In this paper new pad-dry-bake finishing processes for silk fabric using epoxy resins were
investigated. NaH^PO^ was employed as the buffer for the aikali produced in the course of
processing in order to inhibit the yellowing of the fabric. Padding epoxy resin and a catalyst
to the fabric in a separate bath renders the solution stable and helps to retain the natural
luster and hydrophilicity of the silk. The processes in which epoxy resins, especially TEG and
DEE, would provide significant modifications in resistance to light-yellowing and creaseproofing
are examined and the 'water-spot' problem, which can occur with treated tussah
silk fabric, was substantially eliminated.
