Abstract
A piano forte hammer includes an elongated head having a nose defining side surfaces, and a felt body extending about the nose portion, with tail portions of the felt body affixed upon the side surfaces. The tail portions contain a predetermined measured amount of an acrylic copolymer. In preferred embodiments, the hammer is formed by a process including the steps of: providing a first volume of an aqueous solution containing the predetermined measured amount of acrylic copolymer in a slot, disposing a first tail portion of the felt body in the solution, allowing the felt body to draw essentially all of the solution from the slot by natural wicking action, providing a second volume of an aqueous solution containing the predetermined measured amount of acrylic polymer in a slot, disposing a second tail portion of the felt body in the solution in the slot, and allowing the felt body to draw essentially all of the solution from the slot by natural wicking action.
