摘要
本篇从变形加工工艺D／Y比、牵伸倍数、变形热箱温度、超喂率、不同摩擦盘组合及设备状况等诸方面对DTY加工中“僵丝”问题进行了分析，并提出了相应控制措施。
The factors such as D/Y ratio, DR, textured hot box temperature, overfeed ratio,friction twist disc and equipment status, which cause ossified filament on DTY process are analyzed, and the corresponding control methods are proposed.
