Finishing method of warp cotton latitudinal double-core-spun non-ironing fabric

Abstract

The invention provides a finishing method of a warp cotton latitudinal double-core-spun non-ironing fabric. The finishing method is characterized in that warp yarns are pure cotton 11.7tex and weft yarns are formed by covering 5%-8% of low-elastic network yarns 105D and 2%-5% of spandex elastic yarns 70D with 90%-95% of pure cotton 14.5tex by mass. A process flow sequentially comprises the following steps: steaming yarns, weaving, turning cloth, singeing, desizing, scouring, bleaching, mercerizing, treating with liquid ammonia, carrying out wet crosslinking, piling, washing with water, tentering, pre-shrinking and checking. The yarns are subjected to high-temperature yarn steaming and part of stress of the spandex elastic yarns is released; in a dyeing and finishing process, machining and dry sizing are not carried out, and the problems that the fabric becomes yellow, the elasticity is low, edges are curled and the like can be improved; and after the fabric is washed with the water for 30 times under an AATCC 124 method through a wet crosslinking finishing technology, the appearance can reach more than or equal to 3.5 grades and the elasticity reaches more than or equal to 20% under an ASTM D3107-2011 method. The fabric treated by the method is soft and comfortable to wear, has moderate elasticity and good recovery, and has a good non-ironing effect.

Description

Technical field [0001] The invention provides a finishing method for warp, cotton and weft double-cored elastic non-iron fabrics, belonging to the technical field of textile printing and dyeing. Background technique [0002] Because stretch fabrics have good elasticity and are comfortable to wear, they are favored by consumers. With the continuous emergence of new stretch fibers and the continuous improvement of people's living standards, people's demand for stretch fabrics is gradually increasing. Although stretch fabrics have many advantages, they also have shortcomings. At present, most stretch fabrics on the market are mainly spandex. Because of the characteristics of the yarn, this type of fabric needs to be processed at high temperature to ensure the dimensional stability of the fabric. , While preventing fabric curling, fabrics are prone to yellowing, large loss of elasticity, and poor recovery during the finishing process, which have a great impact on production.

AI Technical Summary

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
