Description

Technical Field

[0001] The utility model belongs to the technical field of underwear fabrics and relates to a warp-knitted polylactic acid fiber underwear fabric. Background Art

[0002] Underwear generally includes vests, sweatshirts, shorts, etc., which are worn under other clothes and directly contact the skin. They are one of the indispensable clothing for modern people. The weaving method of underwear fabrics is usually weft knitting. The advantage of weft knitting is that the fabrics made are more elastic and comfortable to wear without being restrained. However, weft knitted fabrics are easy to deform, and once damaged, it is easy to cause continuous damage to the fabric. The materials of underwear fabrics are usually cotton and polyester fibers. Cotton is skin-friendly and comfortable but easy to wrinkle. Polyester fiber has good wrinkle resistance, but poor moisture conductivity and poor wearing comfort. Therefore, it is necessary to design a warp knitted polylactic acid fiber underwear fabric. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a warp-knitted polylactic acid fiber underwear fabric.

[0005] The warp density is 28 strands / in.

[0006] The weaving density on the machine is 24 pieces / cm.

[0007] The finished fabric has a grammage of 160±10g / m 2 .

[0008] The fineness distribution of GB1 and GB2 is 83 dtex and 55 dtex.

[0009] The finished product density of the fabric is 16.5-17.5 pieces / cm in the transverse direction and 23.5-24.5 pieces / cm in the longitudinal direction.

[0010] Compared with the prior art, the warp-knitted polylactic acid fiber underwear fabric has the following advantages:

[0011] The utility model is woven into grey cloth by warp knitting, GB1 and GB2 respectively adopt warp pile structure and warp plain structure, which effectively improves the durability and elasticity of the fabric. The use of polylactic acid material determines the anti-allergic performance of the fabric, and it is breathable and moisture-conducting, comfortable to the touch and has good drape. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the utility model.

[0013] In the figure, 1, GB1 warp pile structure; 2, GB2 warp plain structure. DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] The warp-knitted polylactic acid fiber underwear fabric is woven by warp knitting with yarns from two combing bars, GB1 and GB2. The raw materials of GB1 and GB2 are both polylactic acid fiber yarns. GB1 adopts warp pile structure, and GB2 adopts warp plain structure. This structure design, which is very conducive to lateral contraction, ensures the elasticity of the final product, making it comparable to weft knitted fabrics to a certain extent. The number of warp heads of GB1 and GB2 is 560*5 heads, and the HKS3-EBA-E28 machine is used for weaving. The padding number of GB1 is: 1-0 / 2-3 / / , and the padding number of GB2 is: 1-2 / 1-0 / / . The warp let-off of GB1 is 1650mm / R and GB2 are 1150mm / R. In practice, the machine speed is 800-1000 rpm. The woven grey cloth can be processed through refining-dyeing-setting and other processes in subsequent processing. After a series of post-processing shrinkage, the width shrinks greatly. After setting, the fabric can be given a certain elasticity, while the size is stable and not easy to fall apart. Finally, it can have the characteristics of slight elasticity and comfort, anti-falling, size stability, bright luster, good drape, and not easy to deform. At the same time, in the dyeing process, the existing antibacterial agent is introduced, and the antibacterial molecules are directly embedded into the fiber by high temperature, so that it has a long-lasting antibacterial property and can withstand repeated washing.

[0016] The durability of this underwear fabric is obtained because of the weaving method, and the anti-allergic property is inherent in the raw material itself; at the same time, polylactic acid fiber, as a widely available renewable material, can be widely promoted.

[0017] The warp density is 28 threads / in.

[0018] The weaving density on the machine is 24 pieces / cm.

[0019] The fineness distribution of GB1 and GB2 is 83dtex and 55dtex, and their types are DTY and FDY respectively. The fineness of raw materials combined with the type makes the surface of the fabric have a cottony feel and the inner layer has a backbone, so that the weight and use of the fabric are optimized.

[0020] The finished fabric weight is 160±10g / m 2 The finished product density of the fabric is 16.5-17.5 / cm in the horizontal direction and 23.5-24.5 / cm in the vertical direction. The high vertical density design makes the fabric more compact. The fabric weight is 160±10g / m 2 , moderate weight design, not hot in summer and not cold in winter, suitable for use in all seasons.

[0021] Pieces / cm refers to coils / cm

[0022] The utility model adopts polylactic acid fiber to weave grey cloth in warp knitting manner. GB1 adopts warp pile structure and GB2 adopts warp plain structure, so that the fabric has elasticity comparable to weft knitted fabric, and at the same time, the size is stable and not easy to fall apart. The fabric is slightly elastic and comfortable, has a bright luster, good drape and is not easy to deform. The product is comfortable and durable, antibacterial and mildew-proof, skin-friendly and anti-allergic, hydrophobic and moisture-conducting, and is very suitable for infants, patients, the elderly and people with allergies.
