Definitions

  • the invention relates to methods for producing a stonewashed effect in fabrics and garments while reducing redeposition of dye on the treated materials.
  • stonewashing is considered a process whereby color is removed from a cellulosic garment or fabric by the mechanical abrasion of pumice stones or other abrasive materials, usually in a water bath in a tumbler or washer, such that localized abrasion creates lighter spots or areas on the surface of said fabric or garment leaving a relatively untouched background.
  • processes which produce a similar appearance to said abraded fabric or garments by chemical or enzymatic means, or combinations of the above with or without mechanical abrasion are included in the definition of stonewashing as it is accepted in the industry.
  • cellulase enzymes are typically divided into two groups: those with greatest activity at a neutral pH range (pH about 6 to 8), and those with greatest activity in the acid pH range (pH about 4 to 6). These ranges represent the pH values of optimum performance, even though each type of enzyme has some activity outside its stated pH range. Both types are commonly used to impart the "stonewashed" appearance and both have advantages and disadvantages.
  • neutral cellulase treatments are that only a moderate amount of indigo dye removed during the washing process is redeposited onto the white portions of the fabric, thus producing stonewashed denim garments that have bright, clean appearing highlighted areas.
  • the major disadvantage is that, typically, a neutral cellulase enzyme will react somewhat slower than an acid cellulase enzyme, thus lengthening processing times.
  • a major advantage of the acid cellulase treatments is that the reaction on fabric is much faster than a neutral cellulase enzyme. A reaction time of two to five times faster than a similar treatment with a neutral cellulase enzyme is not uncommon.
  • the major disadvantage is that a greater amount of dye is redeposited onto the garments due in part to the lower solubility of indigo at the lower pH.
  • compositions for chemically stonewashing fabrics or garments generally are set forth in, for example, U.S. Patent Nos. 4,832,864, 4,912,056, 5,006,126 and 5,122,159. Improved compositions and techniques are required, however, for processing dyed material with fast-acting acid cellulase enzyme treatments while reducing the quantity of redeposited dye, thus rapidly yielding garments with areas of bright, clean contrast and an attractive stonewashed appearance.
  • Still another object of the present invention is to provide a method as aforesaid which is particularly well-adapted for processing indigo dyed denim fabrics or garments.
  • the present invention resides in an improved method for treating dyed fabric, either in unsewn form or in the form of a garment, to produce a stonewashed effect by treating said fabric with a water-based composition having an acidic pH and including at least one acid cellulase enzyme and a dye redeposition inhibiting additive selected from the group consisting of natural and synthetic inorganic silicates, polyalkylene oxide polymers, acrylic polymers (homopolymers and copolymers) and natural, synthetic and semisynthetic polysaccharides, including natural and synthetic gums.
  • novel method utilizing the foregoing additives enables the use of fast- acting acid cellulase enzymes to remove dye and cause the desired localized variations in color density while substantially preventing "backstaining", the redeposition of dye (particularly indigo dye) from the low pH wash water onto the treated fabric.
  • the improved wet-processing method of the invention involves contacting dyed cellulosic fabrics, principally cotton denim fabrics, with an aqueous or water-based solution containing (a) a cellulase enzyme having greatest activity in the acid pH range, and (b) a dye redeposition inhibiting additive, as well as optionally other conventional additives such as buffers, surfactants, enzyme activators, solubilizing agents and the like.
  • a cellulase enzyme having greatest activity in the acid pH range
  • a dye redeposition inhibiting additive as well as optionally other conventional additives such as buffers, surfactants, enzyme activators, solubilizing agents and the like.
  • the fabric treated in accordance with the invention may be in unsewn form or sewn in the form of a garment or other article composed of sewn fabric, preferably a new (unworn) garment or article
  • stonewashed appearance refers to an appearance including local areas of variation in color density on the surface of dyed cellulosic fabrics, resembling the appearance created by mechanical abrasion of the fabric with pumice or other "stones".
  • Stonewashing is normally carried out in commercial washing machines, cylindrical tumblers, converted dryers or similar pieces of equipment.
