CA 2359480

The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes "nicking" the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the "nicking" of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.

La présente invention permet de conférer aux différents types de tissus un toucher très recherché grâce à l'immobilisation initiale de fibres individuelles dans les tissus voulus, suivie d'un traitement par abrasion, ponçage ou grattage d'au moins une partie du tissu voulu. Une telle procédure consiste à "ébrécher" les fibres immobilisées pour que celles-ci donnent au tissu voulu une force sensiblement équilibrée dans les directions de trame et de chaîne, tout en préservant le même toucher amélioré obtenu avec les procédés précédents. Par ailleurs, ce procédé permet d'améliorer de façon inattendue l'absence de boulochage des fibres synthétiques étant donné que "l'ébréchage" des fibres immobilisées a pour effet d'empêcher l'effilochage des fibres, et par conséquent, d'empêcher de manière quasi-certaine l'empelotage de ces fibres et la formation de boulochages indésirables sur la surface du tissu. En outre, cette invention concerne les tissus traités avec ce procédé.
