Long-time reusable mask and preparation method thereof

Abstract

The invention discloses a long-time reusable mask and a preparation method thereof. The long-time reusable mask comprises a mask body and hanging belts arranged on the two sides of the mask body, andthe mask body comprises a pure cotton cloth surface layer, an isolation non-woven fabric layer, a nano bionic fiber membrane layer, an isolation non-woven fabric layer and a pure cotton cloth skin layer which are sequentially arranged from outside to inside. The long-time reusable mask can be stored for a long time, repeatedly disinfected and used, and effectively obstructs bacteria and viruses.

Description

technical field [0001] The invention belongs to the technical field of masks, in particular to a long-term reusable mask and a preparation method thereof. Background technique [0002] At present, the demand for masks is soaring all over the world. The melt-blown cloth known as the "heart" of masks is in short supply, and the price continues to rise. waste and environmental pollution. At present, the methods for preparing masks mainly include: melt-blown non-woven fabric technology, spun-bonded non-woven fabric technology and woven fabric weaving technology. The materials used are often polypropylene and cotton fibers, and the fiber diameter in the spun-bonded non-woven fabric is relatively thick. Generally between 15 and 40 μm, the average diameter of the fibers in the melt-blown non-woven fabric is less than 5 μm, but the thickness is uneven, and the traditional disposable medical masks and N95 masks mainly rely on the "electrostatic adsorption" of the melt-blown non-wove...

At present, the methods for preparing masks mainly include: melt-blown non-woven fabric technology, spun-bonded non-woven fabric technology and woven fabric weaving technology. The materials used are often polypropylene and cotton fibers, and the fiber diameter in the spun-bonded non-woven fabric is relatively thick. Generally between 15 and 40 μm, the average diameter of the fibers in the melt-blown non-woven fabric is less than 5 μm, but the thickness is uneven, and the traditional disposable medical masks and N95 masks mainly rely on the "electrostatic adsorption" of the melt-blown non-woven fabric as the main filtering method , after contacting water and other substances, it will gradually lose static electricity, resulting in a sharp drop in filtering effect. In view of this, it is necessary to study a long-term reusable mask and its preparation method
