A process for the colouration of a substrate of aromatic polyester fibre, alone or blended with other fibres, and textile materials fabricated therefrom, which comprises applying to the substrate a disperse dyestuff and at least one organic liquid having a high dielectric loss factor, a minimum boiling point of at least 120°C and a maximum boiling point belowthe melting point of aromatic polyester or other fibres, the substrate then being exposed to a radiofrequency or microwave field, thereby to heat the organic liquid and to fix the dyestuff on the substrate.
一种用于芳香族聚酯纤维(单独或与其他纤维混合)基材以及由其制成的纺织品的着色工艺,包括将
分散染料和至少一种具有高介电损耗因子、最低沸点至少为 120°C、最高沸点低于芳香族聚酯纤维或其他纤维熔点的有机液体涂抹在基材上,然后将基材暴露在射频或微波场中,从而加热有机液体并将
染料固定在基材上。
