Embodiment 1

[0024] Select 100D-48f-common PET / soluble PET composite fiber 96% by weight, 30D spandex 4% by weight, use a 28G single-jersey knitting machine with a density of 46w / inch×84c / inch to form a blank, and then reduce the above blank , to obtain a blank containing multi-lobed special-shaped section PET yarns; finally, the obtained blank is subjected to post-dyeing treatment to obtain the deep-dyed elastic fabric of the present invention.

[0025] Among them, weight reduction-post-dyeing processing engineering: relaxation and scouring→intermediate setting→alkali weight reduction→disperse dyeing (including reduction cleaning)→hot air stenter setting

[0026] (1) Relaxation and scouring: The machine has 4 tanks in total, the temperatures of which are 40°C, 40°C, 60°C, and 90°C, the speed: 20m / min, and the residence time: 15-20 seconds.

[0027] (2) Intermediate shaping: temperature: 190 degrees, speed: 20m / min, overfeed: +55, the falling method is shaken, and the density is 45w / in×85c...

Embodiment 2

[0033] 60% by weight of 75D-48f-common PET / soluble PET composite fiber is used as warp yarn, 40% by weight of 50D-48f-PET / PTT yarn is used as weft yarn to form a blank, and then the above blank is reduced to obtain a multi-lobed special-shaped The white blank of cross-section PET yarn; finally, the white blank obtained is subjected to post-dyeing treatment to obtain the deep dyed elastic fabric of the present invention.

[0034] Among them, weight reduction-post-dyeing processing engineering: gray cloth setting → relaxation and scouring → alkali reduction → disperse dye dyeing (including reduction cleaning) → hot air stenter setting

[0035] (1) Gray cloth shaping: temperature 140°C, speed: 50m / min.

[0036] (2) Relaxation and scouring: the average temperature of the machine is 100°C, and the speed is 70m / min.

[0037] (3) Alkali weight reduction treatment: the weight reduction in the cylinder is 110°C×30min, and the final weight reduction rate reaches 15% (the fiber reaches ...

Embodiment 3

[0042] Select 55% by weight of 100D-24f-common PET / soluble PET composite fiber as warp yarn, and 45% by weight of 55D-24f-PBT yarn as weft yarn to form a blank, and then reduce the weight of the above-mentioned blank to obtain PET with multi-lobed special-shaped cross-section. The white blank of yarn; finally the white blank obtained is processed after dyeing to obtain the deep dyed elastic fabric of the present invention.

[0043] Among them, weight reduction-post-dyeing processing engineering: relaxation and scouring→alkali weight reduction→disperse dyeing (including reduction cleaning)→hot air stenter setting

[0044] (1) Relaxation and scouring: the average temperature of the machine is 100°C, and the speed is 70m / min.

[0045] (2) Alkali weight reduction treatment: in-cylinder weight reduction 110°C×30min, the final weight reduction rate reaches 19% (the fiber reaches the best fiber-opening state).

[0046] (3) Dyeing: Maximum temperature: 120°C×30min, heating rate: 1.0°...

Abstract

The invention discloses a deep-dyed elastic fabric and a production method thereof. The deep-dyed elastic fabric is a fabric comprising, by weight percentage, 89 to 95% of PET(polyethylene terephthalate) yarns with special multi-leaf-shaped cross sections and 5 to 11% spandex, or is a woven fabric comprising, by weight percentage, 50 to 70% of PET yarns with special multi-leaf-shaped cross sections and 30 to 50% of PBT (polybutylene terephthalate), PET / PTT (polytrimethylene terephthalate) or PET / PBT composite yarns, the diameter of monofilament of the PET yarns with special multi-leaf-shaped cross sections ranges from 10.0nm to 25.0nm, the cross section of the monofilament is provided with three to eight projections, and the average value of depth of each projection ranges from 3.0nm to 10.0nm. The deep-dyed elastic fabric is soft in touch, excellent in deep-dyed effect and higher in elastic restoring rate, and the production method thereof is simple.

Description

technical field [0001] The invention relates to an elastic fabric, in particular to a deep-dyed elastic fabric and a production method thereof. Background technique [0002] The PET yarn with multi-leaf special-shaped section is a new product with high quality, high performance and high technical content. Its monofilament linear density is smaller than that of conventional polyester fibers, and its specific surface area is larger. It is different from conventional polyester fibers in its excellent wearing properties, such as moisture absorption, quick-drying, breathable, soft, plump, fluffy and elegant. While the fine denier of the fiber can improve the breathability and moisture (gas) of the fabric, it also brings difficulties to its dyeing technology. Due to the particularity of PET yarn with multi-lobed special-shaped section, its dyeing rate, dyeing amount, dye promotion, color depth, level dyeing, color vividness and color fastness are not as good as conventional fiber...
