Colour Measurement in the Hungarian Textile Industry — Research and Application

Abstract

Presented at the 13th Congress of the International Federation of Associations of Textile Chemists and Colourists in London on 21 September 1984.The Colour Measurement and Recipe Formulation Centre was opened some years ago to help dyehouses in the Hungarian textile industry. The work of the Centre and research conducted at various other institutions are discussed in this article. The main topics of research include linear approximations in colour calculations, statistical treatment of colour measurement data, the repeatability of textile dyeing, comparison of different methods for expressing the dyeing strength of dyestuffs, application of instrumental measurement in fastness evaluation, comparison of colour‐difference formulae in establishing tolerances and in colour sorting, and the effect of mercerisation on the colour of dyed cotton.
