Abstract: The present invention discloses a tubular fabric with strengthened fabric structure, formed from interlaced warp yarns and weft yarns where at least one of the warp yarns is spandex yarn. The tubular fabric is characterized in that the spandex yarn accounts for 6%-12% of the total fabric weight, the spandex yarn has a floating line on the inner wall surface not shorter than 3 weft yarns, and the weft density is between 14-30% weft/cm. Due the special weaving structure, which results in the long floating line of the spandex yarn, the resulting tubular fabric have a large amount of spandex yarns covering its inner wall surface, thereby enhancing its strength and effectively prevent perforation by the steel wire.
