Description

Technical Field

[0001] The invention relates to the technical field of textile weaving, and in particular to a jacquard plush fabric with perfect edge filling and a weaving process thereof. Background Art

[0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for home textile products. Plush products have been deeply loved by the public due to their good warmth retention, fluffy feel, low price and other characteristics. They are widely used in the field of blankets. With the development of society and electronic machinery, warp knitting jacquard machines have been widely used. People have higher requirements for the appearance of plush products and are no longer satisfied with ordinary appearance. Jacquard plush blankets came into being.

[0003] At present, jacquard plush fabrics are used to make jacquard plush blankets on the market. However, when weaving jacquard plush fabrics, due to the weaving structure, the jacquard plush area on the jacquard plush fabric cannot fully cover the base fabric of the jacquard plush fabric. There are widespread exposed areas on both sides of the base fabric of the jacquard plush fabric. Especially when the jacquard pattern is large, the exposed bottom problem on both sides of the base fabric is particularly obvious, which reduces the beauty of the jacquard plush fabric. Therefore, in order to maintain the overall beauty of the jacquard plush blanket, it is usually necessary to use the trimming method to cut the jacquard plush fabric. The exposed bottom areas on both sides are partially cut off, which increases the production process of trimming, resulting in a large amount of waste of raw materials and an increase in production costs. At the same time, the jacquard plush fabric will cause the edge structure to be damaged after the edge trimming, which will cause the strength of the fabric edge to decrease, and cause problems such as torn edges, rotten edges, and broken edges, affecting the quality of the jacquard plush fabric. Moreover, the jacquard plush fabric is damaged in the edge trimming process, and the adhesion of the plush on the edge of the fabric is reduced, resulting in hair falling. The fallen hair can be easily inhaled into the body, thereby causing harm to the human body. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a jacquard plush fabric with perfectly filled edges and a weaving process thereof, which is used to solve the technical problem in the prior art that due to the presence of exposed bottom areas on both sides of the base fabric of the jacquard plush fabric, it is necessary to use a trimming method to cut off the parts of the jacquard plush fabric with exposed bottom areas on both sides, resulting in a large amount of waste of raw materials, increased production costs, reduced quality of the jacquard plush fabric, and harm to the human body.

[0005] To achieve the above objectives, the present application embodiment adopts the following technical solutions:

[0006] On the one hand, the embodiment of the present application provides a jacquard plush fabric with perfect edge filling, comprising a base fabric and a main pattern plush area woven on the base fabric, a first filling plush area, and a second filling plush area;

[0007] The first filling plush area and the second filling plush area are respectively located on both sides of the main pattern plush area, both sides of the main pattern plush area are first contours, the side of the first filling plush area close to the main pattern plush area is the second contour, and the side of the second filling plush area close to the main pattern plush area is the third contour, the side of the first filling plush area away from the main pattern plush area and the side of the second filling plush area away from the main pattern plush area are both straight line contours that coincide with the side of the base fabric, the second contour and the third contour are the same as the first contour, and the three are parallel, so that the first filling plush area, the main pattern plush area and the second filling plush area complement each other to form a rectangular plush area with the same size and shape as the edge contour of the base fabric.

[0008] In the jacquard plush fabric with perfect edge filling described in an embodiment of the present application, the interval between the second contour and the first contour is defined as H needles, and the interval between the third contour and the first contour is defined as h needles, then H≥0 and h≥0 are satisfied, and both H and h are integers.

[0009] In a jacquard plush fabric with perfect edge filling described in an embodiment of the present application, the main pattern plush area includes m sub-pattern plush areas arranged in sequence, and the spacing between two adjacent sub-pattern plush areas is defined as W needles, then W satisfies W≥0, and m is a natural number greater than 0, and W is a natural number.

[0010] In the jacquard plush fabric with perfect edge filling described in an embodiment of the present application, the first contour is a non-linear contour.

