Ama-polyester chips(i-polyethylene terephthalate) i-polymerized kusuka ku-terephthalic acid ecwengekile (PTA) ne-ethylene glycol.Ukubonakala kuyi-rice granular, futhi kunezinhlobonhlobo eziningi (konke ukukhanya, ukukhanya okuyingxenye, ukukhanya okukhulu, i-cationic, lokhu kuqedwa).
Emakethe ecashuniwe yama-chips e-polyester, uvame ukubona amagama athi "ukukhanya okukhulu", "ukuqothulwa okuncane" kanye "nokukhanya", okushiwo lapha ngokuqukethwe kwe-titanium dioxide (TiO2) kuma-polyester chips, engeza i-titanium dioxide (TiO2) ekuncibilikeni wukunciphisa ukucwebezela kwefiber."Ukukhanya okukhulu" (Yizheng chemical fiber ibizwa nangokuthi "ukukhanya okuphezulu") okuqukethwe kwe-titanium dioxide kuma-polyester chips kunguziro;Okuqukethwe kwe-titanium dioxide engxenyeni "ekhanyayo" ye-polyester cishe ku-0.1%;Okuqukethwe kwe-titanium dioxide ku-chip "semi-buthuntu" ye-polyester ngu (0.32±0.03)%;Okuqukethwe kwe-titanium dioxide ku-polyester chip "yokuqothulwa okugcwele" kungu-2.4% kuya ku-2.5%.
Ngokukhula okwandayo komnotho womhlaba kanye nokuthuthukiswa kwezinga lokuphila kwabantu, imboni yendwangu nezingubo ithuthuke ngokushesha.I-semi-dull polyester chip isetshenziselwe kabanzi ukudaya kwayo okuhle kakhulu, amandla aphezulu kanye nezakhiwo ezinhle kakhulu zokucubungula, futhi inkambu yokufakwa kwesicelo izonwetshwa usuku nosuku, futhi ibe izinto zokusetshenziswa eziyinhloko ze-textile fiber, ifilimu ye-polyester yezimboni, neminye imikhakha.
Ngokusho ukusetshenziswa ucezu ingahlukaniswa fibre grade polyester sika, ibhodlela grade polyester sika kanye ifilimu grade polyester sika izigaba ezintathu.
Ama-chips e-fiber grade polyester asetshenziselwa ukwenza i-polyester staple fiber kanye ne-polyester filament, okuyizinto zokusetshenziswa zokucubungula imicu kanye nemikhiqizo ehlobene yamabhizinisi e-polyester fiber.Ama-chips e-polyester ebangeni lebhodlela ahlukaniswe izigaba ezimbili ze-copolymerization kanye ne-homopolization, ezingahlukaniswa ngamabhodlela amanzi amaminerali, amabhodlela esiphuzo se-carbonated, ezinye iziqukathi zokudla nezinto zokupakisha ngokuya ngokusetshenziswa okuhlukile.Kusukela ekuqaleni kwefilimu ye-polyester ngawo-1950, ngenxa yezakhiwo zayo ezinhle kakhulu zemishini, ukumelana namakhemikhali kanye nokuzinza kwe-dimensional, njengoba ifilimu yokufaka ugesi kagesi iye yathuthukiswa ngokushesha futhi yasetshenziswa kabanzi.Ngokuthuthuka kwemboni yemishini yasendlini, ukusetshenziswa kwefilimu ye-polyester ewugqinsi kukhule ngokushesha.Eminyakeni yamuva nje, ifilimu ye-polyester ibilokhu isetshenziswa kakhulu ekupakisheni izinto, izinto zokuphrinta, izinto zokwakha, izinto zasehhovisi, izinto zikazibuthe nezinto zezithombe nezinye izici zomphakathi kanye nezinkambu ezisezingeni eliphezulu nezisezingeni eliphezulu.
Njengamanje, abakhiqizi abakhulu be-polyester bayisinyathelo esisodwa sokukhiqiza, i-PTA kanye ne-MEG polymerization ayisakhiqizi izingcezu, kodwa ishiya isixhumanisi esimaphakathi ngokuqondile ikhiqiza i-staple fiber kanye ne-filament.Ukushabalala kancane esiqeshini kubalelwa ku-60%, kodwa ukuphotha kocezu akunamakethe, akukho kuncintisana, futhi imakethe isobala.Ukukhiqizwa kwamanzi amaminerali kanye namanye amabhodlela esiphuzo ngezingcezu, ukukhiqizwa kwamanje kuye kwaba ngokweqile, ikhwalithi yabakhiqizi ayifani.Ithani elilodwa le-polyester lingenza amabhodlela angaphezu kuka-33,000.Ngaphezu kwalokho, ishidi eligaywe kabusha, okungukuthi, amabhodlela epulasitiki angcolile agaywa kabusha ukuze akhiqize i-fiber eyisisekelo, izindleko eziphansi, intengo ephansi, nokuhlanza imvelo.Kodwa ukushushumbisa kubi kakhulu, kukhathazwa ukuthi uma nje ikusasa selibaliwe lizophazamisa ukuhleleka kwemakethe.
