Problems solved by technology

[0003] However, the color fastness to industrial washing of the fabrics treated by this process is not very good, high salt is not conducive to clean production, and the fastness is low. It is difficult for the pure cotton fabrics treated in this way to achieve more than 30 industrial washings without fading, and its color fastness In addition, the water and electricity consumption of this process is large, and the amount of additives is large, and the sewage discharge is large, which is not conducive to environmental protection, nor is it conducive to sewage treatment, and the resource consumption is large. Contrary to energy saving and consumption reduction
[0004] In addition, with the continuous improvement of people's living standards and the development of personalization, diversification and fashion for clothing, the products produced by traditional printing technology are single, simple in style and poor in printing effect, which cannot meet the current market needs.

Abstract

The invention discloses a process for printing and dyeing a pure cotton fabric. The process is characterized in that the repeated water-washing color fastness of the pure cotton fabric dyed by the process of the invention is greatly improved by selecting the components of a random dyeing liquid and a printing dye. The product printed and dyed by the process of the invention is good in dyeing effect so that the visual effect thereof is improved.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a printing and dyeing process for pure cotton fabrics. Background technique [0002] In the prior art, for the dyeing and finishing of pure cotton fabrics, the long-car continuous pad dyeing process is mostly used. The process steps are: turning over the seam, and then performing singeing, which requires one positive and one negative, followed by desizing, washing, and drying , mercerizing, then rolling, drying, and then sequentially carry out alkali color fixing, soaping, water washing, drying, tentering, finishing and packaging to obtain the product. [0003] However, the color fastness to industrial washing of the fabrics treated by this process is not very good, high salt is not conducive to clean production, and the fastness is low. It is difficult for the pure cotton fabrics treated in this way to achieve more than 30 industrial washings without fading, and its co...
