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

A kind of liquid ammonia treatment process of cotton wire union cloth
Technical field
The present invention relates to a kind of processing method of cotton wire union cloth, refer more particularly to a kind of liquid ammonia treatment process of staple fabric.
Background technology
Be accompanied by high-tech development, the scientific and technological content of its technology is more and more paid attention in the processing of textiles.The characteristics of cotton wire union cloth comfortable naturally and suitable sliding gloss because of it gain great popularity, but the major defect of staple fabric is crease-resistant ability, washes back shrink etc. that these a series of defectives have restricted the superior development of staple product.So-called liquefied ammonia is that the ammonia with gaseous state under the normal temperature is cooled to-34 ℃ of following liquefy ammonia, the surface physics state of liquefied ammonia is the same with water, be easy to flow, but its viscosity and surface tension are lower than water, has penetrability, be easy to be penetrated in the deep layer of cotton fiber tissue, cotton fiber is after liquefied ammonia soaks into, netted epitheca part is only shunk a little to some extent, the full expansion of biochemical reaction then takes place in the median fiber protein part after soaking, be accompanied by the expansion of fiber, the twisting stress of fibrous inside reduces or disappears, and makes the cotton fiber internal stress be tending towards homogeneous, smooth feeling between the fiber strengthens, fiber surface becomes smoothly, thereby makes cotton fiber show good flexibility, has fundamentally guaranteed facing anti-crease, shrink resistance.Also can increase the gloss of fabric behind traditional caustic soda mercerising, fiber absorption property after the processing and chemical property all can obtain to improve, although the expanded effect of caustic soda than liquefied ammonia Senior Three doubly, but because caustic soda viscosity height, permeate inhomogeneous, cause fabric feeling harder, and the special construction of protein fibre make it not carry out mercerising with caustic soda, can the major injury protein fibre.