[0011] On the other hand, the embodiment of the present application also provides a weaving process for a jacquard plush fabric with perfect edge filling, the weaving process comprising the following steps:

[0016] S5: using a double needle bed warp knitting machine to weave the non-plush yarn, main body plush yarn, first filling plush yarn and second filling plush yarn after warping according to a weaving process to obtain a grey cloth, wherein the main body plush yarn, the first filling plush yarn and the second filling plush yarn share a comb bar, which is GB3, and the GB3 is woven according to the weaving process of the main pattern plush area. During weaving, the GB3 drives the main body plush yarn, the first filling plush yarn and the second filling plush yarn to swing back and forth in the horizontal direction with the same amplitude of lateral movement law, so that the first filling plush yarn and the second filling plush yarn move upward relative to the base fabric and reciprocately weave away from and into the base fabric in the horizontal direction. The yarn storage device pulls and recovers the first filling plush yarn and the second filling plush yarn woven away from the base fabric, so that the first filling plush yarn and the second filling plush yarn woven away from the base fabric maintain tension;

[0017] S6: performing post-finishing on the grey fabric to obtain a finished fabric.

[0018] In the weaving process of a jacquard plush fabric with perfect edge filling described in an embodiment of the present application, in S2, the non-plush yarn is FDY fully drawn filament or DTY low-elastic yarn, and its single yarn fineness is 1.04pfd~3.13pfd, and the main plush yarn, the first filling plush yarn and the second filling plush yarn are all at least one of FDY fully drawn filament and DTY low-elastic yarn, and their single yarn fineness is 0.26pfd~4.16pfd.

[0019] In a knitting process for a jacquard plush fabric with perfect edge filling described in an embodiment of the present application, in S2, the yarn storage device includes a yarn rack and a yarn tension recovery device;

[0020] A yarn rack is disposed on both sides of the double needle bed warp knitting machine, and a plurality of yarn tubes are disposed on the yarn rack. The plurality of yarn tubes are vertically distributed upward perpendicular to the ground, and each of the yarn tubes stores one of the first filling plush yarn or one of the second filling plush yarn;

[0021] A yarn tension recovery device is arranged between each of the yarn racks and the double needle bed warp knitting machine, and the yarn tension recovery device comprises a shell and a plurality of tension recovery mechanisms arranged in the shell, a plurality of yarn inlets and a plurality of yarn outlets are respectively arranged on both sides of the shell, one of the yarn inlets and one of the yarn outlets are correspondingly connected to a tension recovery mechanism, and a yarn guide ring is arranged on each of the yarn inlets and the yarn outlets, and the tension recovery mechanism comprises a first fixed rotating shaft, a rotating arm, a tension roller, a fixed roller, a second fixed rotating shaft, a torsion spring, a telescopic device, a connecting rod, a brake rod and a third fixed rotating shaft, the first fixed rotating shaft and the third fixed rotating shaft are both fixedly connected to the shell, the third fixed rotating shaft is located on the first fixed rotating shaft, and one end of the rotating arm is connected to the first fixed rotating shaft The shaft is rotatably connected, and the other end is provided with a sliding long hole. The second fixed shaft is slidably connected to the sliding long hole. The tension roller is rotatably set on the second fixed shaft, and the fixed roller is rotatably set on the first fixed shaft. A torsion spring is provided at both ends. The torsion spring is sleeved on the first fixed shaft, and its two ends are respectively connected to the first fixed shaft and the rotating arm. The fixed end of the telescopic device is connected to the rotating arm, and its telescopic end is connected to the second fixed shaft to drive the second fixed shaft to make a linear reciprocating motion. One end of the connecting rod is rotatably connected to the telescopic end of the telescopic device, and the other end is rotatably connected to the brake rod. The brake rod is rotatably connected to the third fixed shaft, and a wire clamping block is provided on the end of the brake rod away from the connecting rod.

