Corn rowing is a condition that may appear on carpets before or after
cleaning. It looks like distinct rows of tufts have fallen over the tips
have become embedded in the carpet pile. It usually forms in a regular
pattern. With ever fourth of fifth row bending over, as might happen in
a row or corn. The condition may develop in traffic lanes and under doors
that scrape the carpet as they are opened and closed. It generally occurs
perpendicular to the traffic direction.
Corn rowing appears most commonly on carpets made from fine, soft yarns,
with a fairly high, cut pile. In most cases the overall density is not
adequate to support the yarns and keep them upright. If there is too much
space between the rows the tufts may be bent over when they are walked
on. Soft, fine yarns do not spring back as readily as other carpet yarns
made from heavier and denser fibers.
Although cleaning the carpet may bring the problem to light, it is not
the cause of the distorted pile surface per se. Corn rowing is simply
an inherent characteristic of certain carpet constructions. Vacuuming
and raking the carpet perpendicular to the traffic patterns may help in
some cases. In extreme situations, we suggest you contact the manufacturer.
