AI Technical Summary

Problems solved by technology

However, for the printing of medium and high-grade fiber fabrics, especially the imitation wax printing that requires rich and bright colors, there are still problems such as poor lifting power and unsatisfactory fastness to wet treatments such as washing resistance, chlorine resistance, friction resistance and perspiration resistance.

Embodiment 1

[0032] Component A shown in 70 grams of formula (I-1), component B shown in 30 grams of formula (II-1), 10 grams of sodium sulfate, 5 grams of sodium lignosulfonate are mixed in a mixing tank , or co-dissolved and then dried to obtain the reactive dyes of the present invention, which can provide bright red hues with excellent fastness properties to fabrics.

[0033]

Embodiment 2～13

[0035] According to the method described in Example 1, the difference is that the structure and weight ratio of component A and component B in Table 1 are adopted. In addition, the addition of sodium bicarbonate is 25 grams, and mixing is carried out, and this product can also be obtained. The reactive dye described in the invention can provide bright red hues with excellent fastness properties to fabrics.

Embodiment 14

[0038] Example 14: Dyeing

[0039] At 60° C., 100 grams of cotton fabric were added to the dyebath containing 1500 grams of 45 g / L sodium chloride and 2 grams of the reactive dyes obtained according to Examples 1-13. After dyeing at this temperature for 45 minutes, add 20g / L sodium carbonate solution and keep this temperature for another 45 minutes. Then, rinse the stain, soap with a non-ionic detergent for 15 minutes, rinse and dry. According to the methods determined in ISO 105-B02, ISO105-CO3, ISO 105×12 and ISO 105-E04, the color fastness to sunlight ≥ grade 5-6, the color fastness to washing ≥ grade 4-5, Color fastness to rubbing (wet rubbing) ≥ 4 grades, color fastness to perspiration ≥ 4 to 5 grades.

Abstract

The invention provides an active scarlet dye composition which mainly comprises one or a plurality of components A the structures of which are shown as a formula (I) and one or a plurality of components B the structures of which are shown as a formula (II). Based on the components A and the components B, the mass percent of the components A is 1 to 99 percent, and the mass percent of the components B is 1 to 99 percent; the advantages of the invention are mainly embodied as follows: compared with traditional dye with the same colour, the active scarlet dye shows favorable enhancement property and wet resistance, such as superior washing resistance, solarization resistance, friction resistance, perspiration resistance and colour fastness of chlorine water resistance; especially, the performance of the staining colour fastness of white cloth is outstanding; and moreover, the invention does not contain cancerogenic aromatic amine components and conforms to the requirement of environmental protection.

Description

(1) Technical field [0001] The invention relates to a reactive scarlet dye composition suitable for printing and dyeing nitrogen-containing or hydroxyl-containing fiber materials. (2) Background technology [0002] One of the important purposes of ecological dyeing with reactive dyes is to save energy, reduce emissions and improve product safety. With the rapid reduction of some traditional dyes, such as direct, vat and sulfur dyes, the application of reactive dyes has expanded rapidly, and many dark and fast-colored varieties are also widely dyed with reactive dyes. Due to the color fixing mechanism and characteristics of reactive dyes, the dyeing and printing of reactive dyes commonly used in the past, especially when printing and dyeing deep-colored varieties, the color fixing rate, improvement and color fastness of dyeing are not high, which not only brings dyeing efficiency and cost problems, and more prominently, serious ecological problems. In order to solve the abo...
