Definitions

  • the present invention relates to a wire based mica, i.e. a wire made up of at least 50% of mica, and extends to a spinning process allowing to get such a thread.
  • the invention extends in a complementary manner the use of such a product for all uses conventional yarn transformation, such as weaving, braiding, etc., in order to obtain essentially industrial products.
  • mica belongs to the class of non-fibrous products. Spinning being defined as all fiber processing operations yarn textiles, mica is therefore not suitable, principle, to spinning operations.
  • glass fibers including diameter is less than 3 ⁇ m and which are fibrillated are considered suspicious of being potentially dangerous to health.
  • Mica particles have of course already been incorporated in very small proportion in products filaments such as knitting wool. The goal was in this case to create optical, aesthetic and decorative.
  • the invention aims to provide a product new, which avoids the disadvantages described state-of-the-art products.
  • the invention relates essentially to a mica-based product, and more specifically based on mica paper, in the form of a wire.
  • mica-based means that the product contains at least 40%, and preferably at least 50%, by weight of mica.
  • Mica is an aluminosilicate type phlogopite, muscovite or synthetic, or may be consisting of a mixture of these different compounds.
  • mica paper The non-fibrous nature of mica opposing the direct production of a spinning, according to the invention that the mica is advantageously used in the form of a "mica paper".
  • the notion of "mica paper” is good known, and means that mica, which is a natural product or synthetic is first put in the form of glitter and then transformed by papermaking techniques to form leaves. So it's not chemically cellulose-based paper.
  • the product obtained can be cut under form of continuous ribbons.
  • the amount of reinforcement used can be very variable.
  • the joining of mica paper and reinforcement, either in the case of direct incorporation of this reinforcement in the mass of mica, either during the stratification, can be increased by the presence of a adhesive or a resin, in particular of the silicone type. Comes then the actual spinning operation, which is to twist this ribbon to the desired title value so to get a single wire.
  • This single wire can then be transformed by all the classic techniques of the industry textile. It can for example be twisted with another thread of another nature or be implemented directly, either to form braids (strand braids, flat braids, etc.), either to form a fabric or a mesh product, according to classic textile techniques.
  • Textile products obtained from this wire are suitable for a large number of industrial uses, allowing to take advantage of the intrinsic qualities of mica and in particular its electrical insulating properties and thermal as well as its fire resistance.
  • the technique of the invention provides a new product with intrinsically large application possibilities, in particular application industrial.
  • Such a wire lends itself to operations such as sizing and also dyeing using dyes or pigments.
  • the invention extends therefore to all applications of the wire obtained involving its transformation according to textile techniques known from one skilled in the art.
  • Mica being a non-fibrous mineral product and not harmful, is a potentially less product unsafe for food than those commonly used according to the state of the art, in particular asbestos.
  • a ribbon 10 suitable for spinning a ribbon is prepared having a width of approximately 5 mm consisting of a mica 1 paper of 75 or 120 g / m 2 adhesive coated with a silicone resin (15 to 20% by weight) on a glass cloth 2.
  • the mica constitutes minus 50% by weight.
  • This mica is treated in a conventional way in spinning until obtaining a thread of a title of:
