Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a warp-knitted non-shedding checkerboard-patterned jacquard fleece fabric and its production process. Background Technology

[0002] With the continuous progress and development of society, people have increasingly higher requirements for the performance of textiles, and the uses of textiles are becoming more diversified, such as for clothing, industrial use, and decoration. Plush fabric is a type of fabric with a surface covered by dense, upright, or curly pile. Its structure consists of two parts: a base fabric and a pile surface. The base fabric provides support and strength, while the pile surface is attached to the base fabric. Plush fabrics come in many varieties, each with its own characteristics. Plush fabrics produced on double-needle bed warp knitting machines possess superior qualities not found in other types of plush fabrics, such as a full and even pile surface, thickness and softness, high production efficiency, and good warmth retention. They are indispensable plush fabrics for mid-to-high-end clothing, home furnishings, toys, and other fields.

[0003] Double-needle bed warp-knitted plush is woven in one go on a warp knitting machine and then split to form the pile. However, most existing double-needle bed warp-knitted plush fabrics are woven using 5-comb or 6-comb double-needle bed Raschel warp knitting machines. The front and back four combs weave the base fabric, while only the middle one or two combs weave the plush. As a result, warp-knitted plush fabrics have a single style and few variations. Moreover, the thicker plush can easily lead to insufficient breathability and moisture permeability, which can no longer meet the increasingly complex needs. Summary of the Invention

[0004] [Technical Issues] In conventional 5- or 6-comb double-needle bed plush fabrics, the pile is formed by 1 or 2 combs. Due to the small number of combs, there are fewer pattern variations, resulting in a relatively simple fabric structure.

[0005] [Technical Solution] To address the aforementioned problems in existing technologies, this invention provides a warp-knitted, non-shedding checkerboard-patterned jacquard fleece fabric and its manufacturing process. This invention utilizes a 7-comb electronic transverse double-needle bed warp knitting machine. Three pile combs create rich jacquard patterns through yarn threading, while the fewer yarn threads created by the pile combs allow for gaps between the pile fibers, increasing the fabric's breathability and moisture permeability. In this invention, the pile yarns are firmly locked in place by the extension lines of the base fabric, reducing shedding. Furthermore, the fabric achieves a three-dimensional pile effect without the need for shearing or napping, reducing subsequent production processes and lowering costs. Moreover, given a fixed jacquard pattern, the size of the pattern can be varied to meet product requirements by changing the yarn threading and the number of horizontal rows of the pattern.

