摘要:
A textile sheet made with improved surface effects and from yarns with typical unfavorable characteristics (firm round yarn cross-section, low hairiness), of the rotor OE (open end), MJS (murate-jet), sirospun or friction yarns, which, as the result of a multiple needle process with the effect of already known felting needles, shows improved properties including a higher volume, a softer touch, is warmer, and has increased tenacity and hairiness than before the finishing process.
摘要:
A method is provided for the determination and elimination of visible defects in textile webs, wherein the web is moved in the longitudinal direction over a defect seeking and registering area, and the surface position of visible defective areas, such as material deficiencies or excesses with regard to fiber components of the web are located in their surface dimension by known means during the movement of the web, as compared to the adjacent areas of the web. The defective areas are registered as a deviation from the reference condition, and the web is subsequently stopped with the defect in a position above a needle base into which felting needles are sunk. In the case of material deficiencies, the defective areas are supplied with donor material from a reserve, to control their defect by pushing the donor material into the web and stitching it to the defective area with at least two felting needles at 50 to 500 perforations per cm.sup.2, In the case of material excesses, the fiber components of the excesses are pushed into the web by notches or hooks of at least two felting needles at 50 to 200 perforations per cm.sup.2. Following the last perforation in the defective area, the defective web is freed for further movement at a pace relatively faster than the movement of non-aligned donor material, and is separated from the reserve by tearing or cutting.

摘要:
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.
摘要:
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.
