点もあった。2. Description of the Related Art Stretchable bandages and supporters are widely used for wrapping and protecting arms, legs and the like or parts thereof. This is because it is easy to wear, and even if the arm or leg is moved, it does not shift and is difficult to remove. As an elastic bandage,
For example, a bandage made of a fabric using a stretchable yarn such as spandex in the longitudinal direction has been conventionally known, but this type of stretchable bandage not only easily causes fraying at the end but also when worn. It had the drawback of poor cushioning and lack of softness. In order to solve the above-mentioned drawbacks, the present inventors have laminated a fibrous web on a woven fabric using elastic yarns in the longitudinal direction in the longitudinal direction and entwined the web with the woven fabric by hydroentangling. After that, a bandage having elasticity and preventing fraying from the ends by removing tension in the longitudinal direction was examined. However, in the case of this bandage, since the stretchable yarn is fixed by the fibrous web in a stretched state, the stretch does not restore the original length even if the tension is removed, and sufficient stretchability cannot be obtained. It was Furthermore, it is desirable for the bandage to have a definite stop point at which the stretch stops when the bandage stretches to a certain extent, whereas in the case of the elastic bandage described above, the stretch stop point is clearly defined. However, there is also a drawback that the elastic yarn gradually extends close to the cutting limit.

The purpose is to provide a cloth that can be used as a dressing.

Can be achieved by a unidirectionally stretchable composite fabric, characterized in that it comprises a fibrous web entangled with the woven base fabric without substantially affecting its stretchability. Also,

チフィラメントの糸などから調製する。The stretchable yarn used in the composite fabric of the present invention is prepared from a yarn having latent crimpability. The yarn having the latent crimping property is, for example, a yarn composed of a composite fiber composed of resins of two or more components having different melting points, or a yarn composed of a fiber produced by applying a heat history to one side of the fiber. is there. The heat history can be given by, for example, an edged crimp method in which one side of the fiber is rubbed against a hot blade. The yarn having the latent crimp property develops the latent crimp by heat treatment. For example, in the case of a composite fiber, a latent crimp can be expressed by heat treatment by utilizing the difference in thermal shrinkage between the low melting point resin component and the high melting point resin component. When a latent crimping yarn develops latent crimps, the number of crimps increases and the apparent length becomes shorter. When the yarn is pulled, the crimps stretch and the yarn lengthens, and the yarn is released. Then, it becomes a stretchable yarn having so-called stretchability, which returns to a highly crimped state. When the elastic yarn is pulled, the crimp stretches and extends until the yarn becomes linear, but in order to pull further beyond that length, the pulling force which is substantially different from the tensile force up to that point is large. Requires tensile force. Therefore, the elastic yarn has a clear extension stop point, and the length of the elastic yarn in that state is referred to as "extension stop length" in the present specification. The latently crimpable yarn used in the present invention is prepared from, for example, a multifilament yarn composed of filaments having a so-called side-by-side structure in which two components of polyester / low melting point polyester are laminated side by side in a cross section.

くなったりするので好ましくない。The woven base fabric of the present invention is composed of the elastic yarns and the non-elastic yarns which are substantially orthogonal to the elastic yarns. The non-stretchable yarn is prepared from a yarn having no latent crimping property (that is, a yarn made of a fiber that does not undergo dimensional change at the crimp development temperature of the latent crimpable fiber). For example, when the latently crimpable fiber is made of a multifilament yarn of polyester / low melting point polyester, a multifilament yarn made of polyester filament is suitable. The basis weight of the woven base fabric can be appropriately selected depending on the use of the composite fabric of the present invention, but when it is used as a bandage, it is preferably 10 to 50 g / m 2 . If it is less than 10 g / m 2 , the elastic force may be small, so that the bandage may not be able to have sufficient elasticity. If it exceeds 50 g / m 2 , the weight becomes too large to be suitable as a bandage, or the relative In addition, since the amount of the fibrous web is decreased, the end portion is likely to be frayed and the cushioning property is poor, which is not preferable.

がでてくるので好ましくない。The composite fabric of the present invention is one in which a fibrous web is entangled with the woven base fabric. As the fibers forming the web, it is desirable to use fibers that do not undergo dimensional change at the crimp development temperature of the latently crimpable fibers. For example, polyester fiber, polypropylene fiber, acrylic fiber, rayon fiber, cotton fiber and the like. Also,
The web is entangled with the woven base fabric so as not to substantially affect the stretch of the stretchable yarn up to the stretch stop length. This can be achieved, for example, by entanglement of the fibrous web before heat-treating the yarn having latent crimp properties for adjusting the stretchable yarn to develop latent crimp. That is, since the fibers are entangled with the yarn before the latent crimps develop, they move together with the yarns to form a crepe as the crimps develop, so that when the elastic yarn is pulled, the crepe also stretches. The stretch of the elastic yarn is substantially unaffected by the fibrous web. The basis weight of the web can be appropriately selected depending on the use of the composite fabric of the present invention, but when used as a bandage, it is preferably 5 to 20 g / m 2 . 5
If it is less than g / m 2 , sufficient cushioning properties and softness cannot be obtained, and if it exceeds 20 g / m 2 , the entanglement of the constituent fibers of the fibrous web becomes strong and stretchability may be impaired. Not preferable.

