Problems solved by technology

Chinese patent CN106435833 uses polyethylene glycol diglycidyl ether as a cross-linking agent, and the cross-linking agent is added to the spinning solution for cross-linking reaction, and then chemically modified seaweed fibers are obtained, but the cross-linking reaction occurs before spinning , it will make the spinning process difficult to control and affect the spinning effect
[0010] There is no report on the use of tannic acid as a cross-linking agent for the preparation of washing-resistant seaweed fibers

Embodiment 1

[0049] (1) Preparation of spinning solution:

[0050] At room temperature, 30g of sodium alginate, 5g of tannic acid, and 1000g of water were used to prepare the spinning solution, and the concentration was 0.1035mol / L of NaHCO 3 The solution is used as a regulator to adjust the pH value of the spinning solution to 10;

[0051] (2) Preparation of washing-resistant seaweed fiber:

[0052] The spinning solution prepared in step (1) is mechanically stirred at a temperature of 45°C, defoamed and left to stand under vacuum conditions, and then the spinning solution is spun and extruded to a temperature of 50°C by a wet method or a dry spray wet method. , the concentration is that cross-linking reaction is carried out in 4.5wt% calcium chloride coagulation bath, coagulates through coagulation bath, makes the five-membered ring chelate that contains cross-linking network and the primary fiber of hydrogen bond cross-linking network structure, then through washing, Drawing and drying...

Abstract

The invention discloses a washing-resistant alginate fiber and a preparation method thereof, belongs to the field of textile chemical industry, and mainly solves the technical problem that the alginate fiber is poor in washing resistance. The natural cross-linking agent tannic acid is added into the spinning solution or coagulating bath of the alginate fiber, the alginate fiber is subjected to cross-linking treatment by selecting proper adding proportion and reaction conditions, the washing-resistant alginate fiber is prepared, and the actual durability of the alginate fiber is improved.

Description

technical field [0001] The invention belongs to the technical field of textile chemical industry, and in particular relates to a washing-resistant seaweed fiber and a preparation method thereof. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, "green clothing" will dominate the development of the world's textile and clothing field. Seaweed fiber is a fully biodegradable fiber prepared from sodium alginate as raw material, or sodium alginate compounded with other celluloses, and prepared by wet or dry spray wet spinning. Sodium alginate is a pure natural polysaccharide, which can be extracted from brown algae and other marine organisms. It is rich in resources and low in cost. At the same time, seaweed fiber has excellent water absorption, biocompatibility, and skin-friendly properties. It has broad application space in the field of high-end clothing, underwear fabrics and medical fields. [0003] However, curr...
