本発明は、−方の面が、天然繊維の被覆性に優れた布帛
構造を有する編織物およびその製造法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a knitted fabric whose negative side has a fabric structure with excellent coverage of natural fibers, and a method for producing the same.
近年、複合繊維に関する研究が盛んに行なわれている。 In recent years, research on composite fibers has been actively conducted.
その理由としては、消費者の多様なニーズを背景にした
多品種少量生産時代の要請に応じるには、繊維の複合化
が適していること、審美性と機能性の両方をより高度に
要求されること、単一の繊維素材ではこれに応じきれな
いことなどが挙げられる。The reason for this is that composite fibers are suitable for meeting the demands of the era of high-mix, low-volume production that is driven by the diverse needs of consumers, and that both aesthetics and functionality are required to a higher degree. This includes the fact that a single fiber material cannot meet these demands.
−方、天然繊維に対する評価の高まりは、生活優先と人
間性回復の風潮を背景として、自然回帰のファッション
傾向とともにますます根強いものとなっている。こうし
た背景をもとに、天然繊維が持つ風合、外観、吸湿性な
どの良さをそのまま保持しつつ、これに合成繊維が持つ
寸法安定性、防シワ性、強力などの優れた機能性が加味
された複合繊維が強く要望されている。On the other hand, the growing appreciation for natural fibers is becoming more and more entrenched, along with the fashion trend of returning to nature, against the backdrop of a trend of prioritizing life and restoring humanity. Based on this background, we have added the excellent functionality of synthetic fibers, such as dimensional stability, wrinkle resistance, and strength, while maintaining the good texture, appearance, and moisture absorption properties of natural fibers. There is a strong demand for conjugated fibers.
なかでもポリエステル繊維は、これら機能性が特に優れ
ており、綿、羊毛、麻、絹などの天然繊維との複合繊維
が数多く提案実施されている。Among these, polyester fibers have particularly excellent functionality, and many composite fibers with natural fibers such as cotton, wool, linen, and silk have been proposed and implemented.

強力、張り、腰、寸法安定性、均斉さなどを兼ね′備え
た理想的な複合形態といえる。Polyester fibers that are composited with natural fibers include continuous multifilament yarns and spun yarns, and the cross-sectional composite forms of composite fibers include -like mixtures, block mixtures, and core-sheath mixtures, and various types can be created depending on the combination. is obtained. Among these combinations, the core-sheath structure yarn, in which continuous multifilament yarns of polyester fibers are arranged in the inner layer of composite fibers and natural fibers are arranged in the outer layer, has the appearance and feel of natural fibers, and has the characteristics of continuous multifilament yarns of polyester fibers. It can be said to be an ideal composite form that combines strength, tension, stiffness, dimensional stability, and evenness.

さが生かされていないきらいがあった。またこの方法は
、高価な設備が必要でありコスト高であること、工程が
煩雑であること、加工張力の影響を受けやすく均斉性に
欠けることなどの欠点があった。Conventionally, in the manufacturing method of composite fibers in which continuous multifilament constitutes the core and natural fiber spun yarn constitutes the sheath, a core is placed at the center of the stretched natural fiber roving in the front roller section of the spinning process. Methods such as inserting a continuous multifilament yarn and heating it are known, but the problem is how to insert the core yarn into the center of the sheath roving. The coverage of the filament yarn was not sufficient, and the good texture and appearance of natural fibers were not utilized. Furthermore, this method has disadvantages such as requiring expensive equipment, resulting in high costs, complicated steps, and being susceptible to processing tension and lacking in uniformity.

形成後の布帛の表面の構造は、天然繊維の持つ外観、風
合を表現する上で特に重要視される。On the other hand, the method of combining continuous multifilament yarn and natural fiber spun yarn and twisting the yarn using a twisting machine is inexpensive because it uses a normal twisting machine, and is also excellent in terms of operability. There was a drawback that it was difficult to obtain a core-sheath structure yarn.There is also an attempt to use continuous multifilament with a high heat shrinkage rate using this twisting method to promote core-sheath structure formation by developing shrinkage after forming a &W fabric. However, with the usual heat treatment method, the coverage by the natural fiber spun yarn is not sufficient.In addition to the core-sheath structure of the composite fiber, the surface structure of the fabric after forming the knitted fabric depends on the nature of the natural fiber. It is particularly important in expressing appearance and texture.

