Problems solved by technology

The traditional thermal fabrics, some are composite fabrics with wadding in the middle of the fabric, some are filmed fabrics, and some are fleece fabrics. These fabrics are made relatively thick, which affects comfort and appearance.
Although there are many elastic fabrics on the market, they are comfortable to wear and convenient to exercise, but they do not have a good thermal effect.

Embodiment 1

[0042] An elastic thermal fabric, the warp yarn adopts polybutylene terephthalate elastic yarn with 150D and crimp recovery rate of 40.7%, and the weft yarn adopts polybutylene terephthalate with 150D and crimp recovery rate of 40.7% Alcohol ester elastic yarn and 64N single yarn, of which 64N single yarn is viscose / acrylic blended yarn (60:40), arranged according to the arrangement ratio of 3:1, polybutylene terephthalate elastic yarn : The weight ratio of viscose: acrylic fiber is 80:12:8, weaving with double weave, the gray fabric cover factor is 3498, the gray fabric obtained is scouring→presetting→dyeing→softening→finishing and finalizing to finalize the finished product.

[0043] The main processing conditions are:

[0044] Pre-setting: setting temperature 180°C, speed 60m / min, wind speed 30Hz, set the door width according to the existing width, apply 5.0% overfeed rate, and drop the cloth by vibration.

[0045] Soft finishing: antistatic agent 10g / L, softener 6g / L, spe...

Embodiment 2

[0049] An elastic thermal fabric, the warp yarn adopts polybutylene terephthalate / polyethylene terephthalate bicomponent elastic yarn with 150D and crimp recovery rate of 50.2%, and the weft yarn adopts 150D and crimp recovery rate It is 50.2% polybutylene terephthalate / polyethylene terephthalate bicomponent elastic yarn and 64N double yarn, of which 64N double yarn is viscose / acrylic double-ply blended yarn (60 :40), arranged according to the arrangement ratio of 1:1, the weight ratio of polybutylene terephthalate / polyethylene terephthalate two-component elastic yarn: viscose: acrylic fiber is 61: 23:16, using weft double weave for weaving, the gray cloth cover factor is 2500, and the gray cloth obtained is scouring→presetting→dyeing→softening→finishing and shaping, and finally the finished product is obtained. Processing condition is with embodiment 1.

[0050] The resulting product has the advantages of good elasticity, comfortable wearing, and good warmth retention. The e...

Embodiment 3

[0052]An elastic thermal fabric, the warp yarn adopts 150D polybutylene terephthalate elastic yarn with a crimp recovery rate of 43.4%, and the weft yarn adopts 150D polybutylene terephthalate with a crimp recovery rate of 43.4% Elastic yarn and 34S double yarn, wherein the 34S double yarn is polyethylene terephthalate fiber / cotton double-ply blended yarn (65:35), arranged according to the arrangement ratio of 1:1, poly pairs Butylene phthalate elastic yarn: polyethylene terephthalate fiber: the weight ratio of cotton is 59: 27: 14, adopts weft double weave to weave, and gray cloth coverage factor is 3327, and gained gray cloth is again After gray fabric singeing→scouring→drying→presetting→dyeing→softening→finishing and setting, the finished product is finally obtained.

Abstract

The invention discloses an elastic warmth retention fabric and a production method thereof. The elastic warmth retention fabric is characterized in that more than 50 wt% yarns in warp and weft of fabric are elastic yarns with a crimp recovery rate between 35% and 55%; at least 20 wt% yarns are cotton yarns, hollow yarns, cotton / acrylic yarns or viscose / acrylic yarns; and the CLO value of the fabric is 0.6-1.2 m<2> DEG C / w, and the hygroscopicity is less than 1.5 seconds. The fabric produced by the method provided by the invention is good in elasticity, hard to distort, has no too thick and too heavy feeling, is good in warmth retention, simple in processing technique, and low in cost.

Description

technical field [0001] The invention relates to a textile, in particular to an elastic warm-keeping fabric and a production method thereof, belonging to the technical field of textiles. Background technique [0002] With the improvement of people's living standards, people's requirements for clothing functionality are getting higher and higher. Especially in the cold winter, the requirements for the fabric are higher, not only to improve the thermal effect of wearing, but also to be comfortable to wear without a sense of restraint. And traditional thermal fabrics, some are composite fabrics with wadding in the middle of the fabric, some are filmed fabrics, and some are fleece fabrics. These fabrics are made relatively thick, which affects comfort and appearance. Although there are many elastic fabrics on the market now, which have the characteristics of comfortable wearing and convenient movement, they do not have a good thermal insulation effect.
