CA 2621509

A sealing tape that overcomes a practical restriction such that a knit must be used on the surface of sealing tape at use in fiber products obtained by sewing or fusion bonding of a fiber laminate, and that without detriment to appearance and tactile sensation, excels in durability and realizes lightweight, thickness reduction and high comfort. There is provided a sealing tape having a substrate film, a woven fabric superimposed on one major surface of the substrate film and an adhesive layer superimposed on the other major surface of the substrate film, characterized in that the sum of cover factors calculated with respect to each of the warp and weft constituting the woven fabric, CFtotal, is in the range of 500 to 1400. CFtotal = CFm + CFt CFm: warp cover factor, and CFt: weft cover factor.

L'invention concerne un ruban d'étanchéité permettant de surmonter une restriction pratique selon laquelle un tricot doit être utilisé à la surface d'un ruban d'étanchéité lors d'une utilisation pour des produits fibreux obtenus par liaison par fusion ou couture d'un laminé fibreux, et ceci sans affecter l'apparence et la sensation tactile, en présentant une excellente durabilité, un poids léger, une épaisseur réduite et un niveau élevé de confort. Le ruban d'étanchéité selon l'invention comporte un film substrat, un tissu tissé superposé sur une surface principale du film substrat, et une couche adhésive superposée sur l'autre surface principale du film substrat, ledit ruban d'étanchéité étant caractérisé en ce que la somme des facteurs de couverture calculée par rapport à chacune des trames et chaînes constitutives du tissu tissé, CF<SUB>total</SUB>, est comprise entre 500 et 1 400. CF<SUB>total</SUB> = CF<SUB>m</SUB> + CF<SUB>t</SUB> CF<SUB>m </SUB>: facteur de couverture de trame, et CF<SUB>t </SUB>: facteur de couverture de chaîne.
