Detecting Short-Staple Flax Blends in Combed Line Sliver
Detect short-staple flax blends in combed line sliver using comb sorter mass arrays and ISO 2370 air permeability tests to stop drafting breaks.
Floating Fiber Control
Drafting Zone Stabilization
The mechanical guidance of short, un-gripped fibers within the drafting zone of a spinning frame prevents the formation of thick and thin yarn defects. In flax spinning mills, floating fiber control refers to this critical guidance system. This mechanism ensures that fibers move at a uniform speed.
Apron Tension Regulation
Dual aprons or control rollers are employed within the draft field to compress the fiber strand and restrict erratic movement. Because flax fibers possess a wide variation in length, shorter fibers tend to float and bunch up, which leads to slubs in the finished yarn. Proper floating fiber control maintains a constant pressure, ensuring that only the fibers gripped by the front delivery rollers are drafted.
This controlled movement directly reduces yarn coefficient of variation values on the final test reports.
Yarn Uniformity Yield
High drafting speed requires finer calibration of the control elements to avoid friction-induced fiber damage. When spinning coarser tow yarns, wear on the leather aprons or rubber rollers degrades the precision of the system. Maintenance teams check the tension and alignment of these elements weekly to maintain consistent quality standards.
The outcome of this routine maintenance is a measurable reduction in loom stoppages during the weaving phase.
