CA 2389068

Tufted carpets bonded with thermoplastic binders and having improved resistance to fuzz formation due to removal of pile yarn filaments from tuft bundles comprise one or more backings, face yarn that forms a pile on one side and stitches on an opposite side, a thermoplastic binds stitches and the backing or backings, and an organic polymer that bonds filaments of the stitches. Processes for making carpets comprise applying to a stitched side of a tufted backing a liquid stitch bind composition comprising an organic polymer component, removing a liquid component of the composition to bond filaments of the stitches and bonding stitches and one or more backings with a thermoplastic binder that is melted or applied as a melt in contact with the stitched side and the backing or backings and solidified.

L'invention concerne des tapis ou moquettes tuftés assemblés par le biais de liants thermoplastiques et présentant une résistance améliorée au peluchage. A cet effet, on retire les filaments de fil de velours des touffes tuftées. Ces tapis ou moquettes comprennent un ou plusieurs supports de base, du fil d'endroit formant un velours sur un côté et des coutures sur le côté opposé, un liant thermoplastique pour la liaison des coutures et du ou des supports de base, et un polymère organique assurant la liaison des filaments de couture entre eux. L'invention concerne des procédés de fabrication de tapis ou moquettes consistant à appliquer du côté couture d'un support de base tufté une composition liquide de liaison de couture à base de composant polymère organique, à extraire un composant liquide de la composition pour assurer la liaison des filaments de couture et à lier les coutures et un ou plusieurs supports de base au moyen d'un liant thermoplastique qui est fondu ou appliqué sous forme fondue au contact du côté couture et du ou des supports de base puis solidifié.
