Uphuhliso lweTekhnoloji yokuDaya eReactive

Kwiminyaka yakutshanje, inkqubo entsha yokudaya ye-reactive dyeing iphuhliswe ngokukhawuleza.Inkqubo yangoku yokudaya esebenzayo ibandakanya: ukudaya kwedayi esebenzayo kunye nokudaya komphunga omfutshane, idayi esebenzayo yediphu yokudaya inkqubo emfutshane, idayi esebenzayo yobushushu obuphantsi kunye nokudaya kwebhetshi ebandayo, kunye nokudaya kwe-agent engathathi hlangothi, idayi esebenzayo enetyuwa encinci kunye nokudaya okungenatyuwa, sebenzisa "ityuwa ebambeleyo" idayi esebenzayo yokudaya enetyuwa encinci, idayi esebenzayo enealkali encinci kunye nokudaya okungathathi hlangothi.

1.Ukudaya iphedi yedayi esebenzayo kunye nokudaya komphunga omfutshane omanzi.Ukudaya ngeepadi yenye yeendlela ezibalulekileyo zokudaya iidayi ezisebenzayo.Nangona kunjalo, emva kokuba ilaphu lifakwe kwisisombululo sedayi ye-pad, ukumisa okuphakathi kuyafuneka ukuze kuququzelele i-steaming elandelayo, okanye ukwandisa isantya sokucubungula ngexesha lokubhaka kunye nokulungiswa.Kwaye unciphise i-hydrolysis yedayi, kwaye ufumane izinga eliphezulu lokulungiswa kunye nokukhawuleza kombala.Ukomisa okuphakathi kuya kuzisa iingxaki ezininzi: ukusetyenziswa kwamandla, umthamo omkhulu wamandla okushisa asetyenziswa xa usoma amalaphu amanzi ukuze aphephe amanzi;iidayi zidla ngokufuduka ngexesha lokumisa, okukhokelela kumbala ohlukileyo kunye nokuncipha kokukhawuleza kombala, kwaye ukuphinda kuphinde kuveliswe ukudaya kubi;Ukomisa emva kokuntywila isisombululo sokudaya akugcini nje ukongeza inkqubo yokucubungula kwaye kungenakulungeleka ukulawula, kodwa naxa i-cloth eyomileyo iqhutywe, iidayi kunye neekhemikhali kufuneka zifunxe amanzi ukuze zichithe kwakhona.Ilaphu elomileyo liya kukhupha ubushushu xa lifunxa umswakama, okukhokelela ekushiseni, okuyonakalisa ukudaya nokulungiswa.Ngoko ke, ukutshaya kuyinjongo yexesha elide abantu abayifunayo.Kunzima kakhulu ukwenza amalaphu adaywe ngomphunga.Okokuqala, ilaphu elimanzi liqhunyiswa ngokuthe ngqo.Ngenxa yokuba umswakama uthatha ubushushu kwaye uphuphe, izinga lokufudumeza kwelaphu liyancipha, elongeza ixesha lokutshisa kunye nokulungisa;okwesibini, ilaphu liqulethe ubuninzi bomswakama (ngokuqhelekileyo umlinganiselo we-liquid emva kwe-padding yi-60% ukuya kwi-70%), kwinkqubo yokutshisa kunye nokufudumeza, iidayi ezisebenzayo kwilaphu ziya kuba nexabiso elikhulu le-hydrolysis, elinciphisa ukulungiswa. izinga kunye nokukhawuleza kombala.Ukufuma kwelaphu kunamazwe amaninzi, anokuthi ahlulwe ngokweendidi ezimbini: ifayibha efunxa amanzi kunye namanzi asimahla kwelaphu.Amanzi abotshelelwe ngokwekhemikhali afunxa amanzi (ikakhulu adityaniswe kwikhonkco le-fiber molecular chain ngokusebenzisa i-hydrogen bonds) ikwabizwa ngokuba ngamanzi angakhenkcezisi (indawo yokukhenkceza ingaphantsi kakhulu kuno-0°C).Le nxalenye yomxholo wamanzi ayininzi, kwaye amathuba okuphendula ngeedayi nawo angaphantsi, kuba Akwazi ukuhamba ngokukhululekile.Inxalenye enkulu yamanzi afunxayo ikwimibhobho yefiber.Ifiber pores zibhityile kakhulu.Le ndawo yamanzi ayilula ukuhamba ngokukhululekileyo, ngoko ikwabizwa ngokuba ngamanzi abophekileyo.Izinga lokusabela kwayo ngeedayi nalo liphantsi.Nangona inxalenye yamanzi akhululekile ngaphandle kwefiber kwi-capillary inter-fiber kwaye akulula ukuhamba ngenxa yempembelelo ye-capillary, ininzi yayo inokuhamba ngokukhululekile.Amanzi kula mazwe mabini ngaphandle kwefiber kulula ukusabela ngedayi.Xa idayi iphezulu, kufuneka ukuba idayi ingabikho kwinani elikhulu le-hydrolysis, kwaye ukusabela kokulungiswa ngokukhawuleza kwenzeka emva kokufikelela kubushushu obuphezulu ngokwaneleyo.Ngenxa yesi sizathu, i-alkali elungele ukusetyenziswa kufuneka ibe buthathaka, okanye i-alkalinity ayifanele yomelele xa isiqulatho sokufuma kwelaphu siphezulu (kubandakanywa nealkali exutyiweyo yesoda yokubhaka okanye i-soda ash kunye nezinye ii-alkali agents), ukuba ialkali iphantsi. okanye ukulungiswa kokungathathi hlangothi kwenziwa Umphumo uya kuba ngcono.Uphononongo lufumene ukuba ukusetyenziswa kwearhente yokulungisa engathathi hlangothi ukulungisa umbala kunesiphumo esihle kwi-120～130℃ okanye 180℃.

