1 Scope

This standard specifies the test methods for textiles dynamic amount of negative ions measured by rubbing method, and gives the evaluation. This standard applies to all types of textile fabrics and products. This standard does not address due to the additional material containing radioactive substances in the air of negative ions and inspire safety evaluation textile products.

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Anion negativeions Negatively charged ions in the atmosphere after the capture molecules or atom electronic form, such as OH- (H2O) n and O-2 (H2O) n and the like. 3.2 Anion generation amount negativeionconcentration Textiles inspired by the mechanical friction when the number of negative ions per cubic centimeter to (a/cm3) as a unit. Principle 4 A certain volume of the test cartridge, the sample is mounted on the upper and lower two friction disc, friction under specified conditions, measured by air ions Measured sample and the sample itself, the mutual friction in the unit volume of space to inspire the number of negative ions, negative ions and recording the sample volume Versus time curve.

5 Equipment and Materials

5.1 air ion measuring instrument Air ion measuring instrument shall meet the following requirements. --- Collected using capacitive inhalation air ions, ion mobility can collect more than 0.15 (cm2/V · s) ions; --- Negative ions can be measured with a resolution of no greater than 10/cm3; --- Operating temperature and relative humidity ranges to meet the requirements of the test conditions; --- Can record the amount of negative change over time curve. ......
