Example Embodiment

[0015] The present invention includes the extraction of sodium alginate, the preparation of sodium alginate spinning solution and wet spinning, and integrates and simplifies the process, eliminating the need for ethanol precipitation and drying in the extraction process of sodium alginate in the prior art. Dry crushing and redissolution during the preparation of sodium alginate spinning solution can not only reduce the discharge of waste liquid, but also reduce the degradation of sodium alginate. like figure 1 As shown in the schematic diagram of the process flow of the present invention, the preparation method of the seaweed fiber of the present invention specifically includes the following steps;

[0016] Step 1. Extraction of sodium alginate: Take 60g of kelp and place it in 1L of dilute hydrochloric acid (0.1mol / L), soak it at room temperature for 12h, wash off the surface extract with deionized water, add an appropriate amount of 3%Na 2 C0 3 Soak in the solution for 3 m...

Abstract

The invention discloses a preparation method of an alginate fiber. A sodium alginate water solution is prepared from sodium alginate extracted from kelp, and is filtered and debubbled to obtain a sodium alginate spinning solution; the sodium alginate spinning solution enters a spinning jet from a connecting pipe, and enters a coagulating bath through a spinning opening; and a sodium alginate filament is introduced into a washing bath after being stretched, and is dried by hot air to prepare the alginate fiber. The preparation technology is simple and convenient; energy is saved; consumption is reduced; and the product is good in hygroscopicity and softness.

Description

technical field [0001] The invention relates to the technical field of fiber preparation, in particular to a preparation method of seaweed fiber. Background technique [0002] The raw material of seaweed fiber comes from natural seaweed. The product has special functions such as good biocompatibility, degradable absorption, etc. It is a renewable resource and a good environment-friendly material. Alginate fiber is highly hygroscopic, [0003] Easy to remove, high oxygen permeability, and good compatibility with the human body, it is very suitable for medical surgical materials, so medical dressings, gauze, and bandages based on alginate fibers have been widely used. At present, the research on seaweed fiber mainly focuses on the development of functional seaweed fiber. In order to solve the unsatisfactory problems of existing seaweed fibers in terms of elasticity, strength and color, the development of blended seaweed fibers and composite seaweed fibers has become a resear...
