Guangdong Institute of Textile Technolegy Structures of wool fibers Submicrostructure Cotex core of the wool fiber: 90% of the fiber volume, consists of countless long, spindle-shaped- cells held together by intercellular cement
Guangdong Instltute of Textile Technolegy Introduction Fibers in which forming substance is cellulose acetate where not less than 92% of hydroxyl groups are acetylated: replacing -OH groups with -COCH3. Acetate: 2 of 3 -0H groups in each 6- member ring are acetylated; ~2.5 Triacetate: Nearly all -OH groups are replaced 2.91~2.96
Guangdong Instltute of Textile Technolegy Island in sea Manufacturing process Suspension of droplets of one component in matrix of the other Two components should have similar melting temperatures Can make composite fiber
