METHOD FOR DETERMINING LEVEL OF BULK AND CONTROL THEREOF

摘要

TITLE Method for Determining Level of Bulk and Control Thereof An apparatus that includes speed, temperature, tension, position and pressure sensors on a BCF yarn spinning machine in connection with a digital computer incorporates models in the computer which predict yarn bulk and dyeability properties at a function of sensor inputs: hot roll temperature, bulking set temperatures, ladder guide tension, relative viscosity, draw zone tension, Hall-effect Watt-meter measuring the power consumption of the spinning pump, finish roll speed, takeup roll speed, wind up speed and wind up tension.
