Fabric Defect Assessment
Visual evaluation protocols applied to unfinished woven cloth from flax yarn determine the structural and aesthetic category of the material before wet processing begins. Greige inspection grading operates within Chinese textile facilities as a systematic assessment of unfinished linen cloth exiting the loom room. Inspectors examine the woven surface across illuminated inspection frames to record warp breaks, filling faults and structural irregularities on the batch production sheet.
Raw flax fiber evaluation occurs prior to spinning through staple length measurement and trash content analysis, whereas fabric grading evaluates the integrity of the integrated yarns after loom removal. Mills execute internal quality sorting to maintain consistent yarn tension and prevent mechanical damage during subsequent wet processing stages. Buyer acceptance criteria diverge from mill sorting parameters by establishing strict penalty thresholds for structural flaws that survive final bleaching and dyeing operations.
Surface Parameter Evaluation
Quantitative defect categorization translates visible loom anomalies into numerical penalty points per hundred square meters of unfinished cloth. Chinese manufacturing floors record slubs, foreign matter inclusions and missing threads against standardized point charts during continuous roll examination. Exceeding thirty penalty points per designated inspection unit moves the textile lot out of export classification and into domestic discount channels.
Warp density irregularities alter the absorption capacity of the linen during alkaline scouring and oxygen bleaching stages. Mill operators trace recurring pattern distortions back to specific loom stations to adjust shedding motions before further yardage accumulates on the production floor.
Export Specification Compliance
Finished linen export standards require complete traceability from the initial flax heckling line through final greige roll verification and packing documentation. Export documentation records the final quality score alongside the batch identification number to satisfy international apparel and homeware purchasing contracts. Overseas buyers reject shipments failing to meet specified density and tensile strength requirements regardless of prior mill sorting classifications.
Final packing lists accompany the containerized textiles from the coastal port to international distribution hubs. Rigorous defect grading at the unfinished stage protects downstream processing yields and prevents substandard linen from entering global supply chains.
