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.
Linear Density Ktex
Mass Metric
Direct measurement units expressing mass in grams per meter represent heavy textile strands prior to yarn spinning operations. Technical specification sheets record linear density ktex to quantify the thickness of carded tow slivers and draw frame strands. Mill processing cards log input and output sliver weights using kilotex values to calculate mechanical draft requirements.
Standard testing methods dictate conditioning sliver samples at standard atmosphere before gravimetric weighing.
Drafting Measurement
Drafting rollers attenuate heavy sliver assemblies down to smaller tex values suitable for roving insertion. Expressing thick sliver mass in linear density ktex simplifies gear ratio calculations across carding and drawing passages. Deviations in kilotex values disrupt auto-leveller adjustments during sliver preparation.
Process Specification
Wet spinning prep lines utilize strict mass tolerances for heavy sliver feeds to maintain steady material throughput across double-head draw frames. Processing reports express raw flax tow sliver thickness in linear density ktex to establish drafting limits and predict final yarn count capability. Conversion tables in mill laboratories link kilotex measurements directly to resultant yarn tex numbers after drawing and roving stages.
Buyer technical audits inspect draw frame sliver kilotex logs to verify batch uniformity across large delivery consignments. Uncontrolled variations in sliver linear density produce uneven roving strands and cause frequent end breaks during ring spinning.
