Definitions

  • the present invention relates to a material for personal clothing which is suitable for resisting piercing by hypodermic needle points and other pointed or sharp objects, and to clothing objects such as gloves and vests made of or provided with such a material.
  • a material for personal clothing which is suitable for resisting piercing by hypodermic needle points and other pointed or sharp objects
  • clothing objects such as gloves and vests made of or provided with such a material.
  • the waste may contain hypodermic needles which may transfer infection when by accident they pierce the hand, and it is evident that at least protection gloves should be used for lowering the risk.
  • the invention is based on the finding that for a completely different purpose there has been developed a thin layer material consisting of a very dense metal wire net which is intended for use as filter material, the net being semi-inertly air permeable, and that this net in spite of its pronounced thinness of about 0.2 mm has a very great resistance to piercing by hypodermic needles. Because of its thinness the material is easily bendable or at least sufficiently bendable for forming part of a work glove or a vest without making this so heavy or stiff that it is unusable in practice.
  • the metal web may being usable as an intermediate layer between an outer material layer which has a protecting and friction-generating surface, while the metal web material has a low degree of surface friction, and an inner covering layer of an appropriate, desirable softness which is of course absent in the metal web.
  • the metal web is bendable, but it is not the least stretchable, and for this reason a glove provided at both its outer and inner side with the metal net would be very rigid, which is definitely not suitable for such a glove.
  • the special barrier layer need only be provided at the inner side of the glove, as there is normally no strong pressure action against the outer side of the glove, and thereby the outer side may well consist of a conventional protecting, but so reasonably stretchable material that in spite of the presence of the bendable and unstretchable metal web layer at its inner side, the glove as a whole is easily bendable and thereby usable in practice.
  • the finger portions of the glove it is not sufficient to deal with only an inner and an outer side, as the side portions of the finger portions come into consideration by being in the danger zone with regards to piercing risk.
  • the side portions of the finger portions come into consideration by being in the danger zone with regards to piercing risk.
  • the bendable, but otherwise shape stable metal web does not further a good bendability, but it is seen that the fingers are easily bendable anyway, because the edgeways placed metal web is easily foldable for allowing such a bending.
  • the upper side of the outer fingertips may come into the said danger zone, and the glove may very well have these portions covered with reinforced layer portions which will not in general reduce the bendability of the glove.
  • the thin net material Used in clothing objects the thin net material will be highly pierceproof, and moreover be advantageous by its easy bendability and almost negligible weight. It is certain that part of the explanation of the pierceproof effect is the total unstretchability of the material, and of course this characteristic is not too appropriate in connection with different types of clothing objects; however, as the material is very light and very smooth there are good possibilities of placing it in partially overlapping areas in such a manner that the layers may slide on each other in the space between the adjacent outer cover layers, whereby it is possible anyway to make clothing objects which provide a good degree of freedom of movement.
  • the outside of the metal web be provided with a leather-like material, but it will be possible to effect a differentiation of the material choice, here also the choice of metal web quality, for optimizing the clothing object as a whole.
  • Different areas of the body may need different degrees of protection, and the clothing object may be designed in a differentiated manner taking into consideration both these needs, e.g. by area-wise insertion of several layers of the material, and other requirements as to the bendability and softness of the single areas.
  • the leather may be used with different degrees of thickness and be tanned more or less soft as needed.
  • knife stab protection may be chosen a slightly heavier metal web as there should here be anticipated a higher and even blow-like piercing pressure.
  • micro filter web The said metal web material for filter use occurs in practice with the designation "micro filter web". What is concerned here is a stainless wire net with warp threads of about 0.04 mm placed with a mutual distance of a few millimeters and with extremely closely placed weft threads of about 0.03 mm, indicated by the expression 0.04/0.03. It is believed that qualities in the scope 0.025/0.02 - 0.07/0.05 will satisfy most requirements in the present connection. It can be referred that the corresponding scope of variation for the absolute filter fineness is 6-25 micron and for the nominal filter fineness it is 1-15 micron, but it should be considered that this is not representative of a permeability as relevant here. The material can only be penetrated by light to a very low degree.
  • the invention is not limited to the use of exactly this material.
  • the need for "hypodermic needle proof” and stab proof clothing, respectively, is so great that there may be grounds for a production of materials which are optimized directly to various purposes 0f use, where it is not necessarily decisive that the threads be placed so extremely close to each other that not even the tip of a pin may get a 'foothold' in the web meshes.
  • hypodermic needles it is just very important to ensure that the threads be difficult to cut, though they should still be placed very closely together in order not to allow the needle to pass by simple expansion of the mesh.
  • the protection effect is increased considerably when the web is covered by a layer of leather or suede.
  • the leather layer may be replaced by antoher material, which should be correspondingly tough and fibrous, e.g. closely-woven canvas.
  • the said metal web material should not be so extremely pierceproof that it does not even allow piercing by a sewing machine needle applied with force as, at least in connection with gloves, it is desirable that the material can be cut in the same manner as the outer and inner side layers and be joined with these for welt sewing of the glove in an otherwise conventional manner.
  • the sewing machine needle will stick its way through the net material with a strong lateral displacement of the mesh threads, and therefore it will not be deformed by the piercing as would an hypodermic needle point.
  • the metal web insert may well be present in seam areas of the glove, where it perfectly well can be penetrated by a really pointed sewing machine needle.
