| titleOfInvention | Improvements in or relating to the dyeing of fibrous materials |
| abstract | Acid wool, substantive and unspecified types of dyes, dyeing with.--The fastness to light of dyeings on fibrous materials, in the pre-treatment, dyeing or finishing of which have been employed substances, not of a dyestuff character, giving rise to cations capable of reducing the surface tension, is improved by an after-treatment with resin or other acids (as such or in the form of their salts) which do not yield precipitates with iron salts but do yield precipitates with the substances giving rise to the said cations. Specified acids are abietic, persulphuric, perboric and ortho-, meta- and pyrophosphoric acids. The use of acids giving rise to anions capable of reducing the surface tension is excluded. In an example, cotton piece goods, dyed with Diamine brown M, dried, impregnated with an aqueous solution of dodecylpyridinium sulphate and again dried, are impregnated with a solution, at room temperature and of pH = 7, of sodium abietate and dried; the dyestuff may be replaced by Direct fast yellow B or FF, Direct brown B, Pluto orange G, Benzopurpurine 4B or Brilliant benzo fast violet 2RL. Specification 435,431 is referred to. |
