Characterizing Fuzz in Nonwoven Fabrics

The present work describes a cylindrical lighting system and its applications for objectively assessing the presence of fuzz in nonwovens. This cylindrical lighting system was designed to allow easy isolation and measurement of fuzz by illuminating the fuzz and suppressing the background. Images acquired under different conditions showcase the need for and the utility of a cylindrical lighting system. The characteristics of fuzz in nonwoven fabrics are extensively explored as a function of different bonding temperatures, abrasion cycles, and the direction of the abrasion force.
