## Abstract Three low‐molecular‐weight polyurethanes (LMWPU) containing various amounts of carboxylic acid were synthesized and applied on the nonwoven fabric for the improvement of water remaining property. The chemical structure of the LMWPUs was confirmed with ^1^H‐NMR and ^13^C‐NMR. The molecul
