Hunhu hwenylon 6 POY ine simba guru pakuita kweDTY.Nekuti kune zvakawanda zvinofurira zvinhu, pesvedzero yePOY yemafuta emukati paDTY mhando iri nyore kufuratirwa.
Mukugadzirisa kweDTY, mafuta emukati efilament yakasvibirira anotarisisa kukweshana kuri pakati pefilament nesimbi uye kukweshana kuri pakati pefilament ne disc.Kana iyo filaments ichipfuura nepakati twister disc, iyo filaments ine friction yakasimba kune imwe neimwe munzira inochinjika.Filaments isingakwanise kutsungirira rudzi urwu rwekukwesha inoburitsa fibrils uye yakatyoka magumo.Muchiitiko ichi, mafuta emukati anofanirwa kugadziriswa kuti aderedze kusawirirana kwakasimba pakati pemafilaments.Nekudaro, kana static friction yakadzikira, zvinokonzeresa kutsvedza kwePOY uye kukonzera kumonyoroka kutiza kana uchigadzira DTY.Kuwedzera kutenderera kwemhepo kunogona kudzivirira kutsvedza, asi kukonzera kuwedzera kwemesh chiitiko.Kunze kwemhando yeDTY, POY yeoiri yemukati ine pesvedzero huru pakuchinjika uye nharaunda yekushanda mumashure ekugadzirisa.
Oiri yemukati meshinda yePOY ine hukama nekupfeka uye huwandu hwe "snowflakes" inogadzirwa panguva yenylonDTY kugadzirisa.Kana mafuta ePOY ari pasi, monomer content mu "snowflake" inowedzera, izvo zvinoratidza kuti dhigirii yekupfeka yefilament pane friction disc inowedzera.Kana mafuta ePOY aripamusoro, kuumbwa kweoiri mu "snowflake" kunowedzera, zvichiratidza kupera kushoma.Kuseta kwakaringana POY oiri huwandu kwakakosha zvakanyanya kune naironi POY uye DTY kugadzirwa.Nemhando imwe chete yemafuta anozora, kuumbwa kwe "snowflake" kunonyanya kukanganiswa nemafuta ari muPOY kana iyo linear filament density uye yakazara density yefiber isingachinji.
Kana iyo mafuta emukati ePOY ari 0.45% ~0.50%, DTY ine hurema hudiki hwekutaridzika, yakanakisa kugadzirisa kugadzikana, iyo yakareba hutsanana kutenderera, yakanyanya kubuda uye mhando yepamusoro.Izvi zvinodaro nekuti kana mafuta ari mukati akadzikira, simba rakabatana pakati pemafilaments ega harina kunaka, izvo zvinotungamira mukusiyana kwePOY, zvichikonzera kushushikana kwakanyanya kwekusunungura kwePOY uye kuwedzera kwekuputsika kana kugadzirisa DTY.Nekune rumwe rutivi, kana POY yemafuta ari pasi zvakanyanya, iyo dynamic friction coefficient pakati pefilament uye friction disc yakanyanya kukwira, zvichikonzera kukwesha kwakanyanya uye kuwedzera kweDTY fibrils.Nekudaro, kana mafuta arimo akanyanya kukwira, dhizaini yekukwenya kweiyo mumiriri wemafuta yakadzikira, zvichikonzera kusakwana kwekukweshana pakati pe friction disc uye filament.Muchiitiko ichi, filament inotsvedza pane friction disc mutwister, zvichikonzera intermittent stiff filament, kureva tight filament.Uyezve, nhamba huru ye "snowflakes" inobudiswa pa friction disc nekuda kwekukwirira kwepamusoro uye kupisa kwefilaments.Kana aya "snowflakes" akasabviswa nekufamba kwenguva, anosvibisa pamusoro peiyo friction disc, zvichikonzera kukurumidza kuchinjika kwemafilaments pakupinda nekusiya twister nekumonyorora kupukunyuka.Pachave zvakare nenhamba yakakura yekuremara senge tight filaments, izvo zvinokanganisa kuita kwedhayi kweDTY.
