ABSTRACT:
A spunbonded fabric of nylon 6, bonded by binders such as polyacrylates and polyurethanes, in which the filaments are substantially in the .gamma.-modification in the crystalline regions and the average molecular orientation, produced by attenuation, of the nylon 6 filaments is at most 80% of the theoretically possible orientation. It is an object of the invention to produce spunbonded fabrics of improved properties and to do so more economically, e.g. with higher outputs.
