Dimensional stability of tufted carpets has been a continuing problem in the carpet industry
for years. When a tufted carpet is installed by the stretch-in method, it experiences stress
relaxation over time which can cause the carpet to buckle, wrinkle and become loose with
the only option being a costly re-stretching of the carpet. Analysis of the various
components of the tufted carpet composite structure was performed to identify the role each
component plays in the phenomenon of stress relaxation. A biaxial loading system was
used to test various samples of the primary backing alone, primary backing after tufting (with
tufts), secondary backing alone, and the finished carpet after attaching the backings with
various binder weights per area. The four variables under consideration included primary
and secondary backing constructions, tufting density, and latex weight. A rheological model
that includes representations of each component in the carpet structure was developed and
will be presented in a following paper.
