摘要： Provided is a textile vascular prosthesis having various properties required of it and having a repair function that is similar to that of blood vessels in a living body and relies on spontaneous healing ability of a human body. The inner layer-covering rate C (%) is defined by the formula: C = W 1 × D 1 + W 2 × D 2 × 25.4 − W 1 × W 2 × D 1 × D 2 / 25.4 × 25.4 × 100 , where D1 is the warp density (ends/25.4 mm) of an outer layer, D2 is the weft density (picks/25.4 mm) of the outer layer, W1 is the apparent width (mm) of a warp yarn of the outer layer, and W2 is the apparent width (mm) of a weft yarn of the outer layer. The inner layer-covering rate C (%), representing the coverage of an inner layer formed of warp yarn 3 and weft yarn 4 by the outer layer formed of warp yarn 1 and weft yarn 2, is 15% ≤ C ≤ 75%.

摘要： The present invention aims to provide a fiber structure which can be used as a cell scaffold material showing improvement in both the cellular adhesiveness and the cell growth capacity, which improvement was achieved by controlling the fiber orientation in the multifilament and the average fiber diameter, which are physical properties. The present invention provides a fiber structure which can be used as a cell scaffold material, which fiber structure comprises a multifilament formed by bundling monofilaments having an average fiber diameter of 1 to 15 µm, wherein each of the monofilaments satisfies the condition of the following Formula 1: (Y/X)×100≥50 ... Formula 1 [wherein in Formula 1, X represents the number of monofilaments for which the average crossing angle is investigated, and Y represents the number of monofilaments having an average crossing angle of not more than 25° in X].
