Embodiment 1

[0036] The printing paste for seaweed fiber fabric is made of the following raw materials in parts by weight:

[0037]

[0038] The structural formula of the highly water-soluble polycarboxylic acid dye DY-1 is:

[0039]

[0040] where: n 1 =20-30, n 2 =20-30, n=200-250.

[0041] The preparation method of printing paste for described seaweed fiber fabric is as follows:

[0042] Add urea to 5wt.% sodium alginate aqueous solution, mix well to obtain A solution; dissolve highly water-soluble polycarboxylic acid dye DY-1 in water, add 1wt.% ammonia solution to adjust the pH value to 6.5, and then add EDTA Calcium salt, stirred evenly to obtain solution B; mixing solution A and solution B, beating and homogenizing to obtain printing paste.

[0043] The printing paste is applied to the flat screen printing of the seaweed fiber fabric: the seaweed fiber fabric is printed with the printing paste, then the seaweed fiber fabric is baked at 85°C for 4 minutes, then steamed at 1...

Embodiment 2

[0045] The highly water-soluble polycarboxylic acid dye DY-1 in Example 1 is changed to the highly water-soluble polycarboxylic acid dye DY-2, and the rest of the steps are the same as in Example 1.

[0046] The structural formula of the highly water-soluble polycarboxylic acid dye DY-2 is:

[0047]

[0048] where: n 1 =40-50, n 2 =40-50, n=100-130.

Embodiment 3

[0050] The highly water-soluble polycarboxylic acid dye DY-1 in Example 1 is changed to the highly water-soluble polycarboxylic acid dye DY-3, and the rest of the steps are the same as in Example 1.

[0051] The structural formula of the highly water-soluble polycarboxylic acid dye DY-3 is:

[0052]

[0053] where: n 1 =40-50, n 2 =60-70, n=80-100.

Abstract

The invention belongs to the technical field of dyeing, and particularly relates to a printing paste for a seaweed fiber fabric, and a preparation method and an application thereof. 100 parts by weight of the printing paste for the seaweed fiber fabric are prepared from, by weight, 0.1-5 parts of highly water-soluble polycarboxylic dye, 2-5 parts of a cosolvent, 20-40 parts of an aqueous solutionof printing gum, 0.1-5 parts of a color fixer, 0.1-1 part of a pH adjuster, and the balance of water. The printing paste does not contain a large amount of inorganic salts, so the difficulty in the treatment of printing and dyeing wastewater is reduced; and the preparation method of the printing paste is simple, is easy to implement, and is easy to realize. The printing technology is a conventional printing process, so a device required by the invention is simple, and modification of an original printing device is avoided.

Description

technical field [0001] The invention belongs to the technical field of dyeing, and in particular relates to a printing paste for seaweed fiber fabrics and a preparation method and application thereof. Background technique [0002] Seaweed fiber is a new type of biodegradable synthetic fiber, which is prepared by extracting sodium alginate from natural seaweed, after purification and processing, and then by wet spinning process. This type of fiber not only has the characteristics of moisture absorption, softness, heat preservation and biocompatibility of traditional natural fibers, but also has excellent flame retardancy, antistatic and antibacterial properties, so it has a wide range of industrial application prospects. [0003] Since the invention of seaweed fiber in 1944, although there have been a lot of research and industrial development at home and abroad, its main use is still concentrated in the non-textile and clothing field of medical dressings, masks and other pro...
