Problems solved by technology

However, an imbalance between the respective light fastnesses of the yellow dye, the red dye, and the blue dye causes only a part of the color dyes to fade due to long-term exposure to light, resulting in a color different from the original color
This causes the following disadvantages: Color changes from the initial color appear more noticeable
[0004] Even when automotive interior materials are dyed with disperse dyes with the highest possible light fastnesses, unbalanced dyeing properties between yellow, red and blue dyes (e.g. step dyeing) cause dyeing of synthetic fiber materials Differences in repeatability

Embodiment 1

[0076] Embodiment 1: the manufacture of disperse dye composition

[0077] To 5.0% of the raw material powder represented by the formula (1), 1.6% of the raw material powder represented by the formula (2) and 26.0% of the raw material powder represented by the formula (3), a dispersant in an amount of 67.4% was added, and then It was pulverized to produce a yellowish disperse dye composition.

[0078] A dispersant in an amount of 65.0% was added to 7.5% of the raw material powder represented by formula (6) and 27.5% of the raw material powder represented by formula (7), which were then pulverized to produce a red-based disperse dye composition.

[0079] A dispersant in an amount of 75.4% was added to 22.5% of the raw material powder represented by formula (8) and 2.1% of the raw material powder represented by formula (9), which were then pulverized to produce a blue-based disperse dye composition.

Embodiment 2

[0080] Embodiment 2: the manufacture of disperse dye composition

[0081] To 6.0% of the raw material powder represented by the formula (1), 1.6% of the raw material powder represented by the formula (2), 12.0% of the raw material powder represented by the formula (4) and 4.9% of the raw material powder represented by the formula (5) The raw material powder was added with a dispersant in an amount of 75.5%, and then pulverized to produce a yellow-based disperse dye composition.

[0082] A dispersant in an amount of 65.0% was added to 7.5% of the raw material powder represented by formula (6) and 27.5% of the raw material powder represented by formula (7), which were then pulverized to produce a red-based disperse dye composition.

[0083] A dispersant in an amount of 75.4% was added to 22.5% of the raw material powder represented by formula (8) and 2.1% of the raw material powder represented by formula (9), which were then pulverized to produce a blue-based disperse dye compos...

Embodiment 3

[0085] In pure water, the yellow disperse dye composition of 0.570% o.w.f. in Example 1, the red disperse dye composition of 0.370% o.w.f. and the blue disperse dye composition of 0.400% o.w.f. are prepared with acetic acid and sodium acetate To pH 4.5, 2.0% o.w.f. of an ultraviolet absorber (SUNLIFE LPX-50, manufactured by Nicca Chemical Co., Ltd.) was added thereto to prepare 2000 parts of a dyeing bath. In a dyeing bath, soak 100 parts polyester fleece fabric (use 0.3 denier yarn on the front side and 3 denier yarn on the back side) and dye at 135°C for 30 minutes. The dyed article was then prepared in a bath consisting of 6 parts of 45% caustic soda, 6 parts of bisulfite, 3 parts of Sunmol RC-700 (anionic surfactant manufactured by Nicca Chemical Co., Ltd.) and adding water In a bath of a total amount of 3000 parts, reduction cleaning was performed at 80° C. for 10 minutes, washed with water, and then dried to produce a beige-dyed article. The dyed article thus obtained w...

Abstract

A disperse dye composition, which comprises specific dye(s), and a method for dyeing a hydrophobic fiber material using said disperse dye composition. Provided are a disperse dye composition and a mixed disperse dye composition, wherein a yellow disperse dye having a specific structure, a red disperse dye having a specific structure and a blue disperse dye having a specific structure are used so that not only high light fastness of each color is achieved but also well-balanced light fastness of the three primary colors is maintained and uniform dyeing characteristics are obtained in dyeing. Also provided is a dyeing method using the same.

Description

technical field [0001] The present invention relates to dye compositions and methods of dyeing using said dye compositions. More particularly, the present invention relates to yellow-based, red-based and blue-based disperse dye compositions comprising specific dyes, and methods of dyeing hydrophobic fiber materials using the dye compositions. Background technique [0002] For synthetic fiber materials used as automotive interior materials, high temperature resistance and light resistance are required due to the high temperature and high humidity in vehicles and the length of time exposed to sunlight far longer than that of fiber materials used for ordinary clothing sex. In order to meet said requirements, fiber materials are dyed with dyes having high light fastness. However, an imbalance among the respective light fastnesses of the yellow dye, the red dye, and the blue dye causes only a part of the color dyes to fade due to long-term exposure to light, resulting in a colo...
