本発明はポリエステル繊維の周囲を木綿繊維で被覆した
二層構造を呈する複合糸の製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a composite yarn having a two-layer structure in which polyester fibers are surrounded by cotton fibers.

優れた木綿繊維で被覆することにより長短相補う試みに
ついては従来既に公知である。Polyester fiber, which has features such as thermoplasticity, quick drying, and compressive elasticity, has drawbacks such as generation of static electricity due to its hydrophobicity and lack of sweat absorption, so it should be covered with cotton fiber, which has excellent moisture absorption and dyeability. Attempts to compensate for length and shortness using the following method have already been known.

でもって被覆する方法が開示されている。Regarding the manufacturing method of such composite yarn, Japanese Patent Publication No. 56-11775
In the publication, a sliver of polyester fiber to be the core is fed to the outside as seen from the flyer head of a roving frame, and a sliver of cotton fiber to be the covering to the inside is fed from a back roller in a co-moving state, and the front roller A method is disclosed in which the fiber is bent at an oblique angle of 0 to 600 to reach the flyer of a roving frame, and the core fiber is covered with a covering fiber during this time.

不便を伴った。However, in this method, as described in the above publication, in order to completely cover the core sliver with the sliver, the spinning force of the core sliver must be higher than that of the sliver. In addition to being difficult to manage in that the sliver does not flow, it is also inconvenient in that it requires a draft portion roller width that is large enough to feed both slivers simultaneously.

糸を木綿繊維で被覆する方法が開示されている。Furthermore, in Japanese Patent Application Laid-Open No. 55-116824, polyester fibers, which are core fibers in the form of rovings, are fed between the back roller and surf roller of a roving machine, or between the third roller and second roller, and then passed through the roving machine. A method is disclosed in which the cotton fiber slivers are overlapped approximately in the center, and then the two are drafted together, and after coming out of the front roller, they are brought straight to the flyer of the roving machine, during which time the polyester fiber rovings are covered with the cotton fibers. ing.
しかし、この方法では芯部となるポリエステル繊維粗糸
の撚りのブレークが不完全なためにドラフトされない傾
向を示す欠点があった。However, this method has the drawback that the polyester fiber roving serving as the core portion tends to not be drafted because the twist break is incomplete.
芯部となるポリエステル繊維はスライバーの形態である
よりも粗糸の形態である場合の方が粗紡機機構上遥かに
取扱い容易といえる。It can be said that it is much easier to handle the core polyester fiber in the form of roving than in the form of sliver due to the mechanism of the roving machine.
そこで本発明者等は、これ迄、この場合についてのより
優れた製法について鋭意研究を重ねてきた。Therefore, the inventors of the present invention have been conducting intensive research on a more excellent manufacturing method in this case.

すかという重ね合わせ位置の特定によつて、その効果は
大きく左右されることがわかった。As a result, we determined the interrelationship of the twisting directions of the polystellate fiber yarn and composite roving, which form the core, as well as the overlapping position of where the polyester fiber roving should be overlapped with respect to the width of the cotton fiber sliver. It was found that the effect was greatly influenced by
本発明は上記した知見に基づき完成を見るに至ったもの
である。The present invention has been completed based on the above findings.
本発明を図面にしたがって説明すると、つぎのとおりで
ある。The present invention will be described below with reference to the drawings.
被覆部となる木綿繊維スライバーAは供給ローラ1より

でそれぞれドラフトをかげる。The cotton fiber sliver A that will become the covering part is supplied from the supply roller 1, passes through the trumpet 2, and then is placed between the back roller 3 and the third roller 4, and between the third roller 4 and the second roller 5.
and between the second roller 5 and the front roller 6.

