use | is mainly used for dyeing wool top, wool and blanket, and can also be used for dyeing silk and nylon. post-media method should be adopted. Wool fabrics pretreated with chromium acetate can be directly printed with this product. The product can also be used for dyeing leather and as a pigment. This product is a brighter variety of acid mordant dyes, with good levelness, but poor light color and light fastness. It is generally used for dyeing medium or above blue or with acid mordant deep yellow GG, pink 3BM, gray BS, etc. Color matching. it is mainly used for dyeing wool, wool and other wool fabrics, especially for carpet dyeing |
production method | it is condensed with 2,6-dichlorobenzene, after salting out, filtering, drying and other processing processes, the product is prepared. The appearance of the product is orange-red uniform powder, the color and light standard product is similar (pure blue → red light navy blue), the strength is 100±3 (minutes) of the standard product, the moisture content is ≤ 5%, the impurity content insoluble in water is ≤ 1%, the fineness (content of residue through 80 mesh sieve) is ≤ 5%, and the dyeing fastness on the wool fabric conforms to the standard product (sun, soaping, carbonization, dry friction, etc. is grade 4, water immersion, sweat immersion, etc. are 5 levels, cooking, ironing, etc. are 4-5 levels.).
