Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings.

Example 1

A manufacturing process of warp-knitted lace one-piece one-size-fits-all underwear, including ground yarn weave, flower-line jacquard weave, jacquard weave, spandex weave, the jacquard weave, and the pattern woven by flower-line jacquard weave is exposed on the front of the fabric , the ground yarn weave is above the jacquard weave and the jacquard weave to form the skeleton of the fabric, and the spandex weave is on the back of the fabric and covered in the fabric.

The fabric is formed in a single piece, designed and woven in the style of underwear.

The fabric is divided into three regions, namely, region 1 is the lower cup edge of the underwear cup, region 2 is the cup part of the underwear, and region 3 is the shoulder strap part of the underwear. Different regions have different elasticities to meet the requirements of sports underwear .

The fabric can have a transparent and thin effect at the cups, thereby forming greater elasticity.

A production process of warp-knitted lace one-piece one-size-fits-all underwear fabric, comprising:

The ground yarn weave is woven with a single straight knitting chain to form the bottom net of the fabric. The ground yarn moves in a flower height cycle. 0-1// or 0-1/1-0//, do not use changing knitting chains to prevent the fabric from falling apart, because in one-piece underwear, the ground yarn is made of nylon-covered yarn, this yarn After the thread is woven into a loop, it is not easy to come off, and the changing ground yarn knitting chain is more obvious on the fabric, which is not beautiful. The threading method adopted is the conventional single-handle-full threading, which means that every guide needle hole on the bar is threaded;

The floral thread jacquard weave is woven from 20-84 different bars;

The Jacquard weave is woven together by two Jacquard bars, one worn and one empty, weaved together with the ground yarn on the front side, and together with the patterned jacquard weave to form a pattern according to the process design; the Jacquard bar guide needle Wearing nylon covered yarn, patterns can be woven on any area of the fabric surface according to the design pattern;

The spandex weave is formed on the reverse side of the fabric and is covered in the fabric. The spandex moves in a flower height cycle, using a small cycle of yarn lapping, the chain block number is 0-0/1-1//, and the single handle is full Put on.

The threading of the ground yarn bar and jacquard bar is made of nylon covered yarn, which is covered with 30D/24F nylon semi-gloss elastic yarn covered with 20D spandex or 40D/36F nylon semi-gloss elastic yarn 20D spandex.

The threading materials of flower combs can be freely matched according to different design styles.

Spandex bar guide needle wears 280D or 210D spandex raw material.

As shown in Figure 1, the warp-knitted lace one-piece one-size-fits-all underwear fabric has a finished product with a height of 450 mm and a width of 290 mm. This size can just cut out a piece of underwear. After simple cutting, sewing or lamination, it can be made Into an underwear ready-to-wear. In weaving production, the width of the production machine reaches 3400 mm, which can produce products with 8 cycles in the weft direction at one time, and can carry out infinite high cycle production in the radial direction. After the warp knitting machine produces the cloth, it will be finished and cut according to the requirements, and then packaged for use by the garment factory. The garment factory will cut and sew the cloth into shape according to the position on the height cycle.

The warp-knitted lace one-piece one-size-fits-all underwear fabric shown in Figure 1 is divided into three areas according to different functions. Each area has characteristic physical properties and is designed according to the requirements of ready-made garments, so as to achieve the effect of specific functions in specific positions.

The physical properties of each area are different. Area 1 is the lower edge of the underwear cup. This part needs to have a good supporting force and is not easy to deform. Therefore, it is necessary to use a flower comb in this area to achieve more full flower effect; Area 2 is the cup part of the underwear. This part needs to have good elastic stretch, so it needs to be thin and transparent. The part used for lamination after cutting;

Area 3 is the shoulder strap part of the underwear. Because most of this part is thick jacquard tissue in the radial direction, the weft density of this area is larger than that of area 1 and area 2. Generally, it is used on the Karl Mayer warp knitting machine with gauge 24E For weaving, the weft density in zone 3 is about 1.25 times the weft density in zone 1 and zone 2.

In order to achieve the special functions of the above-mentioned areas, the corresponding special production process is adopted:

The warp knitting machine used to produce this kind of products: MJ59/1, machine number 24E.

