Definitions
- the present invention relates to a reinforced thermostable hybrid wire.
- Fiber yarns, reinforced with a coaxial core, known from European Patent No. 0271 418, are obtained on modified spinning machines.
- the cores 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 resistance, high modulus) .
- PPTA poly-para-phenylene-terephthalamide
- These yarns find numerous applications in the field of the production of fabrics intended for the personal protection of persons operating in different sectors such as civil protection, exposed sectors of industry, certain military clothing, but also in civil fields, such as sport and leisure.
- a classification scale from 1 to 6 is interpreted as follows:
- the number 1 corresponds to the low requirements, the latter increasing continuously up to the number 6 which corresponds to very high requirements for the criterion considered, and meeting the vast majority of the standards in force.
- Table 2 highlights the characteristics of a fabric obtained from a yarn produced according to the patent cited above from the following materials
- Meta-aramid or Polyamide-imide performance Meta-aramid or Polyamide-imide performance:
- the yarns used for the production of fabrics corresponding to the criteria of table 1 are always yarns comprising two elementary yarns or strands. For example, Nm 36/2, 40/2 45/2, 50/2 ...
- the object of the invention is to provide a reinforced thermostable hybrid yarn, in which the reinforcing elements can be present in a quantity less than the previously known yarns, thus allowing a dosage of the concentration of reinforcing fibers, depending on the application. and to meet economic imperatives, while allowing conventional manufacture of this wire.
- the yarn it relates to comprises at least one strand made with a reinforcing core of high modulus and high strength fiber yarn, based on organic or inorganic material and a cover in conventional long or short fibers at low module, the other strands being in conventional long or short fibers with low module, these other strands being arranged to ensure the protection of the cover of the strand or strands with reinforcing core.
- the covering part of the fiber yarn constituting the core is very diluted and consequently very fragile to abrasion.
- this thread is constituted by a plied thread in which the different strands are assembled by twisting.
- the turns constituting the strands made of conventional fiber partially cover the turns made from the strand or strands including the reinforcing core, ensuring an improvement in abrasion resistance.
- these other strands provide protection of the fibers of the core yarns from the action of ultraviolet rays and also makes it possible to confine the fibrillation of materials with high modulus and high resistance inside.
- a spun yarn which allows properties of correct appearance of the final fabric to be preserved even after numerous washes or intensive use.
- this wire comprises two strands, one of which comprises a reinforcing core and the other of which comprises conventional long or short fibers with low modulus.
- the concentration by weight of the core yarn relative to the total weight of the yarn is between 23 and 35%.
- the reinforcing core yarn has a natural tendency to have a residual torque which unbalances the hybrid yarn.
- the conventional yarns constituting the other fraction of the hybrid yarn consist entirely of fibers with low modulus and low resistance. These fibers therefore have no residual torque capable of balancing the hybrid wire. To create this balance, it is necessary to maintain a gap between the unitary twists of the yarns composing the hybrid yarn. To this end, the hybrid wire meets a condition for balancing the twists according to the formula:
- the fibers used for producing the reinforcing core have a module greater than 40 G Pa and a breaking strength greater than 13 cN / dtex.
- the fibers used for the production of the reinforcing core are chosen from polyparaphenylene terephthalamide (PPTA), polybenzy dizoxazole (PBO) and polyethylene (PE) of high molecular weight.
- PPTA polyparaphenylene terephthalamide
- PBO polybenzy dizoxazole
- PE polyethylene
- the low modulus fibers used for covering the reinforcing core and for producing the other strand (s) are chosen from meta-aramid and polyamide imide.
- the low modulus fibers used for covering the reinforcing core and for producing the other strand (s) consist of polymeric flame-retardant fibers.
- the low-modulus fibers used for covering the reinforcing core and for producing the other strand (s) consist of vegetable fibers which are flame retarded or not.
- one of its components contains a fraction of conductive or dissipative fibers of electrostatic charges. If we analyze a twisted yarn with 2 strands, it is possible to imagine a construction of the following type, represented in the single figure of the attached schematic drawing:
- a first concrete example non-limiting for the scope of the invention will make it easier to understand the construction of the final yarn.
- thermostable fabric corresponding to the requirements of table (1) starting from a surface mass of 210 to 215 g / m2.
- Tt To obtain a sufficiently structured fabric, the title Tt must be
- the title of the core yarn is in this case:
- the covering fibers of this first core yarn consist of thermostable, "short” or “long” fibers which give a final result of
- This yarn is a conventional yarn, obtained either in long or short fibers, containing 100% thermostable fibers of the same kind as the fiber used for covering the core yarn of the first strand.
- the wire 6 thus formed can be diagrammed as follows:
- Ta title of the core yarn 100% high resistance fibers and high modulus Te: title of the cover of short or long thermostable fibers
- T t title of the second strand constituted by long or short thermostable fibers Nm45
- composition of this yarn is therefore:
- the title of the core yarn is in this case:
- the covering fibers of this first core yarn consist of 50% PVA fibers (polyvinyl alcohol) and 50% cotton fiber, which give a result of
- the yarn is a conventional yarn, obtained by a weight mixture of 50% PVA fibers, and 50% cotton fibers, produced in cotton technique.
- Ta, Te, Tt and T being defined as above, the final titer of the global yarn is as follows:
- the yarn composition is therefore: - high strength fibers and high modulus 25% - PVA FR fibers + Cotton 75%
- one of the advantages of this technology is to shield the fibers of the core yarns from the action of UV which is very harmful in the case of the use of PPTA, PBO fibers, therefore all fibers containing amide groups and aromatics.
- This system also makes it possible to confine the fibrillation of high modulus and high resistance materials, inside one of the yarns constituting the complete yarn, and thus to preserve properties of correct appearance, even after very numerous washes or use. intensive
