Problems solved by technology

However, cotton gauze masks can only filter general dust and cannot purify exhaust gas, especially chemical carcinogens such as N-nitroso compounds (NNC) and their precursors are widely present in some production processes and environments of the above-mentioned industries. Medical research shows that long-term exposure of workers to such harmful substances can lead to a high incidence of cancer after inhalation by the human body

Abstract

The present invention provies a kind of gauza mask, which has the comprehensive effects of intercepting and degrading cancerogenic N-nitroso compound and other harmful matters and is dustproof, comfortable, sweat absorbent and reusable after being cleaned. The mask has outer layers of cotton yarn, inner filtering layer of polypropylene and Dacron short staple and nose rest of PVC material and iron wire. It is produced through planar smelting and jointing process or rolling supersonic welding process. The mask is used in rubber, plastic, pesticide, printing and other industry.

Description

technical field [0001] The invention relates to a gauze mask, in particular to a melt-heat welded gauze mask and a manufacturing method thereof. It is widely used in environments where workers in rubber, rubber and plastics, pesticides, printing, leather, building materials, light industry, food, metallurgy, automobile industry, mining, chemical, petrochemical and other industries are exposed to such dust and harmful substances for a long time. Background technique [0002] The cotton gauze masks currently on the market are made of several layers of cotton gauze sewn with cotton thread. After long-term use, this kind of gauze mask has been proved to have the effect of dustproof, isolating germs and keeping warm, and wearing a gauze mask is harmless to the human body. , contact with human skin will not cause allergies. However, cotton gauze masks can only filter general dust and cannot purify exhaust gas, especially chemical carcinogens such as N-nitroso compounds (NNC) and ...
