Abstract: A nonwoven interlining and nonwoven chest piece are combined and together employed to be incorporated into a garment such as jacket or coat by pressing. This is accomplished by providing thermally activatable adhesive on both faces of the combination so that steam pressing serves to join it to the garment fabric. The individual nonwoven layers are only partially prefixed or internally bonded and a further mass of resilient binder adds to the cohesiveness of the unit.

Abstract: Adhesive-coated tire cord fabric and similar fabric and single end cords for other end uses can be protected from the adverse effects of exposure to the products of combustion present in fuel oil- or kerosene-fired dryers and curing ovens as well as to atmospheric oxidation, prior to the adhesion of such fabrics to rubber, by incorporating a hydrocarbon wax which is a microcrystalline wax or a Fischer-Tropsch wax in the adhesive formulation.

Abstract: A laminate for interior finish material comprising a frame and a covering material thermally adhered to each other with a hot melt adhesive containing a polyamide copolymer of a melting point of about 80.degree. - 140.degree. C as principal component.

Abstract: A net formed integrally of blended incompatible polymers, with parallel smooth longitudinal ribs interconnected by a plurality of split strands non-uniformly interspersed with a plurality of differently sized voids, by stretching a film with a generally longitudinal set of parallel primary grooves and a transverse or angled set, on the other surface, of parallel secondary grooves.

Abstract: A crimp finished yarn wherein a mesh like structure consisting of a large number of thick filaments and a large number of thin filaments intersecting with the large number of thick filaments is formed by opening an elongated thermoplastic synthetic resin film by means of an opener, for example, by causing the film to pass between a pair of vertically disposed card clothing rollers and then this film is made to pass through a tooth-shaped roller forming a crimp applying device and a friction roller at room temperature whereby the molecular arrangement of the surface making slidable contact with the tooth-shaped roller is changed with the friction passing and compression process to form a different layer condition, and at the same time, crimps of saw-tooth condition are produced, whereby a mesh like crimped fiber structure formed by the large number of crimped thick filaments and crimped thin filaments is provided.

Abstract: In making a hard multi-tubular structure, one starts with a flat woven or knitted hose fabric comprising a plurality of side-by-side hoses; the hoses of the fabric are caused to expand and to set in their expanded configurations, which may be circular or substantially square in cross-section by a hardenable medium with which the fabric is impregnated or coated. Optionally, a hardenable covering and/or filling is provided over or in the hoses.

Abstract: A leather yarn embodies a novel combination of five parameters which enables the leather yarn to be readily worked by garment knitting machine needlework into a unique knitted fabric having a soft "leather hand".The parameters are:1. Softness;2. Consistent Thinness of Depth;3. Consistent Narrowness of Width;4. Adequate Tensile Strength; and5. Continuity.The leather yarn is cut from a thin leather having a weight in the range of about 3 oz. to 11/2 oz. as measured by a standard leather thickness gauge such as the Woburn ounce weight caliber, made by the Woburn Machine Company, Woburn, Massachusetts.The softness parameter is obtained by the selection of a leather with the softness characteristics of fine garment/dress glove leather (a standard category in the tanning industry).The consistent narrowness of width and thinness of depth (and manufacture of the yarn at a marketable cost) is obtained by a number of specifically interrelated machine cutting operations.

Abstract: A nonwoven fabric is comprised of a blend of fine staple fibers and coarse staple fibers randomly oriented with the fine staple fibers having a higher melt flow than the coarse staple fibers. In the manufacture of the nonwoven fabric, same is needled whereby the needles select the fine fibers and portions of same are positioned in a plane generally transverse to the plane of the fabric. Infrared heat is used to fuse the fine fibers at overlapping portions thereof to provide integrity for the fabric. The coarse staple fibers are held in the interstices of the fabric at least partially by frictional engagement with the fine staple fibers.

Abstract: In a strapping band comprising a tape-shaped core having continuous reinforcing fibers combined together with a thermosetting resin and an outer layer of thermoplastic resin covering the tape-shaped core, the thermoplastic and thermosetting resins each has polymeric units derived from the same monomer.

Abstract: In a self-bondable insulated wire comprising a conductor and three resin insulating layers, the first resin insulating layer is formed with a resin selected from the group consisting of polyimide resins, polyamideimide resins and polyesterimide resins, the intermediate resin insulating layer is formed with a resin selected from the group consisting of polyvinyl formal resins and epoxy resins, and the outermost resin insulating layer is formed with a self-bondable resin of phenoxy series. Thus, a self-bondable insulated wire which is excellent in both oil resistance and heat resistance is obtained.

Abstract: An assembly including a ceramic insert and a surrounding dielectric filler in a ferrite or garnet toroid is disclosed, wherein a void is provided into which the dielectric filler can expand, such as by the formation of a temporary layer of liner material on an outer surface of the ceramic insert, or on the liner surface of the toroid, or on both. The ceramic insert is inserted into the toroid, and then the void between the ceramic insert and the toroid is filled with a dielectric heat-curable composition. Then the filled assembly is heated to an elevated temperature to burn out said liner. The liner material burns at a temperature of about 100.degree. F to a temperature which is at least 20.degree. F below the curing temperature of the dielectric heat-curable composition, and preferably the liner burns at a temperature below about 300.degree. F, to leave essentially no ash adversely affecting the resulting assembly.
