Abstract

In a method for making a fibrous product from vegetable-based cellulosic fibers, an air flow (A) is used for forming a mat on an advancing forming platform (1). The mat is bonded by means of thermally bondable binder fibers, such as thermoplastic fibers intertwined with the cellulosic fibers such that, upon being brought to a binding state through the action of heat, said binder fibers bond the cellulosic fibers to each other in the mat. The thermally bondable binder fibers intertwined with cellulosic fibers are subjected to the action of heat already in air flow (A) carrying the fibers onto forming platform (1) by setting temperature of the air flow sufficiently high.
