Spunbond polypropylene ntaub

Oue spunbond nonwoven fabric yog ib hom nonwoven textile ua los ntawm thermoplastic polypropylene (PP) fibers uas yog sib koom ua ke los ntawm cov txheej txheem thermal. Cov txheej txheem cuam tshuam nrog extruding PP fibers, uas yog ces spun thiab nteg nyob rau hauv ib tug random qauv los tsim ib lub web. Lub vev xaib yog tom qab ntawd sib koom ua ke los tsim cov ntaub muaj zog thiab ruaj khov.

Cov yam ntxwv ntawm PP spun bond non woven npuag

Polypropylene spunbond non-woven npuag muaj cov yam ntxwv ntawm lub teeb yuag, breathability, durability, waterproofing, anti-static, thiab ib puag ncig tiv thaiv.Polypropylene spunbond non-woven npuag yog ib qho khoom siv hnyav nrog cov yam ntxwv ntawm lub teeb yuag thiab muaj zog load-bearing muaj peev xwm. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws, haum rau ntau qhov chaw xws li kev kho mob, khoom siv hauv tsev, thiab lwm yam. Meanwhile, vim nws lub teeb, nws kuj yooj yim dua rau nqa thiab nruab.

pp spunbond tsis woven ntaub siv

PP spunbond nonwoven npuag muaj ntau yam kev siv thoob plaws kev ua liaj ua teb, kev tsim kho, ntim khoom, geotextiles, tsheb, khoom vaj khoom tsev. Spunbonded nonwoven npuag yog ib yam khoom uas muaj peev xwm txhim kho, uas siv tag nrho cov txiaj ntsig ntawm fibers ua cov ntaub ntawv kho mob. Nws yog ib yam khoom ntawm kev qhuab qhia kev lag luam uas tshwm sim los ntawm kev sib koom ua ke thiab kev sib tshuam ntawm ntau yam kev qhuab qhia thiab thev naus laus zis. Qhov no suav nrog cov ris tsho phais, cov khaub ncaws tiv thaiv, hnab tshuaj tua kab mob, lub qhov ncauj qhov ntswg, cov pawm, cov ntaub hauv tsev, cov ntaub so ntswg, cov ntaub so ntswg, cov phuam so tes, cov ntaub so ntswg, cov khoom siv zoo nkauj, cov ntaub so ntswg huv, thiab cov ntaub so huv uas siv tau.

Nkag siab txog cov txheej txheem spin bonding

Cov txheej txheem ntawm spunbonding, siv los ua cov ntaub nonwoven, entails extruding thermoplastic polymers, feem ntau polypropylene (PP), rau hauv filaments tas mus li. Tom qab ntawd, cov filaments yog teem rau hauv ib lub web zoo thiab fused ua ke kom ib tug robust, ntev ntaub. Ntau yam kev ntshaw, xws li lub zog siab, ua pa, dej tsis kam, thiab tshuaj lom neeg, muaj nyob rau hauv qhov ua rau PP spunbond nonwoven fabric. Nov yog cov lus piav qhia ntxaws txog txheej txheem spunbonding:

1. Extrusion ntawm polymers: Extrusion ntawm lub polymer ntawm ib tug spinneret, feem ntau nyob rau hauv daim ntawv ntawm pellets, yog thawj kauj ruam nyob rau hauv tus txheej txheem. Lub molten polymer yog tsav nyob rau hauv siab los ntawm lub spinneret ntau lub qhov me me.

2. Filament spinning: Lub polymer yog stretched thiab txias raws li nws tawm ntawm spinneret los tsim filaments uas txuas mus ntxiv. Feem ntau, cov filaments no muaj txoj kab uas hla ntawm 15-35 microns.

3. Kev tsim lub vev xaib: Txhawm rau tsim lub vev xaib, cov filaments tau muab sib sau ua ke nyob rau hauv ib qho kev txiav txim siab ntawm kev txav conveyor siv los yog nruas. Qhov hnyav ntawm lub vev xaib feem ntau yog 15-150 g / m².

4. Kev sib khi: Txhawm rau khi cov filaments ua ke, lub vev xaib tom qab raug tshav kub, siab, lossis tshuaj lom neeg. Ntau cov tswv yim, xws li kev sib txuas ntawm cov cua sov, kev sib txuas tshuaj, lossis kev siv tshuab, tuaj yeem siv los ua kom tiav qhov no.

5. Kev ua tiav: Tom qab kev sib txuas, cov ntaub feem ntau yog calendered lossis muab ib qho tiav los txhim kho nws cov yam ntxwv ua tau zoo, xws li dej tsis kam, UV tsis kam.
