Dye for printing and dyeing cone yarns

Abstract

The invention relates to a dye for printing and dyeing cone yarns. The dye for printing and dyeing the cone yarns mainly consists of sodium lignin sulfonate, active pigment, polyethylene glycol, sodium dihydrogen phosphate, de-foaming agent, water and the like. The dye for printing and dyeing the cone yarns has the characteristics of strong coloring capability and high identical color ability, and the dyed yarns have good color fastness and long storage period and does not precipitate.

Description

technical field [0001] The invention relates to a dye solution for cheese printing and dyeing, which belongs to the technical field of textile dyeing auxiliaries. Background technique [0002] In the production process of the textile industry, post-dyeing finishing is an essential process, and yarn dyeing in packages is a brand-new dyeing process, which reduces the degradation and damage of fiber structures caused by piece dyeing, but the dyeing used in package dyeing The liquid performance plays a vital role in improving the hydrophilicity and adsorption of the fiber. The hydrophilicity and adsorption directly cause the problem of uneven dyeing of dyes or insufficient color fastness. Contents of the invention [0003] In order to obtain good same-color property in the dyeing process of yarn bobbins, the technical problem to be solved by the present invention is to provide a kind of strong coloring ability, high same-color property, after coloring, the yarn has good color ...
