Definitions

  • the present invention relates to an improved process for desizing and bleaching fabrics in a single operation in a bath based on hydrogen peroxide.
  • the pH of the desizing-bleaching bath is more or less modified during the treatment, which leads to significant differences in the bleaching and desizing results.
  • the present invention fulfills such an object and provides an improved process for desizing - simultaneous bleaching of tissues in a bath comprising hydrogen peroxide, a sequestering agent, an amylase and a surfactant, characterized in that add to said bath a buffer consisting of sodium tetraborate decahydrate in an amount such that the pH of the bath is equal to 9.8.
  • a desizing-bleaching bath which can be used according to the invention can for example comprise: and a buffer consisting of sodium tetraborate decahydrate in a determined amount to fix the pH of the bath at 9.8 (or approximately 10 g of sodium tetraborate decahydrate per 1 bath).
  • the adoption of the desizing - simultaneous bleaching process of the present invention allows significant savings in water, steam, labor and investment and leads to desizing - bleaching results greater than those obtained without buffer or in using another buffer allowing the pH of the bath to be fixed at an equivalent value.
  • sodium tetraborate decahydrate as a buffer avoids working in a strongly alkaline medium and thus protects the treated fabric against the formation of "breaks" during deposition in folds.
  • the treatment is followed by washing at 90-95 ° C, washing at 60 ° C and cold washing.
  • the basic desizing-bleaching bath used in the examples below is as follows:
  • Examples 1 to 4 are comparative examples.
  • Example 5 illustrates a method according to the present invention.
  • Example 3 Only the use of sodium metaborate (Ex. 3) gives a higher degree of white than that obtained with sodium tetraborate decahydrate (Ex. 5 according to the invention), but the level of residual starch obtained in Example 3 is too high (the residual starch level of Example 3 is 0.61 while it is only 0.22 in Example 5 according to the invention).
  • Example 5 the hydrophilicity of Example 5 is 10 times lower than that of Example 3. It will also be noted that the degree of polymerization (DP - 1,620) obtained in Example 5 according to the invention shows that the fiber is not degraded during the desizing - bleaching operation.
  • Examples 6 to 9 are comparative examples.
  • Example 10 illustrates a method according to the present invention.
  • Example 15 illustrates a desizing-bleaching process according to the present invention.
