All Grades (by chemistry class)
Amino Silicone Softeners — Side-Chain Type(3)
The premium choice for fabric softening. Side-chain amino groups adsorb strongly onto cotton (via cellulose hydroxyl–amine interaction) and polyester (via electrostatic attraction), anchoring the PDMS chain flat on the fibre surface. This creates a dense, oriented silicone film that imparts: silky smooth handle, reduced inter-fibre friction (sewing ease, anti-pilling), and controlled drape stiffness. High-AEW grades (8,000–15,000 g/mol) minimise yellowing on white or bright fabrics. For durable finishes, micro-emulsified amino silicone (particle size < 100 nm) penetrates into the fibre structure better than standard macro-emulsion.

Side-Chain Amino Silicone Oil
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.

عرض التفاصيل ←PDMS Emulsions for Textile Lubricity & Anti-Pilling(1)
Plain PDMS (no functional groups) applied as 30–40% aqueous emulsion. Does not adsorb as strongly as amino silicone, but provides excellent lubricity (reduces needle penetration force in sewing, reduces warp breakage in weaving) and anti-pilling (reduces fibre-on-fibre friction). Used where softness enhancement is secondary to lubrication, or as a component in multi-silicone finishing baths. The 30% grade at 0.3–0.5% add-on is the most widely used concentration in finishing.
Anti-Wrinkle & Waterproofing Silicone Finishes(0)
Crosslinkable silicone finishes for functional performance beyond hand-feel: (1) Anti-wrinkle agents — based on silicone polyol or amino-functional polysiloxane crosslinked in situ with blocked isocyanate or glyoxal, reducing cotton crease recovery angle loss in repeated washing; (2) Silicone waterproofing emulsions — non-fluorinated DWR (durable water repellency) systems based on polymethylhydrosiloxane (PMHS) crosslinked with a tin or titanium catalyst, or silane-based DWR; perform to Spray Rating 80–100 after 10–20 machine washes. These functional finishes are applied in pad-dry-cure sequences and require cure temperatures of 140–170°C for crosslink completion.
Frequently Asked Questions
▶What concentration should I use in the padding bath for amino silicone softener?
Typical padding bath: 20–50 g/L of amino silicone micro-emulsion (equivalent to 0.5–1.0% solid add-on on fabric weight at 70–80% wet pick-up). Start at 30 g/L and adjust based on hand-feel panel evaluation.

▶How do I combine silicone softener with a stiffener or anti-static agent in the same bath?
Check ionic compatibility first: non-ionic amino silicone (or micro-emulsion) can be combined with most non-ionic and anionic auxiliaries. Cationic amino silicone cannot be mixed with anionic auxiliaries — they flocculate. Always do a jar test at 5× bath concentration before committing to the production trial.

▶What is fluorine-free waterproofing, and how does silicone DWR compare to C6 fluorocarbon?
Fluorine-free waterproofing (silicone-based or wax-based) is replacing C8/C6 fluorocarbon DWR due to environmental regulations (PFAS restrictions). Silicone DWR achieves Spray Rating 80–90 initially but loses faster than C6 in wash durability — around 50–70% performance after 20 washes vs. C6's 70–80%.
