Abstract
A discrete, well defined pattern is produced on colored fabric by applying to the desired area of the fabric a viscous mixture of fine mineral particles, water and one or more bleaching agents. The viscous mixture remains confined to the designated area and permeates the fabric. After a controlled, finite period of time, the mixture is rinsed away, leaving a well defined area from which the fabric coloration has been removed.
Claims15
A method for producing a desired design on the surface of colored fabric comprising the steps of;
- a.) applying to a discrete, selective area of said fabric, a viscous mixture of fine inert, mineral material, water and one or more compounds selected from the group consisting of sodium hypochlorite and sodium bromite, said viscous mixture comprising about 50 to 75 percent by weight fine sand and 50 to 25 percent by weight of an aqueous solution containing about 2 to 20 weight percent of at least one of said sodium hypochlorite and sodium bromite,
- b.) allowing said viscous mixture to permeate and remain in contact with said fabric for a sufficient period of time to destroy at least a portion of the coloration present in said fabric, and
- c.) removing said viscous mixture at the end of said period of time from the fabric to leave a discrete well defined color discharged pattern on the fabric.
A method for producing a color discharged design on the surface of colored denim fabric comprising the steps of:
- a.) securing a stencil forming a design against said colored denim fabric leaving a discrete selective pattern of fabric exposed;
- b.) applying to said discrete selective pattern of said denim fabric defined by said stencil, a viscous mixture of 50 to 75 weight percent sand and 50 to 25 weight percent of a 2-10 percent aqueous solution of one or more compounds selected from the group consisting of sodium hypochlorite and sodium bromite;
- c.) allowing said viscous mixture to permeate and remain in contact with said denim fabric for about 10 to 60 minutes to destroy at least a portion of coloration present in said fabric;
- d.) removing said viscous mixture by washing the viscous mixture from the denim fabric with water;
- and
- e.) removing the stencil from the denim fabric to leave a discrete well defined color discharged pattern on the denim fabric.
A method for producing a bleached design on the surface of colored blue denim fabric comprising the steps of:
- a.) washing a blue denim fabric in water heated at 120.degree.-140.degree. F.;
- b.) drying the blue denim fabric;
- c.) pressing the blue denim fabric;
- d.) securing a stencil to the blue denim fabric forming a design against said colored blue denim fabric leaving a discrete selective pattern of blue denim fabric exposed;
- e.) applying to said discrete selective pattern of said exposed fabric defined by said stencil, a viscous mixture of 50 to 75 weight percent sand and 50 to 25 weight percent of a 2-10 percent aqueous solution of one or more compounds selected from the group consisting of sodium hypochlorite and sodium bromite;
- f.) allowing said viscous mixture to permeate and remain in contact with said fabric for about 10 to 60 minutes to destroy at least a portion of coloration present in said blue denim fabric;
- g.) removing said viscous mixture by washing the viscous mixture from the blue denim fabric with water;
- and
- h.) removing the stencil from the blue denim fabric to leave a discrete well defined color discharged pattern on the blue denim fabric.
