Description

mask {Mask}

The present invention relates to a mask, and more particularly, to a mask in which lacquered paper is applied as a lining of the mask.

With the progress of industrialization, the atmospheric environment is getting worse and the types of pollutants are becoming very diverse, and the rate of occurrence of various harmful gases and odor components including heavy metals, fine dust, and VOCs that are fatal to the human body is rapidly increasing. .

Therefore, as interest in atmospheric environmental problems is growing worldwide, high-efficiency air filters are being used to obtain a comfortable living environment and to maintain a high-clean production process along with the development of electricity, electronics, and semiconductor industries.

In terms of use, there are air filters for ventilation, air filters for transportation, industrial dust removal filters, that is, dust collection filters, and various filter filters used in home appliances. In addition, various automobiles are also equipped with air filters.

In addition, individually, people wear a mask including such an air filter to prevent inhalation of germs and fine dust in the air.

On the other hand, microcontaminants are complex mixtures of very small particles and liquid droplets, and are classified into PM2.5 and PM10 based on the particle size, which refer to particle sizes of 2.5 μm and 10 μm or less, respectively. The pollutants of PM2.5 are particularly harmful because of their small size, they can penetrate a person's bronchi and lungs.

For reference, looking at the KF (Korea Filter) certification standards, KF80 blocks more than 80% of fine particles (average particle size 0.6㎛), pressure loss is 60Pa or less, and KF94 is fine particles (average particle size 0.4㎛) 94% or more Blocking and pressure loss of 70Pa or less, KF99 blocks more than 99% of fine particles (average particle size of 0.4㎛), and pressure loss of 100Pa or less. The higher the pressure loss, the more difficult it is to breathe.

In addition, in the case of air filters, the HEPA class has a PM2.5 (2.5㎛) collection efficiency of 99.97%, but a pressure loss of 260Pa is very high, so energy consumption and noise increase when applied to various industrial sites or electronic products have.

Therefore, a filter using a nanofiber web manufactured by electrospinning has been recently proposed to capture and block fine contaminants of PM2.5 (2.5㎛) level of ultrafine dust.

As a mask for protecting the respiratory tract from particulate harmful substances such as yellow dust or fine dust and harmful bacteria such as influenza or pneumonia-causing viruses, a mask with a level of KF94 or higher is preferred by users.

Each of these masks is manufactured in a structure in which an electrostatic filter or a filter using a nanofiber web is embedded between a non-woven fabric and a lining.

Recently, the appearance of yellow dust or fine dust from China is increasing, and due to the pandemic of influenza or pneumonia-causing virus, the frequency of wearing a mask sharply increases or when a shortage occurs, it is recommended to reuse the mask in a dried state. cases are increasing.

However, even if the KF94-class mask with a built-in filter using an electrostatic filter or a nanofiber web has a three-dimensional structure applied with a hard shell, the pressure loss is large, making it difficult to breathe when worn for a long time.

Therefore, when the mask is worn for a long time, the user's breath or saliva stays inside the mask and the lining becomes moist, which creates an environment in which bacteria can breed, which is undesirable in terms of hygiene. In addition, in the case of a user with bad breath, breath or saliva stays inside the mask and the wearability is deteriorated due to bad breath. Moreover, breath or saliva staying inside the mask may permeate into the inside and affect the electrostatic filter, thereby degrading the performance of the electrostatic filter.

Since the performance of the electrostatic filter of the KF94-class mask is deteriorated and reused after washing, the mask is worn while the inside is moist.
