The influences of elastic load, oily soil adherence and washing on sportswear were studied by measuring the change in stretch length of sportswear swatch. In the case of oily soil adherence in addition to elastic load, the oily soil penetrated into the polyurethane via diffusion and resulted in a change in the stretch length. When clothes containing the penetrated polyurethane were washed, the surfactant caused the penetration to spread inside the polyurethane, further changing the stretch length. However, the change with temperature was different in case of anionic surfactant (LAS-Na) from that of nonionic surfactant (EO8), and when a lot of LAS-Na diffused in the penetration process, the change in stretch length became negative and stretching became difficult. On the other hand, when subjected to elastic load and oily soil followed by washing, the wale direction and course direction showed the same conduct regardless of the temperature and EO8, and stretching became easy.It was found that the elasticity of sportswear degrade with the penetration of oily soil which diffuse inside the polyurethane with the elastic load. With regard to the surfactant of the detergent to use while washing, EO8 result in lower the elasticity of sportswear than LAS-Na.
