Haizao -- something you don't know!

Seaweed can also be made into clothes, which are more comfortable than cotton cloth. In appearance, there is no big difference except that it is smoother than ordinary cotton. The difference is that it is made of a variety of seaweeds, such as kelp, kelp, fuchsia, kelp and sargassum. Common brown algae can almost be used as raw materials for seaweed fibers, and seaweed fiber functional fabrics woven from seaweed fibers are a highlight of functional clothing fabrics!

How does seaweed become fiber?

After sodium alginate is dissolved in water to prepare spinning solution, alginate fiber is prepared by wet spinning. From a chemical point of view, the forming process of alginate fiber is a process in which water-soluble sodium alginate is transformed into water-insoluble calcium alginate. Algae are dissolved in a closed tank in a special way. The dissolved raw materials enter the rinsing tank through multiple processes such as filtering, extraction, stretching, etc. There is a nozzle like device at the source of the rinsing tank. After the nozzle, tens of thousands of fibers will be formed. These fibers will be reprocessed and cooled to form seaweed fibers.

What are the functions of seaweed fiber?

First of all, seaweed fiber is a flame retardant fiber, which has flame retardancy. Under the burning of the flame, only the contact part with the flame blackens and will not burn, which is the carbonization reaction of the seaweed fiber under high temperature burning. During combustion, the carbonization degree of fiber is high, and it will be extinguished immediately after leaving the flame, and will not ignite in the air. The functional fabric made of seaweed fiber is safer than the traditional clothing fabric made of cotton, linen and chemical fiber in case of fire.

Secondly, there are hydrophilic groups in seaweed fiber macromolecules, which have excellent moisture absorption and moisturizing capacity. And because the seaweed fiber is a wet spinning fiber, there are a lot of micropores in the fiber, which has excellent water absorption and water retention. Its water absorption can reach 20 times of its own weight.

Thirdly, when alginate contacts with tissue exudate, the fiber expands greatly, and a large amount of exudate is kept in the fiber with gel structure. The "gel blocking" property of alginate greatly reduces the dispersion of wound exudates and the impregnation of healthy tissues; The special internal structure of sodium alginate can combine with multivalent metal ions to form a stable complex, which can absorb metal ions greatly and can be used to prepare electromagnetic shielding fabrics. The seaweed fiber belongs to biodegradable fiber, which does not pollute the environment.

The functional fabric of clothing is one of the basic uses of seaweed fiber. In addition, the gel blocking property of seaweed fiber can also be used to make medical dressings such as medical cotton cloth. Alginate fiber has far-infrared function, anti electromagnetic radiation and flame retardant function. It can well shield electromagnetic waves and play a role in radiation protection. Studies have confirmed that seaweed fibers can shield 99.7% of ultraviolet and electromagnetic waves, and can be used to make radiation protective clothing.

Therefore, seaweed fiber functional fabric woven from seaweed fiber is widely used in functional clothing and other special clothing.
