The present invention relates to a method for manufacturing a composite textured yarn consisting of a crimped yarn and a non-crimped yarn. More specifically, it relates to a method for producing a slightly crimpable composite textured yarn consisting of a false twisted crimped yarn that has low crimpability and strong torque and a multifilament yarn that has virtually no crimpability or torque. It is. BACKGROUND ART Conventionally, methods have been proposed for producing bulky composite textured yarns or mixed fiber yarns by subjecting crimped yarns and non-crimped yarns to fluid treatment. However, most of them are aimed at making the filament yarn spunlike, and aim to obtain a bulkier textured yarn. For example, crimpable loop yarn (Special Publication 38-196-
No. 15313), a core-sheath type composite yarn in which non-crimped filament yarn is supplied in excess of crimped yarn (Japanese Patent Application Laid-open No. 1531-
49948, Japanese Patent Application Laid-open No. 52-42955), and a method for producing a mixed yarn consisting of crimped yarn and non-crimped yarn with extremely high heat shrinkage rate (Japanese Patent Laid-Open No. 54-64153). . In addition, Tokkosho, which utilizes the torque characteristics of false twisted crimped yarn,
Publication No. 47-23349 discloses a yarn with high torque properties obtained by false twisting with a low number of false twists and a twisted loop created by relaxing a yarn with low crimping, and a yarn with low elasticity. A method for manufacturing a loop yarn in which the yarns are aligned and twisted is disclosed. As mentioned above, these conventional techniques are aimed at improving volume and bulkiness. For this reason, consideration has been given to creating a large number of loops or slack in the yarn, or giving excessive yarn length differences or heat shrinkage differences. As a result,
Practical drawbacks have been pointed out, such as poor unwinding of the yarn, deterioration of yarn quality due to displacement of yarn layers, and poor process passability in the twisting process or the weaving and weaving process. Also, those that use a twisting machine to bundle the threads by twisting, turning, etc. (for example, Japanese Patent Publication No. 47-23349)
It also has drawbacks such as slow processing speed and low productivity, resulting in high costs. The present invention eliminates the drawbacks of the conventional yarn, and is completely different from the conventional technology in that it gives the yarn a moderate soft bulge, excellent drapability, and weight, giving it a silk-like appearance. The object of the present invention is to provide a method for producing a composite processed yarn suitable for obtaining a knitted fabric with an elegant appearance and texture. That is, the present invention provides a false-twisted crimped yarn with low crimpability and strong torque, which is obtained by false-twisting and crimping a thermoplastic synthetic fiber multifilament yarn with a false twist count of 80% or less of the normal false twist count. The object of the present invention can be achieved by a configuration in which multifilament yarns having substantially no crimp or torque are combined and subjected to interlacing treatment. The normal false twist number here is a value close to the limit point of double twist generation, is used in general false twist processing, and means the false twist number (T) expressed by the following formula. . (T: false twist number (T/M), D: denier,
α = 1 to 1.3) In addition, the entanglement process refers to the process of injecting fluid through one or more fluid introduction holes in a direction perpendicular to the axis of the yarn running in the thread path or at an appropriate angle. It means to intersect or intertwine the individual single filaments that make up the yarn by injecting it or by applying a fluid approximately perpendicularly to the yarn at the fluid outlet of a nozzle. In the present invention, the most preferable aspect is that no loops are generated in the yarn by the interlacing treatment, and it is desirable that there are almost no loops of the Cournode type.
