Indlela yokuthuthukisa ukushesha kokudaya kwezindwangu eziphrintiwe nezidayiwe ukuze kuhlangatshezwane nesidingo esikhulayo semakethe yendwangu sekuyisihloko socwaningo embonini yokunyathelisa nokudaya. Ikakhulukazi, ukushesha kokukhanya kodayi abasebenzayo ezindwangu ezinombala okhanyayo, ukushesha okumanzi kokuxubha kwezindwangu ezimnyama neziminyene; ukwehla kokushesha kokwelashwa okumanzi okubangelwa ukufuduka okushisayo kwamadayi ahlakazayo ngemva kokudaya; nokushesha kwe-chlorine ephezulu, ukushesha kokukhanya komjuluko njll.

Kunezici eziningi ezithinta ukushesha kombala, futhi kunezindlela eziningi zokuthuthukisa ukushesha kombala. Phakathi neminyaka yokusebenza kokukhiqiza, ochwepheshe bokunyathelisa nokudaya baye bahlola ekukhetheni izithasiselo ezifanele zokudaya kanye namakhemikhali, ukuthuthukiswa kwezinqubo zokudaya nokuqeda, kanye nokuqiniswa kokulawulwa kwenqubo. Ezinye izindlela nezinyathelo zamukelwe ukuze kwandiswe futhi kuthuthukiswe ukushesha kombala ngokwezinga elithile, elihlangabezana ngokuyisisekelo nesidingo semakethe.

Ukushesha okulula kodayi abasebenzayo izindwangu ezinombala okhanyayo

Njengoba sonke sazi, odayi abasebenzayo abadaywe emiculweni kakotini bahlaselwa imisebe ye-ultraviolet ngaphansi kokukhanya kwelanga, futhi ama-chromophores noma ama-auxochromes esakhiweni sikadayi azolimala ngamazinga ahlukahlukene, okuholela ekushintsheni kombala noma umbala okhanyayo, okuyinkinga yokushesha kokukhanya.

izindinganiso zezwe lami sezivele zikubeke kwacaca ukushesha kodayi abasebenzayo. Isibonelo, indinganiso ye-GB/T411-93 yokunyathelisa ukotini kanye nendwangu yokudaya ibeka ukuthi ukushesha kokukhanya kodayi abasebenzayo kungu-4-5, nokushesha kokukhanya kwezindwangu eziphrintiwe ku-4; I-GB /T5326 indinganiso yokuphrinta ehlanganisiwe ye-polyester-cotton ehlanganisiwe nendwangu yokudaya kanye nezinga le-FZ/T14007-1998 lendwangu ehlanganisiwe kakotini ne-polyester yokudaya kokubili kucacisa ukuthi ukushesha kokukhanya kwendwangu edayiwe ehlakazekile kukuleveli 4, nendwangu ephrintiwe nayo isezingeni. 4. Kunzima ukuthi odayi abasebenzayo badaye izindwangu eziphrintiwe ezinombala okhanyayo ukuze bahlangabezane naleli zinga.

Ubudlelwano phakathi kwesakhiwo se-matrix kadayi nokushesha kokukhanya

Ukushesha kokukhanya kodayi abasebenzayo ikakhulukazi kuhlobene nesakhiwo se-matrix sikadayi. U-70-75% wesakhiwo se-matrix sikadayi osebenzayo uwuhlobo lwe-azo, kanti okunye kuwuhlobo lwe-anthraquinone, uhlobo lwe-phthalocyanine nohlobo luka-A. Uhlobo lwe-azo lunokushesha kokukhanya okubi, futhi uhlobo lwe-anthraquinone, uhlobo lwe-phthalocyanine, kanye nezipikili zinokushesha okungcono kokukhanya. Isakhiwo samangqamuzana odayi abaphuzi abasebenzayo uhlobo lwe-azo. Imizimba yombala yomzali yi-pyrazolone ne-naphthalene trisulfonic acid yokushesha kokukhanya okungcono kakhulu. Odayi be-blue spectrum abasebenzayo yi-anthraquinone, i-phthalocyanine, kanye nesakhiwo somzali. Ukushesha kokukhanya kuhle kakhulu, futhi ukwakheka kwamangqamuzana odayi obomvu we-spectrum osebenzayo kuwuhlobo lwe-azo.

Ukushesha kokukhanya ngokuvamile kuphansi, ikakhulukazi ngemibala ekhanyayo.

