Abstract: Base consisting in a leno fabric, with flexible strips incorporated into it longitudinally, in the direction of the warp, linked successively through each one of the weft courses, in such a way that the threads of same evolve by passing from the face to the back of the fabric, and successively, with respect to adjacent strips, in accordance with a taffeta texture. The flexible strips are arranged in groups of two or more, regularly or irregularly spaced apart from each other and with respect to the connecting warp threads, defining open bands for the passage of air and light.
