Abstract

Abstract A process for manufacturing varicolored, ornamentally designed needled non-woven fabrics which comprises applying to a first web of a needled, single-colored or blended non-woven fabric, a second web of non-woven fabric of a different color contrasting from the color of the first fabric, said second web having been glued and dried in accordance with a desired pattern, attaching the two webs to one another by a needling operation in such a manner that the areas free of glue of said second web are passed through by needles whereby filters of said fabric are taken along and will appear at the rear face of the first web of non-woven fabric forming a finished pile thereon, while at the glued areas only a partial connection of the two fabric webs is effected by needling without the fibers being passed through to the rear face of said first web.
