Encapsulation using polymers to bind to and trap dirt found in the carpet. The polymer solutions are applied by rotary machine, brush applicator, or compression sprayer. Once the residue dries it is vacuumed immediately.
Encapsulation also avoids the drying time of hot water extraction, making the carpet immediately available for use. However, encapsulation does not flush out contaminates found in the carpet as well as hot water extraction.
