Definitions

  • the present invention relates to a heat-resistant garment providing protection against contact heat.
  • Heat-resistant garments have been described in the literature into large detail. Many heat-resistant garments have been proposed to parts of human or animal bodies, such as hands, arms, legs, feet or trunk against radiation heat or contact heat.
  • Metal wires have also been described for protective garments, such as heat-resistant garments. Reflective textile products are known to protect human or animal bodies against radiation heat. The use of aluminised strands is known from AU513103. Also the use of metal filaments as a reflecting stand was mentioned in this document.
  • the heat-resistant garment looses its thermal insulating character and its mechanical properties.
  • the present invention relates to a heat-resistant garment having an outer surface mainly comprising metal fibres to provide a resistance against contact heat.
  • a heat-resistant garment having an outer surface mainly comprising metal fibres to provide a resistance against contact heat.
  • the garment In case a garment is to resist radiation heat, e.g. used as heat-resistant garment to protect the used against heating due to this radiation, the garment has to reflect as much as possible the energy, provided by the radiation of a heat source (e.g. fire, radiant burners, glowing objects). This reflection hinders the garment to be heated.
  • the garment is to be provided by reflective material and is preferably as dense as possible.
  • a garment In case a garment is to resist contact heat, the garment itself is heated due to energy provided via heat conduction.
  • the garment is to absorb the energy, or in any case, prevent the energy to pass though the garment towards the object, which is protected by it.
  • a heat-resistant garment comprising one or more textile layers of which the outer textile layer is a heat- resistant textile fabric comprising metal fibres at the outer surface.
  • the outer surface of the garment is to contact the hot objects.
  • a metal fibre content of this outer surface of 50% to 100% by weight should be used.
  • more than 70% by weight, and most preferably more than 80% by weight should be metal fibres.
  • An outer surface comprising only metal fibres gives also good results.
  • the non-metallic fibres, used to provide the outer surface next to the metal fibres, are to be heat-resistant textile fibres e.g.
  • para- aramid fibres meta-aramid fibres, glass fibres, ceramic fibres, carbon fibres, preox-fibers, poly(p-phenylene-2,6-bezobisoxazole), hereafter also called PBO, or polybenzimidazole fibres.
  • Such a heat-resistant garment is resistant to high contact temperatures, depending on the ratio of metal fibres to non-metallic fibres, the type of non-metallic fibres, if any, and the type of metal alloy, used to provide the outer surface.
  • the presence of metal fibres increases the resistance against mechanical actions under higher temperature and it was found that the presence of metal fibres at the outer surface of the heat-resistant garment does not diminish, or even improves the insulating properties of the heat-resistant garment. This is surprising having regard to the high thermal conductivity of metals. An explanation is as follows.
  • thermal energy provided by contact heat to the outer surface of a heat-resistant garment, will be distributed through the whole of the garment in any direction, or will be used to heat the heat-resistant material.
  • fibres with a low coefficient of heat conduction are preferably used. This to prevent the thermal energy to be conducted towards the protected object. Since this low coefficient of thermal conductivity, the thermal energy was kept in the direct neighbourhood of the hot object contacting the heat-resistant garment, where it is used to heat the heat-resistant fibres. When the temperature of the hot object is too elevated, the fibres are degenerated, since too little energy is evacuated.
  • the volume of the fibres, used to provide this fabric, is V f , being M S f (cm 3 ).
  • the filling rate of the fabric is to be understood as 100*V f /LW*D
  • the volume of all fibres present is to be taken into account.
  • E.g. 2 different fibre types with 2 different specific weights S f1 and S f2 are used.
  • the low filling rates of the heat-resistant fabrics as subject of the invention cause small contact points between the metal fibres, present either as a yarn or as such, and a large number of small open spaces between these fibres.
  • Thermal energy which is applied to the surface of the heat-resistant garment as subject of the invention, will be hindered to flow through the garment towards the protected body or object. This because these small open spaces and small contact points disturb the thermal conductivity in this direction, in spite of the good thermal conductivity of the metal fibres.
  • the thermal energy will preferably be conducted to areas of the heat- resistant garment surrounding the contact points, since the fibres, mostly lying parallel to the surface of the heat-resistant garment, will conduct the thermal energy thanks to the good thermal conductivity. Best insulating properties are found for heat-resistant garment as subject of the invention when the filling rate is below 25%, preferably less than 20% or even less than 15% or 10%
  • the filling rate may not be too small, since no material is present to conduct the thermal energy 2% may be seen as a lower limit
  • Another advantage is that the lifetime of the heat-resistant garment according to the invention is increased, since the metal fibres do not degenerate at higher temperatures, e g at 600°C to 750°C for AISI 300- type stainless steel fibres, or 1000°C for Aluchrome-type fibres
  • Heat-resistant garments as subject of the invention comprising meta- aramid or para-aramid fibres, are resistant to higher contact temperatures applied on the outer surface, compared to similar heat- resistant garment without metal fibres
  • the lifetime of heat-resistant garments as subject of the invention comprising meta-aramid or para- aramid fibres is longer than the lifetime of a similar product without metal fibres on the outer surface under same temperature circumstances
  • the metal fibres prevent the other fibres from degenerating to certain extend Further, the metal fibres help the blend to resist to a larger extent mechanical actions under higher temperatures These improvements are obtained without loosing flexibility or drapeabi ty of the heat-resistant garment compared to a heat-resistant garment without metal fibres on the outer surface
  • metal fibres are to be understood as fibres having an equivalent diameter of less than 50 ⁇ m. More preferably, an equivalent diameter of less than 25 ⁇ m., and most preferably between 5 ⁇ m. and 13 ⁇ m., such as 6 ⁇ m., 8 ⁇ m. or 12 ⁇ m. is used for the outer surface of the heat-resistant garment. With equivalent diameter is meant the diameter of a circle, which has the same surface as the surface of the metal fibres being cut radial to their axis.