[0006] The technical solution of the present invention is as follows: The first objective of this invention is to provide a manufacturing process for a warp-knitted, non-shedding checkerboard-patterned jacquard fleece fabric, comprising the following steps: S1, Material Selection: Semi-dull polyester DTY, semi-dull polyester FDY, matte flat polyester, and matte hollow octagonal polyester are selected as raw materials; S2, Warping: The polyester yarn is warped on a warping machine according to the requirements of width, width density and yarn threading rate, with a certain number of heads. S3, Weaving: Weaving is carried out using a 7-comb double-needle bed Raschel warp knitting machine; the order from front to back of the machine is GB1, GB2, GB3, GB4, GB5, GB6, GB7. GB1 and GB2 are looped only in the front needle bed mattress yarn, GB3, GB4, and GB5 are looped in both the front and back needle bed mattress yarns, and GB6 and GB7 are looped only in the back needle bed mattress yarn. S4, finishing: ① splitting the pile; ② combing the pile; ③ dyeing and finishing; ④ heat pressing and varnishing; ⑤ setting; S5, Inspection, Packaging; The selection and arrangement of the various guide bar structures and yarn threading methods during warping and weaving are as follows: GB1 comb: 0-0-0-0 / 3-3-3-3 / 0-0-0-0 / 4-4-4-4 / / Full wear or 0-0-0-0 / 5-5-5-5 / / Full wear; GB2 comb: 1-0-0-0 / 0-1-1-1 / / Full thread; GB3 comb: (0-1-0-1 / 1-0-1-0) 12 / 4-4-4-4 / 9-9-9-9 / 14-14-14-14 / 18-18-18-18 / (22-23-22-23 / 23-22-23-22) 12 / 18-18-18-18 / 14-14-14-14 / 9-9-9-9 / 4-4-4-4 / / 2 through 30 empty 11 through; GB4 comb: (20-21-20-21 / 21-20-21-20) 6 / 18-19-19-19 / 18-17-17-17 / 16-17-17-17 / 16-15-15-15 / 14-15-15-15 / 14-13-13-13 / 12-13-13-13 / 12-11-11-11 / 10-11-11-11 / 10-9-9-9 / 8-9-9-9 / 8-7-7-7 / 6-7-7-7 / 6-5-5-5 / 2-3-3-3 / 2-1-1-1 / (0-1-0-1 / 1-0-1-0) 6 / 0-0-1-2 / 2-2-3-2 / 2-2-5-6 / 6-6-7-6 / 6-6-7-8 / 8-8-9-8 / 8-8-9-10 / 10-10-11-10 / 10-10-11-12 / 12-12-13-12 / 12-12-13-14 / 14-14-15-14 / 14-14-15-16 / 16-16-17-16 / 16-16-17-18 / 18-18-19-18 / / 16 through 4 empty 23 through GB5 comb: (0-1-0-1 / 1-0-1-0) 6 / 4-4-4-4 / 9-9-9-9 / 14-14-14-14 / 18-18-18-18 / (22-23-22-23 / 23-22-23-22) 12 / 18-18-18-18 / 14-14-14-14 / 9-9-9-9 / 4-4-4-4 / (0-1-0-1 / 1-0-1-0) 6 2 through 30 empty 11 through or (0-1-1-1 / 1-0-0-0) 6 / 4-4-4-4 / 9-9-9-9 / 14-14-14-14 / 18-18-18-18 / (22-23-22-23 / 23-22-23-22) 6 / (22-22-22-23 / 23-23-23-22) 6 / 18-18-18-18 / 14-14-14-14 / 9-9-9-9 / 4-4-4-4 / (0-1-0-1 / 1-0-1-0) 6 2 through 30 empty 11 through; GB6 comb: 1-1-1-0 / 0-0-0-1 / / Full thread; GB7 comb: 0-0-4-4 / 4-4-0-0 / 0-0-3-3 / 3-3-0-0 / / Full wear or 0-0-5-5 / 5-5-0-0 / / Full wear; Or: GB1 comb: 0-0-0-0 / 5-5-5-5 / / Full wear; GB2 comb: 1-0-0-0 / 0-1-1-1 / / Full thread; GB3 comb: (0-1-0-1 / 1-0-1-0) 12 / 4-4-4-4 / 9-9-9-9 / 14-14-14-14 / 18-18-18-18 / (22-23-22-23 / 23-22-23-22) 12 / 18-18-18-18 / 14-14-14-14 / 9-9-9-9 / 4-4-4-4 / / 2 through 35 empty 11 through; GB4 comb: (20-21-20-21 / 21-20-21-20) 6 / 18-19-19-19 / 18-17-17-17 / 16-17-17-17 / 16-15-15-15 / 14-15-15-15 / 14-13-13-13 / 12-13-13-13 / 12-11-11-11 / 10-11-11-11 / 10-9-9-9 / 8-9-9-9 / 8-7-7-7 / 6-7-7-7 / 6-5-5-5 / 2-3-3-3 / 2-1-1-1 / (0-1-0-1 / 1-0-1-0) 6 / 0-0-1-2 / 2-2-3-2 / 2-2-5-6 / 6-6-7-6 / 6-6-7-8 / 8-8-9-8 / 8-8-9-10 / 10-10-11-10 / 10-10-11-12 / 12-12-13-12 / 12-12-13-14 / 14-14-15-14 / 14-14-15-16 / 16-16-17-16 / 16-16-17-18 / 18-18-19-18 / / 16 through 9 empty 23 through GB5 comb: (0-1-1-1 / 1-0-0-0) 6 / 4-4-4-4 / 9-9-9-9 / 14-14-14-14 / 18-18-18-18 / (22-23-22-23 / 23-22-23-22) 6 / (22-22-22-23 / 23-23-23-22) 6 / 18-18-18-18 / 14-14-14-14 / 9-9-9-9 / 4-4-4-4 / (0-1-0-1 / 1-0-1-0) 6 2 through 35 empty 11 through; GB6 comb: 1-1-1-0 / 0-0-0-1 / / Full thread; GB7 comb: 0-0-5-5 / 5-5-0-0 / / Full wear.

