Spunbond-meltblown-spunbond laminates made from biconstituent meltblown materials

摘要

Spunbond-meltblown-spunbond nonwoven fabrics having good softness, drape and extensibility, in addition to strength and barrier, are formed from combinations of bicomponent spunbond fibers having low fiber denier and biconstituent meltblown fibers. The spunbond fibers include an outer sheath portion formed using a first polyolefin and an inner core portion formed using a second polyolefin or polyester. The meltblown fibers include first meltblown fibers formed using a polyolefin and second meltblown fibers formed using a polyester.
