Embodiment 1

[0067] Exhaust dyeing of the red reactive dye composition of the present invention.

[0068] Weigh 1% by weight of the red reactive dye composition relative to the fiber and fully dissolve it in the chemical tank water. Under the condition of liquor ratio of 1:10, keep the cellulose fabric (the cotton knitted fabric of Shanghai Tiqiao Dyeing Co., Ltd.) circulating in the overflow, add the dye solution within 10 minutes, and keep the temperature at 35°C for 10 minutes Finally, add 30 g / l sodium sulfate, heat up to 60°C, add 20 g / l soda ash, keep warm for 45 minutes, then wash with water, soap, wash with water, and finally dry.

[0069] The composition of the red reactive dye composition used for above-mentioned exhaust dyeing is dye Ib:dye IIc=80:20 weight ratio.

[0070] Test data show that the red reactive dye composition of the present invention exhibits good color fastness. The dyed fabric has a vivid bright red hue.

[0071] Its staining fastness to washing is 4-5 grade...

Embodiment 2

[0073] Except that the composition of the red reactive dye composition used is dye Ia:dye IIa:dye IIIb=50:10:40 weight ratio, operate by the method identical with embodiment 1.

[0074] Test data show that the red reactive dye composition of the present invention exhibits good color fastness. The dyed fabric has a vivid bright red hue.

[0075] Its staining fastness to washing is 4-5 grades, its dry rubbing fastness is 4-5 grades, and its wet rubbing fastness is 3 grades. Measure the heat-sensitive performance of gained fabric by above-mentioned method, the result is listed in Table 1.

Embodiment 3

[0077] Except that the composition of the red reactive dye composition used is dye Ib:dye IIb:dye IIIa=50:10:40 weight ratio, operate by the method identical with embodiment 1.

[0078] Test data show that the red reactive dye composition of the present invention exhibits good color fastness. The dyed fabric has a vivid bright red hue.

[0079] Its staining fastness to washing is 4-5 grades, its dry rubbing fastness is 4-5 grades, and its wet rubbing fastness is 3 grades. Measure the heat-sensitive performance of gained fabric by above-mentioned method, the result is listed in Table 1.

Abstract

The invention provides a red reactive dye composition and a dying application thereof on fibre materials. The red reactive dye composition comprises one or more dyes with a general formula (1) and dyes with a general formula (2) and non-necessary dyes with a general formula (3), which are mixed in certain proportion. The red reactive dye composition has bright color and excellent dying fastness in various aspects; particularly, compared with other composition dyes, the thermal sensitivity resistance of the composition is significantly improved and enhanced.

Description

technical field [0001] The invention relates to a red reactive dye composition and its dyeing application on fiber materials. Background technique [0002] Excellent reactive dyes should have very good application properties. [0003] The development of red reactive dyes has always been a focus of current attention. [0004] Red reactive dyes not only require bright and bright colors, but also have good compatibility with reactive dyes of other colors. Dyeing with red reactive dyes must have good color fixing rate, improvement and various fastnesses, among which light fastness and heat resistance are particularly important. [0005] During the drying process of printing and dyeing production, the heat-sensitive properties of dyes cause the dyed fabrics to change color when exposed to heat, resulting in difficulty in color matching. [0006] WO-A-00 / 06652 discloses a series of disazo dyes from orange to blue starting from j-acid, including red dyes represented by the follo...
