    Abstract: The purpose of the present invention is to provide an orthotic: which achieves both the orthotic force that is required to modify the shape of or improve function of the body, and the ability to track friction, compression and the like between an orthotic site and the orthotic that occurs during operation; and which is easy to fit and does not negatively impact outer appearance when fitted. This orthotic has a region B that expresses orthotic force when the orthotic is fitted. The region B is, with respect to any orthotic site, composed of a region B1 that covers the orthotic site, a region B2 that is a support region for causing orthotic force to act, and a region B3 for coupling the region B1 and the region B2 together. A structure that is used for the region B is a stretchy woven structure. The rate of elongation during a load of 100 N/5 cm is 1.0% to 20% in the warp and weft directions or one of said directions. The orthotic further has a region A that covers the periphery of the orthotic site, and the region A is preferably composed of at least one type of stretchy structure.

    Abstract: The present invention relates to a tubular fabric useful for hoses used to transfer fluid and powder and protect wire-like materials such as wires, cables, and electric wire tubing, tubular filters, base materials for artificial blood vessels, and the like. Provided is a tubular fabric that is woven by interlacing warp yarn and weft yarn and has a difference in outer diameter of 10% or less in the warp direction of the tubular fabric, wherein the following formula is satisfied: (L2 − L1)/L1 ≥ 0.1 wherein L1 is a distance between marked lines when compressive stress of 0.01 cN/dtex is applied in the warp direction of the tubular fabric with the marked lines drawn on the outer circumference of the tubular fabric at a distance five times the maximum value for the fabric outer diameter measured in a state where stress is not applied to the tubular fabric, and L2 is the distance between the marked lines during elongation at a stress of 0.01 cN/dtex in the warp direction of the tubular fabric with the marked lines drawn on the outer circumference of the tubular fabric at a distance five times the maximum value for the fabric outer diameter measured in a state where stress is not applied to the tubular fabric.
