Kuyaziwa ukuba i-spandex fiber inokudaywa ngeedayi ezisasazekileyo kunye nedayi ye-asidi, kodwa ukukhawuleza kwezi dayi zimbini zimbi.Uninzi lovavanyo lubonakalise ukuba iidayi ezisebenzayo zenayiloni kunye nokusasaza idayi ye-cationic ngokusisiseko ayishiyi umbala kwi-spandex.Ngaba oku kubonisa ukuba ezi dayi zimbini azifanelekanga ukudaya i-spandex?Enyanisweni, akunjalo.Nge-catalysis yabancedisi abafanelekileyo, idayi esebenzayo ye-nylon ingasetyenziselwa ukudaya kwe-spandex, kwaye ukukhawuleza kunye nobunzulu bayo bungcono.Oku kulandelayo luhlalutyo oluneenkcukacha.
1. Kukho amalaphu ambalwa e-spandex acocekileyo kwiimarike, ngoko ukudaya kwe-spandex akuqhelekanga kuthi.Iilaphu ezicocekileyo ze-spandex zingasetyenziselwa kunye neempahla ezilula eziphantsi okanye iilaphu ze-inelastic, ezinokunyusa ukuqina kunye nokuqina kweempahla.Kwaye xa i-elastic fabric yoluliwe okanye icinezelwe, ukuba umbala we-spandex fiber awuhambisani ne-filament, kuya kuba nengxaki yokuvuza kombala we-spandex, efuna ukudaywa kwe-spandex.
2. Ukudaya kombala okhanyayo we-spandex, idayi ene-asidi okanye idayi ye-disperse ingasetyenziswa kwiimeko zokuhlambela ezine-asidi.Ngaphantsi kwemeko yokusebenzisa idosi yedayi efanayo, iidayi ezisasazwayo zinokukhawuleza okungcono kunedayi ezineasidi kwi-spandex, kodwa iidayi ezahlukeneyo ezisasazekileyo zinokukhawuleza okwahlukileyo kwi-spandex.Ngokubanzi, ukuba idosi yedayi ingaphantsi kwe-0.5%, ukusabalalisa idayi kungamkelwa.
3. ISpandexfiber yifayibha elastiki ephezulu.Ukuqwalasela ukuba ukudaya i-spandex ixesha elide phantsi kobushushu obuphezulu kuya kukhokelela kukusilela kweelastiki, ngokuqhelekileyo idayiwe ngaphantsi kwe-100℃.Ngaphezu koko, i-spandex ayixhathisi kwi-alkali, kwaye iidayi ezisasazwayo kunye nedayi ye-asidi zifanelekile ukudaya kwiimeko ezine-acidic.Ngokuqhelekileyo, ukudaya kwe-spandex kuqhutyelwa kwiimeko ze-acidic kunye ne-pH malunga ne-5.
4. Iindidi ezahlukeneyo zedayi, kunye nabancedisi abafanelekileyo njengama-mediums, zingasetyenziselwa ukudaya i-spandex fiber.Olu hlobo lwabancedisi kwimarike lubizwa ngokuba yi-spandex coloring agent okanye i-spandex colorant, esetyenziselwa ikakhulu ukufa kwedayi esebenzayo yenayiloni kunye nedayi yeasidi kwi-spandex, edla ngokuqhayisa ngeepropathi ze-amphoteric ion.Umgaqo wesenzo urhabaxa ngolu hlobo lulandelayo: Ngaphantsi kweemeko ze-acidic, i-amide bond kunye namanye amaqela kwi-spandex ionize, kunye nentlawulo efanelekileyo, enokuthi ibe nokusabela kunye nombala we-spandex.Emva koko i-ejenti yokulungisa igxininiswe kwi-spandex kuba umbala we-spandex uqukethe i-amino positive ions, idayi kunye nombala we-spandex nawo unokudibaniswa.
5. Imithetho ngokubanzi yokukhawuleza emva kokudaywa kwe-spandex: Hlamba > ibala lokubila (i-asidi) > ukumanzisa, kunye nokukhawuleza kwe-web rubbing kungcono kakhulu kunokomisa okomileyo.