[0022] In the knitting process of the jacquard plush fabric with perfect edge filling described in the embodiment of the present application, the weaving processes of the first filling plush area, the second filling plush area and the main pattern plush area are all defined as M, and M is as follows:

[0023] M: 0—X1—0—X1 / X2—X3—X2—X3 / X4—X5—X4—X5 / ··· / X i —X i+1 —X i —X i+1 / ··· / X n —X n+1 —X n —X n+1 / / ,|X i -X i-1 |≤5 and |X i -X i+1 |≤1;

[0024] The number N1 of the first filling plush yarn and the number N2 of the second filling plush yarn satisfy the following formula:

[0025] N1=N2=[maxX i*V];

[0026] Among them, X i is a positive integer, i and n are both positive even numbers, and V is the warp penetration rate of the main pattern plush area.

[0027] In a weaving process of a jacquard plush fabric with perfect edge filling described in an embodiment of the present application, during the S5 weaving process, the knitting needles on the double needle bed warp knitting machine located outside the base fabric are removed to ensure that the first filling plush yarn and the second filling plush yarn woven away from the base fabric are not knitted onto the needle bed by the knitting needles located outside the base fabric.

[0028] In the weaving process of a jacquard plush fabric with perfect edge filling described in an embodiment of the present application, in S6, the post-finishing includes slitting the grey cloth, combing, ironing, pre-setting, dyeing, softening, drying, pulling, combing, ironing, shearing and shaking out in sequence.

[0029] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0030] 1. In the embodiment of the present application, the main pattern plush area is knitted on the base fabric, and the first filling plush area and the second filling plush area are knitted on the exposed bottom areas on both sides of the main pattern plush area, the second outline of the first filling plush area is the same as and parallel to the first outline on one side of the main pattern plush area, the third outline of the second filling plush area is the same as and parallel to the first outline on the other side of the main pattern plush area, the side of the first filling plush area away from the main pattern plush area and the side of the second filling plush area away from the main pattern plush area are both straight line outlines that coincide with the side of the base fabric, so that the first filling plush area, the main pattern plush area and the second filling plush area complement each other to form a rectangular plush area with the same size and shape as the edge outline of the base fabric, The invention solves the technical problem in the prior art that due to the presence of exposed bottom areas on both sides of the base fabric of the jacquard plush fabric, it is necessary to use a trimming method to trim the parts of the jacquard plush fabric with the exposed bottom areas on both sides, which leads to a large amount of waste of raw materials, an increase in production costs, a decrease in the quality of the jacquard plush fabric, and harm to the human body. At the same time, since the first filling plush area, the main pattern plush area and the second filling plush area are perfectly complementary, the first filling plush area and the second filling plush area are prevented from overlapping with the protruding areas on both sides of the main pattern plush area during the process of filling the exposed bottom areas on both sides of the main pattern plush area, thereby avoiding the problem of uneven plush thickness on the surface of the jacquard plush fabric, and improving the quality and appearance of the jacquard plush fabric.

[0031] 2. The embodiment of the present application solves the problem of bottom exposure of the jacquard plush fabric by setting a first filling plush area and a second filling plush area on both sides of the main pattern plush area. Compared with the cutting edge in the prior art, it not only does not destroy the structure of the edge of the jacquard plush fabric, but also makes the grey cloth of the jacquard plush fabric less likely to have stretching and tearing edges during the post-finishing process, resulting in damage and breakage of the fabric surface of the jacquard plush fabric, thereby improving the strength of the edge of the jacquard plush fabric, making the structure of the entire jacquard plush fabric more stable, and at the same time, improving the service life of products made of the jacquard plush fabric during daily use.

