Ua ntej, polyester (PET) spunbonded filament non-woven npuag yog ib hom dej pleev cov cov xim tsis-ntaub qhwv ntaub. Cov dej pleev cov ntaub ntawm cov ntaub qhwv tsis-sib txawv yog txawv raws qhov hnyav. Qhov loj dua thiab hnyav dua lub gram hnyav yog, qhov zoo dua qhov dej hloov pauv yog qhov. Yog hais tias muaj dej txauv rau ntawm cov npoo uas tsis yog ntaub npuag, cov dej poob yuav poob ncaj qha rau saum npoo av.
Thib ob, siab kub ua hauj. Vim tias qhov chaw yaj ntawm polyester yog 260 ° C, nyob rau qhov xav tau ntawm qhov kub thiab txias ib puag ncig, tuaj yeem ua kom muaj qhov ruaj khov ntawm cov ntaub qhwv tsis-ntaub qhov ntev. Nws tau siv dav hauv tshav kub hloov luam ntawv, xa cov roj pom, thiab qee cov khoom siv sib xyaw uas xav tau siab kub.
Thirdly, PET spunbonded nonwovens yog ib hom ntawm cov filament nonwovens thib ob tsuas yog nylon spunbonded nonwovens. Nws lub zog zoo, huab cua zoo permeability, tensile, tsim kua muag tsis kam thiab tiv thaiv kev laus cov khoom tau siv rau ntau thiab ntau tus neeg hauv ntau daim teb.
Plaub, PET spunbonded nonwovens tseem muaj lub zog tshwj xeeb lub cev: gamma ray tsis kam. Hauv lwm lo lus, yog tias nws tau thov rau cov khoom lag luam kho mob, nws tuaj yeem muab tshuaj tua kab mob ncaj qha tsis muaj kev puas tsuaj rau cov khoom siv lub cev thiab lub cev qhov chaw ruaj khov, uas yog cov khoom lub cev uas polypropylene (PP) spunbonded tsis-ntaub npuag tsis muaj.
