Fineness testing of ramie fiber with WIRA airflow meter

Conventional weight method is used to test the ramie fiber fineness based on the cut-middle section of the fiber,which has defects on small sample quantity,inadequant representativeness,and the results easily influenced by subjective factors.Therefore,the paper attempt to develop a fast and accurate test method for ramie fiber fineness and study the feasibility of testing ramie fiber fineness by using WIRA airflow meter.The sample quantity and the arrangement manner are determined through experiments.Comparative study with the weight method is conducted,and a regression equation between flow readings and metric counts is established.The feasibility of ramie fiber fineness testing by using WIRA airflow meter is demonstrated by the test data.