[0032] 3. The embodiment of the present application uses the yarn storage device arranged on both sides of the double needle bed warp knitting machine to perform warping on the first filling plush yarn and the second filling plush yarn, thereby avoiding using a group of warping heads in the warping machine alone to warp a very small number of first filling plush yarns and second filling plush yarns, resulting in the difficulty in controlling the tension of a number of first filling plush yarns and a number of second filling plush yarns, making the tension of a number of first filling plush yarns and a number of second filling plush yarns uneven, and thus causing the problem of yarn breakage and unsmooth weaving, and the yarn storage device can warp each first filling plush yarn The yarn and each second filling plush yarn are controlled separately. Compared with the tension adjustment device in the existing warping machine which can only adjust and control the whole row of yarns, it is beneficial to further reduce the probability of yarn breakage. In addition, the yarn storage device can pull and recycle the first filling plush yarn and the second filling plush yarn when the first filling plush yarn and the second filling plush yarn are woven away from the base cloth, so that the first filling plush yarn and the second filling plush yarn still maintain tension when not participating in weaving, thereby improving the yarn padding effect of the first filling plush yarn and the second filling plush yarn when they are re-woven into the base cloth.

[0033] 4. The implementation of the embodiment of the present application does not require additional combs or the selection of more complex machine models, and can be completed on the most common and simplest double-needle bed warp knitting machine. By setting the first filling plush yarn, the second filling plush yarn and the main body plush yarn to share a comb bar GB3, no matter what shape the first outline of the main pattern plush area is, the second outline of the first filling plush area close to the main body pattern plush area and the third outline of the second filling plush area close to the main body pattern plush area are the same as and parallel to the first outline, and the spacing between the first outline and the second outline, and the spacing between the first outline and the third outline are the spacing between the adjacent first filling plush yarn and the main body plush yarn on GB3. When it is necessary to change the spacing between the first filling plush area and the main body pattern plush area, it is only necessary to adjust the distance between the first filling plush yarn and the main body plush yarn on GB3. When it is necessary to change the spacing between the second filling plush area and the main body pattern plush area, it is only necessary to adjust the distance between the first filling plush yarn and the main body plush yarn on GB3. The distance between the second filling plush yarn and the main body plush yarn can be adjusted on GB3, which increases practicality and convenience of adjustment. At the same time, by arranging the first filling plush yarn, the second filling plush yarn and the main body plush yarn to share a comb GB3 and a yarn storage device, the first filling plush yarn and the second filling plush yarn woven away from the base cloth are pulled and recovered. On the premise that the first filling plush area is complementary to the main pattern plush area and the second filling plush area is complementary to the main pattern plush area, the first filling plush area and the second filling plush area each form a "curved to straight" effect on the side away from the main pattern plush area, so that the first filling plush area and the second filling plush area each have a straight line contour that coincides with the side of the base cloth, so that the first filling plush area, the main pattern plush area and the second filling plush area can perfectly cover the base cloth, effectively avoiding yarn waste and reducing the cost of product optimization for enterprises.

DETAILED DESCRIPTION

[0047] At present, jacquard plush fabrics are used to make jacquard plush blankets on the market. However, when the jacquard plush fabrics are woven in the prior art, due to the weaving structure, the main pattern plush area 20 on the jacquard plush fabric cannot fully cover the base fabric 10 of the jacquard plush fabric. There are widely exposed bottom areas 11 on both sides of the base fabric 10 of the jacquard plush fabric. The exposed bottom areas 11 are the areas on both sides of the base fabric that are not covered by the jacquard plush. For details, please refer to Fig. 9, the actual picture of the existing jacquard plush fabric, especially in the case of a large jacquard pattern, the problem of the exposed bottom of the fabric edges on both sides of the base fabric is particularly obvious. When making a jacquard plush blanket, in order to maintain the overall beauty of the jacquard plush blanket, it is usually necessary to use the trimming method to trim the exposed bottom area 11 on both sides of the jacquard plush fabric according to Figure 1 The jacquard plush fabric is cut at the cutting line in the process of cutting, which increases the production process of cutting edges, resulting in a large amount of waste of raw materials and an increase in production costs. At the same time, the jacquard plush fabric will cause the edge structure of the fabric to be damaged after cutting edges, which will cause the strength of the fabric edge to be reduced, and problems such as tearing and rupture will occur, affecting the quality of the jacquard plush fabric. Moreover, the jacquard plush fabric is damaged in the process of cutting edges, the adhesion strength of the plush at the edge of the jacquard plush fabric is reduced, and hair falling occurs. The fallen hair is easily absorbed into the body, thereby causing harm to the human body.

