Problems solved by technology

[0003] Currently on the market, there are products that can replace C.I. Disperse Yellow 23 with better effect. The most typical one is SE-3R Golden Yellow from Wenzhou Kaiyuan Leather Co., Ltd., but after the gradual use of manufacturers, it is found that SE-3R Golden Yellow is compatible with 2BLN Blue and 3B Red In the process of color matching, the compatibility is poor, such as head and tail difference in dyeing, overflow dyeing and even color flowering.

Abstract

The invention relates to a low-temperature environment-friendly disperse dye, which is especially suitable for printing and dyeing polyester materials and acetate fiber materials. The low-temperature environment-friendly disperse dye of the present invention is composed of the following components: dye monomer A with a weight fraction of 15-50%, dye monomer B with a weight fraction of 3-25%, and auxiliary agents in the balance. The low-temperature environment-friendly disperse dye preparation of the present invention has excellent fastness performance, high color giving power, bright shade, good level dyeing property and improvement property. 3B red and other disperse dyes are used for color matching, and the compatibility is excellent.

Description

(1) Technical field [0001] The invention relates to a low-temperature environment-friendly disperse dye, which is especially suitable for printing and dyeing polyester materials and acetate fiber materials. (2) Background technology [0002] There are many types of yellow disperse dyes used for dyeing polyester materials and cellulose acetate materials, among which C.I. Disperse Yellow 23 (old yellow RGFL) is used in a large amount, but it will be cracked under certain conditions to produce suspected carcinogenic substances, or Aromatic amines, which are harmful to humans, have been listed as banned disperse dyes by Germany and other EU countries. Therefore, at present, manufacturers urgently need to find a variety that can effectively replace the old yellow RGFL, and the yellow light must be close to it, and the performance must also be similar to it. The dyes form an effective compatibility, on the other hand, they must be environmentally friendly and can meet the needs o...
