Definitions

  • the present invention relates to a method for preventing or minimizing color position on fabric during a decoloring process, especially during a "stone-wash" process.
  • the fabric is preferably indigo-dyed cotton or cotton-containing fabrics.
  • the anti-color redeposition agent used is a polyester, preferably a terephthalic acid polyester-polyether polymer.
  • the pumice stone was discovered to accelerate the aging process of the indigo-dyed parts.
  • the "stone-wash look” is made possible by the fact that the dye is essentially only applied to the outer regions of the fibers. This is characteristic of an indigo dye. This is referred to as a so-called coat color, in which the color does not penetrate into the yarn, but it envelops like a coat and the core of the yarn or the fibers is not discolored.
  • the enzyme used here is usually a cellulase.
  • the cellulase is temporarily bound to the cellulose by an anchor and cleaves it to its 1,4-betaglucosidic linkage.
  • the cellulase is temporarily bound to the cellulose by an anchor and cleaves it to its 1,4-betaglucosidic linkage.
  • the cellulase is temporarily bound to the cellulose by an anchor and cleaves it to its 1,4-betaglucosidic linkage.
  • the cellulase is temporarily bound to the cellulose by an anchor and cleaves it to its 1,4-betaglucosidic linkage.
  • the surface of the cotton fiber on which the indigo dye is located partially detached.
  • underneath, not colored and thus white areas of the cotton fiber come to light.
  • the use of the cellulases achieves an optical effect, which corresponds to the use of pumice.
  • the cellulases used in the enzymatic stone-wash process can be divided into two groups: acidic and neutral cellulases.
  • the terms “acidic” and “neutral” are used to describe the pH at which the enzyme develops its optimum performance. For acid cellulases, this is the range of about 4 to 6, while neutral cellulases show their optimum performance at pH values of about 6 to 8.
  • a major difference is the higher abrasion that allows acidic cellulases compared to neutral ones.
  • acidic cellulases the same abrasion properties can be set when using 10 to 20% of the amount of neutral cellulase.
  • acid cellulases allow shorter treatment times and are also significantly cheaper, which leads to an overall economic advantage. Disadvantages, however, are the so-called "backstaining" (color printing position).
  • Under color printing position refers to a back discoloration or mulch including the cotton with peeled dye or dye on fiber remains. These deposits can be observed at various points, such as inside pockets, labels, seams, zippers, but also in particular on the inner and outer surface of the denim. Backstaining creates an undesirable low-contrast appearance of the product.
  • the color printing position is a function of the cellulase mixture used, the dye, the type of surfactant used, the surfactant concentration and the pH.
  • nonionic fatty alcohol ethoxylates with anionic alkanesulfonate to achieve an anti-redepositon effect is described.
  • anionic surfactants lead to a negative interaction with the cellulase, such that their abrasiveness is reduced.
  • the WO 01/57173 describes an enzymatic 2-component system by means of which it is possible to produce a good stone-wash effect on dyed cotton or cotton-containing fabrics with a simultaneously very low Backstaining.
  • the 2-component system contains, in addition to a cellulase component, special aqueous polymer dispersions whose solid particles are styrene / (meth) acrylic acid ester copolymers which have been grafted onto starch as the graft base.
  • the WO 95/35363 describes a method for producing a stone-wash effect by using acidic cellulases in the presence of color anti redeposition agents selected from the group of natural and synthetic, inorganic silicates, polyalkylene oxides, acrylic acid polymers and natural and synthetic or semisynthetic polysaccharides.
  • color transfer inhibitors described in the prior art such as polyvinylpyrollidones, polyvinylpyridine N-oxides, etc.
  • these compounds are not effective enough when it comes to backstaining
  • indigo which may be - without wishing to be bound by theory - may be due to the extreme hydrophobicity of this dye.
  • Polyesters are already preparable by reacting polymeric waste terephthalates, such as polyethylene terephthalate, polybutylene terephthalate or poly (cyclohexanedimethanol) terephthalate, glycols and oxyalkylated polyols having at least 3 hydroxyl groups, which are used in dyeing and Entfärbereaen to prevent the color printing position.

Instead of pumice sintered perlites are often used, which lead due to their hardness to less abrasion during the process. In addition, they are smaller than pumice stones, have a larger surface area, which makes it possible to rinse the stones with the wash liquor.

Finally, the tissue i.d.R. under standard conditions bleached with the bleaching agents described in the prior art, e.g. Hypochlorite.
  • the antiredeposition agents described in the method according to the invention are also distinguished, inter alia, by their affinities for hydrophobic surfaces such as, for example, polyester, polyamide or their blended fabrics with cotton. Since the accessories of jeans such as pocket lining, zippers, labels, seams, etc. are often made of these materials, it is recommended additives of the invention not only in the actual stone-wash process but before, ie in the desizing of the fiber. Here, these accessories receive an efficient surface impregnation, which essentially means that the indigo released in the stone-wash process is less attracted to these surfaces.
