Abstract

The invention discloses a dyeing and finishing technology for a wool and recycled polyester blended fabric, comprising the following steps: 1) desizing: adding a 4-6 g/L chelated dispersing agent, a 1-2 g/L wax removal agent, an 8-9 g/L desizing enzyme and a 6-7 g/L refining agent; 2) bleaching: adding 3-4 g/L lead sulfate tribasic and 8-9 g/L hydrogen peroxide; 3) setting for 1 minute at 220 DEG C; 4) dyeing; 5) padding the dyed blended fabric in a treatment solution composed of a 30 g/l softening agent, an 80 g/L hairy feeling finishing agent and a 2-5 g/L fluffing agent; and 6) mechanical softening finishing, wherein wet pickup is 100%, and mechanical softening finishing time is 20 minutes. The dyeing and finishing technology for a wool and recycled polyester blended fabric provided by the invention can coordinate the dyeing conditions of wool and recycled polyester well so as to produce high-quality products.

Description

technical field [0001] The invention relates to the dyeing and finishing process of wool and regenerated polyester blended fabrics. Background technique [0002] Wool and recycled polyester fabrics have good moisture absorption and breathability properties, and also include the advantages of good elasticity of wool, high fiber density of polyester polymers, high wear resistance, high temperature resistance, and high strength. However, because polyester and wool fibers have different structures and different dyeing properties, dyeing often brings problems such as color registration difficulties and long process flow to enterprises. Contents of the invention [0003] The purpose of the present invention is to provide a dyeing and finishing process of wool and regenerated polyester blended fabric, which can coordinate the dyeing conditions of wool and regenerated polyester to produce high-quality products. [0004] In order to achieve the above object, the technical solution...
