以下、図１〜図６に基づいて、この発明の典型的な実施の形態について、説明する。この実施の形態にかかる生地１は、使い捨てのおむつ、使い捨ての下着、使い捨ての被服などの使い捨て衣料の主要材料として利用されるものである。 Hereinafter, typical embodiments of the present invention will be described with reference to FIGS. The fabric 1 according to this embodiment is used as a main material for disposable clothing such as disposable diapers, disposable underwear, and disposable clothing.
なお、本明細書中において「使い捨て衣料用生地１」とは、布帛等の複雑な縫製を施した縫製品以外の、不織布等の素材等を用いて簡易に製造した衣類であり、１回の使用で廃棄するものに限らず、短期間の使用や数回の洗濯に耐えうるものも含む。 In the present specification, the “disposable clothing fabric 1” is a garment that is simply manufactured using a material such as a non-woven fabric other than a sewing product subjected to complicated sewing such as a fabric. Not only those that are discarded after use, but also those that can withstand short-term use and several washes.
かかる生地１は、積層シート２と、弾性部材３とを含んで構成される。積層シート２は、第一生地層２ａと第二生地層２ｂとを有する。弾性部材３は、第一生地層２ａと第二生地層２ｂ間にあって接着によりこれらと一体化されて前記積層シート２に伸縮性を付与するようになっている。 The fabric 1 includes a laminated sheet 2 and an elastic member 3. The laminated sheet 2 has a first fabric layer 2a and a second fabric layer 2b. The elastic member 3 is located between the first fabric layer 2a and the second fabric layer 2b and is integrated with them by adhesion to give stretchability to the laminated sheet 2.
典型的には、第一生地層２ａを構成するシートと、第二生地層２ｂを構成するシートとを、間に張力を加えて引き延ばした状態の弾性部材３を介在させた状態で搬送させると共に、搬送途中で三者を接着一体化させ、この後、前記張力の付加を止めることで、伸縮性を備えた積層シート２を得ることができる。すなわち、引き延ばされた状態で第一生地層２ａを構成するシート及び第二生地層２ｂを構成するシートと一体化された弾性部材３が弾性復帰して縮むことで、第一生地層２ａを構成するシート及び第二生地層２ｂを構成するシートには後述の複数の凹凸付形４が形成されると共に、前記積層シート２には伸縮性が付与される。 Typically, while conveying the sheet | seat which comprises the 1st fabric layer 2a, and the sheet | seat which comprises the 2nd fabric layer 2b in the state which interposed the elastic member 3 of the state which extended and added tension | tensile_strength, The laminated sheet 2 having stretchability can be obtained by bonding and integrating the three in the middle of conveyance and then stopping the application of the tension. That is, when the elastic member 3 integrated with the sheet constituting the first fabric layer 2a and the sheet constituting the second fabric layer 2b in the stretched state is elastically restored and contracts, the first fabric layer 2a The sheet constituting the sheet and the sheet constituting the second fabric layer 2b are formed with a plurality of uneven shapes 4 which will be described later, and the laminated sheet 2 is provided with stretchability.
図示の例では、前記生地１は、このように構成される積層シート２単体から、構成されている。図示は省略するが、前記生地１は、前記のように構成される積層シート２の二枚以上をさらに積層させて構成しても構わない。また、前記生地１は、前記積層シート２の一枚又は二枚以上と、単純なシートの一枚又は二枚以上とを、積層させて構成しても構わない。 In the example shown in the drawing, the fabric 1 is composed of a single laminated sheet 2 configured in this way. Although not shown, the dough 1 may be configured by further laminating two or more laminated sheets 2 configured as described above. Further, the dough 1 may be configured by laminating one or more of the laminated sheets 2 and one or more of simple sheets.
