A filter medium is provided comprising a carrier layer; a melt-blown layer; and a spunbond layer. The melt-blown layer is disposed between the carrier layer and the spunbond layer. The spunbond layer comprises bicomponent fibers. The spunbond layer may have a basis weight of from about 10 g/m2 to about 40 g/m2 and may have a thickness of at least about 250 m. Also described herein is a method of producing the filter medium and filters and apparatus comprising the filter medium. The inclusion of a low density bicomponent spunbond layer as a pre-filter layer in the filter medium provides a lower basis weight filter medium with a comparable or improved filtration efficiency to a filter medium comprising a carded nonwoven pre-filter layer, while reducing the amount of materials used.

Nonwoven fabrics are provided that include a first meltblown layer, in which the first meltblown layer comprises a first polymeric material including (i) a first polymer component and (ii) optionally one or more first additives. The first polymer component comprises a first recycled-polypropylene (rPP).

A nonwoven fabric used for a foamed article reinforcing material to be bonded to a foamed material to reinforce the foamed article is a single-layer material in which stacked layers of a web are bonded together, has a thickness of 1 to 8 mm under a load of 7 g/cm.sup.2, and has a delamination strength of 0.05 to 2.45 N/cm. The delamination strength is a value of the pulling force required to peel the bonded layers of the web apart.

The present invention provides a skin-adhesive air-permeable intelligent bandage comprising: a stretchable adhesive antibacterial bioelectrical interface film made of stretchable adhesive antibacterial fibres; a waterproof moisture-permeable protective film for protecting the wound from external contaminants; and a permeable stretchable circuit assembly arranged between the bioelectrical interface film and the protective film. The permeable stretchable circuit assembly comprises: a permeable stretchable circuit board; one or more biosensors constructed on the permeable stretchable circuit board; and electronic components assembled on the permeable stretchable circuit board. The electronic components include: a physiological signal processing module electrically coupled to the one or more biosensors for in-situ wound monitoring; and a drug delivery actuation module electrically coupled to the bioelectrical interface film for adaptive drug delivery for wound treatment. The provided bandage is more convenient, comfortable and efficient without numerous dressings, thereby not hindering the daily activities and life quality of patients.
