SSMMS is a nonwoven fabric made using a combination of spunbond and meltblown processes. The abbreviation stands for “Spunbond x 2, Meltblown x 2, and Spunbond x 1,” which refers to the layers of the fabric. In this case, the fabric has two layers of spunbond, two layers of meltblown, and one layer of spunbond, for a total of 5 layers. The combination of spunbond and meltblown layers in SSMMS fabric results in a solid yet lightweight and breathable material. It is often used in various applications, including medical and hygiene products, filtration materials, and protective clothing.