Figure 2 is a schematic diagram of the bar arrangement structure of warp-knitted lace one-piece one-size-fits-all underwear fabrics. GB1 is a ground yarn bar, which can be worn with a single handle and can be worn with 30D/24F nylon semi-gloss elastic yarn covered with 20D spandex or 40D/36F nylon The semi-gloss elastic yarn is covered with 20D spandex and is used as the bottom net of the fabric. Because the raw material of the ground yarn is more elastic, the radial elasticity of the woven fabric is better. Because the raw material of the covered yarn is woven into a coil, it will form nylon Two coils of one spandex, when the spandex in the covering yarn does not contact the spandex of the spandex bar to cause adhesion, the covering yarn is easy to fall apart. On the contrary, when adhesion occurs, the covering The nylon coil in the yarn will come loose first, and at the same time, the 20D spandex coil in this coil cannot be unraveled because it is stuck to the 280d spandex, so it will get stuck when the next coil is unraveled, and sometimes it needs to continue to unravel Only a few coils will get stuck, so this kind of fabric has good anti-scattering performance and can be cut at will;

PB2-PB58 is a floral wire comb, which consists of 8 combs to form a gathering line, a total of 7 gathering lines, which are woven into pattern patterns in an orderly manner;

JB59 and JB60 are Jacquard bars, which weave specific weft insertion structures respectively. The Jacquard bars themselves are configured according to 12E, and two sets of Jacquard bars are combined to form a full-wear number of 24E. Since the jacquard bar is equipped with piezoelectric jacquard needles, the jacquard needles have a jacquard function and can weave patterns on the surface of the fabric to increase the beauty of the fabric. The jacquard yarn can be worn with 30D/24F nylon semi-gloss elastic yarn Covering 20D spandex or 40D/36F nylon semi-gloss elastic yarn covering 20D spandex, so the woven fabric has better lateral elasticity.

GB61 is spandex bar, the bar is 24E configuration, weaving weft insertion structure, the whole bar is fully covered with 280D spandex or 210D spandex to ensure the elastic recovery of the fabric.

Figure 3 is a schematic diagram of the yarn threading and guide needle positioning structure of warp-knitted lace one-piece one-size-fits-all underwear fabrics. The ground yarn bar GB1 and the spandex bar GB61 are all worn with a single bar, and the Jacquard bar JB59 and Jacquard bar JB60 It is the needle row of 14E. From the front of the machine, the first guide needle of Jacquard bar JB59 in this case is one stitch to the right than the first guide needle of Jacquard bar JB60. The two guide bars JB59 and JB60 is combined into one set of Jacquard system, and the needle trajectory of Jacquard bar JB59 and Jacquard bar JB60 is the same. In other application cases, some of the needle tracks of Jacquard bar JB59 and Jacquard bar JB60 are the same, and some are different. The jacquard let-off volume of the tissue varies as needed.

Figure 4 is the front rendering of the warp-knitted lace one-piece one-size-fits-all underwear fabric. "Jacquard pattern 1" constitutes the rich mesh effect of the fabric. Since each needle on the Jacquard combs JB59 and JB60 can be rotated according to the instruction It can be shifted or not, so that patterns can be formed at any position of the fabric, which will not limit the development of designers. "Flower pattern 2" highlights the surface of the fabric to form a three-dimensional pattern effect.

Because the ratio of the finished product density in the radial direction to the on-machine density of this type of product can be very large, the elastic stretch of the fabric can be 2.5 times, or even 3.5 times the requirement of one-size-fits-all underwear, which meets the various elasticity of sports underwear requirements, plus the one-piece design is more convenient for cutting, reduces cutting waste, improves fabric utilization, and saves costs, and the jacquard function of jacquard and fancy thread bars ensures that the design style can be ever-changing to meet the needs of various groups of people.

The above-mentioned embodiments only express the preferred implementation of the present invention, and the description is more specific and detailed, but the present invention is not limited to these embodiments, and it should be noted that it is for those of ordinary skill in the art. Under the premise of not departing from the gist of the present invention, any improvement made falls within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
