Problems solved by technology

If the bleaching effect is not good, the uniformity of whiteness on the surface of the fabric will be poor, the strength of the fabric will decrease, and the quality of the bamboo-cotton blended fabric will be seriously affected.
Not only that, the physical properties of bamboo fiber fabrics also changed greatly after being treated with traditional fabric antibacterial finishing agents.

Abstract

The invention discloses a bamboo fiber fabric dyeing and finishing process. The bamboo fiber fabric dyeing and finishing process comprises the following steps of: scouring and bleaching, namely scouring and bleaching a bamboo fiber fabric with a bamboo fiber fabric solution and drying; after drying, pre-shaping; pre-treating, namely desizing a pre-shaped textile; dyeing, namely immersing the fabric with 75wt% ethanol; adding the bamboo fiber fabric solution into an active dyestuff to prepare a dyeing solution; immersing the bamboo fiber fabric with the dyeing solution; putting the dyed bamboo fiber fabric into a reducing washing solution to be subjected to reduction and washing; washing the bamboo fiber fabric with clean water; after-finishing, namely putting the dyed textile into a hydrophilic amino silicon softening agent and padding; after padding, adding bamboo-vinegar liquor to prepare a finishing solution and then carrying out after-finishing; and tentering, namely drying the textile subjected to the after-finishing and tentering and shaping. By improving a scouring and bleaching method and a formula of the scouring and bleaching solution, strength damages of fibers are reduced; the pre-treatment has desizing and scouring effects and the strength of the bamboo fibers does not have relatively large loss; a dyeing process guarantees good dyeing effect and dyeing fastness and the surface of the finally produced textile is flat; the color and luster are uniform and the dyeing fastness of the dyestuff is high.

Description

technical field [0001] The invention relates to a bamboo fiber fabric dyeing and finishing process. Background technique [0002] Due to the particularity of bamboo fiber, if the dyeing and finishing process of cotton textiles is continued, the natural antibacterial properties of bamboo fiber will drop sharply. After pretreatment and dyeing, the antibacterial rate of the bamboo fiber blended fabric is less than 70%, and the antibacterial value is less than 1. If the boiling and bleaching effect is not good, the uniformity of whiteness on the surface of the fabric will be poor, the strength of the fabric will decrease, and the quality of the bamboo-cotton blended fabric will be seriously affected. Not only that, the physical properties of bamboo fiber fabrics also changed greatly after being treated with traditional fabric antibacterial finishing agents. [0003] Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the in...
