Abstract
The invention relates to a fiber and a preparation method technology thereof, in particular to a hyaluronic acid fiber and a preparation method and application thereof. The invention provides a hyaluronic acid fiber, which comprises, by weight, 4-12 parts of hyaluronic acid slurry and 88-96 parts of spinning stock solution. The hyaluronic acid serous fluid comprises sodium hyaluronate, deionized water and an auxiliary agent in a weight ratio of (0.8-2): (94.6-97.8): (0.8-3.4). The raw materials of the spinning solution comprise wool fiber, cotton fiber and ionic liquid, wherein the weight ratio of the wool fiber to the cotton fiber to the ionic liquid is 50: 15: 35. and stirring and mixing the hyaluronic acid slurry and the spinning stock solution for 40-60 minutes to obtain a mixed spinning solution, and then preparing the hyaluronic acid fiber according to a wet spinning process. The fiber prepared by the invention contains hyaluronic acid, and the hyaluronic acid is easy to basically not fall off after being washed for many times.
Description
Technical Field
The invention relates to a fiber and a preparation method technology thereof, in particular to a hyaluronic acid fiber and a preparation method and application thereof.
Background
In recent years, with the change of life style and the improvement of living standard of people, the textile industry is changing according to the needs of people. Comfortable heat preservation, health care, antibiosis, beauty and face nourishing become new requirements of people for textiles.
Hyaluronic acid is also called hyaluronic acid, the basic structure of hyaluronic acid is a large polysaccharide consisting of two disaccharide units, namely D-glucuronic acid and N-acetylglucosamine, commercial hyaluronic acid generally refers to sodium salt thereof, namely sodium hyaluronate, but is still called hyaluronic acid in a habitual way, and an aqueous solution of sodium hyaluronate has excellent moisture retention, viscoelasticity and lubricity, is an ideal moisture retention factor, can play a unique role in protecting skin when being used in cosmetics, and is also applied to fabric through related research reports, so that when people wear clothes made of the fabric, the hyaluronic acid has a beneficial effect on human skin. At present, the research on the application of hyaluronic acid to the fabric mainly comprises two methods: (1) soaking the fiber in a solution prepared from hyaluronic acid, draining to obtain modified fiber, and making fabric by using the modified fiber; (2) and soaking the fabric in hyaluronic acid finishing liquid, and then fixing hyaluronic acid on the fabric through crosslinking and curing.
The fiber is mainly used for providing the warm-keeping and moisture-keeping fiber aiming at the northern cold and dry climate environment, and the fabric prepared from the fiber belongs to warm down fabrics, and has the warm-keeping performance and excellent antibacterial and moisture-keeping performance. Although the fabric with the moisturizing performance prepared by using the hyaluronic acid is available, the moisturizing effect is not long enough, or the hyaluronic acid is easy to fall off after the fabric is washed for many times.
Disclosure of Invention
In order to solve the above technical problems, a first aspect of the present invention provides a hyaluronic acid fiber, the raw materials of which include hyaluronic acid slurry and spinning dope.
As a preferred technical scheme of the invention, the raw materials of the hyaluronic acid fiber comprise, by weight, 4-12 parts of hyaluronic acid slurry and 88-96 parts of spinning stock solution.
As a preferred technical scheme of the invention, the hyaluronic acid serous fluid comprises the following raw materials in percentage by weight (0.8-2): (94.6-97.8): (0.8-3.4).
According to a preferable technical scheme of the invention, the raw materials of the spinning solution comprise wool fibers, cotton fibers and ionic liquid, wherein the weight ratio of the wool fibers to the cotton fibers to the ionic liquid is 50: 15: 35;
