New chemical fiber fabric chitin fiber fabric

Chitin fibers and chitosan fibers are produced using chitin or chitosan solution, which is a kind of natural polymer fiber after cellulose fiber. Chitin is a natural biopolymer extracted from the algae's cell wall by the shells and fungi of shrimps, crabs, and insects. When chitosan is treated with concentrated alkali, chitin is deacetylated.

Chitin fiber mixed with viscose fiber is the most common chitin fiber in the market. Pure chitin fibers are mostly used as medical textiles. Most of the chitin fiber used is blended fibers. Currently, there are chitin fibers/cotton blends, chitin fibers/losing wheels/viscose fiber blends, and chitin fibers/cotton/hair blends. Fabric.

A chitin fiber knitted fabric

Using chitin fiber (182dtex, 145dtex)/far-infrared fiber/cotton blended yarn, ribs, double ribs, and changing structures on the large circular machine can produce fabrics with both antibacterial and far infrared capabilities. Fabric feels soft, bright after dyeing, suitable for men and women underwear, pajamas, casual clothes, children's clothing, socks, gloves and so on.

Double-shell woven fabric

The use of 40% tops 125dtex, 20% soy protein fiber, 40% chitin fiber blends, the use of changes in tissue or twill tissue chitin developed antibacterial comfort is a high-end use of woven fabrics. The fabric has a fine surface, comfortable feel, natural luster, antibacterial, antibacterial and health functions, suitable for making high-end shirts and women's clothing.

Three medical textiles

Surgical suture

The purified chitin powder is dissolved in a suitable solvent (such as an amide solvent), and the Sis is obtained by wet spinning, and then spun into different types of sutures. This type of surgical suture made from high quality chitin can accelerate wound healing, can be degraded and absorbed by the tissue, and can replace the surgical line of the casing, and the performance is superior to the casing line in many aspects. The mechanical properties of chitin suture are good and can meet the clinical requirements well.

2. Medical dressing

The opened chitin or chitosan short fibers are carded into a net, and then laminated, sized, dried or needled into a medical nonwoven fabric. This gauze or non-woven fabric is porous, has good air permeability and water absorption, air permeability is 1500L/m2·s, water absorption is 15%, it is cut into various specifications, and it becomes ideal medical dressing after being disinfected by packaging. .
