acid dye(s)
Molecular formula :
MW :
CAS :

nature : in aqueous dissociation anion generation pigment, to be neutral in acidic bath with the dye for staining. Molecular structure generally contain acid group (-SO3H) or carboxyl (- COOH), hydroxyl (-OH) group soluble. Used mainly protein fiber (such as wool and silk) and polyamide fiber dyeing. Divided into four series : (1) General series, formerly known as acid dyes, acid required in the bath with stained protein fiber; (2) P-Series, formerly known as acid dye, generally acidic to neutral with bath with protein and fiber polyamide fibers; (3) EM Series , formerly known as acid complex dyes, need strong acidic bath with stained protein fiber; (4) NM series, formerly known as dye neutral, generally neutral with bath with protein fibers, aramid fibers and other Villeneuve.
