慮されているものは少なかった。Coating with a resin such as urethane is used. In all of these, water repellency was imparted only by finishing chemicals, and few of them took into consideration the two textures of the thread used in the base fabric.

いくという問題が発生する。However, recently there has been a demand for flood control products that have appropriate water pressure resistance and breathability, and accordingly, consideration has been given to the thread usage and density of the base fabric. These products are called super-connected wood processed products and are beginning to appear on the market, but the JIS
Even if the value of water repellency evaluated by the spray method of L-1092 is 100, if you spray water droplets onto these super-connected products and rub them with the palm of your hand, for example, the water droplets will fall onto the surface of the fabric. It often sticks. In actual wear, exercise is involved, so for example, both sleeves rub the torso, and when wearing pants, both legs rub the inner thighs of each other. Water droplets adhere to the fabric due to friction, which seriously affects its appearance, and the water repellency eventually deteriorates due to the effects of body temperature.

織物を製造する方法を提供しようとするものである。(c) Problems to be Solved by the Invention The present invention solves the above-mentioned problem of water droplets easily adhering to the surface of conventional water-repellent fabrics due to friction, etc., and has a continuous surface on which water droplets easily roll. It is an object of the present invention to provide a method for producing a new water-repellent fabric.

（ニ）問題点を解決するための手段及び作用本発明は、
単フィラメントの織度差が２デニール以上である太織度

性織物の製造方法である。(d) Means and action for solving the problems The present invention includes:
The total weave is 50 to 300 deniers, which is a mixture of a thick weave yarn and a fine weave yarn whose single filament weave difference is 2 deniers or more, and the number of single filaments is 1 to 5 or more of the latter. A woven fabric with a diagonal texture is woven using the synthetic long-fiber, long-fiber, mixed-woven, bulky textured yarn for the warp and weft, and a fluorine-based water repellent is applied to the woven fabric after scouring and processing. This is a method for producing a water-repellent fabric.

外力が加わっても水滴が付着することが無い撥水性織物
を得ることができる。That is, in the present invention, by weaving using a specific thread and a specific weaving structure as described above, and further adding a fluorine-based water repellent, a sufficient air layer is maintained within and between the threads of the fabric. When water droplets drip onto the surface of a fabric at °C, a sufficient air layer is formed between the surface and the water droplets, and together with the presence of the fluorine-based water repellent, the water droplets easily roll on the surface and cause friction. It is possible to obtain a water-repellent fabric that does not attract water droplets even when external forces such as the above are applied.

程度である。In the present invention, the surface on which water droplets easily roll refers to a surface on which 2 cc of water is gently dropped onto a flat sample to be measured mounted on a horizontal plate to form a single water drop, and then the flat plate is rolled at a constant speed. The surface is gently tilted and the angle of inclination to the horizontal plane of the flat plate at the point when the water droplet starts rolling is 8 degrees or less, preferably 6 degrees or less, and the coefficient of static friction tanθ of the water droplet is
In other words, it is 0.105 or less. A typical water-repellent product that has been simply treated with a reaming agent has a water repellency of about 12 to 20 degrees, and even products that are said to have super water repellency have a water repellency of about 8 to 12 degrees.

、小さな空気層を多数形成することができる。In the present invention, first, as the warp and weft, synthetic woven fiber long woven fiber different woven bulk textured yarn (hereinafter simply referred to as mixed woven yarn) is used.
In addition, the blended yarn is thick monofilament and II
The difference in weave from I fineness monofilament is 2 deniers or more,
In addition, it is necessary that the mixed weaving ratio of the thick weave yarn and the 851-meter yarn is at least 5 to 1 for the former in terms of the number of single filaments. When the weave difference is less than 2 deniers, the single filaments are likely to be aligned with each other within the yarn, the gaps between the single filaments are small, and the amount of air retained is small. Also, by blending finely woven yarns, it is possible to reduce the gaps between the woven fabrics and improve the water pressure resistance required at the same time for water repellent finishing. The blend ratio of thick weave yarn and II[I#lA yarn is
If the number of single filaments is 1 for the former and less than 5 for the latter,
When made into a woven fabric, there is less disturbance on the yarn surface, and fewer air layers are formed. Further, since the above-mentioned blended yarn is a bulky textured yarn, the filaments on the yarn surface are greatly disturbed and many small air layers can be formed.

気層が形成される織物が得られる。Next, in the present invention, in order to more effectively form an air layer between the fabric surface and the water droplets, the total weave of the blended yarn is extremely important, and the total weave is preferably 50 to 300 deniers. uses yarn of 100 to 150 deniers. When the total weave is less than 50 denier, the irregularities on the surface of the fabric, particularly when it is made into a diagonal texture, are small, and there are few air spaces formed between the fabric and the water droplets, and when rubbed in a manner that presses the water droplets, There is a drawback that water droplets tend to adhere to the surface of the fabric, and if it exceeds 300 denier, the unevenness of the fabric surface becomes too large, and the water droplets may instead get stuck between the unevenness, or the texture is rough, and the unevenness of the fabric surface becomes too large. It is unsuitable because water droplets can easily get into it. The total weave is preferably 10
By using threads of 0 to 150 deniers, diameter 2
A fabric is obtained in which an air layer is effectively formed between the surface and the normal-sized water droplets of ~8 dragons.

〜１６個程度あるものが最も良好な結果が得られる。In the present invention, the above-mentioned mixed yarn is used for both the warp and the weft to weave a diagonal texture, but if it is used only for either the warp or the weft, the purpose of the present invention cannot be fully achieved. I can't. In addition, by making the weave texture a diagonal texture, it is possible to maintain air layers between the textures, and when the weave is made into a plain texture, the surface has less unevenness and is flat compared to the diagonal texture. The amount of air between the water droplets and the fabric surface is small, which is insufficient to repel the water droplets, and the water droplets tend to adhere to the surface due to rubbing. Furthermore, among the oblique textures, 1/3 or 2/2 twill with clear oblique text, or variable textures with high French acid or oblique text are preferable, and it is especially desirable to have about 8 to 28 oblique text between IC11. is lO
The best results can be obtained with about 16 pieces.

ることは言うまでもない。The fabric obtained as described above is subjected to scouring and processing such as lyra, kusu, scouring and heat setting, dyeing as necessary, by conventional methods, and then a fluorine-based water repellent is applied, dried, and heat treated. administer. Here, in order to obtain a sufficient water repellent effect, it is preferable that no dyeing aid or the like remains on the fabric to which the fluorine-based water repellent is applied. It goes without saying that when applying a fluorine-based rainwater agent, antistatic agents, softeners, melamine resins, catalysts, penetrants, etc., which are commonly used for finishing fibers, can be used in combination as necessary.

When you look at this fabric with a magnifying glass, you can see that the single filaments are not lined up in an orderly manner, but are moderately disordered, because the yarn is a bulky textured yarn and a mixed yarn with different fineness. In addition, it was observed that the thick yarn and the fine yarn also maintained an appropriate space.
