摘要： Dimensionally stable, high-tenacity non-woven webs and process for their manufacture. The non-woven webs of the invention are distinguished by a relative grab-tensile strength of at least 200 p/g/m.sup.2, a breaking extension of not more than 50% and a shrinkage of not more than 1%, as measured at 160.degree.C, and are primarily useful as reinforceing and backing materials in the manufacture of needle-punched and tufted carpets.

摘要： 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.
