Abstract

A method of dyeing a fabric is provided. The method includes removing folds from the fabric, spraying a dye on a first side of the fabric, and exposing the fabric to a migration and fixation process prior to the dye drying on the first side so that the dye migrates from the first side to a second side of the fabric and reacts with and affixes to a component of the fabric.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A method of dyeing a fabric comprising: 
 removing folds from the fabric;    spraying a dye on a first side of the fabric; and    exposing the fabric to a migration and fixation process prior to said dye drying on said first side so that said dye migrates from said first side to a second side of the fabric and reacts with and affixes to a component of the fabric.    
     
     
         2 . The method as in  claim 1 , wherein the fabric is a natural fabric, a synthetic fabric, and any combination thereof.  
     
     
         3 . The method as in  claim 1 , wherein the fabric is a synthetic fabric having an amine site with which said dye reacts and affixes.  
     
     
         4 . The method as in  claim 3 , wherein the synthetic fabric is a fabric selected from the group consisting of a polyamide fabric, an elastane fabric, and any combination thereof.  
     
     
         5 . The method as in  claim 3 , wherein the synthetic fabric is selected from the group consisting of lycra, nylon, spandex, and any combinations thereof.  
     
     
         6 . The method as in  claim 1 , wherein said reaction and affixation between said dye and said component forms an attachment selected from the group consisting of a covalent bond, an ionic bond, a disbursement into the fiber molecule, and any combinations of the foregoing.  
     
     
         7 . The method as in  claim 1 , wherein said dye is water soluble.  
     
     
         8 . The method as in  claim 1 , wherein said migration and fixation process comprises applying steam and heat to the fabric for a desired time period.  
     
     
         9 . The method as in  claim 8 , wherein said desired time period is about 1 minute to about 7 minutes.  
     
     
         10 . The method as in  claim 9 , wherein said desired time period is about 3 minutes to about 5 minutes.  
     
     
         11 . The method as in  claim 1 , wherein the garment is brassiere, a shirt, a pair of pants, a pair of underwear, a pair of panties, a sock, a skirt, a dress, a pair of shorts, a coat, a suit, a scarf, a glove, and a hat.  
     
     
         12 . A method of dyeing a garment made of fabric comprising: 
 disposing the garment on a carrier so that a first side of the garment faces away from said carrier and a second side faces said carrier;    spraying said first side with a dye; and    steaming and heating the garment prior to said dye drying on said first side so that said dye migrates from said first side to said second side and reacts with and affixes to a component of the fabric.    
     
     
         13 . The method as in  claim 12 , wherein said carrier shapes the garment to a desired state.  
     
     
         14 . The method as in  claim 13 , wherein said desired state comprises removing folds and creases in the garment.  
     
     
         15 . The method as in  claim 13 , wherein the garment is brassiere, a shirt, a pair of pants, a pair of underwear, a pair of panties, a sock, a skirt, a dress, a pair of shorts, a coat, a suit, a scarf, a glove, and a hat.  
     
     
         16 . The method as in  claim 12 , wherein spraying said first side comprises moving a spray nozzle with respect to said first side.  
     
     
         17 . The method as in  claim 12 , wherein the fabric is a synthetic fabric having an amine site with which said dye reacts and affixes.  
     
     
         18 . The method as in  claim 17 , wherein said synthetic fabric is a fabric selected from the group consisting of a polyamide fabric, an elastane fabric, and any combination thereof.  
     
     
         19 . The method as in  claim 17 , wherein the synthetic fabric is selected from the group consisting of lycra, nylon, spandex, and any combinations thereof.  
     
     
         20 . The method as in  claim 12 , wherein the fabric is a natural fabric, a synthetic fabric, and any combination thereof.  
     
     
         21 . The method as in  claim 12 , wherein said dye is water-soluble.
