Improving Properties and Processing Performance of Melt-Spun Fibers

Abstract

The properties, yields, and efficiencies achieved in the overall fiber-making process are often governed by the orientation level and by variations in denier and orientation introduced in the extrusion/melt spinning part of that process. Essential to optimization and improved control of these processes is an understanding of the underlying physical phenomena and control of the appropriate variables. This paper builds on 30 years experience and demonstrates what variables need improved control — and why.
