激光衍射法用于纤维细度测试的研究郭顺，郑秀岐，谭巧娣天津商检局细度测试是纤维品质检测的主要指标，在评价其物理性能方面起决定因素。国内常采用投影法和气流法测试纤维的细度，这两种方法都存在一定缺陷。前者是利用纤维投影仪对纤维进行逐根测量，效率较低，易造成... Laser Diffraction Method for Fiber Fineness Testing Guo Shun, Zheng Xiuji, Tan Qiaoqi Fineness testing by Tianjin Commodity Inspection Bureau is the main indicator of fiber quality testing, and it is a decisive factor in evaluating its physical properties. In China, the fineness of fibers is often measured by the projection method and the air flow method. Both of these methods have certain defects. The former is the use of fiber projectors to measure the fiber by the root, the efficiency is low, easy to cause ...
