Claims10
A method for obtaining an insulation material from a semi-finished non-woven fabric, the method comprising:
- applying a polymer emulsion onto the semi-finished non-woven fabric in a dot pattern, wherein the polymer emulsion is selected from the group consisting of an acrylic, SBR, rubber polymers, EVA, VAE, HDPE and PU;
- scattering a thermoplastic powder or thermoset powder or an elastomer powder onto the polymer emulsion on the semi-finished non-woven fabric;
- vacuuming free powders of the thermoplastic or thermoset or elastomer powder from the polymer emulsion-applied semi-finished non-woven fabric;
- fixing spots of the thermoplastic or thermoset or elastomer powder onto the polymer emulsion-applied semi-finished non-woven fabric;
- passing and shaping a layer of the semi-finished non-woven fabric through a cold calendar;
- and
- winding the layer of the passed and shaped semi-finished non-woven fabric.
