Specifically, it relates to a composite mixed fiber yarn characterized by a mixture of three types of fibers: two types of fibers having different shrinkage and latent crimpable flat fibers made by laminating different polymers. .

ことが多く、市場化の例も数少ない。However, the above-mentioned method of spinning and blending the differently contractible Ill fibers is difficult to obtain sufficient bulk, and the above-mentioned twisting blending method causes many troubles in the spinning process and has both advantages and disadvantages. Furthermore, in the composite spinning method, there are problems with spindle unevenness in spinning and dimensional stability in sales and knitting, so it is often limited to special uses, and there are only a few examples of commercialization.

される。<Problems to be Solved by the Invention> The present invention provides a feminine fabric that has sufficient bulk, is free from spindle unevenness during spinning, and has excellent dimensional stability when woven or knitted. It is an object of the present invention to provide a bulky yarn for clothing, and also to provide a method for manufacturing the same, which does not cause troubles during spinning unlike conventional drawn and twisted mixed fiber yarns. Means for Solving the Problem> In other words, the present invention provides a fiber (■) having a seawater shrinkage ratio that is 21 or more lower than the seawater shrinkage ratio of the fiber (I), and two types of polymers. This is a mixed fiber yarn made of flat composite fibers (I) that are bonded together, and its manufacturing method involves simultaneously extruding polymers from separate nozzles in the same nozzle, spinning, and drawing. If the mixed fiber method is used, it is preferable that the two types of polymers constituting the fiber (III) are mixed.
It is characterized by a polymer constituting (I) and a polymer constituting fiber (II), and all of the above-mentioned problems can be solved by the mixed fiber yarn of the present invention and its manufacturing method.
本発明の主要点は、収縮差のある2種の混繊糸と、潜在
捲縮性を有し捲縮発現と同時に捩れ構造が発現し特殊な
光沢と嵩高性及び特殊な手触シ風合を与える複合扁平糸
を混繊し、3種のtll、維を混合するところにある。The main points of the present invention are two types of mixed fiber yarns with different shrinkage, latent crimpability, which develops a twisted structure at the same time as crimping, and has special luster, bulkiness, and special touch texture. It consists of blending composite flat yarns that give 3 types of tlls and fibers.

く、放射線方向に沿って、スリット状の孔を配列するこ
とにより容易に3穏混合糸が得られる。The present invention also provides a method for rationally producing these three types of mixed fibers at once in a spinning process using the same spinneret. As shown in Fig. 1, different polymers are placed in the center and periphery of the cap, and slit-like holes are arranged along the radial direction in order to obtain a composite flat thread at the boundary between the three. A mildly mixed yarn is obtained.

るが、工程的には複雑性が増す。Of course, it is also possible to use a method in which two types of fibers having different shrinkage rates and a flat composite spun fiber are separately spun, and then they are combined in the subsequent drawing process, false twisting process, or other process. Differences in shrinkage and physical properties can be obtained by spinning the fibers separately and combining them in a later step, but this increases the complexity of the process.
本発明による3種混繊糸から得られる効果として、主に
次の点が挙げられる。The following points are mainly mentioned as the effects obtained from the three-component yarn according to the present invention.
■ 複合扁平糸が織物に於いて捩れを生じる力は張シ合

収縮率が大なることが好ましく、収縮性の大なる側の沸
水収鄭率が少なくとも10〜20%あることが望ましく
、理想的な形として、収縮性大なるポリマー単独糸。■ The force that causes twisting of composite flat yarns in woven fabrics is due to the difference in shrinkage between the two types of polymers that are stretched together and the size of the shrinkage of the yarn, but the restraining force within the woven fabric is large. Therefore, the twist of the composite flat yarn becomes large due to the addition of fibers with high contractility or contractile force other than the composite flat yarn, bulkiness due to different contraction yarns, bulkiness due to latent crimp, and bulkiness due to twisting. There will be a triple addition of gender. From this point of view, it is preferable that the shrinkage rate of the two types of single polymer yarns other than the composite flat yarn is high, and it is desirable that the boiling water absorption rate of the side with the greater shrinkage is at least 10 to 20%, and the ideal In its form, it is a single yarn made of highly contractible polymer.

、手触シ風合が特にソフト感と腰のある特殊力風合を呈
する。■In addition to the double-to-triple bulkiness due to the combination of single-polymer blend yarn and composite flat yarn with different shrinkage rates, the presence of flat yarns that can be twisted in the yarn also makes it easier to handle. The texture is particularly soft and has a special firm feel.

、緩和する効果が本発明にあシ、扁平糸の特徴であるあ
だ光シをも減少させる。(2) As mentioned above, it is difficult to make the quality and dyeability of composite spun fibers uniform, and quality unevenness caused by the spindle opening method is particularly problematic. Furthermore, it also has the disadvantage of lacking dimensional stability when made into a woven or knitted fabric. The present invention has the effect of reducing or alleviating these drawbacks, and also reduces the bright spots that are characteristic of flat threads.

1000 m of denier, 24 filament undrawn yarn
Take-up was carried out at a speed of 7 minutes. Two of the same undrawn yarns were used to produce differentially shrinkable mixed fiber yarns using a heat treatment differential drawing method. That is, after drawing two drawn yarns with or without plate heat setting treatment at a first hot roller of 85°C, a heat treatment plate temperature of 200°C, a draw ratio of 3.55 times, and a drawing speed of 600 m/min, I took up gold thread. As a result, the boiling water shrinkage rates of both were 4.5% and 16.
It was 5%. Next, equal amounts of two types of polymers, polyethylene terephthalate/regular bright polymer and isophthalic acid 12 mole modified polyethylene terephthalate/regular bright polymer with a high intrinsic viscosity, were added.
Discharge through 2 slit holes, 96 denier, 12
Composite spinning winding of the filament flat yarn was carried out at a speed of 1000 m7 minutes. This undrawn yarn was passed through a first hot roller at 85°C, a drawing ratio of 3.25 times, and a drawing speed of 800 m.
Stretching was performed for 7 minutes. The obtained flat thread had a flatness of about 6.0 and a boiling water shrinkage rate of 19.5%. This flat thread had a conspicuous spindle pattern. The differentially contractile yarn and flat yarn obtained here were combined using an entangling nozzle at 1.8 klG and 1000 m.
The entanglement process was carried out for 7 minutes, and an entangled yarn with a number of entangled yarns of about 20 yarns/In was obtained. The resulting entangled yarn had almost no conspicuous spindle pattern.