[0007] In one embodiment of the present invention, the 3rd, 4th, and 5th combs are made of high-f-count matte flat polyester DTY or matte hollow octagonal polyester DTY filaments of 100D~150D / 144f~288f; the 1st, 2nd, 6th, and 7th combs are made of semi-dull polyester FDY filaments of 75D~100D / 36f~72f.

[0008] In one embodiment of the present invention, in step S2, the width is 160cm~180cm, the horizontal density is 7.0wpc~8.0wpc, and the yarn threading rate is based on the requirements of each pattern.

[0009] In one embodiment of the present invention, in step S3, the double needle bed Raschel warp knitting machine is RD7DPLM.

[0010] In one embodiment of the present invention, in step S3, during weaving, GB1 and GB7 correspond to each other and are woven with the same weft insertion structure; GB2 and GB6 correspond to each other and are woven with the same chain braiding structure; GB3, GB4, and GB5 are woven with different structures on the front and back needle beds. GB1 and GB2 are knitted together on the front needle bed, and GB6 and GB7 are knitted together on the back needle bed to form the base fabric of the jacquard fleece fabric. GB3 involves knitting a loop on the front and back needle beds, then knitting a loop on the corresponding back needle bed needle, repeating this cycle for a certain number of rows, and then continuing the previous action by shifting the needle back and skipping a certain number of rows. GB5 and GB3 have the same operation, but the starting weave row is different; GB4 involves knitting a loop on the front and back needle beds, then knitting a loop on the corresponding back needle bed needle, repeating this cycle for a certain number of rows, then knitting a certain number of rows on the front needle bed needle, continuing the previous steps, and finally knitting a certain number of rows on the back needle bed needle.

[0011] In one embodiment of the present invention, the connecting area formed by the knitting of GB3, GB4, and GB5 between the front and back knitting is subjected to a splitting process to obtain a plush fabric.

[0012] In one embodiment of the present invention, in step S3, GB1 and GB7 adopt a semi-dull polyester FDY with a woven base fabric chain structure, GB2 and GB6 adopt a semi-dull polyester FDY with a woven base fabric weft insertion structure, and GB3, GB4 and GB5 adopt a matte flat polyester DTY or matte hollow octagonal polyester DTY woven plush.

[0013] In one embodiment of the present invention, in step S3, GB1 and GB7 are made of 75D~100D / 36f~72f semi-dull polyester FDY with a woven base fabric chain structure, GB2 and GB6 are made of 75D~100D / 36f~72f semi-dull polyester FDY with a woven base fabric weft insertion structure, and GB3, GB4 and GB5 are made of 100D~150D / 144f~288f matte flat polyester DTY or matte hollow octagonal polyester DTY woven plush.

[0014] In one embodiment of the present invention, in step S4, the jacquard pattern structure is determined by the yarn threading method of the pile comb, and the size of the jacquard pattern is determined by the yarn threading rate of the pile comb and the height of the pattern.

[0015] The second objective of this invention is to provide a warp-knitted, non-shedding checkerboard-patterned jacquard fleece fabric produced by the above-mentioned manufacturing process.

[0016] This invention mainly changes the style, feel and weight of fabric by rationally matching yarn fineness and fiber raw materials. The non-shedding "checkers-style" cross-pattern jacquard fabric can be used for home decoration, car interiors, cleaning cloths, etc.

