Abstract
The invention discloses a disperse dye compound containing benzoate groups and application thereof. The structure of the disperse dye compound is shown in the following formula (I). The invention provides application of the dye in dyeing and printing hydrophobic fiber materials, particularly polyester/ammonia and other blended fabrics, and has excellent color fastness, particularly prominent washing fastness.
Description
Technical Field
The invention relates to a disperse dye compound and application thereof, in particular to a disperse dye compound containing benzoate groups and application thereof in printing and dyeing of hydrophobic fiber materials, particularly terylene and blended fabrics thereof.
Technical Field
In recent years, fabrics containing spandex are very popular internationally, and because of the soft hand feel, comfort and body beauty of the human body, such products are increasingly used. The spandex has very high elasticity, and the general product is not made of 100% polyurethane, and is usually made of composite yarns, namely spandex is taken as a core, and other fibers are taken as a skin layer to make the elastic fabric of the covering yarn, which is usually polyester/spandex blended fabric. Because the spandex has a special structure, the performance of the spandex is greatly different from that of polyester fibers, the spandex is easy to dye by the disperse dye, but desorption is easy to generate during washing, and various fastness of the product, especially washing color fastness, is reduced. Develop a kind of disperse dye with high washing staining fastness and meet the dyeing requirements of blended fabrics such as terylene/spandex and the like.
Disclosure of Invention
The invention aims to provide a disperse dye compound containing benzoate groups and application thereof, wherein the dye has excellent color fastness, especially prominent washing fastness (such as washing-resistant terylene color fastness, chinlon color fastness and acetate fiber color fastness) when a hydrophobic fiber material, especially a polyester/ammonia and other blended fabric is printed and dyed.
The technical scheme adopted by the invention is specifically described below.
