Micro-Emulsion Silicone Polymers
Micro-Emulsion Silicone Polymers are silicone-based finishing agents supplied as transparent micro-emulsions with particle sizes typically below 50 nanometers. The small particle size allows deep penetration into the fiber structure rather than surface deposition only, producing a soft internal hand feel, improved elasticity, and reduced friction between yarns. Because the emulsion is transparent and mechanically stable, it is suitable for continuous pad application and exhaust processes without the breaking and oil-spotting risk associated with macro-emulsions. The range includes amino-functional, hydrophilic, and reactive silicone systems, with APEO-free and formaldehyde-free options that support OEKO-TEX, ISO 14001, and ISO 45001 compliance requirements.
Company Strengths
Jiangyin Huanan New Material Technology Co., Ltd. is located in Jiangyin City, Jiangsu Province, China, and has produced textile auxiliaries continuously since 1984. Research, development, production, and sales are handled in house across two production plants with a combined annual capacity of 60,000 tons. The silicone range is developed alongside pre-treatment, post-treatment, and dyeing auxiliaries so that silicone finishing can be matched with the rest of the process from one supply source.
In-House Silicone Development
Micro-emulsion silicone polymers are developed and produced in house, which allows adjustment of particle size, active content, and functional group selection based on the target hand feel and the fiber blend being processed.
Coordinated Auxiliary Portfolio
Silicone softeners are supplied together with moisture-wicking finishing agents, antistatic agents, fixing agents, stiffening agents, and fastness enhancers, so mills can build a complete finishing system from a single source and reduce compatibility risk.
Environmental Compliance
APEO-free and formaldehyde-free formulations are available across the silicone range. Products are designed to support OEKO-TEX, ISO 14001, and ISO 45001 requirements and restricted substance lists for export markets.
Batch Consistency
Production control targets consistent particle size distribution and active content between batches, which supports stable hand feel and shade results over long production runs and repeat orders.
Technical Adjustment Service
Formulation adjustment based on fiber type, machine configuration, water quality, and target performance. Same-bath compatibility pre-testing guidance for silicone combined with other finishing agents.
Export-Oriented Supply
Packaging and documentation oriented toward international buyers, including regions with specific environmental and restricted substance requirements.

Processing Recommendations
Pad Application
Dosage 10 to 50 g/L. Wet pick-up 60 to 80 percent. Dry at 100 to 120 degrees Celsius. Cure at 150 to 160 degrees Celsius for 1 to 3 minutes depending on the grade.
Exhaust Application
Dosage 1 to 5 percent owf. pH 5.0 to 6.5. Run at 40 to 60 degrees Celsius for 20 to 30 minutes. Drain and dry. Rinsing depends on the specific grade and subsequent process.
Dilution
Pre-dilute with cold to warm water under gentle agitation. Add the product to the water rather than water to the product. Use deionized or soft water where required.
Compatibility
Pre-test with fixing agents, repellents, and stiffening agents in the same bath. Charge nature varies by grade and must be matched to the rest of the finishing system.
Frequently Asked Questions
Micro-emulsion silicone polymers have a particle size typically below 50 nanometers and appear transparent, while macro-emulsions have larger particles and appear milky white. The smaller particle size allows deeper penetration into the fiber structure, which produces a softer internal hand feel rather than a surface coating. Micro-emulsions are also less prone to breaking and causing oil spots during pad application.
Yellowing depends on the functional group and the curing conditions. Standard amino-functional silicones can yellow on white shades if the curing temperature is excessive or if the bath pH is alkaline. Selected grades are formulated for reduced yellowing. To control yellowing risk, maintain bath pH between 5.0 and 6.5, control curing temperature, and select a grade specified for white and light shades.
Standard amino-functional silicone polymers form a hydrophobic layer on the fiber surface and can reduce water absorbency. Hydrophilic silicone grades are formulated to provide softness while maintaining absorbency. For applications such as sportswear, toweling, and underwear where both softness and moisture management are required, a hydrophilic grade should be selected and absorbency pre-tested.
Compatibility depends on the charge nature of both products. Weakly cationic and non-ionic silicone grades are generally compatible with many fixing agents, but direct mixing can cause precipitation in some combinations. A two-bath process is preferred where compatibility is uncertain. Pre-testing in the actual bath combination is recommended before bulk production.
Oil spots are usually caused by emulsion breaking, which can result from excessive shear, incompatible charge combinations, high electrolyte content, or pH outside the recommended range. Micro-emulsion grades are more resistant to breaking than macro-emulsions. To avoid spotting, pre-dilute correctly, control bath pH, pre-test compatibility with other auxiliaries, and avoid excessive pump shear in circulation systems.
Store in a cool, dry area away from direct sunlight. Protect from freezing below 5 degrees Celsius. If the product freezes, thaw slowly at room temperature and stir gently before use. Avoid high shear agitation during stirring. Keep containers closed when not in use to prevent contamination. Shelf life is 12 months in the original unopened container under recommended conditions.
Yes. Micro-emulsion grades are mechanically stable within the recommended shear range and are suitable for inline dosing with flow meters and injection systems. Viscosity and pump compatibility should be confirmed for the specific grade. Avoid excessive pump speed, which can introduce high shear and affect emulsion stability.
Notes on Use and Storage
| Freeze protection | Do not store below 5 degrees Celsius. Thaw slowly and stir gently if frozen. |
| Shear control | Avoid excessive pump speed and high shear agitation to protect emulsion stability. |
| Dilution order | Add product to water under gentle agitation, not water to product. |
| pH control | Maintain bath pH between 5.0 and 6.5 to reduce yellowing and emulsion breaking risk. |
| Contamination | Keep containers closed. Avoid contact with incompatible charge types. |
