  • the present application relates to a method for the hydrophilic finishing of Fibers that contain exclusively or predominantly polyolefins or polyester of nonwovens containing polyolefin or polyester fibers and fibers or Nonwovens that are made hydrophilic by this process.
  • the hydrophilic finish of the fiber remains as long as possible without the water permeability of the nonwoven fabric is reduced. If such nonwovens are processed, for example, in diapers, can be used several times without leaking. In this way the wearing time of the diapers is increased and that caused by used diapers Waste decreased.
  • No. 5,045,387 describes, for example, an agent for the hydrophilic finishing of polyolefin fibers, which contains a mixture of an alkoxylated ricinoleic acid derivative, a hydrogenated ricinoleic acid derivative, a C 18 fatty acid and a polyalkoxylated polymethylsiloxane.
  • EP 372 890 B1 discloses fibers which comprise polyolefins or polyesters and have been treated with an agent which comprises a fatty acid diethanolamide, a polyether-modified silicone, a sorbitan fatty acid ester and a metal salt of an alkyl sulfonate. The disadvantage of such preparations can be seen above all in their high price.

  • Nonwovens which are produced either by the so-called “dry laid” method or by the spunbonded method or spunbond method are preferred.
  • the "dry laid” process is based on staple fibers, which are usually separated into individual fibers by carding and then folded together using an aerodynamic or hydrodynamic process to form the unconsolidated nonwoven. This is then combined, for example, by a thermal treatment to form the finished fleece (the so-called "thermobonding").
  • the synthetic fibers are either heated to such an extent that their surface melts and the individual fibers are joined together at the contact points, or the fibers are coated with an additive which melts during the heat treatment and thus connects the individual fibers together.
  • the connection is fixed by cooling.
  • all other processes which are used in the prior art for connecting nonwovens are of course also suitable.
  • Spunbond formation starts from individual filaments which are formed by the melt spinning process from extruded polymers which are pressed through spinnerets under high pressure.
