<p>A method is disclosed for production of a fibrous product containing curled fibers. Rectilinear bi-component fibers (17) are applied to the upper side of a raw material sheet (2) before it is introduced into a defibrator (1). Immediately before the introduction, a heating (at 8) is effected. When the rectilinear bi-component fibers (17) are introduced into the defibrator (1), the beater bars (9) would effect a curling effect thereby providing a raw material comprising 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.</p> |
