Problems solved by technology

[0004] In recent years, in order to improve the additional performance of textiles in the export bills exported to Europe and the United States, special finishing operations such as heat setting are usually carried out on the fabrics. Due to the poor heat migration resistance of conventional disperse dyes, when dyeing polyester fabrics, During the finishing process of high-temperature tentering and setting, the dye migrates from the inside of the fiber through the fiber capillary to the surface of the fiber, causing the dye to accumulate on the surface of the fiber, staining other fabrics, and the color fastness to rubbing and washing.
Provide a kind of red disperse dye composition as document CN1640942A, CN1640943A etc., after finishing heat-setting, resistance to rubbing, color fastness to washing decline obviously

Embodiment 1

[0044] With the component A of 20 gram formula (I-1) compound, the component B of 30 gram formula (II-1) compound, the component C of 50 gram formula (III-1) compound and the dispersant MF of 180 gram, After adding 650 grams of water and blending, grinding, dispersing and drying, the finished product is obtained. The dye can provide the red color with excellent fastness properties to fabrics.

[0045]

Embodiment 2

[0047] With the component A of 25 gram formula (I-1) compound, the component B of 25 gram formula (II-1) compound, the component C of 50 gram formula (III-2) compound and the dispersant MF of 200 gram, After adding 800 grams of water and blending, grinding, dispersing and drying, the finished product is obtained. The dye can provide a red color with excellent fastness properties for fabrics.

[0048]

Embodiment 3～30

[0050] According to the method described in embodiment 1 or 2, the difference is to adopt the structure and weight of component A~component C in table 1, add 200 grams of auxiliary agents (dispersant MF is 150 grams, sodium lignosulfonate is 50 grams) gram), add 800 grams of water to blend and make slurry, grind and disperse, dry, and make finished product, this dyestuff can provide the red color that each fastness property of fabric is good.

Abstract

The invention discloses a disperse red dye composition, which is prepared from a component A, a component B and a component C, wherein the component A is selected from at least one of the following formula (I), the component B is selected from at least one of the following formula (II), and the component C is selected from at least one the following formula (III). The invention further provides adisperse red dye product, which contains the disperse red dye composition and additives. The invention also provides application of the disperse red dye product in the dyeing of hydrophobic fiber materials; the disperse red dye product has the characteristics of being good in dispersibility, high in strength, less in dye consumption, excellent in color fastness, and the like. The formula (I), theformula (II) and the formula (III) are described in the description.

Description

[0001] (1) Technical field [0002] The invention relates to a disperse red dye composition and a dye product, in particular to a disperse red dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] In recent years, in order to improve the additional performance of textiles in the export bills exported to Europe and the United States, special finishing operations such as heat setting are usually carried out on the fabrics. Due to the poor heat migration resistance of conventional disperse dyes, when dyeing polyester fabrics, During the finishing process of high-temperature tentering and setting, the dye migrates from the inside of the fiber to the surface of the fiber through the fiber capillary, causing the dye to accumulate on the surface of the fiber, contaminating other fabrics, and the color fastness to rubbing and washing is significantly reduced. Such as documents CN1640942A, CN1640943A e...
