Shrinkage & Cut AllowanceTextile Manufacturing
Calculate pattern cut sizes from finished garment specifications or predict final sizes based on directional shrinkage percentages.
Woven goods typically shrink more along the warp (lengthwise) due to loom tension released during wetting. Knitwear shrinks in both directions based on loop relaxation.
To achieve finished garment dimensions of 80x60 cm, your raw layout patterns must be cut at 84.2x61.9 cm to successfully compensate for fiber relaxation.