There is no problem even if the arched loop is slightly raised. Next, the features and effects of the present invention will be described. The composite processed yarn obtained by the method of the present invention is
It has a moderately soft bulge, does not feel loose or fluffy, and exhibits an extremely desirable texture with excellent drapability. Furthermore, since the yarn has excellent shape retention and yarn unwinding properties, the yarn is easy to handle in subsequent processes such as twisting, weaving, knitting and weaving. Next, these effects will be explained in detail in relation to the above configuration. (1) The method of the present invention skillfully utilizes the strong torque and low crimp characteristics of low crimp false twisted yarn that has been false twisted with a low number of false twists. It is well known that when such low-crimp false twisted yarn is relaxed, many twisted loops are generated, and the processed yarn that is bundled together with other yarns after generating the twisted loops is bulky. It is already known as a spunlike yarn with excellent properties. As mentioned above, the present invention is completely different in its orientation from these known techniques. In other words, the present invention efficiently suppresses bulkiness and volume by intertwining the yarn with other filaments without creating twisted loops, and the low-crimp false twisted yarn is essentially Taking advantage of the characteristics that each single yarn easily separates when relaxed and that many twisted snarls occur in each single yarn, the bundle properties are complexly and subtly changed in the longitudinal direction of the yarn, and the yarn is unique to filament yarn. This reduces the slimy feeling of the fabric and improves drape properties. Specifically, such a false-twisted crimped yarn is obtained by false-twisting and crimp processing with the number of false twists being 80% or less of the normal number of false twists. In this case, if the number of false twists is higher than this, not only will the torque characteristics be reduced, but also the crimpability will be increased, so that the yarn after the interlacing treatment will have increased bulk and volume, giving it a spun-like texture. is too emphasized and a desirable texture cannot be obtained. In addition, in the case of a low-elasticity crimped yarn whose crimpability has been reduced by reheating after false twisting, the torque characteristics are reduced or eliminated by the reheating. Therefore, after the interlacing treatment, the yarn cannot have a complex convergence property in the longitudinal direction, resulting in a smooth and monotonous appearance.
This results in undesirable results. Furthermore, the low crimp false twisting process with a low number of false twists in the method of the present invention can also enhance the effect of the interlacing treatment described below. The present inventor supplied various processed yarns with different false twisting conditions and investigated the entangling properties. According to the results, the entangling effect increases as the crimpability of the processed yarn decreases, and the Very good effects were obtained when the number was lowered. As detailed above, in the present invention, it is essential that the false-twisted crimped yarn be false-twisted and crimped at a false-twist number that is 20% or more lower than the normal false-twist number. (2) Next, the present invention combines the low crimpability and strong torque false twisted yarn described above with a non-crimpable multifilament yarn that has virtually no torque, and performs an interlacing process. Therefore, it is possible to efficiently suppress the feeling of looseness and fluffiness of the fabric product, and to enhance the effect of improving drapability. In this case, the above effect can be further improved by minimizing the difference in heat shrinkage and yarn length between the low-crimp yarn and the non-crimp yarn. Especially when the heat shrinkage rate of non-crimped yarn is extremely high compared to low-crimped yarn,
Another drawback is that the fabric product is prone to wrinkles. In the present invention, extremely excellent effects can be achieved when the difference in hot water shrinkage rate is 10% or less. Note that the hot water shrinkage rate is measured in accordance with the filament shrinkage rate test regulations of JIS standard L-1090-1970. The present invention can also enhance the entanglement treatment effect by using non-twisted or slightly twisted non-crimped yarns that have substantially no torque. As long as the non-crimped yarn is a multifilament yarn, various fibers such as thermoplastic synthetic fibers, recycled fibers, and semi-synthetic fibers can be used. Furthermore, in the most preferred embodiment of the present invention, the low-crimped false twisted yarn and the non-crimped filament yarn are both fed to the entangling treatment zone by the same roller, but each yarn is fed from two rollers. There is no problem in supplying them separately to the entanglement processing zone. In this case, a difference in supply may be intentionally provided for the purpose of improving entangling properties, but as the difference in supply increases, the bulkiness and volume increase, making it impossible to obtain drapability. In addition, slack occurs in the yarn, which reduces the unwinding ability of the yarn.
