2. Description of the Related Art Conventionally, various efforts have been made to bring a polyester filament close to the texture of silk. As a method of giving a soft and swelling feeling, a method of fluid-entanglement-mixing a plurality of yarns having different contraction rates is well known, but these are restrained by wefts and warps in the fabric to give a sufficient swelling feeling. Not up to now. Further, in order to give a soft feeling, some contrivances such as making a part of a plurality of yarns finer denier have been made, but there is a limit in the yarn making technology. Also,
In order to give a soft feeling, a method of elution and thinning the yarn by alkali weight reduction processing is generally known and used as an effective means. However, there has been a problem in that a product subjected to alkali weight reduction in order to provide a suitable soft feeling lacks in a significantly tight feeling and a desired fabric cannot be obtained. A polyester blended yarn which gives a fabric having an excellent swelling feeling and a soft touch and also having a better tension and elasticity has not been obtained yet.

Can be manufactured. Further, the filament B may be a so-called spin-draw yarn in which a polyester polymer is melt-spun and subsequently drawn through a drawing device and then wound, or a yarn in which an undrawn yarn is taken up by spinning and drawn by a twisting machine. Then, in order to make the alkali weight loss rate of the filament A 1.4 times or more the alkali weight loss rate of the filament B, from the filaments obtained by the above production method, for example, at 5000 m / min or more after melt spinning. This can be achieved by combining the directly wound yarn as a filament A, and the melt-spun and subsequently stretched and wound yarn as a filament B through a stretching device.

Next, in the mixed yarn of the present invention, the number of interlaced parts must be 20 / m or more, preferably 35 / m or more. If it is less than this range, the filament A and the filament B are not preferable because they may cause skin troubles during handling such as weaving and may cause troubles or stains after dyeing. Further, the denier composition ratio of the filament A in the mixed yarn should be 30 to 70%, preferably 35 to 60%. If the filament A is larger than this ratio, the fabric will have a soft feeling but will not have a firm feeling on the whole. On the other hand, if the ratio is smaller than this ratio, a fabric will have a feeling of firmness but will have a rough feeling as a whole, and will not have a soft feeling. Become. In the mixed yarn of the present invention, the difference ΔWsr in the hot water shrinkage Wsr between the filament A and the filament B must be 5% or more, preferably 10 to 20%. ΔW
If sr is less than 5%, a sufficient bulging feeling cannot be expressed in the heat treatment after weaving.

Further, in the present invention, filament A
Of hot water shrinkage Wsr (A) is 5% or less and Dsr
It is preferable that (A) −Wsr (A) ≦ 3. Ws
r (A) exceeds 5% and Dsr (A) -Wsr (A)> 3
In this case, the heat treatment after weaving may cause excessive shrinkage to easily give a fluffy texture, which may result in a lack of a suitable bulge. In addition, the shrinkage rate Wsr (B) of the filament B is 10% or more and Dsr (B) -Ws.
It is preferable that r (B) ≧ 3. Wsr (B) is 1
When it is less than 0 and Dsr (B) -Wsr (B) <3, sufficient shrinkage does not occur in the heat treatment after weaving, and a swelling feeling,
There may be a lack of softness. The hot water shrinkage ratio, the dry heat shrinkage ratio and the number of entangled parts in the present invention are values obtained by the following method. Hot water shrinkage (Ws
r): Take a ridge of 10 turns under a tension of 1/20 g / dr, apply a load of 1/20 g / dr to the ridge, and length l before contraction.
Is measured. Then, after removing the load, the film is passed through the polyester knitted net and soaked in hot water at 100 ° C. for 10 minutes, the surface water is wiped off, and the film in the net is taken out and dried. After air drying, a load of 1/20 g / dr is applied and the length l'after contraction is measured. Hot water shrinkage (Wsr) = {(l-l ') / l} × 100 (%) Dry heat shrinkage (Dsr): 1 under tension of 1/20 g / dr
Take a wound wound 0 times, apply a load of 1/20 g / dr to the wound and measure the length 1 before contraction. This drip is hung in a constant temperature dryer at 200 ° C and left for 10 minutes, then taken out 1/20 g / dr
And the length l'after contraction is measured. Dry heat shrinkage (Dsr) = {(l-l ') / l} x 100 (%) Entangled part number: The number of entangled parts per 1 m under 0.1 g / dr tension, which is an appropriate needle in the mixed fiber. Is stabbed, and the length of movement in the yarn direction is measured at 100 locations in total, and the average value (DL; unit mm) is calculated and expressed as 1000 / DL = number of interlaced parts (pieces / m).
