Abstract

The invention discloses a dyeing and finishing technology of a crease resistant fiber blended knitted fabric. The technology comprises the following steps: sizing, desizing, refining, dyeing and soaping. The technology directly performs dyeing after desizing performed on fabric, improves the capacity of emulsifying and dispersing glue size by adding disperse dyes, a dye leveler and a buffering agent in dye liquor, and reduces the process time and energy consumption. By adopting the method, the dyeing process on the fabric is more reasonable, the production is clean and environment-friendly, the product quality is stable, the staining fastness of the fabric is increased to level 3 to 4 form level 1 to 2, and the cloth cover homochromatism is good.

Description

technical field [0001] The invention specifically relates to a dyeing and finishing process for crease-resistant fiber blended knitted fabrics. Background technique [0002] With the development of the times, the influence of scientific and technological progress on people's quality of life and cultural taste is increasing, and people's dressing concepts have undergone major changes. People spend more and more time going out and travel to different places. Therefore, Worsted fabrics suitable for travel have increasingly become a consumer demand for business people or travelers. [0003] When the fabric is desizing pre-treatment in the dyeing and finishing process, the concentration of powder chemical slurry in the auxiliary tank is very high. The phenomenon of staining the cloth surface. On the other hand, during the desizing treatment of spinning oil, the added degreasing aids usually cannot perform good wetting, penetration, blooming, dispersing, solubilizing, and washin...
