Embodiment

[0084] The present invention will be described in detail with reference to the following examples, but the present invention is not limited to the examples. In the examples, "parts" and "%" refer to "parts by weight" and "% by weight", respectively.

[0085] [Examples 1-6 and Reference Examples 1-6]

[0086] The ingredient composition of each disperse dye composition of Examples 1-6 and the ingredient composition of each disperse dye composition of Reference Examples 1-6 are shown in Table 1-1 and Table 1-2 below, respectively. The respective dye components are blended, then the same amount of a dispersant as that of the dye components is added thereto, and the resultant is subjected to pulverization treatment to manufacture a disperse dye composition.

Embodiment 7

[0097] Add the yellow disperse dye composition of the reference example 1 of 0.42% o.w.f., the red disperse dye composition of the reference example 4 of 0.19% o.w.f. and the blue disperse dye composition of the embodiment 2 of 0.41% o.w.f.; The resultant was adjusted with sodium acetate so that its pH reached 4.5; 2.0% o.w.f. of Sunlife LPX-80 (manufactured by Nikka Chemical Co., Ltd., ultraviolet absorber) was added thereto to prepare a dyeing bath of 2000 parts in total; 100 parts of polyester fiber fleece fabric (using 0.3 denier yarn on the front side and 3 denier yarn on the back side) were immersed in a dyeing bath and dyed at 135°C for 30 minutes; then, at 80°C, the Water was added to a bath obtained by adding 6 parts of 45% sodium hydroxide, 6 parts of sulfoxylate and 3 parts of Sunmall RC-700 (manufactured by Nikka Chemical Co., Ltd., anionic surfactant) so that the total amount was 3000 parts , the dyed item was subjected to reduction washing for 10 minutes, and it ...

Embodiment 8

[0099] The same dyeing and post-treatment as in Example 7 were carried out, except that the yellow disperse dye composition of Reference Example 1 of 0.26% o.w.f., the red disperse dye composition of Reference Example 4 of 0.16% o.w.f. and 0.60% o.w.f. The blue disperse dye composition of Example 2, thereby providing a gray colored article. The light fastness and the color tone difference between the front side and the back side of the obtained dyed articles were measured by the method described later, and are described in Table 2.

Abstract

An object of the present invention is to provide a disperse dye composition that has the light fastness required of synthetic fiber materials for automotive interiors that are exposed to sunlight at high temperature and high humidity, and that has good blue, red, and yellow dyeability. This object is achieved by a mixed disperse dye composition containing a blue disperse dye composition having a specific composition ratio of five specific types of disperse dyes, and other specific yellow and / or red disperse dyes. The invention makes it possible to provide a disperse dye composition having not only high fastness of each color but light fastness with a favorable balance of the three primary colors, with the dye properties of each color equal during dyeing, and good dye color reproducibility, as well as by a dyeing method using this dye.

Description

technical field [0001] The invention relates to a disperse dye composition and a dyeing method using the composition. More particularly, the present invention relates to a disperse dye composition including a specific dye and a method of dyeing a hydrophobic fiber material using the disperse dye composition. Background technique [0002] Since the interior of the car reaches high temperature and high humidity and the synthetic fiber material used in the car interior material is exposed to sunlight for a longer period of time compared to other ordinary clothing fiber materials, the synthetic fiber material used in the car interior material needs to be durable. High temperature and high light fastness. In order to meet such demands, a method in which fibers are dyed using a dye having high light fastness is employed. However, if the light fastness of the yellow dye, red dye, and blue dye is unbalanced, only a part of the color fades due to long-term exposure, which tends to ...
