Abstract

529,017. Yarns. SOC. ITALIANA PIRELLI. May 19, 1939, No. 15000. Convention date, May 25, 1938. [Class 120 (iii)] A rayon thread of 3000 denier or more for use in the manufacture of tyre covers and belting is made from a single yarn or from a group of a few yarns each of a large number of filaments, twisted together with a high twist and with a relatively high measure of tension applied to the yarn or group of yarns during or after the twisting operation or operations so as to produce a finished thread having high resistance to fatigue and a low elastic extensibility giving a total extensibility at break of not above 18 per cent; in the case of a single yarn thread the twist gives to from 15 to 25 turns per inch and in the case of a thread made from a group of yarns, the individual yarns are given a twist of from 20 - 35 turns per inch and are twisted together with 11 - 14 turns per inch.
