Description

Filter structure 【0001】

The invention relates to a filtering structure, in particular to a filtering structure with good air permeability and filtering effect.

【0002】

Filtration structure has always been one of the daily necessities that people often use, such as masks. Nowadays, air pollution is getting more and more serious, whether it is industrial exhaust gas or exhaust gas emitted by steam locomotives, etc., which have a great impact on the environment, and It also has a considerable impact on the health of people, so masks are an indispensable necessity for locomotive riders on locomotives. In addition, for medical treatment, medical masks are also indispensable. For example, a few years ago, there was an epidemic of SARS and avian influenza. Because this virus caused death, the mask was in short supply.

[0003]

Nowadays, there are many kinds of masks, such as paper masks, surgical masks, N95 masks and activated carbon masks. The various masks basically have the basic functions of dustproofing and filtering dirty air. Masks are designed for people's health and are used to prevent visible or invisible substances that are harmful to the human body from entering the body.

[0004]

The dust-removing efficiency of a general mask is based on the barrier efficiency against fine dust. Because small diameter dust can directly enter the alveoli, it has the greatest impact on human health. In general dust masks, the dust-proof method is mechanical filtering, that is, when the dust collides with the mask, the large-particle dust is blocked in the gauze through the barrier of the layer of gauze. However, some fine dust will pass through the gaps of the gauze and enter the respiratory system. Nowadays, there are some dust masks, the filter material is composed of fibers with static electricity. During the process of passing through the filter material, the fine dust is attracted by the static electricity and adsorbed on the filter material, so that the fine dust can be effectively blocked, and the dust is actually achieved. .

[0005]

In general, a good mask should have the following conditions: a mask is well adhered to the user's face, the second filter effect is good, the three breathing resistance is small, and the wearing comfort is good. There are many kinds of filter materials for masks, including ordinary fabrics, animal hairs and non-woven fabrics.
