本発明はポリエステル100%又は他の!inとの混紡
に使用される紡績用ポリエステル短繊維に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is made of 100% polyester or other polyester! This invention relates to short polyester fibers for spinning used for blending with in.
ポリエステル短繊維を使用して紡績糸となし。 Spun yarn and none using polyester short fibers.
該紡績糸1を用いた布帛は1.ふくらみに欠け、ソフト

として長年問題となっていた。 このペーパーライク
な風合は該ポリエステル短繊維と他のwA$1とを混紡
して得られるt=紡糸の場合にも問題であり、1級品位
の布帛を得ることができなかった。The fabric using the spun yarn 1 is 1. It has been a problem for many years as it lacks fullness, lacks a soft feel, and has a so-called paper-like texture. This paper-like feel is also a problem in the case of t=spinning obtained by blending the polyester short fibers with other wA$1, and it was not possible to obtain a fabric of first grade quality.
この欠点をカバーするために、ポリエステル短IIIに
繍デニールのものを使用する試みがなされている。

。ざらに繍デニールのポリエステル短繊維、特にその単
糸デニールが。In order to overcome this drawback, attempts have been made to use polyester short III with embroidered denier.
In this way, fabrics using polyester staple fibers of high denier have a TPI, soft F2 texture, but on the other hand, they lack fullness, and they also lack resilience, which is a characteristic required for fabrics. A new problem is emerging. Roughly embroidered denier polyester short fibers, especially its single denier.
1 、Od e以下のポリエステル短繊維では開繊工程
であるカード工程において、ネップやムラが発生し、こ
のため、カード工程のドツファ−回転数を低下せしめる
等の対策をとっても充分でなく。1. With polyester short fibers having an Ode or less, neps and unevenness occur in the carding process, which is the opening process, and therefore, even if measures such as lowering the docker rotation speed in the carding process are taken, it is not sufficient.
生産性が著しく低下し問題である。This is a problem as productivity drops significantly.
他の方法として、デニールft変えることなくカット長

紡績糸の構成本数を変えずにカット長のみが短くなるの
でti!3蹟糸強力が低Tするという欠点がある。As another method, attempts have been made to blend different cut lengths by changing only the cut length without changing the denier ft (EP2419B publication), but although this method slightly improves the fullness of the fabric, it lacks a soft feel. Furthermore, only the cut length can be shortened without changing the number of spun yarns, so ti! There is a drawback that the 3-strand yarn strength is low T.
又、さらに進んだ方法として長カット長の太デニール1
a維と短カット長の纏デニール繊維を紡績工程で混紡す

号公i) この方法では前述の方法に比べて改良され
てはいるが、紡績糸の均斉度、鳳合の点で不充分てあり
、生産性が低下するという欠点は解決されていなかフだ
。In addition, as a more advanced method, thick denier 1 with a long cut length is used.
A method has been proposed in which A-fibers and short-cut denier fibers are blended in the spinning process. (Unexamined Japanese Patent Publication No. 59-26537
Publication No. i) Although this method is improved compared to the above-mentioned method, it is still insufficient in terms of the uniformity and fusion of the spun yarn, and the drawbacks of reduced productivity remain unsolved. .
これは構成1anとして繍デニール繊維を使っている上
、am間のデニール差が大きく通常の紡績工程における
混合方法、即ち打綿工程か線条工程において混合する方
法では繊維間のなじみが不良になるためと考えられる。This uses embroidered denier fibers as configuration 1an, and there is a large denier difference between ams, so if the mixing method is used in the normal spinning process, that is, the mixing method in the batting process or the filament process, the blending between the fibers will be poor. It is thought that this is because of this.

ることを目的とする。The present invention solves the problems of the conventional spinning process and enables uniform blending while maintaining high productivity in a normal spinning process, which has not been possible in the past. The purpose of the present invention is to provide short polyester fibers that enable the production of fabrics that have fullness and soft texture.

You can use a 391 denier one! It is essential. A more preferable range of single yarn denier D2 is 0.8≧D2≧0.4, but in any case, in order to obtain a yarn with a soft texture, a fine denier must be used. It is not preferable to use threads with a thread denier D2 of 0.4 beak because the passability in the carding process will be reduced.

