Abstract
Thin walled tubing formed of a melt spinnable synthetic polymer having a flow-through cross-section amounting to 30 to 95% of the total tubular cross-section and a breaking elongation of less than 100% prepared by melt spinning a synthetic polymer so as to form a tube and then drawing off the tube thus formed at a velocity which is greater than 3500 m/min. Preferably the process is carried out under utilization of the phenomena of natural fiber bending whereby the distance between the spinning means and the take-off means can be decreased.
