Abstract
A two-dimensional material for the medical wound area treatment is disclosed. A non-woven fabric consists of resorbable polymer filaments and collagen particles which have a particle size I>80 μm and are disposed on and/or in the non-woven fabric.
Claims19
A method for producing a two-dimensional material for medical wound area treatment, comprising the steps of:
- providing a non-woven fabric made of resorbable polymer filaments;
- providing collagen particles having a particle size I>80 μm;
- scattering the collagen particles onto the non-woven fabric, the collagen particles which are then arranged on and/or in the non-woven fabric;
- and
- subsequently calendering the non-woven fabric with the collagen particles.

A method for producing a dry two-dimensional material for medical wound area treatment, comprising the steps of:
- providing a non-woven fabric made of resorbable polymer filaments;
- providing collagen particles having a particle size I>80 μm;
- suspending the collagen particles in an aqueous solution forming a collagen suspension;
- subsequently applying the collagen suspension to the non-woven fabric;
- and
- subsequently drying the non-woven fabric with the collagen suspension.
