PET Nonwoven Npuag yog dab tsi?
Polyester (Tsiaj) spunbonded filament nonwoven ntaub yog ib hom non-woven npuag, thiab nws cov khoom siv raw yog 100% polyester chips. Nws yog tsim los ntawm spinning ib tug xov tooj ntawm polyester filaments nruam los ntawm spunbond kub dov. Kuj paub tias tus tsiaj ntawv hu ua non-spunbonded cov ntaub ntawv los yog PES spunbonded nonwoven npuag, tseem hu ua single-component spunbonded nonwoven fabric.
Tus tsiaj tsis muaj zog
Ua ntej, dej repellency. Polyester (PET) spunbonded filament nonwoven npuag yog cov dej-pleev cov tsis-woven npuag, thiab cov dej-cov tshuaj sib hloov ntawm cov ntaub txawv txawv txawv raws li qhov loj me ntawm cov gram. Cov hnyav dua thiab hnyav dua qhov nyhav, qhov dej zoo dua. Yog tias cov dej muaj dej nyob rau ntawm cov pob zeb uas tsis yog, cov dej ntws tuaj yeem ncaj qha tawm ntawm qhov chaw.
Thib ob, kev kub siab ua haujlwm. Txij thaum melting point ntawm polyester yog nyob ib ncig ntawm 260 ° C, qhov ruaj ntseg ntawm cov qhov ntev ntawm cov ntaub npuag nonwoven yuav khaws cia hauv ib qho chaw uas yuav tsum tau ua kom sov kub. Nws tau raug siv los ua thermal hloov luam ntawv, kev sib txuas roj roj pom, thiab qee cov ntaub ntawv sib xyaw uas yuav tsum tau kub kub.
Qhov peb, qhov kev siv yog siab. Polyester (Tsiaj) spunbonded nonwoven npuag yog ib daim ntawv lo ntawm nonwoven npuag thib ob tsuas yog nylon spunbonded nonwoven ntaub. Nws lub zog zoo heev, zoo txog kev ua kom zoo nkauj, tensile rhuav ua hauj thiab kev tiv thaiv kev laus siv los ntawm ntau dua thiab ntau tus neeg nyob hauv ntau cov teb.
Plaub, tiv thaiv gamma rays. Polyester (Tsiaj) spunbond nonwovens kuj muaj cov cuab yeej tshwj xeeb heev: kev tiv thaiv gamma. Uas yog hais tias, yog siv rau ib yam khoom kho mob, nws yuav ncaj qha tau sterilized nrog gamma rays tsis deteriorating lub cev nqaij daim tawv thiab dimensional stability, uas yog lub cuab yeej lub cev uas cov polypropylene (PP) spunbonded nonwoven npuag tsis muaj.
