    摘要: Bulking unbulked nylon carpet (55) having a pile side and a backing side is accomplished by heating the carpet to between 90 and 150 °C, then cooling the carpet to a temperature below 60 °C. Heating is accomplished by directing heated fluid at the pile side, or both the pile side and the backing side. The heating oven comprises an enclosure (42); tenter clip loop (44) and opposed loop (46) driven by motors (48 and 50), respectively; a plurality of nozzles (52, 54); return inlet (56), blower (58) and a header (59) for circulating gaseous fluids through the nozzles; dampers (60, 62 and 64) and a heat exchanger (65) for heating or cooling the circulating fluid.
