Embodiment Construction

[0012] 1. Gray cloth:

[0013] The cotton yarn with a fineness of 14.6tex is used as the warp direction, and the Lycra formed by covering the 40D spandex yarn with a cotton yarn with a fineness of 14.6tex is used as the weft direction. After weaving, plain cotton spandex gray fabric is obtained.

[0014] Warp density of gray cloth: 362 threads / 10cm; weft density: 314 threads / 10cm, reed width: 175cm.

[0015] Second, finishing process:

[0016] 1. Singeing:

[0017] Adopt osthoff-senge singeing machine.

[0018] Speed: 130m / min; singeing method: cutting and burning; number of burners: 2; number of stages: 3-4.

[0019] 2. Desizing:

[0020] Adopt GOLLER desizing machine.

[0021] Vehicle speed: 80m / min; washing temperature: 90-95°C; amylase: 12g / l; stacking time: 30-35min; stacking temperature: 60°C.

[0022] 3. High temperature setting:

[0023] Using monforts setting machine.

[0024] Drying room speed: 30m / min; drying room temperature: 180°C; working fluid: clean wat...

Abstract

The invention provides an after-finishing method for a non-ironing finishing cotton spandex elastic fabric and relates to an after-finishing technology for fabrics. The after-finishing method comprises the following steps: singeing a gray fabric, desizing, setting at high temperature, mercerizing, performing non-ironing sizing, baking and preshrinking. According to the invention, the equipment does not need to be transformed; only the present process flows are adjusted and optimized, and the production technology is adopted for realizing the industrial production of the non-ironing finishing cotton spandex fabric and widening the application scope of the product; and the volume production of the non-ironing finishing cotton spandex fabric is realized in the manner of selecting the temperature for high-temperature sizing of the cotton spandex, optimizing the non-ironing technology and adjusting the production process flows according to the invention.

Description

technical field [0001] The invention relates to the post-finishing process of fabrics, in particular to the technical field of production of cotton spandex elastic non-ironing fabrics. Background technique [0002] Cotton spandex, commonly known as Lycra, is soft, comfortable, elastic, and not easily deformed. However, it is prone to wrinkles during wearing and washing, which directly affects the wearing effect of garments, so most garments are close-fitting clothing. [0003] To improve wrinkle resistance, conventional fabrics require a non-iron finish in wet conditions. Moreover, if cotton spandex is finished with conventional non-ironing, the size becomes smaller after wetting and the process cannot be implemented. Therefore, in the production of cotton spandex non-ironing fabrics, it is necessary to shape and stabilize the size of cotton spandex at high temperature first, and then do non-ironing finishing. However, after high-temperature setting and non-ironing finishi...
