Abstract

The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a processing technology of a high wash-and-wear warp and weft double-elastic fabric by adoptingspandex elastic yarns as warp yarns and purified cotton as weft yarns. Spandex elastic yarns are used as warp yarns, and weft yarns are made of purified cotton. The processing technology includes thefollowing steps: weaving, designing, singeing, desizing, scouring, oxygen bleaching, dry shaping, mercerizing, processing with liquid ammonia, whitening, wash and wear finishing, and softening. By adopting the processing technology, strength reduction of the fabric can be reduced, so that wash-and-wear performance of fabric appearance reaches 3.5 grades or above under the AATCC 124 method after water washing five times. During the finishing process, the fabric is naturally shrunk by a mechanical force, so that the elasticity of the fabric reaches 15% or above under the ASTM D3107-2011 method.The fabric is soft and comfortable to wear, and has high wash and wear performance, high resilience and the like.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a processing technology of warp-elastic and weft cotton high non-ironing warp and weft double-elastic fabric. Background technique [0002] Because elastic fabric has better elasticity, it is comfortable to wear and is favored by consumers. With the continuous appearance of new elastic fibers and the continuous improvement of people's living standards, people's demand for elastic fabrics is gradually increasing. Although elastic fabrics have many advantages, there are also deficiencies. At present, most elastic fabrics on the market are mainly cotton-wrapped spandex in the warp and weft direction. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a processing technology of warp-elastic and weft cotton high non-ironing warp and weft double-elastic fabrics. The flatne...
