Dyed fabric, fiber product in which same is used, and method for dyeing fabric

Abstract

An object of the present invention is to provide a dyed fabric and a textile product made thereof, as well as a dyeing method, which achieve color uniformity of a meta-type wholly aromatic polyamide fiber, a para-type wholly aromatic polyamide fiber and a polyester fiber, even in the case of a fabric containing a meta-type- and para-type-wholly aromatic polyamide fibers and a polyester fiber which are difficult to dye. The present invention relates to a dyed fabric dyed after being shaped into a fabric, characterized in that the fabric includes a meta-type wholly aromatic polyamide fiber, a para-type wholly aromatic polyamide fiber and a polyester fiber and the fabric is a fabric dyed with a cationic dyestuff and a disperse dyestuff, and in that the afterflame time and afterglow time defined in JISL1091A-1 are 1 second or less.

1 . A dyed fabric dyed after being shaped into a fabric,
 characterized in that the fabric comprises a meta-type wholly aromatic polyamide fiber, a para-type wholly aromatic polyamide fiber and a polyester fiber, and the fabric is dyed with a cationic dyestuff and a disperse dyestuff,   and in that the afterflame time and afterglow time defined in JISL1091A-1 are 1 second or less.   
     
     
         2 . The dyed fabric according to  claim 1 , wherein both of the dry rubbing fastness and the wet rubbing fastness defined in JIS L 0849 II method are grade 3 or more. 
     
     
         3 . The dyed fabric according to  claim 1 , wherein the polyester fiber is dyed with the disperse dyestuff by ring-dyeing. 
     
     
         4 . The dyed fabric according to  claim 1 , wherein the residual disperse dyestuff is from 0.01% o.w.f. to 0.5% o.w.f. 
     
     
         5 . The dyed fabric according to  claim 1 , wherein the residual cationic dyestuff is from 0.01% o.w.f. to 16.0% o.w.f 
     
     
         6 . The dyed fabric according to  claim 1 , wherein the weights of the meta-type wholly aromatic polyamide fiber, the para-type wholly aromatic polyamide fiber and the polyester fiber are in the ratio of 60 to 80:1 to 10:5 to 20. 
     
     
         7 . The dyed fabric according to  claim 1 , wherein
 the fabric comprises an electrically-conductive fiber, and   the weights of the meta-type wholly aromatic polyamide fiber, the para-type wholly aromatic polyamide fiber, the polyester fiber and the electrically-conductive fiber are in the ratio of 60 to 80:1 to 10:5 to 20:1 to 4.   
     
     
         8 . The dyed fabric according to  claim 1 , which is made of a blended spun yarn comprising the meta-type wholly aromatic polyamide fiber, the para-type wholly aromatic polyamide fiber and the polyester fiber. 
     
     
         9 . The dyed fabric according to  claim 7 , which is made of a blended spun yarn comprising the meta-type wholly aromatic polyamide fiber, the para-type wholly aromatic polyamide fiber, the polyester fiber and the electrically-conductive fiber. 
     
     
         10 . The dyed fabric according to  claim 1 , wherein
 the water absorption performance defined in AATCC79 prior to washing is 2 seconds or less, and   the water absorption performance defined in AATCC79 after 10 washing cycles defined in ISO6330:2012 (6N-F) is 10 seconds or less.   
     
     
         11 . The dyed fabric according to  claim 1 , which is dyed with 2% o.w.f. or less of the disperse dyestuff after dyed with 20% o.w.f. or less of the cationic dyestuff. 
     
     
         12 . A textile product made of the dyed fabric according to  claim 1 , which is selected from the group consisting of protective suits, fire resistant suits for fire-fighting, firefighter suits, rescue suits, workwear, a police uniform, a camouflage uniform, and a military uniform. 
     
     
         13 . A method for dyeing a fabric, characterized in that
 dyeing a fabric comprising a meta-type wholly aromatic polyamide fiber, a para-type wholly aromatic polyamide fiber and a polyester fiber with a dye solution for wholly aromatic polyamide fiber comprising 20% o.w.f. or less of a cationic dyestuff, and then   dyeing the fabric with a dye solution for polyester fiber comprising 2% o.w.f. or less of a disperse dyestuff.   
     
     
         14 . The dyeing method according to  claim 13 , wherein the dyeing is performed by thermosol dyeing.
