Pilling Property

The pilling property of 3 knitted fabric samples, which are made from 32s soybean yarns, 32s cotton yarns and 32s PAN yarns respectively, were tested with nylon brush for 50 revolutions and with fabric for 50 revolutions. The test results indicate that the pilling degree of soybean sample is similar with that of cotton sample and better than that of PAN sample; while the fuzzing fibers of soybean sample are much longer than that of cotton and PAN samples.

In a word, due to the low frictional coefficient, low crimp number and low crimp stability of soybean fiber, the soybean fabric sample is easy to fuzzing but not easy to pilling. According to GB4801.1-84, the pilling property of soybean sample is grade 2, while that of cotton sample is grade 1.5 and PAN sample is grade 1.
