【発明の詳細な説明】 （産業上の利用分野） 本発明は，絹紡糸様の外観及び風合を有する絹紡糸調
嵩高加工糸の製造方法に関するものである。Description: TECHNICAL FIELD The present invention relates to a method for producing a silk-spun, bulky processed yarn having a silk-spun appearance and feel.

る。(Prior Art) Conventionally, it is well known that a woven or knitted fabric using a different shrinkage mixed fiber of synthetic fiber has a silky feeling such as drapability and swelling. As a typical example of the method for producing these different shrinkage mixed fiber yarns, there is a draw mixing method. In this method, when the same undrawn yarn is drawn, the heat treatment temperature during drawing is made different, or after drawing with or without heat treatment, the ply yarn is wound.

繊度糸と単糸繊度が１デニール以下の細繊度糸を異なる
温度で延伸した後混繊し，次いで絡合処理してソフトな
風合と張り，腰を付与する方法が提案されている。Since the kneaded yarn obtained by this method has a difference in heat shrinkage depending on the difference in heat treatment temperature or the presence or absence of heat treatment, bulkiness can be obtained in the subsequent steps, and therefore many drawing and blending methods have been proposed. For example, Japanese Patent Application Laid-Open No. 63-126929 discloses that a thick fine yarn and a fine fine yarn having a single yarn fineness of 1 denier or less are drawn at different temperatures, then mixed and then entangled to give a soft feeling. A method of providing tension and waist has been proposed.

However, in recent years, it has not been possible to obtain a yarn having a peach face-like surface appearance due to the demand for fine loop fluff.

ある。しかしながら，単糸繊度が細くなればなるほど，
特に１デニール以下の極細糸になると，流体撹乱処理で
ループ毛羽を形成することが難しくなる。In order to impart a peach-face-like feel to the surface of the fabric, it is necessary to use a processed yarn in which a very fine yarn having a fineness of a single yarn is subjected to a fluid disturbance treatment to form a loop fluff. However, the finer the fineness of single yarn, the more
In particular, when the yarn is very thin, having a denier of 1 denier or less, it becomes difficult to form a loop fluff by a fluid disturbance treatment.

えられる。Usually, the fluid disturbance nozzle used in Taslan processing is
The turbulent flow of the compressed fluid gives the filaments individual opening and swirling actions to form a loop or sag on the yarn surface while bending and mixing the individual filaments intricately. However, in the Taslan processing, the effect of single yarn fineness is large, and when the single yarn fineness is 1 denier or less, the effect of opening individual filaments is poor, and therefore, the turning is performed in a state where the constituent filaments are bundled. The torque acts to form a so-called knot-like lump or a bundle-like loop due to uneven opening, making it difficult to form a loop or slack in each filament. Although the reason for this is not clear, it is considered that the physical properties (such as low Young's modulus) of the ultrafine yarn impede the opening action.

出して本発明に到達した。(Means for Solving the Problems) The present inventors have conducted intensive studies to solve the above problems, and as a result, as a means for improving the opening property of the ultrafine yarn, and as a means for stretching the fabric and imparting waist. By mixing ultra-fine yarn at a specific ratio with a thick yarn of single yarn fineness, the turbulence action of the fluid agitating nozzle allows the fine-filament filament with good openability to be completely inserted into the ultra-fine filament, making it extremely efficient. The present inventors have found that the ultrafine filament group can be divided and opened, and arrived at the present invention.

方法を要旨とするものである。That is, the present invention provides an undrawn yarn A having a single yarn fineness of 0.8 denier or less after drawing and an undrawn yarn B having a single yarn fineness of 1.5 denier or more and 3.0 denier or less after drawing. Each of the drawn yarns is drawn so that the drawing temperature of A is higher than that of the undrawn yarn B, and then the two drawn yarns are combined so that the weight ratio of the drawn yarn of A to the whole yarn is 30% or more and 60% or less. It is a gist of the present invention to provide a method for producing a silk-spun bulky processed yarn, wherein the yarn is subjected to a fluid disturbance treatment to form entanglement and loop fluff.
以下，本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail.

も欠け，商品価値が損なわれるので好ましくない。When the single yarn fineness of the drawn yarn of A exceeds 0.8 denier, even if the loop fluff is formed by the fluid disturbance treatment,
Peach face-like feel cannot be obtained. Also, if the weight ratio of the drawn yarn of A is less than 30% by weight with respect to the whole yarn, the absolute amount of the fine loop composed of extra-fine filaments becomes insufficient, and it becomes difficult to express a peach face-like feel, and the feeling becomes soft. It is not preferable because it lacks. On the other hand, if it exceeds 60%, a knot-like defect peculiar to ultrafine yarn is liable to occur due to the fluid agitation treatment, and when it is made into a woven fabric, it is not preferable because it lacks tightness and waist, and the commercial value is impaired.

The opening property of the yarn B itself is reduced, and it is not possible to promote the opening and division of the drawn yarn of the ultrafine yarn A, so that a knot or a bundle-like loop is easily generated, and furthermore, the yarn is stretched on the fabric. ， Cannot give waist. On the other hand, if the single yarn fineness of the drawn yarn of B exceeds 3.0 denier, the absolute number of filaments becomes insufficient, and similarly, it becomes impossible to promote the opening and splitting of the drawn yarn of A, which is not preferable.

こととなる。In other words, when an undrawn yarn is drawn, instantaneous shrinkage occurs immediately after drawing due to changes in the internal structure of the fiber. 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 high shrinkage yarn having a high hot water shrinkage ratio. Therefore, as in the present invention, the ultrafine undrawn yarn A is replaced with the thick fine undrawn yarn B.
When the stretching is performed at a higher heat treatment temperature, a difference occurs in the instantaneous shrinkage between the two yarns immediately after the stretching, and the stretched yarn of B having a large fineness shrinks more than the stretched yarn of A which is very fine. Moreover, a highly shrinkable yarn having a high hot water shrinkage ratio is obtained. In other words, if the stretched yarns are continuously subjected to the fluid agitation treatment under the overfeed, the above-described shrinkage characteristics operate in the fluid agitation treatment area, and the substantial overfeed between the two yarns is performed. Fluid agitation treatment is performed with slightly different rates.
The drawn yarn of B, which is a fine fineness, has a relatively core portion,
Will have a form close to the core-sheath structure in which the sheath portion is formed.
