ASTM D2256 单纱法测量纱线的拉伸性能
ASTM D2256 规定了单纱法测量纱线拉伸性能的试验条件。测试纱线是从原料到面料生产过程中的一个重要环节。该工序确定原材料的质量并有助于控制最终产品的质量。
Pneumatic cord and yarn grips provide a convenient method for clamping fiber, cord, yarns and fine wires to reduce the problem associated with testing these materials. A specially designed horn with a smooth finish and a contoured surface with a graduated cam allows for easy loading and a stress reduced clamping area on the specimen. The clamping mechanism can be activated either automatically or through a foot switch. This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading. Pneumatic cord and yarn grips provide selectable clamping force to accommodate different materials and excellent follow-up action which compensates for decay of the holding force due to specimen creep.
