Indlela yokuthuthukisa ukushesha kokudaya kwezindwangu eziphrintiwe nezidaywe ukuze kuhlangatshezwane nesidingo semakethe yezindwangu esikhula ngamandla isibe yisihloko socwaningo embonini yokunyathelisa nokudaya. Ikakhulukazi, ukushesha okulula kwamadayi asabelayo ezindwangu ezinombala okhanyayo, ukushesha kokuhlikihla okumanzi kwezindwangu ezimnyama neziminyene; ukwehla kokushesha kokulashwa okumanzi okubangelwa ukufuduka kokushisa kwamadayi ahlakazekile ngemva kokudaya; kanye nokushesha okuphezulu kwe-chlorine, ukushesha kokujuluka nokukhanya Ukushesha njll.

Kunezici eziningi ezithinta ukushesha kombala, futhi kunezindlela eziningi zokuthuthukisa ukushesha kombala. Eminyakeni eminingi yokusebenza kokukhiqiza, ochwepheshe bokunyathelisa nokudaya baye bahlola ekukhetheni izithasiselo ezifanele zokudaya namakhemikhali, ukuthuthukiswa kokudaya nezinqubo zokuqeda, kanye nokuqinisa ukulawula inqubo. Ezinye izindlela nezinyathelo ziye zasetshenziswa ukwandisa nokuthuthukisa ukushesha kombala ngezinga elithile, okuhlangabezana nesidingo semakethe.

Ukuqina okulula kwamadayi asabelayo izindwangu ezinombala okhanyayo

Njengoba sonke sazi, amadayi asabelayo adayiwe kumafayibha kakotini ahlaselwa imisebe ye-ultraviolet ngaphansi kokukhanya kwelanga, futhi ama-chromophores noma ama-auxochrome esakhiweni sedayi azolimala ngamazinga ahlukahlukene, okuholela ekushintsheni kombala noma umbala okhanyayo, okuyinkinga yokushesha kokukhanya.

Izindinganiso zikazwelonke zezwe lami sezivele zibeke ukuqina okulula kwamadayi asebenzayo. Isibonelo, indinganiso yendwangu yokunyathelisa nokudaya ikotini ye-GB/T411-93 ithi ukuqina okulula kwamadayi asebenzayo kungu-4-5, kanti ukuqina okulula kwezindwangu ezinyathelisiwe kungu-4; indinganiso yendwangu yokunyathelisa nokudaya ehlanganisiwe ye-polyester-cotton ye-GB /T5326 kanye nendinganiso yendwangu yokunyathelisa nokudaya ehlanganisiwe ye-FZ/T14007-1998 ikotini-polyester ehlanganisiwe kokubili kubeke ukuqina okulula kwendwangu edayiwe ehlakazekile/esabelayo kuyizinga lesi-4, kanti indwangu enyathelisiwe nayo iyizinga lesi-4. Kunzima ngamadayi asebenzayo ukudaya izindwangu ezinyathelisiwe ezinombala okhanyayo ukuze kuhlangatshezwane naleli zinga.

Ubudlelwano phakathi kwesakhiwo se-dye matrix kanye nokushesha kokukhanya

Ukuqina kokukhanya kwamadayi aphendulayo kuhlobene kakhulu nesakhiwo se-matrix sedayi. Ama-70-75% esakhiwo se-matrix samadayi aphendulayo uhlobo lwe-azo, kanti amanye angohlobo lwe-anthraquinone, uhlobo lwe-phthalocyanine kanye nohlobo lwe-A. Uhlobo lwe-azo alunamandla okukhanya aphansi, kanti uhlobo lwe-anthraquinone, uhlobo lwe-phthalocyanine, kanye nezinzipho zinokuqina kokukhanya okungcono. Isakhiwo sama-molecule samadayi aphendulayo aphuzi uhlobo lwe-azo. Imizimba yombala womzali yi-pyrazolone kanye ne-naphthalene trisulfonic acid ukuze kube nokuqina kokukhanya okungcono kakhulu. Amadayi aphendulayo e-blue spectrum yi-anthraquinone, i-phthalocyanine, kanye nesakhiwo somzali. Ukuqina kokukhanya kuhle kakhulu, kanti isakhiwo sama-molecule sedayi ephendulayo ye-red spectrum uhlobo lwe-azo.

Ukuqina kokukhanya ngokuvamile kuphansi, ikakhulukazi ngemibala ekhanyayo.

