margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">　　挠性剑带现在多采用多层复合材料制成,它是以多层高强长丝织物为基体,浸渍树脂层压而成,表面被覆盖耐磨层。一般厚2.5～3mm。剑带在工作时要经受反复的弯曲变形,要求弹性恢复性能好,耐磨,有足够的强度,在工作寿命期内,带边不破损,表面不起皮,带体不分层,不断裂。有的挠性剑带采用钢带作为材料,钢带的刚性、弹性好,梭口内可不用导向件,但钢带开孔较困难,不能以轮齿传动,故引纬幅宽受限制。与钢带相仿的是碳素纤维制成的剑带,它具有钢带的优点,并质量轻,但价格较贵。</span></p><p style="max-inline-size: 100%;
