Tsis-woven polypropylene vs polyester

Nonwoven fabrics tsis yog woven fabrics, tab sis yog tsim los ntawm oriented los yog random fiber ntau, yog li lawv kuj hu ua non woven fabrics. Vim muaj cov khoom sib txawv thiab cov txheej txheem ntau lawm, cov ntaub tsis-woven tuaj yeem muab faib ua ntau hom, xws lipolyester non-woven fabrics, polypropylene non-woven fabrics, thiab lwm yam.

Cov neeg siv khoom feem ntau nug txog qhov sib txawv ntawm polyester non-woven npuag, polypropylene non-woven npuag, polypropylene fiber, thiab polyester thaum sab laj cov khoom tsis-woven npuag. Hauv qab no yog cov npe ntawm lawv qhov sib txawv.

PET non-woven npuag

PET spunbond filament non-woven npuag yog ib hom dej tiv thaiv tsis-woven npuag, thiab nws cov dej tiv thaiv kev ua haujlwm txawv nyob ntawm qhov hnyav ntawm cov ntaub. Qhov loj thiab tuab qhov hnyav, qhov zoo dua cov dej tiv thaiv kev ua haujlwm. Yog hais tias muaj cov tee dej ntawm cov ntaub ntawv uas tsis yog-woven, cov tee dej yuav ncaj qha tawm ntawm qhov chaw.

Polyester non-woven npuag yog resistant rau kub kub. Vim lub melting point ntawm polyester nyob ib ncig ntawm 260 ° C, nws muaj peev xwm tuav lub stability ntawm sab nraud qhov ntev ntawm non-woven fabrics nyob rau hauv ib puag ncig uas yuav tsum tau kub kuj. Nws tau dav siv nyob rau hauv tshav kub hloov luam ntawv, pom cov roj kis tau tus mob, thiab qee cov ntaub ntawv sib xyaw uas yuav tsum tau muaj qhov kub thiab txias.

PET spunbond non-woven npuagyog ib hom filament non-woven npuag thib ob nkaus xwb rau nylon spunbond non-woven npuag. Nws zoo heev lub zog, zoo huab cua permeability, tensile kuj, tsim kua muag kuj thiab anti-aging zog tau siv nyob rau hauv ntau yam teb los ntawm ntau thiab ntau tus neeg.

PET spunbond non-woven npuag kuj muaj cov cuab yeej tshwj xeeb ntawm lub cev: tiv thaiv gamma rays. Qhov ntawd yog hais tias, yog tias siv rau cov khoom kho mob, gamma rays tuaj yeem siv ncaj qha rau kev tua kab mob yam tsis muaj kev puas tsuaj rau lawv lub cev thiab qhov ruaj khov, uas yog cov khoom siv lub cev uas polypropylene (PP) spunbond non-woven fabrics tsis muaj.

Polypropylene non-woven npuag

Spunbonded non-woven npuag yog hais txog qhov nruam filament tsim los ntawm extrusion thiab stretching ntawm polymers, uas yog nteg rau hauv lub web. Lub vev xaib yog tom qab ntawd nws tus kheej sib txuas, thermally bonded, chemically bonded lossis mechanically reinforced los tig lub vev xaib mus rau hauv cov ntaub ntawv tsis-woven.Siv rau cov khoom siv tu cev, xws li cov ntaub so ntswg, lub tsho phais, kaus mom, lub qhov ncauj qhov ntswg, ntaub pua chaw pw, ntaub pawm, thiab lwm yam. Cov poj niam cov ntaub so ntswg huv, cov khoom siv niaj hnub siv tau rau cov menyuam yaus thiab cov neeg laus.

Tsis-woven polypropylene vs polyester

PP yog polypropylene raw khoom, uas yog polypropylene fiber, uas belongs rau nyias non-woven npuag; PET yog hom tshiab polyester raw khoom, uas yog polyester fiber, tsis muaj additives nyob rau hauv tag nrho cov txheej txheem ntau lawm. Nws yog ib yam khoom zoo heev rau ib puag ncig thiab belongs rau cov ntaub uas tsis yog-woven.

Qhov sib txawv ntawm polypropylene thiab polyester fibers

1 、 Cov txheej txheem tsim khoom

Cov qauv tsim ntawm polypropylene thiab polyester fibers txawv. Polypropylene yog npaj los ntawm cua sov propylene monomers rau qhov kub thiab txias thiab ntxiv rau cov catalyst rau polymerization, thaum polyester fibers tau ua tiav rau hauv cov ntaub ntawv fiber ntau los ntawm kev ntxiv cellulose etherification agents thiab cov kuab tshuaj rau polyester resin.

2 、 Cov yam ntxwv ntawm cov khoom

1. Hais txog lub cev muaj zog:

Polypropylene yog lub teeb yuag thiab muaj fiber ntau lub zog, tab sis nws hnav tsis kam thiab kub tsis kam yog qhov tsis zoo. Polyester fibers muaj lub zog tensile siab thiab kav ntev, nrog rau cov cua sov thiab tshuaj tiv thaiv, ua rau lub neej ua haujlwm ntev.

2. Hais txog cov khoom siv tshuaj lom neeg:

Polypropylene muaj cov tshuaj lom neeg ruaj khov, tsis yooj yim corroded los ntawm acids, alkalis, thiab lwm yam, thiab tsis muaj tshuaj lom thiab tsis zoo. Polyester fiber ntau muaj benzene nplhaib qauv thiab muaj qee qhov kev tiv thaiv corrosion.

3. Hais txog ib puag ncig tus phooj ywg:

Polypropylene yog cov khoom siv thermoplastic uas tsis yooj yim biodegradable thiab ua paug rau ib puag ncig. Polyester fibers tuaj yeem degraded los ntawm cov kab mob thiab yuav tsis ua rau muaj kuab paug rau ib puag ncig.

Qhov txawv ntawm PP non-woven npuag thiabPET non-woven npuag

1. PP raw khoom pheej yig, thaum PET raw khoom kim heev. PP cov khib nyiab tuaj yeem rov ua dua hauv qhov cub, thaum PET pov tseg tsis tuaj yeem rov ua dua, yog li tus nqi ntawm PP qis dua me ntsis.

2. PP muaj qhov kub tsis kam ntawm ib puag ncig 200 degrees, thaum PET muaj qhov kub tsis kam ntawm ib puag ncig 290 degrees. PET tiv taus kub ntau dua li PP.

3. Cov ntaub ntawv uas tsis yog woven luam ntawv, cov nyhuv hloov tshav kub, tib qhov dav PP shrinks ntau, PET shrinks tsawg, muaj cov nyhuv zoo dua, PET txuag ntau dua thiab pov tseg tsawg dua.

4. Tensile force, nro, load-bearing muaj peev xwm, thiab qhov hnyav tib yam, PET muaj zog tensile ntau dua, nro, thiab load-bearing muaj peev xwm tshaj PP. 65 grams ntawm PET yog sib npaug rau 80 grams ntawm PP nyob rau hauv cov nqe lus ntawm nro, nro, thiab load-bearing muaj peev xwm.

5. Los ntawm ib puag ncig kev xav, PP yog tov nrog PP pov tseg, thiab tag nrho cov PET chips yog brand tshiab. PET yog ib puag ncig tus phooj ywg thiab tu cev ntau dua li PP.
