Problems solved by technology

However, at present, due to the lack of clear analysis of the influence of fabric design and post-finishing on fiber elasticity and fabric style, and the process is not perfect, the PBT fabrics produced by general fabric design and processing will have poor elasticity (below 15%). Dimensional stability is poor (dry heat shrinkage is ±4 to ±5%, boiling water shrinkage is ±4 to ±5%), or the fabric surface is uneven and wrinkled and other defects
Limits the development of PBT fiber in the textile field

Embodiment 1

[0042] 1) Yarn: warp yarn: 150D-48F-DTY (PET) interlacing number 95 pcs / m

[0043] Weft yarn: 75D-24F-PBT interlacing number 25 / m

[0044] 2) Fabric specifications and weaving

[0045] Weave: 2 / 2 Twill

[0046] Density: warp density * weft density = 100 * 82 / 2.54cm

[0047] Warp tightness: 1245, weft tightness: 710

[0048]Mixing ratio: PET / PBT=23 / 77

[0049] Weaving on an air-jet loom with 4 pieces of threading

[0050] 3) finishing method after dyeing comprises the following steps:

[0051] A. Scouring: Use 4% sodium hydroxide hot lye and soaping agent (non-cationic surfactant GQ008) to remove the size, dirt and shrink the fabric to a certain extent. The temperature is 95 degrees and the processing time is 60 seconds

[0052] B. Intermediate setting: The scouring and drying cloth is subjected to form stabilization treatment. The temperature is 180 degrees and the time is 60 seconds

[0053] C. Dyeing process: use 120 degrees down dyeing medium color, dyeing time i...

Embodiment 2

[0057] An elastic fabric of polybutylene terephthalate fiber, the warp and weft yarns that make up the fabric are polybutylene terephthalate false-twisted processed yarns, and the content of polybutylene terephthalate fiber accounts for 100% by weight; or blended yarns made of polybutylene terephthalate false-twisted processed yarn and other fibers for warp and weft, and polybutylene terephthalate fiber content accounts for 20-95% of the total fabric weight (eg 20%, 50%, 95%).

[0058] The tightness of the fabric is 700-2000 (eg 700, 1300, 2000). The monofilament fineness of polybutylene terephthalate fiber is 0.5-5.6dtex (eg 0.5dtex, 3dtex, 5.6dtex). The number of entanglements of the weft yarns is 0 to 80 / m (Example 0, 40, 80), and the number of entanglements of the warp yarns is 50 to 120 / m (Examples 50, 80, 120).

[0059] Above-mentioned fabric carries out finishing after dyeing through the same method as embodiment 1, and the modulus of elasticity of the fabric obtained...

Abstract

The invention discloses an elastic textile of polybutylene terephthalate (PBT) fiber. Either warp yarn or weft yarn made up of the textile is PBT fabricated processing yarn or blended fibber yarn of PBT fabricated processing yarn and other fibers. The elastic textile of the invention not only has good elasticity percentage, elastic recovery percentage and size stability, but also has neat cloth surface, soft texture, etc. The elastic textile can fully present beautiful body line, and greatly enhance extension breadth for exercise and reduces friction with and irritability to the skin when worn.

Description

technical field [0001] The present invention relates to an elastic fabric. Background technique [0002] Polybutylene terephthalate (PBT) fiber is a new modified polyester fiber. As an engineering material with excellent performance, it first attracted people's attention. In recent years, with the development of differentiated fibers, the excellent elasticity and other characteristics of PBT fibers have attracted more and more people's attention. However, at present, due to the lack of clear analysis of the influence of fabric design and finishing on fiber elasticity and fabric style, and the process is not perfect, the PBT fabrics produced by general fabric design and processing will have poor elasticity (below 15%). Dimensional stability is poor (dry heat shrinkage is ±4 to ±5%, boiling water shrinkage is ±4 to ±5%), or the fabric surface is uneven and wrinkled and other defects. Limit the development of PBT fiber in the textile field. In order to break this situation,...
