Abstract
Abstract A fabric of which at least 10% by weight comprises polyester fibers, which fabric is durably soil releasing on laundering and which is useful for preparing the facing sheets of mattress pads. This fabric is finished with a soil release finish consisting essentially of a cured mixture of a fluorochemical soil release agent, an adhesive binder and a cross-linking agent.
