STRUCTURE COMPRISING LOW-RESILIENCE ELASTIC MEMBER AND HIGH-RESILIENCE ELASTIC MEMBER

摘要

A problem to be solved by the present invention is to further improve a performance of a conventional structure having a low-resilience elastic member and a high-resilience elastic member and, particularly, to provide a structure such as clothes, a supporter, a sock, or footwear giving a soft wearing feeling while making a body motion extremely smooth during exercise and a wearer less tired. The present invention provides a structure comprising: a low-resilience elastic member 1 made of a thermoplastic elastomer (X); and a high-resilience elastic member 2 made of a thermoplastic elastomer (Y), wherein the thermoplastic elastomer (X) and the thermoplastic elastomer (Y) are each independently made of a resin composition containing(a) 100 parts by mass of a hydrogenated block copolymer having a weight average molecular weight of 200,000 or less for 50 to 100 mass% and formed by hydrogenating a block copolymer composed of at least two polymer blocks A made up of structural units derived from a vinyl aromatic compound and at least one polymer block B made up of structural units derived from a conjugated diene compound,(b) 50 to 300 parts by mass of a softener, and(c) 3 to 50 parts by mass of a polyolefin resin relative to a total of 100 parts by mass of (a) and (b), wherein the thermoplastic elastomer (X) has a modulus of 1.0 MPa or less at elongation of 100 % and a hysteresis loss rate of 70 % or more, and wherein the thermoplastic elastomer (Y) has a modulus of 1.0 MPa or less at elongation of 100 % and a hysteresis loss rate of 40 % or less.
