、織編物の品位を低下させるという欠点があった。(Prior Art) It is well known that woven or knitted fabrics using differentially shrinkable blended yarns of nine conventional synthetic fibers have silk-like textures such as drapability and puffiness. In addition, many filament-processed yarns have been proposed, which add spun yarn-like appearance and texture to these silk-like filament yarns. A typical example is Taslan yarn, which has been subjected to one-fluid agitation treatment.Although this yarn gives a woven or knitted fabric with a spun yarn-like appearance and feel due to the loops and slacks present on one surface, the entanglement of the loops and slacks The unwinding property from the wound package is poor, the weaving property is poor, and the quality of the woven or knitted fabric is degraded.

昭６０−９４６３６号公報には、熱水収縮率の異なる２
種の糸条を用いて芯鞘型の加工糸となし。Conventionally, as a method for solving this kind of drawback, there are two methods, for example, disclosed in Japanese Patent Application Laid-Open No. 60-94636, which have two different hot water shrinkage rates.
Core-sheath type processed yarn and pear yarn using seed yarn.

しく低下させるという欠点がある。(Problems to be Solved by the Invention) However, in this method, a fluffy and puffy feeling is imparted due to the differential shrinkage effect, and although the unwinding and weaving properties of the yarn are improved, the appearance of the fabric is impaired. There is a drawback. In other words, the core yarn and sheath yarn, which have different hot water shrinkage rates, have different shrinkage behavior during hot water contraction, so as shown in Figure 3, the core yarn and sheath yarn separate into two layers at the intertwined part. However, the sheath threads become tangled around the core thread in an undulating manner, and as a result, the appearance of the fabric appears scaly and irritated, resulting in a disadvantage that the quality of the product is significantly reduced.

調高高加工糸の製造方法を要旨とするものである。That is, in the present invention, two undrawn yarns, at least one of which is a mixed yarn of different fineness in which three or more types of single filaments with different finenesses are mixed, are drawn at different heat treatment temperatures. The gist of this invention is a method for producing highly textured silk spun yarn, which is characterized by combining yarns and subjecting them to fluid agitation treatment to form entanglement and loop fuzz.
以下９本発明の詳細な説明する。Hereinafter, nine aspects of the present invention will be described in detail.

なる。When two undrawn yarns are drawn at different heat treatment temperatures, they become two drawn yarns with different hot water shrinkage rates due to the difference in heat treatment temperature. The mixed fiber yarn is a filament with three or more types of hot water shrinkage rates due to the difference in fineness] - It is a mixed fiber yarn with different shrinkage with a mixture of groups, and by combining two drawn yarns, it has four types of hot water shrinkage rates. Preferably, the yarn is a blend of six or more types of different shrinkage fibers.

工糸を得るためには。The single fiber fineness of the undrawn yarn and the heat treatment temperature during drawing, which are factors that determine the hot water shrinkage rate of each filament constituting the differentially shrinkable mixed fiber yarn, are not particularly limited and may be selected as appropriate. In order to obtain a processed yarn that has a soft texture, tension, and waist.

延伸時の熱処理温度差を採用するのが好ましい。It is preferable to combine the single yarn fineness within a range of 0.5 to 5 d. In addition, if the difference in hot water shrinkage rate between the filament groups constituting the differentially shrinkable mixed fiber yarn is too large, the differentially shrinkable filament groups will separate during hot water treatment after being made into a fabric, resulting in scale-like irritation. Therefore, it is recommended to adopt a combination of single yarn fineness or a difference in heat treatment temperature during drawing so that the difference in hot water shrinkage rate between filament groups with the closest hot water shrinkage rate is 7% or less, especially 5% or less. is preferred.

。The overfeed rate when feeding two yarns together to the fluid treatment area may be appropriately selected according to the target loop fuzz of the resulting intertwined yarn. The content is preferably 3 to 20% in order to keep the unwinding property within a range that does not impair the unraveling property and to impart fluffiness and fullness that are lacking in the yarn stage through heat treatment after fabrication.

る。したがって１本発明のごと（。In other words, 9 Normally, when undrawn yarn is drawn, instantaneous shrinkage occurs immediately after drawing due to changes in the internal structure of the fiber, but the amount of shrinkage varies depending on the heat treatment temperature during drawing, and the lower the heat treatment temperature, the greater the amount of shrinkage immediately after drawing. In addition, the yarn itself becomes a highly shrinkable yarn with a high hot water shrinkage rate. Furthermore, if the undrawn yarn is a mixed yarn of different fineness, the heat receiving effect between filaments of different fineness is slightly different, so the amount of shrinkage between filaments of different fineness will also be different, and filaments of large fineness will shrink more than filaments of fineness. The amount is large, and the hot water shrinkage rate is also high. Therefore, as per the present invention (.

ため、比較的低温側の糸条が芯部を、高温側の糸条が鞘
部を構成した芯鞘構造に近い形態を呈することとなる。When two undrawn yarns, at least one of which is composed of three or more mixed yarns of different finenesses, are stretched at different heat treatment temperatures, there is a difference in the amount of instantaneous shrinkage between the two yarns immediately after stretching. As a result, the low-temperature side yarn shrinks more than the high-temperature side yarn, and becomes a high-shrinkage yarn with a high hot water shrinkage rate. Furthermore, subtle changes in the amount of shrinkage occur between the low-temperature side yarn and the high-temperature side yarn due to the difference in fineness. In other words, if both drawn yarns are continuously subjected to fluid agitation treatment under overfeed, the above-mentioned shrinkage characteristics will act in the fluid treatment area.
Since the fluid agitation process is performed with the actual overfeed rate between both yarns and filaments slightly different, the yarn on the relatively low temperature side serves as the core, and the yarn on the high temperature side serves as the sheath. It has a form similar to that of a core-sheath structure.
したがって。therefore.

As shown in b), the loop shape on the yarn surface changes in a complex manner, and many fine voids are formed between the filaments.
Due to the complex intertwining of filaments and the differential shrinkage mixed fiber effect, it is possible to suppress the separation of fibers or the formation of wavy waves in the entire yarn. For this reason, (1) the fabric obtained from the bulky yarn according to the present invention is free from irritation, and also has improved fluffiness and fluffiness due to the complex changes in the loop shape on the yarn surface and the large number of fine voids formed between the filaments. be able to.
