[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present invention provides a weaving method for a long-pile loop multi-comb warp knitting product, comprising weaving a ground tissue structure (i.e., a bottom mesh tissue structure) of the long-pile loop multi-comb warp knitting product by using two loop-forming raw materials, wherein the two loop-forming raw materials include spandex 71 and a long-pile raw material 72, the shrinkage performance of the spandex 71 is higher than the shrinkage performance of the long-pile raw material 72, and the shrinkage inconsistency of the above-mentioned two loop-forming raw materials in the fabric is used to better highlight the looping effect of the ground tissue structure, so that the long-pile raw material 72 forms long-pile loops with a towel loop effect that are randomly distributed on the front and back sides of the long-pile loop multi-comb warp knitting product.

[0023] Preferably, in the long-pile multi-comb warp knitting product, the percentage of spandex is 15-18%, the percentage of long-pile raw material is 30-37%, and the percentage of other yarns such as fancy yarn is 45-55%.

[0024] Preferably, the spandex is specifically spandex 30D / 3F; wherein the D unit refers to the standard weight in grams of 9000 meters of fiber or yarn, and the unit is denier, abbreviated as denier; in addition, the F unit refers to the number of strands (Filaments) in the textile industry, indicating how many finer filaments are in a yarn, for example, spandex 30D / 3F means that there are 3 finer filaments in this 30D spandex yarn.

[0025] The main body of spandex 30D / 3F is a straight-edge chain structure. Preferably, the chain number of the straight-edge chain structure is 1-0 / 0-1 / / . A 2-needle warp flat structure is used in the horizontal row where long pile loops are required. The chain number of the 2-needle warp flat structure is usually 1-0 / 1-2 / / or 0-1 / 2-1 / / . The spandex is used to form long pile loops and multi-comb warp knitted products with very tight elastic coils that fully retract.

[0026] Preferably, the long-pile raw material is specifically nylon long-pile fiber 40D / 34F, and the main body of nylon long-pile fiber 40D / 34F is a straight-edge chain structure, and the chain number usually used in the straight-edge chain structure is 1-0 / 0-1 / / . A 2-needle warp flat structure is used in the horizontal row where long pile loops are required, and the chain number usually used is 1-0 / 1-2 / / or 0-1 / 2-1 / / . In the weaving process of the ground tissue structure, the long-pile raw material preferably adopts an overfeeding yarn feeding method, that is, the feeding amount of the long-pile raw material is much larger than the yarn amount required for normal weaving, so as to maximize the length of the long-pile coil extension line; the long-pile raw material does not have the good shrinkage performance of spandex yarn due to its physical properties. When spandex shrinks, the long-pile raw material cannot shrink like spandex, and the long-pile raw material protrudes above the ground tissue to form a long-pile loop effect, that is, the long-pile raw material is arched in the ground tissue structure to form a loop effect. The spandex and nylon long-staple fibers of the present invention are both prior arts and will not be described in detail herein. In other embodiments, the long-staple raw materials may also be other types of long-staple raw materials of prior arts such as long-staple cotton fibers. In addition, the above two loop-forming raw materials may also be connected with other straight-edge chain structures (tissues) to form a ground tissue structure of a long-staple loop multi-comb warp knitting product. The present invention utilizes loop-forming raw materials to weave a ground tissue structure, which is a weaving method using prior art and will not be limited here.

[0027] Specifically, the two loop-forming materials are passed through two loop-forming ground combs of a warp knitting machine to weave a ground structure, and a long-pile loop effect is formed through the inconsistency of the shrinkage of the coils and the extension lines.

[0028] Preferably, during the weaving process of the ground tissue structure, the spandex is fed through the spandex tension compensation device to better avoid the spandex yarn breakage due to excessive drafting caused by the swinging of the needle bed, thereby ensuring normal weaving. Further, the spandex tension compensation device includes a warp feeding motor 1, a guide rod transmission motor 2, an active rotating guide rod 3, a steering guide rod 4, and a tension compensation swing rod 5. The guide rod transmission motor 2 is connected to the active rotating guide rod 3 to drive the active rotating guide rod 3 to rotate. The active rotating guide rod 3 is arranged between the warp feeding motor 1 and the steering guide rod 4. The steering guide rod 4 is arranged between the active rotating guide rod 3 and the tension compensation swing rod 5. The warp feeding motor 1, the guide rod transmission motor 2, the active rotating guide rod 3, the steering guide rod 4, and the tension compensation swing rod 5 of the present invention are all prior art.

[0029] Specifically, the guide rod transmission motor 2 is connected to the actively rotating guide rod 3 through gears and a transmission belt to drive the actively rotating guide rod 3 to rotate.

