Title:
METHOD FOR PREPARING SALT-RESISTANT AND DETERGENT-RESISTANT SEAWEED FIBER
Document Type and Number:
WIPO Patent Application WO/2016/165649
Kind Code:
A1
Abstract:
Disclosed is a method for preparing a salt-resistant and detergent-resistant seaweed fiber. By introducing an auxiliary agent containing a borate radical, a finished product seaweed fiber is made to be in contact with and infiltrated with an auxiliary agent solution, and appropriate raw materials, proportions and reaction conditions are selected, so as to prepare a salt-resistant and detergent-resistant seaweed fiber. The preparation method of the present invention solves the problem of the seaweed fiber and textiles thereof failing to be resistant to salts and detergents; the seaweed fiber after being modified by the borate radical as well as textiles thereof have good salt resistance and can withstand washing of alkaline detergents; the swelling degree of the seaweed fiber modified by the auxiliary agent solution can be reduced to 39.8% after the seaweed fiber is soaked for 72 h in 30ºC normal saline, and the swelling degree can be reduced to 55.3% after the seaweed fiber is soaked for 24 h in a standard detergent; and the original appearance of the fiber is maintained, no obvious dissolution phenomenon occurs, and at the same time, the self flame retardant performance of the seaweed fiber can be maintained.
