Abstract
1488776 Composite polyester fibres HOECHST AG 12 May 1976 [14 May 1975] 19546/76 Heading B5B The fibres comprise an inner core of a hydrophilic linear polyester and the outer core of a non-hydrophilic linear polyester. Preferably the hydrophilic linear polyester is a block copolymer of from 90-20% by wt. relative to the polyester of polyethylene terephthalate and from 10 to 80% of a polyalkylene glycol. The hydrophilic linear polyester may also contain by incorporation or co-condensation 5-20% by wt. relative to the salt free ester of an alkali metal salt or an alkaline earth metal salt of a sulphonic acid or an acidic phosphoric or phosphonic acid ester.
