More Information
Summary:A composition for treating leather, fur and fibrous material which comprises a water-soluble and/or a water-dispersible polyurethane, and more particularly a composition comprising the following ingredients a), b), c) and d) in the following proportions: -ingredient a);water-soluble and5.0-100% by wt.-water-dispersible polyurethane-ingredient b);salt of divalent to0.0-20% by wt.-tetravalent metal-ingredient c);surfactant0.0-40% by wt.-ingredient d);auxiliary ingredients0.0-40% by wt.- Leather and fur treated with the treating agent of the invention can be washed in water. Even when washed in water, they retain flexibility, have an excellent dimensional stability and are enhanced in water absorption into leather fiber. Further, they are improved in tear strength, tensile strength and hand and become easy to sew by means of a domestic sewing machine. When woven, knit and unwoven fabrics made of natural fibers such as animal hair, wool, silk, cotton and the like or their mixed fabrics with synthetic fibers are treated with the treating agent of the invention, a dimensional stability and shrink resistance after washing can be given to them without affecting their hand.
