On May 21, Chengdu Medical Device Industry Association issued the group standard "Melt blown Nonwovens for Masks" (T/CDAMEI 001-2020), which has been implemented since May 22.
It is reported that there are three standards related to melting spraying cloth in China, which are respectively:
Spunbonded/Melt Sprayed/SPunbonded (SMS) Nonwovens (FZ/T 64034-2014)
Melt Blown Nonwovens (FZ/T 64078-2019)

Melt jet nonwovens is applicable to nonwovens produced by melt jet. The final use is not limited to masks. The standard only requires the width, quality per unit area, etc. The standard value of filtration efficiency, permeability and other key indicators is stipulated by the supply and demand contract. Melt-jet Nonwovens for Masks is a group standard for melt-jet nonwovens for masks published for the first time in China. It specifies requirements for raw materials, product classification, basic technical requirements, special technical requirements, inspection and determination methods, and puts forward specific requirements for product labeling.
