Embodiment 40

[0068] Combine 45 grams of component A of formula (I-1), 52 grams of component B of formula (II-1), 3 grams of CI Disperse Orange 288, and 250 grams of sodium lignosulfonate. After machine grinding, dispersion and drying, the finished dye is obtained, which can provide polyester and its blended fabric with uniform and good fastness red.

[0069]

Embodiment 41

[0071] Mix 20 grams of component A of formula (I-1), 57 grams of formula (III-2), 23 grams of formula (IV-1), 5 grams of CI Disperse Red 82, and 200 grams of dispersant MF with water. , Use a grinder to grind, disperse and dry to obtain the finished dye, which can provide polyester and its blended fabric with uniform and good fastness red.

Embodiment 1

[0079] Take 2 grams of the disperse dye products prepared in Examples 1 to 39 respectively, add 500ml of water to prepare a dye solution, absorb 20ml of dye solution and mix with 80ml of water, adjust the pH of the dye bath to 4.5 with acetic acid, and then heat it to 60°C while putting it Put 2g polyester / spandex cloth for high-temperature and high-pressure dyeing, raise the temperature to 130°C within 35 minutes, keep the temperature for 30 minutes, and cool to 80°C for sampling. ISO 105-P01, ISO 105-X12, AATCC 61-2A were used to determine the color fastness to sublimation, color fastness to rubbing and color fastness to washing. The results are shown in Table 2 below:

Abstract

The invention discloses a disperse red dye composition and a dye product. The disperse red dye composition comprises the following components: 5-50 parts by mass of a component A and 50-95 parts by mass of a component B, wherein the component A is at least one selected from materials represented by a formula (I) shown in the description, and the component B is one or more selected from materials represented by a formula (II) and / or a formula (III) and / or a formula (IV) shown in the description; and the disperse red dye product comprises the disperse red dye composition and an auxiliary agent.The disperse red dye product prepared from the disperse red dye composition provided by the invention has the advantages of excellent washing fastness, sublimation fastness and rubbing fastness, goodbuild up property and a high color yield when used for dyeing of hydrophobic fiber materials such as polyester fibers and polyester / spandex fabrics, and fills the defect of poor build up property of ageneral high-fastness disperse dye.

Description

[0001] (1) Technical field [0002] The invention relates to a disperse red dye composition and dye products, in particular to a high fastness red disperse dye composition and dye products suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] Over the age of food and clothing, people are paying more and more attention to the improvement of quality of life. If the fastness of the purchased fabric is not good, problems such as staining and color matching will seriously affect the quality of life. In order to meet the needs of the market, various high-fastness disperse dyes are also appearing on the market. However, there is a general problem of single fastness performance, that is, it is difficult to achieve washing fastness, light fastness, sublimation fastness, and rubbing fastness. Excellent fastness and other fastnesses. In addition, common high-fastness disperse dyes often have problems such as poor improvement, low color yield,...