Noil! Use the thick denier ones in the box. If Dl exceeds 1.8 d e, the texture will be rough and the texture will be rough.

When m is mixed with polyester short fibers of a bundle denier in which the single yarn denier D2 is within the above range in a clogging spinning process, it tends to behave in its own way, is not mixed uniformly, and tends to cause yarn unevenness. What is the cause of this phenomenon?
I'm not sure.
その原因の1つとして、IMデニールD2の範囲が前記
のような場合には、該細デニール繊維の表面積が著しく
増加し、m維相互のR擦が大となり。One of the reasons for this is that when the IM denier D2 is in the above range, the surface area of the fine denier fibers increases significantly, and the R friction between the m fibers becomes large.

This is thought to be due to poor fitting of No. 11. IJ like this! In order to overcome the defects caused by defects, it is necessary to transfer the polyester short fibers from the N manufacturing process to the spinning process! It is effective that two or more types of short polyester fibers are blended in the wrapper, preferably substantially uniformly. In the spinning process, the molten polymer is discharged from a nozzle of a spinneret and collected as a yarn sub-tow.In the second drawing process, a large number of the above-mentioned sub-tows are bundled with a yarn creel to form a raw yarn tow. After heating and stretching, tension heat setting and crimping are applied.

Methods for uniformly mixing two-denier short polyester fibers of the same cut length in these processes are: - A method of spinning and blending fibers of different deniers using the same spinneret with nozzles of appropriate dimensions. ■Spinning machine') Attach a spinneret at the weighing position and spin the yarn? It is desirable to adopt the methods described in H., (1) a method in which raw yarns of different deniers are spun in each spinning machine, and raw yarns of different deniers are iffed using a yarn creel in the drawing process, as well as silk combinations of these methods. . Particularly from the point of view of uniform fibers, methods (1) and (2) above are desirable.

That is, tow Y1 made of thick denier fibers and tow Y2 made of fine denier fibers, which have been separately crimped, crimped and heat-set, are sewn with kite rollers G+ and G2 under high tension with tension bars TI and T2. to separate cutters CI and C2 and separate! lllll

S2とをより均一に混合することができる。It is obtained by a method of mixing and dropping onto a conveyor 2 driven by rollers 4. Note that 3 is a compressed air outlet. By supplying the tow to the cutter with high tension, the tow can be easily opened, and the thick denier fiber S1 and the denier bundle S2 can be mixed more uniformly.

This is not preferable because it becomes difficult to mix with thick denier fibers.

As a measure of uniform mixing in the packing bale, 100g of gauzen was sampled from corner parts 5 to 12 indicated by the circles in Figure 2, and each part was placed on a flat card to create slivers, and the first sliver and the last sliver were For each sliver, calculate the ratio of the number of slivers for each denier from a micrograph of one cross-section of the sliver. It is preferable that all the fibers are included in the sample.In particular, the average value of the 8 parts and the ratio of the number of fibers by denier of the samples obtained from each part of 5 to 12, and the average value of each part It is preferable that the difference between the values is within 30% of the average value.

短繊維の繊維長L!を長くすることにより、この問題が
軽減されることを見出した。The denier D and fiber length can be selected so as to satisfy the formula (6), but in particular, polyester short polyester with a denier of 'a' has traditionally had poor passability in the carding process and is prone to neps and unevenness. In order to reduce such neps and unevenness, the fiber length L 2 (m −TI ) should be shortened according to the denier, for example in 1911.
If D2=0.4de, the fiber length is 32.4≧L
Those between ≧14.08 are used. If the same thick denier short polyester fiber is used as the thick denier short polyester fiber to be mixed with this, yarn unevenness will occur, which is thought to be caused by the above phenomenon. ! It has been found that this problem can be alleviated by making the length longer.

。Furthermore, if the length 2 of the denier polyester short fibers is shortened, neps and unevenness can be reduced as described above, but
On the other hand, if the mu length becomes short, the fiber arrangement of the wrapped denier polyester short fibers cannot be increased in the blended yarn, and there is a problem that the gloss of the blended yarn is significantly reduced.

Compared to blended cotton in the conventional spinning process, #j
In the i-weaving process, we were able to improve productivity and quality of the spun yarn, and in the final mW product, we were able to achieve both softness, drapability, and resilience that could not be obtained with conventional technology.
