Abstract

A method for the finishing of textile sheets, in which textile sheets for outer wear, upholstered furniture and car seat covers, as well as for decoration, preferably made of yarns having yarn strengths typical for carded yarns and/or worsted yarns (for example, ring yarns, OE-yarns, MJS yarns, friction yarns), are adjusted in a "custom-made" fashion, according to the sheet forming process. Textile sheet is supplied to a needling process alone, or together with the most varied sheets (for example, fleece, woven materials, foam materials, etc) or warps as well. Because of the needling process, by means of which the fibers are displaced from one layer into another with 50 to 1200 stitches per cm.sup.2 by felting needles, preferably CB notched needles, there is a permanent layering which, however, for the production of sheets with naps, can be cut as well.
