Abstract

A method of dyeing a textile product to achieve a desired appearance effect including the steps of applying an aqueous pretreatment composition of epoxy ammonium salt, caustic and wetting agent to a textile product in a selected manner to achieve a desired coverage of the pretreatment composition to the textile product, drying the textile product, dyeing the textile product to achieve an appearance effect corresponding to the selected manner of application of the pretreatment composition to the textile product. According to one preferred embodiment of the invention, the step of applying the pretreatment composition to the product is selected from the group of application methods which includes padding, spraying, brushing, dripping, writing and roller printing.

Claims

exact text as granted — not AI-modified
I claim:  
     
         1 . A method of dyeing a textile product to achieve a desired appearance effect, and comprising the steps of: 
 (a) applying an aqueous pretreatment composition of epoxy ammonium salt, caustic and wetting agent to a textile product in a selected manner to achieve a desired coverage of the pretreatment composition to the textile product;    (b) drying the textile product; and    (c) dyeing the textile product to achieve an appearance effect corresponding to the selected manner of application of the pretreatment composition to the textile product.    
     
     
         2 . A method of dyeing a textile product according to  claim 1 , wherein the step of applying the pretreatment composition to the textile product is selected from the group of application methods consisting of padding, spraying, brushing, dripping, writing and roller printing.  
     
     
         3 . A method of dyeing a textile product according to  claim 2 , wherein the textile product is selected from the group consisting of woven fabric, nonwoven fabric and knitted fabric.  
     
     
         4 . A method of dyeing a textile product according to  claim 2 , wherein the textile product is selected from the group consisting of woven or knitted garments, woven or knitted garment components, and knitted hosiery.  
     
     
         5 . A method of dyeing a textile product according to  claim 2  or  3 , wherein the step of applying the pretreatment composition includes the step of moving the fabric past a stationary composition application station.  
     
     
         6 . A method of dyeing a textile product according to  claim 1 ,  2 ,  3 ,  4  or  5 , wherein the step of dyeing the fabric comprises the step of dyeing the fabric with a reactive dye.  
     
     
         7 . A method of dyeing a textile product according to  claim 1 , wherein the step of applying the pretreatment composition comprises the step of differentially treating the fabric so that only some areas of the fabric receive the pretreatment composition.  
     
     
         8 . A method of dyeing a textile product according to  claim 1 , wherein the step of applying the pretreatment composition comprises the step of differentially treating the fabric whereby some areas of the fabric receive a heavier application of pretreatment composition than other areas.  
     
     
         9 . A method of dyeing a textile product according to  claim 1 , wherein the step of applying the pretreatment composition comprises pad batching the textile product, and further includes the steps of scouring and bleaching the pretreated textile product before drying.  
     
     
         10 . A method of dyeing a textile product to achieve a desired appearance effect, and comprising the steps of: 
 (a) applying an aqueous composition of caustic and wetting agent to a textile product;    (b) applying an aqueous composition of epoxy ammonium salt to the textile product treated in accordance with (a) in a selected manner to achieve a desired coverage;    (c) drying the textile product; and    (d) dyeing the textile product to achieve an appearance effect corresponding to the selected manner of application of the pretreatment composition to the textile product.    
     
     
         11 . A dyed textile fabric having a predetermined appearance effect resulting from being treated according to the method steps of: 
 (a) applying an aqueous pretreatment composition of epoxy ammonium salt, caustic and wetting agent to the textile product in a selected manner to achieve a desired coverage of the pretreatment composition to the textile product;    (b) drying the textile product; and    (c) dyeing the textile product to achieve an appearance effect corresponding to the selected manner of application of the pretreatment composition to the textile product.    
     
     
         12 . A dyed textile product according to  claim 11 , wherein the step of applying the pretreatment composition to the textile product is selected from the group of application methods consisting of padding, spraying, brushing, dripping, writing and roller printing.  
     
     
         13 . A textile product according to  claim 12 , wherein the textile product is selected from the group consisting of woven fabric, nonwoven fabric and knitted fabric.  
     
     
         14 . A textile product according to  claim 12 , wherein the textile product is selected from the group consisting of woven or knitted garments, woven or knitted garment components, and knitted hosiery.  
     
     
         15 . A textile product according to  claim 12  or  13 , wherein the step of applying the pretreatment composition includes the step of moving the fabric past a stationary composition application station.  
     
     
         16 . A textile product according to  claim 11 ,  12 ,  13 ,  14  or  15 , wherein the step of dyeing the fabric comprises the step of dyeing the fabric with a reactive dye.  
     
     
         17 . A textile product according to  claim 11 , wherein the step of applying the pretreatment composition comprises the step of differentially treating the fabric so that only some areas of the fabric receive the pretreatment composition.  
     
     
         18 . A textile product according to  claim 11 , wherein the step of applying the pretreatment composition comprises the step of differentially treating the fabric whereby some areas of the fabric receive a heavier application of pretreatment composition than other areas.  
     
     
         19 . A textile product according to  claim 11 , wherein the step of applying the pretreatment composition comprises pad batching the textile product, and further includes the steps of scouring and bleaching the pretreated textile product before drying.  
     
     
         20 . A dyed textile fabric having a predetermined appearance effect resulting from being treated according to the method steps of: 
 (a) applying an aqueous composition of caustic and wetting agent to a textile product;    (b) applying an aqueous composition of epoxy ammonium salt to the textile product treated in accordance with (a) in a selected manner to achieve a desired coverage;    (c) drying the textile product; and    (d) dyeing the textile product to achieve an appearance effect corresponding to the selected manner of application of the pretreatment composition to the textile product.
