Definitions

  • a flame-retardant composite article comprising a core of one or more combustible materials, at least partly covered by a combination of (a) one or more flexible intumescent char-forming materials, and (b) one or more textile fibrous layers, said combination forming at least one layer or zone.
  • any normally-combustible cushioning material may be used for the core of the flame-retardant composite articles of this invention.
  • foams commonly used in the manufacture of furniture, upholstery and bedding e.g. polyurethane foam, latex foams and the like
  • suitable cushioning materials include soft fibrous felts, coiled hair and the like.
  • the intumescent materials used in the present invention are materials which form a viscous liquid froth when first exposed to a flame, the froth being converted to a rigid carbonaceous char as heating continues.
  • Particularly suitable intumescent materials for the purpose of this invention are the intumescent polyurethane foams produced in accordance with the process of U.S. Pat. No. 3,681,273.
  • One such intumescent foam is commercially available as PYREL from Scott Paper Company. (PYREU is a Registered Trade Mark).
  • Wool batting is another suitable intumescent material for use in the present invention.
  • the fibrous textile material may be in the form of a woven, non-woven or knitted fabric.
  • Each layer of textile material may be situated either inside or outside the layer of intumescent char-forming material, so that each layer of textile material is in contact with said intumescent char-forming material. (The expressions inside” and outside are used with reference to the combustible core).
  • the layer of textile material When the layer of textile material is situated outside the intumescent material, it may take the form of a decorative covering material for the composite article.
  • the composite article may be provided with a separate, preferably decorative, covering layer.
  • any textile material may be used. However, it is preferred to use a textile material which on burning leaves a charred skeleton (e.g. cotton and rayon).
  • a textile material which on burning leaves a charred skeleton e.g. cotton and rayon.
  • the textile material may be made from fibres which have been coated with an intumescent material.
  • the textile material may be made from more than one set of fibres, at least one of such sets of fibres being fibres made from an intumescent material.
  • the flame-retardant composite articles of the present invention may be used as cushioning materials in any application where there is a fire risk, e.g. furniture upholstery, bedding and the like.
  • Example 2 Each of the above samples was subjected to a flame from a small propane blow-torch, the propane gas being burnt at 0.4 g/minute. In all cases, ignition of the EXAMPLE 2 Test samples similar to those of Example 1D were prepared, using different thicknesses of the flame retardant intumescent char-forming foam, different methods 0f fixing this foam and the fabric around the polyetherurethane foam block, and different fabrics. These samples were suspended and ignited by a match.
  • Samples F to N were covered with the moquette fabric of Example 1.
  • Samples 0, P, Q were covered with a damask weave fabric having 84 threads per inch of 24-count span rayon in the warp and 43 threads per inch of 400 denier continuous viscose rayon filament in the weft, and weighing about 150 g/m
  • Samples R, S were covered with a plain-weave fabric having 60 threads per inch of 20-count cotton yarn in both the warp and the weft, and weighing about g/m The results are shown in the Table below:
  • a crumpled sheet of newspaper was placed on a wiremesh-topped table, the covered foam cube was placed on top of this, and encircled by two further crumpled sheets of newspaper, the sheets being stapled together so as to ensure close contact between the paper and the sample throughout the test;
  • the weight of newspaper used was about 50 g.
  • EXAMPLE 4 An intumescent, non-cellular polyurethane was prepared from the following formulation:
  • FOMREZ 50 is a partially-branched diethylene glycol polyadipate having a hydroxyl number of approximately 50. (*FOMREZ is a Registered Trade Mark).
  • PU-l604 is an isobutyl ester of 4-chloro-3,5-
  • EDA 260 is a substituted ethylene diamine having the formula e) PHOSCHEK P-30 is an ammonium polyphosphate (PHOSCHEK" is a Registered Trade Mark.)
  • a square-woven cotton fabric I76 g/m was coated on one side with a 0.6 mm-thick layer of the noncellular polyurethane described in the immediately preceding paragraph.
  • the coated fabric was heated at 100C for 20 minutes to complete the polyurethaneforming reaction, before being used to cover a 10 X 10 X 10 cm cube of flexible polyurethane foam.
  • the covered cube was subjected to the burning test of Example 3 (above). At the end of the test. percent of the foam was found to be intact.
  • HYPALON 20 is a chlorosulphonated polyethylene (HYPALON is a Registered Trade Mark).
  • CERICLOR 70 is a chlorinated aliphatic hydrocarbon mixture containing 70% chlorine by weight. (CERICLOR is a Registered Trade Mark).
  • a square-woven nylon fabric (210 g/m was coated on both sides with the above-described HYPALON formulation. After subjection of the coated fabric to the burning test of Example 3 (above), using a 10 X 10 X 10 cm cube of polyurethane foam as the core, no weight-loss of the foam occurred, the core being only slightly discoloured.
  • EXAMPLE 6 A 10 X 10 X 10 cm cube of polyurethane foam was covered with the HYPALON foam of Example 5 and the rayon damask fabric of Example 2P, and the composite was subjected to the burning test of Example 3. No weight-loss occurred in the foam core.
  • the batt-fabric composite was used to cover a 10 X 4 X 2 cm block of polyurethane foam.
  • the covered foam block was then suspended 1 inch above 15 g of crumpled newspaper, the newspaper then being ignited and allowed to burn completely.
  • EXAMPLE 8 Two sheets of the wool batt of Example 7 were needled on either side of a sheet of the FY REL foam of Example 3.
  • the batt PYREL composite was used to cover five faces of a l l X l 1 X 5 cm block of polyurethane foam, the sixth face of the foam being covered by an 1 1 X l 1 cm piece of 3-mm hardboard.
  • the composite article so formed was then covered with a sheet of square-woven cotton fabric (120 g/m the fabric and batt PYREL composite being secured to the underside of the hardboard by means of wire staples.
  • the composite was suspended flat" at a height of 4 inches above 30g crumpled newspaper (the hardboard-covered surface being nearest the newspaper), which was then ignited and allowed to burn completely.
  • the composite was then suspended so that the hardboard surface was vertical. one corner being at a height 4 inches above a further 30g crumpled newspaper.
  • EXAMPLE 9 The wool batt of Example 7 (above) was needled to both sides of a 5 mm sheet of PYREL foam.
