Natural vs Synthetic Fibers
Fibres yog cov ntaub ntawv zoo li cov xov hauv tsev, lossis ntau dua kom raug, zoo li cov plaub hau uas muaj qhov txuas txuas ntxiv. Cov no tuaj yeem hloov mus rau hauv cov xov muaj zog thiab cov hlua los yog tuaj yeem ua rau lwm cov qauv xws li cov ntawv los yog ntawv los ntawm tangling lawv ua ke siv cov txheej txheem sib txawv. Tsis tas li ntawd, cov xov thiab cov ntawv no tuaj yeem siv rau hauv kev tsim ntau yam ntaub ntawv nyuaj xws li fabrics. Nyob ntawm lub hauv paus chiv keeb, fibers tuaj yeem muab faib ua ob pawg loj; uas yog, ntuj thiab hluavtaws fibers. Ntuj fibers yog muab los ntawm cov nroj tsuag thiab tsiaj txhu, whereas synthetics feem ntau yog tag nrho los yog tsawg kawg yog ib feem neeg tsim.
Ntau ntawm Natural Fibres
Natural fibers yog siv los tsim cov ntaub vim kev nplij siab ntawm cov ntaub ntawv. Qee qhov piv txwv uas paub zoo suav nrog; paj rwb, txhob lo lo ntxhuav thiab ntaub plaub. Tab sis lwm yam ntuj fibers yog siv nyob rau hauv ntau yam industries, los tsim ropes, aerofoils, hnab, txhuam thiab lwm yam txiv maj phaub (coir) fiber, jute, xyoob thiab vine yog ib co piv txwv. Kev siv txhua hom fiber ntau nyob ntawm nws tus kheej cov yam ntxwv xws li lub zog, ua pa thiab lwm yam. Raws li tau hais los saum no, cov fibers ntuj tuaj yeem los ntawm cov tsiaj txhu thiab cov nroj tsuag, qhov chaw cog fibers muaj ntau cellulose xwm thiab tsiaj fibers muaj protein ntau.. Cov nroj tsuag fibers feem ntau yog sau los ntawm ntau qhov chaw ntawm cov nroj tsuag xws li txiv hmab txiv ntoo, nplooj, noob, stalks, straws thiab lwm yam. Fibers los ntawm cov tsiaj feem ntau yog sau los ntawm fiber ntau secreting qog (silk los ntawm silk worm), tsiaj plaub hau (wool los ntawm yaj, cashmere). los ntawm tshis) thiab los ntawm cov noog 'feathers.
Qhov kev tshawb pom ntawm cov hluavtaws fibers txo qhov nrov ntawm ntuj fibers vim lawv cov khoom zoo dua qub thiab ua haujlwm ntev. Txawm li cas los xij, vim qhov nce ntawm cov nqi ntawm cov roj thiab cov khoom siv roj av thiab kuj yog vim muaj kev txhawj xeeb ntawm ib puag ncig, kev xav tau siv cov fibers ntuj tau rov qab los. Lub ntsiab tsis zoo ntawm kev siv cov fiber ntau yog qhov tau txais fiber ntau kim heev. Txawm li cas los xij, qhov yooj yim ntawm kev tuag, kev xav tau siab hauv tib neeg hnav thiab ua ib puag ncig tus phooj ywg tuaj yeem pom tias yog qhov zoo ntawm cov fibers ntuj tshaj cov khoom siv.
Ntau ntawm Synthetic Fibers
Synthetic fibers yog dav siv nyob rau hauv ntau industries, txawm rau tib neeg hnav. Synthetic fibers sai tau txais koob meej vim nws cov khoom tsim nyog tshaj cov fibers ntuj tshwj xeeb tshaj yog thaum nws los txog rau lub zog thiab kav ntev. Lub ntsiab kom zoo dua ntawm kev siv hluavtaws fibers yog tias nws pheej yig heev thaum piv rau ntuj fibers thiab li no txo cov nqi ntau lawm. Cov fibers no feem ntau tiv taus nplaim taws thiab tshuaj lom neeg feem ntau.
Cov tshuaj purity ntawm hluavtaws fibers tuaj yeem paub tseeb zoo tshaj cov fibers zoo li nws tsis muaj plua plav thiab lwm yam khoom tsis zoo xws li cov fibers ntuj. Cov fibers no yuav luag tag nrho cov txiv neej ua los ntawm cov khoom siv petrochemical, thiab raug yuam los ntawm cov khoom siv fiber ntau hu ua spinnerets. Yog li ntawd cov filaments yog tag nrho cov khoom tsim. Yog li, nws muaj peev xwm hloov tau cov qauv tshuaj ntawm cov khoom siv fiber ntau yog tias yuav tsum tau muab nws cov khoom zoo dua qub, uas tsis tuaj yeem ua tau thaum siv cov fibers ntuj. Piv nrog rau ntuj fibers, hluavtaws kuj yog ib qho yooj yim los ntxuav thiab tswj. Txawm li cas los xij, nws tsis yooj yim rau xim hluavtaws fibers nrog dyes vim qhov nqus tsis nrawm thiab yooj yim li nrog cov fibers ntuj. Qee qhov tsis zoo ntawm kev siv hluavtaws fibers yog nws qhov kub thiab txias thiab tsis ua rau ib puag ncig.
Qee cov khoom siv feem ntau suav nrog; Nylon, Polyester, Acrylic, Rayon (cov ntaub lo lo ntxhuav) thiab lwm yam.
Dab tsi yog qhov txawv ntawm Natural Fibers thiab Synthetic Fibers?
• Ntuj fibers yog muab los ntawm cov nroj tsuag thiab tsiaj txhu, whereas hluavtaws fibers yuav luag tag nrho cov txiv neej ua.
• Fabrics ua los ntawm ntuj fibers yog feem ntau xis dua li cov hluavtaws.
• Ntuj fibers kim piv rau hluavtaws fibers.
• Hauv cov fibers hluavtaws, spinnerets yog siv los tsim cov filaments whereas, nyob rau hauv ntuj fibers, nws yog ib txwm ua.
• Ntuj fibers muaj kev siv tsawg thaum piv rau hluavtaws fibers.
• Ntuj fibers yog biodegradable li no ib puag ncig tus phooj ywg, tsis zoo li hluavtaws fibers.
