Pigments are attached to textiles by adhesives, which leads to the instability of painted textiles during wet cleaning. The feasibility, effect and safety of using cyclododecane as a coating and reinforcement material for painted textile during wet cleaning is studied. The orthogonal tests showed that the best result was obtained by brushing once both sides of the painted area with cyclododecane heated to 62℃. The relationship between environmental factors and cyclododecane sublimation speed was also investigated.
