What needs to be clarified
Examine dimensional and shape changes, distinguishing knit compaction from drying deformation against the care label and controlled measurements at selected locations.
Materials to prepare
- Jumper with composition and care labels, without further treatment
- Original measurements or an unwashed comparable garment of the same size
- Washing, spinning, detergent and drying records
What to compare
After agreed conditioning, measure length, width and sleeves without stretching; record stitch density and deformation areas. Compare identical positions and reference points. Commission controlled care of the comparison sample separately, documenting every stage; do not automatically transfer results to a garment with unknown treatment and wear history.
Possible outcome of the analysis
An opinion may map measurements and deformation, assess consistency with care conditions and identify data needed to distinguish remaining technical explanations for the shape change.
Limits of the conclusions
Another size cannot reconstruct original dimensions. Further steaming can alter evidence; without drying information, the whole change cannot be attributed solely to wash temperature or yarn properties.
