摘要： The disclosure relates to techniques for high efficiency drying of wet-processed tubular knitted fabric. The wet tubular fabric is initially spread to flat form and then guided in a controlled manner over a so-called Mach nozzle, at which high velocity gaseous medium, usually steam, at speeds approaching the speed of sound and above, is discharged directly through the fabric, which is maintained in tension as it passes over the nozzle outlet. The thus treated tubular knitted fabric, now with a greatly reduced liquid content, is then immediately directed over a second spreader device, which distends the fabric widthwise to a predetermined, uniform width, to restore the fabric width lost during wet processing and during the relatively high tension nozzle treating operation. In this damp, geometrically stabilized condition, the fabric may be directed immediately into an otherwise conventional tensionless dryer for tubular knitted fabric, where the necessary final drying operations are completed. More typically, the fabric is loosely folded and then dried later. Significant production economies are realized pursuant to the invention, both in energy savings and labor savings, as well as reduction in capital equipment costs. The process also makes wet-on-wet foam processing relatively attractive for cetain tubular knitted fabrics.
摘要翻译：本发明涉及湿法处理的筒状针织物的高效干燥技术。湿式管状织物最初铺展成平面形状，然后以受控的方式引导到所谓的马赫喷嘴上，高速气态介质（通常是蒸汽）以接近声速和高于其速度的速度直接通过织物，当其经过喷嘴出口时保持张力。如此处理的筒状针织物现在具有大大降低的液体含量，然后立即被引导到第二扩张器装置上，第二撒布装置将织物宽度方向延伸至预定的均匀宽度，以恢复在湿处理期间和相对高压喷嘴处理操作。在这种潮湿的几何稳定状态下，织物可以立即被引导到用于管状针织物的另外传统的无张力干燥器中，其中必要的最终干燥操作完成。更通常地，织物松散地折叠，然后稍后干燥。根据本发明，在节能和劳动力节约方面实现了重要的生产经济，以及资本设备成本的降低。该工艺还使湿式湿式泡沫处理对于et管状针织物相对有吸引力。
