Abstract: ABSTRACT   Stable aqueous dispersions of crosslinked polyurethane particles are disclosed.  Preferably the aqueous dispersions coalesce, upon drying, to form continuous films.  The aqueous dispersions of crosslinked polyurethane particles are formed by reacting a mixture of polyfunctional hydrogen compounds, one of which has an ionically neutralizable solubilizing group thereon and one of which has a functionality of three or more,  with a diisocyanate to form a non-crosslinked or ungelled prepolymer.  The solubilizing group is neutralized and the prepolymer is dispersed in water.          The prepolymer is chain extended with water or an aqueous solution of a water soluble diamine to form an isocyanate free dispersion of crosslinked polyurethane polymer.

Abstract: ABSTRACT OF THE DISCLOSURE     Staple fibres made from crimped, in particular compression crimped, multi-component filaments of the matrix/-segment type, the cross-section of which comprises, in addition to the matrix, at least 6 peripheral wedge-shaped or lenticular segments, not completely covered by the matrix, are processed into a web, which is then mechanically bonded, preferably by needling.  Subsequently the fabric is subjected to a shrinkage process, by which its density is increased by more than 30%, the multi-component fibres being completely or partly split up into their components.  The difference in shrinkage between the components should be at least 10%.          The liquids used for the shrinkage treatment are in particular organic liquids, such as methylene chloride, as well as other liquids producing a difference in shrinkage of at least 20%.          The fabric is then impregnated with a solution of polyurethane on  the basis of polyglycols, specifically polytetramethylene glycol, diisocyanates and low-molecular glycols as chain lengtheners, the gelling temperature of the solution being higher than the room temperature and higher than the tempera-ture of the coagulation bath used; the polyurethane is coagulated by cooling and/or treatment with a coagulation bath containing a non-solvent for polyurethane; then the fabric is washed, dried and ground on one or both sides.  The suede-like product obtained combines great suppleness with high strength.  It is an excellent material for making garments, such as coats, jackets or skirts, offering high wear comfort as well as high breathability.
