Finishing method of warp cotton and weft double core-spun elastic non-ironing fabric

Abstract

The present invention provides a finishing method for warp and weft double-core-spun elastic non-ironing fabrics, which is characterized in that: the warp yarn uses pure cotton 11.7tex, the weft yarn uses pure cotton 14.5tex to cover low-elastic network yarn 105D and spandex elastic yarn 70D, The mass ratio of the three is that pure cotton accounts for 90% to 95%, low elastic network yarn accounts for 5% to 8%, and spandex elastic yarn accounts for 2% to 5%. The technological process is steamed yarn, weaving, turning cloth, burning Wool, desizing, scouring, bleaching, mercerizing, liquid ammonia, moisture crosslinking, stacking, washing, tentering, pre-shrinking and inspection; the yarn is steamed by high-temperature steam to release part of the stress of the spandex elastic yarn, dyeing In the whole process, there is no processing and dry setting, which can improve the problems of fabric yellowing, low elasticity, curling, etc., and through the moisture cross-linking finishing technology, the appearance of the fabric after 30 times of washing under the AATCC 124 method can reach above 3.5, and the elasticity is in ASTM D3107 ‑2011 method can reach more than 20%. The fabric treated by the invention is soft and comfortable to wear, moderate in elasticity, good in recovery, and has excellent non-ironing effect.

Description

technical field [0001] The invention provides a finishing method for warp, cotton and weft double core-spun elastic non-ironing fabrics, which belongs to the technical field of textile printing and dyeing. 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 shortcomings. At present, most elastic fabrics on the market are mainly spandex. Due to the characteristics of the yarn, this type of fabric needs to be shaped at high temperature during processing to ensure the dimensional stability of the fabric. , At the same time prevent the fabric from curling, the fabric is prone to yellowing, large loss of elasticity, poor recovery and other problems during the finishing ...

Problems solved by technology

Although elastic fabrics have many advantages, there are also shortcomings. At present, most elastic fabrics on the market are mainly spandex. Due to the characteristics of the yarn, this type of fabric needs to be shaped at high temperature during processing to ensure the dimensional stability of the fabric. , at the same time prevent the fabric from curling, the fabric is prone to yellowing, large loss of elasticity, poor recovery and other problems during the finishing process, which has a great impact on production

[0003] At present, most elastic fabrics are made of pure cotton-wrapped spandex elastic yarn. Due to the existence of pure cotton fabrics, the fabric itself has poor non-ironing properties and serious wrinkles after washing, which cannot meet the needs of high-end consumers for elastic fabrics. At the same time, due to the existence of elastic fibers, many Elastic fibers are prone to breakage or elastic damage during non-ironing processing, which affects the non-ironing properties of fabrics. Therefore, elastic fabrics are rarely processed with non-ironing finishing, and non-ironing fabrics are generally poor in non-ironing properties. , the general non-ironing property is around level 3, it is difficult to meet people's demand for high-end elastic fabrics
