Single Jersey Curling and the Finishing Sold as a Fix
Single jersey curl stems from unbalanced yarn torque and asymmetrical loop tension; durable flat performance demands structural yarn balancing rather than temporary resin finishes.
Bursting Strength ISO 13938
Pneumatic Resistance
Testing methodologies evaluate the resistance of woven and knitted fabrics to multidirectional force using a flexible diaphragm. The parameters of bursting strength ISO 13938 provide a standardized process for determining the pressure required to rupture a clamped specimen. This standard is particularly applied to knitted textiles where tensile tests are inappropriate due to fabric stretch.
Diaphragm Mechanism
Pneumatic and hydraulic pressure systems apply a uniform force across the under-surface of the clamped fabric sample. During a bursting strength ISO 13938 evaluation, the textile expands into a dome shape until it fails. The pressure and the height of the dome at the point of rupture are recorded by the test software.
Fabric Elasticity
Elastic recovery properties affect how the material behaves under the dome expansion phase of the test. Under bursting strength ISO 13938, the fabric is subjected to a constant rate of extension or volume increase to ensure that the rupture occurs within a target time frame of twenty seconds. This time-to-burst control prevents the test from running too slowly or too quickly, which would alter the recorded force through fabric creep or dynamic shock.
It allows for reliable benchmarking of heavy-duty industrial apparel fabrics.
Quality Inspection
Garment sourcing contracts specify these bursting limits to guarantee the long-term integrity of activewear and compression garments. Compliance with bursting strength ISO 13938 ensures that the fabric can withstand the stresses of wear and laundering without developing holes at high-tension zones such as elbows or knees. This measurement serves as the final proof of fabric structure.
