Melt-spinning yog txoj kev spinning tshaj plaws rau hluavtaws fibers los ntawm thermoplastic polymers xws li polyamide thiab polyester. Cov txheej txheem cuam tshuam nrog melting polymer chips thiab extruding nws mus rau hauv zoo heev filaments los ntawm me me orifices ntawm lub phaj hu ua spinneret.
Hauv qhov no, cov khoom siv hluavtaws ua li cas?
Synthetic fiber ntau . Feem ntau, hluavtaws fibers yog tsim los ntawm extruding fiber ntau -forming cov ntaub ntawv los ntawm spinnerets, ua ib fiber ntau . Cov no hu ua hluavtaws los yog Artificial fibers . Synthetic fibers yog tsim los ntawm cov txheej txheem hu ua polymerization, uas koom nrog kev sib txuas ntawm cov monomers los ua cov saw ntev los yog polymer.
Qhov thib ob, cov cuab yeej siv dab tsi hauv cov txheej txheem ntawm extruding polymer kua thaum lub sij hawm tsim fibers? Ib tug spinneret yog ib khoom siv rau extrude ib polymer daws los yog polymer yaj rau daim ntawv fibers . Cov dej khov polymer tawm ntawm lub spinneret rau hauv huab cua los yog kua ua rau ib theem inversion uas tso cai rau cov polymer kom khov. Tus kheej polymer chains nyiam dlhos nyob rau hauv lub fiber ntau vim dej khov.
Tsis tas li ntawd, cov peev txheej dab tsi yog siv los ua hluavtaws fiber ntau?
Synthetic fibers yog tsim los ntawm cov ntaub ntawv cog thiab minerals: viscose los ntawm ntoo thuv lossis petrochemicals, thaum acrylic, nylon thiab polyester los ntawm roj thiab thee. Viscose fiber ntau yog tau los ntawm cellulose; versatility tso cai rau xyaum cov ntaub ntawv xws li paj rwb los yog txhob lo lo ntxhuav.
Dab tsi yog hluavtaws fibers siv rau?
Cov no hluavtaws staple fibers feem ntau siv rau tsim cov ntaub ntawv nrov nonwoven xws li polyester, polypropylene, nylon, thiab Kevlar ™. Tab sis thaum hluavtaws fibers tuaj yeem ua rau txhua txoj kab uas hla (denier) mus txog qhov taw tes-tsuas yog los ntawm kev hloov txoj kab uas hla ntawm lub qhov-paj rwb txoj kab uas hla tsis ntsuas hauv denier.

Ntev npaum li cas cov roj hluavtaws hluavtaws ntev ntev?
Tswb hais tias nrog cov roj hluavtaws thiab qee cov tuam txhab tsim khoom, lub sijhawm nruab nrab ntawm cov roj hloov tuaj yeem ua tau ntau, ntev dua: 'Qee zaum ntau li 15,000 mais lossis ib xyoos.' Qee tus kws kho tsheb, txawm li cas los xij, hais tias koj yuav tsum hloov koj cov roj txhua 5,000 mais txawm tias muaj roj hluavtaws
Kuv puas tuaj yeem siv cov roj hluavtaws tag nrho es tsis txhob siv hluavtaws sib xyaw?
Koj tuaj yeem hloov rov qab mus rau txhua lub sijhawm. Qhov tseeb, cov khoom siv hluavtaws tsuas yog sib xyaw ntawm cov roj hluavtaws thiab cov pa roj. Nws raug nquahu kom koj siv tib cov roj rau cov khoom siv ntxiv yog tias xav tau, yog li muab kev tiv thaiv zoo tshaj plaws los ntawm cov roj uas koj tau xaiv
Dab tsi yog regenerated thiab hluavtaws fibers?
Cov fibers ntuj muaj xws li paj rwb, pluab, ntaub plaub, thiab lwm yam. Regenerated fibers yog cov ntaub ntawv ntuj uas tau ua tiav rau hauv cov qauv fiber ntau. Regenerated fibers xws li cellulose thiab ntoo pulp yog siv los ua cov ntaub ntawv xws li rayon thiab acetate. Synthetic fibers yog cov txiv neej ua los ntawm cov tshuaj
Dab tsi yog regenerated hluavtaws fibers?
Regenerated Fibers. Regenerated fiber yog tsim los ntawm dissolving lub cellulose cheeb tsam ntawm cov nroj tsuag fiber nyob rau hauv cov tshuaj thiab ua rau nws mus rau hauv fiber dua (los ntawm txoj kev viscose). Txij li thaum nws muaj cellulose zoo li paj rwb thiab hemp, nws tseem hu ua 'regenerated cellulose fiber.'
Yuav ua li cas yog cov roj ib txwm siv es tsis txhob ntawm hluavtaws?
Raws li cov roj ib txwm txav los ntawm lub tsheb lub cav, nws degrades maj mam yog li tawm hauv cov khoom tsis zoo thiab tseem ua rau muaj cov sludge. Nws tuaj yeem cuam tshuam kev ua haujlwm ntawm koj lub tsheb lub cav thiab lub neej ntawm lub tsheb. Cov roj hluavtaws tuaj nrog cov impurities tsawg thiab yog cov sludge-resistant ntau dua
