High-color-fastness dyeing and finishing process for regenerated polyester fabric

Abstract

The invention relates to a high-color-fastness dyeing and finishing process for a regenerated polyester fabric, and belongs to the technical field of fabric dyeing and finishing. The process comprises the following steps of pretreating the fabric: burning off fine fluffs on the surface of the regenerated polyester fabric, and neatening the whole regenerated polyester fabric to prepare a primary polyester fabric; then performing bleaching and disinfecting: bleaching and disinfecting the primary polyester fabric prepared in the step 1, washing the primary polyester fabric with water, and drying the primary polyester fabric to obtain a secondary polyester fabric; then performing primary coloring; then performing sterilizing and deodorizing: soaking the primarily colored secondary polyester fabric in a sterilizing jar filled with sterilizing agent microcapsules for 20 minutes, adding a proper amount of natural plant perfume, finally taking out the secondary polyester fabric, washing the secondary polyester fabric with water, and drying the secondary polyester fabric; then performing secondary coloring: enabling the secondary polyester fabric to be subjected to microcapsule impact through a high-pressure dye carrier, and performing secondary coloring; and finally performing drying and setting. The product prepared through the process is high in color fastness, attractive in appearance, clean, sanitary, free of peculiar smell, relatively high in popularization value, high in economic value and suitable for being put into use.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a high color fastness dyeing and finishing process of regenerated polyester fabric. Background technique [0002] Dyeing and finishing, as the name implies, refers to printing and dyeing finishing, usually refers to the process of chemically treating fibers, yarns and fabrics. The whole process of textile production, the dyeing and finishing process usually includes pretreatment, dyeing, printing and finishing, the quality of dyeing and finishing has an important impact on the use value of textiles. [0003] In recent years, various anti-wrinkle, antibacterial, antistatic, fireproof, and waterproof new technologies have come out one after another, and the progress of dyeing and finishing technology is also obvious. Fabrics are processed through various technological means. Among them, recycled polyester fabrics are used as an environmentally friendly fabric. ...
