Abstract |
The analysis method of relative adsorption of disperse dyes on impregnated
polyurethane resin and polyester fiber separately was investigated. The solvents for
extracting the dyes from polyurethane resin and polyester fiber were determined by
acetone and DMF, respectively. By extracting the dyed fibers with acetone at room
temperature within 30 minutes, the dyes adsorbed only on the polyurethane resin could
be extracted. And then by additional extracting the same fabrics with DMF at 95¡É
for longer than 1 hour, the dyes adsorbed on polyester fabrics was extracted. This
means that the dyes adsorbed on polyurethane and polyester could be extracted
separately and that relative adsorption of the dyes on the both components could be
analyzed quantitatively. Using this analysis method, the relative adsorption of a
disperse dye was investigated after reduction clearing with various conditions. |
