Acetate fiber ntau cov lus qhia
Acetate fiber yog ib hom khoom siv semi-hluavtaws, uas txawv ntawm viscose fiber. Cov kua roj carbon fiber yog cov pob txha caj qaum los ntawm cellulose acetate. Hauv cov kua acetate, feem ntau lossis txhua pawg hydroxyl ntawm lub ntsej muag cellulose yog acetylated. Acetate fiber muaj cov npoo uas yooj yim cylindrical nrog cov kab txaij nyob rau hauv kev coj ua ntu ntev thiab oval duab hauv ntu hla. Vim nws lub siab qis qis thiab kev txiav txim sab, lub acetic ester fiber muaj lub zog tawg tsis zoo, uas phem dua rau hauv lub xeev ntub, tab sis muaj qhov siab elongation thaum tawg, thiab nws cov elastic rov qab yog pom tias muaj zog dua li ntawm viscose fibers. Qhov kev nqus dej noo ntawm acetic ester fiber yog 6% ~ 7% raws li cov txheej txheem, thiab cov cuab yeej o hauv dej yog tsawg. Cov khoom tiav tiav yog yooj yim los ntxuav thiab tsis yog shrinks txawm tias thaum ntxuav nrog dej kub. Acetate fiber muaj cov tshuaj tiv thaiv zoo rau lub hnub ci, thiab ntau dua li nylon, viscose fiber thiab paj rwb fiber. Nws muag thiab deforms thaum rhuab, thiab tom qab ntawd hlawv qeeb, thiab muaj cov khoom sib txuas-txhawb nqa.
