[0020] 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.

[0021] The present invention provides a weaving device for high-density Powernet separable lace fabric, comprising: a looping comb GB1, a looping comb GB2, and a looping comb GB3. The weaving structure of the high-density Powernet separable lace fabric comprises a warp straight chain weave and a mesh weave; the straight chain weave is used to connect adjacent mesh weaves, and the straight chain weave is also used for a separation effect.

[0022] The mesh structure is formed by the looping ground combs GB1 and GB2, and the straight chain structure is formed by the looping ground comb GB3.

[0023] The high-density Powernet lace weaving device of the present invention also includes a yarn guide system, which includes three yarn guide rods and three tension swing rods. Two yarn guide rods are added on the basis of the original one yarn guide rod, and the yarn of each yarn guide rod goes directly to the comb.

[0024] Furthermore, the knitting device for high-density Powernet lace fabric of the present invention preferably also includes weft insertion bars GB43 and GB45 for inserting spandex. Preferably, both weft insertion bars GB43 and GB45 are made of 280D high-modulus spandex. The basic chain number of weft insertion bar GB45 is 2-2 / 00 / / .

[0025] In addition, the high-density Powernet lace weaving device of the present invention also includes a patterned yarn comb bar PB28 and a patterned yarn comb bar PB29 for pulling spandex. Preferably, both the patterned yarn comb bar PB28 and the patterned yarn comb bar PB29 use 560D spandex yarn with a high elastic recovery rate, which is conducive to weaving and shaping.

[0026] The present invention also provides a weaving method for high-density Powernet separable lace fabric, which is characterized by: using a looping comb GB1 and a looping comb GB2 to form a mesh structure of the high-density Powernet separable lace fabric, and using a looping comb GB3 to form a straight chain structure of the high-density Powernet separable lace fabric, and the straight chain structure is used to connect adjacent mesh structures.

[0027] Specifically, the mesh structure is a loop structure formed by the reverse-padded yarns of the loop ground comb GB1 and the loop ground comb GB2. Preferably, the loop ground comb GB1 and the loop ground comb GB2 use 50D / 34F nylon filament as raw material, and the main body is woven with closed loops to reduce the risk of unraveling. Preferably, the basic chain number (i.e., the structure) of the loop ground comb GB1 is: 4-6 / 4-2 / 2-4 / 2-0 / 2-4 / 4-2 / / ; the basic chain number of the loop ground comb GB2 is: 2-0 / 2-4 / 4-2 / 4-6 / 4-2 / 2-4 / / .

[0028] Preferably, the straight braided chain structure is an open straight braided chain coil woven by a looping comb GB3 using a single nylon filament. It should be understood that the looping comb GB1 and the looping comb GB2 are used to loop and weave the main net, and the looping comb GB3 is used for the separation and de-loosening process. The basic chain number of the looping comb GB3 is: 0-2 / 2-0 / / . Furthermore, the looping comb GB3 has a needle in each flower width cycle to perform the de-loosening process, and uses 100D / 48F70D / 24F*3 nylon filament raw material. In addition, the looping comb GB3 has 2 needles on each side of each flower width cycle to perform the edge protection process, and uses 50D / 34F nylon filament raw material.

[0029] In addition, the weaving method of the high-density Powernet NetEase separable lace fabric of the present invention also includes using the weft insertion comb GB43 and the weft insertion comb GB45 to insert spandex; and also includes using the pattern yarn comb PB28 and the pattern yarn comb PB29 to pull the spandex.

[0030] Specifically, the relevant technical indicators of the high-density Powernet NetEase separation lace fabric of the present invention are as follows: A, proportion content: nylon 65-70%, spandex 30-35%; B, friction resistance color fastness (grade): dry rubbing ≥4; wet rubbing ≥4; C, washing dimensional change rate (%): warp -1 to -2%, transverse -2 to -3%; D, tensile elastic elongation (%): 90% ± 10%; E, no delamination after 25 washings, and the overall appearance remains unchanged; H, internal quality indicators such as snagging and bursting are qualified.

[0031] The present invention uses high-F ultrafine fiber yarn raw materials. This type of single fiber yarn is very fluffy, has excellent air permeability, feels smooth to the skin, has a compact structure that is not easy to fall apart, can increase resilience, and is washable and friction-resistant. The lace fabric using this raw material has the characteristics of good mesh effect, strong resilience, and is not easy to deform. This type of product will not undergo significant changes in texture due to post-processing or use.

[0032] The present invention adds two looping ground combs to the existing ground combs of a warp knitting machine. The looping ground combs adopt a three-comb looping method, and all of them thread the yarn according to a special threading method. Thus, the Powernet mesh loose lace formed by the three looping ground combs can be woven, which has the characteristics of good mesh effect, strong restoring force, and non-deformation. In order to enable the machine to achieve looping with three ground combs, a suitable motion trajectory of the main shaft cam of the Jacardo-comb warp knitting machine is designed through calculation. This enables the needle bed to add two working lines to form loops and yarn inlay motion in addition to the original one-comb looping method, thus achieving a three-comb looping method.

[0033] The warp knitting machine of this invention incorporates two self-developed active warp let-off systems, based on the existing warp let-off system. Furthermore, because the original warp knitting machine can only form loops with one ground bar at most, increasing the number of ground bar loops to three requires changing the motion trajectory of the needle bar spindle cam. This requires precise calculations to ensure that the motion trajectory and timing of the needle bar spindle cam fully meet the requirements for forming loops with three ground bars, thereby preventing missed stitches on the fabric due to inaccurate lateral movement. Furthermore, by adjusting the relevant parameters of the loop-forming mechanism of the jacquard multi-bar warp knitting machine and changing the warp yarn warping method, the formation of regular longitudinal stripes on the fabric is avoided.

[0034] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. 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.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
