Definitions
- the present invention relates to a method for high-speed spinning a family of thermoplastic monofilaments with a single titer of 1 to 30 dtex and a device for carrying out the method, as well as the monofilaments produced thereafter.
- Fine monofilaments up to about 33 dtex are spun at spinning speeds of less than 1000 m / min, cooled with blown air, wound up and drawn separately in a second operation at about 750 m / min.
- the object of the invention is to provide a process for the production of fine monofilaments which achieves and / or improves the properties of known monofilaments without a separate stretching process at high winding speeds.
- Another object is to vary the method in such a way that desired properties of the monofilaments can be achieved by the setting parameters of the device.
- the above-mentioned object is achieved in that the melt-spun monofilaments are passed directly over a friction element during the cooling by means of blown air ", then are spin-prepared and wound up.
- the winding speed is 3000 to 6000 m / min., Preferably 4000 to 5000 m / min.
- thermoplastics such as all kinds of polyesters, polyamides, in particular those known as nylon 66 or nylon 6, and also polyacrylic, polyvinylidene fluoride, made of polyethylene or polypropylene.
- the device for carrying out the method essentially consists of a friction element which is arranged between the spinneret and the device for the preparation application.
- the friction element is preferably fork-shaped formed, rotatable and movable in its distance from the spinneret.
- the two opposite friction surfaces, an upper friction surface and a lower friction surface are arranged axially parallel.
- a friction element which has been set and fixed once at a distance from the spinneret can be rotated about its axis continuously or in fixed steps in such a way that a desired tension can be provided on the thread lying between the friction surfaces.
- the gradual adjustment has the advantage that the desired positions can be precisely re-adjusted at any time and a constant, reproducible thread tension is guaranteed.
- the friction element can consist of a plurality of pins which have a cylindrical but also an oval surface. However, other bodies with curved surfaces can also be used.
- a distance of the friction elements from the spinneret that is 20 to 280 cm, depending on the desired final titer of the monofilament.
- the twist angle ⁇ between the thread path and the common axis of the friction element surfaces should be 0 to 40 degrees of angle and the wrap angle of the friction element / monofilament should be 50 "to 150 *.
- the monofilament produced by the process should also meet the following conditions. a) an elongation of 20-45% b) a strength of 36-60 cN / tex c) a cooking shrinkage of 2-15% d) an irregularity of ⁇ 1% Uster and e) a uniform and round cross-section.
- the invention is to be illustrated schematically on the basis of a drawing.
- Fig. 1 The arrangement of the friction elements according to the invention in the region of a blow shaft with several monofilaments.
- a spinneret is shown schematically at 1 in FIG.
- a friction element 3 is arranged between the spinneret 1 and a winder 7.
- the height of the friction element 3, as indicated by arrows, is adjustable.
- the friction element 3 consists of a friction surface 4 and a friction surface 5, which are arranged around an axis 8.
- the friction element 3 is rotatable so that a monofilament 2 or a family of monofilaments which is passed between the friction surface 4 and the friction surface 5 and which is represented by the monofilaments 2 and 2 'delimiting the thread family are subjected to a frictional force can.
- a device 6 for applying a spin finish is provided between the friction element 3 and the winder 7.
- Fig. 2 the rotatability of the friction element is indicated by arrows.
- Fig. 2a the monofilament 2 passes between the friction surface 4 and the friction surface 5.
- Figure 2b the friction element 3 and the friction surfaces 4 and 5 are shown in side view.
- FIG. 3 the height adjustment of the Reib comprise ⁇ 3 as a whole unit and that of the friction surface 5 compared to 4 is indicated by the double arrows.
- Fig. 3a the thread leads between the frosted surface 4 and the friction surface 5.
- Figure 3b is a side view of Figure 3a.
- Fig. 4b is a side view of Fig. 4a.
- a group of threads emerges from the spinneret 1, consisting of the monofilaments 2, 2 'delimiting the group, which run parallel through the friction element at high speed and are stretched over the friction surface 4 and the friction surface 5 by means of the winder 7.
- a suitable spin preparation 6 is applied on the path between the friction element 3 and the winder 7. If necessary, a godet can also be arranged between the friction element and the winder.
- the resulting monofilament is a finished product for further processing.
- Polyester with a Vl of 74 dl / g and a melt temperature of approx. 287 * C is extruded through a spinneret 1 x 6 / 0.33 / 4D and drawn off at a speed of 5000 m / min and blowing air with 0.25 - 0.4 m / s cooled.
- the distance between the spinneret and the friction element is 30-160 cm, depending on the titer.
- a spinning preparation is applied to the thread at a distance of h + 40 cm.
- the adjustment of the friction elements (Fig. 2) was carried out in three different stages, 0 ⁇ , 20 * and 40 °, measured against the direction of the thread. The measurement results are shown in Table 1. (Winding speed 5000 m / min)
- the wrap angle is (friction element according to FIG. 2) when in position
- Table 2 shows the yarn parameters of a test with a winding speed of 4000 m / min. summarized. Other spinning conditions as in Example 1.
