Research on Tussah Dye-free Printed Fabric added Tryptophan

摘要

In this experiment, tussah fabric was dye-free printed by using tryptophan-added method. The physical and chemical properties of printed fabrics were tested and measured. The optimal process for tussah fabric dye-free printing tryptophan added has got, which was tryptophan mass fraction of 7.5 %, PHBA of 8 %, HCl of 15 %, HEC of 2.5 %, and H_2O_2 of 2 %. The tussah silk fabric squeegee performed twice and then dried at 80°C for 30 min showed best printing result. Its printing pattern and outline were clear, and it had deep and uniform color. Meanwhile, the breaking strength of the fabric, color fastness and breathability, softness performs were well. What's more, a short process was used, which it's more environment-friendly and more economical.
