Definitions
- the invention relates to a fiber composite made of fibers chemically or physically foamable polymers has and in which the fibers only after production of the Fiber composite are foamed, as well as the use of such a fiber composite and a method for the same Production.
- Polymer fibers are made by spinning or extruding manufactured and found mainly for the production of Sutures, textiles, but also with a variety technical goods use. They are usually too Fiber-bonded, such as woven, knitted or crocheted Scrim, processed, from which in turn textile materials for clothing, laundry or covering materials, Filter cloths, sieve cloths, packaging covers, laminations and the like. Furthermore are Fiber composites made from mixed fibers are known, e.g. made of 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.
- a large number of polymers can be passed through today Process spinning or extruding into fibers, whereby the Selection of the polymer tailored to the intended use becomes.
- the fibers after spinning or Equip extrusion with equipment This can be in a subsequent physical or chemical Treatment or coating of the surface exist.
- the surface is structured.
- the invention has for its object the positive To use properties of foamed fibers only there, where they are on the finished fiber composite or the one to be produced from it End product are needed.
- a fiber composite designed according to the invention draws is therefore characterized in that it consists of several layers consists of fibers, at least one of which is external Layer has blowing agent-free fibers, while the fibers containing blowing agent at least one other Layer only in specified areas of the fiber composite are foamed.
- composite materials can be made from textiles and create foamed structures, such as for upholstery materials with a textile Surface structure on a foamed carrier is desirable are.
- Preproducts or Manufacture end products only in those areas have foamed fibers in which the by the Foaming properties such as cushioning, Shock absorption ability, compressibility, insulation ability od.
- foamed fibers in which the by the Foaming properties such as cushioning, Shock absorption ability, compressibility, insulation ability od.
- Fiber composite e.g. in the form of a fabric, knitted fabric or knitted fabric or scrim.
- the fiber composite can, for example, be made of fibers with a Blowing agents contain polymers and fibers made from blowing agent-free Have polymers, the latter especially can consist of such polymers which the desired Properties of the end product in the non-foamed Determine areas. It can be particularly also natural fibers, metal or carbon fibers act for technical purposes of the fiber composite are suitable.
- the fiber composite according to the invention can also at least another intermediate layer made of non-foamed fibers have, as a stabilizing insert with if necessary increased tensile strength.
- the fiber composite according to the invention is, for example, as Textile material can be used for special clothing.
- Such a fiber composite can Use the production of partially foamed moldings.
- Such Shaped bodies can be used as upholstery for seating or reclining furniture, Car seats, interior trim parts of motor vehicles etc. are used.
- the polymers and foaming techniques known today allow the production of closed or open cells Structures. These options can also with Fiber composite according to the invention can be used, in particular you will provide closed cell structures, if the fiber composite should be water-repellent. This water-repellent property is further supported by that the fibers in the foamed areas lie close together, while the fiber composite in the other areas and in the blowing agent-free fiber layers the traditional property of those who made it Has fibers. Diffusion-tight and Realize areas open to diffusion.
- fibers that are at least partially from one diffusion-tight polymer consist of a bound or loose composite, e.g. a fabric, knitted fabric, knitted fabric or clutches, merged and is then in the specified Areas of the fiber composite comprising these fibers a fluid, e.g. a liquid or a gas, introduced by pressure diffusion and the penetrated Fluid expands due to the sudden reduction in pressure.
- a fluid e.g. a liquid or a gas
