Abstract
A pile carpet after tufting or the like is usually provided on the back with a latex precoat for stabilization and then provided with a foam back or an additional jute fabric. This environmentally hazardous method and the problem of recycling the foam back as well as the latex layer can be avoided If a nonwoven is applied instead to the tufted back of the carpet by water needling. This is possible with water needling in that the solidification of the pile fibers in or on the primary carrier takes place but no nonwoven fibers reach the visible side of the carpet. The back layer to be needled can also be made thicker and mote voluminous. Instead of a carpet, any other pile goods can also be stabilized in this fashion.
Claims4
Device for carrying out a method for the continuous stabilization of web-shaped goods with a visible side whose structure and quality must not be changed and with a back side which is initially still unstable, including providing a web-shaped product comprising pile-forming fibers held loosely in a primary carrier, providing a nonwoven on the back side of the primary carrier of the web-shaped product;
- and fastening the nonwoven by hydrodynamic water needling to the back side of the primary carrier holding the pile fibers, by penetrating fibers of the nonwoven into the pile fibers on the back side of the primary carrier, to stabilize the pile fibers without changing the structure and quality of the visible side, the device comprising a machine that produces the pile of a web of goods and a device downstream for further treatment for the application of a back layer that stabilizes the pile, characterized in that the device comprises an assembly that supplies a nonwoven, a water needling machine and finally a dryer, preferably.
Web form goods, consisting of a pile placed in a primary carrier and a back layer in addition which anchors the pile to the back of the primary carrier, characterized in that the primary carrier that serves to hold the pile fibers preferably consists of a nonwoven, fabric or knit on its back by means of a nonwoven such as carded nonwoven which is connected with the back by water needling, the back ends of the pile fibers held in the primary carrier are stabilized, in other wards a nonwoven is held on the back of the primary carrier to stabilize the pile fibers by water needling.
Web goods, consisting of a pile applied to a primary carrier and a back layer provided in addition on the back of the primary carrier to anchor the pile, characterized in that the back layer preferably consists of a lightweight nonwoven, or a coarsely woven stability area element and possibly a lightweight nonwoven as well and this composite is held by water needling to the back ends of the pile fibers held in the primary carrier and on the primary carrier as well.
