Standard Operating Inspection Protocol for Four Point Greige Scoring
ASTM D5430 four-point scoring normalises greige defects per 100 square yards, capping penalties at four points per yard to decide lot acceptance.
Roll Splicing
Joining Protocol
Mechanical bonding creates a continuous feed of linen fabric rolls during the finishing stage by joining the end of one web to the leading edge of a subsequent unit. Roll splicing preserves line speed by allowing textile machines to operate without pause while new material enters the coating or dyeing path. Technicians apply pressure-sensitive adhesive tapes or heat-activated resins across the overlap to prevent web separation under high tension.
This technique maintains alignment between fabric widths to reduce waste during long production runs in finishing departments. Workers verify each connection point against mill tension requirements to ensure the bond withstands the force of heavy rollers. Adherence to strict overlay widths determines if a connection survives the mechanical pull or creates a bulge that ruins surface quality.
Bond Performance
Integrity tests quantify how the union holds when pulled through the heat set chamber. Examiners apply constant weight to the overlap area until the material snaps or the adhesive layer delaminates from the linen fibres. A strong joint resists creeping under the thermal load found in drying ovens.
Proper execution keeps the fabric flat so sensors do not trigger emergency stops. Operators observe the joint as it passes rollers to ensure no loose threads snag on internal machinery parts. Any irregularity in the physical profile causes an immediate rejection of the affected section of the piece.
Mill inspectors mark the location of every join on the production log so final cutters can remove the damaged area before shipping. High quality joints allow the entire bolt to remain saleable without reducing the yardage during the final audit.
Material Compliance
Specifications for trade acceptance dictate that a finished roll may contain a maximum of two such links for a standard length of cloth. Professional buyers check these points during quality assurance reviews to ensure that factory joins do not interfere with downstream garment production. A connection that fails to maintain the correct grain alignment or produces an uneven thickness results in a deduction from the contract grade of the fabric.
Textile mills document the frequency of these events in their periodic performance reports to justify output consistency. Each join remains a permanent indicator of the fabrication efficiency achieved during the finishing sequence.
