Hackling Pin Density Effects on Long Flax Sliver Tenacity
Graduated hackling pin density increases flax sliver tenacity by splitting bundles until needle pitch falls below bundle diameter, causing fiber truncation.
Textechno Test Frame
Mechanical Testing
Automated tensile testing instruments measure breaking force and elongation on single fibres or filament bundles. Quality control laboratories employ a Textechno test frame to evaluate flax fibre tenacity and elasticity parameters according to international testing standards. Calibration certificates record load cell accuracy and crosshead speed settings to ensure measurement reproducibility across test series.
Test results are automatically logged in laboratory management systems for batch release authorization.
Automated Measurement
Integrated pneumatic clamps and optical linear density measuring units minimize operator handling errors during single fibre testing. Running high-throughput sample runs on a Textechno test frame generates statistical distribution curves for breaking force and extension at break. Automated data collection speeds up raw flax quality grading.
Tensile Calibration
Spinning mills utilize automated fibre test frames to screen raw flax imports and optimize mechanical drafting settings before carding and hackling operations. Laboratory reports generated by a Textechno test frame document Weibull modulus parameters and mean tenacity for raw bast fibre lots. Comparing strength profiles across different raw material suppliers allows mill engineers to formulate balanced fibre blends for fine wet-spun yarns.
Export quality certificates attach automated tensile test summary sheets to verify raw material compliance with customer strength specifications. Instrument calibration procedures use standardized weight sets to verify load cell performance prior to testing export samples.
