Method of dyeing fiber with mugwort and product dyed thereby

Abstract

The present invention discloses a method of dyeing a fiber with mugwort for effectively maintaining health and preventing diseases by applying mugwort constituents to fibers. The method comprises the steps of making a mugwort salt bath by adding mugwort powder or extraction liquor to water; heating the salt bath; putting the fiber to be dyed in the salt bath and stirring it for 10 to 30 minutes at a temperature of 50 to 100 C; rinsing and drying the fiber; and then dipping the fiber in an aqueous solution of organic binder with a temperature of 50 to 80 C for 5 to 10 minutes, drying the fiber afterwards. In another embodiment, to apply mugwort to synthetic fibers, a predetermined amount of mugwort extraction liquor may be added to a resin to be used in the process of producing fibrous yarns.

What is claimed is:  
     
         1 . A method of dyeing a fiber with mugwort, comprising: 
 a first step of making a mugowt salt bath by adding mugwort powder or mugwort extraction liquor to water;    a second step of heating the mugwort salt bath made in the first step, putting a fiber to be dyed therein and stirring the same for 10 to 30 minutes while keeping the temperature of the mugwort salt bath at 50 to 100° C.; and    a third step of rinsing the fiber treated in the second step and drying the same.    
     
     
         2 . The method of  claim 1 , wherein the mugwort powder is made by drying picked mugwort and crushing the same at a grain size of less than 500 μm.  
     
     
         3 . The method of  claim 1 , wherein the mugwort extraction liquor is extracted by rinsing picked mugwort, drying the same and then heating the same.  
     
     
         4 . The method of  claim 1 , further comprising a fourth step of dipping the fiber of the third step in an aqueous solution of organic binder with 50 to 80° C. for 5 to 10 minutes, taking the same and then drying the same.  
     
     
         5 . A fibrous product dyed by a method of dyeing a fiber with mugwort, comprising: 
 a first step of making a mugowt salt bath by adding mugwort powder or mugwort extraction liquor to water;    a second step of heating the mugwort salt bath made in the first step, putting a fiber to be dyed therein and stirring the same for 10 to 30 minutes while keeping the temperature of the mugwort salt bath at 50 to 100° C.; and a third step of rinsing the fiber treated in the second step and drying the same.
