Abstract

The invention discloses a preparation method of a salt-resistant and detergent-resistant seaweed fiber; by introducing an auxiliary agent containing a borate radical, a finished product seaweed fiber is contacted and infiltrated with an auxiliary agent solution, appropriate raw materials, proportion and reaction conditions are selected, and thus the salt-resistant and detergent-resistant seaweed fiber is prepared. The preparation method solves the problems that the seaweed fiber and textiles thereof are not resistant to salts and detergents; the seaweed fiber after being modified by the borate radical and textiles thereof have good salt resistance and can withstand washing of alkaline detergents; the seaweed fiber modified by the auxiliary agent solution enables the swelling degree to be reduced to 39.8% after being soaked for 72 h in 30 DEG C normal saline, and enables the swelling degree to be reduced to 55.3% after being soaked for 24 h in a standard detergent; and the original appearance of the fiber is maintained, no obvious dissolution phenomenon generates, 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...
