Abstract: The linen fabric was modified via UV photografting of acrylic acid. The wearability of photografted linen fabric was studied. The results showed large improvement on dye uptake and color depth, enhancement on tensile properties and stiffness, decrease in air permeability. With the grafting ratio increasing, the dyeuptake, color difference and stiffness increased,but the air permeability decreased. At the grafting ratio of 8%, good dyeing effect could be achieved.
