Textile Silicone Emulsion Selection Guide | MESIL® TX Series

Substrate-Driven Selection Logic

Stop guessing. Use the definitive conditional logic below to match your substrate material to the specific MESIL® formulation.

Your target substrate is Natural Cotton (CO), Polyester (PES), Viscose (CV), or Corduroy.

Select TX 6461 E (~60% NV) or TX 6401 E (~40% NV). These reactive amino-modified macro-emulsions penetrate cellulose fibers effectively, imparting a drapable, elastic, and slippery hand.

You are formulating a premium softener specifically engineered for Cotton/PES blends requiring wash-and-wear durability.

Select TX 6052 E (~40% NV). It dramatically improves sewability and tear strength while reducing abrasion loss, providing permanent effects even without the addition of a crosslinking catalyst.

You are treating Synthetic Fibers (Nylon and PES) requiring extreme surface slipperiness and a color-deepening effect.

Select TX 6251 E (~50% NV). This formulation offers excellent rebounce and a slightly hydrophobic nature tailored for synthetic woven and knitted fabrics.

Your application is strictly Industrial Mould Release, Extruded Rubber Lubrication, or Yarn Manufacture.

Select TX 6350 E (~63% NV). This is a non-ionic polydimethylsiloxane emulsion boasting emulsion stability up to 50°C and excellent dilution stability (down to 2% in water) for extreme mechanical environments.

You require a highly safe, low-concentration (30%) formulation for Knitware or Personal Care products (hair styling, bath).

Select TX 5103 E (~30% NV). Its light blue translucent appearance and delicate amino-modified structure make it the safest choice for leave-in applications and exhaust method processing.

Active Content & Technical Parameter Matrix

Data drives decisions. Compare the non-volatile content (solid content), pH, and appearance to ensure compatibility with your existing chemical systems.

Process Integration & Application Standards

Padding Process Integration

For industrial textile finishing, the padding process is standard. Grades like TX 6461 E, TX 6401 E, and TX 6052 E are optimized strictly for padding. The typical recipe demands 5-30 g/l of the emulsion. Liquor pick-up should be maintained at about 50%, followed by drying at approximately 130°C.

Exhaust Method Capabilities

Not all emulsions survive the high shear of the exhaust method. However, TX 5103 E is specifically engineered to handle it. A dosage of 1~3% (relative to the weight of goods) is adequate. Processing should be strictly controlled at 40~50℃ for 15-20 minutes, ensuring the liquor pH does not exceed 5.0.

System Loop: Expert Selection Q&A

Resolving the final technical barriers before formulation:

Q: How does the silicone emulsion interact with other finishing agents or resins?

A: Due to the non-ionic emulsification system across the MESIL® TX series, compatibility is generally excellent. However, if used alongside crosslinking agents, the silicone emulsion should always be added last in diluted form. Always perform a compatibility test first.

Q: What are the absolute limits for storage and packaging logistics?

A: All grades are delivered globally in 190 kg drums. The storage location temperature must strictly not exceed 35°C. Under these conditions in tightly closed original containers, the shelf life is guaranteed for 12 months from the production date.

Q: Are catalysts absolutely necessary to achieve permanent softening effects?

A: No. Advanced formulations like TX 6052 E and TX 5103 E are engineered to deliver permanent, wash-resistant effects even without the addition of a catalyst.
