Definitions

  • the present invention relates to yarns and fabrics that present simultaneously high flameproof, heat resistant, and insulating characteristics, to their manufacturing process, and to their use for the manufacturing of flameproof, heat resistant, and insulating products.
  • the fabrics manufactured with the above-mentioned fibres even with their various advantages, nevertheless also present various disadvantages that make their use uncomfortable; in particular, the products manufactured with these fabrics have a significant permeability to heat (and thus, even if they are fireproof, do not allow the operator to be exposed for a long time to the heat source) and, in contact with flames, easily tend to melt or carbonize, and then to disintegrate. Moreover, these materials are difficult to be processed when they have to be manufactured (as, for example, in the manufacturing of fireproof garments).
  • the present invention relates to fabrics consisting of pre-anodized acrylic fibres.
  • the present invention allows to overcome the above-mentioned problems, thanks to fabrics comprising the fibres as defined above.
  • pre-anodized acrylic fibres we mean the fibres having this name normally used in the textile field, as for example those manufactured by Ashai Chemicals (LASTAN®), Toho Rajon (PIROMEX®), SGL (PANOX®), and Zoltek (PYRON®), and their blends.
  • the fabrics according to the present invention can be prepared, for example, accordinging to the process related here following and subject too to this patent application.
  • the fibres, in flocks are spun obtaining both single and twisted yarns, having a metric number (that is metres, in thousands, per 1 Kg) between 10 and 60.
  • the yarns are dried by heating them on hot rolls (calendering).
  • the yarns so obtained can then be used in the manufacturing operations according to the normal weaving techniques of fabrics having any type of weave, for example from plain weave to satin, in which the yarn can be both woven and warped.
  • the fabrics according to the present invention find a very wide use, for example in the manufacturing of protective clothing for fire-fighting operations, and military, industrial, sports use, etc. Moreover, they can be used in the manufacturing of structures useful for the protection of materials and plants from fire, or the flameproof textile upholstery and accessories for furnishing public areas like cinemas, theatres, discotheques, seats, etc..
  • the fabrics comprising only pre-anodized fibres have an exceptional heat resistance, that make them particularly suited to the manufacture of insulating elements (for example panels for fire doors, carters for protecting engines or machine parts, insulating elements for boots and similar equipment, etc.).
  • insulating elements for example panels for fire doors, carters for protecting engines or machine parts, insulating elements for boots and similar equipment, etc.
  • the felt ones are specially preferred.
  • the felt according to the present invention is prepared, for example, according to the process hereinafter described which is also a subject of the present application.
  • the pre-anodized fibres, in flocks, are turned into veils through the carding process; these veils are then needle felted so as to obtain the desired uniformity and solidity in the finished product.
  • the product's solidity is a function of the number of veils, the number of needles per square metres used, and the number of beatings carried out in the needle felting process (the higher the number of veils, needles, and beatings, the more solid ans resistant the product will be).
  • the felts having an areal mass higher than 100 g/m 2 are specially preferred.
  • finished felts having various thickness can be needle felted together, with the same number of needles and beatings previously specified; this so as to obtain new finished felts having a total number of veils, needles used, and beatings that are the sum of the veils, needles, and beatings of the original felts. This further improves the toughness and resistance of the finished product.
  • the felt after being needle felted, can be quilted with a yarn, in more or less large stitches, containing 100% of pre-anodized acrylic fibres, or these pre-anodized acrylic fibres in a blend with aramidic, or metal-aramidic, or para-aramidic fibres; or with a yarn comprising 100% aramidic, or metal-aramidic, or para-aramidic fibres; or again, during the needle felting process a net made in a mechanically resistant material (for example a Kevlar ® net) that will make up a weave for the same felt can be added inside the felt.
  • a mechanically resistant material for example a Kevlar ® net
  • the net can be applied on one of the felt surfaces through the usual lamination or sizing techniques.
  • the felts manufactured according to the invention comprising 100% in pre-anodized acrylic fibres like PANOX ® and LASTAN ® , underwent some resistance tests that gave the following results:
  • oxy-hydrogen flame resistance tests have been carried out, to verify the drilling times of that same flame on a felt having an areal mass of 108 g/m 2 (100% pre-anodized acrylic fibres of the PANOX ® tipe), with an average thickness of 1,62 mm, at a distance of 15 cm from the nozzle of the oxyacetylene burner and a 800° C temperature.
  • the drilling time has been higher than 3 minutes, and the temperature at the opposite side, at 3 cm from the felt, before the drilling, never exceeded 50° C.
  • the fabric according to the present invention can be laminated, sized, spread, and quilted with any other type of fabric to give the garment the desired characteristics.
