摘要： 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.The method is particularly suited for production of patterned pile fabrics containing thermoplastic pile yarn components, whereby the height of the pile yarns in the areas contacted by the streams may be reduced by varying amounts, depending upon the pattern-controlled introduction of cooler fluid into the heated fluid streams.Multiple height, surface-patterned products produced by the aforementioned method are also disclosed.
