RESISTOL RD is a bleaching agent designed for use on woolskins which require a ‚snow top’ or ‚brisa’ effect to be imparted to the wool.

RESISTOL RD is effective in bleaching wool dyed with disperse dyestuffs. In order to optimise the effect and degree of bleaching required, it is essential to carefully control the application method and aftertreatment process.

Care and attention to safety measures (gloves, goggles and mask) should be taken when handling RESISTOL RD and its solutions.


Make a stock solution as follows:  (% by weight)

RESISTOL RD         4 -   6 %
Water                         16 - 64 %
Formic acid                20 - 30 %

This stock solution is applied to the dyed wool by brush or pad before steaming for approx. 1 minute. The wool is then subsequently ironed at 160 - 180 °C, in order to optimise the effect.