前記第一生地層２ａ及び前記第二生地層２ｂは、使い捨て衣料の材料としての観点から、不織布又は紙から構成することが好ましい。特に、不織布は、繊維をそのままシート状にできるので、布のように織る・編むといったプロセスがない。この結果、早く大量に生産することができ、価格的にも安価で安定しているため、使い捨て生地として良好であるため、前記第一生地層２ａ及び前記第二生地層２ｂは不織布から構成することがより好ましい。以下の説明から、第一生地層２ａを「第一不織布２ａ」、第二生地層２ｂを「第二不織布２ｂ」と呼ぶ。不織布は、繊維を縦と横に織って作られる布帛以外の布を意味する。繊維には、天然繊維（植物繊維（セルロース高分子）、動物繊維（タンパク質高分子）など）のほか、精製繊維（リヨセル、テンセル等）、レーヨン、ビスコースレーション等の再生繊維、アセテート等の半合成繊維、ナイロン等の合成繊維、などの化学繊維が全て含まれ、適用用途に応じて適宜選択される。また不織布に用いる繊維は、１種単独で使用されていてもよく、２種以上が併用されていてもよい。かかる不織布としては、エアスルー不織布、スパンボンド不織布、メルトブローン不織布、スパンボンドとメルトブローンを積層した不織布、スパンレース不織布、カード法によるヒートロール（ポイントボンド）不織布、レジンボンド不織布、エアレイド不織布、ニードルパンチ不織布などを用いることができる。また、一方の不織布に離水性を持たせ、他方の不織布に吸水性を持たせて積層シート２を形成して、Ｔシャツや下着の生地に適用してもよい。 The first fabric layer 2a and the second fabric layer 2b are preferably composed of a nonwoven fabric or paper from the viewpoint of a material for disposable clothing. In particular, non-woven fabrics do not have the process of weaving and knitting like cloth because the fibers can be made into sheets as they are. As a result, it can be produced quickly and in large quantities, and since it is inexpensive and stable, it is good as a disposable fabric. Therefore, the first fabric layer 2a and the second fabric layer 2b are made of nonwoven fabric. It is more preferable. From the following description, the first fabric layer 2a is referred to as "first nonwoven fabric 2a", and the second fabric layer 2b is referred to as "second nonwoven fabric 2b". Non-woven fabric means a fabric other than a fabric made by weaving fibers vertically and horizontally. Fibers include natural fibers (plant fibers (cellulose polymers), animal fibers (protein polymers), etc.), refined fibers (lyocell, tencel, etc.), regenerated fibers such as rayon and viscose, and half of acetate, etc. Chemical fibers such as synthetic fibers and synthetic fibers such as nylon are all included and are appropriately selected according to the application. Moreover, the fiber used for a nonwoven fabric may be used individually by 1 type, and 2 or more types may be used together. Such nonwoven fabrics include air-through nonwoven fabric, spunbond nonwoven fabric, meltblown nonwoven fabric, nonwoven fabric laminated with spunbond and meltblown, spunlace nonwoven fabric, heat roll (point bond) nonwoven fabric by card method, resin bond nonwoven fabric, airlaid nonwoven fabric, needle punched nonwoven fabric, etc. Can be used. Alternatively, the laminated sheet 2 may be formed by imparting water separation to one non-woven fabric and water-absorbing the other non-woven fabric, and may be applied to a T-shirt or underwear fabric.
また、図示の例では、弾性部材３は複数であり、それぞれ長さを備え、隣り合う弾性部材３との間に所定の間隔を開けて、並列配置されている。すなわち、図示の例では、前記弾性部材３は、それぞれ、弾性糸条３ａから構成されている。なお、弾性部材３は、異なる収縮率のものを配置して、図６に示すように、後に述べる凹凸付形４、４…の形成に変化を持たせてもよい。また、図示は省略するが、かかる弾性部材３としては、網状のものを用いても構わない。また、かかる弾性部材３としては、通気穴や切り込みを複数備えたシート状のものを用いても構わない。前記弾性部材３は、ウレタン、シリコン等をベースとしたゴム、その他の合成材料からなるゴム、天然ゴム、その他の弾性素材から構成することができる。 In the illustrated example, there are a plurality of elastic members 3, each of which has a length, and is arranged in parallel with a predetermined interval between adjacent elastic members 3. That is, in the illustrated example, each of the elastic members 3 is composed of an elastic yarn 3a. In addition, the elastic member 3 may have a different shrinkage rate, and as shown in FIG. 6, the formation of the concavo-convex shapes 4, 4. Although not shown, the elastic member 3 may be a net-like member. Moreover, as this elastic member 3, you may use the sheet-like thing provided with multiple ventilation holes and notches. The elastic member 3 can be made of rubber based on urethane, silicon, etc., rubber made of other synthetic materials, natural rubber, or other elastic materials.
