Definitions

  • the invention relates to a process for the hydrophilic finishing of fibers which contain polyolefins or polyesters exclusively or entirely. Special sugar ester ethoxylates are used.
  • the surface of plastic products must be provided with special effects that can either not be created at all or only incompletely for technical reasons, or can only be produced disadvantageously for economic reasons.
  • One such effect is, for example, the improvement of wettability with polar liquids such as water - technical applications are, for example, in the field of the manufacture of hygiene articles.
  • absorbent materials are used to absorb aqueous liquids.
  • this material is covered with a thin, water-permeable nonwoven.
  • nonwovens are usually made of synthetic fibers, such as polyolefin or polyester fibers, because these fibers are inexpensive to produce, have good mechanical properties and are thermally stable.
  • untreated polyolefin or polyester fibers are not suitable for this purpose because their hydrophobic surface means that they do not have sufficient permeability to aqueous liquids.
  • the fiber surface must be made hydrophilic by an appropriate preparation. It is also desirable that the hydrophilic finish of the fiber is preserved as long as possible without the water permeability of the nonwoven being reduced. If such nonwovens are processed, for example, in diapers, they can be used several times without becoming water-impermeable. In this way, the wearing time of the diapers is increased and the waste caused by used diapers is reduced.
  • US-A-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 Cjg fatty acid and a polyalkoxylated polymethylsiloxane.
