1. kev txheeb xyuas cov ntaub ntawv
PP non-woven npuag: Cov fiber ntau siv rau cov ntaub tsis-woven yog polypropylene, uas yog cov khoom siv hluavtaws tau los ntawm polymerization ntawm propylene.
Polyester non-woven npuag: cov fiber ntau siv rau cov ntaub ntawv tsis-woven yog polyester fiber, uas yog cov hluavtaws fiber ntau tau los ntawm spinning polyester condensed los ntawm organic dibasic acid thiab diol.
2. Qhov sib txawv
PP non-woven npuag: Nws qhov ceev tsuas yog 0.91g / cm3, uas yog qhov sib txawv ntawm cov tshuaj fiber ntau.
Polyester nonwoven npuag: Thaum polyester yog amorphous kiag li, nws qhov ceev yog 1.333g / cm3.
3. Lub teeb sib txawv
PP non-woven npuag: tsis zoo lub teeb tsis kam, insolation kuj, yooj yim aging thiab nkig poob.
Polyester non-woven npuag: zoo lub teeb tsis kam, tsuas yog 60% lub zog poob tom qab 600h hnub ci irradiation.
4. Cov khoom siv thermal sib txawv
PP non-woven npuag: tsis zoo thermal stability, tsis tiv taus ironing.
Polyester non-woven npuag: zoo kub tsis kam, melting point ntawm txog 255 ℃, thiab ruaj khov zoo nyob rau hauv ib tug ntau yam ntawm kawg-siv tej yam kev mob.
5, sib txawv alkali tsis kam
Polypropylene non-woven npuag: Polypropylene muaj cov tshuaj tiv thaiv zoo, thiab dhau li ntawm cov dej qab zib muaj zog, polypropylene muaj alkali tsis kam.
Polyester non-woven npuag: Polyester muaj cov alkali tsis zoo, uas tuaj yeem ua rau cov fiber ntau puas thaum nws hnov mob nrog alkali nyob rau hauv chav tsev kub thiab dilute alkali ntawm qhov kub thiab txias.Nws tsuas yog ruaj khov rau dilute alkali lossis qaug zog alkali ntawm qhov kub thiab txias.
