Classification of textile auxiliaries

Textile auxiliary refers to various chemicals needed in a series of processes from spinning, weaving to printing and dyeing, and organizing. It is mainly used to improve the quality of textile printing and dyeing, and collaborates to complete the requirements of dyeing or printing. , Flame retardant and other functional requirements, improve the added value and technical content of textiles. Textile aids can be divided into front treatment agents, dyeing and printed additives, post -finishing agents and other additives according to the different stages and functions of the dyeing process. The specific situation is as follows:

1 Pre -treatment agent

Remove the various impurities, slurry, oil agents, etc., improve the whiteness, hygroscopicness and size stability of the fabric, and meet the requirements of subsequent printing and dyeing processing. Generally including receding, refining, bleaching, silk and other additives.

2 dyeing and printing agent

Printing and dyeing refers to the physical or chemical combination of dyes or coatings and fibers, so that the fabrics of the front processing have a uniform color and good dyeing solidity and pattern processing process. The textile aids used in the processing process are collectively referred to as dyeing and printing agents. Generally, it includes uniform agents, color fixing agents, adhesives, thickening agents, paste, and cross -linked agents.

3 post -finishing agent

It refers to the processing process of improving and improving the quality of fabrics after the processing of fabric drift, dyeing and printing, and gives some special practical functions of textiles in the later collation process. Essence It includes waterproof oil -proof, flame -retardant, antibacterial mildew -proof mites, UV prevention, anti -wrinkle and anti -shrinkage, deepening increase, negative ions and other auxiliary agents.

4 Other additives

Special auxiliary products such as improving processing process and improving efficiency, energy saving, consumption reduction and emission reduction, and environmental protection. Including fabric optical agents, pH stabilizers, chelating dispersant, and one -meter cotton -to -pointer to restore the cleaning agent.
