Abstract

<PICT:0491038/IV/1> In the manufacture of artificial silk threads from cuprammonium cellulose solutions by the funnel stretch - spinning method, several separately spun thread bundles 3111, 4111, 5111 each having a fine total titre are, before acidification but after leaving the spinning funnel, and while still tacky, guided together to form a composite thread 7. Suitable apparatus for carrying out the process comprises a large number of small funnels 1, 11, 111, 2, 21, 211, each producing threads of 10-25 denier and arranged in two rows offset with respect to one another. The arrangement permits higher spinning speeds and greater uniformity in the product. The guiding together of the small filament bundles may be achieved with the aid of narrow thread guides 6 which may be V-shaped and which exert a certain degree of pressure on the threads. The composite threads pass then through the acidifiers 8, over thread guides 9, 10 and on to reel 11. They have a multi-lobular cross-section, e.g. as shown in Fig. 4.
