2. Description of the Related Art Conventionally, high density woven fabrics using synthetic fibers such as polyester and nylon multifilaments have been manufactured and commercialized and are widely used by consumers. The high-density woven fabric has excellent moisture permeability, water pressure resistance, tear strength, and soft and flexible texture, and its application in the field of sports clothing is particularly remarkable. The high-density fabric uses multifilaments with a relatively small single yarn fineness, and the warp of the fabric called the cover factor,
The coefficient that indicates the degree of clearance between the unit densities of the weft is 200
It can be obtained by weaving with high density of 0 to 3000 class. However, it is not easy to obtain a high-density woven fabric with excellent moisture permeability, water pressure resistance, and tear strength, and including the standard design of a high-density woven fabric, including a sweet twisted yarn, warp glue, warping, weaving, and weaving. High technology is required in each process. For example, in the standard design, the ratio of the cover factor of the warp to the weft is set to 5: 5 to 6: 4,
Weaving the warp without twisting, increasing the number of weft threads, making the fineness of the weft larger than that of the warp, increasing the warp tension in weaving to insert the weft, speeding the closing timing, and arranging in the loom layout. There are many points such as shortening the cloth and shortening the cloth fell.

The present invention will be described in detail below. The high-density woven fabric composed of the synthetic fibers of the present invention has a total cover factor of the warp and the weft of 2000 to 3000,
It is desirable that the total fineness of the warp yarn and the weft yarn is 40 decitex to 170 decitex and the single yarn fineness is 1 decitex or less. The cover factor is a coefficient indicating the degree of clearance between unit densities, and a high cover factor value indicates a small gap, that is, high compactness. In order to obtain excellent waterproofness, the water pressure resistance is 800 kP
a, more preferably 1000 kPa, and a cover factor of 2000 or more is necessary to satisfy these requirements. However, if it exceeds 3,000, the texture becomes hard, which is not preferable. Further, the total fineness is preferably a relatively thin filament in order to increase the denseness and to make the texture soft, and it is necessary to have 40 decitex or more and 170 decitex or less, and more preferably 50 decitex or more and 160 decitex or less. However, if it is less than 40 decitex, the tear strength of the woven fabric becomes weak, which is not preferable. The single yarn fineness is also 1 decitex or less, and more preferably 0.7 decitex or less, in order to increase the denseness. The number of filaments is not particularly mentioned, but it is preferably at least 70 or more, more preferably 100 or more. As for the method for producing a synthetic fiber having a fine single yarn fineness, either single-component spinning or composite spinning may be employed, but the direct spinning method is preferably employed in view of production cost and environmental problems.

The warp yarns constituting the high-density woven fabric of the present invention are required to be untwisted or sweet twisted with a twist coefficient of 5000 or less. High-density fabrics are usually pressed at a dyeing factory in a calendering process to flatten the fibers to reduce the gaps between the tissues. Therefore, the higher the twist number of the warp yarns, the more the fiber converging property is increased, and the fibers are less likely to be flattened in the calendering process. Therefore, the twist number is preferably low, and the more preferable range is no twist or the twist coefficient is 3.
It is 000 or less. It is needless to say that it is preferable that the number of twists of the weft yarn is non-twisted or that the twisted yarn has a twist coefficient of 5000 or less in order to further flatten the fiber. And when applying a sweet twist, an Italian twisting machine classified as an up twister,
Weaving is prepared using a general twisting machine such as a ring twisting machine, a twisting machine, or a double twister classified into a large up twister and a down twister. A double twister having excellent properties is preferably used. When weaving without twisting, it is preferable to subject the synthetic fibers to mixed entanglement, and the degree of mixed entanglement is 20 pieces / M or more, 100 pieces /
M or less is preferable, and more preferably 40 / M or more, 8
It is 0 / M or less, and within this range, there will be no problem in the process passability in the twisting and weaving processes.
However, if it exceeds 100 M / M, it is not preferable because it causes a texture hardening and an unfavorable uneven appearance. As the mixed fiber entanglement means, an air entanglement nozzle is preferable, and an interlacer nozzle or a Taslan nozzle is preferable.