[0048] In view of this, the present application provides a jacquard plush fabric with perfect edge filling and a weaving process thereof to solve the problems existing in the prior art.

[0049] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0050] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0051] On the one hand, the present application provides a jacquard plush fabric with perfect edge filling, such as Figure 2 , Figure 3 and Fig.10 A jacquard plush fabric with perfect edge filling includes a base fabric 10 and a main pattern plush area 20 woven on the base fabric 10 , a first filling plush area 30 and a second filling plush area 40 .

[0052] The base fabric 10 is woven by combining a chain-knitted structure and a variable weft insertion structure. The main pattern plush area 20 includes m sub-pattern plush areas 22 arranged in sequence. The spacing between two adjacent sub-pattern plush areas is defined as W needles, and W satisfies W≥0, and m is a natural number greater than 0, and W is a natural number. When W=0, the main pattern plush area 20 is composed of n sub-pattern plush areas 22 tightly connected, and there are no empty needles between each sub-pattern plush area 22. At this time, the main pattern plush area 20 appears as "a whole". In order to improve the three-dimensional sense and aesthetics of the jacquard plush fabric, in actual use, several sub-pattern plush areas 22 can be set to different colors. When W>0, the main pattern plush area 20 appears as "interval type", that is, a number of needles are spaced between two adjacent sub-pattern plush areas 22, which can be 1 to 2 needles, which can further increase the three-dimensional sense of the jacquard plush fabric.

[0053] The first filling plush area 30 and the second filling plush area 40 are respectively located on both sides of the main pattern plush area 20, and both sides of the main pattern plush area 20 are the first contour 21. The side of the first filling plush area 30 close to the main pattern plush area 20 is the second contour 31, and the side of the second filling plush area 40 close to the main pattern plush area 20 is the third contour 41. The side of the first filling plush area 30 away from the main pattern plush area 20 and the side of the second filling plush area 40 away from the main pattern plush area 20 are both straight line contours that coincide with the side of the base fabric 10. The second contour 31 and the third contour 41 are both the same as the first contour 21, and the first contour 21, the second contour 31 and the third contour 41 are parallel, so that the first filling plush area 30, the main pattern plush area 20 and the second filling plush area 40 complement each other to form a rectangular plush area with the same size and shape as the edge contour of the base fabric 10.

[0054] Specifically, Figure 2As shown, the left side of the main pattern plush area 20 in the door width direction is defined as the first filling plush area 30, and the right side of the main pattern plush area 20 in the door width direction is defined as the second filling plush area 40, and the interval between the second contour 31 and the first contour 21 is defined as H needles, and the interval between the third contour 41 and the first contour 21 is h needles, then H≥0 and h≥0 are satisfied, and H and h are both integers, that is, the first filling plush area 30 and the second filling plush area 40 are satisfied. The first filling plush area 30 and the second filling plush area 40 are arranged adjacent to the main pattern plush area 20 (no empty needles) or spaced apart (there are empty needles). There is no cross-stack between the first filling plush area 30 and the second filling plush area 40 and the main pattern plush area 20. Preferably, the first filling plush area 30 and the second filling plush area 40 are spaced apart from the main pattern plush area 20 by 1 to 2 needles. The plush height of the rectangular plush area is 0.5 mm to 25 mm, and the surface density of the jacquard plush fabric provided in the embodiment of the present application is 200 g / m 2 ~800g / m 2 .

