法における改良に関する。Detailed Description of the Invention The present invention is a composite processing method in which filament yarns with different elongations are subjected to simultaneous stretching, false twisting, and longitudinal processing in a twilled and intertwined state to create a two-layer structure with a spun-like texture. Concerning improvements in composite processing methods for obtaining yarn.

やすい為、糸条の外層部をとりまくように撚糸される。Conventionally, alternately twisted two-layer structured yarns using false twisting have been manufactured by the method described below. In general, when two or more types of yarns with different elongations are supplied to the supply roller in a lined state and burned by a temporary combustion spindle, the yarns with lower elongations are difficult to elongate, so they form the core of the yarn. Since yarns with high elongation are easy to stretch, they are twisted so as to surround the outer layer of the yarn.

(Refer to Japanese Unexamined Patent Application Publication No. 49-72443 and Japanese Patent Publication No. 49-47644.) On the other hand, as another method for producing double-structured yarn having the above-mentioned form, the yarn is twisted into a twisted (false-twisted) state using a false-twisting spindle. It is also well known to use the rotational torque of a certain core yarn to overfeed a winding yarn while winding it.

付糸は交互撚糸状に芯糸の周りに捲付いていることから
、その撚糸効果によりスパンラィクな風合を呈するもの
と言われている。(For example, see Tsubaki Kosho No. 45-28018.) In the two-layer structure yarn obtained by these methods, the wound yarn is generally wound around the core yarn in an alternately twisted manner, so the twisting effect makes it spun-like. It is said to have a unique texture.

ちらかというと硬い風合と低い嵩高性をかもし出し、ス
パンラィク風合としては不充分なものであった。In each twisted yarn area (S or Z winding section), there are usually at least three twists, and this produces the above-mentioned twisting effect. By the way, the false twisted yarn having such a yarn structure has the advantage of improving the sliminess and fluffiness that are the drawbacks of ordinary woolly textured yarn fabrics due to its twisted yarn structure. Because the threads were wound tightly, the lacquered thread structure produced a rather hard texture and low bulk, which was insufficient for a spun-like texture.

た。In addition, in this type of processed yarn, when the yarn is squeezed by a yarn guide etc. during the false twisting process or the weaving process, the ported yarn slips between the core yarn and generates neps, which causes the yarn to become loose during the process. There was a problem that this resulted in an increase in breakage and a decrease in the quality of the fabric. The inventors,
The above-mentioned drawbacks of the conventional alternately twisted two-layer structure yarn have been improved, and the yarn has an appropriate twist texture and bulge, and is free from the concern that the wound yarn may slip and cause naps due to external forces such as squeezing. No permanently stabilized bilayer yarns were provided.

には“虫喰い”と呼ばれる梁欠点が生じ、製品の実用的
価値が全く損われることが判明した。One of the features of this yarn is that while the yarn burnout effect is reduced compared to a complete burnout (winding), it is possible to obtain an extremely short pitch, that is, a state in which the wound yarns alternately cross in opposite directions with respect to the yarn axis, so it is moderate. The twisted yarn effect is maintained, and the winding condition is looser than when completely twisted, and since the wound yarn as a whole is reversed, a spun-like texture (bulge feeling and soft touch) is also created. This can be mentioned. However, it has been found that when the above-mentioned yarn is knitted and dyed, a beam defect called "tiger step" or even "bug-eaten" sometimes occurs, completely impairing the practical value of the product.

態で捲付いている未解撚部分であることを知った。Here, "tiger dan" refers to the darkly dyed streaks in the weft direction of the knitted fabric, and "bug bite" refers to the more transparent spots on the knitted fabric. As a result of pursuing the cause of the above phenomenon, the inventors of the present invention found that in Toradan, the winding thread does not actually wind around the core thread, and that the winding thread does not actually wind around the core thread in this part of the tiger stage. I learned that the length ranges from the 1st term danga to more than 1w, and that the insect bite is the untwisted part where the winding thread is wound on several sides in a continuous state in one direction. .

