摘　　要：斜面法是测试织物弯曲性能最普遍的方法,但是斜面法本身有一定的局限性。针对这种情况,制作出了一种新弯曲性能检测仪,由自动送样装置和图像处理的软件程序两部分组成,来测试织物的弯曲性能,文中称之为新方法。分别测试了20种织物的弯曲性能,得到了两种方法的伸出长度读数,并用积分计算了弯曲状态下曲线的长度。结果表明:两种方法得到的伸出长度读数之间,积分算法得到的长度与伸出长度读数之间都具有高度线性相关关系,说明积分算法的结果可以表征新方法的伸出长度;两种方法的弯曲刚度之间相关系数的平方R2=0.970,为高度正相关,说明提出的测试织物弯曲性能的新方法是可行的。Incline method is the most common method used to test the bending behavior of fabrics, but it has somelimitations. Aiming at this, a new bending test instrument called a new method was made in this paper, which is composedof two parts, the automatic sample conveying device and the image processing program. The bending behaviors of 20fabrics were tested respectively, and the readings of overhanging length were gained. The length of the curve underbending condition was figured out with integral. The experimental result shows that the readings of two methods, the resultsof integral calculation and the readings of the new method have high linear correlation. This indicates that the results ofintegral calculation can represent the overhanging length of the new method; the square of bending rigidity correlationcoefficient of two methods is R^2 =0.970,high-positive correlation. This shows the new method is feasible.
