STUDY ON THE SILK FINISHING PROCESS WITH EPOXY-RESINS

In this paper new pad-dry-bake finishing processes for silk fabric usi ng epoxy resins were investigated. NaH2PO4 was employed as the buffer for the alkali produced in the course of processing in order to inhibi t the yellowing of the fabric. Padding epoxy resin and a catalyst to t he fabric in a separate bath renders the solution stable and helps to retain the natural luster and hydrophilicity of the silk. The processe s in which epoxy resins, especially TEG and DEE, would provide signifi cant modifications in resistance to light-yellowing and crease-proofin g are examined and the 'water-spot' problem, which can occur with trea ted tussah silk fabric, was substantially eliminated.
