In addition to making masks, what are the other uses of meltblown cloth?

Meltblown cloth is made of polypropylene as the main material, which can be used for air, liquid filtration materials, isolation materials, absorption materials, warm materials and oil-absorbing materials.

1. Different materials: meltblown cloth masks are made of polypropylene materials; Medical masks generally adopt a multi-layer structure, with a single-layer spunbond layer on both sides and a single-layer or multi-layer meltblown layer in the middle.

2. The fiber diameter is different: the fiber diameter of the meltblown cloth mask is 1 5 microns; The fiber of a medical mask is micron in diameter.

In addition to the above two types of masks, common masks include the following:

1. Activated carbon mask: It has a good filtering of bacteria, which can adsorb odors, formaldehyde and slight toxic gases, but due to poor air permeability, long-term use may lead to hypoxia.

2. Medical gauze-free mask: It has a good effect on bacterial filtration, is breathable and comfortable, clean and hygienic, and is a mask commonly used by modern doctors.

3. Cotton mask: a modern and practical mask, the main feature is warmth.

4. Dust mask: It is generally a cup type, which can be effectively attached to the mouth and nose, so as to achieve the effect of dustproof, and generally appears in factory processing and other occasions.

5. N95 and above masks: It can be extremely effective in prevention and control, and it is more effective if you want to prevent and use N95 or above masks. The dust filtration effect and sealing effect of this mask are good, but it will cause stuffiness and discomfort after wearing it for a long time.

China's mask standards are divided into three categories: the civil mask standard is represented by GB T32610 "Technical Specifications for Daily Protective Masks", which is mainly aimed at air quality pollution of the environment; The standard for protective masks in the industrial field is represented by GB 2626-2006 "Self-priming and Filtering Anti-particulate Respirators for Respiratory Protective Equipment", which is mainly applicable to industrial workplaces.

The standards in the medical field are: GB 19083-2010 "Technical Requirements for Medical Protective Masks", YY 0469-2011 "Medical Surgical Masks", and YY T 0969-2013 "Disposable Medical Masks", which are mainly applicable to the medical field. According to the use scenarios and groups of users, what standards should be used to produce sanitary masks used by ordinary consumers, which has caused confusion to manufacturers and market supervision.

In order to better meet the urgent needs of the public for sanitary masks, facilitate the adoption and application of enterprises that produce and switch to masks in the current emergency, and at the same time ensure product quality and facilitate market supervision, the China Industrial Textiles Association and the Science and Technology Development Department of the China National Textile and Apparel Council have organized mask manufacturers, filter material manufacturers, testing institutions and colleges and universities to urgently establish the group standard of "civil sanitary masks" to the Standardization Technical Committee of the China Textile Federation.

The standard is led by the China Industrial Textile Industry Association, and under the guidance of experts from the medical and personal protection industries and universities, mask manufacturers, filter material manufacturers, testing institutions and colleges and universities are organized to jointly draft the standard. The promulgation of this standard will provide technical support for mask manufacturers, provide a basis for market supervision, and facilitate consumers to choose suitable masks.

The mask contains meltblown cloth.

Masks can play a protective role, and the core is to rely on meltblown cloth. A suitable layer of meltblown cloth can ward off viruses.

Meltblown cloth uses polypropylene as the main raw material and is composed of microfiber. The meltblown cloth used in medical protective masks has a finer fiber diameter, which can reach 1 to 4 microns, and the holes formed by the meltblown cloth are also very thin, making it impossible for viruses to pass through.

Some masks, such as surgical masks and anti-smog masks, have limited protection against viruses due to their different production processes, even if they contain meltblown cloth inside. And simple cotton and gauze masks, no matter how many layers there are, will not increase the protection against the virus.

Mask selection

1. The types and protective effects of masks, from strong to weak, are medical protective masks, medical surgical masks, ordinary medical masks, and ordinary masks.

2. Ordinary masks, such as cotton, sponge, activated carbon, and gauze, can only prevent dust and haze, and cannot prevent the spread of bacteria and viruses.

3. Ordinary medical masks can be used in non-crowded public places.

4. Medical surgical masks, the protective effect is better than ordinary medical masks, and they can be worn in crowded places in public places.

5. Medical protective masks (N95 KN95) can be worn by front-line medical staff when they come into contact with confirmed or suspected new crown pneumonia patients, fever clinics, on-site investigation sampling and testing personnel, and can also be worn in high-density occasions or closed public places.

6. Try not to use ordinary cotton, gauze, activated charcoal and other masks, but if necessary, it is better than nothing.
