Dab tsi yog cov khoom siv spunbond

Muaj ntau ntau hom non-woven fabrics, thiab spunbond non-woven fabrics yog ib qho ntawm lawv. Cov ntaub ntawv tseem ceeb ntawm spunbond non-woven npuag yog polyester thiab polypropylene, nrog lub zog siab thiab zoo kub-resistant. Hauv qab no, lub rooj nthuav qhia tsis-woven npuag yuav qhia rau koj tias dab tsi yog spunbond non-woven npuag? spunbond khoom yog dab tsi? Cia peb saib ua ke.

Dab tsi yogtxoj kev spunbond

Qhov laj thawj tseem ceeb rau nws txoj kev loj hlob sai yog tias nws siv cov khoom siv hluavtaws ua cov khoom siv raw. Txoj kev no siv lub hauv paus ntsiab lus ntawm cov tshuaj fiber ntau spinning kom tsis tu ncua filament thaum lub sij hawm polymer spinning txheej txheem, uas yog ces sprayed rau hauv lub web thiab ncaj qha sib txuas los tsim cov ntaub tsis-woven. Txoj kev tsim khoom yog yooj yim heev thiab ceev. Piv nrog rau cov tshuab ziab khaub ncaws tsis-woven, nws tshem tawm cov txheej txheem ntawm cov txheej txheem nruab nrab xws li fiber ntau curling, txiav, ntim, tsheb thauj mus los, sib tov, thiab combing Cov txiaj ntsig tseem ceeb tshaj plaws ntawm cov khoom loj yog ua kom cov khoom siv spunbond muaj zog, tsis tshua muaj nqi, thiab ruaj khov zoo. Txoj kev ncab ntawm txoj kev spunbond yog qhov teeb meem tseem ceeb rau kev tau txais cov khoom zoo denier thiab cov ntaub ntawv tsis muaj zog, thiab tam sim no txoj kev tseem ceeb yog huab cua ntws stretching tshuab. Txhawm rau txhawm rau txhim kho cov cua ntsawj ntshab ntawm spunbond fibers, kev ua haujlwm siab extrusion ntawm ib lub qhov spinning, tsim cov high-density spinneret qhov, thiab lawv cov kev cuam tshuam rau kev tsim thiab zoo ntawm cov ntaub ntawv uas tsis yog-woven, peb tab tom kawm tsim qauv ntawm cov cua ntsawj ntshab channel combining zoo siab thiab tsis zoo siab, raws li zoo raws li qhov cuam tshuam ntawm electrostatic spinning ntawm spinning ceev, web dav, zoo web uniformity. Qhov no yog ib hom tshwj xeeb ntawm cov khoom siv spunbond tsim los rau kev lag luam, Ib qho ntawm cov haujlwm tseem ceeb ntawm cov khoom siv spunbond ob qho tib si.

Dab tsi yog cov khoom siv spunbond

Cov khoom siv raw rauspunbond non-woven fabricsFeem ntau suav nrog cellulose fibers thiab hluavtaws fibers, uas yog tsim los ntawm cov txheej txheem spunbond. Nws muaj tes zoo, breathability, thiab hnav tsis kam, thiab yog dav siv nyob rau hauv ntau yam teb. Cov txheej txheem tsim khoom ntawm spunbond non-woven npuag yog yooj yim, raug nqi, thiab muaj kev lag luam dav dav. Nws cia siab tias yuav muaj kev tsim kho tshiab thiab kev loj hlob ntxiv rau yav tom ntej, yog li ntawd spunbond non-woven npuag tuaj yeem ua lub luag haujlwm ntau dua hauv ntau yam.

Cellulose fiber ntau

Cellulose fiber yog ib qho tseem ceeb raw khoom rau kev tsim spunbond non-woven fabrics. Cellulose yog ib qho organic tebchaw uas muaj nyob rau hauv cov nroj tsuag cell phab ntsa. Ntau cov nroj tsuag fibers, xws li paj rwb, linen, hemp, thiab lwm yam, muaj ntau cellulose. Cov nroj tsuag no tau siv ntau txoj kev kho mob, xws li tev, tshem tawm, thiab boiling, kom tshem tawm cellulose los ntawm cov nroj tsuag. Tom qab ntawd, los ntawm cov txheej txheem spunbond, cov cellulose fibers tau ncab thiab taw qhia los tsim cov ntaub spunbond tsis-woven. Cellulose fibers muaj softness thiab breathability, ua spunbond non-woven fabrics muaj tes zoo thiab breathability.

Synthetic fibers

Synthetic fibers yog lwm cov khoom siv raw rau spunbond non-woven fabrics. Synthetic fibers yog cov fibers uas tsim los ntawm cov khoom siv dag zog los yog kev hloov kho tshuaj, xws li polyester fibers, nylon fibers, thiab lwm yam. Synthetic fibers muaj cov khoom zoo heev ntawm lub cev thiab tshuaj stability, thiab cov yam ntxwv ntawm cov fibers tuaj yeem hloov kho raws li qhov xav tau. Hauv kev tsim cov txheej txheem ntawm spunbond non-woven fabrics, hluavtaws fibers feem ntau yog tov nrog cellulose fibers los txhim kho lub zog thiab hnav tsis kam ntawm spunbond non-woven fabrics.

Dab tsi yog spunbond non-woven npuag?

Spunbonded non-woven npuag, feem ntau yog ua los ntawm polyester thiab polypropylene, muaj lub zog siab thiab zoo kub-resistant. Spunbonded non-woven npuag extrudes thiab stretches polymers los ua nruam filaments, uas yog ces muab tso rau hauv ib lub web. 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.

Kev xaiv cov khoom siv raw

Cov khoom siv raw siv nyob rau hauv cov kab ntau lawm muaj feem xyuam nrog kev ua lag luam thiab lub hom phiaj ntawm cov khoom. Thaum tsim cov khoom lag luam qis qis, vim tias qhov kev xav tau tsawg rau cov khoom siv raw, txhawm rau txo cov nqi tsim khoom, cov khoom siv qis qis tuaj yeem xaiv tau. Qhov ntxeev kuj muaj tseeb.

Feem ntau cov spunbond nonwoven cov kab ntau lawm siv granular polypropylene (PP) chips ua raw khoom, tab sis kuj tseem muaj ob peb kab me me uas siv cov hmoov PP raw cov ntaub ntawv, thiab qee cov kab ntau lawm uas siv cov khoom siv raw polypropylene. Ntxiv nrog rau cov ntaub ntawv raw khoom, yaj cov tshuab tsis-woven cov kab ntau lawm kuj tseem siv cov ntaub ntawv raw khoom.

Tus nqi ntawm slicing yog ncaj qha ntsig txog qhov loj ntawm nws tus nqi MFI, feem ntau qhov loj dua tus nqi MFl, tus nqi siab dua. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog cov txheej txheem tsim khoom, cov yam ntxwv ntawm cov khoom siv, cov khoom siv, cov khoom muag, tus nqi tsim khoom, thiab lwm yam los xaiv cov khoom siv raw.
