Kungani I-Dispersion Fastness Impofu?

Ukudaya okuhlakazayo kusebenzisa kakhulu izinga lokushisa eliphezulu kanye nokucindezela okuphezulu lapho kudaya imicu ye-polyester.Nakuba ama-molecule kadayi ohlakazekayo emancane, awanakuqinisekisa ukuthi wonke ama- molecule kadayi angena emculweni ngesikhathi sokudaywa.Abanye odayi abahlakazayo bazonamathela endaweni yefiber, okuholela ekusheshiseni okubi.Isetshenziselwa ukucekela phansi ama-molecule edayi angangenanga ku-fiber, ukuthuthukisa ukushesha, nokuthuthukisa umthunzi.

Hlaza udayi wezindwangu ze-polyester, ikakhulukazi ngemibala ephakathi nendawo emnyama, ukuze ususe ngokuphelele imibala entantayo nama-oligomer asele ebusweni bendwangu futhi uthuthukise ukushesha kokudaya, ngokuvamile kuyadingeka ukwenza ukuhlanza okuncishisiwe ngemuva kokudaya.

Indwangu ehlanganisiwe ngokuvamile ibhekisela entanjeni eyenziwe ngezingxenye ezimbili noma ngaphezulu ezihlanganisiwe, ngakho le ndwangu inezinzuzo zalezi zingxenye ezimbili.Futhi ngokulungisa isilinganiso sengxenye, izici eziningi zesinye sezingxenye zingatholakala.

Ukuxuba ngokuvamile kubhekisela ekuhlanganiseni kwefayibha eyisisekelo, okungukuthi, imicu emibili yezingxenye ezihlukene ixutshwa ndawonye ngendlela yemicu eyisisekelo.Isibonelo: Indwangu ehlanganisiwe ye-polyester-cotton, evame ukubizwa nangokuthi i-T/C, CVC.T/R, njll. Ilukwe ngenhlanganisela ye-polyester staple fiber kanye ne-cotton fiber noma i-fiber eyenziwe ngumuntu.Izinzuzo zayo yilezi: inokubukeka nokuzwakala kwendwangu kakotini yonke, yenza buthaka i-chemical fibre luster kanye ne-chemical fiber ukuzwa kwendwangu ye-polyester, futhi ithuthukisa izinga.

Ukushesha kombala okuthuthukisiwe, ngoba indwangu ye-polyester inombala ekushiseni okuphezulu, ukushesha kombala kuphakeme kunokotini, ngakho-ke ukushesha kombala wendwangu ehlanganisiwe ye-polyester-ukotini nakho kuyathuthukiswa uma kuqhathaniswa nokotini.

Kodwa-ke, ukuze kuthuthukiswe ukushesha kombala kwezindwangu ze-polyester-cotton, ukuhlanzwa kokunciphisa (okubizwa ngokuthi i-R / C) kufanele kwenziwe, futhi ngemva kokwelashwa ngemva kokudaya okuphezulu nokusabalalisa.Ukushesha kombala okulungile kungatholakala kuphela ngemva kokunciphisa nokuhlanza.

Ukuhlanganiswa kwe-fiber okuyisisekelo kuvumela izici zengxenye ngayinye ukuthi ziboniswe ngokulinganayo.Ngokufanayo, okunye ukuxuba kwengxenye nakho kungadlala izinzuzo zako ukuze kuhlangatshezwane nezidingo ezithile zokusebenza noma ukunethezeka noma zezomnotho.Kodwa-ke, izindwangu ezihlanganisiwe ze-polyester-cotton ziyahlakazwa futhi zidaywe emazingeni okushisa aphezulu.Okuphakathi, ngenxa yokuxuba ukotini noma i-rayon fiber, futhi izinga lokushisa lokudaya alikwazi ukuba ngaphezu kwezinga lokushisa lendwangu ye-polyester.Kodwa-ke, izindwangu ze-polyester-cotton noma i-polyester-cotton rayon, ngaphansi kokugqugquzelwa kwe-alkali eqinile noma i-sodium hydroxide, izobangela amandla e-fiber noma amandla okudabula ukuba ehle kakhulu, futhi kunzima ukufeza ikhwalithi yomkhiqizo kuzixhumanisi ezilandelayo.

Inqubo yokufuduka okushisayo kodayi abahlakazayo ingachazwa kanje:

1. Enqubweni yokudaya izinga lokushisa eliphezulu, ukwakheka kwe-polyester fiber kuyaxega, udayi ohlakaziwe uyahlakazeka usuka ebusweni bomucu ungene ngaphakathi kwefiber, futhi usebenza ikakhulukazi ku-polyester fiber nge-hydrogen bond, i-dipole attraction kanye ne-van der. Waals force.

2. Uma i-fiber edayiwe ingaphansi kokwelashwa kokushisa okuphezulu, amandla ashisayo anika amandla okusebenza aphezulu eketangeni le-polyester elide, eliqinisa ukudlidliza kweketango lamangqamuzana, futhi i-microstructure yefayibha iyakhululeka futhi, okuholela ekuxhumaneni phakathi amanye amangqamuzana odayi kanye neketango elide le-polyester Kuba buthakathaka.Ngakho-ke, amanye ama-molecule kadayi anamandla omsebenzi aphezulu kanye nezinga eliphakeme lokuzimela afuduka esuka ngaphakathi kwefayibha aye ongqimbeni olungaphezulu lwefayibha enesakhiwo esixegayo, ahlanganiswe nendawo yefayibha ukuze akhe udayi ongaphezulu.

3. Ngesikhathi sokuhlolwa kokushesha okumanzi.Amadayi angaphezulu angaboshiwe ngokuqinile, namadayi anamathela engxenyeni enamathelayo kakotini, azoshiya kalula i-fiber ukuze afake isisombululo futhi angcolise indwangu emhlophe;noma unamathele ngqo endwangu emhlophe yokuhlola ngokuhlikihla, ngaleyo ndlela ubonise ukushesha okumanzi nokungqubuzana komkhiqizo odayiwe ukushesha kuncipha.
