Foam is a common problem in textile dyeing and printing, industrial wastewater treatment, pharmaceutical production, pesticide formulation and other chemical processes. It can cause tank overflow, reduce production efficiency and create surface defects on finished products.
This textile silicone defoamer is designed to solve common issues with traditional silicone antifoams, such as emulsion breakage, oil floating and short antifoam duration after dilution. It delivers fast foam knockdown and stable long-term foam suppression, helping production lines run more smoothly.
It remains stable in aqueous systems from room temperature up to 100°C, making it suitable for most textile pretreatment, dyeing, post-dye washing and general chemical processing applications. With low dosage requirements and consistent performance, it is a cost-effective foam control solution for multiple industries.
Silicone defoamer sample for textile dyeing and print
Key Advantages
Fast foam knockdown and lasting antifoam effect
After being added to a foaming system, it quickly reduces the surface tension of the foam film, breaks existing foam and helps suppress new foam formation. This reduces the need for frequent re-dosing.
Good stability, reduced risk of oil floating
The formula is optimized to improve dispersion in aqueous systems. It helps avoid the layering, oil floating and emulsion instability that can occur with some traditional silicone defoamers after dilution.
Heat resistance up to 100°C
Suitable for most textile pretreatment, dyeing, rinsing and washing processes, as well as general chemical production environments where temperature fluctuations occur.
Low dosage, cost-effective performance
Only a small amount is needed to achieve effective foam control. Over time, this helps reduce chemical consumption and production costs.
Wide application range
Besides textile dyeing and printing, it can be used in pharmaceutical processes, pesticide formulations, industrial wastewater treatment and other aqueous systems where stable foam control is required.
Usage Recommendations
It can be added directly to the foaming system, or diluted with water before addition to improve dispersion.
Determine the optimal dosage through a small-scale trial based on actual foaming conditions.
Store in a cool and ventilated place, away from direct sunlight and high temperatures.
If slight sediment appears at the bottom during storage, stir evenly before use. This does not affect performance.
FAQ
Q1: Will this defoamer cause silicone spots on fabrics?
A1: When used within the recommended dosage and when compatibility is confirmed, silicone spots are generally not expected. However, sensitivity to silicone residue can vary by process, especially in light-colored dyeing and printing. A compatibility trial is recommended before bulk use.
Q2: What is the recommended dosage? Can I add more at once?
A2: The typical reference dosage is 0.05‰–0.5‰ of the working solution. The exact amount should be confirmed by trial based on foaming level, temperature and agitation. Adding too much at once is not recommended, as it may reduce compatibility and affect foam control.
Q3: How can I choose the right defoamer for my application?
A3: Please share your application details, including formula type, temperature, pH, foaming behavior and current defoamer dosage. Nanhui can recommend a suitable product or arrange a lab test.
