Abstract: Based on existing negative ion test method of textiles,the amount of negative ions were tested by coating the nano germanium powder on the fabric.The advantages and disadvantages of average value method and five point value method in the evaluation of fabric negative ion were compared and analyzed.The five point value method refered to the average value of five maximum points in the frictional stability interval as the amount of negative ion generated by the fabric.The average value method refered to the average value in the friction stability interval as the amount of negative ion generated by the fabric.6 groups of experiments were carried out to compare the two methods by analyzing the standard deviation of data,and to study the advantages and disadvantages of two methods.The experimental results showed that the two evaluation methods were of practical significance.Compared with the average value method,the five point method of value calculation was less and simple,which can quickly reflect the experimental results.The average value method had little error in data,and can accurately reflect the amount of negative ion generated by fabric.
