Kutheni i-Dispersion Fastness ihlwempuzekile?

Ukusasaza ukudaya ikakhulu kusetyenziswa ubushushu obuphezulu kunye noxinzelelo oluphezulu xa kudayiwa imicu yepolyester.Nangona iimolekyuli zedayi ezisasazekileyo zincinci, azinakuqinisekisa ukuba zonke iimolekyuli zedayi zingena kwifayibha ngexesha lokudaya.Ezinye iidayi ezisasazwayo ziya kubambelela kumphezulu wefiber, okukhokelela ekukhawulezeni okubi.Isetyenziselwa ukutshabalalisa iimolekyuli zedayi ezingangenanga kwifiber, ukuphucula ukukhawuleza, kunye nokuphucula umthunzi.

Ukusasaza ukudaya kwedayi yamalaphu e-polyester, ngakumbi kwimibala ephakathi kunye nemnyama, ukuze kususwe ngokupheleleyo imibala edadayo kunye ne-oligomers eseleyo kumphezulu welaphu kunye nokuphucula ukukhawuleza kokudaya, ngokuqhelekileyo kuyimfuneko ukwenza ukucocwa kokunciphisa emva kokudaya.

Ilaphu elidityanisiweyo libhekisa kumsonto owenziwe ngamacandelo amabini okanye ngaphezulu adityanisiweyo, ngoko ke eli laphu lineengenelo kula malungu mabini.Kwaye ngokulungelelanisa umlinganiselo wecandelo, iimpawu ezininzi zesinye samacandelo zinokufumaneka.

Ukudibanisa ngokuqhelekileyo kubhekiselele kumxube wefayibha ezisisiseko, oko kukuthi, iintsinga ezimbini zamacandelo ahlukeneyo zixutywa kunye ngohlobo lweentsinga ezisisiseko.Umzekelo: ilaphu elidityanisiweyo le-polyester-cotton, ekwabizwa ngokuba yi-T / C, i-CVC.T/R, njl njl. Ilukwe ngomxube we-polyester staple fiber kunye ne-cotton fiber okanye i-fiber eyenziwe ngumntu.Izibonelelo zayo zezi: inenkangeleko kunye nokuziva kwelaphu le-cotton yonke, yenza buthathaka imichiza yefiber luster kunye nekhemikhali yefiber ivakale ngelaphu lepolyester, kwaye iphucula inqanaba.

Ukuphuculwa kokukhawuleza kombala, ngenxa yokuba ilaphu lepolyester linombala kubushushu obuphezulu, ukushesha kombala kuphezulu kunomqhaphu, ngoko ke ukushesha kombala welaphu elidityanisiweyo le-polyester-cotton nalo liyaphuculwa xa lithelekiswa nomqhaphu.

Nangona kunjalo, ukuphucula ukukhawuleza kombala weempahla ze-polyester-cotton, ukucocwa kokunciphisa (okubizwa ngokuba yi-R / C) kufuneka kwenziwe, kwaye emva kokunyanga emva kokudaya okuphezulu kunye nokusabalalisa.Ukukhawuleza kombala ofanelekileyo kunokufumaneka kuphela emva kokunciphisa kunye nokucoca.

Ukudibanisa i-fiber esisiseko kuvumela iimpawu zecandelo ngalinye ukuba ziboniswe ngokulinganayo.Ngokufanayo, okunye ukuxubana kwecandelo kunokudlala iinzuzo zabo ukuhlangabezana nokusebenza okanye ukuthuthuzela okanye iimfuno zoqoqosho.Nangona kunjalo, amalaphu adibeneyo e-polyester-cotton asasazwa kwaye adayiwe kumaqondo aphezulu.Phakathi, ngenxa yokudityaniswa komqhaphu okanye i-rayon fiber, kwaye iqondo lobushushu lokudaya alinakuba phezulu kunobushushu belaphu lepolyester.Nangona kunjalo, iingubo ze-polyester-cotton okanye i-polyester-cotton rayon, phantsi kokuvuselela i-alkali eqinile okanye i-sodium hydroxide, iya kubangela ukuba amandla e-fiber okanye amandla okukrazula awele kakhulu, kwaye kunzima ukufezekisa umgangatho wemveliso kwiikhonkco ezilandelayo.

Inkqubo yokufuduka kwe-thermal yeedayi ezisasazwayo inokuchazwa ngolu hlobo lulandelayo:

1. Kwinkqubo yokudaya ubushushu obuphezulu, ukwakheka kwefiber yepolyester iyakhululeka, idayi yokusasaza isasazeke ukusuka kumphezulu wefiber ukuya ngaphakathi kwifiber, kwaye isebenza ikakhulu kwifiber yepolyester ngebhondi ye-hydrogen, umtsalane we-dipole kunye ne-van der. Waals amandla.

2. Xa ifayibha edayiweyo iphantsi konyango lobushushu obuphezulu, amandla ashushu anika amandla okusebenza okuphezulu kwikhonkco elide lepolyester, eliqinisa ukungcangcazela kwetsheyina lemolekyuli, kwaye i-microstructure yefiber iphinda iphumle, okukhokelela ekudibaneni phakathi. ezinye iimolekyuli zedayi kunye netsheyina elide lepolyester Yaba buthathaka.Ke ngoko, ezinye iimolekyuli zedayi ezinamandla okusebenza okuphezulu kunye nenqanaba eliphezulu lokuzimela zifuduka zisuka ngaphakathi kwifayibha ziye kumaleko womphezulu wefayibha ezinolwakhiwo olukhululekileyo, zidibanise nomphezulu wefayibha ukwenza idayi yomaleko womphezulu.

3. Ngexesha lovavanyo lokukhawuleza olumanzi.Idayi ezingaphezulu ezingabotshwanga ngokuqinileyo, kunye needayi ezinamathele kwi-cotton sticky component, ziya kushiya kalula i-fiber ukuba ingene kwisisombululo kwaye ingcolise ingubo emhlophe;okanye ubambelele ngokuthe ngqo kwilaphu elimhlophe lovavanyo ngokuhlikihla, ngaloo ndlela ubonisa ukuqina okumanzi kunye nokukhuhlana kwemveliso edayiweyo ukukhawuleza kuyancipha.
