A textile sling (10) of the present invention includes a fabric webbing body (1) and reinforced side or sides (2) engaged with the webbing body. The reinforced side or sides are woven to selvedges of the own webbing body from anti abrasion yarns, thus a high protection is obtained to the selvedges of the sling from wearing down. On a surface and around yarns of the sling forms an antiabrasive layer (3) made from polyurethane dispersion with a catalyst solution of modified aliphatic polyisocyanate. A method of manufacturing the textile sling is also disclosed. The final sling product presents greater cut and abrasion resistance.

The invention relates to polyurethane foam forming compositions which produce hydrophilicized polyurethane foams, in particular foams which are suitable as wound dressing foams. These compositions comprise (I) a polyurethane dispersion and (II) specific additives including one or more alkylpolyglycoside. The process of producing these foams comprises frothing and drying these polyurethane foam forming compositions.
