12376634 · 2025-08-05 ·

A coating fabric and method of manufacturing the same are provided. A coated fabric includes a base coating layer. The base coating layer defines a smooth coating to resist liquid penetration to the fabric. The coated fabric also includes a middle foam coating layer that is deposited on at least a portion of the base coating layer. The middle foam layer defines a middle layer foam density and is configured to absorb at least a portion of liquid. The coated fabric further includes an outer foam coating layer that is deposited on at least a portion of the middle foam coating later. The outer foam layer defines an outer layer foam density and is configured with holes to allow liquid to penetrate to the middle foam layer. The middle layer foam density is less than the outer layer foam density. A corresponding method of manufacturing is also provided.
