Zoned Pile Density Cleaning Textile for Uniform Contact Pressure

The cleaning textile implements local quality by varying the pile density across different regions of the cleaning surface. Specifically, the central region has a lower pile density while the peripheral regions have a higher pile density. This non-uniform pile density distribution compensates for the uneven contact pressure that occurs during wiping operations, where the center typically experiences higher pressure. The result is a more uniform cleaning performance across the entire surface.

The invention applies local quality by creating distinct pile density zones: a central zone with lower pile density that accommodates higher contact pressure, and peripheral zones with higher pile density that experience lower contact pressure. This spatial variation in pile density ensures that each region is optimized for its specific pressure conditions, balancing mechanical stress distribution and preventing uneven wear while maintaining high cleaning efficiency in the central area.

The invention implements local quality by decreasing the pile density in the central area rather than increasing it. This counterintuitive approach allows the softer, lower-density central region to conform better to surfaces under high contact pressure, distributing the pressure more evenly. The peripheral regions maintain higher pile density for effective dirt pickup where contact pressure is naturally lower, achieving both good dirt pickup capability and uniform cleaning across the surface.
