing sector.

[0003] However, due to factors such as limited production and high prices, animal fur fabrics cannot meet the needs of the general public.

[0004] Moreover, existing double-needle bed plush fabrics are generally woven on a 5-comb double-needle bed Raschel warp knitting machine. The first two combs weave the base fabric on the front needle bed, the last two combs weave the base fabric on the back needle bed, and the third comb weaves the plush yarn between the front and back needle beds. After splitting the pile, the plush fabric is formed at the same height, resulting in a limited variety.

[0005] Furthermore, although fabrics that have been split into pile can be patterned with different textures through fancy shearing, the pile height in the direction perpendicular to the fabric is only one level. This cannot completely replicate the different heights and softness of animal fur, and it also increases the number of production steps and wastes raw materials, thus increasing production costs.

[0006] In addition, conventional double-needle bed plush fabrics use a looped loop to fix the plush, which makes it easy for the plush to fall out, causing shedding and affecting its use and appearance. Summary of the Invention

[0007] [Technical Issues]

[0008] In conventional double-needle bed plush fabrics, the pile height is uniform, which cannot completely imitate the feel of animal fur with different heights and softness; and it is also prone to shedding.

[0009] [Technical Solution]

[0010] To solve the above problems, the present invention uses a double-needle bed warp knitting machine containing 6 guide combs with electronic transverse movement to knit anti-shedding double-needle bed imitation mink cashmere warp knitted fabric; moreover, the present invention makes the anti-shedding double-needle bed imitation mink cashmere warp knitted fabric softer through structural elasticity on the process side, with a high and low pile effect, and the high and low pile is not easy to fall off.

[0011] The first objective of this invention is to provide a method for producing anti-shedding double-needle bed imitation mink cashmere warp-knitted fabric. The method involves knitting on a double-needle bed Raschel warp knitting machine. The double-needle bed Raschel warp knitting machine is equipped with 6 guide combs, arranged in the following order from front to back: GB1, GB2, GB3, GB4, GB5, and GB6. GB1 and GB2 form loops only in the front needle bed yarn, GB3 and GB4 can form loops in both the front and back needle bed yarns, and GB5 and GB6 form loops only in the back needle bed yarn.

[0012] Among them, GB1 and GB6 correspond to each other, and the same warp plain weave is used; GB2 and GB5 correspond to each other, and the same chain braid is used; GB3 uses chain braid in the front and back needle beds; GB4 uses a modified weave in the front and back needle beds and performs a certain needle back transverse shift.

[0013] GB1 and GB2 are knitted together on the front needle bed, and GB5 and GB6 are knitted together on the back needle bed to form the base fabric of the imitation mink cashmere fabric; GB3 is knitted with one loop on the front needle bed and then a loop is knitted on the corresponding back needle bed needle vertically to create a low pile; GB4 is knitted with two loops on the front needle bed and then the needle back is moved laterally a certain length to knit two loops on the back needle bed needle to create a high pile; GB3 and GB4 are knitted in an orderly manner between the front and back needle beds to form a connecting area;

[0014] After weaving, the yarn in the connecting area is split and then finished to obtain a warp-knitted fabric with two different pile heights, high and low.

[0015] In one embodiment of the present invention, the production method of the anti-shedding double-needle bed imitation mink cashmere warp-knitted fabric includes the following steps:

[0016] (1) Material selection: semi-dull polyester DTY, semi-dull polyester FDY, matte flat polyester, and semi-dull flat polyester are selected as raw materials;

[0017] (2) Warping: Warping is performed on the warping machine according to the requirements of width, width density and yarn threading rate, with a certain number of heads;

[0018] (3) Weaving: Weaving is carried out using a double-needle bed Raschel warp knitting machine;

[0019] (4) Finishing: ① Splitting; ② Combing; ③ Dyeing and finishing; ④ Ironing and polishing; ⑤ Shaping;

[0020] (5) Testing and packaging;

[0021] The selection and arrangement of the various guide bar structures and yarn threading methods during warping and weaving are as follows:

[0022] GB1 comb: 0-1-1-1 / 4-3-3-3 / 0-1-1-1 / 4-3-3-3 / 0-1-1-1 / 4-3-3-3 / / Full thread;

