Description
本発明は、和紙調の外観を有しかつ引裂き強度の強い複合繊維構造体および該複合繊維構造体を用いてなる繊維製品に関するものである。 The present invention relates to a composite fiber structure having a Japanese paper-like appearance and strong tear strength, and a fiber product using the composite fiber structure.
日本古来の和紙はその独特の外観や通気性等の機能性を有しており、室内の装飾品の材料として広く使用されている。しかしながら、和紙は天然材料であるため、引裂き強度が小さい、耐水性に劣る、燃焼しやすいなどいった欠点を有している。 Japanese traditional Japanese paper has its unique appearance and air permeability, and is widely used as a material for interior decorations. However, since Japanese paper is a natural material, it has drawbacks such as low tear strength, poor water resistance, and easy combustion.
このため近年では、ポリエステル系フィラメントを用いて織編物を製編織し障子戸とすること（例えば、特許文献１参照）や、和紙や不織布にコーテングを施して壁紙などとすること（例えば、特許文献１参照）が提案されている。しかしながら、ポリエステル系フィラメントを用いた織編物では、和紙調の外観が得られないという問題があった。一方、不織布からなるものでは、引裂き強度が小さいという問題があった。
他方、特許文献３では、織物に短繊維からなるウエブが水流絡合により複合一体化された、高級感のある複合繊維構造体が提案されている。
For this reason, in recent years, woven and knitted fabrics are knitted and woven using polyester filaments to form shoji doors (for example, see Patent Document 1), and Japanese paper or nonwoven fabric is coated to make wallpaper (for example, Patent Documents). 1) has been proposed. However, a woven or knitted fabric using polyester filaments has a problem that a Japanese paper-like appearance cannot be obtained. On the other hand, the nonwoven fabric has a problem that the tear strength is small.
On the other hand, Patent Document 3 proposes a high-grade composite fiber structure in which a web made of short fibers is combined and integrated by hydroentanglement with a woven fabric.
本発明は上記の背景に鑑みなされたものであり、その目的は、和紙調の外観を有しかつ引裂き強度の強い複合繊維構造体および該複合繊維構造体を用いてなる繊維製品を提供することにある。 The present invention has been made in view of the above-described background, and an object thereof is to provide a composite fiber structure having a Japanese paper-like appearance and strong tear strength, and a fiber product using the composite fiber structure.

The inventors have found that a strong composite fiber structure can be obtained, and have further intensively studied to arrive at the present invention.

まず、織物Ａを構成する、繊維形成性熱可塑性ポリマーからなるモノフィラメントの繊度は、５〜６０ｄｔｅｘである必要がある。該繊度が、５ｄｔｅｘよりも小さいと引裂き強度が低下するため好ましくない。逆に、該繊度が６０ｄｔｅｘよりも大きいと後記のメッシュ数で織成することが困難となるだけでなく、和紙調の外観が得られ難く好ましくない。なお、かかるモノフィラメントの繊度は、経糸と緯糸とで、同繊度であってもよいし、異繊度であってもよい。
Hereinafter, embodiments of the present invention will be described in detail.
First, the fineness of the monofilament which consists of a fiber-forming thermoplastic polymer which comprises the fabric A needs to be 5-60 dtex. If the fineness is less than 5 dtex, the tear strength is lowered, which is not preferable. On the contrary, when the fineness is larger than 60 dtex, it is not only difficult to weave with the number of meshes described later, but it is difficult to obtain a Japanese paper-like appearance. The fineness of the monofilament may be the same or different in warp and weft.

By employing polyester as the fiber-forming thermoplastic polymer, the fabric A can be dyed, the color of the fabric A can be freely expressed, and a printed pattern can be used. Furthermore, cleaning when dirty becomes easy.
