Acronym for Through Air Dried, which is a special tissue papermaking technology that produces desirable lower density for the same strength, resulting in better bulk, absorptive capacity,and softness for the same amount of fiber ( basis weight). The TAD fabric that carries the paper through this part of the paper machine leaves a characteristic impression in the tissue paper that looks like very fine and very faint embossing (see micro embossing). , which comes from the TAD fabric that carries the paper through this part of the paper machine. This technology is being used on bath tissue and paper towels, but only rarely (if ever) on paper napkins or facial tissue. More conventional tissue papermaking technologies include: Light Dry Crepe (LDC) and Heavy Wet Crepe (HWC).
