Easy-to-composite multi-layer composite mask and manufacturing method thereof

Abstract

The invention relates to a protective article and particularly relates to an easy-to-composite multi-layer composite mask and a manufacturing process thereof. The mask comprises a mask body; the mask body consists of a surface layer, an intermediate layer and an inner layer; both the surface layer and the inner layer are non-woven fabric layers; the intermediate layer is an electrostatically-loaded and melt-blown filter material layer; a pure cotton fabric layer is arranged between the surface layer and the intermediate layer; outer edges of the surface layer, the electrostatically-loaded and melt-blown filter material layer and the inner layer are composited by hot melting; the surface layer, the pure cotton fabric layer, the electrostatically-loaded and melt-blown filter material layer, and the inner layer are welded ultrasonically. According to the mask disclosed by the invention, because the electrostatically-loaded and melt-blown filter material layer is adopted by the intermediate layer and the cotton fabric layer can be fused between the surface layer and the intermediate layer, the mask has good filtering effect, low resistance, nice comfort and strong air permeability and water absorption; meanwhile, the multiple layers of materials are composited through ultrasonic welding, so the stitching with threads is avoided and the composite process is simplified.

Description

technical field [0001] The invention relates to a protective article, in particular to an easy-to-composite multilayer composite mask and a manufacturing method thereof. Background technique [0002] At present, the masks on the market are generally made of gauze, cotton and other materials. Although they can play a certain protective role, in order to ensure air permeability, gauze or cotton generally has a low density of yarn or cotton thread, so its filterability is restricted. At the same time, due to the characteristics of cotton cloth itself, it cannot be fused with chemical fiber non-woven fabrics or gauze, so it needs to be stitched or composited by other processes, and the composite process is relatively complicated. Contents of the invention [0003] In order to solve the defects and deficiencies in the above-mentioned prior art, the present invention provides a multi-layer composite mask that is easy to composite and has a simple composite process, good filterin...
