In twisting a yarn running over a guide surface, the twist inserted into the part in front of the guide is frequently accumulated so as to transmit freely to the part behind the contact zone and cause downstream twist blockage. A new device was set up here for investigating the twist blockage and yarn torque-twist simultaneously. Measurements on the relationship between twist and different parameters were carried out by using a monofilament yarn and a multifilament yarn. The influencing factors being taken into consideration include the wrap angle, yarn tension and input twist.
