Continuous Dyeing of Piece Goods Using Radio-frequency Heating. Part 1 – Characteristics of Dielectric Heating in Relation to Continuous Dyeing

Current textile uses of dielectric heating are reviewed and the possible application of radio-frequency (r.f.) heating to continuous dyeing of piece goods is discussed. The contribution of typical dyebath components to r.t. power absorption is described in terms of heating rates of aqueous solutions. The effect of electrolyte concentration upon both r.f. power absorption and drying rate of open-width cotton fabric padded with a reactive dye is discussed
