Problems solved by technology

Among them, temperature is one of the most important factors affecting the dyeing effect. Generally speaking, the higher the temperature, the higher the kinetic energy of the dye, and at the same time, due to the expansion of the fiber, the internal voids increase, which is convenient for adsorption and diffusion, thus speeding up the dyeing. However, if the temperature is too high When it is high, because the fiber gap is too large, the

Abstract

The invention relates to the technical field of printing and dyeing of fabric, in particular to a printing and dyeing process of polyester-cotton blended fabric. The printing and dyeing process specifically includes preprocessing, preliminary processing, dyeing and post-processing. The printing and dyeing process has the advantages that the printing and dyeing process is simple and easy to operate and even in dyeing, the dyed fabric is smooth and free of rags and burrs, the adhesive power of dye is enhanced greatly by ethanol fixation, fading after long-term soaking and rubbing is avoided, cloth wrinkles and shrinkage cannot be caused by the printing and dyeing, and breaking and pilling of cotton fibers and polyester fibers are avoided during the printing and dyeing.

Description

technical field [0001] The invention relates to the technical field of fabric printing and dyeing, in particular to a printing and dyeing process for polyester-cotton blended fabrics. Background technique [0002] The textile industry is my country's traditional pillar industry, including five parts: textile, printing and dyeing, chemical fiber, clothing and textile-specific equipment manufacturing. With the rapid development of the national economy, my country's printing and dyeing industry has also entered a period of rapid development, the level of equipment and technology has been significantly improved, and the production process and equipment have been continuously updated. The printing and dyeing process refers to the general term for the physical and chemical treatment of various textile materials (yarns, fabrics) in the production process, including the process of pre-treatment, dyeing, printing and post-finishing of textile materials, collectively referred to as th...
