Abstract

There is provided a laminate having at least one layer of meltblown elastic fibers bonded on either side with a layer of soft non-elastic fibers of greater than 7 microns in average diameter. The laminate has a drape stiffness less than half of a similar fabric having a layer of meltblown non-elastic fibers in place of the layer of meltblown elastic fibers.

Independent Claims | See all claims (24)

  1. 1. A laminate having a hydrohead of at least 10 millibars comprising at least one layer of meltblown elastic olefin polymer fibers thermally bonded on at least one side with a layer of soft fibers of a nonelastic material greater than 7 microns in average diameter.
  2. 16. A laminate comprising at least one layer of meltblown elastic fibers bonded on either side with a layer of soft non-elastic fibers of greater than 7 microns in average diameter.
  3. 17. A laminate having a hydrohead of at least 10 millibars comprising at least one layer of meltblown elastic olefin polymer fibers thermally bonded on either side with a layer of soft fibers of a nonelastic material greater than 7 microns in average diameter.
  4. 22. An infection control product having a hydrohead of at least 10 millibars comprising at least one layer of elastic olefin polymer meltblown fibers thermally bonded on either side with a layer of conjugate spunbond fibers of a nonelastic material, wherein said laminate has a drape stiffness of at most 2.5 cm.
