Problems solved by technology

However, hydrolysis reaction inevitably occurs when reactive dyes are bonded to cellulose, resulting in more floating colors after dyeing, and the burden of soaping and washing is heavy. At the same time, the color fastness is low due to unclean removal of floating colors, which cannot meet the use requirements.

Abstract

The invention discloses a pure cotton fabric dyeing assistant and a preparation method thereof, relating to the technical field of dyeing assistants. The pure cotton fabric dyeing assistant is prepared from the following raw materials in parts by weight: 15-20 parts of attapulgite, 12-17 parts of charcoal ash, 10-15 parts of sodium carboxymethylcellulose, 10-15 parts of alkyl glycoside, 8-12 parts of rosin, 6-10 parts of rice bran wax, 6-10 parts of di-octadecyl dimethyl ammonium chloride, 5-8 parts of ethylenediaminetetraacetic acid disodium salt, 5-8 parts of nanometer bentonite, 4-6 parts of antibacterial agent, 3-5 parts of sodium citrate, 2-3 parts of rare earth, 2-3 parts of nanometer aluminium oxide, 1-2 parts of magnesium stearate, 7-13 parts of triethanolamine and 100-150 parts of water. The dyeing assistant can effectively reduce surface dyeing after dyeing, reduce the burden of soaping and washing, and improve the dye-uptake and colour fastness of an activated dye, fully plays a role in assisting dyeing, and thus improves the color and lustre, appearance quality and handfeel softness of a pure cotton fabric; besides, the use amount of the activated dye can be effectively reduced, and wastewater discharge and processing cost are reduced.

Description

Technical field: [0001] The invention relates to the technical field of dyeing aids, in particular to a dyeing aid for pure cotton fabrics and a preparation method thereof. Background technique: [0002] Pure cotton fabric is a textile made of cotton as raw material, which is interwoven vertically and horizontally by warp and weft yarns through a loom. There are many kinds of pure cotton fabrics with different designs and colors. According to the dyeing method, it can be divided into primary color cotton cloth, dyed cotton cloth, printed cotton cloth and yarn-dyed cotton cloth; it can also be divided into plain weave, twill cloth and forged cloth according to the fabric structure. Pure cotton fabric is loved by people because of its excellent hygroscopicity, heat resistance, alkali resistance and hygienic properties, and it is a very widely used fabric. [0003] Reactive dyes are an important class of dyes, which have the characteristics of bright color, complete color spe...
