Effect of stretching conditions on the properties of polyester textile yarns
- 16 Downloads
By varying the temperature of the heating roll and, correspondingly, the magnitude of the natural stretch ratio, one can obtain a required level of change in shrinkage in a definite sequence; and by periodicity of removal of the yarn being stretched from the heater, one may obtain lengthwise variation in shrinkage of polyester textile yarn.
