ABSTRACT:
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 as a function of sensor inputs: hot roll temperature, bulking jet temperature, 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.