Ubudlelwano phakathi kobuningi bokudaya kanye nokuqina kokukhanya
Ukuqina kokukhanya kwamasampula adaywe kuzohluka ngokushintsha kokuhlushwa kokudayi. Kumasampula adaywe ngodayi ofanayo ku-fiber efanayo, ukuqina kwawo kokukhanya kuyanda ngokwanda kokuhlushwa kokudayi, ikakhulukazi ngoba idayi ingaphakathi. Kubangelwa izinguquko ekusabalaleni kosayizi wezinhlayiya ezihlanganisiwe ku-fiber.

Uma izinhlayiya ezihlanganisiwe zinkulu, indawo ngayinye yesisindo sedayi evezwe emswakama emoyeni iba ncane, futhi ukukhanya kushesha kakhulu.
Ukwanda kokuhlushwa kokudaya kuzokwandisa isilinganiso sama-aggregate amakhulu ku-fiber, futhi ukushesha kokukhanya kuzokwanda ngokufanele. Ukuhlushwa kokudaya kwezindwangu ezinombala okhanyayo kuphansi, kanti isilinganiso sama-aggregate e-fiber siphansi. Iningi lamadayi lisesimweni se-molecule eyodwa, okungukuthi, izinga lokubola kwedayi ku-fiber liphezulu kakhulu. I-molecule ngayinye inethuba elifanayo lokudalulwa ekukhanyeni nasemoyeni. , Umphumela womswakama, ukushesha kokukhanya nakho kwehla ngokufanele.

I-ISO/105B02-1994 ukushesha kokukhanya okujwayelekile kuhlukaniswe ngokuhlolwa okujwayelekile kwebanga eli-1-8, izinga likazwelonke lezwe lami lihlukaniswe ngokuhlolwa okujwayelekile kwebanga eli-1-8, i-AATCC16-1998 noma i-AATCC20AFU ukushesha kokukhanya okujwayelekile kuhlukaniswe ngokuhlolwa okujwayelekile kwebanga eli-1-5.

Izinyathelo zokuthuthukisa ukushesha kokukhanya

1. Ukukhetha udayi kuthinta izindwangu ezinombala okhanyayo
Isici esibaluleke kakhulu ekuqineni kokukhanya yidayi uqobo lwayo, ngakho-ke ukukhetha idayi kubaluleke kakhulu.
Uma ukhetha amadayi okufanisa imibala, qiniseka ukuthi izinga lokuqina kokukhanya kwedayi ngayinye yengxenye ekhethiwe lilingana, uma nje noma iyiphi yezingxenye, ikakhulukazi ingxenye enenani elincane, ingakwazi ukufinyelela ukuqina kokukhanya kwendwangu edaywe ngombala okhanyayo. Izidingo zendwangu yokugcina edaywe ngeke zihlangabezane nendinganiso yokuqina kokukhanya.

2. Ezinye izindlela
Umphumela wamadayi antantayo.
Ukudaya nokusula akuphelele, futhi amadayi angakaqini kanye namadayi afakwe i-hydrolyzed asele endwangu kuzothinta nokuqina kokukhanya kwento edayiwe, futhi ukuqina kwawo kokukhanya kuphansi kakhulu kunokwamadayi aguquguqukayo aqinile.
Uma kwenziwa insipho ngokucophelela, kulapho ukukhanya kushesha khona.

Ithonya le-fixing agent kanye ne-softener.
I-Cationic low-molecular-weight noma i-polyamine-condensed resin type fixing agent kanye ne-cationic softener zisetshenziswa ekuqedeni indwangu, okuzonciphisa ukushesha kokukhanya kwemikhiqizo edaywe.
Ngakho-ke, lapho ukhetha izinto zokulungisa kanye nezinto zokuthambisa, kufanele kuqashelwe ithonya lazo ekuqineni okulula kwemikhiqizo edayiwe.

Ithonya lezifutho ze-UV.
Izifutho ze-ultraviolet zivame ukusetshenziswa ezindwangu ezidaywe ngombala okhanyayo ukuze kuthuthukiswe ukushesha kokukhanya, kodwa kumele zisetshenziswe ngobuningi ukuze zibe nomthelela othile, okungagcini nje ngokwandisa izindleko, kodwa futhi okubangela ukuphuzi kanye nomonakalo omkhulu endwangu, ngakho-ke kungcono ukungasebenzisi le ndlela.
