Yuav Ua Li Cas Paub Txog Cov Txheej Txheem Thiab Feem Ntawm Ib Ntu Ntawm Cov Npuag Tsis-Woven?

Non-woven fabrics, tseem hu ua non-woven fabrics, yog tsim los ntawm kev taw qhia los yog random fibers. Lawv yog cov tiam tshiab ntawm cov ntaub ntawv zoo ib puag ncig. Lawv yog cov dej-pov thawj, breathable, saj zawg zog, lub teeb nyob rau hauv qhov hnyav, tsis-combustible, yooj yim rau decompose, tsis muaj tshuaj lom thiab tsis ua rau khaus, nplua nuj xim, thiab pheej yig. Pheej yig thiab recyclable.

Piv txwv li, polypropylene (pp khoom) pellets yog siv los ua raw cov ntaub ntawv thiab yog tsim los ntawm ib tug tas mus li txoj kev ntawm high-temperature melting, spinning, nteg, thiab kub nias thiab coiling.

Nws yog hu ua daim ntaub vim nws qhov tsos thiab qee yam khoom.

Nws yog ua los ntawm polypropylene spun ncaj qha mus rau hauv ib lub mesh thiab thermally bonded. Lub zog ntawm cov khoom yog zoo dua li cov khoom siv fiber ntau zoo tib yam. Lub zog tsis yog kev taw qhia, thiab lub zog ntsug thiab kab rov tav zoo sib xws.

Hais txog kev tiv thaiv ib puag ncig, cov khoom siv raw ntawm feem ntau ntawm cov ntaub tsis-woven tam sim no yog polypropylene, thaum cov khoom siv ntawm cov hnab yas yog polyethylene. Txawm hais tias ob yam khoom muaj npe zoo sib xws, lawv txawv heev hauv cov qauv tshuaj.

Cov qauv tshuaj molecular ntawm polyethylene yog qhov ruaj khov thiab nyuaj rau degrade, yog li nws yuav siv sij hawm 300 xyoo rau cov hnab yas kom decompose; Thaum cov qauv tshuaj ntawm polypropylene tsis muaj zog, cov saw hlau molecular tuaj yeem tawg tau yooj yim, kom nws tuaj yeem degraded zoo, thiab nkag mus rau lub voj voog ib puag ncig tom ntej hauv daim ntawv tsis muaj tshuaj lom, lub hnab ntim khoom tsis-woven tuaj yeem decomposed tag nrho hauv 90 noj.

Thiab cov hnab ntim khoom tsis-woven tuaj yeem rov qab siv ntau dua 10 zaug, thiab cov pa phem rau ib puag ncig tom qab pov tseg tsuas yog 10 feem pua ​​​​ntawm cov hnab yas.

Cov fibers siv nyob rau hauv kev tsim cov ntaub tsis-woven yog tsuas yog polypropylene (PP) thiab polyester (PET). Tsis tas li ntawd, muaj nylon (PA), viscose, acrylic, ethylene (HDPE), thiab yas (PVC). Raws li daim ntawv thov yuav tsum tau, cov ntaub uas tsis yog-woven yog muab faib ua ob pawg: cov ntaub ntawv pov tseg thiab hom siv tau ntev.

Tam sim no, cov txiv neej ua fibers tseem ua tus thawj coj ntawm cov khoom siv nonwovens, thiab ua ntej xyoo 2007, qhov xwm txheej no yuav tsis hloov pauv ntau. 63 feem pua ​​​​ntawm cov fibers siv hauv kev tsim cov nonwovens thoob ntiaj teb yog polypropylene, 23 feem pua ​​​​polyester, 8 feem pua ​​​​viscose, 2 feem pua ​​acrylic, 1.5 feem pua ​​​​polyamide thiab 3 feem pua ​​​​yog lwm cov fibers.
