Abstract

1408094 Polyester mixtures HOECHST AG 17 April 1973 [22 April 1972] 18476/73 Heading C3R [Also in Division B5] A composite filament comprises Polyethylene- 1,2-diphenoxyethane-4,4<SP>1</SP>-dicarboxylate as first component and a polyalkylene terephthalate having 3 or 4 carbon atoms in the alkylene group (suitably polytrimethylene terephthalate or polytetramethylene terephthalate) as the other component, the two components being arranged eccentrically over the filament crosssection. The filaments may be of the side-byside or eccentric sheath-core type. In a modification, up to 25 mole per cent of the dicarboxylic acid units in the polyethylene-1,2-diphenoxy - ethane - 4,4<SP>1 </SP>- dicarboxylate and/or up to 25 mole per cent of the terephthalic acid units in the polyalkylene terephthalate may be replaced by units from one or more other dicarboxylic acids. Further, up to 25 mole per cent of the alkylene glycol units in the polyalkylene terephthalate or modified polyalkylene terephthalate and/or up to 25 mole per cent of the ethylene glycol units in the polyethylene- 1,2 - diphenoxyethane - 4,4<SP>1 </SP>- dicarboxylate or modified polyethylene - 1,2 - diphenoxyethano- 4,4<SP>1</SP>-dicarboxylate may be replaced by units from one or more other glycols.
