Dab tsi yog Spunmelt Nonwoven
Jul 18, 2024
Spunmeltnonwovensyog cov ntaub tshwj xeeb uas sib xyaw ua ke zoo tshaj plaws ntawm ob qho tib si spunbond thiab meltblown technologies. Cov ntaub pib nrog nruam polymer filaments uas yog thawj rhuab thiab melted, ces precisely extruded thiab stretched, thiab nteg nyob rau hauv ib tug random los yog preset qauv los tsim ib tug ua ntej mesh qauv. Txhawm rau txhim kho cov ntaub ntawv kev ncaj ncees, lub mesh yog tom qab sib txuas los ntawm thermal, tshuaj lossis cov cuab yeej siv los tsim ib daim ntaub tawv.
Tshwj xeeb, cov txheej txheem spunbond suav nrog kev hloov cov molten polymer hais los ntawm spinneret mus rau hauv cov filaments txuas ntxiv uas tau txias, ncab, nteg rau ntawm cov cab kuj mus rau hauv lub hauv paus mesh txheej, thiab ntxiv dag zog los ntawm thermal bonding technology los muab cov ntaub zoo heev zog thiab tensile zog.
Cov txheej txheem meltblown mus ib kauj ruam ntxiv thiab txau cov molten polymer los ntawm ib lub me me nozzle rau hauv cov cua kub ceev ntawm kev kub ceev, tam sim ntawd tawg mus rau hauv ultra-fine microfibers uas maj mam tso rau ntawm ib qho khoom siv los tsim cov mos mos, nplua-fiber. mesh. Meltblown fabrics tau ua kom pom kev ua tau zoo hauv kev pom nrog lawv cov qauv fiber ntau thiab thaj chaw loj.
Thaum spunbond thiab meltblown technologies sib ntxiv thiab ua hauj lwm ua ke nyob rau hauv zus tau tej cov non-woven fabrics, spunmelt non-woven fabrics tau yug los. Nws cleverly combines lub zog ntawm spunbond fabrics nrog lub softness thiab delicacy ntawm meltblown fabrics, uas tsis tsuas yog xyuas kom meej lub durability ntawm cov ntaub ntawv tab sis kuj muab nws zoo heev mos kov thiab filtering muaj peev xwm. Yog li ntawd, spunmelt non-woven fabrics yog dav siv nyob rau hauv kev tiv thaiv kev kho mob (surgical gowns, lub qhov ncauj qhov ntswg, thiab lwm yam), kev tu tus kheej (diapers, huv si napkins) thiab industrial teb (filters, rwb thaiv tsev ntaub ntawv, thiab lwm yam), los ua ib tug indispensable thiab tseem ceeb cov ntaub ntawv. hauv ntau thaj chaw.
