ABSTRACT:
A method for the production of textile sheets with specific surface effects, and the textile sheet as a product, for outer wear, upholstered furniture or car seat covers or decoration, from yarns of yarn strengths typical for carded yarns (for example, ring-spun yarn, OE Yarn, MJS yarn, friction yarn), generally having low hairiness and low wool portion. This is accomplished in that on one or both surfaces of the textile sheet, a wool fleece remnant is present as the original of the wool fiber portions, the portions penetrating the thread system partially through the entire thickness of the sheet, in the stitch direction of a multiple one or two-sided needle device, and projecting in the stitch direction from the surface of the sheet as a nap, together with such fiber material portions, which have their origin in the textile sheets to be finished. By the needling process, there is a fiber displacement from the fleece through the sheet up to the nap, preferably perpendicular to the surface expansion, by 50 to 1200 perforations per 1 cm.sup.2, by felting needles, resulting in a number of known finishing processes for the production of specific nap-like surface effects being replaced and functional possibilities for yarns with lower hairiness being created.
