Embodiment 1
[0016] In Example 1, the fabric specifications are: the warp yarn is made of pure cotton 11.7tex, and the weft yarn is made of pure cotton 14.5tex for covering low-elastic web yarn 105D and spandex elastic yarn 70D. The mass ratio of the three is that pure cotton accounts for 92%, and the low-elastic web yarn Accounted for 5%, spandex stretch yarn accounted for 3%, 140*70*55 / 56 plain weave fabric, the process flow is as follows:
[0017] Yarn steaming: use high-temperature steaming in the yarn steaming machine to set the shape, stop steaming after 3 minutes of steaming, draw a vacuum, remove the air repeatedly 4 times, and then steam at 100°C for 20 minutes;
[0018] Weaving: speed 750rpm, tension 200kg, rear beam height 4cm depth 4cm, warp stop height 5mm, brown frame page number 4 pages, brown height 126mm, 126mm, 128mm, 128mm, opening angle during main spraying time is 270°;
[0031] In Example 2, the fabric specifications are: the warp yarn is made of pure cotton 11.7tex, and the weft yarn is made of pure cotton 14.5tex for covering low-elastic web yarn 105D and spandex elastic yarn 70D. The mass ratio of the three is that pure cotton accounts for 94%, and the low-elastic web yarn Accounted for 4%, spandex stretch yarn accounted for 2%, 150*90*57 / 58 twill fabric, the technological process is as follows:
[0032] Yarn steaming: use high-temperature steaming in the yarn steaming machine to set the shape, stop steaming after 2 minutes of steaming, draw a vacuum, remove the air repeatedly 4 times, and then steam at 100°C for 25 minutes;
[0033] Weaving: speed 700rpm, tension 200kg, rear beam height 4cm depth 4cm, warp stop height 4mm, brown frame page number 4 pages, brown height 128mm, 128mm, 128mm, 128mm, opening angle during main spraying time is 240°;

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.
