Problems solved by technology

The traditional caustic soda mercerizing will also increase the luster of the fabric, and the fiber adsorption and chemical properties will be improved after treatment. Although the expansion effect of caustic soda is three times higher than that of liquid ammonia, due to the high viscosity of caustic soda, the penetration is not uniform, resulting in a weaker fabric feel. Hard, and the special structure of protein fibers makes it impossible to mercerize with caustic soda, which will seriously damage protein fibers

Abstract

A processing method of a cotton and silk interweaving fabrics comprises the following five steps: (1) singeing (2) desizing (3) liquid ammonia (4) sizing (5) preshrinking, and the step(3) comprises cloth inlet-prebaking-air cooling-padding the liquid ammonia-steaming - washing-roller drying-cropping, the cotton and silk fabrics which are processed by the liquid ammonia have the advantages of softand smooth feeling, no mightiness damage, no ironing and little washing shrinkage. Although the expansion effect of caustic soda is three times higher than the liquid ammonia, the caustic soda is high in viscosity and uneven in permeability, and owing to the good impregnability of the liquid ammonia, the treatment effect of the liquid ammonia and the mercerization of the caustic soda is different; cotton fiber is swelling, the warp direction and the weft direction of which are both very even after the liquid ammonia treatment. Although the liquid ammonia finish has the sense of the mercerizing, the liquid ammonia finish is different from the traditional mercerizing which leads the mightiness, the elasticity, the feeling of the cotton and silk fabrics to increase and improves the steady ofthe size without any corrosion and non homogeneity to the fiber which are caused by the caustic soda mercerizing.

Description

technical field [0001] The invention relates to a method for treating cotton and silk interwoven fabrics, in particular to a method for treating cotton and silk fabrics with liquid ammonia. Background technique [0002] With the development of high technology, the processing of textiles pays more and more attention to the technological content of its craft. Cotton and silk interwoven fabrics are favored because of their natural comfort and smooth luster, but the main defects of cotton and silk fabrics are poor wrinkle resistance and shrinkage after washing. This series of defects restricts the development of high-grade cotton and silk products. The so-called liquid ammonia is to cool the ammonia in the gaseous state at normal temperature to below -34°C to become liquid ammonia. The surface physical state of liquid ammonia is the same as that of water, and it is easy to flow, but its viscosity and surface tension are lower than water, and it has great penetration. It is easy...
