V. Description of the invention (The exemption of the present invention is related to the elastic layer.) More specifically, the present invention is about an elastic layer including a non-woven layer formed of high-oriented component fibers. The present invention also relates to the use of this elastic layer. Examples of such disposable clothes include disposable underwear, disposable diapers including wearable (pull_〇n) # pieces and training pants, and disposable pants for menstrual use. 3. Elastic laminates have previously been used in a variety of disposable products, including sweat bands, bandages, body wraps, and disposable clothing including disposable diapers and incontinence devices. Here, " Elastic buildup " means two or more layers of elastically stretchable material that includes at least one layer of elastically stretchable single layer material. It is generally expected that these products are made by using appropriate elastic it pieces throughout the life of the product. The user's body and / or skin provides a good fit. &Quot; Zero-strain " stretch laminate is a type of elastic laminate that is preferred for use in such disposable products. For example, manufacturing " zero response The method of stretching the laminated network reveals the number of US patents issued to Weber et al.

434007, V. Description of the invention (2 states ^ Therefore, the elastic laminate is formed as a "zero strain" stretch laminate. Here, a "zero strain" stretch laminate is composed of at least two layers when it is substantially unstressed (&Quot; Zero Strain ") in a state where a layer of I material is fixed to each other along at least a portion of its co-extending surface; one of the layers includes an extensible and elastomeric type (that is, it will be substantially restored to its original value after the tensile force is released Unstressed dimensions), and the second layer is extensible (but not necessarily an elastomeric type), so that when stretched, the second layer will have at least some degree of permanent elongation, so that when a tensile force will be applied When released, it will not fully return to its original undeformed shape. Therefore, the resulting stretch laminate will be elastically stretchable at least until the initial stretch point in the direction of the initial stretch. As mentioned previously, this zero strain & quot The method of making the stretch laminate includes the step of subjecting the inelastic composite stretch laminate to mechanical stretching sufficient to permanently stretch the inelastic component. This step is a general elastic lamination process In addition, and it limits the materials used in the elastic laminate, for example, the elastomer-type materials and other composite materials used in the elastic laminate need to have sufficient physical strength or toughness, because their materials will be damaged by the process machinery For example, if the elastomeric material does not have sufficient strength or toughness, the elastomeric material tends to be easily torn by the stress applied to the elastomeric material during the mechanical stretching process during the manufacturing process and during the use of the product. Broken or torn. According to the foregoing description, there is a need for an elastic laminate that does not have such restrictions on the elastomeric materials used therein.

Description of the invention (3) A member of the Intellectual Property Bureau of the Ministry of Economic Affairs (Consumer Cooperation Du printed ype) "— a type of disposable clothing that has a system of fasteners that secures the disposable clothing to the waist area of the wearer. Generally, a tape system or a mechanical fastener system is used as this fastener system. Recently, it is preferred to use elastically stretchable ear panels for this type of disposable clothes, & Provides a better fit to the waist area of the wearer by working with the fastener system. Often referred to as " pants " or " wearable ", and the other type of disposable clothing has a fixed side And is commonly used by children who can walk and are usually training in the toilet. This type of wearable garment has ear-like molding, the edges of which are joined to form a leg opening and a waist opening. It also has a stretchable belt placed along at least one of the edges of the disposable clothing. ”These wearable clothing should fit the waist and legs of the wearer tightly, without sagging, or sagging from a position on the body. To accommodate body secretions. Examples of such wearable clothes are disclosed in, for example, U.S. Patent No. 5, m, 239 issued to Igaue et al., U.S. Patent No. 4,61,681 issued to Strohbeen et al., And 1993 WO09 / 1 " 7648 announced on May 16th, U.S. Patent No. 4,940,464 issued to van Gompel et al., U.S. Patent No. 5,246,433 issued to Hasse et al., And U.S. issued to Buell et al. Patent number 5,569,234. The good performance characteristics of these stretchable ear panels and belts are important for these types of disposable garments. More specifically, the elongation properties of the ear panel and the belt include elongation force, restoring force, retention force, and effective stretching (extension), which are important considerations in the performance of the fit of the wearable clothes. The elongation property provides the user and the wearer with the overall perceivable stretch when using it.

Invention description (33) The absorption / distribution layer 82 is better. The absorption / distribution layer 82 is provided to help reduce the tendency of the surface of the skin layer 24 to wet. The absorbent / distribution layer 82 preferably includes carded, resin-bonded high-layer nonwoven materials, such as, for example, purchased from Polymer Group, Inc. (Landisiville, NJ, USA) No. FT-6860, which is made of 6 dtex polyethylene terephthalate fibers and has a basis weight of about 43 g / m2. One of the preferred examples of the absorbent / distribution layer 82 and the absorbent / distribution core material 84 is disclosed in EP 0797968A1 (Kurt et al.) Published on October 1, 1997. The surface layer 24 is obedient, soft to the touch, and is suitable for the wearer's skin. Not irritating is preferred. 6 In addition, the surface layer 24 is liquid-permeable, which allows liquid (eg, urine) to penetrate easily through its thickness. The appropriate surface layer 24 can be made from a wide range of materials, such as woven and non-woven. Materials; polymeric materials such as perforated thermoplastic films, perforated plastic films, and wet > hydroformed thermoplastic films; porous foams: reticulated foams: reticulated thermoplastic films; and thermoplastic scrims. Suitable woven and non-woven materials may include natural fibers (e.g., wool or cotton fibers), synthetic fibers (e.g., polymeric fibers such as polyester, polypropylene, or polyethylene fibers), or a combination of natural and synthetic fibers. The skin layer 24 is made of a hydrophobic material so that the skin of the wearer is better isolated from the liquid passing through the skin layer 24 and contained in the absorbent core material 25 (i.e., preventing rewetting). If the surface layer 24 is made of a hydrophobic material, at least the upper surface of the surface layer 24 is treated to be hydrophilic so that the liquid can penetrate the surface layer more quickly. This eliminates the possibility that the body secretions will flow out of the surface layer 24 instead of being drawn through the surface layer 24 and absorbed by the absorbent core material 25. The surface layer 24 can pass the surface -36- this paper size applies the Chinese solid standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page) Binding-Staff of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the consumer cooperative 4 3 4007 ^ a? _______B7_____ V.

Another-fortunately, the surface layer 24 includes a perforated film. The perforated forming film is better for the surface layer 24, because it can pass through body secretions, but is non-absorbent, and has a reduced tendency to let the liquid pass back and moisturize the skin of the wearer. Therefore, the surface of the formed film that is in contact with the body is kept dry, so it is reduced by 37- This paper size applies to the Chinese National Standard (CNS) A4 $ 格 （2】 0 X 297 公 爱 ----- I ------ ^ I --- (Please read the note on the back before filling in this page) i.