トをかける。On the other hand, the polyester fiber roving B that will become the core is fed from the rear of the second roller 5 after passing through the trumpet 7, which is positioned as described below, and is laid on the flattened cotton fiber sliver A, and then the second roller 5 and the front roller 6 together with the cotton fiber sliver A.
こうして木綿繊維スライバーAとポリエステル繊維の粗
糸Bとが重なり合った複合スライバーは、軸線Y−Y’
に対して成る斜行角度θでもって折れ曲ってフライヤー
8に至る間に撚りがかけられ、目的とする複合粗糸Cを
得る。In this way, the composite sliver in which the cotton fiber sliver A and the polyester fiber roving B are overlapped has an axis Y-Y'
The yarn is bent at an oblique angle θ relative to the yarn and twisted while reaching the flyer 8 to obtain the desired composite roving C.
この発明は上記した複合粗糸を製造し、次いで該複合粗
糸を精紡する複合糸の製法において、下記の二点をその
特徴とするものである。The present invention is a composite yarn manufacturing method in which the above-described composite roving is manufactured and then the composite roving is spun, and is characterized by the following two points.
すなわち、第1点は複合粗糸Cの撚り方向について、ポ
リエステル繊維粗糸Bの撚り方向とは逆の関係とする点
である。That is, the first point is that the twisting direction of the composite roving C is opposite to the twisting direction of the polyester fiber roving B.
このため、ポリエステル繊維の粗糸BがS撚りで複合粗
糸Cが2撚りであるか、またはポリエステル繊維粗糸B
が2撚りで複合粗糸CがS撚りであるかの二態様である
。For this reason, the polyester fiber roving B is S-twisted and the composite roving C is 2-twisted, or the polyester fiber roving B
The composite roving C has two twists, and the composite roving C has S twist.
第2点はトランペット7の位置、換言すれば平らに拡が
った木綿繊維スライバーA上に重ねるポリエステル繊維
粗糸Bの供給位置についてである。The second point concerns the position of the trumpet 7, in other words the feeding position of the polyester fiber roving B which is superimposed on the flattened cotton fiber sliver A.
複合スライバーの斜行方向は、Z撚りの複合粗糸を製造
すると垣は第3−A図の如くにし、S撚りの複合粗糸を
製造するときは第3−B図の如(にし、本発明では、木
綿繊維スライバーAの巾をほぼ三等分して、斜行方向と
同じ側にあるスライバ一部分イ、中央のスライバ一部分
口、および斜行方向とは反対側にあるスライバ一部分ハ
と呼ぶならば、このスライバ一部分ハのほぼ中央に相当
する位置にトランペット7を設置し、こうしてポリエス
テル繊維粗糸Bの供給位置を決めるのである。The diagonal direction of the composite sliver is as shown in Figure 3-A when manufacturing a Z-twisted composite roving, and as shown in Figure 3-B when manufacturing an S-twisted composite roving. In the invention, the width of the cotton fiber sliver A is divided into three equal parts, and the part of the sliver on the same side as the diagonal direction is called A, the part of the sliver in the center is called the opening, and the part of the sliver on the opposite side to the diagonal direction is called C. Therefore, the trumpet 7 is installed at a position corresponding to approximately the center of this sliver portion C, and the feeding position of the polyester fiber roving B is determined in this way.
フロントローラ6のニップ点から複合スライバーが斜行
する斜行角度θについては、粗紡機自体の関係寸法から
定まるものであるが、一般には25°〜60°の範囲と
いえる。The oblique angle θ at which the composite sliver obliquely travels from the nip point of the front roller 6 is determined from the related dimensions of the roving frame itself, but it can generally be said to be in the range of 25° to 60°.
ポリエステル繊維粗糸Bの撚係数が0.38以下だとボ
ビンバンガーより吊り下げられているポリエステル繊維
粗糸Bが引き出される際の張力で素抜げが生じ易いし、
また撚係数が0.66以上だと得られた複合粗糸Cを精
紡の際ドラフト不良を生ずるから、撚係数は0.40〜
0.65の範囲とすることが好ましい。If the twist coefficient of the polyester fiber roving B is 0.38 or less, the tension when the polyester fiber roving B suspended from the bobbin banger is pulled out tends to cause it to come loose.
In addition, if the twist coefficient is 0.66 or more, draft defects will occur during spinning of the obtained composite roving C, so the twist coefficient should be 0.40 to 0.40.
The range is preferably 0.65.
上記のとおり、本発明では複合粗糸Cの撚り方向をポリ
エステル繊維粗糸Bの撚り方向とは逆としたから、フロ
ントローラ6のニップ点を出た所で粗糸Bは撚り戻りを
生じてバック気味となるから木綿繊維スライバーAとの
喰い込み交絡が良好であり、したがって精紡時にドラフ
