The use of coating printing has the advantages of simplicity in use and convenience in process, the printed fabric has the advantages of high light fastness and clear contour lines, and the stereoscopic impression of patterns with dark-color bottom and light-color florets can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of fabric production, in particular to a dyeing and finishing process for cotton fabrics. Background technique [0002] Modern textiles pursue the development of excellent regenerated natural plant fiber fabrics, improve and enhance the wearing function of natural plant fiber fabrics, and use them to meet the needs of the market, while rayon woven fabrics have special advantages and meet greater requirements for dyeing rayon fabrics. Market demand. The dyeing and finishing method of rayon fabrics in the prior art is not firm, especially the dyeing skills of medium and dark colors are insufficient, and the dyeing steps are complicated. Another example is that the effect of moisture permeability and anti-ultraviolet rays is not satisfactory. Consumers have higher requirements for the functionality, comfort, health, environmental protection and health care of clothing fabrics. The moisture permeability and ant...

Problems solved by technology

[0003] However, traditional clothing fabrics have single functions, low grades, poor comfort, and low added value, which cannot meet people's needs for clothing.

In addition, most of the existing dyeing and finishing methods of rayon fabrics use reactive dyes for direct printing, and the small floral pattern is acceptable in the market, but when it comes to patterns with dark backgrounds and light-colored small flowers, the printing effect is blurred and rough, with three-dimensional effect. Poor, the market reaction is very unsatisfactory
