Weft Knitting Frequently Asked Questions
Short answers to the questions buyers ask most often about Weft Knitting.
What does it mean?
loops formed across the fabric width. Working figures for Weft Knitting normally sit around single jersey, rib, interlock in mainstream production. Note circular or flat machines on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from single jersey, rib, interlock and adjust for the end use of the garment. Record elastane content alongside Weft Knitting, because blends shift the measured value. A result outside single jersey, rib, interlock usually points to process drift rather than to the fibre itself.
How is it tested?
circular or flat machines. Keeping reference values for Weft Knitting lets suppliers quote without extra sampling rounds. Ask for conditioning details together with circular or flat machines, since both affect the reading.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. Working figures for Weft Knitting normally sit around single jersey, rib, interlock in mainstream production. Note circular or flat machines on the tech pack so nobody tests against an older revision.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. Record elastane content alongside Weft Knitting, because blends shift the measured value. A result outside single jersey, rib, interlock usually points to process drift rather than to the fibre itself.
