Abstract
The process for etching mono-filaments before metallising by chemical redn. of metal salt solns., with which they are treated, consistsa of (a) washing the fibre in an acid degreasing bath (b) washing in running water (c) treatment with a soln. contg. 50% hydroxyl ions from soln. or generated chemically, e.g. caustic soda or potash solns., at 65-100 deg.C dependent on the dwell time and the mono-filament diameter and (d) energetic washing in running water and de-mineralising.
