Embodiment 1

[0015] Technological process: seam turning, open weft shrinking, pre-shrinking, dehydration, pre-setting, alkali reduction, semi-finished product setting and rolling, printing, steaming, washing, dehydration and comfortable soft finishing.

[0016] Open-width weft shrinkage: The fabric enters the multi-stage weft-shrinkage box in open width through the thread opening and centering device, respectively at 65°C, 90°C, and 98°C, to prevent excessive shrinkage in the weft direction and uneven weft shrinkage to cause wrinkles. The speed of the machine is 35m / min. After the cloth is cooled by cold water, the cloth is squeezed and dropped to make the cloth body reach normal temperature. There will be no wrinkles when stacked in the cloth car. After weft shrinkage, the width of the fabric shrinks from 163cm to 126cm.

[0017] Preshrinking: carried out in a high temperature and high pressure rotary washing machine, whitening agent PS-1: 0.28%, NAOH (owf): 4%, refining agent CJ-108: 0.6g...

Abstract

The invention discloses a production process of polyester / polyurethane elastic printed chiffon, which comprises a pretreatment step, a printing step and a comfort softening step. The pretreatment step comprises weft shrinking in open width, presizing and alkali peeling. The process of weft shrinking in open width makes polyurethane preshrunk under the open width state of textile. The conditions of the presizing comprises a temperature of 200 DEG C, a speed of 55m / min, overfeed of 16%, an inlet fabric width of 102cm, and an outlet fabric width of 114cm. The conditions of the alkali peeling comprises the alkali concentration of an alkali rolling tank of 36g / L, expression of 90%, an alkali rolling temperature of 60 DEG C, a speed of 20m / min, and weight loss of 27-29%. With such method, the process of the invention can ensure the elasticity, crept effect, handle and comfort of polyester / polyurethane elastic printed chiffon.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a production process of polyester-spandex elastic chiffon printed cloth. Background technique [0002] Chiffon fabric is popular with consumers at home and abroad for its delicate surface effect, light and soft silk-like feel; elastic fabric is a popular trend in recent years, combining the two to develop polyester-spandex elastic chiffon fabric, Combined with the printing of various fine patterns, it becomes a promising new product. [0003] The existing polyester-spandex elastic chiffon printed cloth production process cannot effectively ensure the elasticity, Zou effect, feel and comfort of the polyester-spandex elastic chiffon printed cloth. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a production process of polyester-spandex elastic chiffon printed cloth, which can ensure the elasticity, Zou e...
