Pure cotton textile dyeing and printing dye and production technology of same

Abstract

The invention discloses a pure cotton textile dyeing and printing dye and a production technology of the same. The pure cotton textile dyeing and printing dye is prepared by the following materials in percent by weight: 70%-80% of active black BMGB; 10%-20% of reactive brilliant blue BR and10%-20% of anhydrous sodium sulphate. The pure cotton textile dyeing and printing dye has the characteristics of being stable in color light, bright in color, high in dye-uptake, strong in fastness, excellent in washing resisting effect and environment-friendly and safe.

Description

technical field [0001] The invention relates to a printing dye used for dyeing pure cotton fabrics and a production process thereof. Background technique [0002] At present, there is only transfer printing of polyester cloth on the market, while transfer printing of high-grade pure cotton cloth is still blank. The main reason is that there is currently no ideal printing dye that can transfer the pattern on paper to cotton cloth, and there are disadvantages such as unstable shade, low dye uptake rate, unclear outline of printed pattern, and not bright color. Contents of the invention [0003] The object of the present invention is to provide a printing dye used for dyeing pure cotton fabrics and its production process, which has the characteristics of stable shade, bright color, high dye uptake, strong fastness, good washability, environmental protection and safety. [0004] In order to achieve the above object, technical scheme of the present invention is: [0005] A ki...
