Abstract

The invention discloses a blue-to-black dispersed dye composition and dye product. The blue-to-black dispersed dye composition is prepared from a component A and a component B, wherein the component Ais selected from one or more of compounds shown as a formula (I), the component B is selected from one or more of compounds shown as a formula (II), in the dispersed dye composition, the mass percentage content of the component A is 55-99%, and the mass percentage content of the component B is 1-45%. The blue-to-black dispersed dye composition can further include a component C, and the componentC is selected from following formulas (III) and / or (IV) and / or (V). The invention further provides the blue-to-black dispersed dye product, the blue-to-black dispersed dye product contains the blue-to-black dispersed dye composition and an addition agent, and the weight ratio of the addition agent to the dispersed dye composition is (0.2 to 5):1. The blue-to-black dispersed dye product is appliedto hydrophobic fibrous material printing and dyeing and has the characteristics of excellent color fastness, good dyeing economic efficiency and the like.

Description

[0001] (1) Technical field [0002] The invention relates to a blue to black disperse dye composition and dye products. [0003] (2) Background technology [0004] Elastic fabrics containing spandex are very popular in domestic and foreign markets. This kind of product has the advantages of high elasticity and excellent rebound performance, soft hand feeling, comfortable wearing, easy sweat absorption and no static electricity. Polyester / spandex elastic fabrics are mainly dyed with disperse dyes. Due to the high affinity and good dyeability of many disperse dyes to spandex, the contamination of spandex by disperse dyes is serious. During the fastness test, the disperse dyes stained on the spandex can easily migrate out of the fiber, affecting the wet fastness of polyester / spandex textiles. Many disperse dyes have good color fastness to rubbing, washing and light on polyester, but the fastness to spandex can only reach a moderate level, so that products with high color fastnes...
