Webbing for seat belt
First Claim
1. A webbing for a passenger restraint belt, comprising:
- warp yarns and weft yarns comprising synthetic filaments and woven so as to extend orthogonally to each other,wherein at least one of the warp yarns and the weft yarns are formed using synthetic filaments comprising first filaments and second filaments,wherein the second filaments are provided in the first filaments and have a melting temperature lower than that of the first filaments,wherein the synthetic filaments are middle shrinking synthetic filaments which are contracted at a dimensional shrinkage rate of 15% to 20% after the second filaments are melted under conditions of 150°
C. or more for 180 seconds or more, andwherein the webbing has a weight of 60 g/m or less, a tensile strength of 25 kN or more, and a retention rate after hexagonal bar abrasion of 70% or more.

Abstract
A webbing can be used in a passenger restraint belt. The webbing includes warp yarns and wefts comprising synthetic filaments and woven so as to extend orthogonally to each other. At least one of the warp yarns and the weft yarns are formed using synthetic filaments comprising first filaments and second filaments in which the second filaments are provided in the first filaments and have a melting temperature lower than that of the first filaments. The synthetic filaments are middle shrinking synthetic filaments which are contracted at a dimensional shrinkage rate of 15% to 20% after the second filaments are melted under conditions of 150° C. or more for 180 seconds or more. The webbing has a weight of 60 g/m or less, a tensile strength of 25 kN or more, and a retention rate after hexagonal bar abrasion of 70% or more.
