Problems solved by technology

[0003] Most of the dispersants currently used for disperse dyes are not special dispersants for disperse dyes, but broad-spectrum dispersants, which can be used in various fields such as pesticides, inks, papermaking, electroplating, coatings (ie dyes), and so on. When dispersing dyes, the dispersion effect is not satisfactory

Abstract

The invention discloses a dispersing aid for disperse dyes of cotton and linen fabrics, and relates to the technical field of preparation of disperse dyes. The dispersing aid is prepared from the following raw materials in parts by weight: 28 to 36 parts of sodium carboxymethylcellulose, 11 to 16 parts of hexamethylphosphoramide, 6 to 10 parts of potassium sulfate, 12 to 15 parts of magnesium aluminum silicate, 9 to 12 parts of nano titanium dioxide, 10 to 20 parts of cellulose acetate nitrate, 8 to 12 parts of calcium chloride, 15 to 25 parts of ethylenediamine tetraacetic acid disodium salt,16 to 22 parts of bis[2-(2-butoxyethoxy)ethyl] adipate, 6 to 10 parts of diisobutylaluminum hydride, 12 to 15 parts of dodecyl dimethyl betaine. The dispersing aid contains the sodium carboxymethylcellulose, the hexamethylphosphoramide and the ethylenediamine tetraacetic acid disodium salt, so that the dispersing aid is particularly suitable for disperse dyes for fabrics of cotton and linen materials, the magnesium aluminum silicate can increase homogeneity of the disperse dyes, the nano titanium dioxide can improve the wettability of the disperse dyes on dying objects, and the cellulose acetate nitrate improves the stability of the disperse dyes to water.

Description

Technical field: [0001] The invention relates to the technical field of preparation of disperse dyes, in particular to a dispersing aid for disperse dyes of cotton and linen fiber fabrics. Background technique: [0002] Disperse dyes are a class of dyes with relatively small molecules and no water-soluble groups in their structure. It must be dyed with the aid of a dispersant to disperse the dye evenly in the dyeing solution in order to dye fibers such as polyester. The main use of disperse dyes is to dye polyester fibers (polyester) acetate fibers (diacetate, triacetate) and polyamide fibers (nylon) in chemical fibers, and there are also a small amount of applications for polyacrylonitrile (acrylic fibers). Chemical fiber textile products printed and dyed with disperse dyes are bright in color, excellent in washing fastness, and widely used. Because it is insoluble in water, it has no dyeing ability to cotton, linen, wool, and silk in natural fibers, and it hardly stains ...
