Abstract

The invention discloses a method for coloring alginate fibers by a nano pigment. The method comprises the following steps: adding a certain quantity of superfine aqueous nano pigment into an alginate fiber spinning solution; agitating for uniformly dispersing pigment grains; filtering and defoaming; and carrying out wet-method spinning at room temperature to prepare colored alginate fibers, wherein the draw ratio of the fibers is 100%-300%. The alginate fibers prepared by the method are uniformly colored, is washable and has high sunlight fastness; water resources and energy consumption are saved and clean production is realized; the method for coloring the alginate fibers by the nano pigment has good application prospects in the fields of clothes and environmental protection.

Description

technical field [0001] The invention discloses a method for coloring seaweed fibers with nano pigments, and belongs to the fields of fine chemical industry and material science. technical background [0002] Seaweed fiber is a kind of natural, green and environmentally friendly fiber, which has the characteristics of high absorption, easy removal, high oxygen permeability, flame retardancy, radiation protection, antibacterial and deodorizing, biodegradability and compatibility. development and application value. Seaweed fiber comes from seaweed polysaccharides in seaweed, and its raw material sources are very rich. In recent years, with the increasing awareness of energy conservation and environmental protection, the research on the development of seaweed fiber with edible properties is gradually rising by using sodium alginate as raw material. s concern. In order to improve the dyeing effect of seaweed fiber, domestic scientific and technological workers have done a lot ...
