We studied the transfer and persistence of the fibers on the blade when a blade penetrated two layers of fabrics. To do this, a cotton plain weave fabric with a thickness of 0.29 mm was covered with a cotton plain weave fabric with thickness of 0.11 mm, 0.18 mm, 0.52 mm, 0.76 mm or 1.50 mm each. The two layers of fabrics were stabbed once with a knife and then evaluated the amount of fiber transferred to the blade. The results showed that fibers from the lower layer fabric were wiped off by the upper layer fabric, leaving less than 50% of the original amount transferred to the blade. The thicker the upper layer fabric, the more fibers from the lower layer fabric were wiped off. However, the amount of upper layer fabric fibers transferred on the blade did not correlate with the thickness of the upper layer fabric.