Ubudlelwano phakathi kokuminyana kokudaya nokushesha kokukhanya
Ukushesha kokukhanya kwamasampuli adayiwe kuzohluka ngokushintsha kokugxilisa kokudaya. Kumasampuli adayiwe ngodayi ofanayo kwifayibha efanayo, ukushesha kokukhanya kwawo kuyanda ngokukhula kokugxilisa kokudaya, ikakhulukazi ngoba udayi uku-Kubangelwa izinguquko kusayizi wokusabalalisa izinhlayiya ezihlanganisiwe ku-fiber.

Uma izinhlayiya ezihlanganisiwe ziba zinkulu, indawo encane ngeyunithi ngayinye yesisindo sikadayi evezwe kumswakama womoya, kanye nokunyuka kokushesha kokukhanya.
Ukwanda kokugxila kokudaya kuzokwandisa ingxenye yama-aggregates amakhulu ku-fiber, futhi ukushesha kokukhanya kuzokhula ngokufanele. Ukugxilwa kokudaya kwezindwangu ezinemibala ekhanyayo kuphansi, futhi ingxenye yokuhlanganiswa kodayi ku-fiber iphansi. Odayi abaningi basesimweni se-molecule eyodwa, okungukuthi, izinga lokubola likadayi ku-fiber liphezulu kakhulu. I-molecule ngayinye inethuba elifanayo lokuchayeka ekukhanyeni nasemoyeni. , Umphumela womswakama, ukushesha kokukhanya nakho kunciphisa ngokufanele.

I-ISO/105B02-1994 ukushesha kokukhanya okujwayelekile ihlukaniswe yaba ukuhlolwa okujwayelekile kwebanga le-1-8, izinga likazwelonke lezwe lami lihlukaniswe ngokuhlolwa okujwayelekile kwebanga le-1-8, i-AATCC16-1998 noma i-AATCC20AFU ukushesha kokukhanya okujwayelekile ihlukaniswe yaba ukuhlolwa okujwayelekile kwebanga elingu-1-5. .

Izinyathelo zokuthuthukisa ukushesha kokukhanya

1. Ukukhethwa kodayi kuthinta izindwangu ezinombala okhanyayo
Isici esibaluleke kakhulu ekukhanyeni ukukhanya yidayi ngokwayo, ngakho-ke ukukhethwa kwedayi kubaluleke kakhulu.
Uma ukhetha odayi bokufanisa umbala, qiniseka ukuthi izinga lokushesha kokukhanya lodayi ngamunye wengxenye ekhethiwe liyalingana, inqobo nje uma noma iyiphi ingxenye, ikakhulukazi ingxenye enenani elincane, ayikwazi ukufinyelela ukushesha kokukhanya kombala okhanyayo. impahla edayiwe Izidingo zezinto zokugcina ezidayiwe ngeke zihlangabezane nezinga lokushesha kokukhanya.

2. Ezinye izinyathelo
Umthelela wodayi abantantayo.
Ukudaya kanye nensipho akuphelele, futhi odayi abangalungisiwe kanye nodayi be-hydrolyzed abasele engutsheni bazophinde bathinte ukukhanya kwento edayiwe, futhi ukushesha kwabo kokukhanya kuphansi kakhulu kunodayi abasebenzayo abangaguquki.
Uma insipho yenziwa ngokucophelela, kuba ngcono ukushesha kokukhanya.

Umthelela we-ejenti yokulungisa nesithambisa.
I-Cationic low-molecular-weight noma i-polyamine-condensed resin type fixing agent kanye nesithambile se-cationic kusetshenziswa ekuqedeni indwangu, okuzonciphisa ukushesha kokukhanya kwemikhiqizo edayiwe.
Ngakho-ke, lapho kukhethwa ama-ejenti okulungisa kanye nezinto ezithambisayo, kufanele kuqashelwe ithonya labo ekukhanyeni kokukhanya kwemikhiqizo edayiwe.

Ithonya lama-absorbers e-UV.
Ama-absorber e-Ultraviolet avame ukusetshenziselwa izindwangu ezidayiwe ezinemibala ekhanyayo ukuze kuthuthukiswe ukushesha kokukhanya, kodwa kufanele asetshenziswe ngenani elikhulu ukuze abe nomphumela othile, okungagcini nje ukwandisa izindleko, kodwa futhi kubangela ukulimala okuphuzi nokuqina kwendwangu, ngakho-ke kungcono ukungasebenzisi le ndlela.
