Patent abstract
A method for restoring bulkiness of nonwoven fabric which contains crimped thermoplastic fiber and is in a roll form is disclosed. The method comprises unwinding the nonwoven fabric from the stock roll, and blowing hot air to the unwound nonwoven fabric by a through-air technique to make the nonwoven fabric increase in bulkiness. The hot air is heated at a temperature lower than the melting point of the thermoplastic fiber and not lower than a temperature lower than that melting point by about 50° C., and is blown for about 0.05 to 3 seconds.
