Mask Will Decolorize Quality Six Steps To Teach You To Identify Qualified Masks

Recently, many new year masks printed with the words "full of pride", "Fu" and "cartoon cattle" have been selling well because of their festive appearance.

However, some buyers said that this kind of "new year mask" will be decolorized, and some buyers commented that "the smell is particularly heavy" and that although the mask is good-looking, it has some color loss "The collar of the white sweater is rubbed with red, so I dare not use it."

　　 The color is too bright for children to use carefully

"Some businesses print on the surface of masks, mainly for the sake of beauty."

Xu Xiaofang, engineer of Hubei Provincial Fiber Inspection Bureau, said that the state has no special regulations on mask printing, but in GB / T 32610-2016 "technical specification for daily protective masks", it is stipulated that the outer layer of mask shall be tested for color fastness to dry friction and the inner layer shall be tested for color fastness to wet rubbing, and the results shall not be lower than grade 4. In order to prevent the dye from falling off and causing discomfort to the human face and skin.

Xu Xiaofang introduced that the protective performance of the mask mainly depends on two points: one is the quality of the internal meltblown cloth material; the other is the fit between the mask and the face. The closer the mask fits, the better the protective performance will be. Therefore, the printing has little effect on the protective performance of the mask.

At present, the national and industrial standards of protective masks in China are mainly divided into medical masks (including disposable medical masks YY / T 0969-2013, medical surgical masks YY 0469-2011 and medical protective masks GB 19083-2010), daily protective masks (GB / T 32610-2010) and industrial protective masks (GB / T 32610-2010) 2626-2006 and 2019), and now there are new standards for child protective masks and child health masks (GB / T 38880-2020).

According to the standard, children's masks need to be marked with safety warning on the package. For example, children should not make noise or exercise with moderate or above intensity during wearing masks. If respiratory discomfort, skin allergy and other symptoms occur during wearing, they should be taken off in time. Consumers are advised to pay attention to them when purchasing and wearing masks.

Xu Xiaofang suggested that consumers can choose masks that meet the requirements of corresponding standards and technical indicators according to different use scenarios, regardless of whether they are purchased on e-commerce platforms or pharmacies. It is important to see clearly the standards indicated on the mask packaging.

"It's better to choose a non printing mask that is in contact with the skin to avoid the irritation of the dye coating on the face skin." Xu also reminded the public that bright coloured masks are not recommended for children and young children.
