Abstract:

The invention relates to a method for preparing a moisture barrier fabric comprising needing the fabric in a direction substantially opposite to the advance direction of the fabric with barbed needles to increase the density of the fabric by entangling the fibers thereof, open-width washing of the needled facecloth fabric with a detergent and sodium carbonate to further increase fabric density by allowing the fabric to neck down or bulk at a substantially random rate, coating one side of the fabric with at least one coating of a latex formulation for use in forming the backcoating of the moisture barrier fabric, comprising a (meth)acrylic acid urethane copolymer having a curing temperature of approximately 250 to 275 F. , and immersing the dry moisture barrier fabric, including the latex backing, into a bath of fluorochemical and solution containing about 10 to about 15 wt % polyurethane, and removing excess fluorochemical from the treated fabric.

Abstract:

Articles of manufacture that are sustainably recyclable and related methods are provided. The article can include a first element having a first polymeric material and a first physical parameter and a second element having a second polymeric material and a second physical parameter. The first polymeric material of the first element and the second polymeric material of the second element are substantially chemically similar while the first physical parameter of the first element and the second physical parameter of the second element are physically different. Methods for manufacturing sustainably recyclable articles are also provided.
