POROUS SHEET, AND POROUS COMPOSITE

The present invention addresses the problem of providing a porous sheet and a porous composite comprising the porous sheet, in particular, a porous sheet and porous composite for clothing, health articles, medical articles and sports articles, the porous sheet exhibiting good fitting, non-tightness and comfort directly after wearing or when stationary/resting, while also exhibiting tightness, fixation and stability properties and comfort during activities such as sport. The present invention pertains to a porous sheet comprising a thermoplastic elastomer composition (A), and having a pluralityof slits and/or pores, the porous sheet having a porosity of 5-80%, an anisotropic rate of at least 10%, and a stretch stress relaxation rate of at most 40% after being stretched to 500% and held for60 seconds. 本发明的课题在于提供能够兼顾刚穿着后或静止/休息时的贴合性、耐缠紧性和舒适性、以及体育等运动时的缠紧性、固定稳定性和舒适性的多孔片、以及包含该多孔片的多孔复合体，特别是用于服装、保健用品、医疗用品、体育用品的多孔片和多孔复合体。本发明涉及一种多孔片，其由热塑性弹性体组合物(A)形成，且具有多个狭缝和/或孔，所述多孔片的开孔率为5～80％，各向异性系数为10％以上，且以500％拉伸保持60秒钟后的拉伸应力松弛率为40％以下。
