Including Glass Material Patents (Class 57/229)
  • Patent number: 4433535
    Abstract: A yarn is made by carding short lengths of glass fibre and then spinning the carded fibres. Advantageously short lengths of support fibre are mixed in with the short lengths of glass fibre before carding. A reinforcing strand may be buried in the yarn during spinning or during a subsequent twisting step. The support fibre should preferably be flexible. The resulting yarn, or goods made therefrom, can be used in many applications to replace goods based on asbestos fibres or on continuous glass fibres.

  • Patent number: 4381639
    Abstract: A sheath-core yarn and methods of preparing it are disclosed. A sheath of aramid fibers surrounds a continuous filament core composed of an amorphous silica product containing at least 96% silica and having the thermal performance of a refractory material. The yarn is useful in woven or knitted safety garments which must provide protection under such severe conditions as splattering molten steel.

  • Patent number: 4343343
    Abstract: An elastomeric article and a composite cord for reinforcing an elastomeric article. The cord comprises a core spirally wrapped by at least one high tenacity, substantially inextensible yarn. The core is composed of at least one unoriented polymeric filament which has an initial modulus of elasticity of at least 1000 newtons/mm.sup.2 and an elastic limit of at least one kilogram. The core has a length at break which is greater than the length of the yarn when the yarn is fully stretched out to permit stretching out of the yarn without rupture of the core for expansion of an elastomeric article and reinforcement thereof in the expanded condition.

  • Patent number: 4313998
    Abstract: The invention relates to a new complex filiform textile element comprising fibers of an inorganic material.The element in accordance with the invention is characterized by the fact that the fibers are contained on the outside by an enveloping but open structure of metal, the total area of the openings (So) being greater than the total area of the enveloping structure (Se) covering the apparent peripheral surface of all the entire fibers.

  • Patent number: 4299884
    Abstract: There is provided a new wrapped textile thread which includes a core made of threads arranged considerably parallel to each other. The core is covered by a wrapping thread which winds in a single turn, forming a regular and joined spiral around the core. This textile thread is characterized by the fact that at least one part of the peripheral surface of the core is joined together by heat sealing with the wrapping of winding thread. The textile thread is useful in textile materials which require a very good resistance against abrasion.

  • Patent number: 4272950
    Abstract: Filiform textile material which can be used for producing a textile material used in the manufacture of laminated articles or which can be given a coating, constituted by a plurality of resin-preimpregnated continuous chemical filaments, wherein it is formed by at least one assembly having a plurality of non-polymerized or partly polymerized, resin-preimpregnated individual filaments covered by at least one layer of wrapping textile material which is not impregnated with resin.

  • Patent number: 4173113
    Abstract: The cable includes continuous glass filaments which are helically plied in rovings at a constant helical angle from cable center to outer surface and bonded together in elastomeric material. When heated, thermal elongation of the filaments is opposed by simultaneous radially directed thermal volumetric expansion of the elastomeric material. Thus, with respect to overall cable length, thermal elongation of the cable is opposed by a simultaneous increase in cable cross sectional area such that thermal elongation effects are controllable, dependent upon the thermal expansion properties of the filament and elastomeric materials used, by controlling the helical angle at which the filaments are plied to obtain either expanding, contracting or constant length cables, as desired. Thermal contraction effects produced by cooling the cable also are controllable by controlling the helical angle.
