Maitiro ekuvandudza kukurumidza kwekudhaya kweakadhindwa uye akadhayiwa machira kuti asangane nekuwedzera anotyisa kudiwa kwemusika wemucheka wave musoro wekutsvagisa muindasitiri yekudhinda nekudhaya. Kunyanya, kukurumidza kwechiedza chemavara anogadzirisa kune machira akajeka-mavara, kunyorova kwekutsvaira kwemachira akasviba uye akaomeswa; kuderera kwekunyorova kwekurapa nekukurumidza kunokonzerwa nekufamba kwemafuta ekuparadzira dhayi mushure mekudhaya; uye yakakwirira chlorine kutsanya, ziya-chiedza kutsanya Kutsanya nezvimwe.

Pane zvinhu zvakawanda zvinokanganisa kukurumidza kwemavara, uye kune nzira dzakawanda dzekuvandudza kukurumidza kwemavara. Kupfuura makore ekudzidzira kwekugadzira, kudhinda uye kudhaya varapi vakaongorora mukusarudzwa kweakakodzera dhayi uye makemikari ekuwedzera, kuvandudzwa kwekudhaya uye kupedzisa maitiro, uye kusimbaradza kwekutonga kwemaitiro. Dzimwe nzira uye nhanho dzakagamuchirwa kuti dziwedzere nekuvandudza kukurumidza kwemavara kune imwe nhanho, izvo zvinosangana nezvinodiwa zvemusika.

Light fastness ye reactive dyes machira ane mavara-mavara

Sezvatinoziva tose, dhayi dzinoshanda dzakadhayiwa pashinda dzedonje dzinorwiswa nemwaranzi ye ultraviolet pasi pezuva, uye chromophores kana auxochromes muchimiro chedhayi ichakuvadzwa kune akasiyana madhigirii, zvichikonzera shanduko yemavara kana ruvara rwakareruka, inova Chiedza fastness dambudziko.

hunhu hwenyika yangu hwakatotaura kutsanya kwedhayi dzinoshanda. Semuenzaniso, iyo GB/T411-93 donje yakadhindwa uye yekudhaya jira rejira inotaridza kuti kukurumidza kukurumidza kwedhayi reactive ndeye 4-5, uye kukurumidza kukurumidza kwemachira akadhindwa 4; GB / T5326 Combed polyester-donje yakasanganiswa kudhinda uye dhayi machira akajairwa uye FZ/T14007-1998 donje-polyester yakasanganiswa yakadhindwa uye yekudhaya machira akajairwa zvese zvinonongedza kuti kupenya kwejira rakaparadzirwa / rinoshanda rakadhayi ndiro nhanho 4, uye jira rakadhindwa rakaenzana. 4. Zvakaoma kune reactive dhayi kudhaya machira akadhindwa akareruka kuti asangane nechiyero ichi.

Hukama pakati pedhayi matrix chimiro uye kukurumidza kukurumidza

Kutsanya kwechiedza kwedhayi dzinoshanda kunonyanya kuenderana nematrix chimiro chedhayi. 70-75% yematrix chimiro che reactive dhayi ndeye azo type, uye mamwe ese ari anthraquinone mhando, phthalocyanine mhando uye A mhando. Iyo azo type ine hurombo hwekumhanya kwechiedza, uye iyo anthraquinone mhando, phthalocyanine mhando, uye chipikiri zvine zvirinani kukurumidza kukurumidza. Iyo molecular chimiro cheyero reactive dhayi ndeye azo type. Miviri yemuvara wevabereki ndeye pyrazolone uye naphthalene trisulfonic acid yekumhanyisa kwechiedza. Iwo eblue spectrum reactive dhayi ndeye anthraquinone, phthalocyanine, uye chimiro chemubereki. Kumhanya kwechiedza kwakanakisa, uye chimiro chemolecular ye red spectrum reactive dhayi ndeye azo type.

Kumhanya kwechiedza kunowanzo kuderera, kunyanya kune mavara akareruka.

