Problems solved by technology

However, general disperse dyes stain spandex and cotton heavily, which cannot meet the needs of customers
At present, there is a great demand for disperse blue in the market. The traditional C.I. disperse blue 284# has been widely used, especially because of its good washing fastness, it has been popularized by the general trend, but C.I. disperse blue 284# is only suitable for polyester fibers. , Polyester-cotton fiber, the advantage of washing fastness is not obvious

Embodiment 1-6

[0024] According to the ratio shown in Table 1, component A, component B, additives and an appropriate amount of water were mixed, ground, and spray-dried to obtain a composite disperse dye.

[0025] Table 1

[0026]

[0027] Use 0.1 g of the disperse dyes prepared in Examples 1-6, together with 10 g of polyester-spandex textile fibers and 99.9 g of water, adjust the pH of the dyeing bath to 4~5 with acetic acid, and heat up to 130° C. within 35 minutes. Keep warm for 30 minutes, cool to 80°C, take it out, and carry out post-treatment according to GB / T2394-2006 standard to obtain a blue textile material, and then carry out setting treatment at 190°C for 45 seconds. Measure its washing fastness to acetate, cotton, nylon, polyester, acrylic and wool according to AATCC61 2A method 95 degree standard.

Abstract

The invention discloses a disperse blue dye composition and a disperse blue dye and a preparation method and an application thereof. Based on the total weight of the disperse blue dye composition, the disperse blue dye composition comprises 60-90 percent of a component A and 10-40 percent of a component B, wherein the component A is the compound shown in the formula (I), and the component B is one or two of the compounds shown in the formula (II), wherein R1 is Cl or Br. The disperse blue dye comprises the disperse blue dye composition and auxiliary materials, and has good washing fastness and less staining to polyester/polyurethane cotton or blended fabrics thereof.

Description

technical field [0001] The present invention relates to a kind of disperse blue dye composition, disperse dye and preparation method thereof; A textile obtained by dyeing and / or printing the composition and a disperse blue dye, and a textile product made using the textile. The disperse blue dye is suitable for dyeing and printing of polyester fiber, especially suitable for dyeing and printing of blended fabrics such as polyester spandex and polyester cotton. Background technique [0002] With the rapid development of polyester-spandex polyester-cotton and other blended fabrics, people have higher and higher requirements for the application performance of dyes, and excellent fastness is the basic performance required by customers. However, general disperse dyes stain spandex and cotton heavily, which cannot meet the needs of customers. At present, there is a great demand for disperse blue in the market. The traditional C.I. disperse blue 284# has been widely used, especiall...
