Silk weighting with organic polymers has taken importance
as finishing operation to improve properties of silk fabrics as
hydrophilicity, crease recovery, dimensional stability, wash
and wear, resistance to abrasion, photoyellowing, and staining.
On the other hand, silk is today more than ever appreciated
for biomedical uses owing to its biocompatibility and the
preparation of antibacterial silk fabrics is a stimulating goal
for researches in this field. It could be attained by grafting
silk with chitosan, a biopolymer known as non-toxic,
biocompatible, biodegradable, and proposed for various
medical and pharmaceutical applications. In fact, it is
recognized that chitosan promotes wound-healing and has
bacteriostatic effect [1,2].