[0055] Among them, due to the weaving structure, the two side edges of the main pattern plush area 20 in the door width direction are both presented as a kind of outline, namely the first outline 21, so there must be some exposed bottom areas 11 on both sides of the base fabric 10 in the door width direction that are not covered by the main pattern plush area 20, and the purpose of the first filling plush area 30 and the second filling plush area 40 is to fill the exposed bottom areas 11 on both sides of the base fabric 10, by setting the right side of the first filling plush area 30 as the second outline 31, and the left side of the second filling plush area 40 as the third outline 41, the second outline 31 and the third outline 41 are both the same as and parallel to the first outline 21, and the left side of the first filling plush area 30 is a straight line outline that coincides with the left side edge of the base fabric 10, and the right side of the second filling plush area 40 is a straight line outline that coincides with the left side edge of the base fabric 10. 0, so that the exposed bottom area 11 can be filled with the least yarn consumption, maintaining the integrity of the jacquard plush fabric described in the embodiment of the present application, and avoiding the first filling plush area 30 and the second filling plush area 40 that fill the exposed bottom area 11 from stacking on both sides of the main pattern plush area 20, affecting the overall quality and appearance of the jacquard plush fabric. The first contour 21 is a non-linear contour. Specifically, the first contour 21 can be a regular wavy shape, a regular fold line shape, an irregular wavy shape, an irregular fold line shape, a shape combining a wavy shape and a fold line shape, a shape combining a wavy shape and a straight line shape, a shape combining a fold line shape and a straight line shape, and the like. The reason for setting the first contour 21 as a non-linear shape is that when the first contour 21 is a straight line, no edge filling is required.

[0056] On the other hand, Figures 2 to 8 As shown, the present application also provides a weaving process for jacquard plush fabric with perfect edge filling, and the weaving process comprises the following steps:

[0057] S1: confirming the weaving process of the woven base fabric 10 and the main pattern plush area 20 woven on the base fabric 10, and based on the weaving process of the main pattern plush area 20, confirming the weaving process of the first filling plush area 30 and the second filling plush area 40.

[0058] The weaving processes of the base fabric 10 and the main pattern plush area 20 are designed on computer design software, and the weaving processes of the first filling plush area 30 and the second filling plush area 40 are the same as the weaving process of the main pattern plush area 20.

[0059] S2: Selecting raw materials for weaving the non-plush yarns for the base fabric 10, the main plush yarns 23 for weaving the main pattern plush area 20, the first filling plush yarns 32 for weaving the first filling plush area 30, and the second filling plush yarns 42 for weaving the second filling plush area 40.

[0060] Among them, the non-plush yarn is FDY fully drawn filament or DTY low-elastic yarn, and its single yarn fineness is 1.04pfd~3.13pfd.

[0088] Further preferably, in S5, the knitting needles on the double needle bed warp knitting machine located outside the base fabric 10 are removed to ensure that the first filling plush yarn 32 and the second filling plush yarn 42 woven away from the base fabric 10 are not knitted onto the needle bed by the knitting needles located outside the base fabric 10, so as to reduce the failure rate of production and weaving.

[0089] S6: performing post-finishing on the grey fabric to obtain a finished fabric.

[0090] Specifically, in S6, the post-finishing includes, in sequence, slitting the grey cloth, combing, ironing, pre-setting, dyeing, softening, drying, napping, combing, ironing, shearing and shaking to obtain the finished fabric.

