Abstract
This invention describes a 3-layer insulation material comprising a first fabric layer, a second fabric layer and a third fluted intermediate fabric layer between the first and the second fabric layers, the fluted intermediate fabric layer being attached alternately to the first and the second fabric layer with longitudinal seams forming longitudinal channels for the insulation material having individual insulation material bundle inside each longitudinal channel. Also disclosed are a method and an arrangement for producing the same.
Claims4
The 3-layer insulation material of claim 1, wherein the third fluted intermediate fabric layer is made infrared absorbent by applying the surface by infrared absorber.
A method for producing a 3-layer insulation material comprising the steps of:
- introducing a first fabric layer, a second fabric layer and a third fluted intermediate fabric layer between the first and the second fabric layers, the first fabric layer and the second fabric layer being infrared radiation transparent fabric and the third fluted intermediate fabric layer being infrared radiation absorbing fabric, and
- attaching the third fluted intermediate fabric layer alternately to the first fabric layer and the second fabric layer for forming plurality of longitudinal bundle channels,
- wherein
- the first fabric layer and the second fabric layer are attached to the third fluted intermediate fabric layer by laser welding.
