Study on sericin coated finishing of cotton fabric and its properties

In order to develop high quality and functional cotton product,sericin with negative charge and chitosan derivative with positively charged were reacted to form a new micro particles with viscose effect in aqueous solution.Then sericin was further fixed on cotton fabric by polyacrylic acid crosslinking agent reacted at low temperature.The wearability,surface morphology and structure of cotton fabrics were tested before and after sericin coating.The results showed that sericin was uniformly coated on the surface of cotton fabric.The coating had good washing durability.The dissolve loss rate of sericin coated on fabric is about 0.21% after five washing cycles.The moisture absorption,thermal insulation,moisture permeability and biocidal property of sericin coated cotton fabric increased,but the air permeability showed no significant change.The sericin coated cotton fabric was a new kind of top grade cotton products.
