Abstract
A load bearing system including a load-bearing textile strap, including an article, such as a backpack or a climbing harness, that includes such load bearing system. The strap includes at least one woven portion and at least one non-woven portion. The woven portion has warp yarns extending along a longitudinal direction of the strap interlaced with at least one weft yarn, the woven portion having a first width. In the non-woven portion the warp yarns are spread transversely so that the non-woven portion has a second width greater than the first width of the woven portion.
Description
