Effects of Chitosan with Different Molecular-Weight on the Properties of Cotton

Abstract:

The structure and dyeing properties of the untreated, oxidized, chitosan treated cotton fabric were studied. Due to the deposition of chitosan particles, the cotton surface appeare to be uneven in comparison with that of untreated one as seen from the scanning electron microscopy (SEM); the FT-IR indicate the physical attachment of chitosan to the cotton fabric; high dye exhaustion and color yields (K/S) could be achieved on the chitosan treated cotton than that on the untreated one; with higher molecular-weight of the chitosan, the dyeability mentioned above are superior to that with lower molecular-weight.
