Abstract:

In this work, a carbon dioxide laser was used for the color-fading treatment of cotton/kapok denim fabrics. The results were analysed thoroughly and compared with those of cotton denim fabric and PET denim fabric. Results showed that with laser treatment, the fabrics were colour-faded, and the K/S value of cotton/kapok fabric was reduced, while there was little change in the thickness and permeability. Because the internal air of the kapok fiber was squeezed out, the tensile strength of the fabric was decreased. The influence of laser power and speed on the kapok denim was also investigated. With an increase in the laser power and decrease in the speed, both the K/S values and strength decreased significantly. However, the changes were negligible for the thickness and permeability of the cotton/kapok denim fabric. It is therefore concluded that kapok is a good denim fabric material for the laser process.
