Lub zog muaj zog PP filament spunbond koob punched nonwoven geotextile

(1) Cov polypropylene muaj qhov ntom ntom ntom tsuas yog 0.91 g / m3 (polyester yog 1,38 g / m3), yog li cov polypropylene geotextile muaj thaj chaw loj dua nyob hauv tib lub zog ntawm cov ntaub polyester.

(2) Tus qauv tshwj xeeb ntawm polypropylene ua rau nws muaj cov kua qaub zoo thiab alkali tsis kam, tshwj xeeb tshaj yog alkali tsis kam zoo dua li polyester. Nws ua tau zoo thaum siv hauv kev tiv thaiv, ntxiv dag zog, tiv thaiv dej tsis ua haujlwm thiab tiv thaiv xeb ntawm cov av hauv av nrog cov acidity muaj zog thiab alkalinity dua li polyester.

(3) Qhov txhuam kev sib txhuam coefficient ntawm polypropylene fiber yog qhov me me, kev sib txhuam ntawm cov fibers yog me me, thiab kev hnav tsis kam yog qhov zoo, thiab qhov kev sib txhuam los tiv thaiv kev co ua tau zoo dua li polyester.

(4) Polypropylene tau zoo hydrophobicity, tsis muaj dej nqus, thiab yog zoo dua rau polyester hauv kev tso dej thiab kua txua engineering.

(5) Acrylic fiber koob koob ntaus ntaub yog qhov muaj zog tshaj qhov qub ntawm polyester koob-punched geotextile, thiab lub zog ntsug thiab kab rov tav yog sib npaug.
