Tsis woven hnab raw khoom

Cov khoom siv raw rau cov hnab tsis-woven

Cov hnab tsis woven yog ua los ntawm cov ntaub tsis-woven raws li cov khoom siv raw. Non-woven fabric yog ib tiam tshiab ntawm ib puag ncig cov ntaub ntawv uas muaj dej-pov thawj, breathable, saj zawg zog, hnav, tsis combustible, yooj yim rau decompose, tsis muaj tshuaj lom thiab tsis irritating, nplua nuj xim, tsis tshua muaj nqi, thiab recyclable. Cov khoom no tuaj yeem decompose lawm tom qab muab tso rau sab nraum zoov rau 90 hnub, thiab muaj kev pabcuam lub neej txog li 5 xyoos thaum muab tso rau hauv tsev. Thaum hlawv, nws tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis muaj cov khoom seem, yog li tsis ua phem rau ib puag ncig. Nws yog thoob ntiaj teb lees paub tias yog ib qho khoom noj khoom haus zoo rau kev tiv thaiv lub ntiaj teb ecology.

Muaj ob lub ntsiab raw khoom rau cov hnab tsis-woven, ib qho yog polypropylene (PP), thiab lwm yam yog polyethylene terephthalate (PET). Ob leeg ntawm cov ntaub ntawv no yog ib hom ntaub ntawv uas tsis yog-woven, tsim los ntawm fibers los ntawm thermal bonding los yog mechanical reinforcement, muaj zog thiab zoo waterproof.

Polypropylene (PP): Qhov no yog ib qhonon-woven ntaub ntaubnrog zoo lub teeb tsis kam, corrosion kuj, thiab tensile zog. Vim nws cov qauv asymmetric thiab yooj yim aging thiab sib txawv, cov hnab tsis-woven tuaj yeem oxidized thiab decomposed hauv 90 hnub.

Polyethylene terephthalate (PET): tseem hu ua polyester, cov khoom siv no lub hnab tsis-woven yog sib npaug, tab sis piv rau polypropylene, nws cov nqi ntau dua.

Kev faib tawm ntawm cov hnab tsis-woven

1. Cov khoom tseem ceeb ntawm cov hnab tsis-woven yog non-woven npuag. Non-woven fabric yog ib hom non-woven npuag uas yog ib yam tshiab ntawm cov khoom siv fiber ntau nrog cov mos mos, breathable, thiab tiaj tus qauv tsim los ntawm ncaj qha siv high polymer chips, luv fibers, los yog ntev fibers los ntawm ntau yam fiber ntau mesh txoj kev thiab kev sib koom ua ke. Qhov zoo: Cov hnab tsis woven yog tus nqi-zoo, ib puag ncig tus phooj ywg thiab siv tau, dav siv, thiab muaj cov haujlwm tshaj tawm. Haum rau ntau yam kev ua lag luam thiab kev nthuav qhia, nws yog qhov khoom plig tshaj tawm tshaj tawm zoo tshaj plaws rau cov lag luam thiab cov tsev kawm

2. Cov khoom siv raw rau cov ntaub tsis-woven yog polypropylene, thaum cov khoom siv raw rau cov hnab yas yog polyethylene. Txawm hais tias ob yam khoom muaj npe zoo sib xws, lawv cov qauv tshuaj nyob deb sib nrug. Cov qauv tshuaj molecular ntawm polyethylene muaj qhov ruaj khov thiab nyuaj rau degrade, yog li cov hnab yas siv sijhawm 300 xyoo los ua kom tiav; Txawm li cas los xij, cov qauv tshuaj ntawm polypropylene tsis muaj zog, thiab cov saw hlau molecular tuaj yeem tawg tau yooj yim, uas tuaj yeem txo qis thiab nkag mus rau lub voj voog ib puag ncig tom ntej hauv daim ntawv tsis muaj tshuaj lom. Ib lub hnab tsis-woven tuaj yeem decomposed tag nrho hauv 90 hnub.

Raws li cov txheej txheem ntau lawm, nws tuaj yeem muab faib ua

1. Spinning: Nws yog cov txheej txheem ntawm kev txau cov dej siab zoo rau ib lossis ntau txheej ntawm fiber ntau mesh, ua rau cov fibers sib cuam tshuam thiab ntxiv dag zog rau cov mesh kom muaj zog.

2. Thaum tshav kub kub kaw tsis-woven hnab: yog hais txog kev ntxiv fiber ntau los yog hmoov kub yaj nplaum nplaum rau cov ntaub fiber ntau, thiab tom qab ntawd cua sov, yaj, thiab txias cov fiber ntau mesh los txhawb rau hauv daim ntaub.

3. Pulp airflow net non-woven fabric bag: tseem hu ua daim ntawv tsis muaj plua plav lossis qhuav papermaking non-woven fabric. Nws siv airflow mesh thev naus laus zis los loosen cov ntoo pulp fiberboard rau hauv ib lub xeev fiber ntau, thiab tom qab ntawd siv cov txheej txheem airflow los sib sau cov fibers ntawm cov ntaub thaiv npog, thiab cov fiber ntau mesh yog ntxiv dag zog. 4. Lub hnab ntim tsis-woven npuag: Nws yog txheej txheem ntawm loosening fiber ntau cov ntaub ntawv uas muab tso rau hauv ib qho dej nruab nrab rau hauv ib fibers, thiab sib tov sib txawv fiber ntau raw cov ntaub ntawv los tsim fiber ntau suspension slurry. Lub slurry raug tshem tawm yog thauj mus rau lub web tsim mechanism, thiab cov fibers tau ntxiv rau hauv daim ntaub ntub dej.

5. Spin bonded non-woven npuaghnab: Nws yog txheej txheem uas cov polymer tau raug extruded thiab ncab los ua ib qho txuas txuas ntxiv, uas tom qab ntawd muab tso rau hauv lub vev xaib. Lub vev xaib yog tom qab ntawd nws tus kheej sib raug zoo, thermally bonded, chemically bonded, los yog mechanically reinforced los hloov mus rau hauv cov ntaub tsis-woven.

6. Melt blown non-woven fabric bag: Nws cov txheej txheem muaj xws li polymer pub - yaj extrusion - fiber ntau tsim - fiber ntau txias - mesh tsim - reinforcement rau hauv ntaub.

7. Acupuncture: Nws yog ib hom qhuav tsis-woven npuag uas siv cov nyhuv puncture ntawm ib rab koob los txhawb lub fluffy fiber mesh rau hauv ntaub.

8. Stitch weaving: Nws yog ib yam ntawm cov txheej txheem qhuav uas tsis yog-woven npuag uas siv warp knitted coil qauv los weave fibers, yarn txheej, cov ntaub ntawv tsis-woven (xws li cov ntawv yas, yas nyias hlau foils, thiab lwm yam) los yog lawv pawg.
