ABSTRACT:
A wave dampening batt for use inside a waterbed mattress is made by intimately mixing a multiplicity of short, non-woven fibers of a first type and a multiplicity of short, non-woven thermal bonding fibers. Raising the temperature of the mixture of fibers above the melting point of the thermal bonding fibers yet below the melting point of the fibers of the first type and then lowering the temperature below that melting point causes the thermal bonding fibers to join the fibers of the first type together throughout the wave dampening batt. A waterbed mattress having a batt made in accordance with this method is also disclosed. The fibers of the first type may be solid or hollow with closed ends, the hollow fibers with closed ends providing buoyancy for the batt. The fibers of the first type may also be lobed or unlobed, the lobed fibers having improved resiliency so that the batt recovers more of its thickiness after compression than a batt made of unlobed fibers of comparable size and denier.