[0091] In summary, the embodiment of the present application provides a jacquard plush fabric with perfect edge filling and its weaving process, by weaving a main pattern plush area on the base fabric, and respectively weaving a first filled plush area and a second filled plush area on the exposed bottom areas on both sides of the main pattern plush area, the second outline of the first filled plush area is the same as and parallel to the first outline on one side of the main pattern plush area, the third outline of the second filled plush area is the same as and parallel to the first outline on the other side of the main pattern plush area, the side of the first filled plush area away from the main pattern plush area and the side of the second filled plush area away from the main pattern plush area are both straight line outlines that coincide with the side edge of the base fabric, so that the first filled plush area, the main pattern plush area and the second filled plush area complement each other to form a rectangular plush area with the same size and shape as the edge outline of the base fabric, which solves the problem in the prior art that due to the exposed bottom areas on both sides of the base fabric of the jacquard plush fabric, the edge cutting method needs to be used to cut off the parts of the jacquard plush fabric with the exposed bottom areas on both sides, resulting in a large amount of waste of raw materials, increased production costs, and jacquard plush The technical problem of fabric quality degradation and harm to human body is solved. At the same time, since the first filling plush area, the main pattern plush area and the second filling plush area complement each other perfectly, the first filling plush area and the second filling plush area are avoided from overlapping with the protruding areas on both sides of the main pattern plush area in the process of filling the exposed bottom areas on both sides of the main pattern plush area, thereby avoiding the occurrence of uneven plush thickness on the surface of the jacquard plush fabric, and improving the quality and appearance of the jacquard plush fabric; by arranging the first filling plush area and the second filling plush area on both sides of the main pattern plush area to solve the exposed bottom problem of the jacquard plush fabric, compared with the cutting edge in the prior art, not only does it not destroy the structure of the edge of the jacquard plush fabric, but it makes the grey cloth of the jacquard plush fabric less likely to have the problem of stretching and tearing the edge during the post-finishing process, resulting in the problem of damage and breakage of the cloth surface of the jacquard plush fabric, thereby improving the strength of the edge of the jacquard plush fabric, making the structure of the entire jacquard plush fabric more stable, and at the same time, improving the service life of products made of the jacquard plush fabric during daily use;The first filling plush yarn and the second filling plush yarn are warped by utilizing the yarn storage devices disposed on both sides of the double needle bed warp knitting machine, thereby avoiding using a group of warping heads in the warping machine alone to warp a very small number of the first filling plush yarns and the second filling plush yarns, which results in difficulty in controlling the tension of a number of the first filling plush yarns and a number of the second filling plush yarns, and causes uneven tension of a number of the first filling plush yarns and a number of the second filling plush yarns, thereby causing problems such as yarn breakage and unsmooth weaving. In addition, the yarn storage device can realize individual control of each first filling plush yarn and each second filling plush yarn, which is beneficial to further reduce the probability of yarn breakage compared to the tension adjustment device in the existing warping machine that can only adjust and control the entire row of yarns. , and the yarn storage device can pull and recycle the first filling plush yarn and the second filling plush yarn when they are woven away from the base fabric, so that the first filling plush yarn and the second filling plush yarn still maintain tension when they are not involved in weaving, thereby improving the yarn padding effect of the first filling plush yarn and the second filling plush yarn when they are re-woven into the base fabric; there is no need to add additional combs or choose more complex machine models, and it can be completed on the most common and simplest double-needle bed warp knitting machine. By setting the first filling plush yarn, the second filling plush yarn and the main body plush yarn to share a comb bar GB3, no matter what shape the first contour of the main pattern plush area is, the first filling plush area is close to the second contour of the main pattern plush area The third contour of the second filling plush area close to the main pattern plush area is the same as and parallel to the first contour, and the spacing between the first contour and the second contour, and the spacing between the first contour and the third contour are the spacing between the adjacent first filling plush yarns and the main pattern plush yarns on GB3. When it is necessary to change the spacing between the first filling plush area and the main pattern plush area, it is only necessary to adjust the distance between the first filling plush yarn and the main pattern plush yarn on GB3. When it is necessary to change the spacing between the second filling plush area and the main pattern plush area, it is only necessary to adjust the distance between the second filling plush yarn and the main pattern plush yarn on GB3, which increases practicality and convenience of adjustment. At the same time, by setting the first filling plush yarn, the second filling plush yarn and the main pattern plush yarn The plush yarns share a comb bar GB3 and a yarn storage device to pull and recycle the first filling plush yarn and the second filling plush yarn woven from the base fabric. On the premise that the first filling plush area is complementary to the main pattern plush area and the second filling plush area is complementary to the main pattern plush area, the first filling plush area and the second filling plush area each form a "curved to straight" effect on the side away from the main pattern plush area, so that the first filling plush area and the second filling plush area each have a straight line profile that coincides with the side of the base fabric, so that the first filling plush area, the main pattern plush area and the second filling plush area can perfectly cover the base fabric, effectively avoiding yarn waste and reducing the cost of product optimization for enterprises. ;
