Description

Eco-friendly small intestine mask with replaceable filter {ECO-FRIENDLY FABRIC MASK WITH FILTER REPLACEMENT}

The present invention relates to a mask made of a small chang fabric woven using eco-friendly cotton fibers, and a mask manufactured so that the filter inside the mask can be replaced.

Recently, the average temperature of the earth's atmosphere is rising due to the greenhouse effect caused by global warming, and environmental problems such as abnormal climate are continuously becoming issues around the world. In Korea, environmental problems such as yellow dust, fine dust, and air pollution, which are directly related to the health of the whole nation, are emerging as big social problems to be solved, and are attracting attention as a sustainable topic.

The definition of eco-friendly fiber is “fiber that is environmentally satisfactory and does not pose a threat or harmful to the environment”. The characteristics of eco-friendly fibers include characteristics related to environmental preservation and purification and characteristics related to contributing to environmental improvement. It may have an effect of blocking harmful substances, replace synthetic fibers, contribute to energy consumption reduction by weight reduction, or may mean a case of recycling waste.

On the other hand, Sochang is a fabric in which cotton spun yarn is loosely woven in plain weave, and is an eco-friendly material generally used in white after undergoing refining and bleaching processes. It has very high thermal conductivity and very low coverage, has good water absorption and breathability, and dries quickly.

The freshly made small chang is stiff enough to be called a waterproof cloth because it is fed with grass. So, it is necessary to go through a somewhat laborious 'refining' process of boiling and taming Sochang. After three or four refining processes, the loose weave becomes denser and softer, and the absorption capacity is improved. In this respect, Sochang can be said to be a fabric that is tamed by those who use it in daily life.

In addition, Sochang is a natural fiber made from 100% cotton, and it is used in various ways from diapers to cords used to tie coffins. Recently, the controversy over sanitary napkins containing harmful substances has grown, attracting attention among those looking for cotton sanitary napkins and diapers.

Recently, as the inflow of foreign air pollutants such as yellow dust and smog has increased, and since 2013, the number of diesel vehicles emitting a large amount of nitrogen oxide, a precursor of fine dust, has increased rapidly, resulting in a rapid increase in the generation of high-concentration fine dust. As it is urgent to establish fine dust intensive management and reduction measures, restrictions on the operation of old diesel vehicles are being promoted to reduce fine dust and automobile emissions, which are the main culprits of fine dust and air pollution in metropolitan areas, but the amount of fine dust is still increasing.

Accordingly, the number of people wearing masks to protect the respiratory system from fine dust or yellow dust in daily life is increasing, but the existing masks for blocking fine dust are mostly electrostatic filter types, so they are very vulnerable to moisture. Therefore, if moisture is attached to the mask by inhalation while wearing the mask, the ability to block fine dust rapidly decreases. In addition, while wearing the mask, a small gap with the skin occurs, and dust and contaminants leak through the gap, and the mask does not function properly.

On the other hand, due to the novel coronavirus (COVID-19) that swept the world from the end of 2019 to the beginning of 2020, the importance of personal hygiene and masks to prevent droplet transmission has risen, temporarily making it difficult to supply and supply reusable masks. increased interest in

The conventional mask has a problem that the tissue of the filter formed in multiple layers is dense, which causes inconvenience to the wearer's breathing, and the conventional filter is generally made of a synthetic resin material, so that it is not beneficial to the human body itself. Furthermore, because the moisture generated during the respiration process causes a significant growth of bacteria in the filter, antibacterial agents are used to prevent this. There was a risk of harm.

In addition, due to the fear of droplet infection, etc., as long-term and close wearing of the mask continues, problems such as irritation of the skin, discomfort due to moisture, and an unpleasant odor are continuously raised. The need is increasing.
