Abstract
Improved wood fiber mat comprised of a mixture of thermo-mechanically processed wood fibers and synthetic fibers.
Claims26
A mat comprised of a thoroughly mixed blend of a predetermined percentage of wood fibers and a predetermined percentage of a thermoplastic material fiber, the wood fibers diameter being determined by a mesh screen, the wood fiber diameter ranging in size by using mesh screens between 8 mesh and 100 mesh, the melting temperature of said thermoplastic material fiber being below 400.degree. F., the thoroughly mixed blend of wood and thermoplastic fibers entangling to form a mat which has a porosity which permits vegetation to grow through the mat, and the wood and thermoplastic fibers being sized to allow the mat to become an integral part of the soil surface.
A mat comprising a water absorption and retention material layer, the layer consisting essentially of a thoroughly mixed blend of a predetermined percentage of wood fibers and a predetermined percentage of a thermoplastic material fiber, the wood fiber diameter being determined by a mesh screen, the wood fiber diameter ranging in size by using mesh screens between 8 mesh and 100 mesh, the melting temperature of said thermoplastic material fiber being below 400.degree. F., the thoroughly mixed blend of wood and thermoplastic fibers entangling to form a mat which has a porosity which permits vegetation to grow through the mat and the wood and thermoplastic fibers being sized to allow the mat to become an integral part of the soil surface.