トされないという現象は全(ない。As mentioned above, in the present invention, since the twisting direction of the composite roving C is opposite to the twisting direction of the polyester fiber roving B, the roving B is untwisted when it leaves the nip point of the front roller 6. Since it tends to back, the biting and intertwining with the cotton fiber sliver A is good, and therefore there is no phenomenon of drafting during spinning.
これに反して両組糸B、Cの撚り方向を同一とするとぎ
には、前記した粗糸Bのバックは全く期待できないばか
りか粗糸Bの撚りは強(なるため、木綿繊維スライバー
Aとの交絡が悪く、精紡時にドラフト不良、スラブ発生
が多いといった不都合を生じる。On the other hand, if the twisting direction of both braided yarns B and C is the same, not only the back of the roving yarn B described above cannot be expected at all, but also the twisting of the roving yarn B will be strong (because it will become similar to the cotton fiber sliver A). This causes problems such as poor drafting and frequent occurrence of slabs during spinning.
つぎに本発明では木綿繊維スライバーAの巾をほぼ三等
分することによって得られたスライバ一部分のうち、フ
ロントローラ6から出た複合スライバーの斜行方向とは
反対側のスライバ一部分ハのほぼ中央を、セカンドロー
ラ5からのポリエステル繊維粗糸Bの供給位置としたか
ら、得られた複合粗糸Cの構造は粗糸Bが完全に中心部
を占め、その周囲を木綿繊維スライバーAで均一に被覆
されたものとすることができる。Next, in the present invention, among the parts of the sliver obtained by dividing the width of the cotton fiber sliver A into three equal parts, the part of the sliver on the opposite side to the diagonal direction of the composite sliver coming out from the front roller 6 is approximately at the center of the part C. is the feeding position of the polyester fiber roving B from the second roller 5, so the structure of the obtained composite roving C is such that the roving B completely occupies the center and the cotton fiber sliver A uniformly surrounds it. It can be coated.
これはフロントローラ6から出てフライヤー8に至る複
合スライバーの紡出張力は、複合スライバーの斜行方向
とは同側のスライバ一部分イよりも中央のスライバ一部
分口、中央のスライバ一部分口よりも上記斜行方向とは
反対側のスライバ一部分ハが高いから、張力の強いスラ
イバ一部分への周りにこれよりも張力の弱いフライバ一
部分口およびイが巻きつき完全に被覆するからである。This means that the spinning force of the composite sliver coming out of the front roller 6 and reaching the flyer 8 is higher than that of the central sliver part A on the same side as the diagonal direction of the composite sliver, and more than that of the central sliver part A. This is because the portion of the sliver on the side opposite to the oblique direction C is high, so the portion of the sliver having a higher tension is wrapped around the portion of the sliver having a lower tension and is completely covered.
これに反して粗糸Bをスライバ一部分イに供給したとす
ると、粗糸Bが複合粗糸Cの表面に顕出するほど偏寄す
る。On the other hand, if the roving B is supplied to a portion of the sliver A, the roving B is biased so that it is exposed on the surface of the composite roving C.
またスライバ一部分口に供給したとすると、複合粗糸C
の表面に顕出するほどではないにしても中心をはずれた
片側に偏寄したものしか得られない。Also, if a part of the sliver is supplied to the mouth, the composite roving C
Even though it is not as noticeable as it appears on the surface, it can only be obtained that is off-center and biased to one side.
本発明の実施例を以下に示す。Examples of the present invention are shown below.

Prepare 15 yards of S-twisted polyester fiber roving B, use the apparatus shown in Figures 1 and 2, set the oblique angle θ to 45°, and change the twist coefficient by twisting 2 twists with the flyer 8. Composite roving C with a weight of 0.36 and a roving weight of 180 gelens/15 yards was obtained.

When a dyeing test was carried out using a dye (Household Dyes Directly Miya Furusu #4011 manufactured by Katsuraya Co., Ltd.), it was found that in the product of the present invention, there were almost all polyester fibers in the core that were not dyed by the above dyes, and dyed cotton fibers In contrast, with products other than the products of the present invention, the undyed polyester fibers were scattered on the surface of the dyed coated yarn, and even though it was not so much, it was unevenly distributed on one side.
