Definitions

  • the present invention relates to a method of producing a flexible protective layer which can form part of various body-protecting products in order to prevent injuries caused by penetrating objects, such as nails, pointed weapons and the like, in which polymer fibers with high ultimate strength are embedded in a hardenable binder, so that the latter surrounds the fibers and, after hardening, fixes the fibers in the positions in which they are located.
  • the invention also relates to a flexible protective layer which can form can form part of various body-protecting products, and also footwear and articles of protective clothing with such protective layers.
  • U.S. Pat. No. 1,701,611 describes footwear with a flexible metal insert which comprises a woven metal wire fabric.
  • metals are usually good conductors of both heat and electricity.
  • Shoes with metal inserts therefore impair the possibility of keeping the foot warm in a cold climate and can, on account of their conductive capacity, constitute risks in some workplaces and for certain occupational groups such as, for example, electricians.
  • WO 99/13744 describes a variant of a protective boot with layers of synthetic fiber fabric integrated into the sole.
  • the fibrous fabric is not impregnated with binder in the sole but can, for example, be fitted in a pocket formed between the inner and the outer sole of footwear.
  • a main object of the present invention is to provide a method of producing a flexible protective layer which can, for example, be used in footwear as anti-nail protection, affords improved protection and can consist of relatively thin and light layers.
  • the invention is based on the insight that this aim can be achieved by using fibers made of a synthetic material with high ultimate strength, which fibers are not woven or otherwise joined together so that they form a regular structure before they are embedded in the binder.
  • the particularly characteristic feature of a method of the type indicated in the first paragraph is that the fibers are embedded in the binder in an unarranged state in relation to one another.
  • the protective layer will therefore consist of a binder layer reinforced with fibers which are located close together and are fixed in random positions relative to one another.
  • a layer with randomly oriented fibers has been found to have very great resistance to penetration and to constitute extraordinarily good protection against penetrating objects such as nails, pointed weapons and the like.
  • the fibers prefferably be felted together to form a handleable product before they are embedded in the binder. This facilitates handling of the fibers and thus the manufacture of the protective layer without the fibers having to be structured as in a woven fabric or the like.
  • DYNEEMA® high-molecular polyethylene fiber sold under the trademark DYNEEMA® which, as a consequence of its properties, inter alia a very high ultimate strength and great rigidity, has been found to afford extraordinarily good protection against penetration when, for example, fibers made of this material are molded integrally, in an unarranged state, in a shoe sole, suitably made of polyurethane.
  • FIG. 1 illustrates a shoe made with a sole with a protective layer according to the invention.
  • FIG. 2 is a cross section through the shoe according to FIG. 1.
  • FIG. 3 is an enlarged part of FIG. 2.
  • FIGS. 1 and 2 show a protective shoe according to the invention with an upper part 1 which, if desired, can be made with a protective cap (not shown) of conventional type.
  • Reference number 2 indicates an outsole, suitably made of polyurethane, and reference number 3 an insole made of a comfort-improving material.
  • the designation 4 indicates a layer for protection against penetration by nails or other sharp, penetrating objects when trodden on.
  • This layer consists of a fibrous material which is molded integrally in the polyurethane material of the outsole 2 , so that the fibers in the layer 4 maintain the relative positions they adopted in connection with the molding process.
  • the fibrous material is therefore completely impregnated with the polyurethane material of the sole, so that this material completely surrounds the fibers and fixes their directions relative to one another, as can be seen more clearly from FIG. 3.
  • the fibers in the layer 4 are arranged randomly in relation to one another, so that they do not form an arranged fibrous structure like a woven fabric or equivalent.
  • the fibers can be felted together. Felting means that the fibers become hooked together and attached to one another without forming a regular pattern. Such a felted or tangled layer can, even if it is thin, be handled as a unit during the procedure for manufacturing the sole. Other methods of holding the fibers together without them being structured but which facilitate their handling can also be used. The important feature is that the fibers are in “chaos”, that is to say in an entirely unarranged state.
  • the fibers can, for example, be felted together to form layers with a weight per unit area of roughly 500 g/m2. During manufacture of the sole, it is then suitable for two layers to be arranged one on another. Depending on the thickness, it is also possible to use a single layer or more than two layers.
  • fibers made of a high-molecular polyethylene material which is marketed under the tradename DYNEEMA®.
  • Other fibrous materials with equivalent properties can also be used.
  • the invention also includes the use of new fibers with improved values which may be developed in the future.
  • the invention aims primarily to provide a means of protection against penetrating objects of the type indicated above, such as nails, pointed weapons and the like, which have a relatively low speed in comparison with projectiles, such as bullets.
  • the invention has been described above in connection with the protective shoe shown in the figures, in which a protective layer is molded integrally in the outsole.
  • the protective layer can also be molded integrally in a loose insole or in the fixed insole.
  • the protective layer according to the invention is also suitable for producing, for example, flexible protective jackets and protective trousers which provide protection against, for example, stabbing with a knife.
  • flexible protective layer is of the greatest importance. This is achieved owing to the fact that a protective layer according to the invention can be made thin and contains flexible fibers.
  • the binder is then selected depending on application and can consist of, apart from polyurethane, other polymeric elastomers.
