    Abstract: An apparatus and method for creation of moiré fabric. This can be achieved by placing a first piece of fabric against a support member and directing at least one stream of fluid at the surface of said first piece of fabric to provide lateral yarn displacement. Then delivering said stream at a peak dynamic pressure in excess of about 300 p.s.i.g. and less than 4,000 p.s.i.g. and selectively interrupting and re-establishing contact between said stream and said surface in accordance with pattern information in order to pattern said first piece of fabric. This is followed by combining said patterned first piece of fabric with an unpatterned second piece of fabric in overlapping relationship and applying pressure by means of calender rolls having smooth surfaces to said combination of said first piece of patterned fabric and said second piece of unpatterned fabric.

    Abstract: A non-woven mat of fibrous thermoplastic insulation (52, 54, 56) is produced by melt blowing recycled polyethylene terephthalate (PET). The PET is melted, pressurized and extruded from an extrusion head (5) into substantially continuous fibers (20) that are subjected to turbulent high velocity air (41) that attenuates the fibers (C). The fibers (22) are then collected on a collection device (39) building up a non-woven mat. The collection device (39) is spaced from the extrusion device (5) forming a flight path for the fibers (20) that is sufficiently long that the fibers split apart under the force of the high velocity air (41), fibrillating into a plurality of very fine fibrils (22) of under 15 microns in diameter. These fibrils (22) are analogous to goose down and greatly enhance the loft and R value of the mat.

    Abstract: The invention relates to a laminate comprising a thermoplastic film (A) that is provided with non-woven fibres that project from both sides of the film, a subsequent layer of thermoplastic material (B) being applied to one side of the film, the non-woven fibres not melting at the melting point of the thermoplastic material (B), and the non-woven fibres having at least partly penetrated into and been bonded into the thermoplastic material (B). Preferably, the non-woven fibres are synthetic fibres, optionally recycled from waste material, and the thermoplastic film (A) and the thermoplastic material (B) are of the same or virtually the same polymer composition consisting of polyolefine, more in particularly polyethylene, that has optionally been recycled from waste material. The invention also relates to a process for the manufacture of such a laminate in which at least a thermoplastic film (A) provided with non-woven fibres that project from both sides of the film is rolled and/or pressed onto a layer of thermoplastic material (B) at a temperature at which the fibres do not melt, the non-woven fibres at least partly penetrating into and being bonded into the thermoplastic material (B). Preferably, the thermoplastic film (A) provided with non-woven fibres that project from both sides of the film is rolled and/or pressed onto the plastic, hot mass during the production of the thermoplastic material (B).

    Abstract: An axially extending tubular composite member (100) having a plurality of plies and extending along a longitudinal axis has at least three plies (116, 118, 120) with selectively structured fiber components in each ply. Typically an inner ply (116) has at least one biaxial fiber component, an intermediate ply (118) has at least an axial fiber component that typically is combined with two further fibers to form a triaxial fiber component. Another ply (120) typically has a woven fiber component. A further ply having a biaxial component either replaces the ply of woven fiber or is disposed beneath it over the intermediate ply. A surface veil (122) having fiber and an excess of resin material typically covers at least the innermost or outermost surface of the composite member. An internal web member (112, 114) can be provided, and typically also employs fibers and the matrix material.

    Abstract: The invention relates to a ballistic resistant material having a V50 value of at least about 1000 feet per second. The ballistic resistant material includes at least two types of fibrous materials, which are blended and consolidated together, preferably by needlepunching, to create a single layer of nonwoven, composite material. The needle punching is preferably in the range of 200 to 1000 needlepunches per square inch. The fibrous materials are characterized by being deformed when subjected to the impact of a ballistic object. One of the fibers phase changes, e.g. melting, upon impact and at least one other fiber fibrillates upon impact. One of the fibers must phase change at a temperature at least 80 DEG C lower than the highest melting or destruction point fiber in the high modulus fiber blend.
