Imicu eyisisekelo ingahlukaniswa ngezigaba ezihlukene ngokuya ngamazinga okuhlukanisa ahlukene. Ngokusho kwezinto zokusetshenziswa zingahlukaniswa zibe i-fiber staple staple kanye ne-staple fiber evuselelwe kabusha. I-fiber eyisisekelo eyisisekelo yenziwa nge-PTA kanye ne-ethylene glycol ngokwenza i-polymerization, ukuphotha nokusika, okuvame ukubizwa ngokuthi "I-Fiber yamakhemikhali Enkulu", ngemva kokumiswa, ukuncibilika, ukuphotha, ukusika kwenziwa, okuvame ukwaziwa ngokuthi "I-Fiber yamakhemikhali amancane." Imicu eyisisekelo eyisisekelo ihlukaniswe yaba ukuphotha okuqondile okuncibilikayo kanye ne-batch spinning ngokwezinqubo ezihlukene zokuphotha. I-Melt direct spinning staple fiber ikhiqizwa nge-PTA kanye ne-ethylene glycol ngokuphotha okuqondile ngaphandle kokukhiqiza ama-polyester chips. Njengamanje, ubuchwepheshe bokuphotha be-ncibilika busetshenziswa ngokuyisisekelo ekukhiqizeni izinhlobo ezijwayelekile ze-staple fiber e-China. I-batch spinning, eyaziwa nangokuthi i-chip spinning, inqubo yokukhiqiza imicu kusuka kuma-PET chips. Uma kuqhathaniswa nenqubo yokuphotha eqondile, i-batch spinning kunciphisa iyunithi ye-polyester, kwandisa ukomiswa kwe-chip kanye neyunithi yokuncibilika, futhi inqubo elandelayo iyafana ngokuyisisekelo. Imicu eyisisekelo ihlukaniswa kakhulu izigaba ezintathu ngokuya ngokusetshenziswa kwayo okuhlukene: ukuphotha kwentambo, ukugcwaliswa kanye nokungaluki. Ukuphotha kuwukusetshenziswa okubaluleke kakhulu kwemicu eyisisekelo, okuhlanganisa ukotini noboya obuphotha izici ezimbili. Ukuphotha kukakotini novolo kubhekisela kukotini nefayibha yoboya, ngokulandelana. Inani lokuphotha kukakotini likhulu, kuhlanganise ne-polyester pure spinning, i-polyester-cotton blended, i-polyester-viscose ehlanganisiwe kanye nokukhiqizwa kwentambo yokuthunga ye-polyester staple fiber. Ukuphotha uvolo ikakhulukazi kubandakanya i-polyester-nitrile, ingxube ye-polyester-wool kanye nokukhiqizwa kwezingubo zokulala.

Ukuphotha uvolo ikakhulukazi kuhlanganisa i-polyester-nitrile, i-polyester-wool blend kanye nokukhiqizwa kwezingubo zokulala. Ukugcwalisa ikakhulukazi i-fiber emfishane ngendlela yokugcwalisa, njengezigcwalisi zasendlini kanye nezinto zokufaka izingubo zokugqoka, njengezingubo zokulala, izingubo zikakotini, ifenisha kasofa, amathoyizi kanokusho, njengokugcwalisa. Iningi lalawa ma-staple fibers ama-polyester staple fibers angenalutho. Ama-Nonwovens ayisandiso se-staple fiber application futhi athuthuke ngokushesha eminyakeni yamuva. Izindwangu ezingezona ezilukiwe zisetshenziswa kakhulu, njengezindwangu ezingezona eziphothiweyo ezisetshenziswa kakhulu ekusuleni okumanzi, izinkundla zezokwelapha, i-geotextiles, indwangu yesisekelo sesikhumba, i-linoleum Kieb, njll. Njengamanje, ingxenye enkulu yemakethe yemikhiqizo ye-fiber staple polyester eyisisekelo.
