Definitions

  • casein wool which otherwise should in practice he the best. It has now been found that if casein wool is subjected to a preliminary treatment with diluted acid solutions, its behaviour with respect to chrome colours becomes analogous to that of natural wool.
  • the treatment may be carried out on the casein wool fiber as well as directly on the mixed fiber of casein and natural wool.
  • Example 1 The mixture of casein and natural wool is treated during minutes with abath containing 1-2 c. c. m.-'phosphoric acid per litre,
  • the bath is cooled and after addition. of 1% sodium or potassium bichromate it is again brought to boil for about 20-30 minutes. At the end the material is washed.
  • the preliminary treatment with acid may be a first step of dyeing according to the above exmerit.
  • on both the fiber of casein casein wool and natural wool tor dyeing with chrome dyes which comprises ..treating these I mixed fibers with a dilute aqueous solution having an acid reaction due to the presence of phosphoric acid.
