  • Patent number: 10080995
    Abstract: A membrane support material is support material for adhering a membrane to a membrane attachment surface. A plurality of non-woven fiber sheets, which are three-dimensional fiber aggregates, are layered together and thermal and pressure processed to bond fibers of the non-woven fiber sheets and form a single sheet of support material. Each layer of non-woven fiber sheet has a different longitudinal-to-lateral tensile strength ratio (k), which is the ratio (f2/f1) of the tensile strength in the lengthwise direction (f2) to the tensile strength in the width direction (f1), and in the thermal and pressure processed state, the support material membrane attachment surface has curvature in the lateral (width) direction with an outward protruding (convex) center region.

  • Patent number: 9057158
    Abstract: A method of making a wiper/towel product includes compactively dewatering a nascent web having cellulosic microfibers and an apparently random distribution of fibers. The dewatered web is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a creping belt. The belt-creping step occurs under pressure in a belt creping nip. The web is dried to form a dried web having a plurality of fiber-enriched hollow domed regions protruding from an upper side of the web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge thereof. The web also has connecting regions of a relatively lower local basis weight forming a network interconnecting the hollow domed regions, and transition areas provided with upwardly and inwardly inflected consolidated fibrous regions that transition from the connecting regions into the sidewalls of the hollow domed regions.

    Abstract: A fibrous insulation has insulation fibers (104) with a fungicide in a dispersed additive affixed to the fibers (104), and a method of making a fibrous insulation by dispersing a fungicide and a dispersed additive on the fibers (104) followed by affixing the dispersed additive on the fibers (104). The method produces thermal, acoustic, duct liner or board insulation either as loose fill insulation or as an insulation mat.

  • Publication number: 20100059190
    Abstract: A method of manufacturing a multilayer fibrous product. The product comprises at least two overlapping layers, each of which has a different fibre composition, and in the production of the product, chemical short stock is used at least partly. In the method, short stock is brought to a screening stage where fines, which pass a screen having an average hole size of 0.2-1.5 mm, are separated from it, in order to prepare at least two fibre fractions having different fibre compositions, and the fractions generated are recovered and included in different layers of the same fibrous product. With the invention, it is possible to screen an initial material and form a product which has better properties than a corresponding product, the initial material pulp of which has only been refined.

  • Patent number: 7563344
    Abstract: Wet-pressed creped tissue sheets exhibit continuous undulating valleys separated by continuous mono-planar macro-ridges running in the machine direction of the sheet, the macro-ridges being of a lower fiber density relative to the fiber density of the undulating valleys. The tissue structure can be created by pressing a densified tissue web against the surface of a Yankee dryer while the web is supported by a texturizing (molding) fabric having a web-supporting surface having highly topographic continuous or substantially continuous ridges and valleys and thereafter creping the web.
