What can high alkalinity above 10 pH harm in carpets?

High alkalinity in carpet cleaning solutions can indeed have a detrimental effect on acid dye blockers and dye sites. Carpets are often manufactured from various fibers, and many of these fibers are dyed with acidic dyes that have specific pH tolerance levels. When the pH level of the cleaning solution exceeds the threshold of 10, it can disrupt the chemical bonds of these dyes, leading to fading, bleeding, or discoloration.

The presence of acid dye blockers and dye sites is crucial for maintaining the color integrity of the carpet. If the alkaline conditions alter or damage these components, the carpet may suffer irreversible color loss or uneven dye distribution. This can significantly impact the overall aesthetic and value of the carpet.

In contrast, while high alkalinity can also affect other aspects like fiber strength, pile density, and colorfastness, the most direct and immediate adverse effects at elevated pH levels are seen regarding acid dye sites and blockers specifically designed for synthetic and natural fibers dyed with acidic dyes. Understanding this relationship is essential for carpet cleaning technicians to ensure the preservation of color and quality in the carpets they service.
