  • Patent number: 4285216
    Abstract: A fabric having a novel warp lift-off-resistant construction is made on a stitch-through type machine equipped with a single knitting thread guide bar and comprises a flexible substrate such as a layer of textile yarn filling elements, a plurality of warp elements laid on the substrate in the longitudinal or warpwise direction, and knitting thread forming a multiplicity of warpwise stitches in a warp lift-off-resistant configuration. The knitting thread warp lift-off-resistant configuration comprises, in one embodiment, a combination of at least one half-tricot stitch course and one or more consecutive chain stitch courses on a given knitting thread wale to bind together into an integrated structure the substrate and warp elements, to secure the substrate and warp elements against relative displacement, and to stabilize the fabric against running or lifting off of the warp elements from the fabric surface.

  • Patent number: 4277527
    Abstract: A laminated structure for use in wall construction is disclosed which comprises a rigid support and an integrally self-lined textile material having a front surface and a rear surface and adhesively bonded on its rear surface to the rigid support. The textile material comprises, in one embodiment, (i) a nonwoven spun fibrous batting constituting the rear surface of the textile material and capable of being stitched-through without substantial loss of strength by knitting thread; (ii) a layer of filling disposed upon the batting; (iii) one or more warp elements disposed upon the filling so as to constitute the front surface of the textile material; and (iv) a single system of knitting thread wales, each wale comprising a multiplicity of warpwise looped stitch courses which engage and hold together the batting, filling and warp elements into an integrated unitary textile structure.

  • Patent number: 4192160
    Abstract: A fabric is produced in a stitch-through type machine such as a Malimo maching using the apparatus and method of the invention which has at least two warp yarn design elements laid on a flexible substrate (e.g., a layer of textile filling elements) along rectilinear or non-rectilinear paths and on which a plurality of adjacent design elements are twisted (e.g., symmetrically at 180.degree. per twist) in an aesthetically pleasing configuration at spaced intervals along the warp direction. The design elements are bound to the substrate by knitting thread which forms a multiplicity of warpwise loop chains (e.g., a half-tricot stitch) to secure the substrate and design elements against relative displacement and to form thereby an integrated fabric structure.
