The influence of of ter-sulphiding treatment on the properties of viscose adhesive was studied. The decreasings of salt point γ-value, the amount of combined alkali, and joint strength take place during the ripening of viscose. These values are increased by of ter-sulphiding treatment, with the exception of joint strength, to such an extent that non-ripened viscose shows. It is notceable that the joint strength of ripened viscose is not strengthened by of after-sulphiding treatment.
