Teb: Qee cov fibers hu ua hluavtaws vim lawv yog tsim los ntawm tib neeg. Kos lo lus teb raug. Nws muaj a txhob lo lo ntxhuav zoo li.

Raws li, vim li cas qee cov fibers hu ua hluavtaws?

Teb: Qee cov fibers uas tsis yog ntuj tsim (neeg tsim fibers ) hu ua hluavtaws vim tias lawv tau tsim los ntawm kev ua tshuaj lom neeg ntawm petrochemicals. Cov hluavtaws fibers yog ua los ntawm cov loj heev units hu ua polymers. Ib txhia ntawm hluavtaws fibers yog rayon, nylon thiab acryl rau.

Qhov thib ob, qhov sib txawv ntawm cov hluavtaws hluavtaws yog dab tsi? Muaj ob hom ntawm fibers - Ib qho yog ntuj tsim fibers uas tau los ntawm tej yam ntuj tso e.g. Paj rwb, txhob lo lo ntxhuav, ntaub plaub thiab lwm yam yog hluavtaws fibers uas yog man-made piv txwv li – rayon, nylon, acrylic thiab lwm yam II. A Khoom cua Fiber yog cov saw hlau me me ntawm cov tshuaj lom neeg sib koom ua ke.

Tom qab ntawd, ib tus tseem yuav nug tau tias, cov khoom siv hluavtaws Fibers yog dab tsi Vim li cas lawv thiaj hu ua polymers piav qhia los ntawm kev ua piv txwv?

Khoom cua hluavtaws : Cov no yog neeg tsim yog hu ua man-made los yog hluavtaws fibers . Piv txwv : rayon, nylon, acrylic, thiab lwm yam (i) Khoom cua hluavtaws yog ua los ntawm cov khoom me me ntawm cov tshuaj sib xyaw ua ke nyob rau hauv daim ntawv ntawm cov saw loj. Cov saw tsim yog hu ua polymer . Yog li, a polymer yog ua los ntawm ntau chav nyob rov ua dua.

Vim li cas Rayon txawv ntawm cov hluavtaws hluavtaws?

Rayon txawv ntawm cov khoom siv hluavtaws vim: Nws muaj ib tug txhob lo lo ntxhuav zoo li. Nws yog tau los ntawm ntoo pulp. Nws fibers kuj tuaj yeem ua tau zoo li cov khoom ntuj fibers.
