Definitions

  • the present invention relates to a sheathed wire of natural appearance.
  • the present invention also relates to a textile produced from a sheathed yarn of natural appearance.
  • the present invention also relates to a method of manufacturing a sheathed wire of natural appearance.
  • thermoplastic materials which combine both excellent mechanical performance and a natural appearance detectable by sight and by touch.
  • environmental requirements are rarely met with regard to the use of materials of natural origin and the ability to be recycled to obtain products based on threads intended for all uses, for example textiles. This is particularly the case for textiles with outdoor applications, subject to weather and sun, and for textiles that must resist fire.
  • thermoplastic material comprising fibers of plant origin, intended to improve the aspect of perception by the consumer, is corrected.
  • a first problem posed is to develop a new type of sheathed wire having excellent mechanical properties and excellent properties of use in fire resistance, weather resistance, sun resistance, etc.
  • a second problem posed is to obtain a wire having an external appearance generating particularly pleasant visual, tactile and olfactory sensations.
  • a third first problem posed is to produce a wire incorporating materials of natural origin.
  • a fourth problem posed is to develop an efficient process for manufacturing a wire based on thermoplastic materials.
  • a sheathed wire of natural appearance having a core wire and a sheath made of a thermoplastic material is characterized in that the thermoplastic material of the sheath comprises less than 20% by weight of staple fibers.
  • the yarn will have a particularly interesting external surface appearance.
  • the core thread can be a multifilament thread.
  • the core yarn can be a yarn of polyester, polyvinyl alcohol or polyamide.
  • the themioplastic material of the sheath can preferably be chosen, alone or as a mixture, from the group of polymers and copolymers comprising polyolefins, polyesters, polyamides, polyvinyl chlorides, polyvinyl alcohols, silicones as well as fluorinated polymers.
  • the quantity of fibers of the themioplastic material of the sheath can be between 1% and 15% by weight. Preferably, this amount can be between 4% and 12% by weight. Very preferably, this amount can be between 6% and 9% by weight.
  • the staple fibers can be chosen alone or as a mixture from the group comprising natural fibers and synthetic fibers.
  • the natural fibers can be hemp fibers.
  • the staple fibers can advantageously have an average length of between 10 ⁇ m and 500 ⁇ m. Preferably, this length can be substantially equal to 100 ⁇ m.
  • Staple fibers can have an average diameter between 3 ⁇ m and 100 ⁇ m. Preferably, this diameter can be substantially equal to 20 ⁇ m.
  • textiles are characterized in that they are made from the sheathed yarn as described above.
  • a method for producing a sheathed wire of natural appearance as described above comprises the step consisting in sheathing a core wire by extrusion by passing through a die, with a thermoplastic material comprising less than 20% by weight of staple fibers.
  • the themioplastic material comprising less than 20% by weight of fibers can advantageously be obtained by mixing one or more times of a themioplastic material not loaded with fibers with a masterbatch comprising from 5% to 80% by weight of fibers.
  • the masterbatch can preferably comprise between 20% and 70% by weight of fibers. And very preferably, the masterbatch can comprise between 40% and 60% by weight of fibers.
  • FIG. 1 shows an enlarged longitudinal view of a sheathed wire according to the prior art and a sheathed wire according to the invention
  • FIG. 2 shows a cross-sectional view taken with an optical microscope of the sheathed wire according to the invention.
  • FIG. 3 shows an enlarged top view of a textile made from sheathed son.
  • the core is covered by extrusion or coating with a layer of peripheral polymer material.
  • the photographs enlarged approximately 20 times in FIG. 1 show a comparison between a sheathed wire (1) according to the state of the art (placed on the left), represented by the document FR-2.617.205 and a sheathed wire (2) according to the current invention (placed on the right). Due to the presence of staple fibers, the outer surface of the wire (2) obtained by the method according to the invention has an irregular appearance and looks like twine. The average diameter can thus be less than 1 mm and vary between 0.6 mm and 0.9 mm. On the other hand, the external surface of the traditional sheathed wire (1) is smooth.
  • the core thread is a multifilament thread, high tenacity, that is to say having a tenacity of the order of at least 50 cN / tex.
  • the multiple filaments of the core are twisted or not, interlaced or not, assembled or not, textures or not, depending on the final sheathed yarn desired.
  • Figure 2 shows a cross section of the sheathed wire (2) taken under an optical microscope with an enlargement of approximately 150 times.
  • the sheathed wire (2) the multiple polyester filaments (3) of the core (4) appear in the center.
  • the sheath (6) based on PVC compound surrounds the core (4).
  • the sheath (6) incorporates the hemp fibers (7) embedded in the PVC.
  • the periphery of the sheath (6) is very irregular, giving the whole thread a natural feel.
  • the core and the sheath are produced directly by co-extrusion.
  • the sheath (6) is extruded around the core wire (4).
  • the sheath themioplastic polymer compositions also advantageously comprise additional adjuvants: at least one anti-UV agent, and / or at least one biocidal agent, and / or at least one mineral filler, and / or at least one pigment, and / or at least one flame retardant.
  • the flame retardant can be mineral flame retardants, such as, for example, antimony oxides, alumina trihydrate, zinc oxide or magnesium oxide.
  • the weight ratio between the core wire (4) and the sheath (6) depends both on the final applications envisaged and on the extusion or coating material available.
  • Such threads can be used in multiple applications, and in particular the manufacture of furniture, typically camping seats, car covers, floor and wall coverings, sun shades, luggage articles, protective fabrics and others.
  • Figure 3 shows an example of textile enlarged about 10 times, entirely made from yarns (2), with a 100% polyester core sheathed with a PVC and hemp fiber compound according to the invention, and heat-fixed. Textile includes yarn warp (8) horizontally and two weft threads vertically (9 and 11). Note that the wires have different colors.
  • a sheathed wire (2) according to the present invention is produced in the following manner.
  • a polyester yarn of 1100 dtex, sold by the company Rliodia under the name "Type 156”, is sheathed by extrusion by passing through a die.
  • the wire running speed is 300 m / min.
  • the extruded sheathing composition comprises: 7% hemp fibers;
