Abstract: The invention contemplates flexible sheet material having static-dissipative properties and adaptable to wrapping or otherwise containing electronic components or the like which are to be protected against damaging exposure to an electrostatic charge. The sheet material is basically of relatively high surface resistance and is static-dissipative by reason of printed application of a matrix design, using electrically conductive ink, such that at least first and second intersecting sets of spaced plural conductive paths are established at the printed surface. The material is non-sparking by reason of the printed conductive ink being disposed between layers of relatively high surface resistance.

Abstract: The invention contemplates a washable dust-collecting multi-layer electrically conductive web or mat for safely and quickly discharging personnel-accumulated static electricity. An upper continuous polymeric layer of relatively low conductivity, in the order of 10.sup.8 ohms per square and containing a tackifying resin thoroughly dispersed therein, is bonded to an underlying continuous polymeric layer of much greater conductivity, in the order of 10.sup.2 ohms per square, and provision is made for electrically grounding the underlying layer, illustratively by casting to the intermediate layer a continuous bottom layer of expanded polymeric material of relatively low conductivity.

Abstract: The invention contemplates a multi-layer electrically conductive web for safely and quickly discharging personnel-accumulated static electricity, and suitable as an upholstery material. The web comprises an upper continuous polymeric layer of relatively low conductivity, in the order of 10.sup.8 ohms per square, bonded to an underlying continuous polymeric layer of much greater conductivity, in the order of 10.sup.2 ohms per square, and provision is made for electrically grounding the underlying layer, illustratively by casting to the intermediate layer a continuous bottom layer of expanded polymeric material of relatively low conductivity. In the preferred embodiment, a fabric base is laminated to the bottom layer of the web.

Abstract: The invention contemplates a flocked fabric and method wherein flock is adhered by a heat-cured flock adhesive to a substrate fabric and wherein a heat-sublimable dye is contained as a component of the adhesive and/or as preprint of the substrate fabric, the adhesive having a curing time and temperature at which such dye substantially sublimes. Various examples are given to achieve different selectively available color patterns and contrasts, as well as different selectively available surface textures in the dyed product.

Abstract: The invention contemplates expanded-plastic coated fabric wherein the exposed surface of the expanded plastic is characterized by a random distribution of torn cellular pockets and by a random distribution of projecting free ends of flock elements which are rooted to the plastic at their other ends. Various methods of making the fabric are described, with different "hand" or "feel" depending upon the method and upon the materials and their dimensions.
