Research on seaweed fiber in various countries

Algae fiber is spun from natural algae. Because the raw materials come from natural algae, the fiber has good biocompatibility, biodegradability and biocompatibility. SeaCell seaweed fiber produced by German company Alceru Schwarza is a fiber developed by taking advantage of carbohydrate, protein (amino acid), fat, cellulose and rich minerals contained in seaweed. The preparation method of this fiber is based on the production and manufacturing process of Lyocell fiber, which is made by adding ground seaweed powder or suspended matter into spinning solution for spinning. These algae mainly come from brown algae, red algae, green algae and blue algae, especially brown algae and red algae are the best raw materials for seaweed fibers.

The main value of seaweed fiber lies in seaweed composition, which can effectively improve moisture absorption. In the fiber, it can exert moisture absorption performance by contacting with the skin, and can actively release seaweed components, so that the wearer's skin can absorb vitamins and minerals released by seaweed. This kind of fiber contains major minerals such as calcium and magnesium, and vitamins include vitamins A, E and C, etc. The research on cosmetics shows that the minerals and vitamins A, E and C contained in seaweed have natural benefits to the skin and will not cause allergic reactions.

SeaCell fibers can be processed into short fibers or filaments of any length and fineness, and can also be blended with other fibers, such as natural fibers or man-made fibers. As long as 25% Seacell fiber is mixed into the fabric, you can feel the advantages of SeaCell. The final use of this fabric can be applied to shirts (adopted by Hanluo), home textiles, mattresses and so on. In addition, SeaCell Active is an antibacterial product. Adding silver and antibacterial components during spinning can slowly release silver ions and provide antibacterial function for a long time. This fabric can be designed into antibacterial sweatshirts, sheets, quilts, underwear and furniture. Qingdao University has disclosed a kind of chitosan grafted seaweed fiber and a patent for its preparation method and use. Because the surface of this fiber is coated with a certain amount of chitosan, it has good hygroscopicity and antibacterial property, and is non-toxic, harmless, safe and biodegradable. It has a good application prospect in the fields of medicine and environmental protection. As a new material for hemostasis treatment, it is especially suitable for making gauze as a wound dressing. Fiber strength:1.5d ~ 2.5d. Elongation at break: 4% ~ 10%. Fracture strength: 1.8g/d ~ 3. 1g/d

Seaweed carbon fiber and seaweed fiber are raw materials made of natural plants instead of minerals, and their wastes can be biodegradable and return to nature without polluting the environment. Seaweed carbon fiber has the effects of far infrared radiation and negative ions. Seaweed fiber has moisturizing and mineral calcium and magnesium components, and has a natural beauty effect on the skin. Driven by the continuous progress of biochemical technology, these fibers with heat preservation, health care and beauty functions will be favored and used by consumers if they can be combined with practical application and popular fashion, color and style design, and will be further promoted in line with the concept of health and environmental protection. I believe that in the near future, people's lives will be more closely related to this strange fiber.
