Abstract

The invention discloses a high-fastness disperse red dye which comprises the components in parts by mass: 30-42 parts of a component A, 8-15 parts of a component B, 10-20 parts of a component C, 10-15parts of a component D, 8-20 parts of a component E and 5-12 parts of a component F. The high-fastness disperse red dye disclosed by the invention is prepared in proportion and is used for dyeing according to a conventional mode in the industry, so that a dyed fabric with plump hue, high light fastness, washing fastness and other excellent color fastness can be obtained.

Description

technical field [0001] The invention relates to the field of disperse dyes, in particular to a high-fastness disperse red dye. Background technique [0002] Disperse dyes are a kind of non-ionic dyes that dye hydrophobic fibers in a dispersed state under the action of dispersants in the initial stage of the dyeing process. Disperse dyes have a complete color spectrum, bright color, high color strength and good economy. [0003] Color fastness is also called color fastness and color fastness. It refers to the resistance of the color of textiles to various effects during processing and use. The fastness level is determined according to the discoloration of the sample and the staining of the undyed adjacent fabric. Textile color fastness test is a routine test item in the intrinsic quality test of textiles. Since disperse dyes do not contain water-soluble groups and have low molecular weight, they are uniformly dispersed in the dyeing solution by means of dispersants for dy...
