<p>The invention relates to a process for the production of mouldings, in which a fibrous material is mixed with an adhesive and held under pressure in a mould until the adhesive has set. The process is characterised in that the fibrous material employed comprises essentially cut, chopped and/or torn synthetic monofilaments which provide the moulding with hardness and rigidity at the same time as a large-pore free volume, and in that the proportion of adhesive in the finished moulding is less than 10 % by weight, based on the moulding. The invention also claims mouldings comprising short monofilaments which are obtainable by the above process. These mouldings are characterised in that monofilament support material gives the moulding hardness and rigidity at the same time as a large-pore free volume, and in that a proportion of adhesive of less than 10 % in the finished moulding essentially provides cohesion and elastic properties. The process allows monofilament scrap to be recycled.</p> |
