Attempts have already been made to separate out vacuum-deformed coated jewelery products.

Other goals and benefits proceed from the following Description, which is for illustrative purposes only and is not intended to limit the invention in any way,

According to the invention, an improved coated fabric is created in which a fabric substrate is connected to two bulk layers, namely a first layer of at least one thermoplastic, synthetic, resinous coating that adheres to the fabric substrate, and a second bulk layer that forms a whole with the first mass layer or adheres to the remaining exposed surface of the fabric substrate and consists of a flexible, thermoplastic, synthetic, resinous coating with a largely exposed surface. The two ground layers have to gene in their composition, in their molecular weight oüer the like. Such sufficiently different that the first ground layer has a üesaiii'Gschmelztemperatur that at least about 20 ⁰ F is below the 'temperature at which the second ground layer, a plastic ErIII owns.

The exposed major part of the surface of the second bulk layer can be embossed to any depth

However, the tile depth is preferably less than the thickness of the layer and is at least 25.4 Ii, the depth of conventional coatings usually being between 25.4 and 304.8 tx (1 to 12 mils) fluctuates-. The first skin layer adheres directly to the fabric and must be of sufficient thickness to hold the entire coated fabric in a desired ionization after vacuum forming.

The actual thickness of the first bulk layer can vary significantly. The minimum effective thickness depends on the junction and nature of the second liner layer, the amount of expansion that occurs during vacuum forming _, or the like. In view of the total coating that is adhered to the fabric, it is usually preferred that the first bulk layer be about 40 to about 70% based on the total weight of the coating, so that the second void layer, which is usually embossed, is about 60% to about $ 30 based on the total weight of the coating. The percentages of one not versus the other can vary depending on individual needs.

In the practical implementation of the invention, it is a precondition that the second layer of mass forms a whole with the first layer of mass and adheres to it, but the invention also includes the case that the second layer is attached adheres to the remaining exposed surface of the fabric substrate.

For the sake of simplicity, the first and second bulk layers are hereinafter referred to as first and second Plating referred to.

For the purposes of the present invention, it is essential that the Gesanitsciimelztemperatur of the first coating is at least about 2O ⁰ F under the l'emperature, wherein the plastic memory of the second coating has a grain loss. The reason for this is that the total melting temperature, which differs from the plastic memory, provides a coated fabric which can be vacuum deformed to a dimensionally stable state without at the same time destroying any indentation present on the second coating. !

The heating of the coated fabric is controlled so that by the time the coated fabric is forced into intimate contact with the mold, the first coating is at a temperature that is at least substantially as high as its total melting temperature while the second coating has a temperature which is sufficiently low that its ₉ PLA λ stisches memory to is not capable of eliciting a significant physical change in the coating.

Numerous examples are known of synthetic resins that can be used to make coated fabrics. These synthetic resins can generally be described as organic materials obtained by polymerization or condensation of, e.g. ^T or less often three simple connections can be made. The properties of synthetic resins are mainly due to their composition, their manufacturing method and the additives added to them. Suitable examples of synthetic resins which can be used are polyvinyl chloride or copolymers of this compound, for example "Geon" vinyl resins, which are described by B.3F. Goodrich Company manufactures "Marvinol" resins manufactured by the US Rubber Company, "Trulon" resins manufactured by Thompson Chemical Company, and chlorinated polyethylene resins marketed by Allied Chemical Company . The total melting temperatures of these resins can be determined from books or by means of simple experiments, so that appropriate combinations are possible. It is preferable to use polyvinyl chloride in practical jurisprudence.
