摘要:
A process for producing a synthetic fiber composition with reclaimed post consumer carpet yam, wherein face yam is shaved from post consumer carpet using a shaving device to provide shaved face yam, the shaved face yam is reduced in size, contaminants are removed using mechanical screeners, the shave face yam is melt filtered, and then fiber spun.

In a method of producing poly(trimethylene terephthalate) yarn from PTT chip which has been extruded through a spinneret into filaments and coated, the coated filaments are passed between an unheated feed roll and a tension roll to tension them without causing permanent stretching, and then are passed from the tension roll to a heated draw roll to draw the filaments in a single draw step to a draw ratio of 1.25 to 4.0 and to heat them to a temperature between their glass transition temperature and their crystallization temperature.
