Abstract

PROBLEM TO BE SOLVED: To obtain a production process for elastic nonwoven fabric which is simple and causes no wrinkle on the surface of the product. SOLUTION: Molten elastic rubber is printed on nonwoven fabric extended in the running direction in a variety of shapes, for example, stripes parallel to the face of the nonwoven fabric, cross network or randomly irregular shape and the nonwoven fabric is soaked with the molten elastic rubber. Then, the molten rubber is coagulated to make the nonwoven fabric elastically stretchable in a single direction.

【発明の属する技術分野】本発明は、一種の弾性不織布の製造方法に関し、特に製造した不織布に皺を発生させず、且つ簡単に製造できる方法に関する。 The present invention relates to relates to a process for the preparation of a kind of elastic nonwoven, in particular without generating wrinkles in the manufacture nonwoven relates to a method and can be easily manufactured.

【0002】 [0002]

【従来の技術】不織布は非弾性不織布と弾性不織布の二種に分けられる。 BACKGROUND ART nonwoven is divided into two inelastic nonwoven fabric and an elastic nonwoven fabric. 弾性不織布の製造方法には、不織布編織の工程中に、繊維中にすでに引き伸ばされた弾性糸を挟み込ませたり、二層の不織布中に加熱溶融により製造したゴムフィルム或いはゴムネットを挟み込ませる方法があり、以て織り上げ後の不織布に伸縮可能な弾性を付与していた。 The method for producing elastic nonwoven, during the process of weaving nonwoven knitted, or to sandwiched the elastic yarn was already stretched in the fiber, a method in which sandwiched the rubber film or rubber net produced by heating and melting the nonwoven fabric of two layers There had been granted stretchable elastic nonwoven fabric after weaving Te following. しかし、上述の2種類の方法で製造された不織布は、弾性糸或いはゴムフィルム(ネット)の回復収縮作用により布面に皺を形成し、製品の価値に大きな影響を及ぼした。 However, nonwoven fabric produced by the two methods described above, the wrinkles formed on the fabric surface due to the recovery contracting action of the elastic yarn or rubber film (net), had a significant impact on the value of the product.

【0003】もう一種の弾性不織布の製造方法は、台湾特許願第78110066号のようなもので、それは、 The preparation method of another one of the elastic nonwoven fabric, like a Taiwanese Patent Application No. 78110066, it is,
ランダム共重合により、少なくとも二つのエチレン芳香族化合物を含む重合体段と、少なくとも二つの共役ジエン化合物を有する重合体段を含み、且つ少なくとも一つの重合体段が重合体連鎖の末端に配置し、また全体の平均分子量が30000〜65000の範囲内であり、ジエン芳香物の含有量が15〜40重量%の範囲内にある、ランダム共重合体を製造し、次に、該ランダム共重合体を酸化して、酸化ランダム共重合体を得て、紡績し、この紡績プロセスで得られた繊維群を捕集面上に集積させ、繊維ネットを形成するものであった。 By random copolymerization, a polymer stage comprising at least two ethylenic aromatic compound, at least comprises a polymer stages having two conjugated diene compound, and at least one polymer stage is arranged at the end of the polymer chains, average molecular weight of the addition is in the range of 30,000 to 65,000, the content of diene fragrance is in the range of 15 to 40 wt%, to prepare a random copolymer, then the random copolymer oxidized to to yield oxide random copolymer, spun, by integrating the fiber group obtained in this spinning process on a collecting surface, it was to form a fiber net.

【0004】またさらにもう一種の弾性不織布の製造方法は、台湾特許願第78110066号のようなもので、それは、以下のA〜Dの製造ステップを包括するものであった。 [0004] Further manufacturing method of another type of elastic nonwoven fabric, like a Taiwan patent application No. 78110066, which was intended to cover the following manufacturing steps to D. 即ち、A. In other words, A. 機械の方向に対し斜紋状に移動する支承表面に、少なくとも一つの熱可塑性の人造短繊維メッシュを形成並びに集合させ、B. The bearing surface to move relative to the direction of the machine obliquely striated shape, to form and set at least one thermoplastic synthetic staple fiber mesh, B. 低密度粘合模様を選び、形成し集合してなしたメッシュを軽く粘合させ表層成分と成し、C. Select low density Nebago pattern, form the formed aggregated engaged lightly tacky the mesh without and surface components, C. 軽く粘合させて成した表層成分の内表面に、少なくとも一層の、人造短繊維を含むメッシュを置き、なお、該表層成分は、一般的には機械方向と相対し横向き方向を呈するよう配列し、D. On the inner surface of the lightly engaged viscosity and surface components form, of at least one layer, placing a mesh comprising a synthetic short fibers, Note that the surface layer components is generally arranged to exhibit a machine direction relative to the horizontally-disposed , D. 実質上の粘合密度が該表層成分よりも高い粘合物を、横向きに置いた人造短繊維に粘合させ、以て底層成分を成して、不織布を得る。 The substantially higher Nebago were also Nebago density than said surface layer components, sideways artificial short fibers engaged viscosity placed, forms a bottom layer components Te than to obtain a nonwoven.

【0005】上述の後の二つの弾性不織布の製造方法は、製造プロセスが比較的複雑であり、製造コストが比較的高い。 The preparation method of the two elastic nonwoven after the above, the manufacturing process is relatively complicated, relatively high production costs. このため、製造が比較的簡易であり、且つ製品の布面に皺が発生しない、弾性不織布の製造方法が求められていた。 Therefore, manufacturing is relatively simple, and no wrinkles are generated in the fabric surface of the product, the production method of the elastic nonwoven has been demanded.
