Abstract
Official abstract text for this publication.
A multi-layer tubular woven construct includes two or more layers including an innermost layer and layer A that is a layer other than the innermost layer, layer A including a monofilament yarn serving as a weft yarn, the weft yarn extending spirally and circumferentially around the tubular woven construct to form the weft, the weft including threads lying adjacent to each other, the adjacent weft threads of the monofilament yarn having intervals larger than the diameter of the monofilament yarn.
First claim
Opening claim text (preview).
The invention claimed is: 1. A multi-layer tubular woven construct comprising two or more layers comprising an innermost layer and layer A that is a layer other than the innermost layer, layer A comprising a monofilament yarn serving as a weft yarn, the weft yarn extending spirally and circumferentially around the tubular woven construct to form the weft, the weft comprising threads lying adjacent to each other, the adjacent weft threads of the monofilament yarn having intervals larger than the diameter of the monofilament yarn. 2. The multi-layer tubular woven construct of claim 1 , comprising layer B that is an inner layer relative to layer A, layer B comprising a multifilament yarn as a weft yarn. 3. The multi-layer tubular woven construct of claim 1 , comprising two layers comprising an inner layer formed of a multifilament yarn. 4. The multi-layer tubular woven construct of claim 2 , wherein the multifilament yarn comprises monofilaments with a diameter of 6 μm or less. 5. The multi-layer tubular woven construct of claim 3 , wherein the multifilament yarn comprises monofilaments with a diameter of 6 μm or less. 6. The multi-layer tubular woven construct of claim 2 , that satisfies formula: Df ≧3Dm, wherein Dm is weft density of layer A and Df is weft density of layer B. 7. The multi-layer tubular woven construct of claim 1 , that satisfies formula: Rm >Rh/300, wherein Rh is an outer diameter of the multi-layer tubular woven construct and Rm is a diameter of a cross section of the monofilament yarn. 8. The multi-layer tubular woven construct of claim 2 , that satisfies formula: Rm >Rh/300, wherein Rh is an outer diameter of the multi-layer tubular woven construct and Rm is a diameter of a cross section of the monofilament yarn. 9. The multi-layer tubular woven construct of claim 3 , that satisfies formula: Rm >Rh/300, wherein Rh is an outer diameter of the multi-layer tubular woven construct and Rm is a diameter of a cross section of the monofilament yarn. 10. The multi-layer tubular woven construct of claim 4 , that satisfies formula: Rm >Rh/300, wherein Rh is an outer diameter of the multi-layer tubular woven construct and Rm is a diameter of a cross section of the monofilament yarn.
