Definitions

  • the invention relates to a yarn and a woven textile made from the yam for protective clothing.
  • motorcyclists' protective clothing has been made from leather which offers good protection against abrasion and sufficient shock absorption to protect the wearer in the event of an accident.
  • German Patent Application DE-A-196 42 912 (Woods) teaches a protective textile from which protective clothing such as motorcyclist's clothing can be made.
  • the protective textile has two layers.
  • An outer layer is made from fibres which have a high disintegration textile and high mass in order to provide protection from abrasion.
  • the inner layer is designed to act as a shock-absorbing layer.
  • a liner laminate known as a Z-liner, made using the techniques disclosed in EP-B-0 081 850 (Kleis) for use in motorcycle protection suits.
  • This laminate consists of a waterproof but water vapour permeable functional layer, made of expanded polytetrafluoroethylene (ePTFE), and an outer shell of polyamide 6.6 or polyester.
  • ePTFE expanded polytetrafluoroethylene
  • This laminate has the disadvantage, however, that when it becomes wet, water is collected between the outer shell and the functional layer and the protective clothing becomes substantially heavier.
  • Kevlar® yarn An outer shell made of para-aramid yarn, such as Kevlar® yarn, would offer a suitable compromise between the weight of the clothing and the degree of protection offered to the wearer in the event of an accident. However, this yarn cannot be coloured and is therefore unsuitable for use where fashion or safety considerations dictate that the protective clothing needs to be coloured. It would be possible to use an outer shell made from a polyamide yarn, such as Cordura® yarn, which can be coloured. However, this is not as robust as Kevlar® yarn and is therefore unsuitable for protective clothing. A further disadvantage of the Kevlar® yarn is that it disintegrates in ultra-violet (UV) light.
  • UV ultra-violet
  • PBI fibres are, however, not colourable and thus this yarn is also unsuitable for use in applications in which the protective clothing needs to be coloured.
  • US Patent US-A- 4 868 041 (Yamagishi et al.) assigned to Toyo Bodeki K.K. teaches cloth made from yarns which have a core-sheath type structure.
  • the core of the yarn is made from a polyamide fibre and cotton fibres are disposed about the core to form the sheath.
  • the material is used to weave cloth offering protection against high temperature and flames.
  • an undyed wholly aromatic aramid fibre preferably para-based aramid fibre
  • light-resistant short fibres such as cotton or multifilament
  • US Patent US-A-4 381 639 teaching a sheath-core yarn for use in safety garments to provide outstanding abrasion resistance and protection at high temperatures.
  • the yarn having a sheath of aramid fibres surrounds a continuous filament core composed of an amorphous silica product containing at least 96% silica and having the thermal performance of a refractory material.
  • US Patent US-A-4 331 729 describing a yam having high temperature resistance suitable for protective garments and clothing.
  • the yarn having a central core of low abrasion resistance material wrapped with a covering also resistance to high temperature but being abrasion resistent.
  • the cover is preferably of aramid fibres, e.g. blends of aramid fibres like Kevlar®.
  • a yarn comprising a core made from a core fibre having a longitudinal tensile strength greater than 0,8cN / dtex and a sheath disposed about said core made from sheath material having a high abrasion resistance and having polyamide fibre, said polyamide fibre having particle receptors, which are amorphous areas in the fibre structure in which particles can be held by physical bond.
  • This construction allows the manufacture of yarns which are extremely strong, abrasion resistant and colourable.
  • the sheath protects the core from degradation in its tensile strength that might occur, for example, by exposure to UV light.
  • the core material has a high tensile strength, there is no requirement to chose the sheath material such that this material also provides the final yarn with a high tensile strength.
  • material may be chosen which is highly abrasion resistant and has further advantageous properties such that it can be dyed or treated with
  • particle receptors means that the fibres in the sheath material are able to physically bond with other particles.
  • Some fibres have amorphous areas in their structure in which particles, such as dye particles, may be held by van der Waal's forces.
  • particles include dye particles for colouring the fibres, water-resistant chemicals for improving the water resistance of the yarns made from the fibres or softeners for softening the yarns.
