Izinga lenayiloni 6 POY linomthelela omkhulu ekucutshungulweni kwe-DTY.Ngoba kunezici eziningi ezinomthelela, umthelela wokuqukethwe kukawoyela we-POY kukhwalithi ye-DTY kulula ukuzitshwa.
Ekucutshungulweni kwe-DTY, okuqukethwe kukawoyela we-filament eluhlaza kunquma ukungqubuzana okuguquguqukayo phakathi kwe-filament nensimbi kanye nokungqubuzana okuguquguqukayo phakathi kwe-filament ne-disc.Lapho ama-filaments edlula ku-twister disc, imicu inokungqubuzana okuqinile komunye nomunye ohlangothini oluphambene.Izintambo ezingakwazi ukubekezelela lolu hlobo lokungqubuzana zizokhiqiza ama-fibril neziphetho eziphukile.Kulesi simo, okuqukethwe kwamafutha kufanele kulungiswe ukuze kuncishiswe ukungqubuzana okumile phakathi kwama-filaments.Nokho, uma ukungqubuzana okumile kuphansi kakhulu, kuzobangela ukushelela kwe-POY futhi kubangele ukuphunyuka kwe-twist lapho kucutshungulwa i-DTY.Ukwandisa ukushuba kwesimo somoya kungavimbela ukushelela, kodwa kubangele ukwanda kwesenzakalo semeshi.Ngaphandle kwekhwalithi ye-DTY, okuqukethwe kukawoyela we-POY kunethonya elikhulu ekuzivumelaniseni nezimo kanye nendawo yokusebenza kunqubo yangemuva kokucubungula.
Okuqukethwe kukawoyela kwentambo ye-POY kuhlobene nokuguga kanye nenani "lamakhekheba eqhwa" akhiqizwa ngesikhathi sokucutshungulwa kwe-nylonDTY.Uma okuqukethwe kukawoyela kwe-POY kuphansi, okuqukethwe kwe-monomer ku-"snowflake" kuyanda, okubonisa ukuthi izinga lokuguga le-filament ku-friction disc liyakhuphuka.Uma okuqukethwe kukawoyela we-POY kuphezulu, ukwakheka kukawoyela ku-"snowflake" kuyanda, okubonisa ukuguga okuncane.Ukusetha inani elifanele lokugcoba i-POY kubaluleke kakhulu ekukhiqizeni inayiloni POY kanye ne-DTY.Ngohlobo olufanayo lwe-ejenti yokugcoba, ukwakheka kwe-"snowflake" kuthinteka kakhulu okuqukethwe kwamafutha e-POY lapho ukuminyana kwe-filament eqondile kanye nokuminyana okuphelele kwe-fiber kungaguquki.
Uma okuqukethwe kukawoyela kwe-POY kungu-0.45%～0.50%, i-DTY inokukhubazeka okuncane kokubukeka, ukuzinza okungcono kakhulu kokucubungula, umjikelezo omude wokuhlanzeka, okukhiphayo okuphezulu kakhulu kanye nekhwalithi engcono kakhulu.Lokhu kungenxa yokuthi uma okuqukethwe kukawoyela kuphansi kakhulu, amandla okubumbana phakathi kwemicu ngayinye ampofu, okuholela ekwehlukaneni kwe-POY, okubangela ukungezwani okukhulu kwe-POY nokwenyuka kwezinga lokuphuka lapho kusetshenzwa i-DTY.Ngakolunye uhlangothi, lapho okuqukethwe kukawoyela we-POY kuphansi kakhulu, i-coefficient yokungqubuzana okuguquguqukayo phakathi kwe-filament ne-friction disc iphezulu kakhulu, okubangela ukungqubuzana okukhulu nokwanda kwama-DTY fibrils.Kodwa-ke, uma okuqukethwe kukawoyela kuphezulu kakhulu, i-coefficient ye-dynamic friction ye-ejenti kawoyela iphansi kakhulu, okubangela ukungqubuzana okunganele phakathi kwe-friction disc kanye ne-filament.Kulesi simo, i-filament izoshelela ku-friction disc ku-twister, ibangele i-filament eqinile ephakathi, okungukuthi i-tight filament.Ngaphezu kwalokho, inani elikhulu lama-"snowflakes" akhiqizwa kwi-disc friction ngenxa yokungqubuzana okuphezulu nokushisa kwama-filaments.Uma lawa "amakhekheba eqhwa" engasuswa ngesikhathi, azongcolisa idiski le-friction, okuholela ekuguquguqukeni kwesivinini semicu lapho ingena futhi ishiya ukuphunyuka kwe-twister nokusonta.Kuzophinde kube nenani elikhulu lamaphutha njengama-tight filaments, okuzophazamisa ukusebenza kokudaya kwe-DTY.
