<p>A method for the manufacture of a hybrid yarn (26) which uses a stretch-breaking process to blend two or more different types of fibre, one of which is a reinforcing fibre. The fibre tows (2, 14), for example a tow of carbone filaments and a tow of thermoplastic filaments, are fed together into the stretch-breaking zone (at 22), broken by stretching between two pairs of nip rollers (12a, 12b: 20a, 20b), drafted and then processed into a yarn (26). Thus well-blended hybrid yarns are produced which can be of a variety of deniers, including low deniers. The yarns can be used in the formation of composite products.</p> |
