<p>In a thin and light webbing (4) having a high strength per warp yarn unit, maintaining abrasion resistance, and using as a warp yarn (2) a very strong polyester multifilament yarn for a seat belt made by fine single-yarn fibers, the warp yarn is obtained by performing a twisting process of a high degree of twist on a polyester multifilament yarn made of fine single-yarn fibers so as to be highly bound. The polyester multifilament yarn of fine single-fibers is woven at the maximum stretch ratio in a yarn making process to obtain very-strong polyester fiber for a seat belt. A multifilament yarn and/or a monofilament yarn of polyester is/are used as weft yarns (3). By making the weft yarns and warp yarns cross each other so as to be woven in a belt like configuration, a webbing having a very high strength per unit of warp yarns, using low-cost base yarns, and maintaining abrasion resistance is obtained. <IMAGE></p> |
