Definitions

  • the invention relates to a method of manufacturing felt pens plants from tows and the product obtained by this process and especially its use in thermal and / or sound insulation or in the field of packaging.
  • the seats and the fuel tanks of the first aircraft were natural fibers impregnated with some polymer, which acted as the binder.
  • plant-based fibers may be envisaged in many industrial fields, particularly automobiles.
  • thermosetting matrix such as an epoxy, vinylester or polyester resin.
  • the object of the present invention is to propose a method of manufacture of vegetable felts which overcomes the aforementioned drawbacks, particularly with regard to the manufacturing process.
  • Another object of the present invention is to propose the manufacture of 100% vegetable felts.
  • the tows used in the present invention are obtained using conventional methods of separating the woody part of the fiber in textile plants.
  • the fibers used according to the present invention are strongly loaded in anas, which allows to value many co-products more or less woody plants and to respect the imperatives environmental recycling.
  • cutting means the mechanical operation that consists of separate the textile fibers from the rest of the plant stem.
  • the felt obtained are 100% vegetable.
  • the fibers used in the process can be previously bleached by chemical treatment without affecting the process.
  • the tows in a first step, the tows to form a fibrous ground material. More precisely, in this step, we grind the tows into fluffy flakes.
  • cellulosic agricultural co-products and / or lignocellulosic can optionally be incorporated as a mixture, and thus the tows are ground to form a fibrous grind, possibly with other cellulosic and / or lignocellulosic co-products.
  • tows eg linen
  • tows can to be partially substituted, in varying proportions that can reach 95%, depending on the physicochemical, hydric and mechanical characteristics and desired thermal, by other tows, or more generally, by any other cellulosic and / or lignocellulosic plant mixture, including beet pulp.
  • the type of grinding can be adapted to the starting materials and the desired texture, producing felts that can be more or less ends according to the proportion of capitaous fractions and the type of grinding.
  • the tows are tows of flax.
  • Flax has the advantage of having good mechanical properties among other plant fibers (table below) and being easy to supply in France.
  • flax tow can be used, whether oleaginous linseed or flax fiber, whatever the varieties and regardless of the treatments undergone in culture and the degree of retting.
  • Retting means the microbial action intended to eliminate the pectic cement encapsulating cellulosic fibers in the bark of plants textiles, such as flax, and to isolate the latter in order to obtain the tow.
  • the bromates are brewed in a liquid medium.
  • brewing is carried out cold in an aqueous medium, and can be carried out manually or mechanically.
  • the brewing remains very short, of the order of the minute and the water is provided in sufficient quantity to totally soak the fiber, eliminating in this way a part of the water-soluble molecules.
  • the stirred fibrous ground material to heat treatment.
  • the heat treatment to which the fibrous ground material is subjected is carried out by microwaves.
  • the treatment time is adapted to the power of the microwave and its mode of operation, know continuously or discontinuously.
  • Microwave heating in a humid environment the advantage of speed, of lack of inertia, because the stops and the road are instantaneous, ease of use with a regulation of the easy power.
  • the molecular agitation within the mixture is sufficient to entangle the fibers while a fraction of the water is removed by evaporation, which favors the posterior drying of the product.
  • the stirred fibrous ground material is molded to form a felt. More precisely, after the microwave treatment, the wet fibrous mixture is cast in a hot mold and in particular pressed to remove most of the water. With the pressing, the fiber sample is reduced to about half of its original volume and a more or less compactness can be applied according to the texture desired.
  • the felt obtained is dried. More precisely, and according to one example, the drying of the fibers can be carried out in two steps, a first drying step with the fibers in the mold, and a second step with the demolded fibers. In other modes of realization, the drying can be carried out by microwave or by infrared or any suitable treatment.
  • Another object of the present invention relates to the product obtained by the process object of this patent.
  • This product namely a 100% vegetable felt, presents the advantage of being compatible with mineral materials, of being able to shaped at will during the process and retain its shape after drying.
  • the felts are completely recyclable in circuit closed for the production of new felts or for the production of compost, in the case of end-of-life markers.
  • the felts obtained by the present process can be made non-flammable.
  • the product obtained according to the process described in the present invention is used in thermal insulation and / or soundproofing, as well as in various furnishing accessories, in the automotive industry, toy and decoration industries, packaging, horticulture, etc.