前記接着は、ホットメルト系接着剤、有機溶剤系接着剤又は水溶性接着剤によりなすことが好ましい。さらに、前記接着は、ホットメルト系接着剤によりなすことがより好ましい。ホットメルト系接着剤としては、公知の接着剤、例えば、ＥＶＡ（エチレン酢酸ビニル共重合体）系、ＰＯ（ポリオレフィン）系、ＰＡ（ポリアミド）系、ＳＲ（合成ゴム）系、ＡＣＲ（アクリル）系、 ＰＵＲ（ポリウレタン・湿気硬化型）系等、がいずれも好適に用いられる。これらは、１種単独で使用してもよく、２種以上が併用されてもよい。また、前記接着は、塗布を積層シート２前面に行うと、通気性・生地１の柔軟性を悪くするとともに、弾性部材３の伸縮性を阻害するこのため、接着は、前記第一不織布２ａ、前記第二不織布２ｂ及び前記弾性部材３の少なくとも一つに対し、連続塗布、部分塗布、スパイラル塗布、波状塗布、間欠塗布、ストライプ塗布、千鳥塗布、ブロック塗布またはコーターによって塗布することが好ましい。 The adhesion is preferably performed by a hot melt adhesive, an organic solvent adhesive, or a water-soluble adhesive. Furthermore, it is more preferable that the adhesion is made with a hot melt adhesive. Examples of the hot melt adhesive include known adhesives such as EVA (ethylene vinyl acetate copolymer), PO (polyolefin), PA (polyamide), SR (synthetic rubber), and ACR (acrylic). , PUR (polyurethane / moisture-curing type) and the like are all preferably used. These may be used alone or in combination of two or more. In addition, when the application is performed on the front surface of the laminated sheet 2, the air permeability and the flexibility of the fabric 1 are deteriorated, and the elasticity of the elastic member 3 is hindered. It is preferable to apply to at least one of the second nonwoven fabric 2b and the elastic member 3 by continuous coating, partial coating, spiral coating, wave coating, intermittent coating, stripe coating, staggered coating, block coating, or coater.

The shapes 4, 4... Are formed with a predetermined thickness so that the average light shielding rate of the laminated sheet 2 is 75% or more at the positions where the plurality of uneven shapes 4, 4,. Specifically, at least a part of the layer sheet 2 here refers to a part of the laminated sheet 2 corresponding to a part that the user wants to hide. Such a light shielding rate is measured in a state where the surface of the laminated sheet 2 is not dyed or printed. Moreover, this light-shielding rate is determined by measuring at least five or more of the uneven shapes 4, 4... Formed on the laminated sheet 2 and determining the average value.
図示の例では、複数の弾性部材３、３…はそれぞれ弾性糸条３ａとなっていると共に、各弾性糸条３ａはそれぞれ他の弾性糸条３ａと実質的に平行をなすように配されている。図示の例では、隣り合う弾性糸条３ａ間に、この隣り合う弾性糸条３ａ間に亘るように凹凸付形４の凹部４ａと凸部４ｂとが交互に形成された態様となっている。積層シート２の一面側において凹凸付形４の凹部４ａとなっている箇所は、積層シート２の他面側において凹凸付形４の凸部４ｂとなっている。 In the illustrated example, each of the plurality of elastic members 3, 3... Is an elastic yarn 3a, and each elastic yarn 3a is arranged so as to be substantially parallel to the other elastic yarn 3a. Yes. In the example of illustration, it becomes the aspect by which the recessed part 4a and the convex part 4b of the uneven | corrugated shaped 4 were formed alternately between adjacent elastic yarns 3a so that this adjacent elastic yarn 3a might be covered. The part which becomes the recessed part 4a of the uneven | corrugated shaped 4 in the one surface side of the lamination sheet 2 becomes the convex part 4b of the uneven | corrugated shaped 4 in the other surface side of the laminated sheet 2. FIG.

More specifically, the pressing means preferably includes an embossing roll. When doing in this way, the said uneven | corrugated shape formed in connection with removing the said addition of the tension | tensile_strength after three-part adhesion integration of said 1st nonwoven fabric 2a, said 2nd nonwoven fabric 2b, and said elastic member 3 4 can be applied to the nonwoven fabric with wrinkles or irregularities that can be easily formed in a manner that is substantially continuous in the direction y that intersects the expansion / contraction direction x of the elastic member 3. Accordingly, the fabric 1 can be provided with the plurality of uneven shapes 4 as regularly as possible. Specifically, such an embossing roll has a roll peripheral surface provided with a plurality of ridges and grooves alternately oriented along the rotation axis of the roll in the roll rotation direction, or a roll rotation axis on the roll peripheral surface. The thing provided with two or more fine dents which make the shape of a long long hole in a direction, the thing which formed the grain and the satin, etc. can be used. Further, the pressing means may be composed of a pair of embossing rolls, or may be composed of an embossing roll and a flat roll that receives the embossing roll. Furthermore, more uneven shapes 4, 4,... Can be formed by embossing one of the first nonwoven fabric 2a and the second nonwoven fabric 2b or individually.
前記積層シート２表面には、必要に応じて、染料、顔料を用いて染色・塗装したり、インクジェット方式やフレキソ印刷等により文字や画像を出力したりしてもよい。 If necessary, the surface of the laminated sheet 2 may be dyed and painted with a dye or a pigment, or may output characters or images by an ink jet method or flexographic printing.
