New description: [Technical field of new type] This work is about a structure in which the laminate has a bidirectional elastic extension. [Prior Art] In the market of disposable consumer products, such as disposable diapers, baby trousers, and other disposable sanitary wares, there is a need to improve fit and comfort, and therefore, it is highly flexible. Highly elastic recovery rate and high gas permeability. The laminate is a product that meets this demand. It is also expected that the elastic laminate can be elastically stretched in both directions. Disposable personal care products and health care products are usually breathable and strong enough to handle normal use. Breathability refers to the extent to which it can pass through the body or moisture; while strength is related to tensile properties. In theory, although autumn can improve the elongation of the polymer film of each laminate separately, it must be a material with a better elongation, and (4) a shaft. Therefore, for a long time, elastic laminates having a strength of :::: strength and elastic elongation have been demanded for the manufacture of personal care sputum, health care products and the like. The production form (4) depends on the fiber structure of the cloth after the cloth is added. After the release of the tension in the autumn, the cloth material is naturally retracted into the #^曼 weaving cloth. Having a two-dimensional elastic extension and a two-dimensional elastic unidirectional elastic surface, and a two-dimensional elastic 3 M415053 extensible shell In order to make the laminate ι have a sexual extension after the product. However, the combined elastic film as the laminate-side surface will make the laminate feel uncomfortable when it is made into clothes or used. [New content] The purpose of this creation is to solve the problem of bidirectional flexibility. The non-woven fabric of the extended nature is combined on the non-woven side with the elastic 骐 which has the bidirectional elastic extension property. The layered composition having the bidirectional elastic extension property is made into a garment or a body σ# , , 5 After the touch is not good, the problem of uncomfortable use. ^乍的待' is an elastic film combined with two layers of elastic fiber web 2'. The elastic film is covered by two layers of elastic fiber mesh material, and the film is exposed to cause poor touch. The other feature of the creation of the float is to provide two layers of elastic fiber mesh material with unidirectional elastic shells. The two layers of elastic fiber mesh material are used to make two layers of elastic fiber mesh. The elastic extension direction of the material is perpendicular to each other, and the elastic film with two-way elastic extension constitutes a laminate, so that the fresh character has superior two-way elastic extension property. Hey. Based on the technical means of this creation, the two-way elastic film is divided on two sides, and the D σ first-early elastic fiber mesh layer material and the second unidirectional elastic fiber mesh layer are used and the first-single The elastic extension direction of the elastic fiber mesh layer material is perpendicular to the elastic extension direction of the elastic fiber mesh layer material, and the first unidirectional elastic fiber 4 M415053 mesh layer material and the second unidirectional elastic fiber mesh layer material The modulus of elasticity is lower than that of the biaxial elastic conjugate filament; the laminate structured by the foregoing structure has a bidirectional elastic 'extension property. The elastic film 疋-type elastic high-molecular polymer can be provided with a venting hole or a venting hole. When the vent hole is provided, the unidirectional elastic fiber layer material is combined with the unidirectional elastic fiber _ layer material to have a gas permeable penetration. s, when made into clothing, it is more comfortable to wear. [Embodiment] The following is a more detailed explanation of the implementation of this creation with the drawings and component symbols. The two-dimensionally extended elastic laminate of the present invention does not have a first unidirectional elastic fiber web material u, a second unidirectional elastic fiber web tear 12 and a bidirectional elastic film 13; The first unidirectional elastic fiber mesh layer material can be made into an elastic woven fabric of the United States. Wherein, the first unidirectional elastic fiber web material η has a one-way job delay in the X direction #((四)二_示) ==:r一•第干干) m phase has elastic extension (such as the fourth Figure: This creation combines the first unidirectional hybrid web layer material 12 into a two-way elastic wide elastic layer (4) such as =; _ mail to form a U Wuqiu), of which, the first-single fiber 5 The elastic extension direction of the mesh material U is perpendicular to the elastic extension of the grapefruit a + 士平丨J Ping H隹 mesh material j 2 — the direction of the extension, and the first unidirectional elastic fiber layer material U gold first. The first early coefficient of the elastic fiber mesh material 丨2. In addition, the elasticity of the two-way elastic film 13 is two-way elastic, and the single-L--- unidirectional elastic fiber mesh material 1! 〆, brother-early elastic The fiber mesh face is estimated to be different from the β-injection 2, and the plurality of vent holes (3) can be set in advance to make the combined laminate 丨 have a gas permeable property. Gu Ba = such as the elastic film 13 is an elastic polymer, The elastic core contained therein should account for the optimum ratio of the two-way elastic laminate 1 to be larger than the chest weight: the knife ratio, the first one The elastic fiber web material or the second unidirectional elastic fiber cloth: the combination of the Γ412 and the bidirectional elastic film 13 can be applied on the mating surfaces of the two: ::In: Adhesive, or the combination of the two is super Acoustic bonding, heating and pressure bonding, 4 °, electronic wire bonding, electrostatic technology, or chemical touch bonding; from, wipe out casting film, foam film formation, or direct lamination method 2 tweezers The polymer is coated on the surface of the first unidirectional elastic fiber web layer or the second unidirectional elastic fiber mesh layer material 12.

The non-woven fabrics may be early polymer, bicomponent or blended fibers. / & the elastic film 13 may be made of a variety of elastic polymers, but the material must first be made The air and the material are infiltrated. In the implementation of the project, use 0. 02 6 M415053 to 〇. 〇 3mm thickness bomb Polyurethane film. Two-way elastic 1" film 13 can also be composed of a multilayer film. Other elastic materials can also be used as a unidirectional elastic film, such as a single layer of elastomer or foamed plastic layer, but these The film must be composed of a material that is impermeable to both liquid and air. The elastic film 13 can also be composed of a film of another highly elastic compound, such as a block copolymer, which is a long segment (block) of the same monomer unit (4). It is formed by the long and conjugated bonds of different types of units (B). The blocks can be connected in various ways, for example, they are incorporated into the I and ΑΒΑ underdose structure. Usually the compound exhibits a very good elastic recovery. When force or field is dialed out in a single layer, it stretches more than (10) but it is still not easy to lose the bullets. In a particular embodiment, the elastomeric material can comprise a high performance elastomeric material such as styrene/isoprene/styrene, styrene/isoprene/butadiene or stupid ethylene/ethylene-butene/benzene Ethylene (SIS, Deletion or s_ or Κγ_ Chemical Company's KratonTM Elastic Resin, all of which are elastic copolymers. The special form of the post-copolymer has a significant effect on the suppository of the main body. Lu as a two-way elastic film The useful miscellaneous composition of 13 may comprise an ethylene copolymer such as ethylene acetate, acetonitrile/propylene copolymer elastomer or ethylene/acrylonitrile/dicarbide (10) hybrid. This creation may also be single-sensitive. The elastic film is made of a mixture of the materials or a mixture of the black and white materials and other modified elastic or non-elastic materials. The above is only the use of the liberation of the creation of the original, not an attempt to create this Any form of restriction is that any modification or alteration of the creation made in the spirit of the same invention shall be included in the scope of this Creative Intent 7 M415053.
