Usage

General Description

Disperse Yellow 163 is a synthetic organic chemical used as a yellow dye in the textile and paper industries. It is a member of the azo compound family and is commonly used to color polyester and polyester-blend fabrics. Its bright yellow hue and good lightfastness make it a popular choice for coloring textiles, especially in outdoor applications. Disperse Yellow 163 is often applied to fabric using a sublimation process, where the dye is vaporized and then absorbed into the fibers of the material, resulting in a durable and long-lasting coloration. However, like many synthetic dyes, Disperse Yellow 163 can pose environmental and health risks, as well as potentially cause allergic reactions in some individuals. Therefore, proper handling and disposal procedures are necessary to minimize its impact on the environment and human health.

Disperse dye composition, and preparation method and application thereof

The invention relates to a disperse dye composition, and a preparation method and application thereof. The disperse dye composition comprises a component A formed by one or more of compounds shown in formula (1), a forbidden aromatic amine compound, chlorinated phenol, chlorobenzene, chlorotoluene, any auxiliary materials and other unavoidable impurities. According to the disperse dye composition, not only are various environment-protective indexes conform to the requirements of Oeko-Tex-Standard 100(2016), but also the total content of the forbidden aromatic amine compound in a dye composition chemical product for dyeing is 10ppm or lower, the total content of each chlorinated phenol is 0.5ppm or lower, and the total content of chlorobenzene and chlorotoluene (COCs) is 1ppm or lower. The sewage after the dyeing also can meet the environmental protection requirement; and meanwhile, the use is more convenient and secure. (Shown in description).

Clean preparation method for weakly alkaline arylamine azo disperse dye

The present invention provides a clean preparation method for weakly alkaline arylamine azo disperse dye. The method is characterized in that when a weakly alkaline arylamine diazonium double salt solid is coupled with a coupling component, the coupling component is pretreated to obtain a fine particle dispersion to be coupled with the weakly alkaline arylamine diazonium double salt; and the generated disperse dye is precipitated from the coupling system and is filtered and dried, thereby obtaining the weakly alkaline arylamine azo disperse dye. According to the preparation method provided by the present invention, by using a stable double salt structure of a diazonium salt, during the coupling, the process of adding acid for dissolution can be omitted; the coupling is performed at the normal temperature, and extra cooling is not required; and the method has a broad application prospect.
