摘　　要：研究了超声波作用下碱预处理对聚酯超细纤维高温高压染色后表面环状三聚物含量的影响。结果表明 ,在超声波作用下 ,碱预处理能显著降低聚酯超细纤维染色后表面环状三聚物含量 ,无超声波作用 ,纤维表面环状三聚物含量为0 .38% ;超声波作用下纤维表面环状三聚物含量为 0 .0 4 7% ,而且不影响纤维物理性能。The influence of alkali pretreatment under ultrasonic on surface cyclic trimer content of superfine polyester fiber using high temperature high pressure dyeing process has been studied. The results show that: alkali pretreatment under ultrasonic can remarkably decrease the surface cyclic trimer content of superfine polyester fiber. The amount of the reduced surface cyclic trimer content of fiber only by alkali pretreatment without ultrasonic is 0.38%; with ultrasonic is 0.047%. The physical properties of fiber are not affected.
