Method for manufacturing dyed woven or knitted fabric using metallic yarn and polyester yarn and fabric manufactured using the method

Abstract

A method for manufacturing dyed woven or knitted fabric includes preparing woven or knitted fabric using metallic yarn and normal-pressure dyeing polyester yarn having an elasticity modulus of 400 to 600 kg/mm 2 and an elongation of 30 to 40%, fabricating a dye bath by putting a dye solution obtained by dispersing a dye in water, dyeing the woven or knitted fabric by putting the prepared woven or knitted fabric into the fabricated dye bath, raising a temperature of the dye bath starting from 35 to 45° C. for 30 to 50 minutes at a rate of 1.2 to 1.5° C./min, and maintaining the heated dye bath at 90 to 100° C. for 15 to 25 minutes, and washing the dyed woven or knitted fabric. The dyed woven or knitted fabric has a light reflection reduction rate of 20% to 30%.

1 . A method for manufacturing dyed woven or knitted fabric, comprising:
 preparing woven or knitted fabric using metallic yarn and normal-pressure dyeing polyester yarn having an elasticity modulus of 400 to 600 kg/mm 2  and an elongation of 30 to 40%;   fabricating a dye bath by putting a dye solution obtained by dispersing a dye in water;   dyeing the woven or knitted fabric by putting the prepared woven or knitted fabric into the fabricated dye bath, raising a temperature of the dye bath starting from 35 to 45° C. for 30 to 50 minutes at rate of 1.2 to 1.5° C./min, and maintaining the heated dye bath at 90 to 100° C. for 15 to 25 minutes; and   washing the dyed woven or knitted fabric.   
     
     
         2 . The method for manufacturing dyed woven or knitted fabric according to  claim 1 , before dyeing the woven or knitted fabric, further comprising:
 Processing the prepared woven or knitted fabric at 75 to 85° C. for 15 to 25 minutes by using a de-oiling agent before the prepared woven or knitted fabric is put into the dye bath.   
     
     
         3 . The method for manufacturing dyed woven or knitted fabric according to  claim 1 , wherein the dye solution includes at least one of glacial acetic acid, a dispersing agent, a softening agent, a stain repellant, and their mixtures. 
     
     
         4 . Dyed woven or knitted fabric, which is manufacture by the method defined in  claim 1  and has a light reflection reduction rate of  20 % to 30%. 
     
     
         5 . Dyed woven or knitted fabric, which is manufacture by the method defined in  claim 2  and has a light reflection reduction rate of 20% to 30%. 
     
     
         6 . Dyed woven or knitted fabric, which is manufacture by the method defined in  claim 3  and has a light reflection reduction rate of 20% to 30%.
