RESEARCH AND DEVELOPMENT OF HIGH TENACITY FIBERS: POLYOLEFINS.

Abstract

Improved spinning speeds up to 900 ft/min were reached. A larger diameter (.040 inch) spinneret, discounting presumably some of the melt fracture limitations experienced with the smaller diameter spinnerets, permitted higher thermal jacket temperatures to be used and as a result the higher spinning speeds. The evaluation of the low thermal hazard extrusion head remains incomplete and the desired increase in I. V. was not obtained. (Author)
