Printing and dyeing method of multicolor jacquard cotton cloth

Abstract

The invention discloses a printing and dyeing method of multicolor jacquard cotton cloth. The printing and dyeing method comprises the following steps of S1, preshrinking a liquid caustic soda; S2, carrying out reduction dyeing; S3, dewatering; S4, sizing and shaping; and S5, calendaring to obtain the multicolor jacquard cotton cloth. According to the printing and dyeing method of the multicolor jacquard cotton cloth, before reduction dyeing, the liquid caustic soda is adopted for preshrinking, so that the white jacquard cotton cloth is shrunk, the density of a jacquard part is further increased, the density of a non-jacquard part is further reduced, the multicolor state is shown after dyeing, the boundaries between different colors are clear, and the colors in the same area unit are consistent, so that the color of the jacquard parts can be effectively highlighted, the jacquard has a concave-convex feeling; after liquid caustic soda preshrinking is completed, the jacquard cotton clothis cleaned with clear water, and the usage amount of vat dye in the vat dyeing process can be effectively reduced; and in addition, the colors of the same area units at different positions of the jacquard cotton cloth printed and dyed through the method are consistent, and the quality of the jacquard cotton cloth can be effectively improved.

Description

technical field [0001] The invention relates to the field of fabric printing and dyeing, in particular to a method for printing and dyeing multi-color jacquard cotton cloth. Background technique [0002] In the printing and dyeing industry, the traditional printing and dyeing method for jacquard cotton is relatively mature, but the jacquard cotton printed and dyed by the existing method will have the following disadvantages: 1. The color of the jacquard cotton after printing and dyeing is relatively single, and the color of the jacquard and non-jacquard parts is close , it is impossible to realize the concave-convex feeling at the jacquard. 2. The color of the same area unit in different positions of the jacquard cotton cloth is inconsistent, and the color difference in the same area unit is relatively large. Due to the above-mentioned shortcoming, the product added value of existing jacquard cotton cloth is low, and the variety is low, it is difficult to make high-gloss jac...

Problems solved by technology

[0002] In the printing and dyeing industry, the traditional printing and dyeing method for jacquard cotton is relatively mature, but the jacquard cotton printed and dyed by the existing method will have the following disadvantages: 1. The color of the jacquard cotton after printing and dyeing is relatively single, and the color of the jacquard and non-jacquard parts is close , it is impossible to realize the unevenness of the jacquard. 2. The color of the same area unit in different positions of the jacquard cotton cloth is inconsistent, and the color difference in the same area unit is relatively large

Due to the above shortcomings, the existing jacquard cotton products have low added value and low variety, making it difficult to make high-gloss jacquard cotton fabrics enter the high-end market