するものである。In order to achieve the above-mentioned object, the present invention is a knitted fabric constructed using a single yarn consisting of natural fibers and synthetic fibers, one side of which is mainly composed of natural fibers, and the other side mainly composed of synthetic fibers. It is characterized by a knitted fabric composed of. In addition, as a manufacturing method for such a knitted fabric, a knitted fabric is formed using twisted yarns of natural fibers and synthetic fibers having a higher heat shrinkage rate than the natural fibers, and then substantially only one side of the knitted fabric is twisted. It is characterized by heat treatment.

時の収縮率を求めたものである。In the case of polyester fibers, such synthetic fibers with a boiling water shrinkage rate of 20% or more are those spun at a high speed of about 1500 to 4500 m/min, or those made with aromatic fibers such as aliphatic dicarboxylic acids such as sebacic acid, isophthalic acid, and phthalic acid. It can be obtained by copolymerizing a third component such as a group dicarboxylic acid or a dicarboxylic acid having an alicyclic group such as 1 and 2 cyclobutanecarboxylic acid. The boiling water shrinkage rate here is 4■/
The shrinkage rate was determined when the sample was treated with hot water at 98°C for 10 minutes under a load of d.

も好ましくない。As the yarn twisting means, known means such as Italy type, ring type, double twister, etc. can be used. Further, the number of twists of the twisted yarn is preferably 100 to 600 T/m, more preferably 200 to 500 T/m. If the number of twists is less than tooT/m, the cohesiveness as a twisted yarn is poor, and not only is it difficult to pass through the process during construction and weaving, but the yarn also lacks natural fiber coverage. - way,
If the number of twists exceeds 600 T/m, not only will the texture become rough and hard, but the running speed during twisting will be slow, which is unfavorable from a cost standpoint.

などを好ましく用いることができる。In the present invention, the thus obtained twisted yarns are used to form a woven or knitted fabric, and this knitted fabric is subjected to heat treatment to cause shrinkage. This heat treatment employs a heat treatment method that heats only substantially one side of the knitted fabric. Such a heat treatment method involves blowing a heating medium such as hot air, hot water, or steam only from one side, or bringing only one side into contact with a heating element, and a combination of these methods is also possible. In particular, heating one side of the knitted fabric is effective as the first heat treatment method that starts shrinkage.In order to completely develop shrinkage, after heating from one side, supplementary heat treatment such as normal dry heat, hot water, or steam is applied. It is also possible to use a heating method from both sides. As a means of heating only from one side,
Preferred methods include a method in which only one side of the knitted fabric is brought into contact with a heating body such as a cylinder dryer, a method in which a shower of hot water is blown from only one side, a method in which steam or hot air is blown only from one side, and the like.
本発明においては編織物の一方の面が（例えば表面）が

エステル繊維がまず裏面側で収縮が始まり、その収縮に
よる力が表面側に伝播し、表面側のポリエステル繊維を
裏面側に引き込むためと考えられる。The purpose of the present invention is to obtain a fabric structure in which one side (for example, the front surface) of the knitted fabric has excellent coverage of natural fibers, and heating from one side in the present invention refers to heating from one side of the knitted fabric (for example, the front surface). Refers to heating from the other side. The reason why heating from the back side allows the front surface to better cover natural fibers than the back side is because polyester fibers, which are highly shrinkable fibers, first start shrinking on the back side, and the force of the contraction is This is thought to be because it propagates to the front side and draws the polyester fibers on the front side to the back side.
従来、−般の加熱方法は両面からの加熱であり、表面と
裏面が同時に加熱されるため、天然繊維の被覆性が表面
、裏面ともほぼ同等になるが、これに対し本発明の片面
からの加熱によれば、天然繊維の被覆性が、表面と裏面
で異なる偏在した構造を有するものが得られる。Conventionally, conventional heating methods involve heating from both sides, and the front and back sides are heated at the same time, so the coverage of the natural fibers is almost the same on both the front and back sides. By heating, it is possible to obtain a structure in which the covering properties of the natural fibers are unevenly distributed on the front and back surfaces.
