Embodiment Construction
[0042] As already seen, resin flooring includes trim boards, covering boards, particle-based (MDF (medium density fibre), HDF (high density fibre), etc.) panels and covering boards. The present invention relates to an improvement in the processing of paper used as a printing base (decorative sheet) for resin paper, the overlay sheet being applied by a converter if necessary.
[0043]To this end, support papers based on slightly refined fibers comprising a mixture of 50-20% by weight of long-fiber pulp (softwood) and 50-80% by weight of short-fiber pulp (hardwood) are first produced.
[0044] By long fibers is meant fibers of 3-5 mm, from trees such as pine, spruce, radiata pine or Douglas fir. Short fiber pulp of about 1-2 mm comes from eg eucalyptus, acacia, maple, birch or chestnut.
[0045] The specific components of this mixture are chosen to form a support which is particularly suitable for impregnating its core with the resin to be coated on the paper surface.
