STRUCTURE COMPRISING LOW-RESILIENCE ELASTIC MEMBER AND HIGH-RESILIENCE ELASTIC MEMBER
FIG4 is a diagram schematically showing a rear view (back view) of the sportswear of FIG3
FIG4 shows a rear view (back view) of the sportswear of FIG3. The high-resilience elastic member 2 (mesh body) made of the high-resilience elastic thermoplastic elastomer (Y) is disposed in a cross shape at shoulder and arm base portions. The high-resilience elastic member 2 composed of the cross-shaped high-resilience elastic thermoplastic elastomer (Y) is disposed by being joined over the normal cloth 3.

['1. A structure comprising: one or more low-resilience elastic members 1 made of a thermoplastic elastomer (X); and one or more high-resilience elastic members 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 hydrocarbon 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.']
