CarpetSmart stands as a beacon of excellence in the carpet cleaning industry, especially in bustling cities like Bangkok. With our professional carpet cleaning services, we address various issues that affect carpets, including the perplexing phenomenon of reverse pile shading or watermarking. This post will delve into the intricacies of this issue, explaining what it is, why it happens, and how our cutting-edge technology and techniques make us the best carpet cleaning services near you in Bangkok.

Understanding Reverse Pile Shading and Watermarking

What is Reverse Pile Shading?

Reverse pile shading, also known as watermarking, pooling, or highlighting, is a phenomenon that affects all pile yarn carpets. It creates a permanent change in the carpet's appearance due to the way light reflects off the yarn's sides and tips when the pile lays in different directions. This results in shaded areas that appear light from one angle and dark from another, giving the illusion that water has spilled on the carpet.

This is an excellent illustration of how reverse pile shading occurs. What causes it and how it affects the visuality of the carpet and how the fibres behave and reflect light off of the reversed fibre strands.

Why Does It Happen?

The precise reasons why carpet pile changes direction and creates this shading effect remain somewhat mysterious. However, several factors can contribute to this phenomenon:

  1. Foot Traffic Patterns: High-traffic areas often push the carpet pile away from the center of the path and towards the sides, creating a visible pattern.

  2. Subfloor Irregularities: Uneven subfloors can cause the pile to shift in different directions.

  3. Environmental Factors: Humidity and temperature changes can also affect the pile direction.

It’s important to note that pile reversal is not a manufacturing defect and does not impact the durability of the carpet. It can occur in any type of carpet, regardless of the materials or manufacturing process used.

The Challenge of Addressing Pile Reversal

Once pile reversal has occurred, reversing it is nearly impossible. Brushing or vacuuming might offer temporary visual changes, but these are superficial and the pile will return to its reversed position once subjected to foot traffic again. The visual impact of pile reversal can vary depending on the carpet type:

  • Loop Pile Carpets: These have a lower light-reflecting quality, making pile reversal less noticeable.

  • Cut Pile Carpets with Matte Yarns: These also reflect less light, helping to hide the effects of shading.

  • Boldly Patterned Carpets: Patterns can mask the light reflection variations caused by pile reversal.

Despite these nuances, it is impossible to guarantee that pile reversal will not develop in any carpet over time.

Here you can clearly see the where watermarks are. They are actually fibres that flow in the opposite direction, light is absorbed by some fibres and reflected back by others. This is a great example of what the carpet looks like after years of traffic moving the fibres in different directions. It actually looks very dirty but that is just the absorbed light. So, you could say that the dark patches are in fact fibres that are pointing toward you, and the lighter fibres are pointing away from you reflecting the light back at you.

Again, a great image to show the shaded areas that look like a water spillage, or 'Watermarks'. These are a permanent feature of your carpet now, and no amount of brushing or cleaning will get them to sit straight in the base of the carpet! It is a strange but incredibly common phenomenom that simply cannot be fixed?

In this picture, if you look at the top right corner you will clearly see large dark patches that are definitively permanent reverse pile shading! Sometimes, with our cleaning and because we use counter rotating brush machines that lift the pile, it sometimes makes them even more visible. It is not down to bad cleaning methods, its just that we have now exaggerated the pile that will soon flatten back to their original reverse position after a little foot traffic. I hope this post has helped?
