大豆/涤混纺纱混纺比及其不匀率的测试与计算方法

为了研究大豆蛋白纤维这种新型的纺织原料混纺比的测试方法,利用数理统计原理,采用密度梯度法对大豆/涤纶(65/35)混纺纱混纺比进行了测试和计算,该方法不仅可以得到混纺比均值,而且可以得到混纺比标准差,粗纱和细纱混纺比均值的控制范围分别为(63.64%,65.32%)和(64.16%,66.17%),粗纱和细纱混纺比标准差的控制限分别为2.89%和3.56%,同期细纱用溶解法实验结果为64.5%,2种方法误差为1.1%。

The Method to Determine the Blended Ratio of Soybean Protein Fiber/Polyester Blended Ring-Spun Yarn

In order to study the method to determine the blended ratio of the soybean protein fibers, the calculation of the mean and standard deviation of the blended ratio of soybean protein fiber/Polyester(65/35) blended yarn by the statistical theory and density gradient method is discussed in this paper. The method can derive not only the mean but also the standard deviation of the blended ratio of the soybean protein fiber/polyester brended yarn. The control range of blended ratio of roving and ring-spun yarn is (63.63%, 65,32%) and (64.16%, 66.17%). The control range of the standard deviation of roving and ring-spun yarn is 2.89% and 3.56%. The blended ratio of the ring-spun yarn by the chemical dissolution is 65.5% at the same time. The error of the two methods is only 1.1%.
