摘　　要：通过对阳离子可染聚酯(CDP)熔体性质的分析,探讨了直纺阳离子可染涤纶短纤维的生产工艺条件。结果表明:泵供量与卷绕速度的匹配、冷却成形条件、水浴与热定形温度和后拉伸倍数等因素直接影响阳离子可染涤纶短纤维的质量。By analysis of the characteristics of CDP melt, the process conditions of direct spinning CDP staple fibre were discussed. The results showed that match of the spin pump＇s throughput and the take-up speed, condition of cooling and fiber forming, stretching and thermosetting temperature and after draw ratio would effect the quality of CDP staple fibre.
