Abstract (en)

[origin: EP1046737A1] A fibrous felt is prepared using a thermoplastic polymer powder binder comprising a vinylester and/or a (meth)acrylic acid ester. A fibrous felt (I) is prepared by means of an air-lay process, whereby the fibers and the binding agent powder are put down an air stream. The process comprises (A) laying a fibrous felt or fiber to a weight of 10-50 g/m<2> (B) fibers and a thermoplastic polymer powder, based on vinylester and/or (meth)-acrylic acid esters are applied separately or as a mixture in an stream at 10-300 g/m<2> with optional repeating of step (B) until the desired fiber weight is achieved. (C) the fibrous material is consolidated at 80-260 degrees C and optionally at up to 100 bar.
