10、st Method4.1 Pilling and other changes in surface appearance,such asfuzzing,that occur in normal wear are simulated on a labora-tory testing machine.Pills are caused to form on fabric by arandom rubbing action produced by tumbling specimens in acylindrical test chamber lined with a mildly abrasive m
11、aterial.To form pills with appearance and structure that resemble thoseproduced in actual wear,small amounts of short-length graycotton fiber are added to each test chamber with the specimens.The degree of fabric pilling is evaluated by comparison of thetested specimens with visual standards that ma
12、y be actualfabrics,or photographs of fabrics,showing a range of pillingresistance.The observed resistance to pilling is reported usingan arbitrary rating scale.1This test method is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.60 on Fabri
