Abstract
<PICT:0784423/IV (a)/1> <PICT:0784423/IV (a)/2> In a method in which thread is fed in a path of flattened helicoidal form, each ascending portion is hydraulically separated from parallel ascending portions of thread and treatment liquid is fed, and excess liquid removed, at an at least single common point of each ascending portion of the thread so that portions above the common point are subjected to the action of the liquid fed thereto at this point and the portions below are subjected to the action of at least part of the excess liquid removed at such point and re-fed thereto. As shown in Fig. 7, treating liquid is fed to pipes in a conduit 23 which feed the liquid to tanks 24. The liquid is fed from the tanks by capillary action along rods 25 to a channelled plate 12 along which the thread is passed. A series of tanks holding different treating liquids may be used to feed the channels. Excess liquid is removed from the thread and fed to the channels by ridges 14 on the plate. A scraper 26 also removes excess liquid and delivers it to the appropriate tank 24. Excess liquid leaving the plate is collected in a tank 28 connected to recovery channels. As shown in Fig. 5, a viscose mixture is driven by a gear pump through a filter 2 to a spinneret 3 into a coagulating bath B. The rayon fibre from the bath is stretched by passing it over driven glass rollers 4, 5 and then passed through a thread guide 8 and over rollers 9, 10 and 11. The axes of rollers 9 and 11 are askew and slightly inclined to the vertical. The axis of roller 10 is parallel to the axis of roller 11. To produce a series of helical windings initially, one end of the thread is secured to an elastic belt which is passed round rollers 9, 11 which are rotated to form a series of windings positioned by a rotatable toothed hackle. The thread is wound over rods 19, 191 mounted on eccentrics to hold the threads away from the channels of the plate during winding. After winding the rods are retracted so that the thread engages the series of ridges 14. The plate may be heated by hot water or electrically. The treated thread is wound on a spinning box 30 or on to bobbins. The treating liquids may be such as are used for washing, desulphurizing, bleaching, dyeing, soaping, dressing or sizing. The hackle 21 may be replaced by oscillating thread guides and the hackle 26 by an upper ridge 14. The plate may be movable away from the threads and the tanks 24 may be incorporated.
