Abstract
The most difficult performance attribute to measure when evaluating a fabric softener has been static control. Several instrumental methods have been used in the past, all with limited success. The most frequently used method has been a subjective evaluation by an experienced operator, but this also has obvious short-comings. The topic method is based on a Faraday Cage. Test swatches are removed from the dryer and placed in an insulated stainless steel tank. As each swatch is removed, a corresponding charge is induced on the tank, which is measured by a high impedence volt meter.
