Definitions
- the invention relates to a fiber composite that has fibers made of chemically or physically foamable polymers, and to the use of such a fiber composite and method for its production.
- Polymer fibers are produced by spinning or extrusion and are mainly used for the production of sutures, textiles, but also for a variety of technical goods. They are generally processed into fiber composites, such as fabrics, knitted fabrics, knitted fabrics or scrims, from which in turn textile materials for clothing, laundry or covering materials, filter cloths, screen fabrics, packaging envelopes, laminations and the like are produced. Furthermore are
- Fiber composites made from mixed fibers are known, e.g. from polymer and natural fibers in textile technology or from polymer fibers on the one hand and metal, carbon or mineral fibers on the other hand for technical purposes.
- the surface is structured to create plump fibers.
- the invention is based on the object of using the positive properties of foamed fibers only where they are required on the finished fiber composite or the end product to be produced therefrom.
- a fiber composite designed according to the invention is therefore characterized in that the fibers of the fiber composite are only foamed after their production and only in predetermined areas of the fiber composite.
- preliminary products or end products can be produced which have foamed fibers only in those areas in which the properties produced by the foaming, such as cushioning effect, shock absorption capacity, compressibility, insulation capacity or the like , are desired, but in all other areas have properties such as those of a conventional fiber composite, for example in the form of a woven fabric, knitted fabric or knitted fabric or scrim.
- the fiber composite can comprise, for example, fibers made of polymers mixed with a blowing agent and fibers made of blowing agent-free polymers, the latter mainly consisting of those polymers which determine the desired properties of the end product in the non-foamed areas.
- a blowing agent and fibers made of blowing agent-free polymers, the latter mainly consisting of those polymers which determine the desired properties of the end product in the non-foamed areas.
- it can also be natural fibers, metal or carbon fibers that are suitable for technical purposes of the fiber composite.
- the fiber composite can consist of several layers of fibers, of which at least one outer layer has fibers free from blowing agent, while the fibers containing blowing agent are foamed at least one further layer.
- material composites can be produced from textile and foamed structures, as is desirable, for example, in the case of upholstery materials with a textile surface structure on a foamed carrier.
- Such a fiber composite can at least also have a further intermediate layer made of non-foamed fibers, which acts as a stabilizing insert with possibly increased tensile strength.
- the fiber composite according to the invention can be used, for example, as a textile material for special items of clothing.
- Protective work clothing, To name sports and winter sports clothing in that the fibers of the fiber composite are foamed in those areas of the item of clothing where cushioning and / or insulating properties are desired. These areas can be foamed either on the cut for the item of clothing or on the finished item of clothing by local chemical or physical treatment.
- Such a fiber composite can be used to produce partially foamed molded articles.
- Such moldings can be used as upholstered bodies in seating or reclining furniture, car seats, interior trim parts of motor vehicles, etc.
- closed-cell structures will be provided if the fiber composite is to be water-repellent. This water-repellent property is further supported by the fact that the fibers lie close together in the foamed areas, while the fiber composite has the conventional property of the fibers forming it in the other areas. In this way, diffusion-tight and diffusion-open areas can be realized.
- fibers which at least partially consist of physically or chemically foamable polymers are combined to form a bonded or loose composite, for example a woven, knitted fabric, knitted fabric or scrim, and the fiber composite obtained is chemically or physically subdivided in predetermined areas Foaming the polymer fibers in these areas.
- the fiber composite comprising these fibers is foamed in the specified areas by thermal energy. This can preferably be done by means of microwave energy, which on the one hand can be precisely metered and, on the other hand, above all can be localized precisely.
- fibers made of a non-diffusion-tight polymer can also be used, in which case a fluid, e.g. a liquid or a gas, introduced by pressure diffusion and the penetrated fluid is expanded by abrupt reduction of the pressure.
- a fluid e.g. a liquid or a gas
- This method has the advantage that no residual chemicals remain in the fiber and the polymer has the same chemical properties in the foamed and non-foamed areas.
