    • 专利摘要:
    The conventional spandex spinneret has two rings of equally spaced grouped orifices, each filament being formed by coalescence of the extrudate from the grouped orifices. A spandex spinneret having the holes of the orifices of each group of the outer ring of groups more closely spaced than those of the inner ring or groups has eliminated the power differences between inner and outer threadlines. The closer spacing within each group of the outer ring of groups also increases the spacing between groups, thereby reducing filament migration.

    This invention relates to the manufacture of artificial fibers, in particular, to the production of mixed yarn,
    The purpose of the invention is to improve the quality of the yarns by leveling the load on the yarns.
    The drawing shows the proposed die. The filler 1 contains a plate 2 with groups 3 and 4 of holes 5 - and 6, which are located along concentric rings 7 and 3. Holes 5 and 6 each of Groups 3 and 4 are located both circumferentially and radially. The distance of the meldu holes in each group


    to
    ne along the circumference d, and dg, so along the radius d 5 and d 4. is the same for all groups of the corresponding ring ,. The distances d, and dj can be in the following ratios: d 7 d d2Hd d. Preferably, in each section: there were four holes each, with two on the outer ring, preferably, twenty groups of holes, and four groups of holes on the inner ring.
    .
    In this case, d, and d 2 less dj, and
    PRI me R. From the prepared spandex spinner through a die with 64 extrusion holes DIR1TOT 16 glued threads. In each Group 3 and A there are four holes 5 to 6 each. Sin holes are located on plate 2 along concentric rings 7 and 8. In each Group of the outer ring, the distance between the holes is approximately 0.52 inches (5.1 mm) j, and the inner ring 0.39 inches (9.9 mm). The extrusion was carried out at a speed of 6.2 lb / h and winding at a speed of 730 m / min. Thread number 10 was obtained. Of the 16 strands, 12 were obtained from the openings of the outer ring, and 4 - from the inner ring. The load on the filaments (T 300) t located on the inner ring is 1.51.89, and on the outer ring 15.90. The load difference is 0.06 tonnes.
    Since the frequency of moving the threads between the groups and the drying conditions of the inner and outer groups of the threads increase with the increase in the number of products: this leads to different loads on the threads, which adversely affects the quality of the threads and their appearance.
    The preformed die helps to level the loads on the threads of the outer and inner groups, which helps to improve their quality.
