Background Abrasion resistant fabrics refer to textile materials that have the ability to resist physical damage such as abrasion, scraping, abrasion, etc., and are capable of withstanding repeated rubbing without being easily damaged, fuzzed, pilled, thinned, or perforated. Wear resistant fabrics can be made into work wear, protective apparel, outdoor equipment, furniture fabric, automotive interiors, luggage, shoe materials, industrial cloths, and the like. The tensile strength detection is used for evaluating the reliability of the fabric when the fabric bears external forces such as weight, pressure and the like by measuring the breaking strength and the elongation of the fabric in the stretching process. The disclosed China patent, publication No. CN220794880U, discloses a tensile strength detection structure for textile fabric processing, which comprises a base, a mounting frame fixedly mounted at the top of the base and a controller fixedly mounted outside the mounting frame, wherein the number of the mounting frames is two, the two mounting frames are respectively positioned at the edges of the left side and the right side of the top of the base, two sliding seats are arranged between the mounting frames, the tops of the two sliding seats are welded with mounting seats, two clamping components are arranged on the opposite sides of the mounting seats, a stretching mechanism for displacing the two sliding seats is arranged on the mounting frames, and the clamping components consist of a storage rack, a first electric push rod and clamping plates.

Although the clamping component of the tensile strength detection structure adopted in the above-mentioned publication can fix the fabric, the linear stretching mechanism can only generate unidirectional stress, and cannot reproduce the multidirectional stress state of the curved surface, for some fabrics for manufacturing curved surface products, such as wear-resistant fabrics for manufacturing sails, airbags, sports protective equipment and the like, the curved surfaces of these curved surface products are stressed, and the application stress of the curved surface products is not static, just like the sails can be continuously expanded and contracted like breathing in navigation, and the prior art only adopts plane stretching detection, so that the multidirectional stress distribution on the curved surfaces cannot be reflected, and the curved surface stress state cannot be dynamically simulated, so that the prior detection method is completely inapplicable.
