Silicone Smoothing Agent
CAS Number: 63148-62-9
Silicone smoothing agent is a polydimethylsiloxane-based finishing auxiliary that significantly reduces surface friction on textile fabrics, enabling smooth needle penetration and reducing sewing thread breakage during garment manufacturing. It forms a thin, durable silicone film on fiber surfaces that persists through multiple wash cycles. Suitable for woven and knitted fabrics across cotton, polyester, and blended substrates.
