The carpet has the characteristics of soft texture, comfortable foot feeling and safe use, and is particularly suitable for floor decoration in the bedroom, living room and study room of a family. The carpet can achieve satisfactory decoration effect when fully laid or used as partial decoration of the floor in home decoration. The carpet is easy to hide dust and breed bacteria through trampling, and becomes dirtier and dirtier with the increase of use time, which causes human body discomfort and even skin allergy and inflammation. Therefore, the carpet needs to be cleaned after use for a period of time. The carpet is inconvenient to wash due to its thickness and significant increase in water absorption weight during washing. Frequent replacement of new carpets also causes waste of resources and is not in line with the concept of low-carbon and environmental protection.

The surface layer and the bottom layer are detachably connected by the shape and connection structure of the first pile 11 and the second pile 21.
[0039] The detachable easy-to-wash carpet of the embodiment is prepared by the following method:
