SMS and Composite Laminate Production Lines
topic
SMS composite nonwoven production lines combine spunbond-meltblown-spunbond layers on a single continuous line through sequential beam and die stations depositing layers on the same collection belt, with the spunbond layers providing tensile strength and abrasion resistance while the meltblown interlayer provides barrier and filtration efficiency, producing the SMS fabrics used in surgical gowns, hygiene backsheets, and protective clothing at 20 to 80 grams per square metre.
Role
Produces the dominant medical barrier and hygiene nonwoven material type by combining the complementary properties of spunbond strength and meltblown barrier in an integrated production process that eliminates the separate lamination step required when producing and bonding layers independently, with SMS composite nonwoven being the primary material for surgical gowns, face mask middle layer, and hygiene backsheet applications requiring simultaneous barrier and strength performance.
