What is one possible outcome of pile reversal in carpets?

Pile reversal, often referred to as “shading” or “water marking,” can result in a noticeable difference in how the carpet's fibers reflect light, leading to the effect where certain areas seem to have different color intensities or patterns. This phenomenon occurs when the carpet pile is flattened in different directions, causing a visual discrepancy that can appear similar to pooling.

When the pile is reversed in specific areas, it can create an optical illusion whereby some parts of the carpet look darker or lighter than surrounding areas as the light hits the fibers at various angles. This situation is also exacerbated by the cleaning method used, where the water or cleaning solutions may impact the direction and appearance of the carpet fibers. Understanding this can help technicians not only diagnose issues with carpet appearance but also guide appropriate maintenance practices to prevent such occurrences in future cleaning sessions.

Other possible outcomes like color change, increased durability, or reduced maintenance do not accurately describe the immediate and observable effects associated with pile reversal, making them less relevant in this context.
