Coating Weight and Peel Strength on a Laminated Outerwear Shell
Verify coating weight stability and crosslinker kinetics to ensure peel strength exceeds ten Newtons per fifty millimetres after repeated washing cycles.
Strike-through
Fabric Defect
During grey inspection at the finishing mill, a strike-through designates a specific textile fault where dyestuff or printing paste penetrates completely through the fabric substrate from the face side to the reverse side unintentionally. This processing anomaly occurs within roller printing or rotary screen application stages when excessive liquor pressure forces excess chemical colorant past the yarn interlacings of woven constructions. Mill auditors verify this irregularity during light table examination before garment assembly begins.
Chemical Penetration
Excessive viscosity reduction in the liquid dye formulation causes capillary action to draw moisture deeply into the core of continuous filament polyester yarns. Operators monitor nip pressure on padding mangles to prevent surplus liquor from migrating beyond the intended face boundary of knitted goods. When thickener concentration drops below specified thresholds in the recipe, fluid resistance fails and uncontrolled transfer happens across the cross section of the textile.
Inspection Protocol
Quality controllers reject rolls displaying visible pigment transfer on the reverse side during final auditing procedures in the apparel manufacturing plant. Standard illumination boxes reveal tonal irregularities where rogue colorant shows through to the lining side of heavy twill materials. Factories track these occurrences on batch sheets to isolate faulty print runs before cutting operations start.
Yield Loss
Defective yardage exhibiting colour bleed undergoes downgrading or complete scrapping to protect brand standards in finished retail garments. Garment makers calculate financial penalties when rogue dye migration ruins matching interior linings on tailored jackets. Production supervisors adjust machine speeds downward to eliminate pressure spikes during high volume runs of lightweight poplin fabrics.