I-2.Inkqubo emfutshane esebenzayo yedayi yokudaya inciphisa inkqubo yokudaya esebenzayo, iphucula ukusebenza kakuhle kwemveliso, igcina amandla, igcina amanzi, kwaye inciphisa ukukhutshwa kwamanzi amdaka.Ukudaya ngomphunga omfutshane omanzi yinkqubo emfutshane yokudaya ukudaya kweepadi.Inkqubo yokudaya emfutshane yokudaya idiphu ikwagxininise kuphando kwiminyaka yakutshanje, ukuphucula izixhobo, ukunciphisa ixesha lokudaya, kwaye okona kubaluleke kakhulu, ulawulo olufanelekileyo lwenkqubo yokudaya, kunye nolawulo oluzenzekelayo lwekhompyuter lunokunciphisa ukudaya, ukulungisa kunye nokuhlamba. ixesha.Kwiminyaka yakutshanje, iinkampani ezininzi ezivelisa idayi ziye zavelisa inkqubo yokudaya ekhawulezayo ukuze zithengise iimveliso zazo.Isiseko senkqubo yokudaya ngokukhawuleza kukukhetha iidayi ngokufanelekileyo ngokweempawu zabo, kunye nokunciphisa lonke ixesha lokudaya phantsi kwesiseko sokuqinisekisa ukulinganisa okulungileyo kunye nokuveliswa kwakhona.Thatha ukulinganisa okulawulwayo kunye nokudibanisa okuqhubekayo, okunokunciphisa ixesha.Kakhulu gcina idayi, i-alkalis kunye netyuwa, kwaye unciphise ukukhutshwa kwamanzi amdaka.Ezinye iinkqubo zikwalawula ngokuzenzekelayo ukuhlanjwa emva kokudaya ukonga ngakumbi amanzi kunye nokunciphisa ugutyulo.Abanye abenzi bedayi okanye izixhobo baye baphuhlisa inkqubo yokudaya eyahlukahlukeneyo elawulwayo.