[0023] GB2 comb: 1-0-0-0 / 0-1-1-1 / 1-0-0-0 / 1-0-0-0 / 0-1-1-1 / 1-0-0-0 / / Full thread;

[0024] GB3 comb: 1-0-1-0 / 0-1-0-1 / 1-0-1-0 / 1-0-1-0 / 0-1-0-1 / 1-0-1-0 / / Full thread;

[0025] GB4 comb: 1-0-0-0 / 0-1-19-20 / 20-20-20-19 / 2-1-1-1 / 1-2-20-21 / 21-21-21-20 / / One thread, one empty; or 2-1-1-1 / 0-1-16-17 / 17-17-18-17 / 2-3-3-3 / 3-4-20-19 / 19-19-19-18 / / One thread, one empty;

[0026] GB5 comb: 1-1-1-0 / 0-0-0-1 / 1-1-1-0 / 1-1-1-0 / 0-0-0-1 / 1-1-1-0 / / Full thread;

[0027] GB6 comb: 0-0-0-1 / 4-4-4-3 / 0-0-0-1 / 4-4-4-3 / 0-0-0-1 / 4-4-4-3 / / Full wear.

[0028] In one embodiment of the present invention, the double-needle bed Raschel warp knitting machine is an RD6DPLM.

[0029] In one embodiment of the present invention, the yarn and comb of the single comb structure are matched as follows: GB1 and GB6 are made of semi-dull polyester DTY with woven base fabric, GB2 and GB5 are made of semi-dull polyester FDY with woven base fabric, GB3 is made of matte flat polyester FDY with low pile, and GB4 is made of low f-number semi-dull flat polyester FDY with high pile.

[0030] In one embodiment of the present invention, GB4 uses any one of the low-f-number semi-dull flat polyester FDY of 50D to 75D / 6f to 12f; GB3 uses any one of the matte flat polyester FDY of 100D to 150D / 36f to 144f; and GB1, GB6, GB2, and GB5 use any one of the semi-dull polyester FDY and DTY of 75D to 150D / 36f to 72f.

[0031] In one embodiment of the present invention, the height of low pile is determined by the front and rear needle bed spacing, and the height of high pile is determined by the front and rear needle bed spacing and the amount of lateral movement of the comb back.

[0032] In one embodiment of the present invention, the height of the low-pile pile is more than 10 mm, and the height of the high-pile pile is more than 15 mm, with a height difference between the two.

[0033] In one embodiment of the present invention, the spacing between the loop-removing plates during weaving is 20-30 mm.

[0034] In one embodiment of the present invention, the weight of the anti-shedding double-needle bed imitation mink cashmere warp-knitted fabric is changed by a reasonable combination of the bobbin spacing, the comb bar transverse displacement, the yarn threading rate, and the yarn fineness; the finished weight per square meter of the anti-shedding double-needle bed imitation mink cashmere warp-knitted fabric is 650-750 g / m². 2 .

[0035] The second objective of this invention is to prepare a lint-resistant double-needle bed imitation mink cashmere warp-knitted fabric using the method described in this invention.

[0036] The third objective of this invention is the application of the anti-shedding double-needle bed imitation mink cashmere warp-knitted fabric described herein in home textiles and apparel textiles.

[0037] In one embodiment of the present invention, the home textile products include blankets and sofa fabrics; the apparel textiles include autumn and winter outerwear.

[0038] [Beneficial Effects]

[0039] (1) Conventional 5-comb double-needle bed plush fabrics have single-comb combs, and the lack of binding effect from other combs makes the plush easy to fall off. However, the present invention is made using a double-needle bed warp knitting machine with 6 electronically shifted comb belts (electronic shift makes the change of padding structure easier). The additional plush comb can bind the previous plush comb, and by the padding method, it increases the number of loops of the plush on the base fabric, binding the base of the plush to achieve its own firmness and make it less likely to fall off.

[0040] (2) The anti-shedding double needle bed imitation mink cashmere warp-knitted fabric prepared by the present invention will form two different layers after the pile is split. The fineness of the single f of the high pile and the low pile is different. The high pile uses yarn with a lower f number and a coarser single f to form stiff hair, while the low pile uses yarn with a higher f number and a finer single f to form soft hair. The resulting pile has a layered feel and better imitates the feel of animal fur. In addition, the low pile uses matte polyester, which makes the visual simulation effect more realistic. The simulation effect can be further improved by discharge dyeing to deepen the color of the tips of the high pile. It can be applied to multiple fields such as home textiles and clothing.

