Abstract: A flocked polyurethane foam fabric and method for manufacturing the same for which flock fibers imbedded in an adhesive on the foam are permanently flattened and entangled. Dry ink is transferred onto the flock fibers at the same time that flattening of the fibers is taking place. The flock fibers are thermally set into their flattened state along an outer surface of a polyurethane foam base of the fabric. Flattening the flock fibers causes the entanglement of the flock, thereby improving the hand, appearance, drapeability, abrasion resistance, water repellency and heat insulation qualities for apparel items over that of unflattened flock fibers.

Abstract: It is possible to produce denim fabric suitable for manufacture into garments that have the look and feel of washed and tumble dried garments, practiced in a relatively simple and quick manner. Denim fabric is treated to raise the warp yarns so that the warp yarns are adjacent the face of the fabric and positioned so that they can be rubbed and abraded to loosen the surface fibers; and then effecting abrading and rubbing of the tips of the warp crimp so as to duplicate the surface abrasion of washing and tumble drying without making a napped or brushed type finish or face. The abrading action may be practiced by sanding utilizing a fine sandpaper in the range of about 50-100 grit, employing a 9-roll T-Ralph sander with 2 to 6 rolls running at a speed of about 50 ydm.

Abstract: A method of producing surface height patterned materials by application of streams of pressurized, heated fluid into surface areas of a relatively moving material having thermally modifiable surface components. The heated fluid streams are selectively activated and deactivated in accordance with pattern information to strike selected surface areas of the material to thermally shrink and compact the surface areas by a desired amount. Heated fluid stream flow is controlled by use of cooler pressurized fluid which is selectively directed into the heated fluid stream flow to block the same from striking the surface of the moving material. The temperature of selected of the heated fluid streams striking the material is controllably varied by rapidly introducing small amounts of cooler fluid which blend into the heated streams to correspondingly vary the height reduction of the surface of the material.
