Warp and weft fabric based on multifilament technical yarns predominantly without torsion and method of production.

摘要

The invention relates to a fabric and weft based on multifilament technical yarns, of which at least 80% by weight of the yarns have in combination the following characteristics: BR/ (a) - the yarn count, for a basis weight given fabric, is superior to that traditionally used, BR/ (b) - the yarns do not exhibit torsion greater than the original twist of the yarns before weaving, which are, in the same proportion, yarns at 0 torsion turn / m, BR/ (c) - the width of the threads is over the entire length of the threads, greater than or equal to the original width of the threads before weaving, BR/ These threads constituting all threads in the direction with the largest proportion of yarn by weight when the weight ratio of the weft and warp yarns is greater than or equal to 80/20 and all yarns of the fabric when this ratio is less than 80/20, the volume ratio of fibers being substantially constant in the fabric and greater than or equal to elui of a traditional fabric with equal or lower threads. / P
