Problems solved by technology

However, the imbalance among the respective lightfastnesses of the yellow dye, the red dye, and the blue dye causes only a part of the colored 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 characteristics (e.g. dyeing speed) between yellow, red and blue dyes can cause dyeing of synthetic fiber materials Differences in repeatability

Embodiment 3

[0086]In pure water, the yellow disperse dye composition of 0.607% o.w.f. (based on fiber weight), the red disperse dye composition of 0.204% o.w.f. and the blue disperse dye composition of 0.260% o.w.f. Acetic acid and sodium acetate were adjusted to pH 4.5, and 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 ...

Abstract

The present invention relates to a disperse dye composition containing a disperse dye and the like represented by formulas (1) through (4), and a method for dyeing a hydrophobic fiber material using the same. The present invention provides a disperse dye composition and a mixed disperse dye composition that not only have strong light fastness of each color, but also well-balanced light fastness between the three primary colors, and uniform dye properties during dyeing. The present invention also provides a method for dyeing using the disperse dye composition and the mixed disperse dye composition.

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 a disperse dye composition comprising a specific dye and a method of dyeing a hydrophobic fiber material using the dye composition. 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 much longer than for fiber materials used for ordinary clothing. In order to meet said requirements, fiber materials are dyed with dyes having high light fastness. However, the imbalance among the light fastness of each of the yellow dye, the red dye and the blue dye causes only a part of the colored dyes to fade due to long-term exposure to light, resulting in a color different from the original color. This cause...
