Abstract

1,144,238. Melt spinning chimney. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTITUT MASHIN DLYA PROIZVODSTVA SYNTHETICHESKIKH VOLOKON. 6 Dec., 1966, No. 54550/66. Heading B5B. A melt spinning chimney is provided with a chamber for trapping and drawing off volatile matter released from the filaments travelling downwards through the chimney, said chamber being situated on the upper portion of the wall of the chimney opposite the wall of the chimney through which a stream of air enters the chimney and travels across it and being provided with at least one slot-shaped opening in its wall facing the stream of air. In the embodiment of the apparatus of the invention, a melt-spinning chimney assembly comprises a blow-box 1 (Fig. 1), a chimney 2 communicating with the blow-box, and a trapping chamber 3 situated on the upper portion of the chimney 2 on the side thereof opposite the air flow inlet and has a wall 4 (Figs. 1, 2 and 3) inclined with respect to the direction of travel of the air flow across the chimney 2. The wall 4 is U-shaped in cross-section (as shown in Fig. 3, which is a top view of the trapping chamber) and is provided along its length with a slot-shaped opening 5. The air containing vapour evaporated from the hot filaments extruded downwards from the spinneret 16 in the spinning head 15 and passing through the openings 5 is removed from the chamber 3 through the pipe 11 by means of a fan (not shown). The upper and lower walls 6 and 7 of the chamber 3 and its wall 10 on the outlet side of the chamber are impervious while the inlet side of the chamber facing the blow-box 1 is open. The chamber 3 is attached to the side wall of the chimney 2 by fixing members 14. The chamber 3 is provided with an inlet pipe 8 through which water is supplied to dissolve any crystals of volatile impurities deposited in the chamber and a bent plate 9 attached to the wall 10 to distribute the water uniformly in the chamber. The direction of travel of filaments and cooling air in the chimney is indicated by the arrows A and B respectively.
