Antifelting-Coating for Wool from PPD-[Si(OH)₃]₂ Agent via a Sol-Gel Process

Abstract:

A sol type anti-felting agent containing PPD-[Si(OH)₃]₂ synthesized and applied to the wool with pad-dry-cure process. The structure of the prepolymer was characterized by FT-IR spectroscopy and the film transparency and the fiber microstructure were proved though UV-vis analysis and WAXD. The results indicated that the coating could endow a better anti-felting effect with low curing temperature at 120°C and 3 min, the area shrinking rate from13.44% of the original fabric decrease to 2.86% of the treated samples without strength decreased and handle changed stiff seriously, which accord with the IWS Test Method 31 standard.
