Factors to Predict the Fibrillation Tendency of Lyocell Fibers

Lyocell fibers were treated with a cross-linking agent at various levels of concentration to examine the fibrillation tendency. An optimum concentration was achieved to reduce the fibrillation to a minimum level. The influence of physical parameters on the fibrillation index was also studied. These include birefringence, intrinsic viscosity, and relative crystallinity. The effects of each parameter on the fibrillation index are discussed and a simple mathematical model is proposed to represent the correlations among these parameters
