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 kinetic energy of the dye particles is too large, but the part of the dyed fiber will be re-dissolved into the dye solution, which will affect the dyeing effect.
[0004] Blended fabrics are made of two or more fibers. Due to the inconsistent characteristics of each fiber, the printing and dyeing process is very demanding, otherwise it will cause problems such as uneven dyeing, fading, etc., resulting in a defective rate of the fabric. high

Embodiment 1

[0021] A printing and dyeing process for polyester-cotton blended fabrics specifically includes the following steps:

[0022] (1) Pretreatment: decoct the cloth with brine of saturated concentration at 60°C for 10 minutes, then cover the cloth with vinegar lees at 43°C and maintain the temperature for 24-36 hours, then wash the cloth with deionized water;

[0023] (2) Pretreatment: Immerse the cloth in a pretreatment tank with a pretreatment liquid, and control the bath ratio in the pretreatment tank to be 2:3 to 6;

[0024] (3) Dyeing: put the fabric in the water-soluble chitosan solution, put 0.1% methylene blue by weight of the fabric into the solution after 30 minutes, put cationic blue SD-BL 100% by weight of 0.2% into the solution after 2 hours (B-159), then the solution is heated to 53-61°C, the dye liquor of 40% of the fabric weight is put into the solution, then the temperature is lowered to 10°C at a rate of 1-2°C / min, and the fabric weight is put into the solution ...

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...
