Khoom cua hluavtaws yog cov uas yog neeg tsim thiab tau txais los ntawm kev sib xyaw ntawm ntau hom tshuaj lom neeg thiab cov khoom siv raw xws li petrochemicals. Lawv suav nrog nylon, acrylic, polyester thiab lwm yam. Cov no fibers kuj hu ua dag los yog neeg ua fibers.

Kuj paub, dab tsi yog hu ua hluavtaws Fiber?

Txhais ntawm hluavtaws fiber ntau .: ib qho ntawm ntau yam txiv neej ua textile fibers suav nrog feem ntau yog cov khoom tsim los ntawm cov khoom siv ntuj tsim (xws li rayon thiab acetate los ntawm cellulose los yog cov protein tsim dua tshiab fibers los ntawm zein lossis casein) nrog rau tag nrho hluavtaws fibers (xws li nylon lossis acrylic fibers ) - piv polymer.

Qhov thib ob, kev siv cov hluavtaws fibers yog dab tsi? Nws yog siv nyob rau hauv kev tsim cov hlua, nets rau nuv ntses thiab lub rooj zaum siv. Polyester - Cov ntaub no yog tsim los ntawm cov thee thiab roj thiab tsis muaj wrinkle thiab yooj yim los ntxuav. Nws yog siv rau kev tsim cov kaus mom, raincoats, thiab ropes.
