With the continuous resumption of classes in schools around the world, the demand for children's masks is gradually increasing. There are many kinds of children's masks on the market, and the price is also uneven. How to choose a safe, useful and high-quality mask has attracted much attention.
A few days ago, China issued the "technical specifications for children's masks" as an introductory national standard, which makes special rules for data, wearing, application and other indicators. This reporter interviewed the association, experts and mask manufacturers participating in the formulation of the standard. When buying children's masks, these details should be "polished"!
With the advent of the new semester, the epidemic prevention and control has become normalized. It seems that it is consistent for primary and secondary school students to carry spare masks on campus.
Masks are the "necessary equipment" of students and the first choice of parents in their "school start list". As a weapon against COVID-19, the importance of respirators is obviously.
No more raw materials, safety should be put in the first place, wearing masks is for useful protection, masks themselves can not become a "source of pollution". What kind of mask is suitable for children? Will surface printing have a safety impact? How to judge visually from appearance and data? Let's talk about the mask factory
Data directly touching children's skin, its safety is an important consideration in the selection of masks.
"The technical specification for children's masks puts forward 19 primary functional indicators, including safety, protection and comfort, with safety as the main premise." Li Lingshen, President of China Industrial Textiles Industry Association, said that two types of products, child protective masks and child health masks, have been standardized. When the filtration power of clear particles is no less than 95% and 90%, higher requirements have been put forward for the selection of raw materials of manufacturers.
"Compared with adults, an important difference of children's masks is that they pay more attention to reducing cardiopulmonary burden." A person in charge of TEDA clean company, a manufacturer of mask filter materials, said that a safe mask needs a strong "heart", that is, the melt blown cloth should be low enough resistance and high enough efficiency.
In the selection of non-woven fabrics, the mask raw materials should be standardized and clear, and recycled materials should not be used“ Production enterprises must not choose non-woven materials added with recycled materials or calcium carbonate fillers for low cost, which often have fluorescent agents. " Cao Jun, chairman of Lanhe medical, a children's mask manufacturer, suggested.
It is reported that children's masks are divided into two types according to their functions: protective and hygienic.
The protective children's mask is mainly three-dimensional, which is suitable for medium pollution or potential medium risk environment, such as station, public transportation, supermarket and other scenes in the high incidence season of haze and influenza.
The sanitary children's mask is mainly flat type, which can be used in low pollution or low risk environment, such as restaurants, classrooms, dormitories and other scenes in daily cold, flu and other events.
"The difference between children's masks and adult masks lies in the respiratory resistance and air tightness of masks." As an enterprise representative, Cao Jun, chairman of Lanhe medical, participated in the drafting of the new international technical specifications for children's masks. He said that children '.
Therefore, when planning masks, children should pay attention to the respiratory resistance of masks, and give children more breathing space when wearing masks to reduce their respiratory resistance; Moreover, it is necessary to ensure the air tightness of the mask, so as to make it more suitable for children's face; Children are a group of consumers who are more sensitive to comfort. As for the selection of fabrics and other accessories, we should improve the comfort to the greatest extent while satisfying the above requirements.
Children's masks are not the "reduced version" of adult masks, but the "upgraded version" of adult masks. Naturally, children's masks can not enter the market without the "severe punishment" and "strict control" of the regulatory authorities. Only by strengthening the supervision and spot check on the production and sale of children's masks, including online sales, can we do our best to build a safe and focused production and sale chain.
