Abstract

1,192,397. Drying filamentary material in electric fields. FARBWERKE HOECHST A.G. 7 Aug., 1967 [10 Aug., 1966], No. 36095/67. Heading F4G. A continuous process for heating, drying and/or heat setting a tow of filaments consisting of or containing a synthetic polymer comprises passing the tow in an unravelled state after leaving a crimping chamber through a high frequency electric field having a strength of at least 0.2 kilovolt/centimetre and a frequency of at least 2 megacycles/second.
