摘要： A method for the production of an elastic, air-permeable laminate film is disclosed, whereby material webs made of a fiber non-woven fabric are applied to both sides of an elastomer layer, and the multi-layered material subsequently runs through an ultrasound bonding station. The elastomer layer is melted to form point-shaped bonds at discrete locations by means of ultrasound, while maintaining the substance of the fiber non-woven fabric. An air-permeable structure is formed at the melted sites. According to the method, a melt film made of a thermoplastic elastomer is passed to a laminating unit and introduced, in the thermoplasticized state, between two material webs of fiber non-woven fabric that run into the laminating unit. The melted intermediate layer of the multi-layered material is cooled to solidification temperature, whereby a laminate with cover layers made of fiber non-woven fabric is produced. The laminate is subsequently passed to the ultrasound bonding station.

摘要： A method for manufacturing a novel air permeable composite film is disclosed. The air permeable composite film has a polymer layer with a top face and a bottom face and a sealing layer covering the top face. The polymer layer is first perforated by virtue of an impression process to form a plurality of tiny gaps in it for air permeation. Then the sealing layer is coated on the top face of the polymer layer to fill the gaps. The differential pressure between the top face and bottom face of the polymer layer enlarges the gaps and makes the gaps become air permeable.

摘要： A preparation of thermal contraction sleeve is disclosed. In this method, polyethylene fibers are elongated by 850%˜1,200% and are exposed to a radiation of 2.5˜3.5 Mrads, thus being cross-linked. The first surface of a fabric sheet, made of the polyethylene fibers, is exposed to a voltage of 20,000˜25,000 V while passing over a plurality of rollers, thus being modified at the first surface. A first matrix sheet, melt-extruded at a temperature of 300° C.˜380° C., is formed on the modified first surface of the fabric sheet, prior to an integration of the first matrix sheet with the modified surface of the fabric sheet. The integration is accomplished by a first elastic roller and a first cooling roller. The second surface of the fabric sheet is processed in the same manner as that described above. A second matrix sheet is layered on the modified second surface of the fabric sheet, thus forming a fabric-matrix layered body. The matrix sheets of the fabric-matrix layered body are exposed to a radiation of 2.5˜3.5 Mrads, thus being cross-linked.

摘要： A microporous membrane is described comprising at least two layers, wherein each layer is characterized by nodes interconnected by fibrils, the layers are bonded by means of plastic flow at temperatures below the melting point of either membrane material, and the pore architecture is formed in situ by an expansion process. A stratified microporous membrane is produced wherein the pore architecture of each layer may be discretely controlled.
