Disposable mask medical mask is now a more popular mask, which is deeply loved and welcomed by people. Then which is better, non-woven cloth or melt blown cloth? What is the difference between mask non-woven fabric and melt blown fabric?
Which is better, non-woven cloth or melt blown cloth for disposable mask
Melt blown cloth mask is better. Although the protective effect of disposable gauze free mask is also very good, the effect will be worse than that of melt blown cloth. You should know that melt blown cloth is the core material of mask. Melt blown cloth mainly takes polypropylene as the main raw material, and the fiber diameter can reach 1 ~ 5 microns. It has many voids, fluffy structure and good anti wrinkle ability, The superfine fiber with unique capillary structure increases the number and surface area of fibers per unit area, so that the melt blown cloth has good filtration, shielding, heat insulation and oil absorption. The disposable gauze free mask is made of two layers of fiber non-woven fabric professionally used for medical and health, with an additional layer in the middle. More than 99.999% of the filter spray cloth is filtered and sterilized by ultrasonic welding, which can meet the protection needs in daily life, and the spray cloth can be used in higher places.
Difference between mask non-woven fabric and melt blown fabric
In fact, the whole process of melt blown fabric is called melt blown non-woven fabric. The scope of "non-woven fabric" is wide. Products mainly made by the production process of "non-woven fabric" can be called non-woven fabric, and melt blown non-woven fabric is one of them. Secondly, the composition of non-woven fabric can be polyester, polypropylene, nylon, spandex, acrylic, etc. melt blown non-woven fabric is also a kind of non-woven fabric; Masks are mainly made of non-woven fabrics. Generally, the three layers of non-woven fabrics of flat masks are made of PP non-woven fabrics and melt blown non-woven fabrics respectively. The upper and lower layers are PP non-woven fabrics, and the middle layer is melt blown fabrics, which plays a vital role; N95 mask is composed of needle punched cotton, melt blown cloth and non-woven fabric. Finally, the classification of masks is not based on non-woven fabrics, masks and melt blown cloth masks, but mainly medical masks and civil masks. Medical masks are divided into medical protective masks, medical surgical masks and medical nursing masks, which are based on the relevant production standards of medical masks.
Is the anti-virus effect of disposable mask good
Whether the anti-virus effect of disposable masks is good or not can not be generalized at this time. It depends on what kind of disposable masks are. Not all disposable masks can be anti-virus. Only medical disposable masks purchased through formal channels and in line with national standards can effectively block viruses, such as common disposable medical surgical masks and medical protective masks; In life, ordinary people wearing disposable medical surgical masks can prevent the cross transmission of the virus; Medical protective masks are the masks with the highest protection level. Professional masks such as N95 and n99 masks should be left to front-line medical personnel. In fact, both disposable medical surgical masks and protective masks need to be replaced regularly and should not be worn for a long time. Otherwise, it is not conducive to anti-virus, but easy to increase the probability of virus infection.
How to distinguish whether the mask is melt blown cloth
The details are as follows:; To judge whether the mask is melt blown cloth, you can cut the mask, and then observe that the melt blown cloth in the middle layer is located in the middle layer of the mask, which is significantly different from the spunbonded cloth on the surface layer. Generally, there is a significant difference between qualified masks and fake masks under the same light source. Even under natural light, qualified products are a little opaque when worn; Secondly, the melt blown cloth has static electricity. Electrostatic adsorption can be used to verify whether the melt blown cloth is charged, so as to verify whether it is true.
