Abstract

1,256,487. Opening tows. TOYO BOSEKI K.K. 24 March, 1970 [29 March, 1969], No. 14326/70. Heading D1F. Substantially non-twisted multifilamentary yarns or tows are separated electrostatically by passing the yarn through a tubular first electrode 5 in contact therewith, and then through a second electrode 6, 8 or 9 without contact, the potential difference between the two electrodes being at least 500v. The second electrode may be frusto-conical (Fig. 2), toroidal (Fig. 3), or a plurality of plates or bars 9. The separated filaments may be gathered in the form of a web, two or more of which may be lapped together.
