Abstract
The invention relates to a method for forming a hydraulically bound web. A homogeneous mixture of wood pulp and synthetic fibers is blown on a forming surface. The web has a mixture of at least 70% wood pulp by weight of the mixture. The web is subjected to hydraulic bonding to form a stable fabric. The web is further heated to a temperature to cause partial melting of the synthetic fibers and further bonding of the fabric.
