1. Acid dyes
Acid dyes are a type of water-soluble dyes with structural acidic groups that dye in acidic media. Most acid dyes contain sodium sulfonate, which is soluble in water and produces bright colors with a complete color spectrum. Acid dyes have a complete color spectrum and bright colors, and their light fastness and wet processing fastness vary greatly depending on the type of dye. Compared with direct dyes, acid dyes have simple structures and lack long conjugated double bonds and isohedral structures. Therefore, they lack directness to cellulose fibers and cannot be used for dyeing cellulose fibers. Different types of acid dyes have different dyeing properties due to their different molecular structures, and the dyeing methods used are different.
Foydalanish: Asosan ishlatiladigan uchun bo'yash jun, ipak va nylon, as well as charm, qog'oz, va hokazo. Odatda, no coloring force is exerted on sellyulozik tolalar.
2. Basic bo'yoqlar
Asosiy bo'yoqlar shuningdek tuzga asoslangan bo'yoqlar deb ataladi. Bo'yoqlar kationik bo'yoqlarni ishlab chiqaradigan ajratish mumkin suvli eritmalar va ular c bo'yoqlar. It belgisi bilan yorqin rang, kuchli floresans (asosan gul, sariq, to'q sariq, to'q sariq, va boshqalar)) % 2c kuchli tindirish quvvati, kichik miqdor bo'yoq, va boy rang. U kambag'al rang tezlikka ega tezlik va yorug'lik tezligi, lekin u akril tola (poliol tolasi). Asosiy bo'yoqlar do rang tsellyuloza tolalar mavjud.
Foydalanish: Due to the poor color fastness and color fastness of fibers bo'yalgan bilan alkan bo'yoqlar, u kamdan-kam ishlatiladi bo'yash matolari uchun. U asosan ishlatiladi 1 rang va to'qimachilik stanoklar va qog'oz.
