Novel spun polyethylene terephthalate strands of improved percent elongation at break and initial modulus are obtained by (1) passing the strand under tension through a jet gas stream such as steam at a rate and gas temperature that effects fusion to the degree that the pulse propagation of the treated strand over a strand distance of 60 centimeters while under 20 grams tension is reduced to less than 300 microseconds or (2) passing the spun strand under tension around a roll heated to a temperature of about 175.degree. to 195.degree. C. at a rate of about 300 to 500 feet per minute.