  • All types of metal fibres may be used. Usually, but not necessarily, stainless steel fibres are used. Alloys such as AISI 316 or AISI 316L, AISI 347, or other alloys out of the AISI 300 type are used. Also alloys out of the AISI-400 type, Aluchrome-type alloys or alloys as described in
  • US-4597734 can be used. These fibres may be bundle drawn, as described in patent US-A-3379000, or may be made by shaving them from a coil, as described in patent US-A-4930199 or can be melt extracted. Also metal fibres produced as described in JP62260018 may be used.
  • additional layers of heat-resistant textile fabrics may be used, one on top of the other, additionally to the heat-resistant textile fabric providing the outer surface of the heat-resistant garment.
  • the other heat-resistant textile fabrics, which form the heat-resistant garment together with the heat-resistant textile fabric comprising metal fibres may be made out of other heat- resistant textile fibres such as para-aramid fibres, meta-aramid fibres, glass fibres, ceramic fibres, carbon fibres, preox-fibers, para-aramid fibres, meta-aramid fibres, glass fibres, ceramic fibres, carbon fibres, preox-fibers, poly(p-phenylene-2,6-bezobisoxazole) or polybenzimidazole fibres, or a combination thereof, and may comprise metal fibres as well.
  • layers of textile fabric providing other properties e.g. comfort during wear, cut resistance and resistance against moisture may be added, underneath the layer of heat-resistant textile fabric providing the outer surface of the heat-resistant garment.
  • the different textile layers forming the heat-resistant garment don't have to be fixed together permanently, e.g. by means of confection.
  • the different layers of the heat-resistant garment may be used separately one above another. This gives the additional advantage that in case one layer is worn out, only this layer is to be replaced.
  • the outer heat-resistant textile fabric may comprise metal fibres either distributed through the whole volume of the fabric, or only on the outer surface of this heat-resistant textile fabric, which is to provide the outer surface of the heat-resistant garment. For calculation of the filling ratio, only the depth of the fabric comprising metal fibres, and the fibre volumes providing this depth are to be taken into account.
  • the outer heat-resistant textile fabric comprising metal fibres at its outer surface, can be obtained by using different textile techniques.
  • This fabric can be, as a matter of non-limiting examples, a woven fabric, a knitted fabric, a braided fabric or a non-woven fabric.
  • the outer heat-resistant textile fabric is a woven fabric
  • different woven structures can be used.
  • the woven fabric can either be mono- or multilayer.
  • multilayer is meant that different layers of weft yarns can be found, where these different layers of weft yarns are combined one to the other by the warp yarns.
  • the woven fabric can either be in total made out of yarns comprising metal fibres, or the yarns comprising metal fibres can be located at this side of the heat-resistant textile fabric, providing the outer surface of the heat-resistant garment.
  • terry cloth where the whole or only the loops are made out of metal fibre comprising yarns, can be used, providing that the side which comprises the metal fibres is used as the outer side of the heat-resistant garment comprising metal fibres.
  • terry cloth is meant a woven fabric, which has a yarn forming loops on one or both sides.
  • the fabric can either be warp or weft knitted. Either single bed or double bed knitted fabrics for warp and weft knitted fabrics can be used.
  • the outer heat-resistant textile fabric is a weft knitted fabric

  • the knitted fabric can either be made in total out of yarns comprising metal fibres, or the yarns comprising metal fibres can be located at this side of the heat-resistant textile fabric, providing the outer surface of the heat-resistant garment.
  • a fabric with only one side comprising yarns with metal fibres, and the other side comprising yarns without metal fibres can be obtained by using the plating technique.
  • Plating technique means that two different yarns, e.g. one comprising metal fibres, the other not, are guided to the same needle, where both yarns are incorporated in the same stitch in such a way that one yarn always comes to the face side of the fabric and the other always comes on the reverse side of the fabric.
  • a single bed fabric can be obtained, with a face side comprising the yarns with metal fibres, and a reverse side comprising the yarn without metal fibres.
  • a heat-resistant textile fabric with one side comprising yarns with metal fibres and the other side comprising yarns without metal fibres can be obtained as follows.
  • the yarn with metal fibres is knitted on one needle bed.
  • the yarn without metal fibres is knitted on the other bed. Both sides so obtained are connected during knitting by e.g. tuck stitches on both beds during same course. This results in a fabric with one side with metal fibres and the other side without metal fibres.
  • the fabric can either be obtainable by needle-punching or stitch-bonding techniques.
  • the non-woven fabric can either be in total made out of one or more layers comprising metal fibres, or the metal fibres can be located at one outer side of the heat-resistant textile fabric, providing the outer surface of the heat-resistant garment.
  • the outer heat-resistant textile fabric can also be a braided product.
  • the metal fibres are present in the heat-resistant garment as staple fibres or by using yarns, of which the metal fibres are part. These yarns can comprise multifilament metal fibres or staple metal fibres.
  • metal fibres are used as staple fibres, either used to form a 100% metal fibre non-woven, or blended with other non-metallic heat-resistant fibres.
  • yarns comprising metal fibres are used.
  • the fibre materials, of which at least one are metal fibres can be intimately blended and possibly plied to a two or more plied yarn or the yarn can be a two- or more plied yarn, where some or all of the single yarns are made out of one fibre type.
