Rapid Measurement of Short Fiber Content on Hertel Sample

This paper offers a new method of measuring short fiber content of cotton fibers. The method is composed of two parts： one is Hertel sampling and the other is image testing. With the help of fiber mixer, a thin and even cotton net is obtained on which we can get Hertel sample by using a sliver clamp. The near micro optical mechanism consists of one large area CCD and one lens with long focus. This mechanism is able to measure every cotton fiber of the test beard accurately and makes it possible to measure accumulating fibers＇ amounts. On this base we can calculate short fiber content of cotton, and the experiment results show that this method is efficient.     

锯齿式加工过程中棉花品质的变化

为了给棉花采后加工的减损、保护棉花纤维内在品质指标和改善棉花加工工艺提供一定的参考依据,本文提出基于多项棉花纤维品质指标构造棉花综合品质指标(CCVIL),并研究该指标在典型加工工艺流程中的变化。结果表明:当前典型加工工艺流程中第4道工序(提净式籽棉清理)、第6道工序(锯齿轧花)和第9道工序(锯齿式皮棉清理)分别导致CCVIL降低0.0921、0.1851、0.285。
