Cov xov tsis yog ntaub tshiab yog ib tiam tshiab ntawm kev tiv thaiv ib puag ncig cov ntaub ntawv, uas muaj cov khoom hauv kev qhia ua ke lossis cov fibers. Nws yog cov dej noo-pov thawj, ua tsis taus pa, hloov pauv, lub teeb yuag, tsis muaj kev sib txuas nrog txhawb, yooj yim rau ploj, tsis muaj tshuaj lom thiab tsis mob, nplua nuj xim, tsis tshua muaj nqi thiab rov ua dua tshiab. Piv txwv li, polypropylene (PP) granules feem ntau yog siv los ua cov khoom siv raw, uas yog tsim los ntawm kev txuas ntxiv ib kauj ruam ntawm kev kub siab yaj, hlau txau, xov txheej thiab kub nias txheej. Nws hu ua daim ntaub vim nws qhov tsos thiab qee yam ntxwv.
Cov xov tsis-xaws yog ib yam tshiab ntawm cov khoom siv fiber ntau nrog cov mos, ua pa thiab dav hlau qauv. Nws muaj qhov zoo ntawm tsis muaj fiber ntau daim tawv, muaj zog, ruaj thiab silky mos. Nws kuj yog ib hom khoom siv txhawb zog, thiab muaj lub siab ntawm paj rwb. Piv nrog paj rwb ntaub, lub hnab ntawm tsis-cov ntaub yog yooj yim rau kev tsim thiab pheej yig ua. Qhov tsis zoo ntawm cov ntaub tsis-nws yog nws lub zog tsis zoo thiab kav ntev, thiab nws tsis tuaj yeem ntxuav zoo li lwm cov ntaub. Vim tias cov fibers tau teem rau hauv ib qho kev taw qhia, nws yooj yim cais tawm ntawm txoj cai kaum sab xis.
Nws yog lub cim tshiab ntawm cov khoom siv kev tiv thaiv ib puag ncig, nrog dej pleev cov tshuaj, ua pa, hloov pauv, tsis txhuam, tsis mob, tsis mob, tsis mob, xim thiab lwm yam. Thaum hlawv, nws yog non-toxic, mov thiab tsis muaj cov khoom seem, yog li nws tsis ua paug rau ib puag ncig, yog li kev tiv thaiv ib puag ncig los ntawm nws. Cov qauv ua tshuaj ntawm polypropylene tsis ruaj, lub molecular saw tuaj yeem tawg tau yooj yim, yog li nws tuaj yeem ua kom zoo, thiab nkag mus rau ib puag ncig puag ncig tom ntej hauv daim ntawv tsis muaj tshuaj lom.
