Abstract

1497664 Polyester yarns SNIA VISCOSA SOC NAZIONALE INDUSTRIA APPLI CAZIONI VISCOSA SpA 24 Dec 1974 [27 Dec 1973] 55772/74 Heading B5B A multi filamentary polyester yarn is obtained by collecting the yarn at a linear speed greater than 4700 m/min, the yarn showing a crystallinity of 30-60% and a residual drawing capacity if not greater than 1À2. The yarn may be fake twisted without further drawing of the yarn.
