Problems solved by technology

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

Abstract

The invention relates to a dyeing and finishing process of a rayon fabric containing acrylic yarn, which includes dyeing and pretreatment of the primary woven rayon fabric, antistatic and anti-wrinkle finishing, and cooking and finalizing the primary woven rayon fabric Perform dye discharge printing, that is, immerse in the dyeing solution, the dyeing solution includes 1ml / L dyeing agent, 1ml / L chelating agent; heat up to 40-50°C, and steam for 20 minutes in a steamer with a steam pressure of 2kg ‑30min, the curve rises to 50‑60°C, keep warm for 10min, then add salt and soda ash. Fixative, followed by post-processing. The method of the invention obtains a strong three-dimensional effect of the discharge-printed dyed flower, the dye is firm, the moisture-permeable anti-ultraviolet effect reaches a satisfactory level, and the dyeing effect is good.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a dyeing and finishing process of rayon fabric containing acrylic yarn. 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. Th...
