Problems solved by technology

Generally, vat dyes have excellent chlorine bleaching fastness, for example, red F3B, yellow G, bright green FFB, purple 2R, etc. have high chlorine bleaching fastness, but the application is more common, such as vat gray M dye, chlorine bleaching fastness It is difficult to meet the requirements of various indicators, especially for products for export, and in the dye

Abstract

The invention relates to a gray vat dye with a high fastness of resisting chlorine bleaching for tooling, comprising the following components: 18-22wt% of a dye monomer A, 4-8wt% of a dye monomer B, 6-10wt% of a dye monomer C, 62-68wt% of a dispersant and 0-2wt% of dust-proof oil. According to the national standard, chlorine bleaching resisting fastness of the gray vat dye can reach 4-5 levels, furthermore, the thermal pressure resisting fastness of the dye is 3-4 levels, the dry friction resisting fastness is 4-5 levels and the wet friction resisting fastness is 3-4 levels, so as to completely meet the performance of high-demand tooling series products.

Description

technical field [0001] The invention relates to a gray dye, in particular to a gray vat dye (vat gray W-M) with high chlorine bleaching fastness for tooling. Background technique [0002] Vat dyes are a class of high-grade dyes with many varieties, bright colors and excellent fastness. Due to their excellent light fastness, weather resistance, heat resistance, solvent resistance and wash resistance, vat dyes can be widely used in cotton, wool and silk. The printing and dyeing of cotton, linen, synthetic fibers and their blended fabrics and interwoven fabrics is a high-grade product in cotton dyes. [0003] In recent years, with the development of society, tooling products are facing higher requirements for chlorine bleaching fastness and heat pressing fastness. At the same time, the European and American markets also have high requirements for the color fastness of polyester-cotton tooling fabrics. , especially medical tooling fabrics require chlorine bleaching fastness AAT...
