Problems solved by technology

However, the hand feeling of CVC fabrics processed by general dyeing and finishing is still relatively hard, poor in elasticity and ductility, and the style is monotonous. When people wear clothes made of this fabric, they will feel tight and stretchy. Generally, the printing and dyeing performance of CVC fabrics is poor, mainly due to the difference in properties of cotton and polyester fibers in CVC fabrics, making the pretreatment and dyeing and finishing process more complicated, especially the dyeing uniformity of cotton and polyester fibers is relatively difficult , and the technical requirements are relatively high, so the wearing performance of the CVC fabric after printing and dyeing is poor, and the aesthetic feeling is not enough.
Therefore, traditional CVC fabrics can no longer meet the needs of the market, and vigorously developing high-quality products is a key issue facing CVC fabrics and even clothing manufacturers.

Abstract

The invention discloses a dyeing and finishing method of a CVC (chief value of cotton) dyster fabric. The dyeing and finishing method comprises the following steps of S1, pretreatment; S2, dyeing; S3, post-finishing, wherein the pretreatment includes singeing, desizing, enzyme washing and mercerizing; the dyeing includes polyester dyeing, and cotton dyeing; the post-finishing includes tentering, pre-reduction, weft straightening, and shaping. The dyeing and finishing method of the CVC dyster fabric has the advantages that the method is simple, and the quality is stable; the hand feel of the fabric is soft, the dyeing cloth surface is full and uniform, the color is uniform, the texture is tight, and the elasticity is realized.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular to a dyeing and finishing method for CVC Dansberg fabrics. Background technique [0002] CVC fabric refers to a kind of fabric with only two components of polyester and cotton, and the content of cotton is greater than that of polyester. This kind of fabric has both the moisture absorption, breathability and soft hand feeling of pure cotton fabric and the crispness and flexibility of polyester filament fabric. It has the characteristics of good drapability and high flatness of appearance. Therefore, it is comfortable to wear, crisp and smooth, easy to wash and dry quickly, and can be washed and worn. It has good wearing performance and great market potential. [0003] Although with the advancement of printing and dyeing processing technology and the development of new additives, the dyeing and finishing of various CVC fabrics has undergone greater development. However,...
