Abstract
Tubular knit goods including natural fibers and synthetic elastomeric fibers are steam treated and then circularly expanded and heat-fixed while being transported vertically downwardly over a circular spreader in a heat fixing chamber. The goods build up a buffer or excess material reserve on the conical feed section of the circular spreader, either by using a greater transport velocity into the feed section than that out of the feed section and along the spreader, or by starting to feed the goods into the feed section for a time before starting to draw the goods out of the feed section and then transporting the goods to and from the feed section at the same velocity. The goods relax in the buffer. Transporting the goods vertically downwardly over the circular spreader during the heat-fixing uses gravity advantageously, and reduces tension in the goods.
