Kuyaziwa ukuthi i-spandex fiber ingadaywa ngodayi abahlakazekile kanye nodayi be-asidi, kodwa ukushesha kwalaba odayi ababili kubi.Iningi lokuhlola lifakazele ukuthi odayi abasebenzayo benayiloni kanye nodayi be-cationic abasakazi ngokuyisisekelo abawushiyi umbala ku-spandex.Ingabe lokhu kubonisa ukuthi odayi ababili abafanele ukudaya i-spandex?Eqinisweni, akunjalo.Nge-catalysis yabasizi abafanelekile, odayi abasebenzayo benayiloni bangasetshenziselwa ukudaya i-spandex, futhi ukushesha nokujula kwayo kungcono.Okulandelayo ukuhlaziya okuningiliziwe.
1. Kunezindwangu ezimbalwa ze-spandex ezihlanzekile emakethe, ngakho-ke ukudaya kwe-spandex akuvamile kithi.Izindwangu ezihlanzekile ze-spandex zingasetshenziswa ngokuhambisana nezindwangu eziphansi ezinwebekayo noma izindwangu ze-inelastic, ezingandisa ukuqina nokuqina kwezindwangu.Futhi lapho indwangu ye-elastic yeluliwe noma icindezelwe, uma umbala we-spandex fiber ungahambisani ne-filament, kuyoba nenkinga yokuvuza kombala we-spandex, okudinga ukudaya kwe-spandex.
2. Ukuze uthole ukudaya kombala okhanyayo we-spandex, udayi we-acidic noma udayi we-disperse ungasetshenziswa ezimweni zokugeza ezine-acidic.Ngaphansi kwesimo sokusebenzisa umthamo ofanayo kadayi, odayi abahlakazayo banokushesha okungcono kunodayi abane-asidi ku-spandex, kodwa odayi abahlukene abahlakazayo banokushesha okuhlukile ku-spandex.Ngokuvamile, uma umthamo wedayi ungaphansi kuka-0.5%, amadayi ahlakaziwe angamukelwa.
3. I-Spandexfiber iphezulu i-elastic fiber.Uma kucatshangelwa ukuthi ukudaya i-spandex isikhathi eside ngaphansi kwezinga lokushisa eliphezulu kuzoholela ekuhlulekeni kokunwebeka, kuvame ukudaywa ngaphansi kuka-100℃.Ngaphezu kwalokho, i-spandex ayimelani ne-alkali, futhi odayi abahlakazayo kanye nodayi be-asidi bafanele ukudaywa ezimeni ezine-asidi.Ngokuvamile, ukudaya kwe-spandex kwenziwa ezimeni ezine-asidi ezine-pH engaba ngu-5.
4. Izinhlobonhlobo zamadayi, anezinsiza ezifanele njengama-mediums, zingasetshenziswa ukudaya i-spandex fiber.Lolu hlobo lwabasizi emakethe lubizwa ngokuthi i-spandex coloring agent noma i-spandex colorant, esetshenziselwa kakhulu ukufa kodayi abasebenzayo benayiloni nodayi be-asidi ku-spandex, evame ukuziqhayisa ngezakhiwo ze-amphoteric ion.Isimiso sesenzo simaholoholo kanjena: Ngaphansi kwezimo ezine-asidi, ibhondi ye-amide namanye amaqembu ku-spandex ionize, enenkokhiso eqondile, engase ibe nokusabela ngombala we-spandex.Khona-ke i-ejenti yokulungisa ilungiswa ku-spandex ngoba umbala we-spandex uqukethe ama-ion amino positive, udayi kanye nombala we-spandex nakho kungahlanganiswa.
5. Imithetho evamile yokushesha ngemva kokudaywa kwe-spandex: Geza > ibala lomjuluko (i-asidi) > ukucwiliswa emanzini, futhi ukushesha kokuhlikihla kwewebhu kungcono kakhulu kunokokuhlikihla okomile.
