WHAT ARE THE DIFFERENT TYPES OF NONWOVEN FABRICS?
The main types used in the medical field are Polypropylene (PP) Spunbond, Meltblown, SMS and Spunlace. The fabrics vary in their cost and in the properties/characteristics they offer. PP Spunbond: This is the most basic, cheapest and widely used non-woven in the Indian market. We use a range of GSM’s depending on the product. Our standard GSM’s range from 12 – 40 Gsm in White, Medical Blue and Medical Green. Meltblown: This fabric is known for its filtration qualities. It is used in the middle layer of our 3-ply mask and provides the bacteria filtration. The fabric we use provides a Bacteria Filtration Efficiency (BFE: See Below for Explanation) of minimum 98%. SMS: SMS is a trilaminate nonwoven: 1 layer of meltblown nonwoven is in a sandwich between 2 layers of spunbond. The meltblown has a very high density web of fine fibers and is suitable for applications requiring filtration (of particulates, bacteria, fluids). The 2 layers of spunbond are added to provide the necessary strength
