Abstract (en)

[origin: WO9706393A1] Bulking unbulked nylon carpet (55) having a pile side and a backing side is accomplished by heating the carpet to between 90 and 150 DEG C, then cooling the carpet to a temperature below 60 DEG 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.
