Permanent Pile Reversal Shading
What is it?
Permanent Pile Reversal Shading is a phenomenon that can appear in any cut
pile carpet. Its occurrence is random and its causes are largely unexplained. It
is also commonly referred to as watermarking, pooling or puddling. A cut pile
carpet that has ‘shaded’ will show areas lighter or darker than the surrounding
carpet pile. This variation is caused by the reflection of light from pile tufts
which come to lay in different directions.
Visually, Permanent Pile Reversal Shading is not unlike the brushed appearance of other cut pile fabrics such as suede, velour and velvet, although the appearance change in a carpet that has ‘shaded’ will be permanent.
Permanent Pile Reversal has been associated with cut pile carpet for many
years, in fact well before the advent of machine made carpets. Despite extensive research and development of methods and techniques to minimise the occurrence of shading, the characteristic is not predictable.
As Permanent Pile Reversal Shading will have some impact on the appearance
of a carpet, consumers should consider the possibility that it may occur when
buying a cut pile carpet.
