Carpet tile which includes a base layer having a top side and a bottom side, wherein preferably pile yarns are provided on the top side of the base layer, and a backing layer fixedly connected to the bottom side of the base layer. The backing layer constitutes a bottom surface of the carpet tile, wherein on the bottom surface of the carpet tile an adhesive is applied, and wherein the adhesive imparts adhesive properties to the bottom surface which are sufficient to allow the bottom surface to be attached to a suitable support surface, as well as to be detached from the same support surface onto which it has been attached previously.

Artificial turf for use with an artificial turf system, which may also include a base layer and a support layer. The artificial turf comprising a backing supporting pile tufts of between ¼″ to 4″ in length, in position on its upper surface. The backing may comprise a porous synthetic foam or backing sheet. A filler of particles shaped to have no sharp edges and of substantially equal size are interspersed over the backing and about the tufts up to at least half thick length. The artificial turf substantially retains its resiliency, porosity and equal density throughout.

A novel carpet tile is provided with a roller applied polyurethane adhesive layer at a rate of less than 45 ounces per square yard, resulting in a lightweight backing with exceptional dimensional stability.

The present invention relates polyester tufted carpet where the tufts are engaged with a primary polyester backing and where a polyester roll coating is applied to the backside of the primary backing to lock the tufts which therefore avoids the use of a latex adhesive. The present invention also relates to the use of a polyester roll coating applied to the backside of a nonwoven polyester carpet.

A method for preparing carpet by using polyurethane to anneal secondary backing to a greige, comprising fibers attached to a primary backing using a roller application system. The greige is conditioned prior to coating and the polyurethane coated greige is contacted with the secondary backing and the laminate is tensioned and supported to maintain the laminate structure substantially through the polyurethane curing process.

A primary backing having a component having a front surface and a rear surface, a second component having a front surface and a rear surface placed adjacent and plane-parallel to the first component, and an optional third component having a front surface and a rear surface placed adjacent and plane-parallel to the second component, wherein the first component comprises a two-dimensional material layer, an extruded sheet, and a non-woven fabric and/or a woven fabric. The second component comprises a three-dimensional structure, wherein the three-dimensional structure is build-up from macroscopic thermoplastic fibers, the fibers cross one another at crossing points and are thermally bonded to one another at their crossing points, and the third component comprises a further two-dimensional material layer, wherein the material layer comprises an extruded sheet, a non-woven fabric, a woven fabric and/or a two-dimensional layer of macroscopic fibers.
