Problems solved by technology

[0002] With the progress of the times and the further improvement of people's quality of life, people have higher and higher requirements for the comfort and convenience of clothing. Traditional knitted fabrics can no longer meet people's functional needs for fabrics.
We know that clothes lose their elasticity, they are easy to deform and loose, and lose their original pattern
The traditional dyeing process of knitted fabrics is under the condition of setting the shape, especially the bright color of red, which is more difficult to color. It must be dyed with disperse dyes at high temperature (135°C) and high pressure. The fabric feel after high temperature dyeing Hard, high production cost, can not meet people's modern lifestyle of comfort, convenience, leisure and sports

Abstract

The invention specifically relates to a low-temperature dye liquor and dyeing process for a bright rose-red polyester elastic knitted fabric, belonging to the technical field of fabric production. Thelow-temperature dye liquor for the bright rose-red polyester elastic knitted fabric comprises cationic dyes and dye auxiliaries, wherein the cationic dyes are composed of cationic red ED-5GL, cationic blue BG-ED and cationic red GRL-ED, and the dye auxiliaries are composed of pure glacial acetic acid HAc, sodium acetate, a dispersing and leveling agent ID, an anti-creasing agent HB226 and a chelating and dispersing agent DM1016. According to the invention, conventional dyeing methods for terylene are changed, original disperse dyes are changed into the cationic dyes, and unique composition ofraw materials and a unique dyeing curve are employed, so the dyeing process of dyeing at first and setting next at low temperature is realized, and the dyed fabric has a brilliant rose red color andgood color fastness, and the substantial characteristics of soft handle and permanent elasticity.
