Patent ID: 11299826

Abstract:
Provided is a tubular fabric that has a homogeneous structure along its outer circumference and excellent shape-stability and that is useful as hoses for transferring a fluid or powder or for protecting linear materials such as a wire, a cable, and a conduit, tubular filters, and medical base materials such as an artificial blood vessel. The tubular fabric includes a wall part that is woven by interlacing a warp yarn and a weft yarn and that has a double weave structure, a weft yarn in an outer layer and a weft yarn in an inner layer being not intersected with each other. The tubular fabric preferably has a circularity c of 0.8 or more and 1.2 or less, the circularity c being represented by the following equation of an outer diameter b perpendicular to an outer diameter a with respect to the outer diameter a, the outer diameter a being obtained by measuring a location corresponding to a fabric width A in weaving of the tubular fabric. Circularity c=a/b.
