Quality Standard
Industrial linen production requires a systematic evaluation of parallelized long fibres to determine their suitability for fine yarn counts. Through hackled flax grading, mills categorize processed flax line by its length, strength, cleanliness, and colour. This process divides the raw material into distinct batches after the combing and combing-like actions have removed short tow fibres and residual straw.
Classification Procedure
Experienced assessors inspect each lot manually by lifting bundles to test their tensile resistance and flexibility. The hackled flax grading protocol assigns numerical or alphabetical values based on how well the fibres split into fine strands without snapping. In Chinese mills, these grades align with standardized buyer benchmarks that dictate the spinning limits of the yarn.
Bundles with poor parallelization are relegated to coarser yarn production.
Commercial Value
Flax spinners use these grades to formulate the precise blending recipes required for high-speed automated ring spinning. Consistency in this assessment protects the spinning mill from unexpected drafting failures and yarn thin-places. High grades fetch a premium because they allow the spinning of fine, uniform linen yarns with minimal loom stoppages during weaving.
When the grading process is inaccurate, it leads to frequent yarn breaks that compromise both the productivity of the mill and the final fabric appearance. Consequently, spinning plants maintain strict control over this stage, auditing the graders regularly against physical master samples.
