    Abstract: A floral sleeve is made from two layers of non-woven thermoplastic fabric such as polypropylene. The layers are joined at the side seams of the sleeve by first pre-sealing the edges and thereafter trimming them. Pre-sealing compresses the fabric to make it denser along a band and applying heat causes the band to retain the compressed and at least partially fused set. Trimming may be done using a hot knife that completes the fusing process of the layers to each other. Alternately, the pre-sealing step may form a satisfactory fusion between the layers and the trimming step need not effect further fusion.

  • Publication number: 20110203226
    Abstract: Provided is a three-ply insulating material which has combined properties to selected gases and vapors, thermal insulation, and humidity control. The device is built as a composite of three layers. The outer layer is made from breathable non woven composite. This layer is adjacent to and bonded to the middle layer, composed of high loft fibrous material with substantial weight to volume ratio, between about 2 to about 20 kg/m3. This middle layer is adjacent to a third layer of breathable non woven composite. The composite layered structure so designed forms an insulation blanket with thermal resistance of about 0.8 m2 ° K/W and moisture vapor transmission rate (MVTR) between 50 and 10000 l/m2/hr.

    Abstract: An absorbing structure has a sequence of layers, including at least first and second outer layers with at least a liquid storage layer disposed therebetween. The layers are disposed on top of one another and form a layered structure. At least the liquid storage layer has a cellulose material, preferably cellulose fibers, and a super absorbing polymer SAP, preferably SAP particles and/or SAP fibers. The liquid storage layer uses at least less binder material than the other liquid storing plies of the absorbing structure. The liquid storing plies are adjacent to the liquid storage layer. Preferably, the liquid storage layer does not have binder material.
