发明名称 Dyeing or printing synthetic fibres and blends with cellulose - using development dyes with subsequent heating
摘要 <p>Dyeing or printing of synthetic fibres and their blends with cellulose fibres, using mixts. contg. (a) a stabilised diazotised aromatic amine; (b) a coupling component composed of an arylide of acetoacetic acid, 2-hydroxy 3-naphthoic acid or 2-hydroxy carbazole 3-carboxylic acid, or of a 1-aryl pyrazolone-(5); (c) a base in equiv. amount to (b); (d) a thickener and opt. (e) an acid donor. The dye is developed and fixed by treatment with superheated steam, contact heat, hot air or a combination of these. In absence of (e), development is by treatment with and acid material. Both synthetic and cellulose fibres are simultaneously dyed in even, intense shades by use of the same dye.</p>
