Abstract
In the instant invention, drawn yarns, with the following properties, are obtained: tenacity of at least 8.5 gpd; initial modulus of at least 150 gpd/100%; and shrinkage of less than 6%. Alternatively, the yarn may be characterized as: tenacity of greater than 10 gpd; initial modulus of greater than 120 gpd/100%; and shrinkage of less than 6%. These yarns are made by a process directed mainly toward affecting the yarn properties as they are spun.
