Abstract

The invention discloses a preparation method of high-strength seaweed fiber. The method comprises the following operation steps that (1) hydroxy on sodium alginate monomers is oxidized into aldehyde groups by an oxidant; aldehyde alginate is prepared; (2) sodium alginate, the aldehyde alginate, polyethylenimine and water are uniformly mixed and are then prepared into a viscous mixture; (3) the viscous mixture prepared in the step (2) is extended into solidification liquid through spinning holes; solid calcium alginate fiber filaments are formed; the prepared product is sorted and is then prepared into the high-strength seaweed fiber. The preparation method of the high-strength seaweed fiber provided by the invention has the advantages that the operation is simple; the cost is low; the seaweed fiber is prepared; the original biocompatibility and far infrared radiation functions are maintained; the heat insulation effect is obvious, particularly, the strength is high; the physical property is stable; deformation cannot easily occur; the fracture phenomenon cannot easily occur.

Description

technical field [0001] The invention belongs to the technical field of fiber material preparation, and in particular relates to a preparation method of high-strength seaweed fiber. Background technique [0002] Seaweed fiber is a composite modified viscose fiber based on sodium alginate and fiber blending. It is a new type of fiber and is more environmentally friendly. After testing, seaweed fiber contains a variety of minerals, vitamins, proteins and marine bioactive substances. , can promote human circulation, antibacterial and anti-inflammatory effects, is a new type of fiber. Research on the spinning process of fibers from seaweed. To solve the technical difficulties in making seaweed fiber into textiles, a product with antibacterial and anti-inflammatory functions has been developed. Seaweed fiber made of high-end clothing or bedding has good antibacterial properties, which not only improves the grade of the product but also improves the quality of the product. Compet...
