Effects of ball milling on the structure of cotton

Jan 17, 2019 An early experiment with ball milling reduced the cotton sample to the amorphous state in 30 min (our similar ball milling system is slower) (Forziati et al. 1950 ). Subsequently, Segal et al. ( 1959) developed a crystallinity index (Fig. 1) to indicate the fraction of crystalline material in the sample
