ABSTRACT:
An agent for improving the color fastness of dyed cotton fibers and textiles to chlorinated water which comprises a specific diamine compound. The combination of the diamine and hydrolyzable tannin further increases the color fastness to chlorinated water. The tannin can be more strongly fixed to the fibers by further treating with a metal salt, whereby an excellent color fastness to chlorinated water can be maintained for a prolonged period of time.
