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.
