Problems solved by technology

[0004] With the development of ultra-fine polyester fiber and the development of high-grade blended fabrics such as polyester / ammonia and polyester / cotton, the existing yellow to orange disperse dyes can no longer meet their dyeing needs during printing and dyeing, such as staining other fibers Serious, causing the overall color fastness of the fabric to decline, stains are not easy to remove and other problems, and in view of the EU REACH regulations to further reform the requirements of disperse dyes for polyester fibers, from environmental and ecological considerations, it is necessary to develop a new type of environmentally friendly dyes
ZL201711309007.1 and ZL201010212592.5 have developed dyes that can meet the above requirements, but there is still room for improvement

Embodiment 1

[0069] With the component A of 50 grams formula (I-1) and 40 grams formula (I-3), the component B of 10 grams formula (II-1), the dispersant MF of 150 grams, the lignosulfonic acid of 30 grams Sodium, after adding 650 grams of water and blending, grinding, dispersing and drying to obtain the finished product, the dye can provide yellow color with excellent fastness properties to polyester and its blended fabrics.

[0070]

Embodiment 2

[0072] Component A of 45 grams of formula (I-1), component B of 28 grams of formula (II-1), component C of 27 grams of formula (III-1), sodium lignosulfonate of 150 grams, add water After 600 grams of blending, grinding, dispersing and drying, the finished product can be obtained. The dye can provide yellow color with excellent fastness properties to polyester and its blended fabrics.

Abstract

The invention discloses a yellow-to-orange disperse dye composition and a dye product. The yellow-to-orange disperse dye composition comprises (by mass): 5-95% of an ingredient A and 5-95% of an ingredient B. The ingredient A is selected from at least one of compounds as shown in the formula (I); and the ingredient B is selected from at least one of compounds as shown in the formula (II). The yellow-to-orange disperse dye product contains the yellow-to-orange disperse dye composition and an auxiliary agent. The weight ratio of the auxiliary agent to the yellow-to-orange disperse dye composition is 0.2-5:1. When the yellow-to-orange disperse dye product is applied to dyeing of hydrophobic fiber materials, the color is plump, compatibleness is good, and each color fastness is excellent.

Description

[0001] (1) Technical field [0002] The invention relates to a yellow to orange dye composition and a dye product, in particular to a yellow to orange disperse dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] With the development of ultra-fine polyester fiber and the development of high-grade blended fabrics such as polyester / ammonia and polyester / cotton, the existing yellow to orange disperse dyes can no longer meet their dyeing needs during printing and dyeing, such as staining other fibers Serious, causing the overall color fastness of the fabric to decline, stains are not easy to remove and other problems, and in view of the EU REACH regulations to further reform the requirements of disperse dyes for polyester fibers, considering the environment and ecology, it is necessary to develop a new type of environmentally friendly dyes. ZL201711309007.1 and ZL201010212592.5 have developed dye...
