METHOD AND APPARATUS FOR FLOW TREATMENT OF HEATED AND PRESSURIZED FLUID TO SUBSTRATE MATERIAL

摘要

PURPOSE: To provide a method and an apparatus for producing a finer uniform pattern in a high yield at a high speed in forming a pattern by spraying, for example, high-temperature pressurized air on the surface of continuously moving thermoplastic woven fabric. CONSTITUTION: In perpendicularly applying high temperature pressurized air in a sheetlike state to the surface of a fabric, finely separated valves are opened and closed and a low-temperature air is jetted to a plane perpendicular to the air sheet, namely in parallel with the surface of the fabric and a high- temperature pressurized air stream at the parts are deflected to prepare a pattern. Simultaneously, the fabric just before the processing is preheated by a mixture of the high-temperature air and the low-temperature air to a temperature a little lower than the melt temperature of the fabric to attain a pattern formation of quick response and to raise the processing speed. A structure for showing an operator the result of processing after the processing is over is made and the operator can notice production of defective goods and decrease a loss.
