Cov ntaub tsis yog woventsis muaj xov warp thiab weft, nws yooj yim txiav thiab xaws, thiab nws yog lub teeb thiab yooj yim teeb tsa.
Qhov zoo ntawm cov ntaub tsis-woven:
1. Lub teeb yuag: polypropylene resin ua cov khoom siv tseem ceeb ntawm cov khoom siv raw, qhov hnyav tshwj xeeb tsuas yog 0.9, tsuas yog peb feem tsib ntawm paj rwb, nrog rau kev ua kom zoo nkauj, zoo nkaus li zoo.
2. Mos: ua los ntawm cov fiber zoo (2-3d) thiab tsim los ntawm lub teeb taw tes kub-yaj nplaum. Cov khoom tiav lawm muaj qhov mos mos thiab xis nyob.
3. Kev rho tawm dej thiab cua permeability: polypropylene seem tsis nqus dej, cov dej ntsiab lus yog xoom, thiab cov khoom tiav lawm muaj dej zoo extraction.
4. Tsis muaj tshuaj lom thiab tsis ua rau khaus: cov khoom no yog tsim los ntawm cov khoom siv raw khoom noj raws li FDA. Nws tsis muaj lwm yam khoom xyaw tshuaj lom neeg.
5. Cov tshuaj tua kab mob thiab tshuaj tua kab mob: polypropylene yog ib hom tshuaj lom neeg tsis muaj zog. Nws tsis noj cov kab thiab tuaj yeem cais cov kab mob thiab kab tsuag hauv cov kua. Cov tshuaj tua kab mob, alkali corrosion thiab cov khoom tiav lawm yuav tsis raug cuam tshuam los ntawm kev yaig.
6. Cov khoom siv tiv thaiv kab mob. Cov khoom siv nrog dej rho tawm, tsis yog pwm, thiab tuaj yeem cais tawm cov kab mob thiab kab hauv cov kua dej, tsis yog pwm thiab npauj npaim.
7. Cov khoom siv lub cev. Los ntawm polypropylene spinning ncaj qha mus rau hauv lub network ntawm kub bonding, cov khoom muaj zog dua li cov khoom luv luv luv yog zoo dua, lub zog tsis muaj kev taw qhia, lub zog zoo sib xws hauv ob qho kev taw qhia.
8. Hais txog kev tiv thaiv ib puag ncig, feem ntau cov ntaub tsis yog woven siv yog polypropylene, thaum polyethylene yog cov khoom siv raw ntawm cov hnab yas. Txawm hais tias ob yam khoom muaj lub npe zoo sib xws, lawv nyob deb ntawm ib leeg hauv cov qauv tshuaj lom neeg. Cov qauv tshuaj lom neeg ntawm polyethylene ruaj khov heev thiab nyuaj rau degrade, yog li nws siv sijhawm 300 xyoo rau cov hnab yas kom decompose. Txawm li cas los xij, cov qauv tshuaj lom neeg ntawm polypropylene tsis muaj zog, thiab cov saw hlau molecular tuaj yeem yooj yim tawg, uas tuaj yeem decompose tau zoo, thiab nkag mus rau lub voj voog ib puag ncig tom ntej hauv daim ntawv tsis muaj tshuaj lom. Lub hnab khw tsis yog woven tuaj yeem decompose tag nrho hauv 90 hnub. Ntxiv mus, cov hnab khw tsis yog woven tuaj yeem siv dua ntau dua 10 zaug, thiab kev ua qias tuaj ib puag ncig tom qab pov tseg tsuas yog 10% ntawm cov hnab yas.
