Cellulosic-based fabrics, such as viscose, tend to wrinkle and this leads to deterioration of their appearance. In this topic, there are many studies with different chemicals and nowadays DMDHEU derivatives are the most commonly used chemicals for easycare. In this study, the analysis of SEM and FTIR, color difference, breaking and tear strengths, softness and crease resistance angle values of the fabric were measured after two different cross-linkers were applied to viscose woven fabric by impregnation method in different concentrations. The analysis SEM and FTIR support the presence of both chemicals on the viscose surface. After treatments, the formation of formaldehyde is below the limit values, and the loses in physical properties and stiffness (handle) are in the acceptable levels. The best results were obtained with the modified dihydroxy ethylene urea chemical when tensile strength, modulus, and tear strength values are taken into consideration. Bending stiffness and bending modulus of fabrics increase with increasing concentration of chemicals and the best wrinkle values were obtained in the highest concentration. It is seen that the color difference in the fabrics is high and the color difference continues to be a big problem when compared with the other negative effects after the treatments. The results showed that both chemical applications were positive effective on the wrinkle properties of the viscose fabric, and also the use of softeners in recipes especially improved on the fabric handle and mechanical properties of the viscose fabric. In summary, dihydroxy ethylene urea derivatives have an effective chemical group for wrinkle-free finishing treatments.
