Abstract: Characteristic indexes variation of fabric hairiness with fuzzing numbe are tested using the fabric sigle-sided compressing tester, the objective evaluation measurement for fuzz resistance of fabric is proposed. Studies have shown that: characteristic indexes of fabric hairiness raise along with fuzzing number increses, but they raise greatly when the fuzzing number is small and tend to be stable along with continue increasing of fuzzing number; the fuzz resistance of fabric can be evaluated using the rates of change of characteristic indexes of fabric hairiness after certain times (20 times) of fuzzing relative to the the original sample; among the 4 indicators of changing rate of hairiness length, changing rate of cut-off point presure, changing rate of comressing work and changing rate of compressing specific work, the changing rate of hairiness length is the determine criterion, at the same time, the hairiness length of fabric after fuzzing can be used as a reference indicator when the changing rates of hairiness length are almost the same.
