A hot-melt fiber is woven as the row material in the present invention , and then the row material is cut by the ultrasonic mold to form a fixed band of a predetermined shape, so that the respective sides of the fixed band appear to be flexible and tight without batting to have good tactile feeling. Then, ultrasonic friction is utilized to generate heat to weld one end of the fixed band to the cover, and the other end of the fixed band is welded with a Velcro, moreover, ultrasonic heat fusion is implemented to the free end of velcro for the free end of velcro to form a flat part which is conveniently to be applied with a force. In such a processing way, the appearance of the overlapping part of the fixed band and the cover is strengthened. When the fixed band is tied on the face of the person, it has more comfortable feeling overall to greatly promote the whole usage quality.本發明係以熱熔性纖維織成一素材,然後透過超音波模具裁切該素材,使之成型出預定形狀之固定帶,俾令該固定帶各邊係呈柔韌緊實狀,且沒有毛絮的具有良好觸感,繼之,利用超音波摩擦生熱的將固定帶一端熔接至罩體,以及在固定帶另端熔接有一魔鬼氈,更以超音波熱融該魔鬼氈自由端,使魔鬼氈自由端形成一可方便施力之平整部。此加工方式,除強化固定帶與罩體疊接部位之外觀性外,且使該固定帶在繫結於吾人臉部時,整體具有較佳之舒適觸感,用以大大地提高整體使用品質。10‧‧‧固定帶11‧‧‧邊20‧‧‧罩體30‧‧‧魔鬼氈31‧‧‧平整部
