Polypropylene hnov ​​yog qhov sib dua, hloov tau yooj yim uas yog qhov zoo ntawm kev nqus cov kua. Tsis tsuas yog nws muaj peev xwm tiv taus siab dua cov khoom thauj khoom dua li lwm cov khoom siv, tab sis nws kuj kub tiv taus thiab tiv taus tshuaj thiab feem ntau cov kev daws teeb meem.Txhua tag nrho nws cov txiaj ntsig, nonwoven polypropylene kuj yog cov khoom siv qis.Polypropylene rab koob punched muaj PP tsis yog woven interlining npuag yob muaj cov yoog yooj, eco-freindly, permeability, waterproof, anti-rub, tsim kua muag-tiv thaiv thiab hmoov av.

Polypropylene rab koob punched lim tau ua los ntawm polypropylene fiber thiab muaj qhov kub qis tshaj kev ua haujlwm. Vim tias polypropylene fiber muaj zoo tshaj acid tiv thaiv, alkalinity thiab qis muag taw tes tshaj polyester fiber, thiab hydrolysis ruaj ntseg ntawm polypropylene fiber yog qhov zoo, polypropylene koob punching Felt feem ntau yog siv nyob rau hauv cov roj flue kub hauv qab 100 ℃ thiab siab acid thiab alkalinity los yog hauv thaj chaw muaj kua thiab sib cais sib xyaw nrog cov acidity loj thiab alkalinity thiab cov ntsiab lus noo loj. Cov polypropylene xav siv rau cov kua-sib cais sib cais siv cov sib txawv ntawm cov polypropylene fiber, thiab siv cov ntaub qhwv zoo tib yam los yog lub zog siab los ua cov khoom tiv thaiv hauv paus ntaub, uas tuaj yeem ua tiav los ntawm kub dov thiab hu nkauj. Nws yog siv ua ke nrog kua lim lim cov khoom sib cais xws li phaj thiab thav duab lim xovxwm, lub tshuab nqus ntim tawm, lim hnab thiab lub tshuab lim centrifugal.
