Synthesis and application of polyurethane modified organic silicone wet rubbing fastness improver

Journal Article (Journal Article)

Polyurethane modified organic silicone was successfully prepared from hydroxyl-terminated polyether modified silicone, toluene-2, 4-diisocyanate (TDI), and NaHSO . The chemical structure of the polyurethane modified organic silicone was characterized by FT-IR and H-NMR. The polymer film on the cotton surface was investigated by scanning electron microscopy (SEM) and the results showed that a thin polymer film was successfully formed. The FT-IR of treated cotton fabrics indicated that hydroxyl (OH) of cellulose fiber and isocyanate group (NCO) of the polyurethane modified organic silicone has formed covalent cross-linking. X-ray diffraction (XRD) analysis revealed that the crystalline region of treated cotton fabrics wasn't changed. The wet rubbing fastness of treated cotton fabrics was increased by approximately rating 1 on average. There was little change of DE values for the polyurethane modified organic silicone. The softness was improved significantly. 3 1