[0017] Beneficial effects: (1) The fabric of the present invention uses three pile combs to weave a jacquard pattern structure. The fourth comb weaves the "one" of the "cross" shape, and the third and fifth combs are combined to weave the "|" of the "cross" shape. The weaving is repeated twice at the intersection of the "one" and the "|", resulting in a thicker pile, stronger pile layering, and better three-dimensionality.

[0018] (2) When GB1, GB2, GB6, and GB7 are made of FDY polyester yarn with less elasticity and fewer f numbers, and GB3, GB4, and GB5 are made of flat DTY polyester yarn with more elasticity and more f numbers, and GB1 and GB7 adopt a five-needle weft-insertion structure, a jacquard velvet fabric with a stable base fabric structure and soft and fluffy pile can be made. As a cleaning cloth, sofa fabric, and floor mat, the stable base fabric makes it less prone to deformation and has a longer service life during daily use. At the same time, the fewer wears of the pile combs create gaps, which increases the breathability and moisture permeability of the fabric.

[0019] (3) When GB1, GB2, GB6 and GB7 are made of FDY polyester yarn with less elasticity and fewer f numbers, and GB3, GB4 and GB5 are made of hollow octagonal DTY polyester yarn with more elasticity and more f numbers, and GB1 and GB7 are made of 3-needle and 4-needle weft-insertion structure, jacquard velvet fabric with slightly elastic base fabric and relatively soft and warm plush can be made for mid-to-high-end clothing, home furnishings and other products.

[0020] (4) The present invention uses GB1, GB2, GB6 and GB7 to weave the base fabric, and GB3, GB4 and GB5 to weave the plush fabric. Then, the plush fabric is formed by splitting the pile. The root of the plush yarn of the fabric is firmly locked by the extension lines of GB1 and GB7, making it less prone to shedding. Attached Figure Description

[0024] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0025] Example 1: A non-shedding checkerboard-patterned jacquard fleece fabric is composed of the following percentages by weight: 30.3% 70D / 36f semi-dull polyester FDY and 69.7% 150D / 288f matte hollow octagonal polyester FDY.

[0026] The fabric manufacturing process includes: S1, Material Selection: 70D / 36f semi-dull polyester FDY and 150D / 288f matte hollow octagonal polyester FDY are selected as raw materials; S2, Warping: Based on a width of 170cm and a horizontal density of 8.0wpc, GB1, GB2, GB6, and GB7 have full warping, GB3 has 2 warpings with 30 gaps and 11 warpings, GB4 has 16 warpings with 4 gaps and 23 warpings, and GB5 has 2 warpings with 30 gaps and 11 warpings; the calculated number of warping heads is: GB1, GB2, GB6, and GB7 is 454×3, GB3 and GB5 is 138×3, and GB4 is 412×3.

[0027] The temperature at the warping site is 25±1℃ and the relative humidity is 65±5%. The relatively high and stable temperature and humidity help stabilize the twist of the polyester yarn and make the surface soft, preventing the yarn from getting tangled and which is beneficial to the production of warp-knitted products.

