Method for color monitoring the level of finish applied to textile materials and for color coding textile materials

摘要

A method is provided for temporary coloration of textile materials which comprises applying to said textile materials an amine-reducible tint in an amount sufficient to provide coloration to said textile material, said tint being characterized by the formula:R{A-[alkeneoxy constituent)_nX]_m}_pwherein RA is the organic, easily reducible dyestuff radical, A is a linking moiety in said organic, easily reducible dyestuff radical selected from the group consisting of -N-, -O-, -S-, or -CO₂-, the alkenyl moiety of said alkyleneoxy constituent contains from 2 to about 4 carbon atoms, n is an integer of from 2 to about 300, m is 1 when A is -O-, -S-, -CO₂- and 2 when A is -N-, p is an integer of from 1 to 5, and X is a member of the group consisting of -H-, -alkyl, -alkylcarboxylate, or -arylcarboxylate; and contacting said amine-reducible tint with an amine compound in an amount sufficient to reduce said tint whereby said coloration of said textile material is removed.
