ABSTRACT:
A method for the production of a fibrous product containing curled fibers includes applying rectilinear bi-component fibers (17) to the upper side of a raw material sheet (2) before it is introduced into a defibrator (1). Immediately before the introduction a heating is effected. When the rectininear bi-component fibers (17) are introduced into defibrator (1), the beater bars (9) effect a curling effect to provide a raw material including curled bi-component fibers. Hereby it is possible to substantially reduce the manufacturing costs, however, having the effect of curled bi-component fibers in the final fibrous product. Moreover, a good bonding of the fibers is obtained in the final product.
