Abstract

The core composed of long-fibre yarns, preferably obtained by cracking, is raised in twist during the actual spinning operation carried out continuously on a ring-spinning frame without reaching its critical twist coefficient alpha "0, the cover of the said core being made of long fibres or short fibres. The twist coefficient of the core yarn lies between 20 and 85. <IMAGE>
