Tus txiv neej ua fiber ntau, fiber ntau uas nws cov tshuaj muaj pes tsawg leeg, qauv, thiab cov khoom raug hloov pauv thaum lub sijhawm tsim khoom. … Raws li cov fibers, cov ntaub ntawv no tau txais txiaj ntsig rau lawv lub zog, tawv, tsis kam rau tshav kub thiab pwm, thiab muaj peev xwm tuav daim ntawv nias.
Dab tsi yog txiv neej ua fibers?
Manmade fibers yog tsim los ntawm ntau yam tshuaj, los yog regenerated los ntawm cov nroj tsuag fibers. Piv txwv ntawm manmade fibers yog: polyester; polyamide (nylon); acrylics; viscose, ua los ntawm cov tawv ntoo; Kevlar, fiber ntau ua haujlwm; thiab Nomex, ib qho kev ua tau zoo fiber ntau.
Qhov txiaj ntsig ntawm kev siv txiv neej ua ntaub yog dab tsi?
Synthetic fibers muaj qhov zoo hauv qab no. Feem ntau cov hluavtaws fibers muaj elasticity zooFeem ntau cov ntaub uas ua los ntawm hluavtaws fibers tsis wrinkle yooj yim. Cov ntaub uas ua los ntawm cov hluavtaws fibers feem ntau yog siv tau ntau dua, tsis tshua muaj nqi, thiab yooj yim dua li cov uas ua los ntawm ntuj fibers.
Vim li cas tib neeg tsim fibers siv ntau dua li ntuj fibers?
Feem ntau, cov fibers ntuj muaj zog tsawg thiab ua haujlwm ntev, qhov manmade fibers muab lub zog ntau dua thiab ruaj khovQhov no yog vim li cas cov khaub ncaws ua rau kev tawm dag zog yog tsim los ntawm manmade fibers. Spandex thiab rayon feem ntau yog siv rau cov khoom, uas yuav tsum tau ua kom ntev.
Tus yam ntxwv ntawm tus txiv neej ua fibers yog dab tsi?
