Textile Sizing Foam Issues? Chemi Tech's Efficient Defoamer Solution Enhances Quality & Efficiency

Excessive foam in textile sizing processes is a common issue that severely impacts quality. Foam causes uneven size penetration, spot formation, and reduced fiber adhesion, affecting subsequent weaving efficiency and final product quality. Traditional defoaming methods often deliver unstable results or interfere with size performance.

Chemi Tech focuses on developing textile auxiliaries, offering a dedicated defoamer series for sizing that addresses these challenges. Their products utilize modified polysiloxane technology to break foam quickly and suppress it persistently, with good compatibility across various sizes without affecting rheology or fabric hand feel.

Solution steps include:

1. Pain point analysis: Identify foaming stage (mixing, sizing, or circulation) and foam type;

2. Product selection: Choose the appropriate model based on size composition (e.g., PVA, starch) and process conditions;

3. Dosage testing: Recommended dosage is 0.1%-0.5%, with optimal ratio determined through small-scale trials;

4. Process integration: Add during size mixing or incorporate via continuous dosing into circulation systems;

5. Effectiveness evaluation: Monitor foam control and check fabric coverage and uniformity.

Case reference: A textile manufacturer using starch-based size experienced severe foam overflow, leading to uneven sizing and frequent. After applying Chemi Tech defoamer KM-12 at 0.3% in the mixing tank, foam was rapidly eliminated, size stability improved, fabric sizing uniformity increased, and停机 cleaning reduced, boosting production efficiency by approximately 15%.

Chemi Tech defoamers help customers achieve stable production and quality enhancement, suitable for cotton, polyester-cotton, blends, and other common fabric sizing processes.
