Embodiment Construction

[0021] The embodiments of the present invention will be described in more detail below in conjunction with icons and component symbols, so that those skilled in the art can implement them after studying this specification.

[0022] refer to figure 1 , a schematic diagram of the bidirectional elastic breathable material according to the first embodiment of the present invention. like figure 1 As shown, the two-way elastic breathable material of the first embodiment of the present invention includes a one-way elastic cloth 10 and a two-way elastic film 20, and the upper surface of the two-way elastic film 20 is fully or partially attached to the lower surface of the one-way elastic cloth 10 On the surface, a multi-layer structure with two-way elasticity is formed. The above-mentioned partial lamination can have multiple implementations, to achieve local point-like lamination, grid-like lamination, strip-like lamination, etc. in a matrix arrangement, and figure 1 is a demonstr...

Abstract

The invention relates to a bidirectional elastic breathable material. The bidirectional elastic breathable material comprises a unidirectional elastic cloth and a bidirectional elastic film, wherein the unidirectional elastic cloth is provided with a plurality of penetrating breathable holes and has the latitudinal elongation, the bidirectional elastic film is made of a thermoplastic elastomer material and also provided with a plurality of penetrating breathable holes and has the appropriate elongation in both the latitudinal direction and the meridional direction, and the upper surface of thebidirectional elastic film is fully or partially attached to the lower surface of the unidirectional elastic cloth. In particular, the breathability of the bidirectional elastic film is 17-25 cc / secper square centimeter, and the overall breathability of bidirectional elastic material is 7-10 cc / sec per square centimeter. The bidirectional elastic breathable material has the advantages of bidirectional extension and breathability, and is suitable for being applied to closed-fit clothes or diapers, the comfortable sensation is improved, and stuffiness and moist are avoided.

Description

technical field [0001] The invention relates to a two-way elastic air-permeable material, in particular, at least one two-way elastic film is laminated with at least one one-way elastic cloth with latitudinal elongation, so as to achieve the characteristics of two-way strong resilience and high air permeability. Background technique [0002] When considering hygiene and safety, general hygiene products are usually disposable or disposable to avoid contamination by germs or harmful substances, such as masks, laundry-free pants, baby diapers or adult diapers. Because these products will be in contact with the skin for a period of time, the requirements for air permeability are relatively strict, so as to prevent discomfort or skin allergies, itching, and even rashes caused by stuffy heat or humidity. [0003] Due to the advantages of easy manufacturing, processing, good chemical resistance, durability and low cost, non-woven fabrics from plasticized materials have been widely ...
