Definitions

  • Textile fibre webs are widely used for bed mattress fillings to provide a structure which is both comfortable and resilient. To comply with fire safety requirements, the characteristics of the filling material must ensure resistance to smouldering and flaming ignition.
  • bed mattress fillings are produced either from a polyester staple fibre or from a cellulosic, usually cotton, fibre.
  • Polyester-based mattress fillings demonstrate good load bearing characteristics and are non-ignitable with smouldering cigarette and small flaming ignition sources. However, such fillings have a tendency to melt under the influence of an ignition source and thus may expose lower layers of the filling assembly to ignition.
  • Cotton based fillings have reduced load bearing characteristics but show an ability to absorb moisture (perspiration) and thereby provide a more comfortable sleeping surface. When subjected to an ignition source, cotton will char to form a protective barrier, but progressive smouldering of the cotton occurs. Conventionally, cotton materials are chemically treated to prevent smoulder and a common method is to apply approximately 10% by weight of boric acid powder.
  • An object of the present invention is to provide a blend of textile fibres for a bed mattress filling which improves fire safety performance without the need to apply fire-retardant chemicals but yet provides the comfort and load bearing characteristics of cellulosic and polymeric fibres.
  • a blend of cellulosic fibre and a polymeric fibre having a melting temperature lower than its temperature of decomposition for ensuring resistance to both shouldering and flaming ignition of a bed maitress fibre filling material including said blend, wherein the cellulosic fibre represents between 45wt% and 65wt% of the blend and the polymeric fibre represents between 35wt% and 55wt% of the blend, and wherein no fire retardant chemicals are used.
  • the cellulosic fibre represents between 50wt% and 65wt% of the blend and the polymeric fibre represents between 35wt% and 50wt% of the blend.
  • a textile fibre web for use as a bed mattress filling material comprises a blend of polyester and cotton fibres.
  • the web of fibres may be formed by any standard web forming technique for example carding and cross laying, air laying, straight laying, and may be provided as a non-bonded web, a chemically bonded web, a thermally bonded web or a mechanically bonded web, for example by needling.
  • Cotton rich blends are prone to smouldering ignition and polyester rich blends are prone to flaming ignition.
  • a range of blend proportions is provided wherein smouldering ignition is prevented by polyester additions and flaming ignition is prevented by cotton additions. In broad terms this range is represented by between 45wt% and 65wt% cotton and between 33wt% and 55wt% polyester with the preferred range being from 50wt% to 65wt% cotton and from 35wt% to 50wt% polyester.
  • the polyester fibres are typically 1.7 dtex to 50 dtex with a staple length of between 25mm and 100mm.
  • the product weight range is typically from 50grams per square metre to 4,000 grams per square metre depending upon the intended use. For example, a lightweight filling at 300 grams per square metre may be used to provide a protective fire resistant cover or layer superimposed on less fire resistant materials where a web of 1,500 grams per square metre may be used.
  • a blend of fibres of composition Polyester 17 dtex 60mm 15wt% Cotton 50wt% Polyester 4.4 dtex bicomponent 35wt% was formed into a web using an air laying machine and was thermally bonded at a temperature of 160°C to produce a bonded web.
  • the product had a weight of 1200 g/m 2 and a thickness of approximately 60mm making it ideally suited for use as a bed mattress filling material.
  • the increased bulk (thickness) and the increased support demonstrate a significant increase in filling performance of the example product.
  • a bed mattress comprising a non-fire retardant insulator pad and the example product as a filling gave the following results when tested for ignitability.
  • a blend of fibres of composition Polyester 7 dtex 60mm 35wt% Cotton 65wt% was formed into a non-bonded web by carding and cross lapping. The web was layered on to a paper carrier to assist handling. The non-bonded web had a weight of 300g/m 2 .
  • the example product was used as the top layer in a bed mattress filling assembly and imparted non-ignitable properties to the fillings assembly and to the bed mattress as follows.
  • BS EN 597 - 1 (cigarette test)
  • BS EN 597 - 2 (match test)
  • no ignition BS 6807 ignition source 5 no ignition BS 7177 low hazard (including ignition source 0/NS no ignition
  • the filling may contain additional components representing no more than 20wt% of the overall blend.
  • additional components representing no more than 20wt% of the overall blend. Examples are wool, PVC and some acrylics having a melting temperature greater than their temperature of decomposition. Such additional components could enhance the fire retardant properties of the product.