Hukama huri pakati pekudhaya density uye light fastness
Iko kukurumidza kukurumidza kwemasampuli akadhayiwa kuchasiyana nekuchinja kwekudhayiwa. Kune sampuli dzakadhayiwa nedhayi imwechete pane imwechete faibha, kukurumidza kwayo kupenya kunowedzera nekuwedzera kwekudhayiwa kwekuisa, kunyanya nekuti dhayi iri muIkonzereswa nekushandurwa kwehukuru hwekugoverwa kwezvikamu zvakaunganidzwa pafiber.

Iyo yakakura iyo aggregate particles, iyo idiki nzvimbo pachiyero cheyuniti yedhayi inovhenekerwa nemhepo-unyoro, uye kukwirisa kukurumidza kwechiedza.
Kuwedzera kwekuiswa kwedhayi kuchawedzera chikamu cheaggregates akakura pane fiber, uye kukurumidza kukurumidza kuchawedzera zvinoenderana. Kuiswa kwedhayi kwemachira ane mavara akajeka kwakadzikira, uye chikamu chedhayi aggregates pafiber chakaderera. Mazhinji edhayi ari mune imwe molecule mamiriro, ndiko kuti, dhigirii rekuparara kwedhayi pa fiber yakanyanya. Morekuru rimwe nerimwe rine mukana wakafanana wekuratidzwa kuchiedza nemhepo. , Mhedzisiro yekunyorova, kutsanya kwechiedza kunodererawo zvinoenderana.

ISO/105B02-1994 yakajairika mwenje kukurumidza yakakamurwa kuita 1-8 giredhi chiyero chekuongorora, chiyero chenyika yangu chakakamurwa kuva 1-8 giredhi chiyero chekuongorora, AATCC16-1998 kana AATCC20AFU yakajairika mwenje kukurumidza yakakamurwa kuita 1-5 giredhi chiyero chekuongorora. .

Matanho ekuvandudza kutsanya kwechiedza

1. Kusarudzwa kwedhayi kunobata micheka ine chiedza-mavara
Chinhu chinonyanya kukosha mukutsanya kwechiedza ndiro dhayi pachayo, saka kusarudzwa kwedhayi ndiyo inonyanya kukosha.
Paunenge uchisarudza madhayi ekuenderana nemavara, ita shuwa kuti mwenje wekukurumidza kukurumidza kwechimwe nechimwe chikamu dhayi yakasarudzwa yakaenzana, chero chimwe chezvikamu, kunyanya chikamu chine hushoma, chisingakwanisi kusvika pakumhanya kwechiedza cheruvara. dhayi zvinhu Zvinodiwa zvekupedzisira zvakadhayiwa hazvizosangana nechiedza chekukurumidza mwero.

2. Zvimwe zviyero
Mhedzisiro yedhayi dzinoyangarara.
Kudhayira uye sipo hakuna kunyatso, uye dhayi dzisina kugadzirwa uye hydrolyzed dhayi dzakasara pamucheka zvichakanganisawo kukurumidza kwechiedza chechinhu chakadhayiwa, uye kukurumidza kwavo kwechiedza kwakadzikira zvakanyanya kupfuura kweiyo yakagadziriswa reactive dhayi.
Kunyanya sipo inoitwa, zviri nani kukurumidza kwechiedza.

Simba rekugadzirisa agent uye softener.
Cationic low-molecular-weight kana polyamine-condensed resin type fixing agent uye cationic softener inoshandiswa mukupedzisa machira, izvo zvinoderedza kukurumidza kwechiedza chezvigadzirwa zvakadhayiwa.
Naizvozvo, kana uchisarudza zvinogadzirisa uye zvinyoro-nyoro, kutarisisa kunofanirwa kubhadharwa kune yavo pesvedzero pakutsanya kwechiedza chezvigadzirwa zvakadhayiwa.

Kupesvedzera kwe UV absorbers.
Ultraviolet absorbers inowanzoshandiswa mumucheka wakajeka-ruvara rwemavara kuti uvandudze kukurumidza kwechiedza, asi dzinofanira kushandiswa muhuwandu huzhinji kuti huve nehumwe hunoita, izvo hazvisi kungowedzera mutengo, asiwo zvinokonzera yellowing uye kukuvadza kwakasimba kwejira, saka. zviri nani kusashandisa nzira iyi.
