Abstract

L'invention concerne des surfaces textiles pliables, en particulier des tricots, lesquelles surfaces textiles présentent des sections successives renforcées et non renforcées. L'invention se caractérise en ce qu'une rigidité différente de la surface textile et la pliabilité souhaitée sont obtenues par l'utilisation de matériaux alternés ou selon des motifs dans cette surface textile et par un traitement consécutif sur toute la surface, tel qu'un traitement thermique ou chimique ou une irradiation.
