Abstract (en)

[origin: JPS6445882A] PURPOSE: To obtain a uniform printed material having excellent build up property and excellent in fastness by applying a specific resist agent alone or in combination with dye to a textile planar fabric made of natural or synthetic polyamide, heat-treating the fabric and subjecting the fabric to ground dyeing with anionic dye. CONSTITUTION: A resist agent comprising a melamine compound represented by the formula [R1 to R3 are each phenyl, naphthyl or the like; Z is acidic water-soluble group (e.g. sulfo group); (m) is 1-6] alone or a resist paste combined with anionic dye or fluorescent whitening agent is locally applied (printed) to a textile planar fabric (e.g. carpets) made of natural or synthetic polyamide and then, the fabric is subjected to ground dyeing by an absorbing method by using anionic dye to provide a printed material excellent in fastness of light resistance, washing resistance and abrasion resistance. The dyeing method is especially effective in production of carpet and can provide homogeneous carpet having gloss.
