Side-Chain Amino Silicone Oil
شماره CAS: 63148-62-9
Side-chain amino silicone oil carries aminopropyl or aminoethylaminopropyl groups distributed along the PDMS backbone. This architecture maximizes fiber contact density, delivering superior softness, smoothness, and elasticity to cotton, polyester, and blended fabrics at 0.5–3% on-weight-of-fabric (OWF). Amine value (0.05–1.5 mmol/g) governs softness intensity and yellowing tendency: high-amino grades (>0.5 mmol/g) provide heavy softness for towels and knitwear; low-amino hydrophilic grades (0.05–0.2 mmol/g) suit white and light-colored fabrics where yellowing is unacceptable.