  • the core fibre of the yarn may be made from aramid fibres, polyamide fibres, polyethylene, graphite, glass, steel or polytetrafluoroethylene fibres and the sheath material is selected from the group of materials comprising polyamides.
  • the core fibre is a para-aramid fibre such as a KEVLAR ® fibre and the sheath material is polyamide 6.6 such as CORDURA®.
  • This combination has the advantage that the para-aramid fibre is protected from ultra-violet light which is known to degrade its strength properties and the polyamide 6.6 fibre has particle receptors which are amorphous areas in the fibre structures in which particles can be held by physical bonds.
  • sheath material is made of polyamide, then in addition reactive -NH 3 groups are present in the structure to which particles may chemically bond.
  • the yarn may be made into a woven textile layer for lamination onto a waterproof and water vapour permeable functional layer.
  • a textile is thus obtained which is not only highly abrasion resistant but also waterproof and "breathable".
  • Such a textile has a variety of uses in protective clothing such as protective clothing for motorcyclists.
  • at least one backer fabric is laminated onto the other side of said functional layer. This backer fabric can act as a thermal insulation layer and/or as a liner to improve the comfort of the clothing made from the textile.
  • the textile layer is woven from the yarn of the invention together with a second yarn to obtain a textile layer having a weight between 100 and 500 g/m 2 , and most preferably, between 250 and 500 g/m 2 .
  • This second yarn is made from a material chosen from the group of polyamide, polyester, polybenzimidazol and cotton and is most preferably a polyamide yarn.
  • the functional layer is a membrane or a film and can be made from the group of materials consisting of polyesters, polyamide, polyolefins, polyvinylchloride, polyketones, polysulfones, polycarbonates, fluoropolymers including polytetrafluoroethylene, polyacrylates, polyurethanes, copolyetheresters, copolyetheramides. Most preferably the functional layer is made from expanded PTFE which is known to be highly waterproof and breathable.
  • Waterproof as used herein is meant having water-penetration-resistance (hydrostatic resistance) of 0.13 bar or more. This measurement is carried out using by placing a test sample with an area of 100 cm 2 under increasing water pressure. For this purpose, distilled water with a temperature of 20 ⁇ 2°C is used and the rate of increase of the water pressure was 60 ⁇ 3 cmH 2 O/min. The water penetration resistance of the sample is then the pressure at which water appears on the opposite side of the sample. The exact method of carrying out this test is given in the ISO Standard No. 811 from 1981.
  • Water vapour permeable as used herein is meant having a water-vapour-transmission rate RET of under 150 (m 2 .Pa) / W.
  • the water vapour transmission rate is measured using the Hohenstein MDM Dry Method which is explained in the Standard-Prüfvorschrift (Standard Test Rules) No. BPI 1.4 dated September 1987 and issued by the Be reliesphysio striges Instituts e.V. Hohenstein, Germany.
  • the term functional layer is used to denote a layer which has the properties that it is both waterproof and water-vapour permeable.
  • yarn is used in the description is used to describe the continuous strands of material which are made into the textile. It includes strands, filaments, fibres and the like.
  • dtex is equivalent to g per 10,000 m of yarn. So, for example, yarn of 500 dtex has a weight of 500 g per 10,000 m of yarn.
  • Fig. 1 shows a protective suit 10 for a motorcyclist made from the yarn according to this invention.
  • a textile laminate 20 from which the protective suit 10 according to the invention is made is a three layer laminate in which an outer shell fabric 30 is made from a woven, non-woven or knitted yarn manufactured according to this invention.
  • the outer shell fabric 30 is laminated onto the upper surface of a functional layer 40 on which other side is laminated a backer fabric 50.
  • the functional layer 40 is formed in one embodiment of this invention from a porous polymeric layer 60 and a continuous non-porous hydrophilic water vapour permeable polymer layer 70 as is shown in Fig. 2b.
  • the porous polymeric layer 60 preferably used in this invention is a microporous polymer membrane having a microscopic structure of open, interconnecting micro voids. It exhibits air permeability and as such imparts, or does not impair, water vapour permeability.
  • the microporous membrane used in the textile laminate 20 described herein is typically of a thickness of 5 ⁇ m to 125 ⁇ m, most preferably of the order of about 5 ⁇ m to 25 ⁇ m.
