  • Publication number: 20240158965
    Abstract: A bonded and entangled non-woven structure made of at least 50% staple fibers by weight of the bonded and entangled non-woven structure, and at least a partial bonding of the fibers of the non-woven structure. The at least partial bonding including thermally activated bonds between a first polyolefin material produced with a catalyst including at least one metallocene catalyst and having a melting point in the range 130-170° C. and a second material having a melting point which is at least 10° C. higher than the melting point of the first material, the weight of the first material in the non-woven structure being at least 3% of the weight of the nonwoven structure.

  • Publication number: 20210230883
    Abstract: A co-foamable vinyl plastisol composition, a gelled or fused co-foamed vinyl layer, a co-foamed vinyl layer, methods of manufacture of the layer and use of the layer in floor coverings such as sheet vinyl, cushioned vinyl flooring, floor tiles, and laminated planks are described. The co-foaming is preferably a sequential foaming of a single layer such as a single coated layer, such as sequentially applied mechanical foaming or frothing followed by chemical foaming. A co-foamable vinyl plastisol composition is mechanically foamed/frothed before it is applied to a substrate. Once on the substrate, the co-foamable layer can be processed further and is chemically foamed in a later process step.

  • Patent number: 9809910
    Abstract: A warp knitted heat resistant separation fabric is provided, having at least two sets of warp yarns. A first set of warp yarns is positioned over the width of the fabric and formed with pillar stitches; and a second set of warp yarns positioned over the width of the fabric shows in its repeat in the fabric an underlap under at least two pillars that are formed by the first set of warp yarns.
