[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts 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 structure (i.e., a bottom mesh structure) of the long-pile loop multi-comb warp knitting product using two loop-forming raw materials, wherein the two loop-forming raw materials include spandex 71 and a long-pile raw material 72, and the shrinkage performance of the spandex 71 is higher than the shrinkage performance of the long-pile raw material 72. The shrinkage inconsistency of the above-mentioned two loop-forming raw materials in the fabric is utilized to better highlight the looping effect of the ground 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 of the long-pile loop multi-comb warp knitting product.

[0023] Preferably, in the long-pile loop multi-comb warp knitted 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 used in the straight-edge chain structure is 1-0 / 0-1 / / . A 2-needle warp plain structure is used in the horizontal rows where long pile loops are required. The chain number usually used in the 2-needle warp plain structure is 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 and sufficient retraction.

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

[0028] Preferably, during the weaving process of the ground weave structure, spandex is fed through a spandex tension compensation device to effectively prevent spandex yarn breakage due to excessive drafting caused by needle bed swinging, thereby ensuring normal weaving. Furthermore, the spandex tension compensation device includes a warp let-off motor 1, a guide rod transmission motor 2, an actively rotating guide rod 3, a steering guide rod 4, and a tension compensation rocker 5. The guide rod transmission motor 2 is connected to the actively rotating guide rod 3 to drive the actively rotating guide rod 3 to rotate. The actively rotating guide rod 3 is disposed between the warp let-off motor 1 and the steering guide rod 4, and the steering guide rod 4 is disposed between the actively rotating guide rod 3 and the tension compensation rocker 5. The warp let-off motor 1, guide rod transmission motor 2, actively rotating guide rod 3, steering guide rod 4, and tension compensation rocker 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 connected to the guide rod drive motor 2. The control box can control the speed of the guide rod drive motor 2. The control box may be provided with a data port for connection to a computer. The speed of the guide rod drive motor 2 can be controlled by inputting a preset transmission ratio via an external computer, thereby controlling and adjusting the speed of the actively rotating guide rod 3. Of course, other motor control devices in the prior art may also be used, and this is not limited here.

[0031] The above-mentioned spandex tension compensation device can also include a yarn splitting comb 6. The tension compensation rocker 5 is arranged between the steering guide rod 4 and the yarn splitting comb 6. The spandex yarn of the tension compensation rocker 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 an existing technology and will not be described in detail here.

[0032] Specifically, the warp let-off motor 1 is connected to a bobbin wound with spandex yarn. The warp let-off motor 1 transmits the spandex yarn to the actively rotating guide rod 3. Furthermore, the spandex yarn is transmitted to the tension-compensating swing rod 5 via the steering guide rod 4. Furthermore, it is understood that the tension-compensating swing rod 5 can swing up and down, specifically by means of a spring to enable the tension-compensating swing rod 5 to swing back to its original position. The tension-compensating swing rod 5 of the present invention utilizes a conventional swing rod device and is not subject to further limitations herein.

[0033] It can be understood that by controlling the speed of the guide rod drive motor 2 to control and adjust the speed of the actively rotating guide rod 3, the friction on the surface of the actively rotating guide rod 3 is used to overfeed the spandex yarn, which effectively eliminates the additional stretching of the spandex yarn due to the friction of the turning guide rod 4, and reserves a larger spandex stretchability for the warp knitting machine loop forming parts. That is, by adjusting the 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 a 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 its peak. 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 rocker 5, such as Figure 3 As shown, when the needle bed reaches the highest point, the tension compensation rocker 5 also reaches the highest point (as shown in FIG. Figure 3 Position 11), at this time, the spandex yarn maintains a certain tension stored in the yarn path; when the needle bed swings down to the loop-removing position, that is, the needle bed swings to the lowest point, the pulling force on the spandex yarn is large, and the tension compensation rocker 5 is in a position where the tension is compensated as the needle bed swings downward. Figure 3At position 22, the tension compensation rocker 5 releases as much spandex yarn as possible, reducing the pulling force on the spandex yarn from the needle bed, effectively solving the problem of spandex yarn breakage. In this way, the spandex tension compensation device of the present invention can knit normally while ensuring that the spandex yarn feed amount is minimized, so that the spandex loops formed can fully retract.

[0035] In addition, long-pile raw materials can also be fed in an overfeeding manner through the yarn feeding structure of the guide rod drive 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, and the two loop-forming raw materials include spandex and long-pile raw materials. The long-pile loops similar to the towel loop effect are formed by the combination of spandex and long-pile raw materials, which are two raw materials with different shrinkage properties. 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 ultra-fine 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.

In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
