Effects of ball milling on the structure of cotton ...
2019-1-17 Ball milling for 15 min broke down the fibers, lowering the sample birefringence as well as the average size of fibers. With longer milling time, the fiber shape disappeared for BMC-45 and BMC-120 (average sizes were 47 μm and 23 μm, respectively), indicating that the extended ball milling effectively broke the WMC fibers into smaller particles.
