In sanitary napkins, this nonwoven hydrophobic backsheet back layer serves as the backsheet. This prevents water from evaporating into it. Hydrophobic spun bond non woven fabrics are used to create this nonwoven hydrophobic backsheet back layer. The majority of nonwoven fabric is produced using the spin bonding technique, which offers high tensile strength and abrasion resistance. Softness, cleansing, leakage control, lifespan, and safety are just a few advantages that nonwovens offer to users of absorbent hygiene products.
