Abstract: 1,252,738. Yarns; staple fibres. LINEN INDUSTRY RESEARCH ASSOCIATION. 20 Jan., 1969 [18 Jan., 1968], No. 2760/68. Heading D1F. A method of producing staple fibres from a polymeric film includes the steps of fibrillating the film to form a network and stretch breaking the film as it passes between successive pairs of breaking rollers and is characterised in that the reach between successive pairs of breaking rollers is not less than the "mesh dimension". The "mesh dimension" is defined, in the case of a fibrillated network having longitudinal rows of splits equally spaced across its width, as half the length of the split plus half the length of the distance between successive splits. The staple fibres produced may be converted directly into a yarn. In operation, tapes T of drawn polypropylene are fed to the input nip 14 of a fibrillator 16 via a tension controller 12. The fibrillator comprises a pinned fibrillating roller 20 operating at a faster throughput speed than the tapes T. The pinned roller 20 rakes the tapes as they pass through to form a fibrous network. The fibrillated network is withdrawn by an output nip 26 operating at a greater speed than the input nip 14. A finish may be applied to the network at bath 28, e.g. an anti-static finish, and the network is then passed to the breaking zone which consists of two sets of nip rollers 32, 34. The reach d is chosen to be not less than the mesh dimension. The sliver produced may be passed to a car-coil device 36 or directly to a spinning machine. The stretch breaking process may be followed by carding or gill frame spinning to produce a smooth yarn.
