The results of a refractometric study of the formation of intermolecular hydrogen‐bond complexes in water between aromatic compounds, including sulphonated dyes, and a variety of other reagents, including casein, used as models of fibres, are interpreted as an indication of the nature of possible hydrogen‐bond complexes between dyes and fibres. Some conclusions are— ( a ) Non‐ionic polar groups in dyes and other aromatic compounds, whether sulphonated or not, can form intermolecular hydrogen‐bond complexes in water with a variety of organic compounds. ( b ) Hydrogen‐bond formation between dyes and fibres in presence of water appears to be possible with protein fibres, nylon, cellulose acetates, Terylene, and acrylonitrile fibres, but is less likely to occur with cellulosic fibres. Suggestions are made regarding the nature and the position of the dye–fibre bonds.
