とする糸の加工方法である。[Prior art and its problems] Polyester is generally a crystalline polymer, and in its fiberization process, it is sufficiently heat-treated and crystallized to produce hard and strong fibers. In response to this, the present inventors previously proposed in Japanese Patent Application No. 62-279364 a method for producing polyester fibers having extremely soft texture characteristics that are completely different from conventional polyesters. That is, in the step of false-twisting two or more synthetic fiber yarns with different drawability in a aligned state, setting them during false-twisting, and then untwisting them, the setting conditions are set at room temperature or at most 120%
This yarn processing method is characterized by false twisting the yarn to a temperature of 130° C. or higher, and then heat-treating the resulting yarn at a temperature of 130° C. or higher in a subsequent step.

好適であ一つな。Surprisingly, when the yarn obtained by the above method is made into a fabric, the characteristic hardness of polyester disappears, and it has an extremely soft texture, more specifically, like marshmallow or cherry paper. It has a soft touch and is suitable for innerwear such as lingerie and baby clothing that comes into direct contact with the skin.

There is a particular thing.

。[1000 Technological Steps] In order to improve the repulsion properties of a fabric made of yarns obtained by drawing or drawing false twisting using yarns with different elongations, Measures have been taken to increase the single fiber denier of the yarn. Therefore, in order to solve the same technical problem in the present invention, we tried increasing the denier of single fibers of yarn with low elongation, but contrary to expectations, the texture of the fabric only became stiffer and No improvement in flexibility was observed.

上するという事実を究明しな。Therefore, the inventors of the present invention conducted intensive research to achieve this objective from a completely different perspective, and found that although the macroscopic appearance of yarn with high elongation appears uniform, microscopic physical properties are dispersed. We have investigated the fact that when the thread is 500 μm or less in length and has minute variations in fineness that are 10% or more thicker than the thinnest diameter part, the repulsion properties of the fabric are amazingly improved.

This "micro-induction" is achieved by thickening the single fiber denier of the yarn with high elongation to 3.5 denier or more after drawing, and mixing and entangling it with the splint yarn with low elongation, and further It has been found that this can be achieved by setting the heater temperature in the twisting process to at most 120° C. or lower to inhibit microscopic deformation of the single fiber yarn.

が提供される。Thus, according to the present invention, (1) a mixed yarn consisting of two or more types of polyester multifilament yarns having different elongations, wherein the average single fiber denier of the yarns with the greater elongation is 3.5; More than denier
The average single fiber denier of the yarn with low elongation is 3 deniers or more, and at least some constituent single fibers of the yarn with high elongation have a length of 500 μm or less, the thinnest of the yarn. A polyester blend yarn characterized in that there is a variation in fineness that is 10% or more thicker than the diameter part, and the blend yarn as a whole has 30 or more entanglements/m, and further, (2) breaking elongation. In a method in which a plurality of yarns including two polyester fiber yarns with a difference of 50% or more are aligned and subjected to a draw false twisting process, the average tensile strength after the draw false twisting is applied to yarns with a large elongation. Using an undrawn yarn with a fiber fineness of 3.5 denier or more, or an undrawn yarn with a small elongation of 3 denier or more after drawing and false twisting, and before applying the drawing and false twisting, the drawn yarn After the fibers are mixed and entangled to give a number of entanglements of 40 or more per meter, they are false-twisted and untwisted under a heater temperature of 120°C or lower, and then heat treated at a temperature of 120°C or higher. Therefore, at least a part of the constituent single fibers of the yarn with high elongation has a length of 50 mm.

There is provided a method for producing a polyester blend yarn, which is characterized by forming a variation in the fineness of the yarn.
以下、本発明を詳細に説明する。The present invention will be explained in detail below.

ある。The yarn processing method for obtaining flexible polyester filaments, which is the basic concept of the present invention, involves aligning two or more types of filament yarns with different drawability and temporarily heating them at a temperature of 120°C or less, preferably room temperature to 120°C. After twisting,
The yarn is heat treated to reduce its boiling water shrinkage rate and ensure its ease of handling. False twisting is carried out by using the yarn with the higher elongation alone, and at a stretching ratio of 120°C (near the crystallization start temperature) or less, which does not reach complete stretching.
In particular, when stretching is carried out below the glass transition point (approximately 80°C), stretching in the yarn axis direction results in uneven stretching, resulting in thick and thin yarns and causing dark and light streaks in the fabric. On the other hand, we have found that when a thread with a low elongation is attached and twisted together and stretched while twisting, the fiber can be stretched uniformly.

仮撚加工自体が難しくなる。FIG. 1 shows an example of the process for carrying out the method of the present invention, in which polyester undrawn yarn 1 has an elongation of 50
% or more, and is aligned with the undrawn polyester yarn 2 (hereinafter referred to as plating yarn) which functions as a plating yarn, and is supplied from the supply roller 3 to the false twisting processing area. After the aligned yarns 4 are intertwined with each other by an air nozzle 5, they are sent through an intermediate roller 6 to a false twister 8, where they are twisted. As a result, in front (upstream) of the false twister 8, the undrawn filament 1 is stretched by wrapping around the plating thread 2. At that time, the undrawn filament 1 forms an entanglement with the plating yarn 2 consisting of an intertwined part and a non-entangled part, and the single fiber denier of the undrawn filament 1 becomes 3.5 denier or more after drawing and false twisting. By using a thick filament and selectively setting the temperature of the heater 7 to 120°C or less, more preferably below the glass transition point (approximately 80°C), the undrawn filament 1 can be twisted and drawn as a whole filament yarn. Although the filaments are drawn uniformly by the process, the individual constituent filaments are microscopically constrained and drawn non-uniformly, leading to variations in single fiber denier among the constituent filaments, as shown in Figures 2 and 3. do. At this time, in order to make the non-uniform stretching so microscopic that it cannot be visually recognized as a dye spot, the number of entanglements given to the drawn thread 4 must be 40 or more per meter.
The larger the number, the better, and particularly preferably 60 to 120 pieces/m. The upper limit is about 150 pieces/m, and if this is exceeded, the false twisting process itself becomes difficult.

A material with a thick fineness that will not be heated uniformly when heated for 1 second or less at a temperature of 0°C or less is required, and after stretching and false twisting, the material must have a fineness of 3.5
Denier or more, preferably 4,0 denier or more, more preferably 5 denier or more is suitable. The upper limit of the thickness is about 8 denier, and if it exceeds 10 denier, it becomes too hard and difficult to false twist.

以下とすることが肝要で、好ましくはガラス転移点（略

It is important to keep the temperature below, preferably below the glass transition point (approximately 80°C), particularly preferably at room temperature.

It takes shape. The temperature required for this is 120° C. or higher, preferably 160° C. or higher, and heating may be performed for 0.1 seconds or more. In addition, to encourage variation in elongation,
A useful method is to use a contact hot plate heater to instantly shrink the fibers at the heater inlet. On the other hand, in the case of a non-contact heater, it is preferable to heat at 200° C. or higher in order to instantly shrink the fibers. The overfeed rate of the yarn to the heater 10 is suitably about -5 to +10%, but in this case, the runnability of the yarn is the best under a constant length.
