Definitions

  • the invention relates to a process for bleaching of dyed textiles.
  • Some textiles are bleached after dyeing.
  • blue jeans made from indigo-dyed denim can be treated with pumice and/or cellulase, followed by bleaching to obtain a desired, worn appearance.
  • This art also comprises a bleaching with H 2 0 2 ; however, in cases where a strong bleaching is desired, high concentrations of H 2 0 2 have to be used, i.e. concentrations in the order of 5-30%, which makes this bleaching method very expensive; and also, the areas around the zippers are bleached too heavily. Furthermore, the pH value has to be very high in order to achieve the desired effect, this being a disadvantage from both an environmental and an economic point of view.
  • the known art is associated with heavy drawbacks, and the purpose of the invention is the provision of an economical process for bleaching of dyed textiles, which is acceptable from an environmental point of view.
  • the present invention provides a process for bleaching of dyed textiles comprising treatment with a bleach liquor containing (1) H 2 0 2 or a precursor for H 2 0 2 and an enzyme exhibiting peroxidase activity or (2) 0 2 or a precursor for 0 2 and an enzyme exhibiting a suitable oxidase activity.
  • peroxidases act on various amino and phenolic compounds resulting in the production of a colour.
  • peroxidases and certain oxidases may also exert an effect on coloured substances on textiles.
  • the process of the invention is applicable to all types of textile materials, particulaly cellulosic fibers such as cotton, e.g. denim.
  • the textiles may be dyed with any textile color.
  • a comprehensive cata ⁇ logue of commonly used textile dyes both synthetic (such as azo dyes) and natural or nature-identical (by which is meant a substance which is produced synthetically, but which in structure and properties is identical to the natural compound), e.g. indigo.
  • a comprehensive catalogue of such dyes is found in the Color Index.3rd ed. Vol. 1-8.
  • the process of the invention is able to bleach even practically insoluble dyestuffs like indigo. Enzyme
  • Suitable oxidases and peroxidases are those which use molecular oxygen or hydrogen peroxide to oxidize aromatic compounds, in particular phenolic, e.g. polyphenolic,
  • phenolic e.g. polyphenolic
  • bleaching enzymes are collectively termed bleaching enzymes in the following.
  • bleaching enzymes examples include catechol oxidase (EC 1.10.3.1), laccase (EC 1.10.3.2), peroxidase (EC 1.11.1.7), chloride peroxidase (EC 1.11.1.10) and phenol oxidase (EC 1.14.18.1).
  • Bleaching enzymes which may be employed for the present purpose may be derived from plants (e.g. horseradish peroxidase) or microorganisms such as fungi or bacteria.
  • suitable peroxidases are those derived from a strain of Coprinus, e.g. C. cinerius or C. macrorhizus, or from a strain of Bacillus, e.g. ⁇ . pumil ⁇ s, particularly peroxidase according to PCT/DK 90/00260.
  • Such enzymes may be produced, by methods known in the art, by cultivating the strain on a suitable nutrient medium or by transferring the genetic information to a suitable host organism and cultivating this.
  • a suitable amount of the enzyme is generally 0.01 - 100 mg of enzyme protein per litre of bleach liquor, particularly 0.1 - 10 mg/l.
  • Particularly preferred bleaching enzymes are those which are active at pH values of 4 - 10, especially 5-9.
  • Suitable precursors for H 2 0 2 are for instance a perborate or a percarbonate or an enzymatic system capable of generating H 2 0 2 .
  • the concentration of H 2 0 2 or H 2 0 2 precursor is preferably 0.1 mM - 100 mM H 2 0 2 , particularly 0.5 mM - 10 mM H 2 0 2 .
  • a concentration above 100 mM H 2 0 2 does not improve the bleaching effect significantly, and a concentration below 0.1 mM H 2 0 2 tends to be too low in relation to the bleaching effect.
  • the bleaching liquor preferably has a pH of 4 - 10, particularly 5 - 9. It has surprisingly been found that the addition of another oxidizable substrate (for the bleaching enzyme used in the process of the invention) at the 5 beginning or during the washing and/or rinsing process may enhance the backstaining inhibitory effect of the bleaching enzyme employed. This is thought to be ascribable to the formation of short-lived radicals or other oxidised states of this substrate which participate in the bleaching or other modification of the coloured substance.
  • oxidizable substrates are metal ions, e.g. Mn ++ , halide ions, e.g. chloride or bromide ions, or organic compounds such as phenols, e.g.

  • the amount of oxidizable substrate to be added is suitably between about 1 ⁇ M and 10 mM.
  • the process according to the invention primarily is a bleaching process, but it has been found that back staining, i.e. coloring of the textile either with small dyestuff particles or with small, dyed textile fibres, is heavily reduced or completely avoided under the conditions prevailing during the process according to the invention.
  • the bleaching process can be carried out as a separate step, or simultaneously with other steps, e.g. a washing or rinsing step.
  • the bleaching process according to the invention can be carried out simultaneously with a treatment with cellulase (and optionally pumice) to create a desired worn look by forming local variations in colour density, as described in American dye stuff reporter, Sept. 90, D. Kochavi, T. Videbaek and D. Cedroni, Optimizing processing conditions in enzymatic stone washing.
  • a preferred embodiment of the process according to the invention is characterized by the fact that the enzyme is a catechol oxidase (EC 1.10.3.1), a laccase (EC 1.10.3.2), a peroxidase (EC 1.11.1.7) or a chloride peroxidase (EC).

If the concentration of H 2 0 2 is less than 0.1 mM, the effect is negligible, and if the concentration of H 2 0 2 or a precursor for H 2 0 2 is above 100 mM, the H 2 0 2 tends to inactivate the enzyme.

In this manner the desired worn look is generated satisfactorily. It has previously been reported that peroxidases may decolourize certain pigments (cf. for instance W. Schreiber, Biochem. Biophvs. Res. Commun. 63 (2), 1975, pp. 509-514, describing the degradation of 3-hydroxyflavone by horseradish peroxidase; A. Ben Aziz, Phvtochemistrv 10, 1971, pp. 1445-1452, describing the bleaching of carotene by means of a peroxidase; and B.P.
  • Ben Aziz et al. and Wasserman et al. present the bleaching action of peroxidases on carotene and betaiain, respectively, as a problem when using these pigments as food colourants, which problem must be counteracted by including an antioxidant in the foodstuff in question. Thus, they do not consider the peroxidase- mediated bleaching of these pigments to have any practical utility in itself.

Abstract

Le procédé de blanchiment de textiles colorés comprend le traitement avec un liquide de blanchiment contenant (1) H2O2 ou un précurseur de H2O2 et une enzyme caractérisée par une activité de peroxydase ou (2) O2 ou un précurseur de O2 et une enzyme caractérisée par une activité d'oxydase appropriée. Ledit procédé s'avère intéressant du point de vue de l'environnement: seule une quantité relativement faible de H2O2 est requise, et des valeurs de pH très élevées ne sont pas nécessaires afin d'obtenir un effet de blanchiment satisfaisant.
