Abstract

Abstract A needled, non-woven pile fabric comprises a non-woven backing fabric and a non-woven face fabric. The face fabric has its face side printed with an ornamental pattern of pigment color. The backing fabric and the face fabric are needled together so that the fibers of the backing fabric penetrate through the face fabric and mingle with the fibers of the face fabric to form a pile on the face side of the face fabric. The ornamental pattern is thereby imparted with a soft three-dimensional appearance. A method is also disclosed for producing the non-woven pile fabric. According to the method, a web of a non-woven backing fabric is placed in face-to face relationship with a web of nonwoven face fabric having a decorative pattern of pigment color printed on its face side, with the printed face side of the face fabric facing away from the backing fabric. The two webs are then needled from the free or uncovered side of the backing fabric in a direction towards the face side of the face fabric so that the fibers of the backing fabric penetrate through the face fabric and mingle with the fibers of the printed face fabric to form a pile layer on the printed face side. The backing fabric and the face fabric may be of a single color or of blended colors.
