Your development decision
Define direction, loading and rest conditions to compare extension and recovery on actual flannel references.
Two different observations
Extension is the change under a defined load; recovery concerns what happens after that load is removed. A single pull or elastic-fibre declaration cannot establish both. State the garment objective and ask which evidence is relevant.
Keep direction explicit
Mark warp and weft and identify the direction the garment needs. Mechanical extension may arise from construction while elastic fibres are another possibility. Confirm the actual cloth and composition instead of inferring a value from the category.
Use comparable trial conditions
Record sample dimensions, loading or activity, duration and waiting time before reviewing recovery. Use the same method for candidates. If the conditions differ, keep the records separate until a fair comparison can be made.
Connect to garment fit
Knees, seat and sleeves involve pattern ease, seams, lining and wearer activity. Trial the intended construction and photograph the same locations. Garment observations complement a laboratory measurement but have a different scope.
Request formal evidence when needed
Ask for the agreed method, direction, reference tested and acceptance requirement. Retain report date and applicable version. Composition and a general stretch description cannot replace a numerical result for that sample.
Keep the approval limited
Record whether the observation is acceptable for this trial and what remains to discuss. Do not interpret this as a bulk certification. Revise the brief when direction, construction or care changes and recheck affected points.
A practical development example
Two samples have been stretched using different methods. Keep both records, but do not rank their values as if conditions match. Agree a common direction, loading and waiting sequence or request comparable reports. Review the intended garment fit alongside those measured or observed results.
