ABSTRACT:
To make a velour needle felt, an optionally pre-needled staple fiber non-woven web is applied to a revolving brushlike support and is then needled to form a pile on the side which faces the support. To increase the resistance of the velour needle felt to distortion, it is proposed that a layer which has a higher resistance to distortion than the staple fiber non-woven web and consists particularly of a spun-bonded web is applied to the brushlike support before the staple fiber non-woven web is applied thereto and that the pile fibers are pulled in the needling operation through the layer which has the higher resistance to distortion.
