10、advisable that zippers be closed when items inwhich they are installed are being laundered or dry cleaned.6.Shrinkage6.1 Excessive differential shrinkage between the zipper andthe material into which it is installed can impair item appear-ance and the functioning of the zipper.To avoid problems,zipp
