Melt spinning yog txheej txheem tseem ceeb hauv kev tsim cov polyester fibers. Los ntawm cov txheej txheem no, polyester polymers tau ua tiav rau hauv nplua, elongated fibers dav siv hauv textiles thiab cov khoom lag luam.
Ntawm no yog cov ncauj lus kom ntxaws cov kauj ruam thiab kev paub txog ntawm polyester melt spinning:
Cov txheej txheem txheej txheem:
Melting: Cov polyester polymer yog thawj melted ntawm qhov kub thiab txias los tsim cov kua dej tsis sib xws. Qhov no feem ntau tshwm sim ntawm qhov kub thiab txias ib puag ncig 280-290 degree .
Extrusion: Lub molten polyester yog extruded los ntawm ib tug yaj extruder thiab yuam los ntawm ib tug spinneret nrog zoo qhov. Txoj kab uas hla thiab cov duab ntawm lub qhov spinneret txiav txim siab qhov kawg fiber ntau lub thickness thiab cross-sectional duab.
Cooling thiab Solidification: Cov extruded molten fibers yog sai txias thiab solidified los ntawm kev dhau los ntawm ib tug txias nruab nrab (feem ntau yog cua los yog dej txias), tsim cov khoom fibers.
Kev kos duab: Lub solidified fibers tau dhau los ua cov txheej txheem kos duab los txhim kho lawv lub zog thiab elongation. Cov txheej txheem kev kos duab feem ntau tshwm sim nyob rau hauv cov cua sov, tso cai rau cov saw hlau molecular ntawm cov fibers ua kom zoo dua qub, yog li txhim kho cov khoom siv ntawm cov fibers.
Kev kho mob tom qab: Cov fibers kos tau dhau los ua cov txheej txheem tom qab kev kho mob, xws li kev teeb tsa kub, roj, thiab winding, txhawm rau txhim kho kev ruaj ntseg thiab spinnability ntawm cov fibers.
Technical nta:
Fiber ntau: Cov txheej txheem melting spinning endows polyester fibers nrog zoo heev zog, abrasion tsis kam, thiab elasticity. Cov fibers muaj ib tug du nto thiab zoo txhais tes.
Kev Ua Tau Zoo: Cov txheej txheem yaj spinning yog qhov ua tau zoo thiab tsim nyog rau kev lag luam loj.
Ntau yam: Los ntawm kev kho qhov tsim ntawm spinneret thiab spinning tsis, polyester fibers ntawm txawv thicknesses thiab cross-sectional duab tuaj yeem ua tau raws li ntau yam kev xav tau.
Qhov chaw thov:
Textiles: Polyester fibers yog dav siv los ua ntau yam khaub ncaws fabrics, tsev textiles (xws li ntaub pua txaj, ntaub pua plag), thiab ntaub pua plag.
Muaj ntaub: Siv los ua cov ntaub lim dej, cov khoom siv conveyor, lub rooj zaum siv, thiab lwm yam khoom lag luam.
Non-woven Fabrics: Siv los tsim cov ntaub ntawv kho mob tsis-woven, pov tseg cov khoom tiv thaiv, thiab lwm yam.
Kev sib tw thiab kev tsim kho tshiab:
Environmental Impact: Cov txheej txheem melting spinning yuav tsum tau kub siab, siv lub zog tseem ceeb thaum cua sov thiab txias. Cov kws tshawb fawb tab tom tsim cov txheej txheem tsim hluav taws xob ntau dua.
Muaj nuj nqi Fibers: Txhawm rau ua kom tau raws li cov hom phiaj tshwj xeeb, cov txheej txheem melting spinning yog txuas ntxiv tsim kho tshiab, tsim tshwj xeeb polyester fibers nrog antibacterial, nplaim-retardant, UV-resistant, thiab lwm yam dej num.
