Continuous Dyeing of Piece Goods Using Radio-frequency Heating. Part 2-Migration Induced During Dyeing
Authors:Stephen M Burkinshaw  William J Marshall
Abstract:Reactive dyes on open-width cotton fabric migrate during drying using r.f energy. This migration, contrary to expectations, is greater than that obtained when using conventional hot-air drying. The extent of dye migration is reduced by an increase in the electrolyte concentration of the dye pad liquor. A possible explanation for r.f.-induced dye migration is proposed.
