SMS Nonwoven Fabric and SMMS Nonwoven Fabric have several differences:
1.Composition:
(1)SMS Nonwoven Fabric: Comprises three layers - spunbond, meltblown, and spunbond polypropylene.
(2)SMMS Nonwoven Fabric: Consists of four layers - two spunbond layers sandwiching a meltblown layer, followed by another spunbond layer.
2.Number of Layers:
(1)SMS Nonwoven Fabric: Consists of three layers.
(2)SMMS Nonwoven Fabric: Has an additional spunbond layer, totaling four layers.
3.Enhanced Barrier Properties:
(1)SMMS Nonwoven Fabric: With the extra spunbond layer, SMMS typically offers improved barrier properties compared to SMS, making it more effective in blocking fluids and contaminants.
4.Increased Strength and Durability:
(1)SMMS Nonwoven Fabric: The additional spunbond layer enhances the fabric's strength and durability, making it more suitable for applications requiring higher tensile strength and resistance to tearing.
5.Enhanced Fluid Repellency:
(1)SMMS Nonwoven Fabric: Due to its additional layer, SMMS may exhibit superior liquid repellency compared to SMS, providing better protection against fluid penetration.
In summary, while both SMS and SMMS nonwoven fabrics share similar structures and are commonly used in various industries, SMMS offers additional strength, durability, and barrier properties due to its extra spunbond layer.
