Definitions
- the present invention relates to a device for producing a spun Thread from a staple fiber association according to the preamble of claim 1.
- Such devices are known in textile technology and are used in air spinning processes used. Such a device is disclosed, for example, by the document EP 854 214 (equivalent to US 5,927,062), which is shown in FIG. 1.
- the fiber guide element 3 has a fiber feed channel 4 with a helical fiber guide surface 5 on.
- the staple fiber bandage 1 is guided through the fiber guide surface 5, which ends at a fiber delivery edge 6.
- At a certain distance from the The fiber guide element 3, or to the fiber delivery edge 6, is a spindle 7 with a yarn guide channel 8 and an inlet mouth associated with the yarn guide channel 8 9 provided.
- a fluid device for creating a vortex flow around the inlet mouth 9 provided (fluid device not shown).
- the fluid device generates a vortex flow 11 around the inlet mouth 9, or the Spindle 7.
- the free fiber ends 12 are laid by the vortex flow 11 of the staple fiber dressing 1 around the inlet mouth 9.
- a staple thread 10 is thus created in the staple fiber association 1.
- the present invention is concerned with the design of fiber guide elements, as shown in Figure 1.
- the invention is particularly concerned with the design of fiber feed channels and the associated fiber guide surfaces.
- FIG. 1 shows essentially the same components as in FIG shown in Figure 1 (with a change, see Figure 2a).
- the outlet roller pair 2 and the spindle 7 with the yarn guide channel 8 can be seen.
- Analogous to FIG. 1 also shows a fluid device 13 for generating a vortex flow shown.
- the fluid device 13 consists of several bores, one of which Fluid (preferably air) is blown into space 14 under pressure. The blown Compressed air creates a vortex flow around the inlet mouth 9 of the spindle 7.
- the fiber guide element 3a consists of two components.
- FIG. 2a the fiber guide element part 3b of FIG. 2 is shown in a three-dimensional View shown.
- the fiber guide element part 3b not a helical, but a flat fiber guide surface 15.
- the fiber guiding element part 3b has a blunt cone 16 on. The purpose of this cone 16 is to produce a so-called false yarn core. This is to prevent a false twist (twisting of the staple fiber association) from the inlet mouth 9 backwards through the fiber guide element 3 propagates against the nip of the pair of output rollers 2.
- a false twist prevents a real rotation or twisting of the free fiber ends 12 to form a Yarn, because the core of the staple fiber association rotates with the free fiber ends 12 with. This means that the false twist would prevent the fibers from spinning.
- an attempt is made to stop the swirl by the helical one To realize fiber guide surface 5, which a twisting of the staple fiber association 1 against the outlet rollers 2 should be impossible.
- FIGS. 1 and 2 The known prior art of FIGS. 1 and 2 has various disadvantages, which to fix or minimize the device according to the invention tries.
- Another disadvantage is that the one shown in the figures Twist stop can hinder optimal fiber guidance.
- Another critical point of the published or unpublished writings mentioned so far has not been solved satisfactorily, the guidance of the fiber structure between the Clamp line of the outlet roller pair and the fiber guide element (see for example Figure 1 or 2).
- the staple fiber bandage consisting of individual parallelized and untwisted fibers has a relatively low strength, or one relatively low internal cohesion.
- the object of the present invention is accordingly the disadvantages of the prior art Fix or minimize technology.
- the fiber guidance should in particular be such will design that the yarn quality of the spun thread is improved.
- FIG. 3 shows a device for producing a spun thread with an inventive designed fiber guiding element 3c, a fluid device 13 for production a vortex flow 11 around the inlet mouth 9 of a spindle 7 with an integrated Yarn guide channel 8.
- FIG. 3 shows a cross section of the device in parallel to the direction of conveyance of the staple fiber bandage (which is not shown in this figure becomes).
- the fiber guide element 3c shown in the figure has an inventive Fiber guide surface 18 with a deflection point 17.
- the deflection point 17 is in this example by designing the fiber guide surface 18 according to the invention educated.
- the fiber guide surface 18 actually exists from two flat surfaces, the common intersection of which is the deflection point 17 forms.
- This design of the fiber guide surface makes the fibers of the staple fiber association in an essentially flat arrangement guided.
- the fiber delivery edge 6 also contributes to this flat arrangement.
