である。[Detailed description of the invention] The present invention is based on the difference in elongation after crimping by false twisting by simultaneously supplying two yarns of polyester multi-filament yarn with different elongations at break. The present invention relates to a method of producing knotted yarn by utilizing the difference in processed yarn length to locally concentrate yarns with high elongation after processing by squeezing together with other yarns.

るものである。 Multi-filament yarn of polyester synthetic fiber is usually made from undrawn yarn obtained by melt spinning.
Stretched 2.5 to 4.5 times to give appropriate strength and elongation,
Subject to crimping. The crimped yarn thus obtained is bulky and has good crimpability, but the coldness of synthetic fibers and the flatness of the surface of the fabric are inferior to those of natural fibers. The present invention aims to eliminate such drawbacks and to obtain an appearance and texture similar to spun yarn by locally forming slabs or neps in the yarn.

ある。 In other words, the gist of the present invention is to align undrawn yarns of polyester synthetic fibers or yarns with a large elongation at break such as semi-drawn yarns with ordinary drawn yarns or to twist them together and false twist them. The processed yarn length resulting from the false twisting process is obtained by simultaneously supplying the yarn to the device in parallel and crimping with an overfeed similar to the case of drawn yarn, and then applying ironing to both yarns with appropriate guides. This method is characterized by locally concentrating the differences between the two groups, and then using fluid treatment to intertwine filament groups that form locally concentrated nodular masses.

明した。 Undrawn yarn or semi-drawn yarn usually has a drawn yarn of 15~
It typically has a much higher elongation at break of 50-250%, whereas it has an elongation at break of 35%.
If both yarns exhibiting such a large difference in elongation are twisted or pulled together and fed to a false twisting machine at the same time, they may be heated during twisting in the false twisting process, resulting in normal stretching with a small elongation. Overfeed when false twisting yarn [(Feed roller surface speed - Delivery roller surface speed) / Feed roller surface speed x
100%] to the twisting area, the stress on the yarn due to the twisting operation is naturally high for yarns with low elongation, but low for yarns with high elongation; Because of its low properties, it is easily plasticized, and the threads are easily stretched by twisting. For example, elongation at break 25
% drawn yarn and undrawn yarn with break elongation of 235% were aligned and subjected to false twisting at 205℃, and the yarn difference was measured. It was found that the undrawn yarn had a 21.3% longer yarn length. did.

た節部１４とによつて特殊節糸を構成する。 The present invention utilizes such a phenomenon to concentrate the yarn length differences of processed yarns to create knotted yarns. 2 shows a normal drawn polyester yarn and Yarn 2 shows a semi-drawn yarn. Both yarns are pulled together and fed simultaneously from the feed roller 3, and passed through a false twisting process consisting of the feed roller 3, heater 4, false twist spindle 5, and delivery roller 6, which includes twisting, heat setting, and untwisting operations. From the above phenomenon, yarns with a large elongation at break have a processed yarn length of at least 10% compared to yarns with a small elongation.
It becomes longer and is sent out from the delivery roller 6. As described above, even though the yarn length is the same during feeding, the processed yarns with different yarn lengths when being fed out are then introduced into a slight stretching area constituted by the delivery roller 6 and the feed roller 8, and then guided by the guide 7. The long threads are forced along the short threads or locally concentrated around the short threads to form knots. The form of such knots can be varied depending on the elongation at break, the properties of the supplied yarn, the number of constituent filaments, the thickness, the elongation, and the difference in length of processed yarn. Subsequently, the first feed roller 8 and the second feed roller 1
The filament bundles forming the joints are entangled and fixed by introducing the filament into a slight relaxation region consisting of 0 and passing through a fluid agitation nozzle 9 installed in the same region. After undergoing such intertwining action, both threads are integrated into one
It becomes a new thread of the book and is rolled up by the winding roller 11.
It is rolled up as shown in 2. FIG. 2 shows the appearance of the yarn obtained in this way, and it is simply a special knotted yarn formed by a point 13 where two yarns are intertwined and a knot 14 formed by a yarn with a high breaking elongation. Configure.

The surface speed of the roller 8 was changed so that the tension of the yarn after passing through the guide 7 was 50 g, and ironing was applied. The knotted yarn thus obtained is then passed through a fluid agitation nozzle installed between the rollers 8, 10 by reducing the speed of the roller 10 by 7% in the direction of relaxing the surface speed of the rollers 8, 10 to provide entanglement with the fluid. The yarns were intertwined to form a single yarn. The obtained processed yarn became a knotted yarn as shown in FIG. 2, and when the processed yarn was inserted into a weft to form a woven fabric, it had a sleeve-like appearance.
