Acetate Fiber Bundle Ua li cas

Kev npaj cov khoom siv raw: Cov ntaub ntawv tseem ceeb muaj xws li ntoo pulp, acetic acid, acetic anhydride, sulfuric acid, acetone, thiab lwm yam.
Kev kho acetylation: Ntoo pulp yog acetylated los tsim cellulose acetate flakes.
Dissolution thiab spinning: Dissolve cellulose acetate flakes nyob rau hauv acetone thiab spin lawv mus rau hauv fiber strands siv lub tshuab spinning.
Bundle thiab Curl: Cov hlua fiber ntau yog ncab los ntawm cov hlua khi thiab tom qab ntawd curled thiab deformed los ntawm lub tshuab curling.
Kev ziab thiab rov ua dua: Cov pob fiber ntau curled tau qhuav hauv lub tshuab ziab khaub ncaws thaum rov qab acetone.
Ntim: Thaum kawg, ntim cov fiber ntau qhuav rau hauv cov khoom tiav.
