Quantifying Anti Friction Lubricant Protection Limits for Elastane Cores under High Drag Jet Processing
Sustaining a 1.8 percent ester lubricant film on elastane cores prevents elastomeric rupture when jet nozzle pressure exceeds 2.2 bar.
Synthetic Ester
Lubricating Fluid
Synthesized organic compounds created by reacting alcohols with fatty acids are high-performance lubricating fluids for synthetic fiber extrusion and high-speed yarn spinning. The application of a synthetic ester reduces friction between yarn and metal surfaces during high speed winding. This fluid provides the necessary thermal and mechanical protection for synthetic yarn processing.
Yarn Lubrication
High speed texturizing and spinning machines generate high temperatures that can cause mineral oils to smoke and degrade. Because a synthetic ester has high thermal stability, it remains effective under these conditions without smoking or leaving deposits on the machinery. This clean-running behavior improves yarn quality and reduces maintenance costs.
Biodegradability and Washing
Modern textile mills prefer finishing oils that are environmentally friendly and easy to remove during scouring. The chemical structure of a synthetic ester makes it highly biodegradable and easy to wash out of the fabric before dyeing. This washability prevents uneven dyeing and spot defects.
Fiber Protection
During fiber extrusion, the finish must be applied uniformly to protect the delicate filaments from damage. The synthetic ester distributes evenly on the yarn surface, forming a thin protective film that reduces yarn breakage and static buildup. This mechanical protection is verified by monitoring yarn tension and package build during spinning.