[0028] S3, Weaving: Weaving is carried out using a double-needle bed Raschel warp knitting machine; Model: Raschel warp knitting machine RD7DPLM Model number: 22 pins Width: 100 inches Spacing: 24.5mm Warp knitting structure and yarn threading method: GB1 comb: 0-0-0-0 / 3-3-3-3 / 0-0-0-0 / 4-4-4-4 / / Full wear; GB2 comb: 1-0-0-0 / 0-1-1-1 / / Full thread; GB3 comb: (0-1-0-1 / 1-0-1-0) 12 / 4-4-4-4 / 9-9-9-9 / 14-14-14-14 / 18-18-18-18 / (22-23-22-23 / 23-22-23-22) 12 / 18-18-18-18 / 14-14-14-14 / 9-9-9-9 / 4-4-4-4 / / 2 through 30 empty 11 through; GB4 comb: (20-21-20-21 / 21-20-21-20) 6 / 18-19-19-19 / 18-17-17-17 / 16-17-17-17 / 16-15-15-15 / 14-15-15-15 / 14-13-13-13 / 12-13-13-13 / 12-11-11-11 / 10-11-11-11 / 10-9-9-9 / 8-9-9-9 / 8-7-7-7 / 6-7-7-7 / 6-5-5-5 / 2-3-3-3 / 2-1-1-1 / (0-1-0-1 / 1-0-1-0) 6 / 0-0-1-2 / 2-2-3-2 / 2-2-5-6 / 6-6-7-6 / 6-6-7-8 / 8-8-9-8 / 8-8-9-10 / 10-10-11-10 / 10-10-11-12 / 12-12-13-12 / 12-12-13-14 / 14-14-15-14 / 14-14-15-16 / 16-16-17-16 / 16-16-17-18 / 18-18-19-18 / / 16 through 4 empty 23 through; GB5 comb: (0-1-0-1 / 1-0-1-0) 6 / 4-4-4-4 / 9-9-9-9 / 14-14-14-14 / 18-18-18-18 / (22-23-22-23 / 23-22-23-22) 12 / 18-18-18-18 / 14-14-14-14 / 9-9-9-9 / 4-4-4-4 / (0-1-0-1 / 1-0-1-0) 6 2 through 30 empty 11 through; GB6 comb: 1-1-1-0 / 0-0-0-1 / / Full thread; GB7 comb: 0-0-4-4 / 4-4-0-0 / 0-0-3-3 / 3-3-0-0 / / Full wear.

[0030] Input the weaving pattern, warp feed amount, and draft density into the computer display screen of the control cabinet, save the data, load the machine file, and then start the machine. After weaving, the raw fabric is obtained, weighed, bagged, and stored in the warehouse.

[0031] S4, finishing: ① splitting the pile; ② combing the pile; ③ dyeing and finishing; ④ heat pressing and varnishing; ⑤ setting; S5, Inspection, Packaging.

[0032] After the above process, the non-shedding checkerboard-patterned jacquard fleece fabric of this embodiment can be obtained. Since GB1 and GB7 adopt a 4-needle weft-insertion structure, and GB3, GB4 and GB5 adopt hollow octagonal DTY polyester yarn with greater elasticity and more f number, the fabric is soft and elastic overall. In addition, the fleece yarn is made of polyester DTY yarn with a hollow octagonal fiber cross section, so it has good warmth retention.

[0033] The specific parameters of the process in this embodiment are shown in Table 1.

[0034] Table 1

[0035] Example 2: A non-shedding checkerboard-patterned jacquard fleece fabric is composed of the following percentages by weight: 32.8% 70D / 36f semi-dull polyester FDY and 67.2% 150D / 288f matte flat polyester FDY.

[0036] The fabric manufacturing process includes: S1, Material Selection: 70D / 36f semi-dull polyester FDY and 150D / 288f matte flat polyester FDY are selected as raw materials; S2, Warping: Based on a width of 170cm and a horizontal density of 8.0wpc, GB1, GB2, GB6, and GB7 have full warping, GB3 has 2 warpings with 30 gaps and 11 warpings, GB4 has 16 warpings with 4 gaps and 23 warpings, and GB5 has 2 warpings with 30 gaps and 11 warpings; the calculated number of warping heads is: GB1, GB2, GB6, and GB7 is 454×3, GB3 and GB5 is 138×3, and GB4 is 412×3.

[0037] The temperature at the warping site is 25±1℃ and the relative humidity is 65±5%. The relatively high and stable temperature and humidity help stabilize the twist of the polyester yarn and make the surface soft, preventing the yarn from getting tangled and which is beneficial to the production of warp-knitted products.

Since the weft insertion process of the base fabric is combined with 5 needle weft insertion, the fabric as a whole has a certain shape retention. The fabric has good breathability and moisture permeability. Compared with the fleece fabric of other embodiments of the present invention, the breathability and moisture permeability of this fabric can be increased by 10% to 20%.

