毛绒束纤维断裂强度试验方法GB/T27629-2011
根据GB/T27629-2011标准，毛绒束纤维断裂强度试验方法主要包括以下步骤：
- 试样制备：将毛绒束纤维切割成长度为100mm、宽度为20mm的长条状试样，试样宽度应该沿着毛绒束纤维方向。
- 测试仪器准备：按照规定配置好试验机，包括夹具、曲率半径、载荷传感器等。
- 试验环境准备：将试验环境温度控制在20℃左右，相对湿度控制在65%左右。
- 试验操作：将试样夹具固定在试验机上，设定试验机的移动速度为50mm/min，在载荷传感器的监测下进行试验，记录试样断裂时的最大载荷值。
- 数据处理：根据记录的试验数据计算出毛绒束纤维的断裂强度。
需要注意的是，试验过程中要避免试样夹具对试样的影响，试验时间不宜过长，同时应注意测试环境的控制。
通过以上步骤可以得到毛绒束纤维的断裂强度值。这个指标可以用来评估毛绒束纤维的质量和使用性能，帮助生产厂家提升产品质量，满足市场需求。
