Abstract

An acid dye composition for dyeing nylon textiles is disclosed, which comprises: an acid dye; and a water soluble Ca2+ compound, wherein, on the basis of a total weight of the acid dye as 100 parts by weight, a content of the water soluble Ca2+ compound is ranged from 0.1 parts by weight to 50 parts by weight. In addition, a use of the aforesaid acid dye composition and a method using the same for dyeing nylon textiles are also disclosed.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An acid dye composition for dyeing nylon textiles, comprising:
 an acid dye; and a water soluble Ca 2+  compound,   wherein, on the basis of a total weight of the acid dye as 100 parts by weight, a content of the water soluble Ca 2+  compound is ranged from 0.1 parts by weight to 50 parts by weight.   
     
     
         2 . The acid dye composition of  claim 1 , wherein a solubility of the water soluble Ca 2+  compound is greater than 20 g per 100 g of water at 20° C. 
     
     
         3 . The acid dye composition of  claim 1 , wherein the water soluble Ca 2+  compound is CaCl 2 , Ca(C 2 H 3 O 2 ) 2 , CaSO 4  or a combination thereof. 
     
     
         4 . The acid dye composition of  claim 3 , wherein the water soluble Ca 2+  compound is CaCl 2 . 
     
     
         5 . The acid dye composition of  claim 1 , wherein the content of the water soluble Ca 2+  compound is ranged from 5 parts by weight to 30 parts by weight. 
     
     
         6 . The acid dye composition of  claim 1 , wherein the acid dye is Acid Black 172, Acid Black ACE, Acid Yellow 220, Acid Red 315, Acid Blue 317, Acid Blue 113 or a combination thereof. 
     
     
         7 . A use of an acid dye composition for dyeing nylon textiles, wherein the acid dye composition comprises:
 an acid dye; and   a water soluble Ca 2+  compound,   wherein, on the basis of a total weight of the acid dye as 100 parts by weight, a content of the water soluble Ca 2+  compound is ranged from 0.1 parts by weight to 50 parts by weight.   
     
     
         8 . The use of  claim 7 , wherein a solubility of the water soluble Ca 2+  compound is greater than 20 g per 100 g of water at 20° C. 
     
     
         9 . The use of  claim 7 , wherein the water soluble Ca 2+  compound is CaCl 2 , Ca(C 2 H 3 O 2 ) 2 , CaSO 4  or a combination thereof. 
     
     
         10 . The use of  claim 7 , wherein the content of the water soluble Ca 2+  compound is ranged from 5 parts by weight to 30 parts by weight. 
     
     
         11 . The use of  claim 7 , wherein the acid dye is Acid Black 172, Acid Black ACE, Acid Yellow 220, Acid Red 315, Acid Blue 317, Acid Blue 113 or a combination thereof. 
     
     
         12 . The use of  claim 7 , wherein on the basis of a use mount of the nylon textiles as 100 parts by weight, a use amount of the acid dye is ranged from 0.1 parts by weight to 10 parts by weight. 
     
     
         13 . The use of  claim 7 , wherein the nylon textiles are a nylon microfiber substrate. 
     
     
         14 . A method for dyeing nylon textiles, comprising the following steps:
 dyeing nylon textiles with an acid dye composition, wherein the acid dye composition comprises:   an acid dye; and a water soluble Ca 2+  compound,   wherein, on the basis of a total weight of the acid dye as 100 parts by weight, a content of the water soluble Ca 2+  compound is ranged from 0.1 parts by weight to 50 parts by weight.   
     
     
         15 . The method of  claim 14 , wherein a solubility of the water soluble Ca 2+  compound is greater than 20 g per 100 g of water at 20° C. 
     
     
         16 . The method of  claim 14 , wherein the water soluble Ca 2+  compound is CaCl 2 , Ca(C 2 H 3 O 2 ) 2 , CaSO 4  or a combination thereof. 
     
     
         17 . The method of  claim 14 , wherein the content of the water soluble Ca 2+  compound is ranged from 5 parts by weight to 30 parts by weight. 
     
     
         18 . The method of  claim 14 , wherein the acid dye is Acid Black 172, Acid Black ACE, Acid Yellow 220, Acid Red 315, Acid Blue 317, Acid Blue 113 or a combination thereof. 
     
     
         19 . The method of  claim 14 , wherein on the basis of a use mount of the nylon textiles as 100 parts by weight, a use amount of the acid dye is ranged from 0.1 parts by weight to 10 parts by weight. 
     
     
         20 . The method of  claim 14 , wherein the nylon textiles are a nylon microfiber substrate.
