Abstract
A twisted spun fibre yarn with interlaced plies, in which the fibres have a spiral structure having open zones and closed zones, the cohesion factor of the spun fibre yarn being less than 100 and preferably between 20 and 80, the torsion factor of the spun yarn having a value of between 25 and 40% of the torsion factor normally used in the conventional processes for a spun yarn of the same count. A method and apparatus is also described for its manufacture this involving the use of a pneumatic interlacing means and which may be used either continuously or discontinuously.
