Qhov sib txawv tseem ceeb ntawm cellulosic thiab hluavtaws fibers yog tias cellulosic fibers yog ib txwm tshwm sim los yog tib neeg tsim fibers siv tej yam ntuj tso xws li cog qhov chaw, whereas hluavtaws fibers yog tseem ceeb tib neeg tsim fibers ua nrog roj av roj.
Cellulosic thiab hluavtaws fibers yog ob hom loj ntawm fibers uas muaj xws li ntuj lossis khoom siv ntawm fiber.
Cellulosic Fiber yog dab tsi?
Cellulosic fiber yog ib hom fiber ntau ua los ntawm ethers lossis esters ntawm cellulose. Cov cellulose pub no tuaj yeem tau los ntawm cov tawv ntoo, ntoo, lossis nplooj ntawm cov nroj tsuag. Peb kuj tuaj yeem siv lwm cov khoom siv cog ntoo. Tsis tas li ntawd, cellulosic fibers kuj muaj hemicellulose thiab lignin, muaj ntau feem pua ntawm txhua yam, uas hloov cov khoom siv ntawm cov fiber ntau.
Thaum xav txog cov qauv tshuaj ntawm cov cellulosic fibers, cellulose muaj cov qauv polymer uas muaj ntau cov qabzib rov ua dua tshiab uas txuas nrog rau qhov kawg-rau-kawg qauv. Nws yog cov khoom siv polymer ncaj nraim uas muaj qhov ntev, zoo li tus pas nrig. Cellulosic fibers muaj microfibrils ntawm cellulose nyob rau hauv ib tug matrix qauv uas muaj hemicellulose thiab lignin. Muaj hydrogen bonds nruab nrab ntawm cov saw ntev ntawm cellulose nyob rau hauv natural cellulosic fibers, uas ua rau nws nruj thiab muaj zog.
Muaj ntau hom cellulosic fibers, xws li ntuj cellulosic fibers thiab hluavtaws cellulosic fibers. Ntuj cellulosic fibers yog qhov chaw ntawm cov nroj tsuag, e.g. paj rwb fibers, linen fibers, thiab lwm yam. Synthetic los yog manufactured cellulosic fibers yog tsim los ntawm cov nroj tsuag thiab yog ua tiav rau hauv ib tug sis plawv hniav, uas yog ces extruded tib yam li polyester los yog nylon ntau lawm. Feem ntau cov hluavtaws cellulosic fibers muaj xws li rayon thiab viscose.
Daim duab 01: Cov qauv ntawm Cellulosic Fibers
Muaj ntau daim ntawv thov ntawm cellulosic fibers, suav nrog kev lag luam textile, ua cov ntaub ntawv sib xyaw uas peb tuaj yeem muab cov cellulosic fiber ntau nrog lwm cov khoom los ua cov khoom tawv tawv dua. Cov khoom no yog ib qho tseem ceeb hauv cov txheej txheem lim kom lim cov khoom xws li hmoov cellulose, thiab lwm yam.
YDab tsi yog Synthetic Fiber?
Synthetic fiber yog ib hom txiv neej ua fibers, ua los ntawm roj av. Feem ntau, hom fiber ntau no yog tsim los ntawm cov polymers uas peb tuaj yeem pom hauv cov pa roj carbon monoxide thiab lwm yam khoom siv roj av. Qhov tseem ceeb tshaj, tag nrho cov ntaub yog feem ntau yog tsim los ntawm cov khoom tsim los yog cov khoom siv fiber ntau. Cov hluavtaws fibers no muaj ib chav tsev me me lossis ib lub polymer uas yog tsim los ntawm cov monomers (rov ua dua units ntawm polymer). Cov khoom siv hluavtaws loj muaj xws li nylon, acrylic, polyurethane, thiab polypropylene. Daim ntawv no ntawm hluavtaws fiber ntau yog tsim nyob rau hauv lab tons thoob plaws ntiaj teb txhua xyoo.
Daim duab 02: Synthetic Fibers
Peb tuaj yeem faib cov hluavtaws fibers rau hauv peb pawg xws li rayon, nylon, thiab polyester. Rayon yog tsim los ntawm cov ntoo pulp, thiab nylon yog tsim los ntawm cov thee, dej thiab cua, whereas polyester yog tsim los ntawm cov thee dej, cua thiab roj av.
Muaj ntau qhov zoo ntawm cov khoom siv hluavtaws, uas suav nrog kev ua haujlwm siab, nyuaj rau wrinkling, elastic xwm, muaj zog muaj peev xwm txhawb nqa lub nra hnyav, thiab tus nqi qis. Txawm li cas los xij, tuaj yeem muaj qee qhov tsis zoo, uas suav nrog kev nyuaj ntawm kev nqus dej noo, cuam tshuam hauv kev ntxuav nrog dej kub, thiab nyiam kom tua hluav taws yooj yim.
Qhov txawv ntawm Cellulosic thiab Synthetic Fiber yog dab tsi?
Cellulosic thiab hluavtaws fibers yog ob hom loj ntawm fibers uas muaj xws li ntuj los yog khoom siv ntawm fiber. Qhov sib txawv tseem ceeb ntawm cellulosic thiab hluavtaws fibers yog tias cellulosic fibers yog ib txwm tshwm sim los yog tib neeg tsim fibers siv tej qhov chaw xws li cov nroj tsuag qhov chaw whereas hluavtaws fibers yog tseem ceeb tib neeg tsim fibers ua nrog roj av roj.
Cov infographic hauv qab no teev qhov sib txawv ntawm cellulosic thiab hluavtaws fiber ntau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Cellulosic vs Synthetic Fiber
Cellulosic thiab hluavtaws fibers yog ob hom loj ntawm fibers uas muaj xws li ntuj los yog khoom siv ntawm fiber. Qhov sib txawv tseem ceeb ntawm cellulosic thiab hluavtaws fibers yog tias cellulosic fibers yog ib txwm tshwm sim los yog tib neeg tsim fibers siv tej qhov chaw xws li cov nroj tsuag qhov chaw whereas hluavtaws fibers yog tseem ceeb tib neeg tsim fibers ua nrog roj av roj.
