Problems solved by technology

Wherein the existing printing and dyeing industry dyes cotton-polyester blended fabrics, usually adopts one-bath one-bath or one-bath multi-step method of disperse / reactive dyes for dyeing, and it dyes with respect to disperse / reactive dyes two-bath two-step method, although the operation steps obtain It must be simplified, but it will also lead to many problems, such as dye hydrolysis, uneven coloring, color flowering, color difference, low color fixation rate, etc.
[0004] And the existing disperse / reactive dye two-bath two-step dyeing method can avoid the problems of one-bath dyeing to a certain extent, but the disperse / reactive dye two-bath two-step dyeing method usually uses disperse dyes to dye polyester- Reduction cleaning-reactive dye dyeing cotton method, the entire dyeing process takes more than 10 hours, the production efficiency is low, the water, electricity, steam consumption is large, the sewage discharge is large, and because of the long wet processing time, it is easy to make the cloth surface Raising and affecting the fabric feel, reducing product quality and economic benefits of the enterprise

Abstract

The invention discloses a dyeing and finishing method for a cotton-Dacron blended fabric. The method is characterized by comprising the following steps: (S1) carrying out pretreatment, (S2) carrying out dyeing, (S3) carrying out softening and non-shrink, and (S4) sizing, wherein the pretreatment step comprises the steps of sequentially carrying out cold composting, oxygen bleaching and mercerization, and the dyeing step adopts a disperse dye and reactive dye dispersed bath-method for dyeing. In addition, according to the dyeing and finishing method for the cotton-Dacron blended fabric, disclosed by the invention, the method is simple, energy-saving and low-consumption, the dyeing is uniform, the color fastness is high, the color and luster are plump, and the hand feeling is soft.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular to a dyeing and finishing method of cotton-polyester blended fabrics. Background technique [0002] Cotton polyester blended fabric refers to a kind of fabric with only two components of polyester and cotton. This kind of fabric has both the moisture absorption, breathability and soft hand feeling of pure cotton fabric and the crispness, good drape and smooth appearance of polyester filament fabric. High-level features, therefore, comfortable to wear, crisp and smooth, easy to wash and dry quickly, washable and wearable, good wearing performance, and great market potential. [0003] Although with the advancement of dyeing and finishing technology and the development of new additives, the dyeing and finishing of cotton-polyester blended fabrics has made great progress. Wherein the existing printing and dyeing industry dyes cotton-polyester blended fabrics, usually adopt...
