Technical Field

The invention relates to a weaving process of a fabric, in particular to a warp knitting process based on a double-jacquard double-needle bed warp knitting machine.

Background

The traditional double-jacquard warp knitting cloth usually forms patterns on the warp knitting cloth through three forms of mesh weave, V weave and thick stable weave, wherein, when the patterns are formed by adopting the mesh weave, because meshes formed by two jacquard weaves can not coincide, the patterns are single, in addition, the patterns of the existing warp knitting cloth are usually only reflected on one side, so that the warp knitting cloth can only be used on one side, although the double-sided use of the warp knitting cloth can be realized by adjusting the materials of a surface layer, a bottom layer and a jacquard comb, the process is complex, and the cost is relatively high.

In view of the above, the applicant has made intensive studies on a warp knitting process based on a double-jacquard double-needle bed warp knitting machine, and has made the present invention.

Detailed Description

The invention will be further described with reference to specific examples:

the embodiment provides a warp knitting process based on a double-jacquard double-needle bed warp knitting machine, which comprises the following steps:

s1, preparing knitting, designing a pattern on the front and back sides of the cloth sample on a computer, the pattern can be determined according to actual needs, for example, the pattern can be a uniform mesh pattern, a gradual change type mesh pattern, a character or landscape pattern, and the pattern is converted into a BMP file that can be recognized by a double needle bar warp knitting machine, and is introduced into the double needle bar warp knitting machine.

S2, arranging guide bars, and sequentially dividing each guide bar of the double-needle-bed warp knitting machine into a first guide bar group with more than one guide bar, a second guide bar group with four guide bars, a third guide bar group with more than one guide bar and a fourth guide bar group with more than one guide bar according to the arrangement direction of the guide bars on the double-needle-bed warp knitting machine. In the present embodiment, the first, third and fourth bar groups have one bar each, in the order GB1, GB4 and GB 5; the four guide bars in the second guide bar group are JB1.1, JB1.2, JB2.1 and JB2.2 in sequence according to the arrangement direction of the guide bars on the double-needle bed warp knitting machine, wherein the JB1.1 and the JB1.2 form a first separated jacquard bar together, and the JB2.1 and the JB2.2 form a second separated jacquard bar together.

S3, yarns are threaded, and yarns threaded by the first separated jacquard comb, the first guide bar group and the third guide bar group (namely GB1, JB1.1, JB1.2 and GB4) are N-FDY200D/48F nylon semi-gloss yarns, and yarns threaded by the second separated jacquard comb and the fourth guide bar group (namely JB2.1, JB2.2 and GB5) are P-DTY200D/96F semi-gloss low-elasticity micro-net yarns, wherein the N-FDY200D/48F nylon semi-gloss yarns and the P-DTY200D/96F semi-gloss low-elasticity micro-net yarns are yarns directly purchased from the market. Of course, other yarns (such as space-variant yarns, spandex yarns, core-spun yarns, etc.) may be used instead of the above yarns, but it is necessary to ensure that the yarn used for the first split jacquard threading is the same as the yarn used for the first bar set threading, the yarn used for the second split jacquard threading is the same as the yarn used for the fourth bar set threading, and the yarn used for the first split jacquard threading is different from the yarn used for the second split jacquard threading.

In addition, GB1, GB4 and GB5 all thread in full-through, JB1.1, JB1.2, JB2.1 and JB2.2 all thread in one-through-one-empty, i.e. after each thread, a position is left and the circular threading is continued.

S4, weaving the cloth, wherein a first guide bar group is used for laying and looping yarns on a front needle bed of a double-needle-bed warp knitting machine to form a surface layer of the fabric, a fourth guide bar group is used for laying and looping yarns on a rear needle bed of the double-needle-bed warp knitting machine to form a bottom layer of the fabric, and a third guide bar group is used for alternately laying and looping yarns on the front needle bed and the rear needle bed of the double-needle-bed warp knitting machine to form connecting yarns connected between the surface layer and the bottom layer; the first split jacquard comb performs loop-padding on a front needle bed of the double-needle bed warp knitting machine, loop-padding on a back needle bed of the double-needle bed warp knitting machine or alternatively loop-padding on front and back needle beds of the double-needle bed warp knitting machine, the second split jacquard comb also performs loop-padding on the front needle bed of the double-needle bed warp knitting machine, loop-padding on the back needle bed of the double-needle bed warp knitting machine or alternatively loop-padding on the front and back needle beds of the double-needle bed warp knitting machine, specifically which needle bed loop-padding can be determined as actually needed, but it is necessary to ensure that the first split jacquard comb and the second split jacquard comb are not located on the front needle bed or on the back needle bed at the same time, and in addition, it is necessary to ensure that the loop-padding textures of JB1.1, JB1.2, JB2.1 and JB2.2 are the same and that the first split jacquard comb and the second split jacquard comb perform an offset knitting operation to exchange positions with each other, thus, equivalent tissue exchange can be realized, for example, the corresponding plain weave or mesh weave of the first separated jacquard comb and the second separated jacquard comb can be exchanged with each other, so that the product can achieve excellent color gradient effect, and for example, JB1.1, JB1.2, JB2.1 and JB2.2 are used for making through holes and semi-permeable holes, so that the effects of single color, double color and mixed color in the meshes can be obtained, because the backing weave of JB1.1, JB1.2, JB2.1 and JB2.2 is the same as the surface bottom weave when the front needle bed and the rear needle bed are seamlessly exchanged, which belongs to equivalent tissue exchange, in equivalent tissue exchange, the formed meshes or plain weave can be on the corresponding knitting needles of the front needle bed and the rear needle bed, the singleness that the original jacquard weave can only make a product with deep face is changed in the original jacquard face depth process, and the material of the face layer and/or the bottom comb bar is changed to achieve the light face and simultaneously, so that the finished product of the fabric is over-clear, the cost is saved, and the product superiority is greatly improved.

Specifically, in the embodiment, the lapping weave of GB1 is 1-0-0-0/0-1-1-1//, the lapping weave of GB4 is 1-1-1-0/0-1-1-0//, and the lapping weave of GB5 is 0-0-0-1/1-1-1-0//; the yarn-laying tissues of JB1.1, JB1.2, JB2.1 and JB2.2 are all 0-1-0-1/2-1-2-1//, wherein JB1.1, JB1.2, JB2.1 and JB2.2 are all alternately laid on the front and back needle beds of the double-needle bed warp knitting machine to form a loop, and the yarn-laying tissues are indicated by the tissues with the front needle bed and the back needle bed alternately, namely 0-1 (front needle bed) -0-1 (back needle bed)/2-1 (front needle bed) -2-1 (back needle bed)//. Furthermore, with T as the offset signal of the first and second split gagging combs and H as the non-offset signal of the first and second split gagging combs, the signals of the first and second split gagging combs are set to:

TTTHHHHT (mesh knitting on the front needle bed), or

HHTHTTHT (thick plain cloth tissue in the front needle bed), or

HHTHHHHT (thin plain weave on the front needle bed), or

THTTHTHH (mesh knitting on the back needle bed), or

THHHHTTT (thick plain cloth tissue in back needle bed), or

THHHHTHH (thin plain weave on the back needle bed).

After weaving, a fabric is obtained, which can display colors and patterns after dyeing and finishing, and the front side of the fabric is shown in figure 1, and the back side of the fabric is shown in figure 2.

The present invention is described in detail with reference to the attached drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention according to the prior art, such as changing the specific types of the yarns in the above embodiments, etc., which are within the protection scope of the present invention.
