Hackling Yield and Wet-Spinning End Breakage in Blended Bast Bales
Optimizing hackling pin density and wet-spinning trough temperature stabilizes draft forces, reducing bast yarn end breakage below fifteen breaks per thousand spindle hours.
Cost per Kilo
Expenditure Base
Unit expense quantification establishes the total monetary outlay required to generate one kilogram of finished flax fiber, spun linen yarn or finished woven greige goods. Financial controllers use cost per kilo across Chinese wet spinning operations to consolidate raw unretted straw procurement, water basin heating utilities, chemical scouring reagents and shop-floor labor into a single production metric. This operational metric tracks unit cost variations across differing yarn counts ranging from coarse wet-spun 14 Nm yarn down to fine 39 Nm apparel yarns.
Financial calculations cease at warehouse receipt before logistics providers apply external container freight and customs tariffs. The mill cost ledger records these cumulative expenditures at the close of every spinning shift.
Allocation Structure
Raw scutched flax fiber and hackled line bundle acquisitions constitute the largest raw material component within overall wet ring spinning expenditures. Processing lower-grade flax into fine count yarns increases machine cycle duration and multiplies comb waste, which raises overall cost per kilo through extended machine running hours and supplementary roving twist insertions. Water heating energy for wet-spinning troughs and effluent processing fees impose variable processing surcharges onto every physical bundle processed across the plant floor.
Highly automated spinning setups balance upfront ring frame capital depreciation against reduced human operator wages per spindle row. Wet spinning mills reconcile spinning yields monthly against raw material issue slips to expose process waste.
Commercial Benchmark
Enterprise cost accounting standards establish internal factory baseline figures, whereas international import buyers rely on cost per kilo to establish export transaction pricing across commercial sales agreements. Export contracts designate delivery terms under Incoterms rules, isolating factory gate expenditure from destination port maritime insurance and transport charges. Mill sales managers benchmark their internal manufacturing outlays against prevailing European flax fiber auction quotes to preserve gross processing margins.
Quality inspectors append the final package yield calculation to the yarn batch shipping invoice before container loading. Sustained unit cost control determines the commercial feasibility of spinning high-count pure linen collections for overseas fabric weavers.
