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 to add disperse dyes under high temperature (135°C) and high pressure to dye under the condition of setting the shape. The resulting fabrics feel hard and the production cost is high, which cannot meet the modern life of people's comfort, convenience, leisure and sports. Way

Abstract

The invention relates to the technical field of fabric production and specifically relates to a dye liquor for low-temperature black polyester elastic knitted fabric and a dyeing technology. The dye liquor is prepared from dye and dye auxiliaries; the dye is cationic dye, including cationic red SD-GRL, cationic black AD-RN and cationic yellow SD-5GL; the dye auxiliaries include pure glacial aceticacid HAc, sodium acetate, a levelling and dispersing agent HTN, bath treasure HB226 and a chelate dispersing agent DM1016. According to the dye liquor for low-temperature black polyester elastic knitted fabric and dyeing technology provided by the invention, a polyester dyeing method is changed, so that original disperse dye is replaced by the cationic dye, a dyeing technology of dyeing before setting in a low-temperature condition is realized, the production cost including a large amount of steam is saved, and the factory benefits are increased; moreover, the obtained fabric has remarkable characteristics of soft handfeel and lasting elasticity.