  • the useful polymers of the microporous membrane material include plastic polymers as well as elastomeric polymers.
  • suitable polymers include polyesters, polyamide, polyolefins, polyketones, polysulfones, polycarbonates, fluoropolymers, polyacrylates, polyurethanes, copolyetheresters, copolyetheramides and the like.
  • the preferred polymers are plastic polymers.
  • microporous polymer membrane material is expanded microporous polytetrafluoroethylene (ePTFE). These materials are characterised by a multiplicity of open, interconnecting microscopic voids, high void volume, high strength, soft, flexible, stable chemical properties, high water vapour transfer and a surface that exhibits good contamination control characteristics.
  • ePTFE expanded microporous polytetrafluoroethylene
  • the continuous water vapour permeable polymer layer 70 is a hydrophilic polymer.
  • the hydrophilic layer selectively transports water by diffusion but does not support pressure-driven liquid or air flow. Therefore moisture, i.e. water vapour, is transported but the continuous layer of the polymer precludes the passage of such things as air-borne particles or micro-organisms.
  • This characteristic imparts to the textile 20 including the porous polymer layer 60 and in turn to articles made from it, such as protective suits 10, good contamination control characteristics by functioning as a barrier to contaminants of all sizes.
  • the water vapour transmitting characteristics of the material allow for comfort characteristics to the wearer.
  • the continuous water vapour permeable polymer layer 60 is typically of a thickness of between 5 ⁇ m and 50 ⁇ m, preferably between about 10 ⁇ m and 25 ⁇ m. This thickness has been found to be a good practical balance to yield satisfactory durability, continuity and rate of water vapour transmission.
  • the continuous water-vapour permeable polymers most useful herein are those of the polyurethane family, the silicone family, the co-polyetherester family or the co-polyetherester amide family.
  • Suitable co-polyetherester hydrophilic composition may be found in the teachings of US-A-4 493 870 (Vrouenraets) and US-A- 4 725 481 (Ostapachenko).
  • Suitable hydrophilic compositions are described in US-A- 4 2340 838 (Foy et al.).
  • Suitable polyurethanes maybe found in US-A-4 194 041 (Gore).
  • a preferred class of continuous, water vapour permeable polymers are polyurethane, especially those containing oxyethylene units, such as described in US-A-4 532 316 (Henn), Typically these materials comprise a composition having a high concentration of oxyethylene units to impart hydrophilicity to the polymer.
  • the concentration of oxyethylene units is typically greater than 45% by weight of the base polymer, preferably greater than 60%, most preferably greater than 70%.
  • the functional layer 40 used to make the laminate 20 of this invention can be prepared according to the teachings of US-A- 5 026 591 (Henn et al.). This method is illustrated but not limited to the following description of a four roll stack as shown in Fig. 3. Metered control of the molten water vapour permeable polymer 100 is provided for by a gravure roll 110 and a doctor blade/polymer reservoir 120.
  • the water vapour permeable polymer 100 is applied as a thin, continuous liquid film 105 to the continuously moving porous polymer membrane 130 in the nip 140 between two rotating rolls 150, 160; the first one of the rotating rolls 150 having been coated with the liquid polymer and the second one of the rotating rolls 160 providing support so as to force the liquid polymer partially into the porous structure of the polymer membrane 130.
  • Fig. 4 shows only the lamination of one fabric layer, i.e. either the outer shell fabric 30 or the backer fabric 50, onto one side of the functional layer 40.
  • a dot pattern of heat-curing adhesive 170 from a doctor knife/adhesive reservoir 180 is metered onto the second side of the functional layer 40 by a gravure roll 190.
  • the functional layer 40 is held under minimal tension against the gravure roll 190 by a low durometer rubber roll 200 at a pressure sufficient to effect removal of the adhesive dots onto the second side of the composite layer 5.
  • the adhesive dot coated composite layer 220 is brought to a laminating roll 230 where it is brought in intimate contact with the backer fabric 50 or outer shell fabric 30 provided from a storage roll 240.
  • the laminate 250 created is cured at around 125°C and is then wrapped around a storage roll 260.
  • the laminate 250 is taken up on a storage roll 290.
