Embodiment 1

[0037] The structural formula of the polyvinylamine type macromolecular dye used in dyeing is:

[0038]

[0039] Among them, n 1 =50-60, n 2 =5-10, n=60-70

[0040] Dissolve 1g of the polyvinylamine-type macromolecular dye in 1000g of water, adjust the pH value to 8.5 with ammonia water, and mix evenly to obtain a dye liquor; then add 100g of calcium alginate fiber / silk fiber blended fabric into the dye liquor, and heat at 60°C Dyeing for 30min. After dyeing, take out the blended fabric, soak it in 4‰ neutral soap solution at 95°C for 10 minutes, and finally wash the seaweed fiber fully and dry it in the air.

Embodiment 2

[0042] The structural formula of the polyvinylamine type macromolecular dye used in dyeing is:

[0043]

[0044] Among them, n 1 =60-70,n 2 =10-15, n=70-80

[0045] Dissolve 1g of the polyvinylamine-type macromolecular dye in 2400g of water, adjust the pH value to 8.5 with ammonia water, and mix evenly to obtain a dye liquor; then add 80g of calcium alginate fiber / silk fiber blended fabric into the dye liquor, and heat Dyeing for 30min. After dyeing, take out the blended fabric, soak it in 4‰ neutral soap solution at 95°C for 10 minutes, and finally wash the blended fabric fully and dry it in the air.

Embodiment 3

[0047] The structural formula of the polyvinylamine type macromolecular dye used in dyeing is:

[0048]

[0049] Among them, n 1 =40-50, n 2 =15-20, n=60-70

[0050] Dissolve 1g of the polyvinylamine-type macromolecular dye in 2000g of water, use 10% sodium bicarbonate solution to adjust the pH value to 9, mix evenly to obtain a dye liquor; then add 50g of calcium alginate fiber / silk fiber blended fabric into the dye liquor , stained at 40°C for 40min. After dyeing, take out the blended fabric, soak it in 4‰ neutral soap solution at 95°C for 10 minutes, and finally wash the blended fabric fully and dry it in the air.

Abstract

The invention belongs to the technical field of fiber dyeing, and in particular relates to a method for dyeing calcium alginate fiber / silk fiber blended fabrics with macromolecular dyes containing polyvinylamine molecular chains. The present invention utilizes macromolecular dyes containing polyvinylamine molecular chains to form complex bonds with seaweed fibers under alkaline conditions, and at the same time polyvinylamine macromolecular dyes form hydrogen bonds and intermolecular interactions with silk fibers under alkaline conditions To achieve the dyeing of calcium alginate fiber / silk fiber blended fabrics with macromolecular dyes containing polyvinylamine molecular chains. The invention has high dye uptake rate, low dyeing temperature and short dyeing time, has good energy saving and emission reduction effects, can save a large amount of cost for enterprises, and has very good industrialization prospects.

Description

technical field [0001] The invention belongs to the technical field of fiber dyeing, and in particular relates to a method for dyeing calcium alginate fiber / silk fiber blended fabrics with macromolecular dyes containing polyvinylamine molecular chains. Background technique [0002] Silk fiber is a natural protein fiber that was first used by humans. This type of fiber has the characteristics of good compatibility with the human body, so it is very comfortable to wear. Silk fiber also has very good moisture absorption and perspiration wicking effects, so it is popular as a fabric for summer clothing. At the same time, silk fibers also have good warmth retention properties, and the home textiles such as silk quilts produced are light, thin and comfortable. In addition, the special luster, friction sound and texture of silk fiber have been widely recognized by the market, making it used as a high-grade textile fabric for various textiles. Blending silk fiber with other natur...
