［産業上の利用分野］
本発明はミシン糸に関し、特に千鳥縫ミシン等に好適に
用いられるミシン糸に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sewing thread, and particularly to a sewing thread suitably used in a zigzag sewing machine or the like.
［発明の背景］
従来のミシン糸はＳ方向に施撚した複数本の単糸を、Ｚ
方向に合撚して、実質的にトルクを相殺せしめたミシン
糸が多く用いられている。[Background of the invention] Conventional sewing thread consists of multiple single threads twisted in the S direction,
Sewing thread is often used which is twisted in both directions to substantially cancel out the torque.
しかし、かかる撚構造からなるミシン糸には、以下に説

糸に割れたりして、糸切れ、めとび等のｉ製トラブルを
生ずる。However, sewing thread having such a twisted structure has major drawbacks as described below. That is, during sewing, the sewing thread is partially and instantaneously untwisted by being squeezed with a sewing machine needle, sewing machine hook, etc.
Torque is generated by ply twisting, and the single threads that make up the sewing thread are broken, resulting in i-manufactured troubles such as thread breakage and skipping.
特に千鳥縫ミシンにおいて、この現象は顕著であり、従
来から大きな問題となっていた。This phenomenon is particularly noticeable in zigzag sewing machines, and has been a major problem for some time.
この欠点を解消するためには一般にボンド糸と称される

ンド糸を使うて縫製すると該ボンド系はミシン針やミシ
ン釜でしごかれて樹脂が脱落する場合があり、この脱落
した樹脂は特にミシン釜に多く付着してミシンの調子を
狂わして各種の縫製トラブルを発生さすことである。In order to overcome this drawback, sewing thread, generally referred to as bond thread, has been proposed. The bond thread is a sewing thread coated or impregnated with an adhesive resin to prevent the sewing thread from being partially untwisted. Although the bond yarn is certainly effective in preventing partial untwisting of sewing thread,
New shortcomings have been revealed. One is that it not only requires special equipment to coat or impregnate the sewing thread with adhesive resin, but also requires an extra process, which increases the manufacturing cost of the sewing thread.The second drawback is that When sewing with this bond thread, the resin may fall off as the bond thread is squeezed by the sewing machine needle or sewing machine hook, and this dropped resin may stick to the sewing machine hook in particular and cause the sewing machine to malfunction. This causes various sewing problems.

は接着性を増加させトラブルを生じる。In the case of the sewing thread described in JP-A No. 59-173333, binder fibers must be placed on the surface of the thread due to its purpose and effect, and for this reason, it is exposed to heat during the sewing thread manufacturing process. Binder fibers in sewing threads adhere to each other during processes such as twist-setting and dyeing processes, causing problems. Further, even during sewing, the temperature of the sewing machine needle increases due to high-speed operation, which increases the adhesion of the sewing thread, causing trouble.

The purpose of the present invention is to propose a sewing thread with a special structure that can be obtained at low manufacturing cost.

The temperature is preferably 0°C or higher. The composite III multifilament yarn is a necessary component in the core to maintain strength. The ingredients used in the sheath are not very strong, and on their own,
Therefore, in order to maintain the structure of the sewing thread of the present invention, it is preferable to use a high-strength polyester with a high melting point because it cannot withstand various tensions during the manufacturing process of the sewing thread. . The polyester of the core is preferably a polymer in which 80% by weight or more of the main repeating units are polyethylene terephthalate.

Further, the component ratio between the core and the sheath is not particularly limited, but a weight ratio of about 1:1 can be suitably exemplified.

生させない上限が３０重量％なのである。The composite m-fiber multifilament yarn used in the present invention must be in an amount of 3 to 30% by weight based on the weight of the sewing thread. If the content of the composite II miscellaneous multifilament yarn is small, no effect will be produced, and the lower limit of this is 3% by weight. However, on the other hand, if the content of the composite RAN multifilament yarn is too high, thermal adhesion will occur in the sewing thread, resulting in the following problem. That is, when the sewing thread is wound around a bobbin or the like and heat-treated during the sewing thread manufacturing process, melt adhesion occurs between the sewing threads, resulting in poor unwinding properties and problems in the sewing machine manufacturing process. Also, even during sewing using sewing thread,
The sheath of the composite fiber multifilament yarn melts due to the heated sewing machine needle, increasing the frictional force of the sewing thread and causing problems such as sewing thread breakage.The upper limit to avoid such problems is 30% by weight. That's why.
本発明のミシン糸はポリエステルマルチフィラメント糸
に下撚を施した単糸複数本、又はポリエステルスフ紡績
糸の単糸複数本と無撚の該複合繊維マルチフィラメント
を単糸の撚方向と逆方向で合撚することが重要である。The sewing thread of the present invention is made by combining multiple single yarns of polyester multifilament yarn with a first twist, or multiple single yarns of polyester spun yarn and untwisted composite fiber multifilament in the opposite direction to the twisting direction of the single yarns. It is important to combine and twist.

配置させるためである。撚を有する単糸と無撚の該複合
繊維マルチフィラメント糸を単糸の撚方向とは逆方向で
合撚すると撚を有する単糸は解撚されて糸長は伸びる。By using this plying/twisting method, the composite fiber multifilament yarn having thermal adhesive properties is mainly arranged inside the sewing thread, and the polyester filament type or polyester spun yarn which does not have thermal adhesive properties is arranged outside the sewing thread. It's for a reason. When a twisted single yarn and an untwisted composite fiber multifilament yarn are combined and twisted in a direction opposite to the twisting direction of the single yarn, the twisted single yarn is untwisted and the length of the yarn is elongated.
逆に無撚の該複合繊維マルチフィラメント糸は加熱され

部に配される。On the contrary, the untwisted composite fiber multifilament yarn is heated to shorten the yarn length (shrink by M). As a result, a dimensional difference occurs in yarn length between the single yarn and the composite fiber multifilament yarn, and in the twisted yarn, the composite fiber multifilament yarn with a short yarn length is inside the polyester multifilament yarn with a long yarn length. The yarn or spun polyester yarn is placed on the outside.

Heat treatment is performed under the following conditions. As explained above, this heat treatment is intended to fix the twist of the sewing thread with the heat-adhesive composite 1M multifilament system. 140
℃ for 30 minutes) and the dyeing process (generally carried out at a temperature of 130℃), it is necessary not to increase the manufacturing cost of sewing thread.

防止することが出来る。(Function of the Invention) As described above, the sewing thread of the present invention has a structure in which the composite fiber multifilament system is mainly arranged in the inner layer of the sewing thread, and at least a part of the composite fiber multifilament is melt-bonded. Therefore, during sewing, the twist is partially untwisted by squeezing with a sewing machine needle or sewing machine hook,
It is possible to prevent troubles such as single thread cracking, thread breakage, and skipped stitches of sewing thread.

ブルも発生しない。Furthermore, in the sewing thread of the present invention, since the composite fiber multifilament yarn is arranged in the inner layer of the thread, troubles may occur during the process where the low melting point polyester is exposed to heat during the manufacturing process of the sewing thread. Moreover, even during sewing, the adhesiveness of the surface of the sewing machine system does not increase due to the heated sewing machine needle, and troubles caused by this do not occur.
