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.

Abstract: The purpose of the present invention is to provide a biodegradable block copolymer which combines high conformability with excellent degradability. The present invention provides a block copolymer which comprises a poly(alkylene glycol) block and a poly(hydroxyalkanoic acid) block, wherein the proportion by mass of the poly(alkylene glycol) block to the whole mass is 10-60%, the block copolymer having a carbon-nucleus relaxation time T1? regarding the carbonyl carbon atom of 20 ms or less and satisfying expression 1. ?=?1×?2=20 (expression 1) ?1 is the degree of crystallization of the poly(alkylene glycol) block. ?2 is the degree of crystallization of a poly-A block, where A is a repeating unit, among the repeating units contained in the poly(hydroxyalkanoic acid) block, that is the highest in the degree of crystallization of the homopolymer made up of the same repeating units alone.
