Iidayi ezisasazwayo zinokusetyenziswa kubugcisa obahlukeneyo kwaye ngokulula kunokufaka imibala kwimidibaniso engalunganga eyenziwe ngeedayi ezisasazwayo, njengepolyester, inayiloni, i-cellulose acetate, i-viscose, ivelvet yokwenziwa, kunye nePVC.Zisenokusetyenziswa ukufaka imibala kumaqhosha eplastiki kunye neziqhoboshi.Ngenxa yesakhiwo se-molecular, banempembelelo ebuthakathaka kwi-polyester, kwaye ivumela kuphela imibala ye-pastel ukuba idlule kwiitoni eziphakathi.Iifayili zepolyester zinemingxuma okanye iibhubhu kwisakhiwo sabo.Xa ishushu kwi-100 ° C, imingxuma okanye iibhubhu zanda ukuze kungene amasuntswana edayi.Ukwandiswa kwee-pores kunqunyelwe ukushisa kwamanzi - ukudaya kweshishini le-polyester kwenziwa kwi-130 ° C kwizixhobo ezixinzelelekileyo!
Njengoko uLinda Chapman uthe, xa usebenzisa i-disperse dyes ukuhanjiswa kwe-thermal, umbala ogcweleyo unokufezekiswa.
Ukusetyenziswa kwedayi ezisasazwayo kwiintsinga zendalo (ezifana nomqhaphu kunye noboya) akusebenzi kakuhle, kodwa kunokusetyenziswa ngokudityaniswa ne-Reactive Dyeing ukwenza imixube yepolyester/cotton.Le teknoloji isetyenziswa kwishishini phantsi kweemeko ezilawulwayo.
Ukusasaza ukuDaya
Ukusasaza itekhnoloji yokuDaya:
Idayi i-100 grams yelaphu kwiilitha ezi-3 zamanzi.
Ngaphambi kokudaya, kubalulekile ukujonga ukuba ilaphu “likulungele ukudaywa” (PFD) okanye lifuna ukukhuhlwa ukuze lisuse igrisi, igrisi okanye isitatshi.Beka amathontsi ambalwa amanzi abandayo phezu ilaphu.Ukuba zifunxa ngokukhawuleza, akukho mfuneko yokuba zihlanjululwe.Ukususa isitashi, iintsini kunye negrisi, yongeza i-5 ml Synthrapol (i-non-ionic detergent) kunye ne-2-3 ilitha zamanzi kwi-100 grams yezinto.Gcoba ngobumnene imizuzu eyi-15, uze uhlambulule ngokucokisekileyo emanzini afudumeleyo.Izicoci zasemakhaya zingasetyenziswa, kodwa iintsalela zealkaline zinokuchaphazela umbala wokugqibela okanye ukukhawuleza kokuhlamba.
Fudumeza amanzi kwisitya esifanelekileyo (ungasebenzisi intsimbi, ubhedu okanye i-aluminium).Ukuba usebenzisa amanzi asuka kwiindawo ezinamanzi aqinileyo, yongeza i-3 grams yeCalgon ukunceda ukuphelisa i-alkalinity yayo.Ungasebenzisa iphepha lokuvavanya ukuvavanya amanzi.
Ukulinganisa umgubo wedayi ohlakaziweyo (i-0.4gm yombala okhanyayo kunye ne-4gm yombala omnyama), kwaye ufefe umlinganiselo omncinci wamanzi afudumeleyo ukwenza isisombululo.
Yongeza isisombululo sedayi kunye ne-3 grams ye-dispersant kwibhafu yedayi, kwaye ugxobhoze ngokucokisekileyo ngeplanga, insimbi engenasici okanye iplastiki.
Yongeza ilaphu kwibhafu yokudaya kwaye ushukumise ngobunono ngelixa unyusa ubushushu ukuya kwi-95-100 ° C ngaphakathi kwemizuzu eyi-15-30 (ukuba udaya i-acetate, gcina ubushushu kwi-85 ° C).Ilaphu lihlala ixesha elide kwibhafu yedayi, ubuninzi bomthunzi.
Vumela ukuhlamba kupholile kwi-50 ° C, uze ukhangele umbala.Yongeza isisombululo esingaphezulu sedayi ukwandisa amandla ayo, kwaye emva koko ukwandise ukushisa kwi-80-85 ° C imizuzu eyi-10.
Qhubeka kwisinyathelo sesi-5 de kube umbala ofunekayo ufunyenwe.
Ukugqiba le nkqubo, susa ilaphu kwibhafu yedayi, uyihlambulule emanzini afudumeleyo, ujikeleze owomileyo kunye nentsimbi.
Ukutshintshwa kwe-thermal usebenzisa i-disperse dyes kunye neengubo
Ukusasaza idayi zingasetyenziswa ekutshintsheni ushicilelo.Unokwenza iiprints ezininzi kwiintsinga zokwenziwa (ezifana nepolyester, inayiloni, noboya kunye nemixube yekotoni kunye nomxholo wefayibha yokwenziwa engaphezulu kwe-60%).Umbala weedayi ezisasazwayo uya kubonakala unqabile, kwaye kuphela emva kokuba usetyenziswe bubushushu banokubonisa umbala opheleleyo.Ukuvavanya kwangaphambili umbala kuya kunika isibonakaliso esihle sesiphumo sokugqibela.Umfanekiso apha ubonisa umphumo wokudluliselwa kwikotoni kunye neendwangu zepolyester.Ukusampula kuya kukunika ithuba lokujonga useto lwentsimbi kunye nexesha lokuhambisa.
