  • the present invention relates to a primary base fabric for obtaining a tuft carpet by planting pile yarn.

And the long fiber which comprises a primary base fabric is restrained and joined by the thermocompression bonding part.

  • the present invention is to provide a tufted carpet primary base fabric in which the long fibers in the primary base fabric are bonded to each other even after the tufting step, and the primary base fabric itself maintains a good shape.
  • the present inventor has succeeded in obtaining a polyester long-fiber nonwoven fabric with higher rigidity by making the cross-sectional shape of the long fiber into a shape that has not been known conventionally. And when this polyester long fiber nonwoven fabric was applied to a tuft carpet primary base fabric, there was little damage to the long fibers by the tufting needle in the tufting process, and there was little breakage of the bonded part due to fusion of the long fibers, even after the tufting process The present inventors have found that the rigidity of the primary base fabric is maintained and the shape can be maintained well, and the present invention has been achieved.

Abstract

Le problème décrit par la présente invention est de fournir un tissu de base principal d'une moquette tuftée dans lequel, même après le processus de touffetage, les jonctions entre les fibres longues dans le tissu de base principal sont maintenues et la stabilité de forme est conservée. Ce tissu de base principal de moquette tuftée est conçu à partir d'un tissu non tissé, dans lequel les fibres longues, d'une finesse de 10 décitex ou plus sont les fibres constitutives. La section transversale des fibres longues est caractérisée par la liaison d'extrémités de fond sensiblement en forme de « Y », en haut et en bas et à gauche et à droite (ci-dessous, cette forme est désignée « forme sensiblement en Y4 »). Les fibres longues sont en polyester de type composite, les parties (6) sensiblement en forme de « V » de la forme sensiblement en Y4 étant constituées à partir d'un polyester à faible point de fusion et la partie (5) restante, sensiblement en forme de « + » est constituée à partir d'un polyester à point de fusion élevé. Les fibres longues sont liées ensemble par la fusion du polyester à faible point de fusion.
