Ukuthuthukiswa kwe-Reactive Dyeing Technology
Eminyakeni yamuva nje, inqubo entsha yokudaya yokudaya ithuthuke ngokushesha.Izinqubo zamanje zokudaya ezisebenzayo zihlanganisa: ukudaya kwephedi likadayi osebenzayo kanye nokudaya okufushane ngesitimu, inqubo emfishane yediphu yediphu, udayi osebenzayo osebenzayo nezinga lokushisa eliphansi lenqwaba yokudaya, kanye nokudaya kwe-ejenti yokulungisa engathathi hlangothi , Udayi osebenzayo onosawoti omncane kanye nokudaya ongenawo usawoti, sebenzisa udayi “obambele kasawoti” osebenzayo wokudaya onosawoti omncane, udayi osebenzayo one-alkali ephansi kanye nokudaya okumaphakathi.
1.Ukudaya kwephedi likadayi okusebenzayo kanye nokudaya okufushane kwesitimu okumanzi.Ukudaya amaphedi kungenye yezindlela ezibalulekile zokudaya odayi abasebenzayo.Kodwa-ke, ngemva kokuba indwangu ifakwe ngesisombululo sedayi ye-pad, ukoma okuphakathi kuyadingeka ukuze kube lula ukuthungatha okulandelayo, noma ukwandisa isivinini sokucubungula ngesikhathi sokubhaka nokulungisa.Futhi unciphise i-hydrolysis yodayi, futhi uthole izinga eliphezulu lokulungisa nokushesha kombala.Ukomisa okuphakathi kuzoletha izinkinga eziningi: ukusetshenziswa kwamandla, inani elikhulu lamandla okushisa liyasetshenziswa lapho kumiswa izindwangu ezimanzi ukuze kuhwamuke amanzi;odayi bajwayele ukufuduka ngesikhathi somiswa, okuholela ekuhlukeni kombala kanye nokunciphisa ukushesha kombala, futhi ukuphindaphinda kokudaya nakho kumpofu;Ukomisa ngemva kokucwilisa isisombululo sokudaya akugcini nje ukwengeza inqubo yokucubungula futhi akulula ukuphatha, kodwa futhi lapho indwangu eyomile ifakwe isitimu, amadayi namakhemikhali kufanele amunce amanzi ukuze aphinde ahlakazeke.Indwangu eyomile izokhipha ukushisa lapho ibamba umswakama, okuholela ekushiseni, okulimaza ukudaya nokulungisa.Ngakho-ke, ukuthungatha umusi kuwumgomo wesikhathi eside abantu abawuphishekelayo.Kunzima kakhulu ukufaka izindwangu ezidayiwe ngesitimu.Okokuqala, indwangu emanzi i-steamed ngokuqondile.Ngenxa yokuthi umswakama ubamba ukushisa futhi uyahwamuka, izinga lokushisa kwendwangu liyancipha, okwandisa isikhathi sokushisa nokulungisa;okwesibili, indwangu iqukethe umswakama omningi (ngokuvamile izinga le-liquid ngemva kokupakisha liyi-60% kuya ku-70%), ngesikhathi sokushisa nokushisa, ama-dyes asebenzayo endwangu azobhekana nenani elikhulu le-hydrolysis, okunciphisa ukulungiswa. isilinganiso nokushesha kombala.Umswakama wendwangu unezifunda eziningi, ezingahlukaniswa cishe zibe izigaba ezimbili: amanzi afakwe i-fiber kanye namanzi amahhala endwangu.Amanzi aboshwe ngamakhemikhali amunca amanzi (ikakhulukazi ahlanganiswe neketango le-fiber molecular ngokusebenzisa i-hydrogen bond) abizwa nangokuthi amanzi angaqandisi (indawo yawo yokubanda iphansi kakhulu kuno-0°C).Le ngxenye yokuqukethwe kwamanzi ayiningi, futhi amathuba okusabela ngamadayi nawo angaphansi, ngoba Akwazi ukuhamba ngokukhululekile.Ingxenye enkulu yamanzi amuncwa isezimbotsheni zefiber.Ama-fiber pores mancane kakhulu.Le ngxenye yamanzi akulula ukugeleza ngokukhululeka, ngakho ibizwa nangokuthi amanzi abophekile.Izinga layo lokusabela ngodayi nalo liphansi.Nakuba ingxenye yamanzi amahhala ngaphandle kwefayibha iku-inter-fiber capillary futhi akulula ukugeleza ngenxa yomphumela we-capillary, iningi lawo lingageleza ngokukhululeka.Amanzi akulezi zifunda ezimbili ngaphandle kwefayibha kulula ukusabela ngodayi.Uma udayi uphakeme, kuyadingeka ukuthi udayi ungatholi inani elikhulu le-hydrolysis, futhi ukusabela kokulungiswa okusheshayo kwenzeka ngemva kokufinyelela izinga lokushisa eliphakeme ngokwanele.Ngenxa yalesi sizathu, i-alkali efanelekile ukusetshenziswa kufanele ibe buthakathaka, noma i-alkalinity akufanele ibe namandla uma okuqukethwe komswakama wendwangu kuphezulu (kuhlanganise ne-alkali exubile ye-baking soda noma i-soda ash namanye ama-alkali agents), uma i-alkali iphansi. noma ukulungiswa kokungathathi hlangothi kwenziwa Umphumela uzoba ngcono.Ucwaningo luthole ukuthi ukusetshenziswa kwe-ejenti yokulungisa engathathi hlangothi ukulungisa umbala kunomthelela omuhle kokuthi 120～130℃ noma 180℃.
I-2.Inqubo yokudaya yediphu esebenzayo emfushane yenza kube mfushane inqubo yokudaya esebenzayo, ithuthukisa ukusebenza kahle kokukhiqiza, yonga amandla, yonga amanzi, futhi inciphisa ukukhishwa kwendle.Ukudaya okufushane kwesitimu okumanzi kuyinqubo emfushane yokudaya yokudaya amaphedi.Inqubo yokudaya i-short-flow ye-dip dyeing nayo igxile ocwaningweni eminyakeni yamuva nje, ukuthuthukisa imishini, ukunciphisa isikhathi sokudaya, futhi okubaluleke nakakhulu, ukulawula okunengqondo kwenqubo yokudaya, kanye nokulawulwa kwekhompyutha okuzenzakalelayo kunganciphisa ukudaya, ukulungisa nokugeza. isikhathi.Eminyakeni yamuva, izinkampani eziningi ezikhiqiza udayi ziye zasungula izinqubo zokudaya ngokushesha ukuze zithuthukise imikhiqizo yazo.Isisekelo senqubo yokudaya ngokushesha ukukhetha odayi ngokufanelekile ngokwezici zabo, kanye nokunciphisa sonke isikhathi sokudaya ngaphansi kwesisekelo sokuqinisekisa izinga elihle nokukhiqizwa kabusha.Thatha ukulinganisa okulawulwayo kanye nokwengeza okuqhubekayo, okunganciphisa isikhathi.Kakhulu yonga odayi, ama-alkali nosawoti, futhi unciphise ukukhishwa kwendle.Ezinye izinqubo ziphinde zilawule ngokuzenzakalelayo ukugeza ngemva kokudaya ukuze kuqhubeke ukonga amanzi nokunciphisa indle.Abanye abakhiqizi bakadayi noma amathuluzi baye basungula isofthiwe ehlukahlukene elawulwayo yokudaya.
Singabahlinzeki be-Reactive Dyeing.Uma unentshisekelo ngemikhiqizo yethu, sicela ukhululeke ukuxhumana nathi.
