I don't think the difference is related to Q, you can wind two coils, 
one with bare wire and the other with cotton coated wire and if the
spacing between turns of the actual wire is the same the resultant Q 
is going to be the same, but the cotton coated wire is going to have 
better turn to turn insulation because the cotton is wicking up more 
insulation between the turns and hence those coils are capable of 
handeling greater turn to turn voltages. This seems in line with the 
fact that the coil wound with enamel coated wire perform much better 
than those wound with bare wire.
