Bursting Strength What Improves It and What Damages It
Practical actions that raise or lower Bursting Strength during knitting, dyeing, finishing and garment care.
Actions that help
Correct construction choice and controlled setting improve performance, and they also keep the fabric near above 300 kPa for stretch knits. Working figures for Bursting Strength normally sit around above 300 kPa for stretch knits in mainstream production. Note ISO 13938-1 hydraulic method on the tech pack so nobody tests against an older revision.
Actions that damage it
Excess heat, over-aggressive softener and missing washing-off steps all reduce results. Record elastane content alongside Bursting Strength, because blends shift the measured value. A result outside above 300 kPa for stretch knits usually points to process drift rather than to the fibre itself.
Finishing influence
ISO 13938-1 hydraulic method results shift noticeably after finishing, so retest after the final process rather than before. Keeping reference values for Bursting Strength lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13938-1 hydraulic method, since both affect the reading.
Garment care influence
Home washing temperature and drying method change performance over the first ten cycles. Working figures for Bursting Strength normally sit around above 300 kPa for stretch knits in mainstream production. Note ISO 13938-1 hydraulic method on the tech pack so nobody tests against an older revision.
Summary
Keep process settings documented so repeat orders land inside the agreed range every time. Record elastane content alongside Bursting Strength, because blends shift the measured value. A result outside above 300 kPa for stretch knits usually points to process drift rather than to the fibre itself.
