Quad analysis is useful for analyzing subjective properties. This new approach provides an
efficient route to conducting paired comparisons, the preferred method for quantifying such
properties. A process study taken from the carpet manufacturing industry demon strates the
usefulness of the approach: drawtexturing factors are manipulated to impact commercially
important carpet properties like body, tuft endpoint. and wearability. Quad analysis provides
process direction, whereas traditional sample-to-control contrasts fail to provide any useful
process direction. An extension to quad analysis. quad folding of one quad design into
another, is introduced as an efficient method to rank order the subjective properties of larger
data sets. Its advantage is demonstrated for a series of nylon carpets inserted with a low-
melt yam to improve their initial presentation and wearability.
