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.
Micro Tensile Testing
Instrumental Load
Precision measurement techniques used to determine the mechanical properties of very small or thin textile samples allow for the analysis of single fibres or fine filaments. While standard strength tests use large specimens, micro tensile testing requires specialized equipment capable of applying minute loads with extreme accuracy. This method is essential for developing high performance technical fabrics where individual fibre behaviour dictates the final product strength.
Force Application
Mechanical Stress. The testing machine uses a sensitive load cell to measure the force required to stretch or break a specimen that may be only microns thick. Displacement is tracked using optical sensors or high resolution encoders to calculate the strain.
Specimen Handling
Technical Challenge. Mounting a single fibre for testing involves using a paper frame or specialized grips to avoid damaging the material before the test begins. Even a small nick on the surface of a carbon or aramid filament will cause a premature failure and an incorrect result.
Data Application
Material Science. Results from these tests help engineers model how a yarn will behave during the high speed stresses of the looming process. Understanding the breaking point of individual components leads to more durable and efficient textile structures.
