A dimensionally stable universal floor covering includes a tufted textile having stitches and a reinforcement layer operatively connected to the stitches to provide dimensional stability for the entire floor covering. The reinforcement layer is made of fibers and adhesive that are formed into a reinforcement layer of laminated fibers that is operatively connected to the stitches and/or the fibers and adhesive are formed into a layer of fibers and adhesive that is contained within the stitches. The fibers and adhesive are mixed and then moved by an applicator toward the stitches. A curved slip path is formed on a curved portion of the applicator to improve the movement of the fibers and adhesive toward the stitches. A removable tip portion on the end of the curved portion of the applicator improves the penetration of the adhesive and provides compression of the fibers towards the ends of the stitches. A releasable adhesive cover system is provided to cover the layer of fibers for providing additional strength and stability and for providing a releasable attachment of the universal floor covering to a supporting surface.

A dimensionally stable floor covering comprises a tufted textile substrate and a reinforcement layer attached to the textile substrate. The reinforcement layer includes an adhesive backing compound and reinforcement fibers surrounded by the adhesive backing. The fibers may form a continuous layer on the back side of the floor covering or may be dispersed within the adhesive backing compound. The adhesive backing compound may be hot water-soluble to facilitate recycling of the floor covering. The floor covering may optionally include additional backing layers (including cushions) and may be used as a broadloom carpet, a carpet tile, or other modular floor covering products. Methods of manufacturing, installing, and recycling the present floor coverings are also provided.

A highly homogeneous starch-based glue composition is obtained by enzymatic modification of the starch with a branching enzyme which is supplied in an enzymatically modified starch with high long-term stability. The starch has a viscosity stability index SI of less than or equal to 1.3, calculated by the quotient of viscosity after 14 days and by viscosity after 2 hours after preparation of the starch. The starch is suitable for liquid storage, which is stable in the long-term, of a ready-to-use paste with a high bonding strength.

The present invention provides a novel pressure-sensitive adhesive composition including a glucan derivative. The pressure-sensitive adhesive composition of the present invention includes a glucan derivative G having a glucoside bond A, and a glucoside bond B having a different bonding form from the glucoside bond A. The glucoside bond A is, for example, a 1,6-glucoside bond. A pressure-sensitive adhesive sheet 1 of the present invention is formed from the pressure-sensitive adhesive composition. A laminate 10 of the present invention includes the pressure-sensitive adhesive sheet 1 and a substrate sheet 2.

The present invention provides a pressure-sensitive adhesive composition suitable for forming a pressure-sensitive adhesive sheet having a smooth surface. The pressure-sensitive adhesive composition of the present invention includes a -1,3-glucan derivative G. The pressure-sensitive adhesive composition has a tan of 0.7 or more at 200 C. as determined by the following test. Test: a disc-shaped evaluation sample is produced from a pressure-sensitive adhesive composition. The evaluation sample is subjected to a dynamic viscoelasticity measurement to determine a tan thereof at 200 C.
