    摘要： A yarn component containing at least one filament is prepared by:selecting at least one partially oriented, undrawn synthetic filament having a birefringence of at least 20.times.10.sup.-3 and an elongation at break of 70-200%, andsubjecting the thus-selected filament or filaments to a heat treatment at 100.degree.-180.degree. C. under tension. The resulting yarn component has a degree of elasticity under a load of 5 cN/tex of less than 50%, which causes the yarn to be especially well suited for use in formable sheet structures.
