I-Dacron iwuhlobo olubalulekile lwefayibha yokwenziwa futhi igama lezentengiselwano le-polyester fiber e-China.Isekelwe ku-terephthalic acid (PTA) ecwengekile noma i-dimethyl terephthalic acid (DMT) kanye ne-ethylene glycol (MEG) njengezinto zokusetshenziswa, ngokusebenzisa i-esterification noma i-transesterification kanye ne-polycondensation reaction kanye nokulungiswa kwe-polymer - i-polyethylene terephthalate (PET), ukuphotha kanye ne-post- ukucubungula okwenziwe nge-fiber.Okubizwa ngokuthi i-polyester filament ubude obungaphezu kwamakhilomitha kasilika, umcu owenziwe ibhola.Ngokwezindlela ezahlukene zokukhiqiza, i-polyester filament ngokuvamile ihlukaniswe ngezigaba ezintathu: i-filament eyinhloko, i-stretch filament kanye ne-deformation filament.
Izici ze-polyester filament
Amandla: Imicu ye-polyester iqine ngokuphindwe kabili kunokotini futhi iqine ngokuphindwe kathathu kunovolo, ngakho izindwangu ze-polyester ziqinile futhi zihlala isikhathi eside.
Ukumelana nokushisa: ingasetshenziswa ku--70 ℃ ~ 170 ℃, iyindlela engcono kakhulu yokumelana nokushisa nokuzinza kokushisa kwamafayibha okwenziwa.
I-Elasticity: Ukunwebeka kwe-polyester kuseduze noboya, futhi ukumelana ne-crease kungcono kuneminye imicu.Indwangu ayinamibimbi futhi inokugcinwa komumo omuhle.
Ukumelana nokugqoka: Ukumelana nokugqokwa kwe-polyester kungokwesibili kunenayiloni, endaweni yesibili ku-fiber yokwenziwa.
Ukumuncwa kwamanzi: I-polyester inezinga eliphansi lokumunca amanzi kanye nezinga lokubuyisela umswakama kanye nokusebenza kahle kokufakwa kwamanzi.Kodwa-ke, ngenxa yokumuncwa kwamanzi aphansi kanye nogesi omile ophezulu okhiqizwa ukungqubuzana, ukusebenza kwemvelo kokukhangiswa kukadayi kubi.Ngakho-ke, i-polyester ngokuvamile idayiwe izinga lokushisa eliphezulu kanye nokudaya ngomfutho ophezulu.
Ukudaya: I-polyester ngokwayo ayinawo amaqembu e-hydrophilic noma izingxenye zokwamukela udayi, ngakho-ke ukudaya kwe-polyester kumpofu, kungadaywa ngodayi abahlakazayo noma odayi abangewona ama-ionic, kodwa izimo zokudaya zinzima.
Ukusetshenziswa kwe-polyester filament
I-polyester njenge-fiber yengubo, indwangu yayo ngemva kokugeza ukuze kuzuzwe umphumela wokungewona - ukushwabana, okungewona - ironing.I-polyester ivame ukuhlanganiswa noma ihlanganiswe nemicu ehlukahlukene, njenge-polyester kakotini, i-polyester yoboya, njll, esetshenziswa kabanzi ezintweni ezihlukahlukene zokugqoka kanye nezinto zokuhlobisa.I-polyester ingasetshenziswa embonini ngebhande lokuthutha, itende, i-canvas, ikhebula, inetha lokudoba, njll., ikakhulukazi intambo ye-polyester yamasondo, eseduze ne-nylon ekusebenzeni.I-polyester ingasetshenziswa futhi ezintweni zokufaka ugesi kagesi, indwangu yokuhlunga engamelana ne-asidi, indwangu yemboni yezemithi, njll. I-synthetic fiber isetshenziswe kabanzi emikhakheni ehlukahlukene yomnotho wezwe ngenxa yamandla ayo aphezulu, ukumelana nemihuzuko, ukumelana ne-asidi, ukumelana ne-alkali, okuphezulu. ukumelana nezinga lokushisa, isisindo esincane, ukufudumala, ukufakwa kahle kukagesi kanye nokumelana nesikhutha.
