Technological aspects of orientational strengthening of poly(ethylene terephthalate). Modern schemes for production of high-strength polyester fibres

摘要

Theoretical and technological aspects of orientational strengthening of polyester fibres are examined. High strength of polyester fibres is attained by the combination of the high molecular weight of poly(ethylene terephthalate) with stage-wise (in several stages) drawing. Current schemes for production of high-strength polyester fibres are reported.