Further, it is necessary to sizing or sizing the warp yarns which are untwisted or which are subjected to a sweet twist having a twist coefficient of 5000 or less, by using an acrylic sizing agent. Since the warp yarn of the present invention uses a filament having a relatively small single yarn fineness, it easily fluffs, and the sizing and sizing are insufficient to bundle the filament, and the filament is protected by sizing and sizing. It is necessary to hold and fluff. The twisted yarn also plays the role of torque and anti-rattle. Acrylic glue refers to polyacrylic acid ester, sodium polyacrylate, etc., but in particular, a sizing agent containing an acrylic acid ester copolymer or an acrylic acid ester copolymer derivative as a main component, of which an ammonia salt type is preferable. As a general property of acrylic glue, the adhesive strength to hydrophobic fibers such as synthetic fibers is the highest among synthetic glues, and since the glue film is flexible and elastic, it can be said that it is the most suitable glue agent for the present invention. In particular, acrylic ester copolymer can easily obtain a paste with various properties by changing the ester group, which is necessary for the paste such as adhesiveness, hygroscopicity, film strength, and adhesiveness. It is a sizing agent with a good balance of the properties considered to be. However, although there is a soda salt type acrylic adhesive, it is not suitable for the present invention because of its low water resistance. It is desirable that the concentration of the sizing agent is 3% or more and 18% or less, and 3
If it is less than 18%, the adhesive strength to the synthetic fiber is reduced, and since it contains a large amount of water, the drying efficiency is poor. On the contrary, if it exceeds 18%, the penetrability of the sizing agent between the synthetic fibers is deteriorated and the binding strength is deteriorated. Not only that, it becomes difficult to form a uniform glue film on the surface of the fiber, and there is a concern that the glue film may be uneven and warp due to unevenness of the glue film, and the glue may fall off during the weaving process. The viscosity of the paste is 2
It is desirable to be 0 mPas or less, and if it exceeds 20 mPas, the penetrability of the glue between the polyester multifilaments is deteriorated and the cohesive force is deteriorated. Polyvinyl alcohol glue is used as a sizing agent for synthetic fibers, but the characteristics of this sizing agent are cheaper than acrylic sizing agents, and the strength and elongation of the sizing film are superior to other synthetic sizing agents. There is no problem, and it is widely used when setting it on a dry loom, but it is not suitable for the water jet loom as described in the above-mentioned fourth invention because it has no water resistance. Although many types of acrylic glue are commercially available, high-density fabric is a product that is relatively difficult to desizing and refining in dyeing plants, so a sizing agent with excellent desizing and refining properties should be selected. It is also important to do so.

Acrylic glue is used at the same time as a smoothing agent, softening agent,
It is necessary to add any one or more selected from antistatic agents and penetrants. Some acrylic pastes on the market by manufacturers include some leveling agents, softening agents, antistatic agents, etc., but the effect cannot be fully exerted by themselves. In other words, since the unevenness of the paste film surface is large and rough, adding a smoothing agent reduces the unevenness of the paste film surface, smoothes it and reduces the size of the paste, improves the open state of the warp, and reduces warp breakage. To do. The softening agent not only softens the glue film, but also softens the texture of the greige, and has the effect of facilitating warp bending for standards such as the high-density fabric of the present invention with a high weft threading density. Antistatic agents are essential for hydrophobic fibers such as synthetic fibers. Mixed glue, moisture content of glued yarn, warping condition,
The charge amount of synthetic fibers varies depending on the warping environment, weather conditions, etc. However, without an antistatic agent, static electricity is likely to occur in the warping and weaving processes, which may impair process passability. The penetrant has the effect of lowering the surface tension of the mixed paste, effectively penetrates the inside of the filament to the synthetic fibers of the present invention, which have a large number of relatively fine fineness, and coats and fixes each filament with the paste. Not only does this increase binding force, but it also reduces warp breakage as well as less sizing. When preparing the paste, a small amount of antiseptic agent, defoaming agent or the like may be added as necessary. However, if the additives such as a smoothing agent, a softening agent, an antistatic agent, a penetrating agent, a preservative, and an antifoaming agent are excessively added, the paste film becomes soft and warp breakage is induced during weaving, which is preferable. Absent.

It is desirable that the adhering rate of the warp yarns by sizing or sizing using the above-mentioned mixed sizing is 15% by weight or less. Acrylic glue,
It contains a smoothing agent, a softening agent, an antistatic agent, a penetrating agent, etc., and can improve passability in the warping and weaving process of the high-density woven fabric made of the synthetic fiber of the present invention and improve the quality of raw fabric. it can. However, when it exceeds 15% by weight, the size of the sizing is increased, warp breakage is induced, the flexibility of the sizing yarn is decreased, and the texture of the woven fabric becomes hard, and the weft driving density of the high-density woven fabric of the present invention is increased. There is a problem of insufficient input for high standards. Furthermore, the cost and economy of the mixed glue are not good. Considering the fluff binding, tying force, warp, and weavability in the weaving process of the sizing yarn, the preferred amount range of the sizing yarn is 4% by weight or more and 10% by weight or less. For sizing and sizing, a single sizing machine that excels in small lot production and a warping sizer that excels in mass production are used.
