In the 1990s, new polymers began literally encapsulating (crystallizing) soil particles into dry residues on contact. In the conventional cleaning process surfactant molecules attach themselves to oily soil particles, suspending them (emulsification) so that they can be easily rinsed away. Surfactant (detergent) molecules and emulsified soils which escape being rinsed away, remain in the fibre and continue to attract soiling. Encapsulators are specialty detergent polymers which become part of the detergent system. As drying occurs (20-30 min. drytime), after cleaning, these encapsulators bind the detergent molecules and residual soils in a brittle, crystalline structure. Detergent and soil particles can no longer attract other soils and are easily removed by dry vacuuming. In addition to binding the detergent and soil residues the encapsulation chemistry coats the clean fibre with the same brittle film. This reduces the fibre’s affinity for oily and particulate soils. As this brittle film "breaks away" and more soil is removed, the appearance of the fibre improves as opposed to soiling more rapidly. Products which also employ fluorochemical technology, display dramatically extended anti re-soiling time periods.
Cleaning solution is applied by rotary machine, brush applicator, or compression sprayer. Dry residue is vacuumable immediately (20-30 min. drying time), either separately or from a built-in unit of the cleaning-system machine.
