Cov Yam Ntxim Saib Xyuas Thiab Kev Zoo Los Ntawm Rayon Npuag

Cov yam ntxwv thiab qhov zoo ntawm cov ntaub rayon

Cov yam ntxwv ntawm rayon npuag ：

Cov pib muaj pes tsawg leeg ntawm viscose fiber yog cellulose (C6H10O5) tsis muaj cov viscose fiber ntau muaj cov zigzag-puab tus qauv ntu hauv ntu hla, thiab cov lus qhia ntev yog ncaj thiab grooved. Lub fiber-nplua nuj core-free qauv muaj ib ncig kab sib tshooj. Viscose fiber muaj zoo hygroscopicity, thiab nyob rau hauv ib txwm muaj huab cua puag ncig, noo noo rov qab tus nqi yog li 13%. Qhov teeb meem tawg tom qab nqus dej noo, lub taub tau nce txog li 50%, yog li cov ntaub tawv tawv tom qab tso dej tawm, thiab qhov ntsws qhov loj dua. Lub zog tawg ntawm cov viscose fiber zoo tib yam yog me dua cov paj rwb, uas yog kwv yees li 1.6 ~ 2.7cN / dtex; qhov elongation thaum tawg yog loj dua li ntawm paj rwb, uas yog 16% ~ 22%; lub zog ntub dej ntog ntau dua, txog 50% ntawm lub zog qhuav, ntub dej ncab Qhov nce ntxiv yog li 50%. Cov qauv hloov qis dua li ntawm cov paj rwb, thiab nws yooj yim deformed hauv qab me me, thiab cov cuab yeej elastic rov qab los tsis zoo, yog li cov ntaub yooj yim elongated thiab qhov ntev seem tsis zoo. Lub zog ntawm cov nplua nuj fiber ntau, tshwj xeeb tshaj yog lub zog ntub dej, yog siab dua qhov ntawm cov nplaum tshwj xeeb, elongation thaum tawg yog me me, thiab qhov ntev seem yog qhov zoo. Cov viscose zoo tib yam muaj hnav tsis zoo, thaum muaj cov nplua nuj fiber ntau tau zoo tuaj. Cov tshuaj lom neeg muaj pes tsawg hauv viscose fiber zoo ib yam li cov paj rwb, yog li nws tiv taus alkali dua li cov kua qaub, tab sis alkali thiab acid tsis zoo dua li paj rwb. Cov nplua nuj fiber ntau muaj alkali thiab acid tsis kam. Ib yam li ntawd, cov viscose fiber muaj cov khoom zoo sib xws rau cov paj rwb, thiab cov dyeing chromatogram tiav thiab cov xim ua tau zoo. Tsis tas li ntawd, cov thermal thaj chaw ntawm viscose fiber yog zoo ib yam li cov paj rwb, thiab qhov ntom tau ze rau paj rwb ntawm 1.50 ~ 1.52g / cm3. Lub hydroxyl pawg ntawm macromolecule ntawm cellulose yog lub luag haujlwm raug rau ntau yam kev siv tshuaj lom neeg. Yog li no, viscose fiber tuaj yeem hloov kho los ntawm kev sib tsoo los yog cov zoo li los txhim kho cov khoom ntawm cov viscose fiber thiab ua ntau yam tshwj xeeb-ua cov fibers.

Zoo ntawm rayon npuag:

Zoo hygroscopicity, xis hnav, zoo heev spinnability, feem ntau xyaw nrog paj rwb, ntaub plaub lossis ntau cov hluavtaws ua ke, kev sib tshuam, siv rau txhua hom khaub ncaws thiab zoo nkauj ntawm cov ntaub. High-lub zog viscose fiber kuj tseem siv tau hauv cov khoom lag luam xws li cov hlua log thiab cov siv tawv conveyor. Viscose fiber yog siv cov tshuaj fiber ntau.
