What is the degree of tearing of paper?

Abstract: 这篇文章阐述了纸张的撕裂程度特性，即纸张对撕裂力的抵抗能力。撕裂程度通常用mN表示，通过纵向和横向的测量获得。文章介绍了使用Elmendorf和Trouser撕裂仪器来测试撕裂程度，并指出撕裂性受到纤维精炼程度和填料质量及数量的影响。此属性在封面纸、包装纸、证券纸和信封纸等多种应用中尤为重要。文章还提到了相关的标准测试方法，如TAPPI T414、TAPPI T470和ISO 1974。

The tearing property of paper gives a measure of a piece of paper's resistance to the tearing forces it is subjected to. It is measured in mN both longitudinally and transversely. Two types of instruments are used, the Elmendorf and Trouser tearing instruments. Tear resistance depends on the degree of fiber refining and the quality and quantity of fillers used. This property is important in many applications involving cover, wrapping, bond and envelope stocks. The standard test methods followed are TAPPI T414, TAPPI T470 and ISO 1974.
