Problems solved by technology

But throughout the production of cotton knitwear, there are still many unsatisfactory aspects in the pre-treatment, such as the direct alkali shrinkage of the original embryo, which leads to uneven dyeing, which increases the pressure of production, and bleached fabrics suffer from stretching, yellowing, and reduced strength. Even brittleness and other problems, the sodium hypochlorite bleaching process of the fabric is too long, and the residual chlorine causes yellowing, switching to oxygen bleaching, the cost is relatively high, and there are problems such as hairy fabric surface and poor finish
In view of the existence of these problems, it is necessary to find the most reasonable pre-treatment process, so that the excellent characteristics of cotton fiber cannot be fully exerted

Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] Described in the present invention is a kind of anti-pilling acrylic fiber pretreatment process, see figure 1 . Described a kind of anti-pilling acrylic fiber pretreatment process comprises the steps:

[0019] (1) Fiber preparation: check fiber width, warp and weft density, check appearance defects, test fabric strength index, and also need to turn cloth and seam;

[0020] (2) Scouring: use a water-bath ratio of 1:6 to scorch the fibers, use steam heating, the heating temperature is 90°C, and steam scouring once or twice under normal pressure;

[0021] (3) Bleaching: put the fiber into the dyeing vat and bleach with hydrogen peroxide and...

Abstract

The invention discloses an anti-pilling acrylic woven fiber pretreatment process which includes the steps: (1) fiber preparation; (2) scouring; (3) bleaching; (4) dewatering; (5) fiber setting. The anti-pilling acrylic woven fiber pretreatment process has the advantages of high bleaching degree, stability, fine hand feeling, capability of removing natural impurities and the like.

Description

technical field [0001] The invention relates to a pretreatment process of anti-pilling acrylic fiber. Background technique [0002] Cotton fiber is a hydrophilic fiber. Because of its advantages such as air permeability and moisture permeability, the cotton fabric series products woven into it have always been loved by people because of their comfort. However, with the improvement of people's living standards, people have higher and higher requirements for fabrics. In addition to requiring comfort and functional requirements, fabrics are also required to have diversity and aesthetics. The perfect combination of functionality and aesthetics is the ultimate pursuit of the textile fabric industry. The main purpose of pretreatment is to remove cottonseed hulls, grease, wax, other artificial and natural impurities, and to provide a stable high intrinsic whiteness for bleached fabrics; in many cases, fabrics are also required to have high water absorption. All These must be obta...
