Definitions

  • the invention relates to a thread for the production of a technical fabric, knitted fabric or the like, based on carbon, glass, aramid, ceramic fibers or the like, and to the method for processing such a fabric or knitted fabric or the like.
  • the area of application is primarily in the container construction and body parts sectors. With good deformation properties, however, there is a relatively low fiber volume content, that is, the product is heavy in weight with relatively low strength values.
  • a process known under the catchphrase "GMT" concerns the basic idea: glass fiber mat with thermoplastic matrix. Here short glass fibers or filaments are worked into a thermoplastic mass. When heat is applied, this material can be deformed and processed into components by pressing at the same time. Therefore, there is also an application in the deep-drawing process. There are also unidirectional fabrics. This means that the reinforcement fibers are only laid in one direction (anisotropic reinforcement structure).
  • Knitted fabrics bring improvement here, but with the disadvantage of poorer utilization of the fiber-specific properties and, as already mentioned, multi-layer fabrics.
  • the undulation of the fiber strands that occurs during the deformation of the reinforcement materials leads to a partial reduction in the strength or rigidity of the composite body. This fact must be taken into account when dimensioning the use of materials, ie this deficiency must be compensated for by using more material, but this leads to higher costs, component thicknesses and additional weight.
  • the object of the invention is to form a thread formed from the above-mentioned high-performance materials without any technical disadvantages in terms of weaving or strength so that the formability of a fabric formed therefrom is considerably improved.
  • a thread having an optimal structure with regard to the deformability of a fabric formed from it is created.
  • the aforementioned reinforcement materials can still be used.
  • the procedure is such that the fibers mentioned are combined as staple fibers with a dissolvable outline thread.
  • corresponding staple fibers have the advantage that they can be lengthened if necessary.
  • an average stack length of 40-80 mm has proven to be favorable.
  • Such a stack length also has negligible losses in stability on the fabric compared to continuous fibers.
  • the knitted or woven threads are given a good bond due to the undulating and crossing courses.
  • the threads take a completely straight course from the start, the wrapping thread keeping this staggered thread bundle bundled in a helical wrap.
  • the winding is relatively loose, so that the axial mobility of the thread chop is not affected, so that, as already indicated, such a yarn also has sufficient strength for the weaving process.
  • the thread is only a small part of the total weight because it is made of very fine material. In certain cases, the proportion of the winding thread should be as low as possible, with optimal consideration of 2 - 5%.
  • the basic structure of the thread then remains by dissolving the winding thread or yarns alone in the best possible condition. With regard to this dissolution of the winding thread, it is proposed to effect it chemically.
  • the winding thread can consist, for example, of acetate fibers and can be dissolved in an appropriately adjusted acetone bath. Another possibility is that the winding thread is thermally dissolvable. If, for example, viscose threads are used as wrapping threads, they are destroyed by scratch treatment at 200 - 300 ° C. The ash residues are then knocked out. Another way of eliminating the winding thread is that it is formed from thermoplastic material, which is also used as a matrix material. A fabric based on technical fibers such as coal, glass, aramid, ceramic is then characterized in that the fibers are processed as staple fibers wrapped with a winding thread.
  • a knitted fabric based on technical fibers such as coal, glass, aramid, ceramic is characterized in that the fibers are processed as staple fibers wrapped with a winding thread.
  • a favorable method for processing a woven fabric, knitted fabric or the like on the basis of carbon, glass, aramid, ceramic fibers is that the winding thread for the production of a structured component is locally dissolved. It is advantageous that the wrapping thread consists of the same material, namely thermoplastic, as the matrix material. Here, the winding thread is dissolved in a complete opening in the substance that determines the shape of the component.
  • the thread 1 shown consists of a multiplicity of staple fibers 2 oriented identically or in parallel.
  • the correspondingly staggered, overlapping fiber structure is held together by a thread 3.
  • the corresponding wrap pressure is low, so that the displaceability of the staple fibers 2 is not impaired.
  • the staple fibers 2 consist of carbon, glass, aramid or ceramic.
  • the staple fibers 2, which are cut to length, for example, from an endless thread sheet, have a length of approximately 40-80 mm.
  • the winding thread 3 can be detached or destroyed. It is expedient to destroy it after creating a fabric G.
  • the weaving measures are practically the usual ones. It can be a plain, twill or atlas weave. Modifications of this are also conceivable and should be chosen according to the intended goal. In addition, a multi-layer fabric can also be created.
  • the row-like arrangement of the staple fibers 2 in an overlapping arrangement proves to be advantageous wherever there are high demands on the deformability of the woven fabric G or knitted fabric G.
  • the wrapping thread 3, which otherwise gives the fabric G sufficient strength in the weaving process is dissolved. Even in the dissolved state, there is still such a stable tissue composite that the tissue is easy to handle, that is, for example, it can be introduced into a shape (not shown).
  • the lengthening of the thread composite of the staple fiber threads 1 is illustrated in FIG. 7.
  • the weft threads a aimed at the viewer take up their usual tissue adjacent position at the edge of the deep-drawing T, spaced apart by the dimension y, while due to the deep-drawing process the weft threads a which are arranged vertically somewhat offset one above the other have a larger thread spacing, dimension z.
  • the warp threads b on the other hand, one of which is shown, have a continuous axial elongation by shifting the adjacent staple fibers 2 relative to one another, as seen in the thread extension direction.
  • the direct train length supply which is present in the flat surface of the fabric G near the edge, is also used here.
  • the winding thread 3 can be dissolved chemically. This happens e.g. B. in the stenter at a temperature of 160 - 180 ° C, in a chemical solution, for example, when desizing the fabric G.
  • the dissolution takes place in an acetone bath.
  • the thermal dissolution of the wrapping thread for example when using a viscose thread, is carried out by heat treatment at 200 - 300 ° C. Then the ash residues are knocked out.
  • a “dissolution” of a different kind consists in the fact that, due to a special choice of material, the wrapping thread 3, which is also made of thermoplastic material, merges into the hot matrix material supplied during molding, so that after thermal destabilization, which does not extend to ashing, the melted thread pieces are used in terms of material .
  • recyclable base material can be used, so that at least the fibers of the technical reinforcement fabric are retained through the recovery that is possible today.
  • the thread 1 constructed according to the invention and realized on the basis of the technical fibers mentioned can, as already indicated, be used instead of producing a knitted fabric G instead of the fabric G.
  • a component B (so-called organic sheet) on the basis of a multi-layer fabric, with which extend between the layers the filler threads, the multi-layer fabric also consisting of a technical yarn such as carbon, glass, aramid, ceramic fibers and the filler thread introduced as a weft thread being a group of threads based on polypropylene or polyamide, and wherein the multi-layer fabric is known per se Hardened way hardened.
  • a technical yarn such as carbon, glass, aramid, ceramic fibers
  • the filler thread introduced as a weft thread being a group of threads based on polypropylene or polyamide
