Modification of Sericin with Milk Whey and Properties of the Coated-polyester Fabric

Sericin and milk whey were modified with diisocyanate, toluene-2,4-diisocyanate or hexamethylene diisocyanate as a crosslinking agent, in order to apply for a coating agent of polyester fabrics. The influence of addition of the milk whey was studied. The moisture regain was improved as the ratio of the milk whey to sericin increased at 20°C and 65 %RH. Furthermore, we prepared modified sericin/whey coated-polyester fabrics and studied their washing fastness. After 20 times washing, more than half of the modified sericin/whey remained on the coated fabrics.
