Abstract
A seat belt (safety belt) webbing has lateral stiffness, low longitudinal stiffness, abrasion resistance, and user comfort provided by a soft, round edge of the webbing. In a loom, a pick needle is used to move both a monofilament and multifilament yarn together across the full width of the loom shed. A higher tension is applied to the monofilament yarn so that the monofilament yarn does not protrude beyond the edges of the webbing. In the selvedge (marginal) portions of the web a single ply warp yarn is provided, while in the central portion a double ply warp yarn is provided. The selvedge portions may have a reverse twill weave. Two catchcord yarns, a binder thread and a locking thread, are knit at one edge portion of the webbing.
