Abstract
1393801 Conjugate fibres MONSANTO CO 24 March 1972 [1 April 1971] 13940/72 Heading B5B A helically crimped side-by-side type conjugate filament comprises, as one component, an acid-dyeable hard polymer other than a polyamide, and as the other, a polyurethane resistant to acid dyes. Preferably the hard polymer is a fibre-forming polyester, and the polyurethane is aged by storing at less than 50‹ C. for at least four days before spinning, especially at least five days. Such a filament, which may have an average modulus of less than 3À9, may be made by (a) preparing a melt-spinnable fibre-forming polyurethane by reacting together, (1) a polymeric glycol having a molecular weight between 800 and 3000, (2) between 4À6 and 8À8 mols. of a diisocyanate per mol. of said polymeric glycol wherein the diisocyanate, if reacted with water, yields a reaction product having a pH of at least 8, and (3) sufficient low molecular weight glycol having a molecular weight less than 500 to provide an NCO/OH ratio between 1À01 and 1À04; (b) storing the polymer at less than 50‹ C. for at least four days, preferably for at least five days; and (c) melt-spinning the polyurethane conjugately side-by-side with a melt-spinnable hard polymer other than a polyamide.
