Abstract

The invention discloses a preparation method of salt-resistant and detergent-resistant seaweed fiber, which is through introducing an auxiliary agent containing borate radicals, contacting and infiltrating the finished seaweed fiber with the auxiliary agent solution, and selecting suitable raw materials, ratios and reaction conditions , Prepared salt-resistant and detergent-resistant seaweed fibers. The preparation method of the present invention solves the problems of the seaweed fiber and its textiles that are not resistant to salt and detergent, and the seaweed fiber and its textiles modified by borate radicals have good salt resistance and can withstand the washing of alkaline detergents. The swelling degree of seaweed fiber modified by additive solution can be reduced to 39.8% after soaking in 30°C physiological saline for 72 hours, and the swelling degree can be reduced to 55.3% after soaking in standard detergent for 24 hours, and the fiber maintains its original shape. There is no obvious dissolution phenomenon, and at the same time, the self-flame-retardant performance of the seaweed fiber can be maintained.

Description

technical field [0001] The invention belongs to the technical field of textile chemical industry, and in particular relates to a preparation method of salt-resistant and detergent-resistant seaweed fiber. Background technique [0002] Alginate fiber is a biodegradable fiber made from sodium alginate by wet spinning. It has been widely used because of its good biodegradability, biocompatibility, excellent water absorption performance, and film-forming and fiber-forming properties. It has great potential in the application of high-end clothing, underwear fabrics and decorative textiles. [0003] At present, the seaweed fiber researched at home and abroad encounters Na + 、K + and H + In the solution of ions, these ions will exchange with the divalent cations in the seaweed fiber, which will cause the fiber to swell, destroy the complex cross-linking structure of the seaweed fiber, and cause the fiber to lose its fiber shape or even completely dissolve. This defect leads to t...
