<p>The present invention relates to a fiber insulation material for the manufacture of a non-woven fiber batt comprising primary fiber components of a portion of 50% to 90% cellulose fibers; 2% to 20% synthetic fibers, said synthetic fibers being crimped fibers having a length between 12 to 75 mm; and 2% to 20% bi-component fibers comprising a core and an outer sheathing, said outer sheathing having a lower melting point than the core. Hereby, an inexpensive and voluminous fiber product is achieved having good spring elastic properties as well as good sound and heat insulating properties.</p> |
