Nonwoven ntaubyog ib hom ntawm cov khoom uas yog tsim los ntawm kev sib txuas los yog interlocking fibers ua ke tsis muaj weaving los yog knitting. Cov txheej txheem no tsim cov ntaub uas muaj zog, ruaj, thiab ntau yam, ua rau nws haum rau ntau yam kev siv. Ib qho ntawm cov khoom tseem ceeb hauv kev tsim cov ntaub nonwoven yog rab koob, uas ua lub luag haujlwm tseem ceeb hauv kev tsim khoom.
Koob siv nyob rau hauv zus tau tej cov nonwoven ntaub yog tshwj xeeb tsim los interlace los yog entangle lub fibers los ua ib tug cohesive web. Cov koob no feem ntau yog ua los ntawm cov hlau zoo thiab tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg kom haum rau ntau hom fibers thiab ntau txoj kev. Tus tsim ntawm rab koob, nrog rau nws cov duab, ntsuas, thiab barb configuration, yog ua tib zoo tsim kom ua tiav cov ntaub ntawv tshwj xeeb xws li lub zog, ntom, thiab kev ntxhib los mos.
Lub koob punching txheej txheem, tseem hu ua rab koob felting, yog ib txoj hauv kev siv los tsim cov ntaub nonwoven. Thaum lub sij hawm tus txheej txheem no, cov fibers tau pub rau hauv lub tshuab uas lawv dhau los ntawm ntau cov koob uas xuas nrig ntaus lawv ntau zaus, ua rau cov fibers cuam tshuam thiab tsim lub vev xaib sib txuas. Qhov ceev thiab lub zog ntawm cov ntaub tuaj yeem tswj tau los ntawm kev kho cov koob ceev, qhov tob tob, thiab xuas nrig ntaus zaus.
Cov txheej txheem rab koob punching yog ntau yam thiab tuaj yeem siv nrog ntau hom fibers, nrog rau cov fibers ntuj xws li paj rwb thiab ntaub plaub, nrog rau cov khoom siv hluavtaws xws li polyester thiab polypropylene. Qhov no versatility ua rau koob-punched nonwoven ntaub haum rau ntau yam kev siv, nrog rau pom, geotextiles, automotive interiors, thiab rwb thaiv tsev.
Ntxiv nrog rau rab koob punching, koob kuj tseem siv rau hauv lwm txoj kev tsim cov ntaub tsis muaj ntaub xws li spunbonding thiab meltblowing. Nyob rau hauv spunbonding, nruam filaments yog extruded thiab nteg mus rau ib tug txav txoj siv, thiab ces sib txuas ua ke siv ib tug ua ke ntawm tshav kub, siab, thiab koob. Meltblowing cuam tshuam nrog extruding molten polymer los ntawm cov txheej txheem zoo nozzles thiab tom qab ntawd siv cov cua nrawm kom txo qis cov fibers ua ntej lawv tau sau rau ntawm txoj siv conveyor thiab sib koom ua ke siv cov koob.
Kev tsim thiab kev tsim kho ntawm cov koob siv hauv cov ntaub ntawv tsis-woven yog qhov tseem ceeb rau qhov zoo thiab kev ua tau zoo ntawm cov ntaub uas tshwm sim. Cov duab thiab kev teeb tsa ntawm rab koob barbs, nrog rau qhov sib nrug thiab kev sib dhos ntawm cov koob, tuaj yeem cuam tshuam rau cov khoom ntawm cov ntaub, xws li tensile zog, abrasion resistance, thiab porosity.
Tsis tas li ntawd, kev xaiv ntawm rab koob hom thiab qhov loj me yog cuam tshuam los ntawm cov kev cai tshwj xeeb ntawm cov ntaub nonwoven raug tsim. Piv txwv li, cov koob zoo dua tuaj yeem siv rau cov ntaub hnyav, thaum cov koob coarser haum rau cov ntaub hnyav dua thiab muaj zog dua.
Hauv kev xaus, koob ua lub luag haujlwm tseem ceeb hauv kev tsim cov ntaub tsis-woven, tshwj xeeb hauv cov txheej txheem xws li rab koob punching, spunbonding, thiab meltblowing. Kev tsim thiab kev tsim kho ntawm cov koob no tau ua tib zoo tsim kom ua tiav cov ntaub ntawv tshwj xeeb, ua rau lawv cov khoom tseem ceeb hauv kev tsim cov khoom zoo tsis zoo rau ntau yam kev siv.
