Tensile Metric Determination in Scutched Long Staple Flax Fibre
Stelometer bundle testing at 3.2 millimeter gauge length with gravimetric tex verification establishes accurate tensile tenacity limits for long staple flax purchasing.
Wet Spinning Count Limit
Yarn Fineness
Maximum yarn fineness achievable during hot-water draft spinning defines the technical capability of a flax processing facility. In the linen industry, wet spinning count limit is the finest yarn size, measured in lea or metric count, that can be spun from a given grade of flax without causing excessive breakages. This threshold is governed by the average length, strength, and parallel alignment of the flax fibers in the roving.
Mills use this limit to assign raw material batches to their appropriate product lines.
Material Boundary
Hot water softens the pectins that bind flax fibers together, allowing them to slide smoothly during the drafting process. If a mill attempts to spin a yarn that exceeds the count limit of the fiber, the fiber bundle becomes too thin and snaps before twisting. This breakage increases waste and leads to weak points in the finished yarn.
High-quality line flax allows for much finer counts than short-fiber tow.
Yarn Spinning
Adherence to this limit ensures that the spinning frames run with minimal interruptions. Attempting to spin beyond this boundary results in low-quality yarn with high hairiness and frequent thin spots. Mill managers carefully balance fiber selection and target count to optimize spinning room productivity.
