Next, the polyester fibers must be composed of stable fibers of one equal length. Since the horizontal uniformity will not improve due to the cutting and stretching, the purpose is to avoid a decrease in the uniformity due to the stretching by using pieces that have been cut to equal lengths from the beginning.

・If the yarn is 0.1 denier, the uniformity will improve, but the strength as a spun yarn will drop significantly, so it is not preferable (,4
This is because if the denier exceeds 0 denier, the intertwining properties will decrease, making spinning difficult and reducing the uniformity. ) Here, the manufacturing method of the present invention will be explained.

First, kaolinite is added to a polyester whose main repeating unit is ethylene terephthalate, for example, a copolyester ρ containing 80 moA/% or more of ethylene terephthalate units, and preferably 1.3 to 5.0 weight, preferably 1.
.. A tow made of polyester fiber containing 5 weight or more and 4.0 weight or less is cut into equal lengths to obtain raw cotton. Next, this raw cotton is passed through the usual processes such as a mixing machine, a carding machine, and a filament machine to form sliver, and if necessary, it is passed through a roving machine to form roving yarn.

Although interlacing + real twisting and other methods have been proposed, the present invention is not limited to any of these methods and can be used alone or in combination of several methods. Of course, when making the stable fiber bundle into a spun yarn, it is also possible to combine it with continuous multifilament yarn or processed yarn, and in that case, continuous multifilament yarn or processed yarn with a fineness thicker than that of the stable fiber can be used. 9. By using processed yarn, we can expect effects such as giving a stiff waist. Also.

Polyethylene terephthalate copolyester using sodium sulfoisophthalate has an average particle size of 0.3μ.
By adding various amounts of kaolinite, the spinning temperature was 290.
The fiber was spun at a winding speed of 1300 m/m. Pair this with thread,
A tow (500,000 denier) with a single fiber fineness of 1.0 denier was produced by drawing. Next, this tow was cut into staple fibers of equal length of 40 cm to obtain raw cotton. Next, this raw cotton is passed through a mixing machine, a carding machine, a filament machine, and a roving machine to make roving (
1,79 count) and then 40' on a ring spinning machine.
8 (English cotton count) spun yarn was produced. For comparison, a similarly spun yarn (40
'8) was produced in Experiment No. 1), and 1.0 gb of kaolinite was added to produce a 50,000 denier tow to produce a sliver of unequal length staple fibers with an average fiber length of 40 cm. A spun yarn (40'8) was produced in the same manner (experiment number 2).
