Textile material consisting wholly or partially of polyester or polyamide fibres or filaments is padded or printed with aqueous padding liquors or printing pastes which contain at least one dispersion dye. After padding or printing the textile material is brought into contact, directly or after intermediate drying, with methylene chloride vapour. The dye is fixed by causing the methylene chloride vapour to condense on the padded or printed textile material and leaving the thus treated textile material to dwell. The cold fixing process requires a small amount of methylene chloride. Deep, level dyeings are obtained. |
