a durable erosion control blanket featuring a novel synthetic fiber filler is disclosed . the erosion control blanket of the present invention addresses the need for a particularly resilient erosion control blanket through the use of a post - consumer , crimped , polyester fiber filler material . in one embodiment , the post - consumer fiber material is of polyethyleneterephthalate readily available in post - consumer form from the recycling of soda bottles . in short , a preferred filler material for the blanket of the present invention would utilize recycled soda bottle material which has been converted into a crimped , highly - resilient fibrous filler . it is , thus , possible to achieve the desired physical and mechanical properties in the erosion control blanket of the present invention while conserving natural resources to some extent by using a readily available post - consumer polymer material .
