Abstract: On the basis of analyzing the existing testing methods of anion-generating capacity, through selfdeveloped FFZ471-Ⅱ textile negative ion tester, the testing and evaluation method for the anion-generating capacity of the filling was determined by discussing the covered fabric, filling content and test time. The test results showed that when the covered fabric is cotton fabric, the filling content is 30 g, and the test time is 3min, the testing and evaluation method for the anion-generating capacity of the filling has good data stability, high reproducibility and comparability.

Key words: filling; anion; generating capacity; testing; evaluation
