Abstract
Abstract A mat for use as bedding material in an animal stall, comprises at least two felt-like layers of textile material (1,2) held together by multiple needleperforations (9) with the top surface of the top layer of textile material being impregnated with a substance (4) suitable for forming an abrasion-resisting skin. The impregnating substance is preferably a heat shrinkable copolymer of styrene and acrylic ether. Natural or synthetic fibers may be used for the felt-like layers of textile material. The fibres may be long and continuous, or alternatively they may be a tangle of short fibres. Although particularly intended for use with stalled cows, the floor covering may be used in other forms of stabling, with other species of animal, and indeed in quite other locations such as public halls and the like.
