Abstract

The invention discloses a polyester blended fabric dyeing process, which comprises the following steps: (1) pretreating the polyester blended fabric first; (2) dipping the pretreated polyester blended fabric into the dyeing solution, first rapidly raising the temperature to 50 ℃, then slowly raise the temperature to 80~105℃, maintain the temperature at 80~105℃, dye for 30~60min, and finally cool down slowly to 60℃ and quickly cool down; (3) Finally, wash and dry the dyed polyester blended fabric Dry. Through the dyeing process provided by the invention, not only can the dyeing temperature of the polyester blended fabric be lowered to realize low-salt dyeing, but also the dyeing rate, level dyeing property and color fastness of the polyester blended fabric can be improved, and the softness of the fabric can also be improved at the same time , antistatic, anti-yellowing and bactericidal properties.

Description

technical field [0001] The invention relates to the technical field of textile fabric treatment, in particular to a polyester blended fabric dyeing process. Background technique [0002] At present, most of the fabrics commonly used in textile fabrics on the market are mainly cotton, polyester, nylon and regenerated cellulose fibers. Although these fabrics can basically meet people's needs, there are also some shortcomings. For example, polyester fabric has good heat resistance, but its hygroscopicity is poor and static electricity is serious, mainly because polyester fiber is a hydrophobic fiber with a tight structure, there is no specific dyeing group in the molecule, and it lacks hydrophilicity. The degree of expansion is low, which brings certain difficulties to dyeing. [0003] In recent years, with the continuous emergence of new fibers, multi-fiber composite fabrics are more widely used, such as polyester and wool, silk, acetate fiber, spandex and other fiber blended...
