Old-imitation processing method of polyamide-ester fabric

Abstract

The invention discloses an old-imitation processing method of polyamide-ester fabric. The whole processing process comprises the technological process as follows: fabric preparation, presetting, inkjet printing, baking, mechanical softening and finished product obtaining. Compared with a traditional old-imitation processing method of fabric, the method has the advantages that single-side coloring old-imitation finishing of the polyamide-ester fabric is realized, and meanwhile, the old-imitation effect of the fabric can be diversified and enriched through design of inkjet-printed patterns and pattern types. Besides, mechanical softening replaces traditional chemical softening, the old-imitation fabric is fluffy and thick in style, and a lot of chemical additives and energy are saved. The finally obtained old-imitation polyamide-ester fabric is gentle in color and rich and diversified in style, touches full and thick and has good visual and touch affinity.

Description

technical field [0001] The invention relates to a processing method for imitating old-fashioned polyamide-ester fabrics, in particular to a processing method for polyamide-ester fabrics which are spray-printed with paint ink and have rich old-fashioned styles. Background technique [0002] With the development of the times, people's material life and spiritual life have been greatly enriched, so the aesthetic taste and concept of textiles are undergoing a qualitative change. Personalized and diversified textiles are favored by people, and imitation textiles are highly praised by clothing consumers because of their unique comfort and affinity in color. [0003] CN101748602A discloses a method for processing knitted fabrics with cationic modification first, then dyeing and washing them to imitate old fabrics, the method achieves the effect of ring dyeing by dyeing after modification, and has a unique effect of imitating old times after washing , but a large amount of chemical...

Problems solved by technology

[0003] CN101748602A discloses a method for processing knitted fabrics with cationic modification first, then dyeing and washing them to imitate old fabrics, the method achieves the effect of ring dyeing by dyeing after modification, and has a unique effect of imitating old times after washing , but a large amount of chemicals and energy will be consumed in the process of modification, dyeing and washing, the process is relatively complicated, and pollutants will be generated during the process

In this invention, after being dyed with acid dyes or reactive dyes, strong oxidants are used for sand washing, softened and then dried. The distressed effect obtained by this method is relatively simple and the scope of application is narrow.

[0004] At present, most of the old-fashioned finishing is for cotton and wool fabrics, and it is rare to apply old-fashioned finishing to chemical fiber fabrics

Moreover, the traditional processing process consumes a large amount of auxiliaries, dyeing materials, water, electricity, steam, etc., and the processing technology is relatively complicated and the cost is high, so it does not meet the theme of contemporary energy saving, environmental protection and low carbon.

In addition, the obtained imitation fabrics are limited by the types of fabrics, and the imitation style is often relatively single, which cannot meet consumers' requirements for diversified clothing styles.

[0005] Although cotton fabrics have many advantages, pure cotton textiles have disadvantages that are difficult to overcome, including poor elasticity, no wrinkle resistance, easy shrinkage, no acid and mold resistance, etc., and the price of cotton is often higher than that of chemical fibers. Larger differentiation, so the quality stability of cotton textiles is lower than that of chemical fiber fabrics
