摘　　要：研究了氨基硅油TSF4708在棉平针织物和毛圈织物上的吸附和解吸动力学及其分布,并将其动力学数据和分布数据与季铵化的增强剂Magnasoft SilQ进行了对比。TSF4708的吸附与质量浓度有关。在最初200 s内,有80%的TSF4708吸附在棉平针织物和毛圈织物上。EDX映射和共聚焦拉曼光谱显示在纤维表面及纤维内部有2μm厚的高质量浓度元素硅层。阴离子洗涤剂存在下的吸附试验发现,相同条件下,TSF4708比Magnasoft SilQ解吸的量更多。The adsorption and desorption kinetics of aminosilicone TSF4708 and its distribution were investigated on knitwear and terry cotton. The kinetic data as well as the distribution data were compared with those for the quaternized textile enhancer Magnasoft SilQ. The adsorption of TSF4708 is a concentration dependent,kinetically controlled fast process. Within the first 200 s,80% of the total amount of TSF4708 adsorbs on knitwear and terry cotton. EDX mapping and confocal Raman spectroscopy highlighted that high elemental silicon concentrations are found in a 2 μm thick layer on the fiber surface as well as in the fiber lumen. The desorption experiments in the presence of anionic detergents showed that under identical conditions,significantly more TSF4708 than Magnasoft SilQ is desorbed.
