Pure cotton bedspread cloth printing and dyeing technology

Abstract

The invention discloses a printing and dyeing process for pure cotton bed sheets, which is characterized in that it comprises the following steps: 1) Singeing: the distance between the singeing burner and the surface of the fabric is about 2 cm, and excessive hairiness on the surface of the fabric is removed to improve the quality of the fabric. Smoothness; 2) Descouring and bleaching: remove impurities on the fabric, make the fabric white, soft, and have good permeability, and provide qualified semi-finished products for dyeing, printing, and finishing. Process conditions: PH=8-10, temperature 100°C, time 60min, bath ratio 1:20; 3) Mercerizing: treatment with concentrated caustic soda solution to improve fabric properties; 4) Dyeing: physical or chemical combination of dyes and fibers, so that the entire textile has a certain color; 5 ) Printing: Refers to the printing of various dyes or pigments on fabrics with the help of the original paste as a carrier.

Description

technical field [0001] The invention relates to a printing and dyeing process for pure cotton bed sheets. Background technique [0002] At present, the printing and dyeing process of pure cotton bed sheets is complicated, and there is no unified standard, resulting in uneven printing and dyeing quality of pure cotton bed sheets produced. Many repeated processes also make the production efficiency low, increase the labor burden of workers, and at the same time make the market competitiveness of the products not tall. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a printing and dyeing process for pure cotton bed sheets, which is simple, eliminates many repetitive processes, and improves work efficiency. [0004] In order to achieve the above object, the present invention provides a printing and dyeing process for pure cotton bed sheets, which is characteri...
