First, the fabric of the present invention is composed of fibers A having no water repellency and fibers B having water repellency. However, “fibers having no water repellency” in the present invention are fibers having a contact angle of less than 120 degrees, while “fibers having water repellency” are fibers having a contact angle of 120 degrees or more. In addition, a contact angle shall measure the contact angle of a fiber and a water droplet by (theta) / 2 method when 500 pl distilled water is dripped on the single yarn surface of a fiber using distilled water.
ここで、撥水性のない繊維Ａは、本発明において吸水性に寄与する繊維であり、ポリエステル繊維、ナイロン繊維、木綿やウールなどの天然繊維など特に限定されないが、ポリエステル繊維であることが好ましい。 Here, the fiber A having no water repellency is a fiber contributing to water absorption in the present invention, and is not particularly limited, such as polyester fiber, nylon fiber, natural fiber such as cotton or wool, but is preferably a polyester fiber.

When the weight ratio of the fiber A is larger than the above range, the water repellency of the fabric may be lowered, which is not preferable. On the contrary, if the weight ratio of the fiber B is smaller than the above range, the water repellency of the fabric may be lowered, which is not preferable.
本発明のしみ防止布帛において、布帛組織としては特に限定されない。例えば、よこ編組織としては、平編、ゴム編、両面編、パール編、タック編、浮き編、片畔編、レース編、添え毛編、片側結接、ニットミス、リバーシブル天竺等が例示される。また、たて編組織としては、裏挿入、シングルデンビー編、シングルアトラス編、ダブルコード編、ハーフ編、ハーフベース編、サテン編、ハーフトリコット編、裏毛編、ジャガード編等などが例示される。また、織物組織としては、平織、綾織、朱子織等の三原組織、変化組織、たて二重織、よこ二重織等の片二重組織、たてビロードなどが例示される。さらには、不織布であってもよい。もちろんこれらに限定されない。層数も単層でもよいし、２層以上の多層でもよい。 In the stain preventing fabric of the present invention, the fabric structure is not particularly limited.

Further, the fabric may be appropriately subjected to post-processing such as normal dyeing processing, weight reduction processing, raising processing, calendering processing, embossing processing, heat storage processing, water absorption processing, and antibacterial processing. Especially, it is preferable to perform water absorption processing in order to obtain excellent water absorption. A preferred example of a method for performing such a water-absorbing process is that the cloth is treated with a hydrophilizing agent such as PEG diacrylate and derivatives thereof or a polyethylene terephthalate-polyethylene glycol copolymer during dyeing.
かくして得られた布帛において、撥水性のない繊維Ａが水分を吸収すると同時に、撥水性のある繊維Ｂが水分をはじく効果を奏し、これらの相乗作用により、吸水性と撥水性とを兼ね備え、汗じみなどのしみを防止する効果を有し、さらにはこれらの洗濯耐久性にも優れる。 In the fabric thus obtained, the fiber A having no water repellency absorbs moisture, and at the same time, the fiber B having water repellency has an effect of repelling moisture. Due to the synergistic action, the fiber A has both water absorption and water repellency. It has the effect of preventing stains and the like, and is also excellent in washing durability.

When the basis weight is larger than 300 g / m 2, the weight of the fabric increases, and the wearing comfort of the fabric may be impaired. The thickness of the fabric is preferably 3.0 mm or less (more preferably 0.35 to 0.65 mm).

ここで、前記繊維Ｂが露出した表面（前記合成繊維Ｂが布帛の両面に露出している場合は、より多く前記繊維Ｂが露出する表面）を外気側に用い、一方、前記繊維Ａが露出した表面（前記合成繊維Ａが布帛の両面に露出している場合は、より多く前記繊維Ａが露出する表面）を内側（肌側）に用いると、内側表面において汗などの水分が速やかに吸収され、かつ外側表面に浸透しにくく優れたしみ防止効果が得られる。
なお、繊維製品に応じて、前記繊維Ｂが露出した表面と前記繊維Ａが露出した表面との表裏を適宜変更して、汗、雨水、飲料などのしみを防止してもよい。
Here, the surface on which the fibers B are exposed (the surface on which more fibers B are exposed when the synthetic fibers B are exposed on both sides of the fabric) is used on the outside air side, while the fibers A are exposed. When the surface (the surface on which more fibers A are exposed when the synthetic fiber A is exposed on both sides of the fabric) is used on the inner side (skin side), moisture such as sweat is quickly absorbed on the inner surface. In addition, it is difficult to permeate the outer surface, and an excellent stain prevention effect is obtained.
Depending on the textile product, the front and back of the surface where the fiber B is exposed and the surface where the fiber A is exposed may be appropriately changed to prevent stains such as sweat, rainwater, and beverages.

丸編２８Ｇダブル機を使用して、糸種１としてセミダルポリエチレンテレフタレートマルチフィラメント仮撚捲縮加工糸８４ｄｔｅｘ／７２ｆｉｌ（繊維Ａ）、糸種２として実施例１と同じシリコーン系撥水剤共重合型撥水セミダルポリエチレンテレフタレートマルチフィラメント仮撚捲縮加工糸８４ｄｔｅｘ／３６ｆｉｌ（繊維Ｂ）を用いて、図６に示す組織図の編地を得た。
次いで、該編地を染色工程で親水化剤（ポリエチレンテレフタレート−ポリエチレングリコール共重合体）と同浴処理を行うことにより、該編地に吸水性を付与した。得られた編地において、吸水性に優れるものの、ウエアにした時の外気側面の汗じみが目立つものであった。
[Comparative Example 1]
Using a circular knitting 28G double machine, as a yarn type 1, semidela polyethylene terephthalate multifilament false twist crimped yarn 84 dtex / 72 fil (fiber A), and as a yarn type 2, the same silicone water repellent copolymer as in Example 1 A knitted fabric having a structure chart shown in FIG. 6 was obtained using a type water-repellent semi-dal polyethylene terephthalate multifilament false twist crimped yarn 84 dtex / 36 fil (fiber B).
Next, the knitted fabric was subjected to the same bath treatment with a hydrophilizing agent (polyethylene terephthalate-polyethylene glycol copolymer) in the dyeing step, thereby imparting water absorbency to the knitted fabric. In the obtained knitted fabric, although it was excellent in water absorption, the sweat on the outside air side when it was worn was conspicuous.