- the deflection point 17 (which is formed here as an additional edge) is dimensioned so that that the fibers of the staple fiber association are deflected such that the free Fiber ends of the fibers, which are in the staple fiber structure, can lift off (see Fig. 4).
- the front as well as the rear fiber ends especially those fibers lifted off that are on the surface of the staple fiber dressing or immediately below. Be at the deflection point 17 both front and rear fiber ends lifted off.
- Free fiber ends are understood to mean those ends that do not lie within the staple fiber structure or are not connected to other fibers are and can be captured by the vortex flow.
- By increasing the number of free fiber ends increases the number of wrapping fibers in the Yarn and the quality of the spinning process itself. Overall, this can be done so increase the yarn quality.
- the design of a deflection point such that the inventive The effect of lifting off the free fiber ends is essential.
- the applicant's international application PCT-CH 01-00569 shows in her Figures and explains in their description an increase in their fiber guide area.
- the design of the fiber guide surface according to the invention surprisingly has a further advantage over the prior art.
- the reduction in the cross section A of the fiber conveying channel 4 within a region has shown that the air volume V flowing through was surprisingly increased.
- the increased air flow V made it possible to substantially improve the fiber guidance between the outlet rollers and the entrance of the fiber guidance element 3c, that is to say in front of the fiber guidance element.
- the number of production interruptions, caused by tearing of the staple fiber association immediately after the outfeed rollers, could be reduced. A measurable improvement in yarn quality was also found.
- the cross sections A of the fiber conveying channel up to the deflection point preferably have an amount of 0.5 to 10 mm 2 , preferably 2 to 5 mm 2 .
- FIG. 3a shows a section along the section lines I-I of the inventive The device of FIG. 3.
- the flat fiber guide surface according to the invention can be seen particularly well 18 and the fiber delivery edge 6.
- the fiber guide surface according to the invention has a convex, concave or selected surface. This deviation the optimal shape of the flat surface is particularly recommended in cases where the staple fiber dressing has "sticky” or “slippery” fibers.
- the embodiment according to FIG. 3b with the concave fiber guide surface 18.1 is suitable especially for "slippery" fibers, which have weak, mutual adhesion exhibit.
- a convex variant of the fiber guide surface according to the invention 18.2 can be suitable for "sticky" fibers, which mutually have a stronger adhesion (the cohesion of the fibers is loosened, which means more free fiber ends can arise).
- 3d shows a wavy fiber guide surface 18.3. This can help maintain a flatter arrangement of fibers in the staple fiber structure. 3e has already been explained; it shows like the cross section B of the fiber feed channel after the redirection point (outline shown in dashed lines) larger by the hatched area is.
- Fig. 4 shows the same embodiment of the invention as Fig. 3.
- the staple fiber dressing 20 can be seen.
- the free fiber ends can at the deflection point 17 Lift 19 of the fibers in the staple fiber structure 20 (shown as an example).
- the free fiber ends 19 have both front and rear fiber ends include (corresponding to the left or right of the deflection point 17).
- These free fiber ends can do better from the vortex flow 11 are detected and placed around the inlet mouth 9. To this In this way, more free fiber ends can be spun or more wrapping fibers can be produced what improves the spinning process itself.
- 4 a shows a section I-I 4. It can be seen how the staple fiber structure 20 has a flat arrangement.
- FIG. 5 shows a further variant of the invention, in which the fiber guide surface 22 has a cylindrical trough (fiber guide surface before the deflection point 17 is flat). This trough shape of the fiber guide surface 22 leads to a concave fiber delivery edge 6.1.
- the end face 21 of the fiber delivery edge is also shown 6.1.
- FIGS. 5 a and 5 b represent sections of FIG. 5 is the in this embodiment of the invention End face 21 substantially perpendicular to the fiber delivery edge 6.1, respectively to the yarn guide channel 8.
- the end face can also have other shapes.
- FIG. 6 a shows the end face 21 may be vertical with a straight delivery edge 6.
- 6b shows a convex shape (21.1) or, as shown in FIG. 6c, one have a concave shape (21.2).
- Variants 6b and 6c are also shown in FIGS. in which the fiber delivery edge 6 and the end face 21 are not the full width of the fiber guide element Own 3c.
- the width of the fiber guide element can vary 3c taper conically in the vicinity of the fluid device 13, see above that the fiber delivery edge 6 and the end face 22.1, or 22.2, only that Have width G (compare with Fig. 6 a).
