Umgangatho wenayiloni 6 POY unempembelelo enkulu ekusebenzeni kweDTY.Ngenxa yokuba zininzi izinto ezinempembelelo, impembelelo ye-oyile ye-POY kumgangatho we-DTY kulula ukungahoywa.
Kwinkqubo ye-DTY, umxholo we-oyile we-filament eluhlaza umisela ukungqubuzana okuguquguqukayo phakathi kwe-filament kunye nesinyithi kunye nokuxhatshazwa okuguquguqukayo phakathi kwe-filament kunye ne-disc.Xa i-filaments idlula kwi-disc twister, i-filaments ine-friction enamandla kunye nomnye kwicala elinqamlezayo.Iifilaments ezingakwaziyo ukunyamezela olu hlobo lwengxabano ziya kuvelisa iifibrils kunye neziphelo eziphukileyo.Kule meko, umxholo weoli kufuneka ulungelelaniswe ukuze unciphise ukungqubuzana kwe-static phakathi kwee-filaments.Nangona kunjalo, ukuba i-static friction iphantsi kakhulu, iya kubangela ukutyibilika kwe-POY kwaye ibangele ukubaleka kwe-twist xa kusetyenzwa i-DTY.Ukonyusa uxinezeleko olujikelezayo kunokuthintela ukutyibilika, kodwa kubangele ukwanda kwesenzeko semesh.Ngaphandle komgangatho we-DTY, umxholo we-oyile ye-POY unempembelelo enkulu ekuguquguqukeni kunye nemeko yokusebenza kwinkqubo yasemva kokulungiswa.
Umxholo weoli ye-POY yarn ihambelana nokunxiba kunye nobungakanani be "snowflakes" eziveliswe ngexesha lokucutshungulwa kwe-nylonDTY.Xa umxholo we-oyile we-POY uphantsi, umxholo we-monomer kwi "snowflake" uyanda, okubonisa ukuba idigri yokunxiba ye-filament kwi-friction disc iyanda.Xa umxholo we-oyile ye-POY uphezulu, ukubunjwa kweoli kwi "snowflake" kuyanda, kubonisa ukuguga okuncinci.Ukuseta isixa se-oyile esifanelekileyo se-POY kubaluleke kakhulu kwi-POY yenylon kunye nemveliso ye-DTY.Ngohlobo olufanayo lwe-oiling agent, ukubunjwa kwe "snowflake" kuchaphazeleka kakhulu ngumxholo we-oyile ye-POY xa ukuxinana kwe-filament yomgca kunye nokuxinana okupheleleyo kwefiber kungatshintshi.
Xa umxholo we-oyile ye-POY yi-0.45% ~0.50%, i-DTY ineziphene ezincinci zokubonakala, ukuzinza okungcono kakhulu, umjikelezo omde wococeko, imveliso ephezulu kunye nomgangatho ophezulu.Oku kungenxa yokuba xa umxholo we-oyile uphantsi kakhulu, amandla okubambisana phakathi kwee-filaments ngabanye ahluphekile, nto leyo ekhokelela ekuhlukeni kwe-POY, ebangela ukuxinzezeleka okugqithisileyo kwe-POY kunye nokunyuka kwezinga lokuqhawula xa kusetyenzwa i-DTY.Ngakolunye uhlangothi, xa umxholo we-oyile ye-POY uphantsi kakhulu, i-coefficient ye-friction eguquguqukayo phakathi kwe-filament kunye ne-disc ye-friction iphezulu kakhulu, ibangela ukuxhatshazwa okugqithisileyo kunye nokunyuka kwe-DTY fibrils.Nangona kunjalo, xa umxholo weoli uphezulu kakhulu, i-coefficient ye-friction ye-oyile iphantsi kakhulu, ibangela ukungqubuzana okwaneleyo phakathi kwe-friction disc kunye ne-filament.Kule meko, i-filament iya kutyibilika kwi-disc ye-friction kwi-twister, ibangele i-intermittent stiff filament, ebizwa ngokuba yi-tight filament.Ngaphezu koko, inani elikhulu le "snowflakes" ziveliswa kwi-disc ye-friction ngenxa ye-friction ephezulu kunye nokushisa kwee-filaments.Ukuba ezi "snowflakes" azisuswanga ngexesha, ziya kungcolisa umphezulu wediski ye-friction, ekhokelela ekutshintsheni kwesantya se-filaments xa ingena kwaye ishiya i-twister kunye ne-twist yokubalekela.Kuya kubakho nenani elikhulu leziphene ezifana ne-tight filaments, eziya kuchaphazela ukusebenza kokudaya kwe-DTY.
