Summary:There is provided a process which comprises the step of subjecting a just produced spunbond web to a high flow rate, heated stream of air across substantially the width of the web to very lightly bond the fibers of the web together. Such bonding should be the minimum necessary in order to satisfy the needs of further processing yet not detrimentally affect the web. The fibers of the web may be monocomponent or biconstituent and the web should be substantially free of adhesives and not subjected to compaction rolls. Procédé consistant à soumettre un non tissé venant d'être produit à un flux d'air chaud à fort débit sur pratiquement toute sa largeur de sorte que les fibres soient légèrement liées ensemble, ces liaisons restant suffisamment légères pour ne pas affecter le traitement ultérieur du non tissé. Les fibres du non tissé peuvent être à un ou deux composants, tandis que le non tissé doit être sensiblement exempt d'adhésifs, et ne pas être soumis à des rouleaux presseurs.
