Ukusasaza inkqubo yokuDaya

Xa udaya kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu.Ukusasaza inkqubo yokudaya yefiber yepolyester.

Yahlulahlulwe yangamanqanaba amane

1. Ukusasaza iidayi zifuduka ukusuka kwisisombululo sedayi ukuya kumphezulu wefayibha ngenxa yomahluko wokugxila:

2. Iidayi ezisasazwayo zibhengezwa kumphezulu wefiber:

3. Ukusasaza idayi ingena kwifiber:

4. Ukusasaza idayi zifudukela ngaphakathi kwifayibha.

Ukwenzela ukufikelela kwisiphumo esihle somgangatho kunye nakwinkqubo yezi zigaba zine.

Ifomu yokusasaza idayi kwidayi yotywala kunye nefiber

Kuye kwenzeka utshintsho oluninzi:

Okokuqala, iidayi ezisasazwayo zihlakazwe kwisisombululo samanzi ngendlela yeengqungquthela (iimolekyuli ezininzi ze-crystal yedayi) ngokusebenzisa i-dispersant.Yenza inkqubo esasazekileyo.Okwesibini, njengoko iqondo lokushisa linyuka, ukuhamba kwe-thermal yee-molecule zedayi kuqinisa kwaye ngokuthe ngcembe kuhluke kwi-crystal state enye.Ekugqibeleni, idayi yokusabalalisa kwi-crystal state ingena kwi-fiber, idlulisa ngaphakathi kwefiber kwaye ifikelele kwi-equilibrium.Iimolekyuli zedayi kutywala bedayi ngokuqhubekayo zingena kwifiber, kwaye inxalenye ethile yedayi esasazekayo kwifiber idluliselwa kwifayibha ukuya kwidayi yotywala.

Ukudaya kulungelelaniswa kuwo onke amanqanaba enkqubo yokudaya kwiidayi ezisasazwayo.Kuya kuhlala kukho idayi enye-crystal disperse dyes xa befumana amandla okwaneleyo ukukrazula kuthintelo lwe-dispersant kunye nokudibanisa kunye nezinye ii-crystal-disperse dyes ukwenza iikristale ezinkulu (okanye i-recrystallization), xa iikristali ezihlaziyiweyo zikhulu ngokwaneleyo.Amabala edayi okanye amabala aya kwenziwa, anokuphucula iqondo leplastiki yefiber, eya kunceda inkqubo yokudaya igqitywe ngokukhawuleza.Ukongezelela, i-solubility ye-disperse dyes emanzini iphantsi kakhulu, kwaye iidayi kwi-dayi yotywala kufuneka zihlakazwe kwindawo yokuhlamba idayi njengento yokunqunyanyiswa ngobuninzi be-dispersant xa udaya iifayili ze-polyester.Ukuze ufezekise umphumo ongcono wokudaya, inani elithile lokuncedisa ukudaya lidla ngokudibaniswa.

Indima yokudaya abancedisi kwinkqubo yokudaya

a.Yandisa ngokufanelekileyo ukunyibilika kweedayi ezisasazwayo:

b.Yazisa ukuthengiswa kweedayi ezisasazekileyo kumphezulu wefiber:

c.Yenza i-fiber ngeplastiki okanye unyuse izinga lokudumba.Ukukhawulezisa isantya sokusasazwa kwedayi kwifiber:

d.Phucula uzinzo lokusasazeka kwedayi.

Ngokubanzi, izinto ezincedisayo ezisetyenziselwa ukudaya okuphezulu kobushushu kunye noxinzelelo oluphezulu lwemicu yepolyester ziqulathe umthwali owenza iplastiki ifake ifayibha, i-agent esebenzayo emphezulu enyibilikisa iidayi ezisasaza okanye izinzise ukunqunyanyiswa kwedayi, kunye nezinye izinto ezincedisayo zokudaya zinefuthe elibaluleke kakhulu ukudaywa kweentsinga zepolyester.