[0043] The specific parameters of the process in this embodiment are shown in Table 2.

[0044] Table 2

[0045] Example 3: A non-shedding checkerboard-patterned jacquard fleece fabric is composed of the following percentages by weight: 23.3% of 70D / 36f semi-dull polyester FDY and 76.7% of 150D / 288f matte flat polyester FDY.

[0046] The fabric manufacturing process includes: S1, Material Selection: 70D / 36f semi-dull polyester FDY and 150D / 288f matte flat polyester FDY are selected as raw materials; S2, Warping: Based on a width of 170cm and a horizontal density of 8.0wpc, GB1, GB2, GB6, and GB7 have full warping, GB3 has 2 warpings with 30 gaps and 11 warpings, GB4 has 16 warpings with 4 gaps and 23 warpings, and GB5 has 2 warpings with 30 gaps and 11 warpings; the calculated number of warping heads is: GB1, GB2, GB6, and GB7 is 454×3, GB3 and GB5 is 138×3, and GB4 is 412×3.

[0047] The temperature at the warping site is 25±1℃ and the relative humidity is 65±5%. The relatively high and stable temperature and humidity help stabilize the twist of the polyester yarn and make the surface soft, preventing the yarn from getting tangled and which is beneficial to the production of warp-knitted products.

[0052] Through the above processes, the non-shedding "checkerboard-style" cross-shaped pattern jacquard plush fabric of this embodiment can be obtained. Among them, since three plush combs participate in the plush weaving at the intersection of the "one" and "vertical bar" of the "cross", the plush at this place will be thicker and the three-dimensional sense of the plush is stronger.

[0053] The specific parameters of the process of this embodiment are shown in Table 3.

[0054] Table 3

[0055] Comparative Example 1: A non-shedding checkerboard-style cross-shaped pattern jacquard plush fabric consists of the following mass percentages: 30.3% of 70D / 36f semi-dull polyester FDY and 69.7% of 150D / 288f dull hollow octagonal polyester FDY.

[0056] The preparation process of this fabric includes: S1, Material selection: Select 70D / 36f semi-dull polyester FDY and 150D / 288f dull hollow octagonal polyester FDY as raw materials; S2, Warping: According to a width of 170 cm, a horizontal density of 8.0 wpc, full threading for GB1, GB2, GB6, and GB7, 2 threading and 30 empty and 11 threading for GB3, 16 threading and 4 empty and 23 threading for GB4, and 2 threading and 30 empty and 11 threading for GB5; Calculate the number of warping beams: 454×3 for GB1, GB2, GB6, and GB7, 138×3 for GB3 and GB5, and 412×3 for GB4.

[0057] The temperature at the warping site is 25±1°C, and the relative humidity is 65±5%. Higher and stable temperature and humidity help to stabilize the twist of polyester yarns and make the surface soft, avoid entanglement between yarns, and are beneficial to the production of warp knitting products.

[0063] Table 4

[0064] In Example 2, compared to Example 1, the raw material of the pile yarn in GB3, GB4, and GB5 was changed to matte flat polyester, the yarn threading method was changed, and the padding structure of GB1 and GB7 was also changed (i.e., from 4-needle weft padding in Example 1 to 5-needle weft padding in Example 2), thereby increasing the fabric's durability and improving its breathability and moisture permeability. In Example 3, compared to Example 1, only the padding method in certain rows of GB5 was changed, increasing the amount of pile in the patterned areas to change the pile thickness and three-dimensionality. In Comparative Example 1, compared to Example 1, the needle back transverse movement direction on certain needles in GB3 and GB4; GB4 and GB5; and GB5 and GB6 of Comparative Example 1 was opposite, which easily led to yarn crossing and breakage during the production process.

[0065] The embodiments provided above are not intended to limit the scope of the invention, nor are the described steps intended to limit the order of execution. Any obvious modifications made to the invention by those skilled in the art based on existing common knowledge also fall within the scope of protection defined by the claims.
