Qhov sib txawv ntawm rayon thiab viscose

Viscose filament hu ua rayon.

Rayon yog cov txiv neej ua fiber ntau tsim los ntawm cellulose (cellulose), thiab cellulose yog cov organic sib xyaw uas suav ua lub hauv paus tseem ceeb ntawm cov nroj tsuag. Vim tias nws yog cellulose fiber, ntau yam khoom zoo ib yam li lwm cov fibers xws li paj rwb thiab flax fibers. Cov fibers yog toothed puag ncig. Viscose cov txiv neej ua cov fiber yog qhov nruab nrab thiab hnyav hom fiber ntau ntawm qhov nruab nrab mus rau lub zog zoo thiab hnav tsis kam, nrog cov khoom siv hydrophilic (cov dej noo rov los ntawm 11%), uas tuaj yeem qhuav qhuav lossis ntxuav hauv kev saib xyuas zoo yam tsis muaj hluav taws xob zoo li qub lossis pilling. Tus nqi tsis kim ib yam nkaus. Qhov kawg ntawm kev siv hluav taws xob yog nyob hauv cov khaub ncaws, kho kom zoo nkauj sab hauv thiab kev lag luam (e.

Viscose staple fiber hu ua paj rwb dag.

Cov paj rwb viscose staple spun los ntawm kev ua tshuaj lom neeg ntawm cov khoom sib txuas polymer ntuj xws li cellulose lossis protein. Nws qhov tshwj xeeb zoo ib yam li paj rwb fiber. Qhov ntev feem ntau yog 35 hli. Lub fineness yog 1.5 ~ 2.2dtex. Nws tuaj yeem siv lub tshuab paj rwb sib tov lossis sib xyaw nrog paj rwb lossis paj rwb hluavtaws fiber ntau (xws li polyester, polyamide, thiab lwm yam). Cov paj rwb luv luv ua los ntawm ntuj cellulose. Feem ntau yog viscose staple fiber. Nws yog qhov tshwj xeeb los ntawm kev ua kom zoo, ua kom siab tshiab thiab nrawm, hnav zoo, tiv taus alkali, thiab nqus dej ze rau paj rwb. Qhov tsis zoo yog tsis muaj kua qaub tsis kam, tsis muaj zog tiv taus thiab qaug zog tiv taus, thiab tsis muaj dej ntub lub zog. Yuav tuaj yeem ua kom zoo dua, lossis tuaj yeem sib xyaw nrog polyester thiab lwm yam tshuaj fiber.

Paj rwb thiab paj rwb dag yog cellulose, thiab cov hmoov txhuv nplej siab sib xws yog qhov sib txawv yog qhov hnyav dua qub. Cov paj rwb dag tau yaj cov cellulose hauv cov kuab tshuaj thiab tshem nws los ntawm cov taub zoo heev los tsim cov filaments, zoo ib yam li kab laug sab. Yog li hlawv yog qhov sib txawv, feem ntau yog siv tes. Cov paj rwb dag yuav tsum du dua.
