Definitions

  • the present invention relates to fabrics having modified surface properties and, more particularly, fabrics having improved liquid barrier and/or repellency properties.
  • component A comprises at least about 50% of the outer surface of the multicomponent fibers.
  • component A can comprise at least two discrete components separated by one or more B components.
  • the multicomponent fibers desirably have an average fiber diameter less than about 25 micrometers and, more desirably, have an average fiber diameter less than about 10 micrometers.
  • the active agent can comprise wetting agents or liquid repellency agents.
  • no single or continuous exposed portions of component B comprise more than about 35% of the peripheral surface of the multicomponent fiber.
  • component B desirably comprises at least about 45%, by volume, of the fiber cross-section.
  • nonwoven fabrics having good liquid barrier and/or repellency properties can be provided wherein the active agent comprises a liquid repellency agent and the multicomponent fibers have an average denier less than about 1.
  • the active agent may comprise less than 0.75%, by weight, of the multicomponent fibers and the nonwoven web may also have a basis weight less than about 50 g/m 2 .
  • such nonwoven fabrics can be provided having an alcohol repellency rating of 50 or more.
  • active agent refers to any chemical compound or composition that imparts or improves at least one physical property or functional characteristic of a fiber surface.
  • wetting agent refers to any chemical compound or composition that makes a fiber surface exhibit increased hydrophilic characteristics such as by lowering the contact angle of an aqueous fluid that comes in contact with the fiber surface.
  • liquid repellency agent refers to any chemical compound or composition that makes a fiber surface exhibit increased barrier or repellency characteristics for a particular liquid such as by increasing the contact angle for the particular liquid that comes in contact with the fiber surface.
  • fabric means a material comprising a network of fibers including, but not limited to, woven or knitted materials, tufted or tufted-like materials, nonwoven webs, and so forth.
  • medical fabric means medically oriented items such as surgical gowns and drapes, face masks, bouffant caps, surgical caps and hoods, shoe coverings, slippers, wound dressings, bandages, sterilization wraps, wipers, garments like lab coats, coveralls, aprons and jackets, patient bedding, and so forth.
  • compositions suitable for use in melt-extrusion processes and that improve alcohol repellency include, but are not limited to, fluorochemicals.
  • fabrics having good alcohol repellency can be provided wherein the multicomponent fibers comprise less than 0.8%, by weight, liquid repellency agent and still more desirably comprise about 0.6% or less liquid repellency agent.
  • Additional materials which are compatible with and which do not substantially degrade the performance of the particular active agent, can optionally be added to and extruded with one or more of the polymeric components.
  • one or more of the individual components of the multicomponent fiber can optionally include additional surfactants, dyes, stabilizers, pigments, fragrances, and so forth.
