    摘要： A process for simultaneously drying and heat treating wet spun fibers of greater than 20 percent water based on weight of dry fiber material supplied continuously in multiple wraps around a pair of rolls in a heated zone, at a tension of 0.2 to 6 grams per denier at the beginning of the zone, with gas jets extending around each of the rolls for about 45 to 180 to direct turbulent gas at a temperature of 200 to 660 C against the fibers under tension in the zone until the residual moisture in the fibers is from 0.5 to 10 percent water based on weight of dry fiber material.

    摘要： A method and apparatus for reducing the moisture content of wet yarns are disclosed. Wet yarn is supplied to a pair of internally heated drier rolls which contact and spirally advance the yarn along the rolls to progressively dry the yarn. Heat is supplied to the rolls at a rate in excess of that necessary to reduce the moisture content to a predetermined level. Water is sprayed on areas of the rolls not in contact with the yarn to cool the contact surfaces. The moisture content of the yarn is measured subsequently to discharge and a signal is produced which corresponds to the moisture content. In order to achieve a desired moisture content, the spraying of water is controlled in response to the signal produced by measuring the moisture content so that the yarn discharged from the rolls approaches the predetermined level.
