＞ Kutsanangurwa kweDirect Dyes

Direct Scarlet 4BE madhayi anogona kupiswa uye kubikwa mune kwaakarerekera uye asina kusimba bond chikamu chepakati pasina rubatsiro rwema mordants.Dhayi dzakananga dzinoumbwa ne hydrogen bonding van der Waals force pakati pedhayi dzakananga nedonje fibers.Madhayi akananga ane mapoka anonyungudika nemvura akadai semapoka e-sulfonic acid (-SO3H) kana mapoka e-carboxyl (-COOH) uye zvimiro zvawo zvemamorekuru zvakarongwa mu mutsara chimiro.Zvimiro zvemhete zvinonhuhwirira zviri mundege imwechete, saka madhayi akananga ane hukama hukuru hwemaselulosi fiber.Inogona kudhayiwa yakananga mune isina kwayakarerekera uye inogona kudhayiwa chero dhayi iri kunyungudika mumvura.Kune dhayi dzakananga nekusagadzikana kwakashata, soda ash inogona kuwedzerwa kubatsira kunyungudika.Madhayi akananga haapikisane nemvura yakaoma.Mazhinji acho anogona kusanganisa necalcium uye magnesium ion kuti igadzire mvura isinganyungudika, zvichikonzera mavara pamachira akadhayiwa.Nokudaro, dhayi dzakananga dzinofanira kunyungudutswa mumvura yakapfava.Kana kuoma kwemvura yedhayi inoshandiswa mukugadzirwa kwakakwirira, soda ash kana sodium hexametaphosphate inogona kuwedzerwa, iyo isingangobatsiri kunyungudutsa dhayi asiwo kupfavisa mvura.
