Abstract: A method of making a foam backed drapery fabric or the like having good textile properties, and the fabric so produced. A wet foam backing is applied to a moving web of fabric, flocking is optionally applied to the wet foam backing, and the backing is at least partially dried without significant curing.

Where a curing oven containing rollers is utilized the foam backing is then dried, and then passed to the curing oven. The final fabric has good textile-like feel, softness, drape, abrasion resistance, and appearance characteristics, and the embossed backing is capable of recovering in five seconds to one minute after 3,000 psi has been applied for five minutes.

Abstract: An ornamented article of clothing constituting a fabric substrate which forms at least a part of an article of clothing has applied to it in a pattern, with the aid of a stencil, an area of predetermined configuration such as a design, a character or a phrase in the form of an adhesive coating composed of a film-forming solid and a liquid solvent.

While the coating still is wet there are applied to the coating particles composed of a plastic material which is attackable by one or more constitutents of the still-wet adhesive, specifically the solvent or a plasticizer incorporated in the plastic solid. This attack on the surfaces of the particles causes the particles to bond to the adhesive coating.

The platen is mounted on a rotatable shaft and diametrically opposed to a similar platen in an uppermost position which is operatively associated with a screen printer. In use, a printed substrate is flocked while an additional substrate is being printed.