  • the necessary parameters for practice of the subject method are that there must be a means to contain the wash liquor during the process, along with the garments, fabric, or items being stonewashed, such that they and the enzymes and other processing chemicals can make constant or intermittent contact.
  • there must be a means of introducing mechanical energy into the system allowing the surfaces of the items to be stonewashed to rub against other surfaces, including other fabrics or items being stonewashed. This, in the case of a washing machine or tumbler, is accomplished by rotating the cylinder containing the garments, etc. at such a speed as to allow the garments to move about inside and rub against each other.
  • the stonewash process typically consists of several *steps, rather than a single exposure to cellulase enzyme and/or pumice stones.
  • the garments are first typically desized using (a) amylase enzymes and surfactants, (b) oxidizers, alkalis, and surfactants, (c) solvents and surfactants or (d) hot water. This is frequently, but not necessarily, followed by one or more rinses.
  • the abrasion step normally follows, where the cellulase enzyme and other auxiliary chemicals are used to create the abraded appearance. This is the step during which the dye redeposition preventing additives would normally be present according to the invention.
  • a bleach step (only if the overall color is to be lightened), an antichlor step (only if a bleach step is used), a clean-up step where detergents and brighteners are frequently added to wash away excess loose dye, one or more rinses, and a final softener application. Subsequently, the garments are extracted to remove excess water, then dried and pressed.
  • the additives may provide some benefit if added to the desize operation, the rinses before or after the abrasion, in the cleanup step, or in multiple steps.
  • indigo dye is by far the most common dye used on stonewashed fabrics and garments
  • the stonewash concept applies to any fabric, garment, or article which is made from cellulosic fibers, yarns, or threads, in whole or in part, and is dyed, pigmented, or otherwise colored in such a way as to have a differential of color between the surface and the center of said fibers, threads or yarns, whether the colorant is a vat dye (such as indigo), a pigment (or pigment dye), a sulfur dye, or another classification of dyestuff.
  • vat dye such as indigo
  • a pigment or pigment dye
  • sulfur dye or another classification of dyestuff
  • the key concept is that the fibers or yarns are "ring dyed", named for the resulting appearance of a cross-section of the dyed fiber, being more heavily dyed on the outermost ring of the fiber, less heavily dyed (or not dyed at all) at the center core.
  • the stonewashing process damages the outermost portion of the cellulosic fibers, exposing the undyed (or lighter-dyed) centers of the fibers.
  • the dye redeposition or backstaining preventing additives to be used in the novel methods are selected from the group consisting of natural and synthetic inorganic silicates, such as zeolites, kaolin and bentonite clays; polyalkylene oxide polymers, including polyalkylene oxide polyamine copolymers; acrylic homopolymers and copolymers; and natural, synthetic and semisynthetic polysaccharides, such as natural and synthetic gums and cellulosic polymers.

  • Suitable cellulase enzymes for use in the novel stonewashing method include any cellulases, including those produced from fungal or bacterial sources that are optimally active in acidic solutions in degrading cellulosic fibers.
  • the invention is not limited to any particular cellulase enzymes or any particular sources for such enzymes, but instead comprehends the use of any enzymes with cellulose degrading activity maximized in an acidic medium, which may be defined as a medium with a pH less than 7.0, but preferably within a pH range of about 4 to about 6.
  • the dye redeposition or backstaining inhibiting additives be present in the fabric treatment solution in a weight (w/w) concentration not less than about 0.005%.
  • This minimum level may vary depending on the class of additives utilized. For example, the following are representative concentration ranges for the various classes of redeposition preventing additives, based on experimental test results:
  • Natural/synthetic inorganic silicates .025 - 5.0%
  • Polyalkyleneoxide polymers .025 - 2.5%
  • Polysaccharide polymers .005 - 5.0%
  • Acrylic homopolymers and copolymers .005 - 8.0% It should be stressed that the above weight concentration ranges are based on the total weight of wash liquor in which the fabric is immersed and/or tumbled.
