Hauv cov ntaub ntawv fiber ntau, viscose fiber ntau tau nyiam ntau dua rau nws cov khoom lag luam thiab cov khoom siv dav dav thiab cov khoom siv dav dav thiab cov khoom siv dav dav, thiab cov khoom siv dav dav thiab cov cuab yeej siv dav dav yog cov thev naus laus zis hauv kev lag luam.
Cov moulding ntawm viscose fiber pib nrog kev npaj ntawm viscose tov. Xaiv cov khoom siv cellulose zoo nkauj heev, tom qab kev kho mob thiab kev siv tshuab, ua rau muaj kev daws teeb meem viscose. Cov txheej txheem no tau ua kom nruj ntawm txoj kev xav, viscosity thiab lwm yam yuav tsum tau ua kom meej meej tswj tau kom muaj kev sib tw tom qab.
Kev tshem tawm ntawm kev daws los ntawm lub nozzle yog kauj ruam tseem ceeb. Tus tsim ntawm lub nozzle yog qhov tseem ceeb heev, thiab nws qhov cuam tshuam rau cov kev sib txuam thiab kev lom zem ntawm cov fiber. Thaum lub sijhawm ua haujlwm extrusion yog extruded los ntawm lub qhov me me ntawm lub nozzle nyob rau hauv cov kev mob ib puag ncig thiab cov av noo, thiab lub sijhawm ntev.
Cov txheej txheem kev sib cais ua raws. Filament nkag mus hauv chav da dej sib xyaw, qhov twg daws qhov datused sai thiab cov cellulose maj mam pib, sib sau cov qauv theem pib ntawm cov khoom siv fiber ntau. Qhov muaj pes tsawg leeg thiab cov concentration ntawm lub sib xyaw ua ke da dej ncaj ncaj cuam tshuam qhov zoo ntawm cov fiber thiab yuav tsum tau tsim qauv nruj thiab saib xyuas.
Tom qab sau ntawv txuas mus tom ntej yuav tsum tsis txhob raug underestimated. Los ntawm kev sau ntawv kom raug, kev taw qhia thiab crystallinity ntawm cov fiber ntau tuaj yeem txhim kho, yog li kev txhim kho lub zog thiab elasticity ntawm cov fiber. Qhov tsim qauv ntau qhov xav tau los ua kom raug teeb tsa raws li cov khoom lag luam sib txawv.
Txhawm rau txhim kho kev ua tau zoo ntawm cov fiber ntau dhau, kev ua haujlwm tom qab yog qhov tseem ceeb. Dyeing, tiav thiab lwm yam haujlwm muab viscers ntau zog, tau ntsib cov kev xav tau tshwj xeeb ntawm cov khoom muaj ntau lub teb.
Txhua qhov txuas hauv viscose fiber ntau cov txheej txheem yog txuas ze thiab ua kom tiav. Nrog kev tsim kho cov thev naus laus zis, cov qauv viscing fiber ntau ntxiv rau yav tom ntej, thiab nws yuav ua rau kev txhawb nqa zoo rau kev txhawb nqa kev lag luam ntawm kev lag luam ntsig txog kev lag luam.
