Abstract: The invention relates to a method for producing flexible or elastic wood fiber insulating material products, having the following steps: -providing wood fibers which have been produced in a refiner. -providing multicomponent fibers with an inner and an outer component, said outer component melting or fusing at a melting temperature at which the inner component does not melt or fuse or has not yet melted or fused. -providing a mixture of wood fibers and multicomponent fibers. -heating the mixture to a temperature at which the outer component melts or fuses, and—connecting the multicomponent fibers together and to the wood fibers while cooling the mixture, wherein hardwood fiber bundles, in particular beechwood fiber bundles, are used as the wood fibers, and biodegradable multicomponent fibers are used as the multicomponent fibers.

Abstract: The invention relates to a method for production of an auto-adhesively bonded, porous, pressure-resistant molding made from comminuted lignocellulosic fibrous materials that are processed at temperatures between 120° C. and 180° C. and a pressure between 2 bar and 8 bar to yield a fiber suspension that is subsequently filled into a mold or applied to a carrier and dried without the addition of a synthetic binder.
