Definitions
- the invention relates to a method for pre-interlacing an undrawn or partially drawn (LOY, MOY, POY, FOY) synthetic multifilament original yarn for the drawing, texturing and / or drawing texturing process for the production of a textured yarn or plain yarn for textile fabrics and after Processed yarn.
- LOY undrawn or partially drawn
- a swirling process is known, according to which an undrawn or partially stretched original yarn, for a false twist texturing process, is swirled weakly at an air pressure of approximately 0.5 bar in order not to weaken the actual texturing process due to excessive swirling points in the form of knots disturb.
- the knots created in the master yarn must dissolve again during the further processing of the yarns in order to avoid defects.
- the object of the known method is to reduce thread breaks, particularly in the case of fine-fibrillated yarns. After texturing, these are yarns then swirl again, the thread closure of the textured yarn produced here having the same task as for the original yarn, namely the improvement or the guarantee of further processability.
- the swirling points according to the known method have the disadvantage that they disrupt the uniformity of the product image, especially in the case of fine titers. So far, it has not been possible to weave sufficiently interwoven textured yarns for a smooth bobbin run-off without giving up an uneasy product appearance.
- the object of the invention is to provide a method which ensures good thread closure in a textured or stretched filament yarn, ensures problem-free bobbin flow during further processing, and enables a fabric which is as free of drawing as possible.
- the invention serving to achieve the object is characterized in that the intermingling takes place at an air pressure of 0.5 to 3.0 bar before the entry yarn enters the drawing, texturing and / or drawing texturing zone.
- the intermingling takes place before the yarn enters the texturing devices at an air pressure in the nozzle body of approximately 0.5 to 3.0 bar, in particular of 1.0 to 2.5 bar and preferably of 1.5 to 2.0 bar.
- the pre-interlaced yarn which is both a textured yarn and a plain yarn can have a "continuously" swirling characteristic.
- continuous interlacing is used to document a type of interlacing that has no pronounced interlacing points, in contrast to the known interlacing, for which clearly visible nodes are characteristic at periodic intervals.
- the number of fluff also reaches a minimum of around 80 fluff per 100,000 m yarn length and provides a drawing-free product image in a fabric.
- Fluff means broken filaments and / or thread elements protruding from the thread core.
- the fluff was measured using a TORAY measuring head, which works on the electro-optical principle.
- the test speed was 1000 m / min, the tested yarn length per variant 1.6 x 10 5 m.
- a polyester POY with a titer of nominally dtex 100 f 72 was used as the feed thread.
- Closed 2-hole nozzles for example with an air duct diameter of 0.7 mm, are best suited as interlacing nozzles.
- other commercially available swirling nozzles can also be used, which ensure a constant pressure in the stressed area.
- the texturing was carried out at 500 m / min on an FK6-CF texturing machine from BARMAG AG.
- the intermingling increases continuously to 65 knots / m at an air pressure of 2.5 bar.
- the number of knots is far below that of a yarn which is normally intermingled at 2.5 bar, without the bobbin winding deteriorating.
- the swirling takes place in a known manner after the texturing before the winding.
- a polyester POY with a titer of nominally dtex 167 f 36 octolobal was used as the original yarn by the method according to the invention.
- the test results are summarized in Table 2. The same tendencies can be seen in the bobbin winding behavior, the number of knots and the fabric image.
- FIG. 1 shows a comparison of the measurement results of the intermingling according to the invention with the prior art
- FIG. 2 shows a product image with a non-intermingled thread
- FIG. 3 shows the product image with the pre-intermingling according to the invention at 2.5 bar air pressure
- FIG. 4 swirls the product image normally 2.5 bar air pressure
- FIG. 5 shows a variant of the measurement results with a different titer than FIG. 1.
- Fig. 1 the essential difference between a non-swirled yarn 1, a yarn 2 swirled according to the invention at 2.5 bar and a yarn 3 normally swirled at 2.5 bar is shown using the measurement recordings of a yarn thickness measuring device. The measurements were carried out using a swirl measuring device type KMG-4 from VISCOSUISSE SA. The product image of an unwired thread obtained according to FIG. 2 is free of drawings. However, a very bad bobbin sequence during weft insertion (weaving) because of the frequent thread breaks makes the processing of such a yarn uneconomical.
- FIG 3 shows the product image after the preliminary swirling according to the invention at 2.5 bar. Slight intermingling knots are still visible here, but the loss of goods can be described as good.
- the measurement chart of the yarn thickness measurement nominally shows the typical difference between the two types of intermingling with the titer of dtex 167 f 36.
- Curve 4 shows the vortexing according to the invention; curve 5 is a normally intermingled yarn.
- the textured yarn produced by the method according to the invention results in a perfect fabric appearance, since obviously only a sufficient dissolution of the applied swirling points occurs during the texturing process that the remaining swirling comes close to a so-called "continuous" swirling.
- An advantage of the quasi-continuous interlacing is above all the low drawing in the fabric with at the same time sufficient thread closure for a perfect processing.
