Fungal Damage
Biological breakdown of cellulosics caused by active fungal spores on stored textiles represents a primary physical risk during maritime transport. Cargo mold degradation occurs when packaged linen fabric roll shipments encounter elevated relative humidity inside unventilated ocean containers. Port surveyors detail this condition in damage survey reports to evaluate cargo losses prior to customs clearance.
Affected linen fabrics exhibit localized discoloration, weakened bursting strength and persistent odours that render the goods unmarketable.
Atmospheric Trigger
Temperature fluctuations across ocean transit routes drive moisture evaporation from wooden pallets or cardboard packaging onto cold container walls. The resulting condensation drops onto textile cartons, elevating localized moisture content above critical biological thresholds. Spores dormant within raw flax or finishing starches germinate rapidly under these sealed tropical transit environments.
Tensile degradation accelerates as fungal hyphae secrete cellulase enzymes, hydrolyzing linen polymers into soluble sugars. Laboratory testing confirms the structural loss using mechanical bursting tests across affected fabric sections.
Claim Settlement
Marine insurance policies require immediate notification upon container seal removal to establish liability between carrier and buyer. Evidence of cargo mold degradation invalidates standard quality warranties, forcing cargo underwriters to compensate for total loss or re-conditioning expenses. Mills prevent claims by installing desiccant bags and moisture-barrier liners inside export containers prior to dispatch.