点を有しているからである。This can be seen in the specification of the earlier application (Japanese Patent Application No. 53-7154).
This has been mentioned before, but I'll mention it again here. In the production of the above-mentioned false-twisted double-layer structure yarn, a low speed of 100 skins/mjn or less has generally been adopted, but especially when trying to obtain a high quality product as a woven or knitted fabric, a uniform A processed yarn with a winding structure is required, and for this reason, 60′
Carefully manufactured at low speeds below min. Therefore,
The problem was that productivity was poor and commercially unprofitable. The reason why such a low speed has to be adopted is that the yarn structure is unique in that it is an alternately twisted yarn, which has the disadvantage that the yarn structure stability is extremely poor during the false twisting (crimping) process and the weaving process. It is from.

捲付構造の二層構造糸を加工速度への依存性なく得るこ
とにある。In particular, in temporary lacquer processing, the thread structure changes so sensitively that it is unimaginable with ordinary woolly processed regular weaves.
At processing speeds below 0 machine'min, core yarn 1 is
A uniform two-layer structure in which the winding threads 2 are alternately twisted around the A layered structure is obtained, but at 150 to 250 m'min, the fixed structure as shown in Fig. 7 is only partially formed, and further
If the speed exceeds 0m/min, a wrapped structure will no longer be obtained.
As shown in FIG. 8, only the wound yarn is obtained which is completely separated into two yarns. Therefore, the purpose of the present invention is to eliminate the above-mentioned drawback that the winding structure depends on the processing speed at a processing speed of 100 min or more, and to process a double-layered yarn with a uniform winding structure. The goal is to obtain speed independent.

(K value), and arrived at the present invention.

加工法が提供される。Thus, according to the present invention, at least two types of filament yarns having a difference in elongation of 100% or more are mixed and intertwined and frictionally false-twisted at a processing speed of 100/mjn or more under underfeed. When obtaining an alternately twisted thread-like wound structure yarn by subjecting it to shrinkage processing,
A composite processing method is provided, which is characterized in that the K value [untwisting tension (twisting force)/twisting tension (twisting force)] during the processing is maintained in a range of 0.5 to 1.0.

うに条件が選ばれる。An embodiment for obtaining a two-layer structured yarn of the present invention will be described with reference to FIG. 5, it is supplied to an air injection nozzle 6 for mixing and entangling, where it is made into an entangled yarn having 20 or more interlacing points. Next, this intertwined yarn is supplied to a drawing false twisting zone by a first delivery roller 7, passes through a heater 8 and a false twisting odor 9, is taken off from a second delivery roller 1, and is then wound up as cheese 11. At this time, conditions are selected so that the K value [untwisting tension L: 2/twisting tension T,: 2] is 0.5 to 1.0.

A range in which the K value is 0.5 to 1.0 is selected depending on the running angle of the yarn (8 in FIG. 3) such as r/Vy. FIG. 4 shows the relationship between the K value and the running angle of the yarn when Vr/Vy is variously changed using the triaxial circumscribed friction false twister used in Example 1, which will be described later. A K value of 5 to 1.0 is V
If either r/Vy or a is set, the other can be easily selected.

In the present invention, since a friction false twisting disk is used in the present invention, slipping is likely to occur between the yarn being burned and the disk, and this may destroy the alternating winding structure formed during scale burning. There are also concerns that

いては以下の如く説明される。Generally, the above-mentioned problem is basically solved because two yarns that have been pre-interlaced are used. However, in reality, there may be areas where there is no entanglement or areas where the entanglement effect is weak due to uneven entanglement applied to the raw yarn.
Similar problems may occur, albeit to a lesser extent. The best way to prevent this problem of yarn structure destruction is to reduce the centrifugal force that acts on the yarn under special conditions, that is, at the untwisting point where the structure of the processed yarn is determined. Specifically, the aim is to reduce the radius of rotation of the yarn at the untwisting point, and to make the ballooning amplitude minute. This can be done by reducing the ballooning by using a yarn guiding guide or the like, but the guide near the untwisting section installed in a general false twisting machine is not useful. In particular, ballooning at high speeds becomes extremely large because the force is proportional to the rotational angular velocity, and in order to stop the ballooning, it is necessary to It is necessary to provide guides etc. extremely close to each other in the range of 2 to 2 sides. The formation of the two-layered yarn described above will be explained as follows.

