Greige Fabric Defect Inspection Standards across Sectional Warping Batch Runs
Sectional warping batch inspection requires matching drum cone angles to yarn build and scoring periodic band faults under strict four point penalty thresholds.
End Break
Spinning Frequency
Yarn consistency depends on the density of fibre discontinuities occurring during high speed ring frame rotation. An end break marks the point where the strand separates under tension, forcing the operator or automated system to rejoin the severed segments. This event interrupts the continuous output of the machine and requires immediate mechanical correction to prevent the production of knots or thick spots in the finished yarn.
Maintenance logs track the frequency of these occurrences per hundred spindle hours to quantify the stability of the spinning operation. Mill production managers use these records to adjust traveler weight or frame speed when excessive failures compromise the physical properties of the yarn.
Material Tolerance
Strict quality control protocols define the acceptable threshold for these breaks before a lot requires a downgrade in grade or a full rejection. Buyers define their limits based on the intended application of the linen, as warp yarns face higher stress on the loom and require fewer joints than weft yarns. Mills establish internal baseline data during trial runs to identify the limits of the raw flax supply in relation to local humidity and ambient temperature.
When the rate of failure exceeds the contracted limit, the mill must implement corrective actions such as reducing the twist per inch or recalibrating the tension controls.
Acceptance Protocol
Final export documentation includes the count of splice points resulting from each end break found during the post-spinning inspection. Shipping manifests identify the number of joints per kilometer of fabric to ensure the material meets the requirements of the final garment or household textile manufacturer. These records provide a verifiable audit trail for traceability from the spinning phase through to the weaving floor.
High tension loads during the later stages of finishing confirm that only stable, well-joined strands remain in the finished bolt of cloth.
