  • the exterior appearance of a fabric, and thus of a clothing article made by the fabric, can be modified by using different finishing techniques.
  • the present invention refers to a process for producing a fabric, comprising the following steps:
  • the finishing processes may be applied to the fabric or to the garment including the fabric.
  • the fabric i.e. it is tailored, into a garment
  • the finishing processes may be applied to the fabric or to the garment including the fabric.
  • the process of claim 1 may be carried out on a garment; claim 1 thus encompasses the treatment of a fabric in a garment.
  • a "treated fabric”, i.e. a woven fabric after finishing processes, with an improved (i.e. a "unique") aesthetical effect can be obtained.
  • the obtained fabric, i.e. the "treated” fabric presents a "multi-shaded” effect, namely a "multi-shaded” appearance, previously not available through known finishing processes.
  • a "treated fabric”, i.e. a woven fabric after finishing processes, with a "unique” aesthetical effect can be obtained; in other words, two woven fabrics that are “treated” with the process of the invention, show two different aesthetical results, i.e. the same distribution of color shades is not reproduced from a fabric to another.
  • each "treated fabric”, obtained by the process of the invention shows an aesthetical appearance that is substantially “unique”, i.e. an aesthetical appearance that is substantially “not reproducible”.
  • the treated fabric of the invention shows a plurality of color shades, according to the amount of dye which has been absorbed by the biopolymer layer and reached the underlying woven fabric.
  • a composite fabric comprises a biopolymer layer having non-uniform (i.e. "variable") thickness, different amounts of dye reach the underlying surface (for example, the front side) of the woven fabric, according to the thickness of the biopolymer layer so that the fabric yarns take on different amounts of dye in different regions.
  • the thickness ("T") of the biopolymer layer of a composite fabric according to the invention and the amount of the dye which reaches the woven fabric provided with the biopolymer layer are inversely proportional. In other words, the higher is the thickness of the biopolymer layer, the lower is the amount of dye that reaches the woven fabric provided with the biopolymer layer.
  • T thickness of the biopolymer layer of a composite fabric according to the invention
  • a high amount of dye is absorbed by the biopolymer layer and only a low amount of dye (or none) reaches the woven fabric provided with the biopolymer layer. Therefore, after the removal of the biopolymer layer, a treated fabric that is slightly colored (i.e.
  • the thickness "T" of the biopolymer layer is low, a low amount of dye is absorbed by the biopolymer layer, and thus a high amount of dye reaches the surface (i.e., for example, the front side) of the woven fabric provided with the biopolymer layer. Therefore, after the removal of the biopolymer layer, a treated fabric that is intensely colored (i.e. that is colored in a dark shade of color) is obtained.
  • the term “thickness” refers to the distance between the top and bottom or front and back surfaces of something; e.g., the distance between the top and bottom surfaces of the biopolymer layer.
  • the bottom surface of the biopolymer layer is the surface of the biopolymer layer which contacts the fabric or yarns.
  • the top surface of the biopolymer layer is the surface of the biopolymer layer, opposite to the bottom surface, which does not contact the fabric or yarns.
  • uniform thickness refers to a thickness that is substantially constant (substantially non-variable); e.g. the distance between the top and bottom surfaces of the biopolymer layer does not substantially change along the extension of the biopolymer layer.
  • non-uniform thickness refers to a thickness that is variable; e.g. the distance between the top and bottom surfaces of the biopolymer layer varies (i.e. “changes", i.e. it is not constant) along the extension of the biopolymer layer.
  • a discontinuous biopolymer layer according to the invention can present a predetermined "patterned" distribution of "interruptions" in order to provide a treated fabric with a predetermined pattern of regions of the woven fabric that are "completely” and “directly” dyed, as above mentioned. Therefore, once the biopolymer layer is removed according to step e. of the process of the invention, a treated fabric having a multi-shaded effect further comprising a patterned distribution of "completely dyed” regions can be obtained.
  • the biopolymer layer can act as a "stencil" when the composite fabric is dyed.

  • a microorganism can be genetically modified in order to produce a bacterial biopolymer which is not produced by the same microorganism when it is not genetically modified (i.e., when it is a wild type microorganism).
  • microorganism refers to small unicellular or multicellular living organisms that are too small to be seen with naked eye but are visible under a microscope, and encompasses bacteria, yeast, fungi, viruses and algae. As above mentioned, the term “microorganism” encompasses not genetically modified (i.e. wild type) microorganisms and genetically modified microorganism as well.
  • bacterial biopolymer for sake of simplicity, without however limiting the scope of the invention to polymers produced by “bacteria” only, but encompassing all the polymers that can be produced by a microorganism as above defined.
