Problems solved by technology

But in the field of woven fabrics, although everyone is trying to use this new type of polyester fiber with superior properties, the result is that the elasticity is insufficient, or the thick and crisp feeling of the fabric cannot meet people's needs, or the surface style of the fabric cannot meet people's needs. People's needs, or the elastic recovery rate of the fabric cannot meet people's clothing requirements, and during the dyeing process, problems such as shrinkage and wrinkles are prone to occur

Embodiment 1

[0037] Warp yarn: 84T-14-W20E (PET yarn), weft yarn: 84T / 2-24-W80T (PBT composite yarn), weave: 3 / 3 right twill, density: warp density 282 / inch* weft density 122 root / inch for weaving, and the preparation of weft yarn 84T / 2-24-W80T: the yarn uses 110D-24F-PBT POY2 as raw material, during false twist processing, one S twist direction, one Z twist direction, two parts The yarns are fed separately through parallel yarn paths, and the yarns after false twisting are merged and entangled by two false twisters in opposite directions at an elongation ratio of 1.3 times. The total residual twist of the composite yarn is 5T / M. The boiling water shrinkage of the thread is 48%. The above gray cloth is preheated and shaped→scouring→intermediate shaping→weight reduction→dyeing→functional finishing→finishing and shaping,

[0038] Wherein preheating and setting: temperature 110 ℃.

Embodiment 2

[0047]Warp yarn: 111T-144-DTY (PET yarn), weft yarn: 84T / 2-24-W80T (PBT composite yarn), weave: 3 / 3 right twill, density: warp density 194 / inch* weft density 95 Root / inch, wherein the processing method and performance of the PBT composite yarn 84T / 2-24-W80A are the same as the weft yarn in Example 1, and then the above-mentioned gray cloth is through scouring→intermediate setting→dyeing→functional finishing→finishing and setting, and the specific process is the same Example 1. The finished product is finally made, the total tightness of the fabric is 3125, the weft elasticity of the fabric is 15% to 30%, and the elastic recovery rate of the fabric is 93%.

Embodiment 3

[0049] Warp yarn: 100T-36-W80A (PBT composite yarn), weft yarn: 100T-36-W80T (PBT composite yarn), weave: 3 / 1 right twill, density: warp density 280 / inch* weft density 128 / inch, wherein the weft yarn 100T-36-W80T (PBT composite yarn) yarn adopts 130D-36F-PBT POY 2 as raw material, and adopts an elongation ratio of 1.44 during false twist processing, and the boiling water shrinkage of the obtained PBT composite yarn The rate is 60%. The above-mentioned gray cloth is preheated and shaped → scouring → intermediate shaping → weight reduction → dyeing → functional finishing → finishing and shaping, and finally the finished product is obtained. Refer to Example 1 for key process parameters, and the dyeing temperature is 110°C.

[0050] The total tightness of the fabric is: 3871, the warp and weft elasticity is 15% to 20%, and the elastic recovery rate is 91%.

Abstract

The invention discloses high-density elastic polybutylene terephthalate (PBT) fabric and a method for producing the same. Warp yarn or/and weft yarn for weaving the PBT high-density elastic fabric is/are composite PBT yarn. One part of the composite PBT yarn is S-twisted, and the other part is Z-twisted. The total degree twist of the composite PBT yarn is 0-10T/M. The method for producing the PBT high-density elastic fabric comprises the following steps: producing composite PBT yarn, weaving the composite PBT yarn into fabric and post-processing the fabric. The composite PBT yarn is produced after two parts of original yarn are false twisted in opposite directions with the false twisting process and then are combined and interlaced. The stiff soft thick elastic PBT fabric is produced by processing, weaving and dying the composite PBT yarn.

Description

Technical field: [0001] The invention relates to a textile, in particular to a high-density elastic fabric and a production method thereof. Background technique: [0002] Polybutylene terephthalate fiber is a new type of polyester fiber. As an engineering material with excellent performance, it first attracted people's attention. With the development of textile science and technology, people have higher and higher requirements for clothing fabrics, which not only need to have high elasticity to meet the needs of human body movement during clothing, but also require a certain degree of crispness to reflect the curves and shapes of the human body during clothing. The beauty of masculinity also has a greater improvement in the comfort of touching the human body, requiring a soft touch. Therefore, polybutylene terephthalate fiber is favored by fabric designers because of its good rigidity, flexibility and elasticity. In the field of knitting, it can be said that the charm of ...
