Abstract

The invention discloses a method for coloring seaweed fibers with nano pigments. The method comprises the following steps: taking a certain amount of ultrafine water-based nano pigments and adding them to seaweed fiber spinning stock solution, stirring to disperse the pigment particles evenly, filtering and defoaming Afterwards, wet spinning is carried out at room temperature to prepare colored seaweed fibers, and the draft ratio of the fibers is 100-300%. The seaweed fiber prepared by the invention has uniform coloring, high washing and sunlight fastness, saves water resources and energy consumption, realizes clean production, and has good application prospects in the fields of clothing 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 ...
