Cotton was etched in 15% NaOH solution at $90^{circ}C$ for 15 min in order to give good wettability. Then it was catalyzed and accelerated by using $PdC1_2$-$SnCl_2$ solution and 10% $_2$$SO_4$, respectively. Uniform deposits on cotton were obtained when it was electroless copper deposited in pH 10.5 solution at 3$0^{circ}C$ and Ni-Fe-P deposited in solutions of pH 11 at$ 75^{circ}C$. The latter deposit has a chemical composition similar to that of permalloy.
