Greige Cloth Inspection

Production Verification

Evaluating unprocessed flax yarn arrays on the loom before chemical processing requires rigorous greige cloth inspection. This examination records structural flaws, tension breaks, and reed marks across woven linen bolts, stopping at the boundary of wet finishing operations where dyestuffs permanently alter the visible surface. Inspectors check density against mill standards, distinguishing raw yarn irregularities from mechanical loom faults that require immediate repair.

The resulting document logs fault locations for subsequent trimming or second-grade downgrading before export packaging.

Acceptance Thresholds

Buyers establish specific tolerance limits that supersede internal mill benchmarks to protect commercial value. Rejection occurs when broken pick counts exceed contractual ceilings per linear metre. Technicians measure mass per square metre using cut samples, separating individual fibre defects from yarn spinning inconsistencies that survive the loom.

Commercial agreements dictate whether a bolt receives a primary classification or drops to industrial categories based on total penalty points accumulated during the evaluation.

Remedial Protocol

Defective segments undergo manual mending or physical separation from export shipments to maintain consistent delivery lots. Operators mark damaged zones with colored yarn inserts for easy identification downstream. Mills absorb financial losses resulting from structural failures recorded during the assessment procedure, protecting final garment makers from unexpected material loss during cutting.

Standard Sizing Parameters for Ultrafine Wet Spun Linen Warps

Ultrafine wet spun linen warps demand low-viscosity modified starches with acrylic binders at eight to ten percent size add-on and strict tension limits below one percent.
