摘　　要：使用纤维素纤维改性剂聚环氧氯丙烷胺化物(PECH-amine)对涤棉中的棉进行改性,讨论了改性剂用量对涤棉织物接枝率、透湿性及吸湿性的影响,比较了改性前后一浴法染色的K/S值.试验结果表明,涤棉织物经改性后产生接枝现象,透湿性下降,渗透性增大;改性后涤棉织物一浴法染色K/S值较改性前提高了一倍以上.The cotton constituent in polyester/cotton blends was modified with the modifier polyepichloro- hyrin-dimethylamine （PECH-amine）. The effect of modifier concentration on grafting yield, moisture permeability and hygroscopicity of polyester/cotton fabric was discussed. The K/S values of one bath dyed polyester/cotton fabrics before and after modification were compared. The results showed that the polyester/cotton fabric was grafted after modification, and the moisture permeability decreased and permeability increased. Compared with the unmodified polyester/cotton fabric, the K/S value of the modified fabric dyed in one bath increased over 100 %.
