The trapezoid method has been adopted to measure the tear strength of twelve fabrics. Comparison of properties between the denim and cotton plain cloth has been made by means of multi element regression analysis.

• 采用梯形撕裂法对12 种织物进行了撕破强力的测定，通过多元回归分析，对牛仔布和棉平纹布进行了性能比较，发现影响织物撕破强力的主要因素有纱线的断裂强力、织缩、交织阻力、织物密度和纱线断裂伸长率等。
