Silk is one of the natural protein fibers used widely all over the world. This material has been found to be smooth and shiny, exhibits good mechanical strength, and is biocompatible. It has been shown that fibroin may be dissolved into an aqueous solution, and then formed into a number of different geometrical forms. This paper presented the dissolving process of Vietnam Bombyx mori silk fibroin by an aqueous lithium bromide solution and regenerated it onto cotton fabric via padding method. The fibroin coated cotton fabrics were characterised by scanning electron microscopy (SEM), Fourier transform infrared spectrophotometry (FTIR) and color measurement. The air permeability, wrinkle recovery angle and breaking strength of the fibroin treated fabric were determined as representative physico‐mechanical properties. The analysed results presented no change of the air permeability values, noticeable increase in the wrinkle recovery angle values, and slight improvement of the breaking strength when the fabrics were treated with higher silkfibroin concentration.
