TH18034A - "Extruded materials between films With a liquid-permeable fiber sheet " - Google Patents

Abstract

What is revealed in this invention is The layered material between the film and the fibers. Which film with a slit at Generally parallel Due to the condition of the process, several cycles are extruded into the support layer, such as non-woven sheets. When the film layer Slit and the support layer is pressed together, the composite material is left to shrink. By this method, the composite material will have the appearance of corrugated or compressed fibers with a wavy surface. The wavy surface also causes the slits to form multiple openings, which are generally perpendicular to the center plane of the film. In addition, because The wavy nature of the film surface, the resulting openings are located in, above and below the middle plane of the film layer. You can benefit in different ways. It is widely used among things, including coverings or body pads for manufacturing. Absorbent packaging for Take care of personal hygiene What is also revealed is the process for producing this composite material.
