Abstract
A mulch blanket includes randomly oriented organic fibers held by a non-toxic biodegradable polymer binder. A method of forming the mulch blanket includes the steps of randomly laying short organic fibers in an elongated pile along a predetermined path and arranging the top exposed surface of the pile to be flat. A non-toxic biodegradable polymeric binder is then sprayed over the top exposed surface, curing the binder, and then the blanket is peeled off the pile.
Claims5
A non-woven mulch composite blanket adapted to be laid on a ground area comprising a sheet-like member made up of randomly oriented organic fibers each having a length not exceeding 2" and a binder of a non-toxic biodegradable polyvinylacetate copolymer such as to form a self-supporting sheet.
A method of manufacturing a non-woven organic mulch blanket comprising the steps of randomly laying short organic fibers in an elongated pile along a predetermined path and arranging the top exposed surface of the pile to be flat, spraying a non-toxic biodegradable polyvinylacetate copolymer binder on the top exposed surface, curing said binder, and peeling off the so-formed blanket from the pile along said path.