[0030] Specifically, the spandex tension compensation device may further include a control box, which is connected to the guide rod transmission motor 2. The speed of the guide rod transmission motor 2 can be controlled by the control box, wherein the control box may be provided with a data port connected to a computer, and the speed of the guide rod transmission motor 2 can be controlled by inputting a preset transmission ratio through an external computer, so as to control and adjust the speed of the actively rotating guide rod 3. Of course, other motor control devices in the prior art may also be used, and no excessive restrictions are made here.

[0031] The above-mentioned spandex tension compensation device can also include a yarn splitting comb 6. The tension compensation rocker arm 5 is arranged between the turning guide rod 4 and the yarn splitting comb 6. The spandex yarn of the tension compensation rocker arm 5 is transmitted to the needle bed of the warp knitting machine for weaving through the yarn splitting comb 6. The yarn splitting comb 6 is a prior art and will not be described in detail here.

[0032] Specifically, the warp let-off motor 1 is connected to a yarn drum, on which spandex yarn is wound, and the spandex yarn is transmitted to the actively rotating guide rod 3 through the warp let-off motor 1; further, the spandex yarn is transmitted to the tension compensation swing rod 5 through the steering guide rod 4. In addition, it can be understood that the tension compensation swing rod 5 can swing up and down, and specifically, the tension compensation swing rod 5 can be swung and reset by a spring. The tension compensation swing rod 5 of the present invention is a swing rod device using the prior art, and no excessive restrictions are made here.

[0033] It can be understood that by controlling the rotation speed of the guide rod drive motor 2 to control and adjust the rotation speed of the actively rotating guide rod 3, the friction force on the surface of the actively rotating guide rod 3 is used to overfeed the spandex yarn, thereby effectively eliminating the additional stretching of the spandex yarn due to the friction of the turning guide rod 4, and reserving a larger spandex stretchability for the warp knitting machine loop forming parts. That is, by adjusting the rotation speed of the actively rotating guide rod 3, the actively rotating guide rod 3 can actively reduce the stretching rate of the spandex yarn in each stroke to the minimum, thereby reducing the pulling force on the spandex yarn during the swinging of the needle bed.

[0034] In addition, during the looping process, as the needle bed continues to move, the pulling force on the warp yarn (spandex) will increase. When the needle bed moves downward to the lowest point, the force on the warp yarn reaches a peak value. The spandex yarn fineness is only 30D, which is very thin and is prone to yarn breakage. Therefore, the present invention adds a tension compensation swing rod 5 accordingly, such as Figure 3 As shown, when the needle bed swings to the highest point, the tension compensation swing rod 5 also reaches the highest point (as shown in FIG. Figure 3 At this time, the spandex yarn maintains a certain tension stored in the yarn path; when the needle bed swings down to the unlooping position, that is, the needle bed swings to the lowest point, the pulling force on the spandex yarn is relatively large, and the tension compensation swing rod 5 is in a position where the tension is relatively large as the needle bed swings down. Figure 3At this time, the spandex yarn is released as much as possible through the tension compensation swing rod 5, which reduces the pulling force of the needle bed on the spandex yarn and effectively solves the problem of spandex yarn being easily broken. In the above manner, the spandex tension compensation device of the present invention can be woven normally while ensuring that the spandex yarn feeding amount is as small as possible, so that the coils formed by the spandex can be fully retracted.

[0035] In addition, the long-pile raw material can also be fed in an overfeeding manner through the yarn feeding structure of the guide rod transmission motor 2 and the actively rotating guide rod 3, and no excessive restrictions are made here.

[0036] Compared with the prior art, the present invention provides a weaving method for a long-pile loop multi-comb warp knitting product, which has the following beneficial effects: (1) The present invention utilizes two loop-forming raw materials to weave the ground structure of the long-pile loop multi-comb warp knitting product, the two loop-forming raw materials include spandex and long-pile raw materials, and the two different shrinkage raw materials, spandex and long-pile raw materials, are combined to form long-pile loops with a towel loop effect, and the long-pile loops are distributed on the front and back sides of the fabric to give it a double-sided velvet feel. Without using extremely expensive skin-friendly raw materials such as wool, silk, and superfine cotton, the present invention allows the excellent quality of the multi-comb warp knitting product to be fully utilized, which not only greatly improves the fit and skin-friendly comfort of the product, but also the product characteristics of the double-sided velvet feel expand the fluffy design style of multi-comb warp knitting products such as lace fabrics. (2) Spandex is fed through a spandex tension compensation device, which can effectively and stably adjust the tension of the spandex yarn so that the coils formed by the spandex can fully retract. That is, the different retractability of the raw materials themselves is utilized to adjust the tension relationship between the yarns in the ground structure to achieve the best raising effect on the fabric surface, and the breakage of the spandex yarn during the weaving process is reduced to the greatest extent possible, which greatly saves the time and cost consumed by the yarn tension adjustment, effectively improves the production efficiency, and improves the product quality.
