    Abstract: The invention provides a process for making a mat particularly a washable dust control mat, having a fabric layer (2) and a rubber backing layer (4) with a border (6) extending beyond the fabric layer (2) using a press which heat-cures the rubber and adheres it to the fabric and employs an inflatable bag (24) to apply pressure by pressing the layers against a heated platen (21), wherein a frame (14) defining the extent of the border (6) is located between the bag and the platen, and wherein the bag applies pressure to the assembled layers including the border portion of the backing layer. The frame (14) can act as a dam for preventing outward movement of the rubber and provide an integral thickened border; in some cases it also provides a guillotine for trimming the rubber during pressing.

    Abstract: An improved cushioned carpet fabric is provided. The cushioned carpet comprises a primary carpet (112) having a plurality of pile-forming yarns (120, 134) projecting outwardly from one side. A layer of reinforcement material (158) is bonded to the side opposite the pile-forming yarns. The reinforcement layer (158) is adjacent to, and embedded in, a cushion layer (178) of a polymer such as a polyurethane. There is preferably no additional adhesive between the cushion layer (178) and the layer of reinforcement material (158) since the primary carpet fabric is mated in-situ to the polyurethane-forming composition without preheating the polyurethane-forming composition. An apparatus and process for forming the cushioned carpet fabric of the present invention are also provided.

    Abstract: This invention relates to a carpet backing latex composition comprising an emulsified polymer, non-cellulosic fibers or a mixture of non-cellulosic fibers and cellulosic fibers, and an effective amount of at least one dispersant for the fibers. Within the scope of the invention is a process for making a carpet backing latex composition comprising adding a dispersant to a carpet backing latex and then adding non-cellulosic fibers or a mixture of non-cellulosic fibers and cellulosic fibers to the latex with slow agitation. Carpet produced with this fiber-containing latex composition is characterized by improved physical properties such as tuft bind.
