Problems solved by technology

[0006] The existing document CN1696206A provides a disperse red dye with good coloring rate and strong sublimation fastness, but its washing fastness is average, and the dye B, namely C.I. Disperse Red 153, is yellowish red, and the compounded red is not bright enough; A kind of red disperse dye composition provided by CN103113759A, washing fastness is improved to a certain extent but there is still room for further improvement

Abstract

A red dispersed dye composition and dye product are provided. The composition comprises a component A, a component B and a component C. The component A is at least one selected from compounds shown as a formula (I). The component B is at least one selected from a compound shown as a formula (II-1) and a compound shown as a formula (II-2.) The component C is at least one selected from compounds shown as a formula (III). Based on the component A, the component B and the component C, the mass percentage of the component A is 20-90%, the mass percentage of the component B is 5-60% and the mass percentage of the component C is 1-40%. The red dispersed dye product comprises the composition and an auxiliary agent in a weight ratio of 0.2-5:1. The composition and the dye product have characteristics of bright color, good compatibility and excellent color fastness when being applied for dyeing a hydrophobic fibre material, and in particular, color fastness to washing is excellent.

Description

[0001] (1) Technical field [0002] The invention relates to a red dye composition and a dye product, in particular to a red disperse dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] With the continuous improvement of living standards, people have more and more functional requirements for clothing fabrics. The public expects more novel and dynamic clothing fabrics to appear. Polyester / spandex fabrics have high elasticity and excellent resilience properties. , soft to the touch, comfortable to wear, easy to absorb sweat and will not generate static electricity, etc. It is very popular in the domestic and foreign markets. The polyester / spandex fabric is mainly dyed with disperse dyes, but the existing disperse dyes contaminate the spandex seriously, resulting in wet The processing fastness such as soaping fastness, water color fastness and perspiration fastness is poor, which cannot meet th...
