Effect of Crosslinking on Hand of the Cellulase Treated Tencel Fabrics

Crosslinks were inserted into Tencel fiber by treating with dimethylol dihydroxyethylene urea (DMDHEU) and their effect on fibrillation and enzymatic hydrolysis was studied. Also, mechanical properties and hand of the DMDHEU/cellulase treated fabrics were compared with those of the cellulase treated fabrics to investigate effect of crosslinking treatment. More fibrils were observed in the cellulase treated samples than the DMDHEU/cellulase treated ones. This indicates that crosslinking controlled fibrillation of Tencel fiber. Cellulase treatment decreased bending and shearing properties largely. Comparing with the cellulase treated fabrics, the DMDHEU/cellulase treated fabrics show more resilient under tensile and shear deformation and less resilient to bending and compressive deformation. The DMDHEU/cellulase treated fabrics were softer, smoother and more resilient than the cellulase treated fabrics.