繊維に付着している繊維油剤も洗い流すことができる。The composite fabric of the present invention can be prepared, for example, by the following method. First, a web composed of fibers having no latent crimping property is laminated on a woven fabric composed of yarns having latent crimping properties and yarns which are substantially orthogonal to them and have no latent crimping property. The web can be laminated to one or both sides of the backing. Subsequently, the web is entangled with the fabric.
It is preferably carried out by hydroentanglement. While fiber oils cannot be removed by entanglement means such as needle punching, hydroentanglement does not require the use of adhesives that can affect the skin and allows the use of base fabric fibers and webs. The fiber oil agent adhering to the fibers can also be washed away.

して、本発明複合布の優れた特徴の1つである。After hydroentangling, heat treatment is performed to develop crimp of latently crimpable yarns constituting the woven base fabric. When the latently crimpable yarn is crimped, the woven base fabric apparently shrinks in the direction of the latently crimpable yarn to form a crepe.
Along with this, the fibers of the fibrous web entwined with the woven fabric also crepe. On the other hand, in the case of the conventional stretchable cloth using the elastic yarn made of the elastomer, the length of the elastic yarn itself (the elastomer polymer itself) expands and contracts, so that the web fiber entangled in the stretched state is , Acts to prevent the shrinkage of elastomeric polymers. However, in the case of the latently crimpable yarn according to the present invention, the length of the yarn itself does not change and the crimping only apparently shortens the length of the fabric, so that the entangled fibers move together. When the crepe-generated composite fabric is pulled in the stretching direction, it stretches until the crepe disappears, that is, until there is no crimp before heat treatment, where it stops stretching and stretching, and beyond that, the force to destroy the composite fabric is increased. Does not stretch unless joined. This is one of the excellent characteristics of the composite fabric of the present invention, whereas the conventional stretchable fabric using elastic yarn or the like continues to stretch smoothly.

ーター、粘着シート用基材などに用いることができる。Further, according to the method of the present invention, the degree of crimping can be controlled by changing the conditions of heat treatment, and thus the expansion / contraction rate of the obtained composite fabric can be controlled. For example, in the case of a bandage, it is possible to create a product having appropriate elasticity according to the site of use. The shrinkage rate of the bandage in the stretching direction (longitudinal direction) is such that the length shrunk by heat treatment is 15 to 50% of the length before heat treatment. In the composite fabric (particularly bandage) according to the present invention, the yarn in the non-stretchable direction (width direction) has a non-latent crimping property, and therefore, even during the heat treatment for developing the crimping of the yarn in the longitudinal direction, No dimensional change and no width reduction. The composite fabric according to the present invention can be used as a bandage, a supporter, a base material for an adhesive sheet, and the like.

The hydroentangling treatment was performed under the conditions of 3 to integrate the fiber web into the woven base fabric. Then, the latent crimp of the multifilament yarn of latent warp of the warp was developed by performing heat treatment at a temperature of 130 ° C. in a state where tension was not applied to the cloth as much as possible. As the warp developed crimps and the number of crimps was increased, the apparent length was shortened, and along with this, the apparent length of the cloth was also shortened and crepes were formed. The length of the composite cloth contracted by the heat treatment was 45% of the length before the heat treatment. The obtained unidirectionally stretchable composite fabric can be stretched to the length before the heat treatment, and this becomes the elongation stop length. The length of the unidirectional stretchable composite fabric with respect to the extension stop length is 55%, and the extension ratio up to the extension stop length (100/55 × 100) is about 1.
It was 82%.

することができる。In the stretchable composite fabric of the present invention, since the fibrous web is entangled with the woven fabric fiber, the end face and the cut face are not easily frayed. Moreover, since it has good stretchability and there is a point at which stretching and crimping clearly stop, the fabric does not continue to stretch to the breaking limit point in accordance with the tensile force unlike the conventional stretchable fabric. .. Furthermore, it has cushioning properties when worn, and has a soft texture. According to the method of the present invention, the stretch ratio of the stretchable composite fabric can be freely set according to the application, and stretching or crimping exceeding the set range does not practically occur. Further, by utilizing the hydroentanglement, it is possible to manufacture the intended stretchable composite cloth without using a material such as an adhesive or a fiber oil which may affect the skin.

If it is less than g / m 2 , sufficient cushioning properties and softness cannot be obtained, and if it exceeds 20 g / m 2 , entanglement between the constituent fibers of the fibrous web becomes strong and stretchability may be hindered. Not preferable. When the composite fabric is particularly required to recover its original length after stretching, latently crimpable fibers may be used in the fibrous web. If a fiber that develops latent crimps at a temperature at which the elastic yarns used for the woven base fabric develop crimps is used, a process for developing latent crimps can be performed at the same time. The inclusion of fibers with a high crimp in the fibrous web can increase the stretchability of the composite fabric obtained from its coil-like structure.
