Definitions

  • the present invention relates to fire resistant textile materials and to garments manufactured from such materials.
  • the present invention relates to articles of fire resistant clothing for use by fire fighters, military personnel and police officers, or the like, and to textiles for manufacturing such clothing.
  • Clothing for protection against heat and flame must pass minimum performance requirements for flame, radiant heat, heat resistance, tensile and tear strength, and penetration by water and liquid chemicals.
  • the assembled garments which typically include a pair of trousers/salopettes and a jacket, must protect the wearer from radiant and thermal exposure, and unexpected flashover conditions, whilst still maintaining an adequate level of dexterity and comfort.
  • a fire-resistant textile material which is lightweight, breathable, strong, durable and comfortable.
  • a cabled yarn comprising:
  • At least two single plied yarns each comprising meta-aramid fibres, para-aramid fibres, cellulose-based fibres, and wool fibres, twisted around a centrally located yarn comprising a substantially elastic fibre.
  • the cabled yarn comprises by weight at least 10% of said meta-aramid fibres.
  • the centrally located yarn comprises ethylene and at least one olefin.
  • the centrally located yarn comprises ElastolefinTM.
  • the cabled yarn comprises by weight around 23% meta-aramid fibres, around 4% para-aramid fibres, around 33% cellulose-based fibres, around 33% wool fibres, and around 7% ElastolefinTM fibres.
  • the cellulose fibres comprise a fire-retardant viscose fibre.
  • the wool fibres have a thickness of around 15.5pm to around 29.5pm.
  • the meta-aramid fibres comprise NomexTM.
  • para-aramid fibres comprise KevlarTM.
  • a fire- resistant textile material comprising a yarn according to the first aspect of the present invention.
  • a garment comprising a material according to the second aspect of the present invention.
  • a method of manufacturing a cabled yarn comprising:
  • each single plied yarn comprises by weight at least 10% of said meta- aramid fibres.
  • the centrally located yarn comprises ethylene and at least one olefin.
  • a fire-resistant textile material comprising:
  • the weave is a twill weave.
  • Figure 1 illustrates a‘cabled’ three-ply yarn according to certain embodiments of the present invention.
  • a single ply yarn includes a blend of paraphenylene isophthalamide (meta-aramid) fibres, cellulose-based fibres, wool fibres, and polyparaphenylene terephthalamide (para-aramid) fibres.
  • metal-aramid paraphenylene isophthalamide
  • cellulose-based fibres cellulose-based fibres
  • wool fibres polyparaphenylene terephthalamide
  • para-aramid polyparaphenylene terephthalamide
  • the meta-aramid fibre is NomexTM and the para-aramid fibre is KevlarTM.
  • the cellulose-based fibre is LenzingTM FR. As illustrated in Figure 1 , two of these single ply yarns 100 are twisted together with a third yarn of substantially elastic fibre 1 10 to form a‘cabled’ three-ply yarn 200.
  • the elastic fibre 1 10 is located centrally with the single ply yarns 100 twisted therearound to provide effective cover and protection to the elastic fibre.
  • the centrally located elastic fibre yarn 1 10 comprises ElastolefinTM which is
  • a fibre composed of at least 95% (by weight) of macromolecules partially cross- linked, made of ethylene and at least one other olefin. When stretched by up to 50% of its original length, it recovers rapidly to its original length.
  • composition (by weight) of the fibre components of the cabled yarn 200 is:
  • the yarn comprises at least 10% meta-aramid, and may be more subject to the wool/LenzingTM content by weight being reduced accordingly.
  • the yarn 200 may include around 2% antistatic fibres (e.g. carbon fibres).
  • the LenzingTM FR fibre has a linear mass density of around 2.2 dtex and comprises a fire-retardant viscose fibre.
  • the LenzingTM fibres offer moisture management with its efficient moisture wicking and transportation properties when worn next to the skin of a wearer in combination with its quick drying and comfort properties.
  • the wool fibres have a thickness of between around 15.5-29.5 pm, and aptly around 19.5 pm which has been found to be optimum in terms of efficient and effective transportation of moisture from the skin and across adjacent fibres.
  • the wool fibres are treated to be shrink resistant.
  • the wool fibres are hygroscopic such that they can hold up to a third of their own weight in moisture without feeling wet thereby helping to wick away sweat whilst enhancing comfort.
  • the hygroscopic properties of the wool fibres also help to regulate temperature and humidity, creating a buffer area (i.e. holds moisture without feeling wet), enhancing comfort.
  • the chemical building blocks of wool i.e. amino acids, are hydrophilic (water-liking) such that they attract and absorb water molecules into the chemical structure of the fibre.
  • Wool Water binds within the wool structure through the action of hydrogen bonds in a process known as absorption.
  • Wool is inherently antimicrobial and antistatic which enhances comfort and protection. Wool has a helical configuration in the centre of the fibre which acts like a shock absorbing spring under compression which further enhances comfort for a wearer.
  • NormexTM yarn is typically available in three types based on the linear mass density (2.2 dtex, 1 .7dtex and 1 .4dtex). Aptly, a 1.4dtex NomexTM yarn is used as it offers desirable comfort and flexibility in view of its fineness.
  • the XLA fibres have a linear mass density of around 1 17 dtex.
  • XLA is particularly fire-resistant, robust and accommodates high levels of activity and movement to provide enhanced comfort for many different applications.
  • KevlarTM is a preferred para-aramid fibre in view of its high strength, chemical resistance, excellent durability and thermal stability.
  • the para-aramid fibre is around 1 .7 dtex / 50 mm staple length as it is aptly a spun yarn.
  • the cabled three-ply yarn 200 is aptly used to provide a textile according to certain embodiments of the present invention which may be used for a fire-resistant garment, e.g. a fire fighter’s jacket.
  • the weave is aptly a 2x2 twill weave but other suitable weave patterns may be used such as a plain weave, 2x1 , 3x1 , 4x1 or 2x2 twill weaves, ripstop or hopsack weaves, satin, or sateen weaves, or the like.
  • a 2x2 twill weave is desirable because it allows movement when shrinking down the fabric for stretch due to float size.
  • a twill weave also desirably provides a tighter, denser construction which enhances the dimensional stability and increases durability after multiple washing.
  • the cabled three-ply yarn 200 is in both warp and weft directions to desirably provide stretch in all four directions (horizontally, vertically, and diagonally) thereby providing optimal comfort to a wearer of a garment made from the textile.
  • the textile is scoured, heat sett and pressed to provide a smooth and comfortable garment.
  • Such a garment may include trousers, salopettes, jackets, overalls, T- shirts, facemasks, falsehoods, or the like. Applications for such a garment may include tackling wild land fires, electric arc protection, petrochemical applications, search & rescue, forestry, police violent situation/riot protection, military, or the like.
  • the final yarn may comprise more than three plies, e.g. four or more plied yarns twisted around a centrally located and substantially elastic yarn.
  • the final yarn may include antistatic fibres.
  • a multi-ply yarn is often known as a cabled or hammer yarn.
  • a key technical advantage of utilising these yarns in personal protective equipment (PPE) applications, particularly fire-resistant garments, is to provide a stretch material to maximise comfort whilst maintaining strength and integrity and offering sufficient protection against flame and heat.
  • the aramid fibres offer strength and robustness to withstand wear during use and to hold the material together during flaming/extreme heat exposure, whilst the XLA fibres provide desirable stretch.
  • the ‘maypole’ construction of the cabled yarn desirably protects the centrally located XLA yarn against flame, heat, UV, or the like.
