Abstract

The invention discloses a disperse dye composition capable of improving strength and a preparing method thereof. The disperse dye composition comprises, by weight, 0.1-100 parts of C.I. disperse blue60, 0.1-50 parts of C.I. disperse green9, 0.1-50 parts of C.I. disperse blue354, 0.1-10 parts of C.I. disperse blue165 and 0.1-5 parts of disperse yellow. The preparing method of the disperse dye includes the following steps that 1, C.I. disperse blue60, C.I. disperse green9, C.I. disperse blue354, C.I. disperse blue165 and disperse yellow are taken according to the formula amount and mixed to obtain a mixed dye, wherein the disperse yellow is selected from C.I. disperse yellow211 and / or C.I. disperse yellow114; 2, water is added into the mixed dye obtained in the step 1, the weight dosage ratio of the mixed dye to the water is 1:(2-20), the mixture is mixed, and mixed slurry is obtained; 3, the mixed slurry obtained in the step 2 is sprayed and dried, and the disperse dye composition is obtained.

Description

technical field [0001] The invention relates to the field of printing and dyeing materials, in particular to a disperse dye composition and a preparation method thereof. Background technique [0002] Disperse dyes are a class of hydrophobic dyes with small molecules, simple structures, and no ionizable water-soluble groups. They mainly rely on the dispersion of dispersants to form a dispersed state in aqueous solution. Disperse dyes were developed for the dyeing of polyester fibers, and have flourished with the rapid increase in the application of polyester fibers. At present, the research and development of disperse dyes mainly focuses on its dye species, sublimation resistance, heat migration resistance, ironing resistance, light fastness, wet fastness, and adaptability to blended fabrics. [0003] The Chinese patent with the authorized announcement number CN102558908B and the authorized announcement date of August 13, 2014 discloses a composite high-strength disperse dye...