It is important to take these factors into consideration and select the supply difference appropriately, as this may cause defects such as displacement of yarn layers due to twisting or straining that occurs during the weaving and weaving process. (3) The present invention provides loops in the yarn through interlacing treatment.
Avoid sagging as much as possible,
It intertwines individual single filaments and increases the morphological stability of the yarn. In this fluid treatment, there is no problem if there are some arch-shaped loops, but if a large number of arch-shaped loops or croon-shaped loops occur in the yarn, bulkiness and volume will be emphasized. This results in disadvantages such as not having a desirable texture such as a stiff or Hershey feel, and also having poor yarn unwinding properties. For this reason, the entanglement treatment device uses a so-called taslan type nozzle, which applies fluid almost perpendicularly to the yarn at the fluid outlet of the nozzle, and uses a low overfeed rate, low pressure, etc. to prevent the formation of many loops. Alternatively, the fluid may be jetted from one or more fluid introduction holes perpendicular to or at an appropriate angle to the axis of the thread running through the thread path. It is preferable to use such a nozzle, a so-called commonly used interlaced nozzle. By performing the entangling process continuously after the false twisting process, the entangling effect is further enhanced and processing can be performed at low pressure, low flow rate, and high speed. Next, a more detailed explanation will be given with reference to examples. Example 1 Round cross-section bright yarn Y 1 of polyester multifilament 50d/24f was prepared using the apparatus shown in Fig . 1.
The number of false twists is 2700 Z by feeding from feed roller 1.
While false twisting and crimp processing is performed by spindle 3 under the conditions of T/M, overfeed rate 3%, and heater 2 temperature of 200°C, polyester multifilament 75d/72f round section brightening is carried out before the first delivery roller 4. The threads Y 2 are merged and supplied from the first delivery roller 4 to the fluid treatment zone (between the first delivery roller 4 and the second delivery roller 6), as disclosed in Japanese Patent Publication No. 37-1175, etc. Using the fluid treatment nozzle 5 shown in the figure, the fluid pressure is 3Kg/cm 2 and the overfeed rate is 2%.
After being subjected to fluid entanglement treatment, it was passed through a second delivery roller 6 and rolled into cheese 7. The obtained composite textured yarn had almost no loops or slack, and had 70 to 80 entangled parts/m.
The hot water shrinkage rate of the polyesters 75d/72f used was 8%, and the hot water shrinkage rate of the polyesters 50d/24f after false twisting was 6.2%. When the thus obtained composite processed yarn was made into a knitted fabric and dyed and finished, the fabric obtained had appropriate flexibility and fullness due to the slight difference in heat shrinkage, and had an extremely excellent drape. exhibited gender. Example 2 Using the same equipment as in Example 1, nylon multifilament 75d/24f, triangular cross section, bright yarn was false twisted at 1800 S T/M, overfeed rate 1%, heater temperature 180°C. After false twisting and crimp processing, nylon multifilament 75d/
36f triangular cross-section bright yarns (hot water shrinkage rate 13%) were merged and subjected to fluid entanglement treatment at a fluid pressure of 3 Kg/cm 2 and an overfeed rate of 2%. The hot water shrinkage rate of the false twisted yarn was 6.5%. The thus obtained composite processed yarn was additionally twisted at 1500T/M each in S and Z, and the additionally twisted yarns were arranged alternately in S and Z to produce a textured fabric and obtain a product with extremely excellent drapability. . Example 3 Polyester multifilament 75d/24f triangular cross section for false twisted crimped yarn, bright yarn, polyester multifilament for non-crimped yarn
75d/48f triangular cross section, bright yarn (hot water shrinkage rate 15
%) using a method similar to Example 1,
A composite textured yarn of the present invention was obtained by sequentially performing false twisting and fluid entangling under the following conditions. In addition, when the false twisted yarn was sampled and the hot water shrinkage rate was measured, it was 5.8%.

A so-called silk-spun product with a natural appearance due to subtle changes in focusing properties or slight differences in shrinkage was obtained.
