Deterioration of polyamide 6 fabrics upon exposure to ultraviolet radiation for a long time is an acute dilemma. Imparting ultraviolet protection to polyamide fabrics is of prime importance from the performance and economic point ofviews. In this investigation, polyamide 6 fabrics were modified with an environmentally friendly product (sericin) in presenceor absence of crosslinking agents; namely citric acid or epichlorohydrin using pad-dry-cure technique. Topographicalinvestigation of the used sericin powder was conducted using transmission electron microscopy (TEM). The morphologicalstructure of treated as well as untreated fabrics was investigated using high resolution field emission scanning electronmicroscope (FE-SEM). The alteration in some physico-mechanical characteristics of the treated polyamide 6 fabrics; Viz. bending stiffness, burst test, degree of yellowness, and moisture regain were assessed. The treated polyamide fabrics weredyed with acid and reactive dyestuffs. The colour strength and washing fastness for dyed fabrics with both acid and reactivedyes were assessed. The photo-protection against UV light of the said fabrics were evaluated. The treated fabric exhibitedexcellent UV protection without significant discrepancy in their inherent physico-mechanical properties.
