| Abstract: | Conclusions A mathematical model has been proposed for the process of heat-exchange between yarn and heating chamber which permits one, with reasonable accuracy, to describe the yarn temperature distribution over the length of the heater and beyond its limits. This model affords the possibility of calculating the amount of heat carried off by the yarn from the heating chamber and to estimate heat losses into the environment, and, consequently, to select the most economical heater.By connecting up the dynamics of yarn heating with yarn properties, the mathematical model developed permits one to calculate the optimum temperature profile in a heating chamber. Using this model, one can transfer the optimum conditions for heat-stretching yarns to other temperature-time levels.Translated from Khimicheskie Volokna, No. 2, pp. 54–56, March–April, 1989. |
