Achieving the optimal results from silicone softeners in textile finishing requires a thorough understanding of application techniques, dosage, and process parameters. NINGBO INNO PHARMCHEM CO.,LTD., a trusted manufacturer and supplier of textile auxiliaries, provides this practical guide to help you maximize the benefits of our advanced silicone softeners. We offer expert advice to ensure you can effectively buy and use our products for superior fabric finishes.

Dosage: The recommended dosage for silicone softeners can vary depending on the specific product, fabric type, and desired finish. Typically, dosages range from 0.5% to 10% (o.w.f. - on weight of fiber) for dipping methods, and 20-50 g/L for padding methods. Always consult the product's Technical Data Sheet (TDS) for precise recommendations. Overuse can lead to greasy fabrics or reduced breathability, so precise measurement is key.

Application Methods:

  1. Padding Method: This is a common method for continuous processing. Fabrics are passed through a trough containing the diluted softener emulsion, then squeezed through rollers to ensure even pickup (typically 65-90%). The fabric is then dried and cured at elevated temperatures.
  2. Dipping Method: Used for batch processing, fabrics are immersed in a bath containing the softener emulsion at a specific liquor ratio (e.g., 1:10 to 1:15) and temperature (e.g., 30-40°C) for a set duration (e.g., 20-30 minutes).

Process Parameters:

  • pH: The optimal pH for most silicone softener applications is slightly acidic, typically between 5.0 and 7.0. Maintaining the correct pH ensures emulsion stability and proper interaction with the fabric fibers. Using acetic acid to adjust the pH is a common practice.
  • Temperature: Curing temperatures after application typically range from 130°C to 170°C, depending on the specific silicone chemistry and desired crosslinking.
  • Compatibility: Always test compatibility with other auxiliaries (e.g., resins, fixing agents) in the finishing bath before large-scale application.
