The use of chelating agents in all textile processes is very importa nt as these control the presence of metallic ions.
The application of DABEERSEN chelates eliminates the metal impurities which precipitate during the washing stages. This is achieved even when water with a low hardness is employed, as metal impurities are usually found in fibres.
DABEERSEN chelates should also be employed during the bleaching process as this prevents the break down of bleaching peroxides. This break down reaction is catalysed by manganesium, copper or iron which, if found in the fibre, would cause the appearance stains and even fibre breakage.
Metal ions cause precipitates formation with dyes or colour changes in specific areas of the fabric. The DABEERSEN chelates eliminate these even when complexed with the dyes.
