100g-600g breathable permeable polypropylene luv fiber koob punched tsis woven geotextile

Hauv kev tsim cov ntaub tsis-woven, polyester (PET) thiab polypropylene (PP) tseem yog cov ntaub ntawv tseem ceeb, suav txog ntau dua 95% ntawm tag nrho cov ntaub ntawv fiber ntau siv hauv cov ntaub tsis-woven. Cov geotextile ua los ntawm polypropylene fibers los ntawm koob punching yog polypropylene geotextile, tseem hu ua polypropylene geotextile lossis polypropylene ntaub. Polypropylene luv fiber koob punched nonwoven geotextiles muab faib ua ob hom: polypropylene luv fiber geotextiles thiab polypropylene ntev fiber ntau geotextiles.

Cov yam ntxwv ntawm polypropylene luv fiber koob punched nonwoven geotextile suav nrog:

(1) Lub zog zoo. Lub zog yog me ntsis qis dua rau PET, tab sis muaj zog dua li cov fibers zoo tib yam, nrog cov pob txha elongation ntawm 35% mus rau 60%; Yuav tsum muaj lub zog muaj zog, nrog lub pob txha elongation ntawm 35% mus rau 60%;

(2) Zoo elasticity. Nws txoj kev rov qab sai sai yog qhov zoo dua li PET fiber ntau, tab sis nws yog qhov phem dua li PET fiber ntau nyob rau hauv lub xeev kev ntxhov siab ntev; Tab sis nyob rau hauv lub sij hawm ntev kev ntxhov siab, nws yog phem tshaj PET fibers;

(3) Tsis zoo cua sov. Nws qhov softening point yog nyob nruab nrab ntawm 130 ℃ thiab 160 ℃, thiab nws melting point ntawm 165 ℃ thiab 173 ℃. Nws thermal shrinkage tus nqi yog li ntawm 165 ℃ mus rau 173 ℃ ntawm qhov kub thiab txias ntawm 130 ℃ hauv qhov chaw. Nws cov thermal shrinkage tus nqi yog qhov zoo ib yam li PET tom qab 30 feeb ntawm qhov kub ntawm 130 ℃ hauv qhov chaw, thiab tus nqi shrinkage yog qhov pib zoo ib yam li PET tom qab 30 feeb ntawm qhov kub ntawm ib ncig ntawm 215%;

(4) Zoo hnav tsis kam. Vim nws cov elasticity zoo thiab tawg ua haujlwm tshwj xeeb, nws muaj kev hnav zoo heev;

(5) Lub teeb hnyav. Qhov tshwj xeeb lub ntiajteb txawj nqus ntawm polypropylene luv fiber koob punched nonwoven geotextile tsuas yog 0191g / cm3, uas yog tsawg dua 66% ntawm PET;

(6) Zoo hydrophobicity. Polypropylene luv fiber koob punched nonwoven geotextile muaj cov dej noo nyob ze rau xoom, yuav luag tsis muaj dej nqus, thiab noo noo rov qab ntawm 0105%, uas yog li 8 npaug qis dua PET;

(7) Zoo core suction kev ua tau zoo. Polypropylene luv fiber koob punched nonwoven geotextile nws tus kheej muaj qhov nqus dej tsawg heev (yuav luag xoom), thiab muaj cov tub ntxhais nqus dej zoo, uas tuaj yeem hloov dej raws cov fiber ntau rau sab nrauv;
(8) Lub teeb tsis zoo. Polypropylene luv fiber koob punched nonwoven geotextiles muaj tsis zoo UV tsis kam thiab muaj kev laus thiab decomposition nyob rau hauv tshav ntuj;
(9) Tshuaj tiv thaiv. Nws muaj kev tiv thaiv zoo rau acidity thiab alkalinity, thiab nws cov kev ua tau zoo tshaj ntawm PET fibers.