[0041] (3) The present invention does not require fancy shearing to form a three-dimensional plush appearance, which can reduce production processes and waste of raw materials, thereby reducing production costs.

[0042] (4) The present invention uses the third comb (GB3) to weave low pile (short pile) and the fourth comb (GB4) to weave high pile (long pile). The height of low pile can be determined by the distance between the front and rear needle beds, and the height of high pile can be calculated and determined by the distance between the front and rear needle beds and the needle back lateral movement of GB4. The high and low pile can be designed according to the needs of the product, making the fabric feel richer.

[0043] (5) After the fabric woven by this invention is split, the yarns in the connecting area are broken to form two pile fabrics with different heights. The pile height can be changed as needed. Compared with pile products formed by fancy shearing, the production process is shortened, raw materials are saved, the production cost of finished products is reduced, and the sense of layering is stronger.

[0044] (6) The present invention utilizes the fourth comb to knit two rows continuously on the front needle bed and then two rows continuously on the rear needle bed, so that the high-pile yarn is not easily pulled out from the fabric after splitting, and at the same time, it strengthens the low-pile to a certain extent, forming a mink-like effect while being less prone to shedding.

[0167] raw material:

[0168] GB1 and GB6 comb: 150D / 72f semi-dull polyester DTY,

[0169] GB2 and GB5 comb: 150D / 36f semi-dull polyester FDY,

[0170] GB3 comb: 150D / 36f matte flat polyester FDY

[0171] GB4 comb: 75D / 8f semi-dull flat polyester FDY.

[0172] Input the organization of the yarn padding number, warp feed amount, and draft density into the computer display screen of the control cabinet, save it, load the machine file, and start the machine; after weaving, the raw fabric is obtained, weighed, bagged, and put into storage;

[0173] (4) Finishing: ① Splitting; ② Combing; ③ Dyeing and finishing; ④ Ironing and polishing; ⑤ Shaping;

[0174] (5) Testing and packaging.

[0175] Through the above process, a double-needle bed warp-knitted plush fabric with anti-shedding properties and a mink-like effect can be obtained, with a low pile height of 12mm and a high pile height of 16mm.

[0176] The specific parameters of the above process are shown in Table 4:

[0177] Table 4

[0178]

[0179] Compared with the process of Examples 1-3 and Comparative Example 1:

[0180] (1) Compared with Example 1, Example 2 did not change the raw materials of each comb bar, nor did it change the height of the low pile (i.e., the spacing of the looper did not change). It only changed the padding structure of GB4 (i.e., changed the needle back transverse shift of GB4) to achieve the purpose of changing the height of the high pile and the weight.

[0181] (2) In Example 3, the needle back transverse displacement of the raw material GB4 of each comb was not changed compared with Example 1. Only the spacing of the decoupling plate was changed to achieve the purpose of changing the difference between the low pile height and the high pile height and the weight.

[0182] (3) Compared with Example 1, Comparative Example 1 has some needle back transverse directions on GB2 and GB3, GB3 and GB4, and GB4 and GB5, which can easily lead to yarn crossover and yarn breakage during the production process.

[0183] The test was conducted according to GB / T 25880—2010, and the test results are as follows:

[0184] Table 5

[0185]

[0186] Comparative Example 2

[0187] If the number of needle back transverse shifts is the same for GB3 and GB4, then the resulting pile height will be the same, and the layering of high and low pile described in Examples 1-3 cannot be achieved.

[0188] Comparative Example 3

[0189] Conventional double-needle bed plush fabrics use a single loop to secure the plush, which makes it easy for the plush to fall off. However, in Examples 1-3, GB4 forms two loops on one side of the needle bed using a looping and padding method. This not only binds GB3 but also locks its own loop with two loops, thus preventing the plush from falling off.

[0190] Comparative Example 4

[0191] If GB3 and GB4 use the same yarn, the resulting fabric will have a consistent feel from the inside out, which cannot achieve the more realistic effect of the feel from the outside to the inside, as described in Examples 1-3, where the feel is from hard to soft.

[0192] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
