A method for preparing a novel compound, i.e. a resinous material, characterized in that an epoxy compound is allowed to react with ammonium salt or a metal salt (for example, lithium salt, sodium salt, potassium salt, magnesium salt, etc.) of polyglutamic acid. The resulting reaction product is useful in a method for treating shaped materials especially polyester textiles. In this method the shaped materials are treated with the novel resinous material to improve the appearance and handling characteristics thereof. A process for providing a wooly finish on polyester textiles is characterized by treating textiles (including polyester knittings and mixed spun fabrics or knittings or mixed woven fabrics or knittings) in a bath of an emulsified mixed solution of an epoxy compound and a metal salt of polyglutamic acid containing a catalyst, and carrying out a heat-treatment of the resulted textiles after pre-drying.
A novel resinous material which is obtained by reacting an epoxy compound which has at least two 1,2-epoxy groups with a salt selected from the group consisting of ammonium, lithium, sodium, potassium and magnesium salts of polyglutamic acid, said salt being water-soluble and having a molecular weight of 2,000 to 500,000.
A novel resinous material which is obtained by a method comprising the steps of:
