Title (EN) NON-BLOCKING SEAM TAPE
(FR) RUBAN D'ETANCHEITE ANTI-BLOCAGE POUR COUTURES
Abstract:
(EN) A non-blocking waterproof seam tape for covering sewn seams of garments is taught. The seam tape is comprised of an expanded porous polytetrafluoroethylene layer in which one surface has been densified, a cured or partially cured polyurethane adhesive layer, and a thermoplastic hot melt adhesive layer. The densified surface of the expanded porous polytetrafluoroethylene layer prevents the entry of the thermoplastic adhesive through cold creep into the expanded porous polytetrafluoroethylene layer while the seam tape is stored in roll form.
(FR) Ruban d'étanchéité anti-blocage destiné à recouvrir les coutures des articles vestimentaires. Le ruban est constitué d'une couche de polytétrafluoréthylène poreux et expansé dont on a densifié l'une des surfaces, d'une couche adhésive de polyuréthane entièrement ou partiellement durci, et d'une couche de colle fusible thermoplastique. La surface densifiée de la couche de polytétrafluoréthylène poreux et expansé empêche l'entrée dans celle-ci, par fluage à froid, de la colle thermoplastique lorsque ledit ruban est stocké sous forme enroulée.
