Niki Cyiza Cyuzuye Irangi? Ibyingenzi byingenzi bituma biba byiza kumyenda yohejuru

Irangi risize irangi ryakozwe hifashishijwe uburyo bwo guhuza imiti aho molekile zisize irangi zikora covalent hamwe na fibre polymers, bigatuma ibara rihoraho. Bitandukanye nuburinganire bwurwego rwo hejuru, uku guhuza molekuline bituma amabara adasanzwe kandi akaraba-yihuta. Ikoranabuhanga ryiza cyane kuri fibre ishingiye kuri selile nka pamba na rayon, aho amatsinda ya hydroxyl muri fibre akora hamwe n amarangi yamabara mugihe cya alkaline. Kurenga ubwiza, amarangi adasanzwe yongerera imbaraga ubudodo-guhuza imiti birinda fibre fibre, bikomeza kwifata neza hagati ya 15-20% kuruta ubundi buryo busize irangi. Ibi bituma iba zahabu ya myenda yimyenda ihebuje aho uburebure bwigihe kirekire hue hamwe no kwambara neza ntibishobora kuganirwaho.

Impamvu Yera Yuzuye Irangi Nuburyo bwiza bwo guhitamo imyenda yamabara

Guhuza covalent mumyenda isize irangi itanga amabara atagereranywa, bigera ku gipimo cya ISO 4-5 cyo gukaraba no kwihuta-byingirakamaro kumyambaro, igitambaro, hamwe nimyambarire y'abana bihanganira kumesa buri munsi. Bitandukanye n'irangi ritaziguye rifite fibre gusa, irangi ryikora rihinduka mubice bya molekile, bikarwanya gushira kumashanyarazi, chlorine, cyangwa UV. Igeragezwa ryerekana ipamba irangi irangi igumana 90% + ubukana bwamabara nyuma yo koza inganda 50, irusha bagenzi babo 30%. Ibicuruzwa bigamije kuramba, kuva Eileen Fisher kugeza kuri hoteri nziza ya hoteri, shyira imbere ikoranabuhanga kugirango ubungabunge ibyiza byibicuruzwa mumyaka myinshi ikoreshwa.

Reaction vs Disperse vs Vat Dyeing - Nuwuhe marangi irangi ubereye umushinga wawe wimyenda?

Buri buryo bwo gusiga amarangi bukora ubwoko bwa fibre butandukanye nibikorwa bikenewe. Irangi rifatika ryiganje muri fibre karemano (ipamba, imyenda, rayon) hamwe na molekile ihoraho kandi isobanutse neza. Kurangi amarangi, nubwo bikoresha polyester, bisaba ubushyuhe bwinshi (130 ° C +) kandi ntibibuze inyungu zo guhumeka neza. Irangi rya Vat ritanga urumuri rwiza ariko rurimo kugabanya uburozi bugabanya ibara ryinshi. Kubashushanya bakorana na fibre ishingiye ku bimera, gusiga irangi ni byo byatsinze neza - bihuza umwirondoro w’ibidukikije (ibyuma bito bito birahari) hamwe n’igicucu cyimbitse cyane, bigatuma ombrés ningaruka za heather bitagerwaho nubundi buryo.
