PROBLEM TO BE SOLVED: To obtain a comfortable feeling of wear owing to change of elasticity and viscosity of a string body during using.SOLUTION: An eye bandage 1 as a cover with an ear hook string is constituted of a cover part 2 and one string body 3. The string body 3 is obtained by spirally winding a wound yarn around a string-like or belt-like core yarn comprising a thermoplastic elastomer material which shows elasticity of rubber or the like, is extended by the addition of force, and is constricted to an original length by removing force. Since tightening received from the string body is gradually softened when a body temperature is transmitted to the string body, by using the thermoplastic elastomer material changing the characteristics by the body temperature as the core yarn molded in a filamentous or belt-like shape, a comfortable feeling of wear can be continuously obtained.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】使用中に紐体の弾性、粘性が変化し快適な装着感が得られるようにする。【解決手段】耳掛け紐付きカバーである眼帯1は覆部2と、1本の紐体3とから構成されており、紐体3はゴム等の弾性を示し力を加えると伸び、力を除くと元の長さに収縮する熱可塑性エラストマ材から成る紐状又は帯状の芯糸に、巻糸が螺旋状に巻き付けられている。糸状又は帯状に成形した紐体の芯糸として、体温によって特性が変化する熱可塑性エラストマ材を用いることで、体温が紐体に伝達すると紐体から受ける締め付けが次第に緩和されてゆくので、継続して快適な装着感が得ることができる。【選択図】図1
