Definitions

  • This invention concerns a textile structure suitable for use in footwear, particularly safety footwear, which is required to have a high level of resistance to penetration by sharp objects such as nails and the like, especially through the sole.
  • the main object of this invention is to provide a protective textile structure to be used in footwear, particularly shoe soles, which structure offers high resistance to piercing and penetration by sharp and pointed objects, while having limited thickness and weight, adequate flexibility and reduced cost.
  • a further object of this invention is to provide a perforation-resistant textile structure that is also antistatic and/or resistant to high temperatures.
  • FIG. 1 is a schematic illustration of a first textile structure in conformity with the invention
  • FIG. 2 shows the polyester fabric used in the structure of FIG. 1 ;
  • FIG. 3 and 4 illustrate, respectively, the profile of the warp and weft of the fabric in FIG. 2 ;
  • FIG. 5 is a schematic illustration of a second textile structure in conformity with the invention.
  • a textile structure 10 , 10 ′ resistant to perforation in conformity with the invention basically consists of a number of layers 12 , 14 , 12 ′, 14 ′ of woven fabrics bonded together by means of a thermoplastic film.
  • the structure consists of one or more layers 12 , 12 ′ of woven aramidic fibers and one or more layers of high tenacity non-aramidic fibers (for example, polyamide, polyester, polyolefin, liquid crystal fibers) woven into a fabric structure.
  • Each separate layer of fabric has, preferably on the right side, a treated surface 16 coated with a polyurethane and/or acrylic resin reinforced with powders of hard, abrasive substances, preferably micronized ceramic materials in the form of silicates, e.g. of aluminum.
  • the layers of aramidic fibers can be individually alternated with layers of fabric in non-aramidic fibers.
  • a first textile structure resistant to perforation consists of a multilayer structure 10 including a layer 12 of a woven fabric in aramidic fibers and, stacked on this layer 12 , three layers 14 of a woven fabric in high tenacity polyester fiber.
  • the layers are bonded together by means of a thermoplastic film. At least one side of each layer has been provided with a surface ceramic treatment 16 .
  • the layers of fabric 12 , 14 are treated on the right side of the surface, the layer of aramidic fabric 12 and the adjacent layer 14 of polyester fabric with the treated surface 16 being in contact, the remaining layers of polyester fabric having the treated surface in contact with the untreated surface of the adjacent layer. In this way, both outer surfaces of the multilayer structure 10 are untreated. It is also advantageous to use the structure described above inside the soles of footwear with the layer in aramidic fibers on the tread side.
  • a structure produced in conformity with this invention has high mechanical resistance to perforation by pointed metal objects and impedes their progress through the layers of fabric.
  • this structure is advantageously characterized by the fact of being composed in a proportion that does not exceed about 15% by weight—of the total weight of the textile fibers used—of aramidic fibers, with the remaining part in high tenacity polyester fibers.
  • the fabric produced in this way has a finished weight of 340 ⁇ 350 ⁇ 5% gr/sq.mt. with a composition by weight of approximately 80% Kevlar ®, 10% polyurethane, 5% acrylic, 5% aluminum silicate.
  • the fabric produced in this way has a finished weight of 690 ⁇ 720 ⁇ 5% gr/sq.mt. with a composition by weight of approximately 86% polyester fibers, 7% polyurethane, 3.5% acrylic, 3.5% aluminum silicate.
  • the weaves used make it possible to produce fabrics with very tightly woven yarns, making their structure highly cohesive to provide by their very construction a good resistance to penetration, while maintaining a high degree of flexibility.
  • the compound weave used for the fabric in polyester fiber has been found to be particularly effective in the production of the multilayer structure 10 .
  • the bonding between the layers of fabric is obtained by hot calandering with the insertion of a thermoplastic film (polyolefin and/or polyurethane and/or polyester) between the layers of the structure; processing the combination with heat causes the bonding by merger of the ceramic material both with the thermoplastic film and with the surface layer of the adjacent fabric layer so as to obtain a single unit with a total thickness of not more than 3 mm and limited weight.
  • a thermoplastic film polyolefin and/or polyurethane and/or polyester
  • thermoplastic film made of polyester that is resistant to high temperatures
  • a structure can be obtained that is particularly suitable for footwear designed to be used in the presence of high heat sources.
  • the textile structure described above has a general composition of:
  • Tests carried out on the structure have proven its effective resistance to a force of at least 1100N exerted by a nail, as foreseen by standards pr EN ISO 20344, EN 344/92 and EN 12568/98.
  • the fabric in polyester fiber is in turn preferably produced with:
  • FIG. 5 A second example of a textile structure resistant to perforation in conformity with the invention is schematically illustrated in FIG. 5 .
  • the structure 10 ′ includes two bonded multilayers 120 , 140 , consisting of a first set of three stacked layers of a woven fabric 12 ′ in aramidic fibers provided with a surface ceramic treatment 16 and a second set of three stacked layers of a woven fabric 14 ′ in high tenacity polyamide provided with a surface ceramic treatment.
  • at least two adjacent layers 12 ′ of fabric in aramidic fibers or two adjacent layers of fabric 14 ′ in polyamide fibers or the two adjacent layers of the multilayer structures 120 , 140 have the treated surfaces 16 in contact with each other so that both the outer surfaces (top and bottom) of the structure 10 ′ are not treated.
  • the fabric produced in this way has a finished weight of about 300 gr/sq.mt. with a composition by weight of 80% of polyamide fibers, 10% polyurethane, 5% acrylic, 5% aluminum silicate.
  • a structure composed of three layers of fabric in aramidic fibers and three layers of fabric in high tenacity polyamide as described above, has a general composition of:
  • a textile structure capable of resisting penetration is also thermally insulating and can be used, in the traditional way, as a protective insert into soles which are applied to footwear by means of sewing or gluing.
  • This structure can also be used advantageously in the production of footwear the sole of which is directly made on the upper by injection molding.
  • this structure can constitute the insole, which is first sewn onto the upper after which the sole is injected. It has been ascertained, in fact, that the effective resistance to perforation and penetration of a nail, according to the terms of standard EN 344/92, does not prevent sewing the structure onto the upper, using needles of an appropriate type.
