CA 2567502

A hook-and-loop fastener made of fabric in which fibers constituting the ground fabric have been fusion-fixed to fibers constituting engaging elements and which has no back coating layer and is excellent in flexibility and durability. It is a hook-and-loop fastener which is composed of ground wefts (.alpha.1), ground warps (.alpha.2) including binder fibers, and piles (.alpha.3) and in which the piles (.alpha.3) have been fixed through the fusion of the binder fibers as a component of the ground warps (.alpha.2), the ground wefts (.alpha.1), ground warps (.alpha.2), and piles (.alpha.3) comprising polyester fibers, the proportion (by mass) of the ground wefts (.alpha.1) to the ground warps (.alpha.2), .alpha.1/.alpha.2, being from 40/60 to 80/20, and the proportion (by mass) of the sum of the ground wefts (.alpha.1) and the ground warps (.alpha.2) to the piles (.alpha.3), (.alpha.1+.alpha.2)/.alpha.3, being from 90/10 to 50/50.

L'invention concerne une fermeture velcro en tissu dans laquelle les fibres constituant le tissu de base ont été attachées par fusion aux fibres constituant les éléments s'accrochant et qui ne possède pas de couche dorsale et est excellente en terme de flexibilité et de résistance. C'est une fermeture velcro qui est composée de trames de base (.alpha.1), de chaînes de base (.alpha.2) incluant des fibres de liaison, et du velours (.alpha.3) et dans laquelle le velours (.alpha.3) a été lié par fusion des fibres de liaison comme composant des chaînes de base (.alpha.2), les trames de base (.alpha.1), les chaînes de base (.alpha.2), et le velours (.alpha.3) comprenant des fibres de polyester, la proportion (en masse) des trames de base (.alpha.1) par rapport aux chaînes de base (.alpha.2), .alpha.1/.alpha.2, étant de 40/60 à 80/20, et la proportion (en masse) de la somme des trames de base (.alpha.1) et des chaînes de base (.alpha.2) par rapport au velours (.alpha.3), (.alpha.1+.alpha.2)/.alpha.3, étant de 90/10 à 50/50.
