Abstract
A method of estimating yarn temperature comprises, measuring the temperature of a guide pin in contact with the yarn; measuring the tension of the yarn with a tensiometer; and estimating yarn temperature using the correlation: EQU Tyarn=k1+k2.times.Tpin-k3.times.(F-k4) wherein Tyarn is the estimated temperature of the yarn: PA1 k1, k2, k3 and k4 are empirically determined constants; Tpin is the temperature of the guide pin; and F is yarn tension.
