of the embossed pile is worse than that of the unembossed carpet pile the following test methods are employed to determine whether or not the protective agent being evaluated meets the aforementioned requirements a compatibility with the embossing print paste determined visually be inspecting for any separation or precipitation which may occur during a 16 hour ageing period at room conditions there must not be any separation which cannot be easily and uniformly dispersed by mild agitation b fineness of dispersion in print paste during printing there must be no particles of print paste remaining on the printing screen c depth of embossment the pile height is measured at adjacent embossed and unembossed locations by means of a thin steel ruler marked off in 1 64 inch 0 4 millimeter intervals and the percentage embossment calculated therefrom any method of measurement is appropriate so long as it is standardized from operation to operation and is reproducible to about 1 64 inch i e the depth of embossment measurement should be reproducible to u00b1 about 3 d harshness of shrunk fibers the harness of the embossed carpet pile without protective agent is compared with that of similar embossed areas treated with protective agent and with the unembossed carpet pile by feeling with the finger tips reductions in harshness are quite apparent using this.