伸長できる糸条を用いる。However, fishing fibers made of filaments with different elongation
When the intertwined yarns are burned in the same way, the stress balance between the low elongation filaments and the high elongation filaments is disrupted with respect to the tensile stress generated in the yarns. However, in this case, most of the high elongation filaments are stretched more than the low elongation filaments and are wrapped around the latter to maintain stress balance as a single thread. I come to keep it. As a result, by creating a difference in elongation between the filaments even if the constituent filaments are in a mixed or interwoven state, the group of high elongation filaments is combined with the group of low elongation filaments in false twisting. A two-layered yarn is formed that is wound in the same direction. Furthermore, the two-layered yarn is heated with a heater to cause plastic deformation of the transverse filaments and fixed in that state, and then scaled and burned to form a core made of low elongation filaments and a sheath made of high elongation filaments. An alternately wound structural yarn is formed. At first glance, it may seem difficult to transition to a two-layer structure with blended and interlaced yarns, but we use yarns with different elongations, and process them with a K value of 0.5. A uniform two-layer structure can be smoothly formed by processing under underfeed, which applies a higher tensile stress, using a friction false twisting device that can be set in the range of ~1.0. As for the combination of two or more types of filaments in the present invention, the yarn with lower elongation is a yarn that can be false-twisted at least under underfeed, and the yarn with higher elongation is further 100% Use yarn that can be stretched by more than %.

Use a combination with undrawn yarn exceeding . Further, in the present invention, the term "filament yarn" refers primarily to polyethylene terephthalate, but it may also be one copolymerized with a third component at a proportion of 15 mol% or less.

用できる。Further, the polyester may contain additives such as a matting agent, a coloring agent, and a flame retardant. Further, although the undrawn yarn and the oriented yarn may have the same filament cross-sectional shape, content of matting agent, presence or absence of colorant, etc., at least any of these may be made different. In this case, the denier of the undrawn yarn and the partially oriented yarn should be selected depending on the application, but generally, in the total denier, the wrapped yarn denier/core yarn denier ZO. 7, the former is preferably 50 to 30 Me, and the latter is preferably 50 to 30 Me. In addition, considering the draw ratio during processing, the single fiber denier should be a combination in which the total single fiber denier after processing is speared yarn ≦ the core yarn, and the single fiber total denier of the wound yarn after processing is less than or equal to paper e. It is particularly preferable that the total single fiber denier of the core yarn is equal to or greater than masu e. By combining the yarns as described above, it is possible to obtain a woven or knitted fabric having bulkiness, a soft surface feel, and elasticity/resistance.
Further, as the air injection nozzle, a generally used nozzle for interlace processing is suitable, and a Taslan nozzle can also be applied.

The intertwined part and the open weave part form a repeating unit to constitute the interlaced yarn, but in order to optimally carry out the present invention, the interlacing is provided such that the length of the intertwined part is long and the length of the open weave part is short. It's good. Further, the number of entanglements is 2M or more per meter, preferably 30 or more per machine, from the viewpoint of improving high-speed processability and ease of handling in post-processes. Note that the degree of entanglement is measured as follows.

As described above, according to the present invention, an improved alternately twisted two-layer structure yarn that can provide a spun-like woven or knitted fabric having appropriate twist texture, swelling, and flexibility can be obtained.

。Here, as the false twisting device, a circumferential friction false twisting device of the same type as in Example 1 was used, and L was changed to adjust 8. The processed yarns obtained in each experiment were evaluated after knitting and dyeing in the same manner as in Example 1, and the results are shown in Table 2. Table 2 *: As is clear from the results of Tables 1 and 2 for the comparative examples, the K value is 0.
In the range of less than 5, insect bite occurs frequently and the texture is rough, making it impossible to put it to practical use as a spunlike woven or knitted fabric.
