Abstract
A treated fabric has a scoured fabric with face side and back side; a non-foamed color-masking composition disposed on the back side; drying the resulting coated fabric to form a dried color-masking composition at 5-75 g/m2; and D) heat-setting the scoured fabric between steps A) and B), or heat-setting the coated fabric during or after step C). The color-masking composition has a tinting component and film-forming polymeric binder of Tg less than 25° C. Visual perception is reduced on the uncoated face side of the treated fabric when a cured, crushed, and dried foamed opacifying layer has been disposed on the back side. Reduced visual perception is measured by a ΔE value as determined from ΔL*, Δa*, and Δb* CEILAB color values, to be <2, compared to visual perception on the uncoated face side of the same treated fabric when the cured, crushed, and dried foamed opacifying layer is absent.
