The progress of technology is not only Increased yarn strength

Naia™ cellulose Draw textured yarn manufacturers fiber is essentially diacetate fiber, English name Cellulose Di-acetate, abbreviated as CDA. In addition, there are triacetate fiber, the English name is Cellulose Tri-acetate, abbreviated as CTA.

The initial raw material is pulp processed by FS; and PEFCTM certified wood. After acetylation, 74% to 92% of the hydroxyl groups in cellulose react with acetic anhydride to form cellulose acetate, which is then dry-spun. . The fiber classification is the same as that of Modal and Lyocell, and belongs to the category of regenerated cellulose fiber.

The characteristics of the linear density material determine that the strength of the acetate cellulose fiber is relatively low. The initial linear density of the monofilament is about 4.0 D. With the continuous innovation of production technology, the minimum linear density of the monofilament can reach 0.75 D.

The progress of technology is not only Increased yarn strength, improved processing performance, and optimized product style and feel. Moisture absorption and electrical conductivity Naia™ acetate cellulose fiber contains a certain number of hydrophilic hydroxyl groups, its nominal moisture regain is 6.5%, lower than other regenerated cellulose fibers, but much higher than other synthetic fibers such as polyester.

The esterification of most hydroxyl groups makes NaiaTM acetate cellulose fiber not swell vigorously due to large amount of water absorption, reflecting perfect dimensional stability, quick-drying performance and printing and dyeing processing advantages. Proper hygroscopicity, so that it will not generate static electricity. The specific resistance of the material is about 1.9×107Ω·cm, so the short fiber also shows good spinnability. Physical properties such as strength and stretching The dry strength of acetate cellulose fiber is about 1.2 ~ 1.4 cN/dtex,
