Definitions

  • the present invention relates to a reinforced thermostable hybrid wire.
  • the souls of these yarns are made from high strength and high modulus organic fibers, belonging to the family of PPTA (poly-para-phenylene terephthalamide) or other synthetic fibers with high mechanical properties (high strength, high modulus). .
  • PPTA poly-para-phenylene terephthalamide
  • These yarns have many applications in the field of the production of fabrics for the personal protection of people in different sectors such as civil protection, exposed sectors of industry, some military clothing, but also in civil areas, such as sport and leisure.
  • the yarns used for making the fabrics corresponding to the criteria of Table 1 are still yarns comprising two yarns or elementary strands. For example, Nm 36/2, 40/2 45/2, 50/2 ...
  • the document FR 2,611,749 discloses a hybrid wire according to the preamble of claim 1.
  • the object of the invention is to provide a reinforced heat-stable hybrid yarn, in which the reinforcement elements may be present in a smaller quantity than the previously known yarns, thus allowing the concentration of the reinforcing fibers to be determined, depending on the application. and to satisfy economic requirements, while allowing a conventional manufacture of this thread.
  • the yarn which it concerns comprises at least one strand made with a high modulus and high strength fiber yarn reinforcement core, based on organic or inorganic material and a cover of conventional long or short fibers at low modulus, the other strands being conventional fibers long or short low modulus, these other strands being arranged to provide protection of the cover or strand with reinforcement core.
  • this wire is constituted by a twisted wire in which the different strands are assembled by torsion.
  • the turns constituting the strands made of conventional fiber partially cover the turns made from the strand or strands including the reinforcement core, ensuring an improvement in abrasion resistance.
  • these other strands provide protection of the fibers of the core yarns against the action of ultraviolet rays and also allows to confine the fibrillation of high modulus and high strength materials inside. a yarn, which makes it possible to preserve the properties of correct appearance of the final fabric even after many washes or intensive use.
  • this thread comprises two strands, one of which comprises a reinforcing core and the other comprises conventional fibers long or short low modulus.
  • the weight concentration of the core yarn with respect to the total weight of the yarn is between 23 and 35%.
  • the fibers used for producing the reinforcing core have a modulus greater than 40 G Pa and a tensile strength greater than 13 cN / dtex.
  • the fibers used for producing the reinforcing core are chosen from polyparaphenylene terephthalamide (PPTA), polybenzyldoxazole (PBO) and polyethylene (PE) with a high molecular weight.
  • PPTA polyparaphenylene terephthalamide
  • PBO polybenzyldoxazole
  • PE polyethylene
  • the low-modulus fibers used for covering the reinforcing core and for producing the other strand or strands are chosen from meta-aramid and polyamide imide.
  • the low-modulus fibers used for covering the reinforcing core and for producing the other strand or strands consist of polymer fibers which are flame-retarded in the mass.
  • the low-modulus fibers used for covering the reinforcing core and for producing the other strand or strands are constituted by flame-retarded or non-flame-retarded plant fibers.
  • one of its components contains a fraction of conductive fibers or electrostatic dissipators.
  • thermostable fabric corresponding to the requirements of table (1) starting from a surface mass of 210 to 215 g / m2.
  • This yarn is a traditional yarn, obtained either long or short fibers, containing 100% thermostable fibers of the same nature as the fiber used for the cover of the first strand core yarn.
  • Nm 72 checking condition (9).
  • the yarn is a conventional yarn, obtained by a weight mixture of 50% of PVA fibers, and 50% of cotton fibers, made in cotton technique.
  • the yarn composition is therefore: - high strength fibers and high modulus 25% - PVA FR + Cotton fibers 75%
  • one of the advantages of this technology is to subtract the fibers of the core yarns from the action of UV very harmful in the case of use of PPTA fibers, PBO, therefore all fibers containing amide groups and aromatics.
  • This system also makes it possible to confine the fibrillation of the high modulus and high strength materials, inside one of the yarns constituting the complete yarn, and thus to preserve properties of correct aspects, even after very many washes or use. intensive
