Polymer Chemistry
Group of synthetic polymers used as high performance lubricants and heat transfer fluids resists thermal degradation. Formulations containing polyalkylene glycol provide superior thermal stability and low volatility during synthetic fiber extrusion. These polymers are often selected for their ability to wash off easily in aqueous scours.
Lubrication System
Fiber producers apply polyalkylene glycol to filaments to reduce friction against metal guides and ceramic heaters. This polymer prevents the buildup of static electricity which causes yarn breakage.
Processing Advantage
Ease of removal in the dye house makes this chemistry preferable to mineral oils for delicate fabrics. Because polyalkylene glycol dissolves readily in water, mills use lower temperatures and fewer detergents during the preparation stage. This clean removal ensures that subsequent dyeing or finishing processes are not hindered by residual oily films on the fiber surface.
Surface Safety
Interaction between the lubricant and the fiber polymer must not lead to swelling or degradation of the yarn structure. Testing confirms that polyalkylene glycol is compatible with common elastomers and plastics used in garment components. Use of this polymer reduces the risk of stress cracking in sensitive synthetic materials.
Laboratory analysis verifies the concentration of the polymer on the fiber to ensure performance without excessive cost. Verification of residual levels prevents contamination of the dye bath.
