Iintsinga ezisisiseko zinokwahlulwa ngokweendidi ezahlukeneyo ngokwemigangatho yokuhlela. Ngokwemathiriyeli ekrwada inokwahlulwa ibe yifiber esisiseko esisiseko kunye nefayibha ehlaziyiweyo. I-fiber esisiseko yeprayimari yenziwe kwi-PTA kunye ne-ethylene glycol nge-polymerization, ukujikeleza kunye nokusika, eyaziwa ngokuba yi "Fiber yekhemikhali enkulu", emva kokumisa, ukunyibilika, ukujikeleza, ukusika kwenziwa, eyaziwa ngokuba yi "Fiber encinci yekhemikhali." Iintsinga eziphambili zohlulwe zibe yinyibilika ngokuthe ngqo kunye nebhetshi ejikelezayo ngokweenkqubo ezahlukeneyo zokusonta. I-Melt ngqo i-fiber staple ejikelezayo iveliswa kwi-PTA kunye ne-ethylene glycol ngokujikeleza ngokuthe ngqo ngaphandle kokuvelisa i-polyester chips. Okwangoku, itekhnoloji yokunyibilika ngokuthe ngqo yamkelwe kwimveliso yeentlobo zefiber eziqhelekileyo eTshayina. I-Batch spinning, ekwabizwa ngokuba yi-chip spinning, yinkqubo yokuvelisa iintsinga ezivela kwi-PET chips. Xa kuthelekiswa nenkqubo yokusonta ngokuthe ngqo, i-batch spinning inciphisa iyunithi yepolyester, inyusa ukomiswa kwe-chip kunye neyunithi yokunyibilika, kwaye le nkqubo ilandelayo iyafana. Iintsinga ezisisiseko zohlulwe kakhulu zibe ziindidi ezintathu ngokosetyenziso lwazo olwahlukileyo: ukusonta, ukugcwaliswa kunye nokungalukwanga. Ukuphotha kolona setyenziso lubalulekileyo lweentsinga ezisisiseko, kuquka umqhaphu kunye noboya obusonta imiba emibini. Umqhaphu kunye noboya obusontayo bubhekisa kumqhaphu kunye noboya obusontayo boboya, ngokulandelelanayo. Ubungakanani bomqhaphu ojikelezayo mkhulu, kubandakanywa i-polyester ecocekileyo yokusonta, i-polyester-cotton edibeneyo, i-polyester-viscose edibeneyo kunye ne-polyester staple fibre yokuthunga intambo yokuthunga. Ukusonta uboya ikakhulu kubandakanya ipolyester-nitrile, umxube woboya wepolyester kunye nokuveliswa kweengubo.

Ukuzalisa ubukhulu becala yifayibha emfutshane ngendlela yokuzalisa, njengezihluzi zendlu kunye nempahla yokugquma impahla, njengebhedi, impahla yomqhaphu, ifenitshala yesofa, izinto zokudlala ezimfumamfuma, ezinjengokuzaliswa. Uninzi lwezi ntsinga ziyi-polyester staple fibers. I-nonwovens lulwandiso losetyenziso lwefiber ezisisiseko kwaye ziphuhliswe ngokukhawuleza kwiminyaka yakutshanje. Iindwangu ezingalukwanga zisetyenziswa ngokubanzi, njengeempahla eziphothiweyo ezingalukiweyo ezisetyenziswa ikakhulu kwimicibisholo emanzi, iindawo zonyango, i-geotextiles, ilaphu lesiseko lesikhumba, i-linoleum Kieb, njl. Okwangoku, elona candelo likhulu lentengiso yeemveliso eziphambili zepolyester ezijikelezayo.
