Description
Technical Field
The invention belongs to the technical field of natural polymers and textiles, and particularly relates to a preparation method of biomass fibers for shielding ultraviolet rays.
Background
The incidence of skin diseases increases year by year in recent years, and research results show that ultraviolet rays are the most powerful cause of skin wrinkles, aging, laxity and black spots. Ultraviolet radiation causes the skin to generate a large number of free radicals, which results in a peroxidation of cell membranes, producing more melanin and spreading up the stratum corneum, resulting in black spots. Ultraviolet B (UVB) rays act on the surface layer of the skin, which causes denaturation of nucleic acids or proteins in skin cells, skin aging, and in severe cases, skin cancer. Ultraviolet a (uva) penetration into clothes and skin is deeper than UVB, causing pigmentation of melanin, resulting in skin aging. Therefore, the fabric with the ultraviolet shielding function is developed, and the health of the human body is effectively protected.
At present, there are two main methods for producing fabrics with ultraviolet shielding function at home and abroad: one is that ultraviolet screening agent is added in fiber production to produce ultraviolet resistant fiber, and then the ultraviolet resistant fiber is utilized to produce fabric, which has the function of screening ultraviolet; however, the method has high technical requirements, complex process and high production cost, is only suitable for the production of chemical fibers and is not suitable for natural fibers. Another one isThe method adopts nano TiO2The method is simple and easy to implement, but the nano ultraviolet screening agent is only attached to the surface of the fabric, is poor in washing resistance, is easy to abrade and wash off, loses the functionality of the fabric, and is reduced in comfort and hand feeling of the fabric. In a word, the ultraviolet shielding fabric produced according to the current method has poor ultraviolet shielding effect, poor wearability, poor air permeability, strong chemical fiber feeling and poor wearing comfort. Therefore, how to develop a biomass fiber which has good ultraviolet shielding performance, high mechanical strength, air permeability and skin affinity and is biodegradable is a key problem which needs to be solved urgently and is the development trend of the current functional textile materials.
Disclosure of Invention
The invention aims to provide a preparation method of biomass fiber for shielding ultraviolet rays, aiming at the defects of the performance and the preparation method of the existing ultraviolet-resistant fiber. The invention utilizes the reaction of hydroxyl in an agar structure with citric acid and ethylenediamine, introduces a thiazolopyridine carboxylic acid structure with ultraviolet absorption effect on agar, then utilizes a natural plant extract-tannin with rich sources as a cross-linking agent, improves the mechanical property of the biomass fiber based on the hydrogen bond bonding effect between phenolic hydroxyl in tannin molecules and hydroxyl in the agar, and simultaneously can further improve the ultraviolet absorption capacity of the biomass fiber due to the existence of a benzene ring structure in the tannin molecules. Compared with the existing production technology of the anti-ultraviolet fiber, the method has the advantages of simple process, easy operation, rich resources, low cost, no toxicity and high safety because the tannin and the agar are both derived from natural plants, and the prepared biomass fiber has the advantages of good ultraviolet shielding performance, good stability, high mechanical strength, air permeability, skin friendliness and biodegradability.

In the step (1), the concentration of the agar solution is 5wt% -20wt%, the molar ratio of the citric acid to the ethylenediamine is 1:0.5-1:2, the condensation reflux reaction temperature is 90-130 ℃, and the time is 6-12 h.
The concentration of the modified agar solution prepared in the step (2) is 3wt% -10wt%, and the mass ratio of the tannic acid to the modified agar solution is 1:30-1: 200.
The invention has the following remarkable advantages:
