摘　　要：对相同成分、不同粒径的3种远红外粉体悬浮液的分散性能及在皮革上的应用情况进行了研究。用超声波细胞粉碎机来解聚悬浮液中粉体颗粒,并用吸光度来表征其分散效果,结果表明:最大吸收波长与粒径大小无关;同一波长下,粒径越大,其吸光度越大;粒径越大,其最佳分散剂用量越小,而最佳超声解聚条件越强。相同质量浓度的粉体悬浮液处理皮革后,用升温和降温性能表征皮革的保暖性,结果表明:经远红外粉处理的蓝湿革的保暖性能,明显优于未经远红外粉处理的蓝湿革,且粉体越细,处理的蓝湿革的保暖性能越好。Three kinds of far infrared powders suspension, and application of them to leather were studied. Dispersion degree of these powders suspension dispersed with an ultrasonic cell disrupter system was expressed by absorbency. The result showed that the maximum absorbency wavelength（ λm for short）does not rely on the particle size; with the same concentration, the bigger the particle is, the greater the absorbency is at the same wavelength ; the bigger the particle is, the less optimal dosage of dispersant is needed, and the stronger the optimal ultrasonic condition is needed. Warm keeping performance of leather dealt with the suspension, was measured using methods of temperature rising and declining, The result showed that warm keeping performance of leather processed by far - infrared powder aqueous suspension is improved markedly, and in the same conditions, warm keeping performance of leather processed with the smaller size powder particles is the better than that with larger one.
