Definitions

  • the invention relates to a process for the hydrophilic finishing of fibers which contain polyolefins or polyesters exclusively or entirely. Special alkyl 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 from synthetic fibers, such as polyolefin or polyester fibers, because these fibers are inexpensive to produce are, have good mechanical properties and are thermally resilient.
  • 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. This agent must be applied from the outside to the surface of the fibers or films.
  • EP-A-400,622 describes a method for imparting hydrophilic properties to nonwoven materials containing hydrophobic fibers.
  • a composition containing special polyoxyalkylated secondary or tertiary amines is introduced into a molten composition containing polyolefin before spinning.
  • EP-B-372 890 describes fibers based on polyolefin or polyester with a lubricant adhered to the surface.
  • This lubricant comprises a mixture of (1) fatty acid diethanolamide, (2) a polyether-modified silicone, (3) a sorbitan fatty acid ester and (4) a metal salt of an alkyl sulfonate; Components (1) to (4) are available in special proportions. According to page 3, lines 20-26, the mixture of components (1) to (4) is applied to the surface. This technique of applying the mixture containing the four components to the surface of finished fibers is also explained in more detail on page 4, lines 6-9. There are listed as application techniques: a) the use of rollers, b) spraying and c) immersion.
  • EP-B-616 622 relates to extrudable, compostable polymer compositions comprising an extrudable, thermoplastic polymer, copolymer or mixtures thereof which contains a degradation-promoting system composed of an autooxidative component and a transition metal.
  • the autooxidative system comprises a fatty acid, a substituted fatty acid or derivatives or mixtures thereof, the fatty acid 10 to Has 22 carbon atoms and contains at least 0.1% by weight of unsaturated compounds and at least 0.1% by weight of free acid.
  • the transition metal is contained in the composition in an amount of 5-500 ppm in the form of a salt and selected from the group cobalt, manganese, copper, cerium, vanadium and iron.
  • the composition should be in the form of a film about 100 microns thick at 60 ° C and a relative humidity of at least 80% biodegradable within 14 days for embrittlement.

  • hydrophobic fibers are made wettable by water by means of hydrophilization, which, for example, improves the washability of Synthetic fiber articles as well as for a better wearing comfort of such articles are useful.
  • measurement-technical indicators of successful hydrophilization are, for example, wetting (the surface spread of a liquid) or the height of rise (a measure of the speed with which water is transported in textile fabrics against gravity ).
  • hydrophilization synonymously for this also the term “hydrophilic finishing” is used below - is understood to mean that polyolefin or polyester surfaces which form a wetting angle of more than 90 ° with water - that is "Hydrophobic" interfaces - be modified by a special measure so that their critical angle is shifted to smaller values after this measure. These are rather dynamic interactions of appropriately modified polymer surfaces with molecules or substrates not immobilized, but in flexible contact with the polymer surface. In this regard, the effects that fall under the concept of hydrophilization are expressly differentiated from phenomena in which molecules or substrates are in permanent fixation in contact with the polymer surface, such as is the case with coatings and bonds or with dyeing and printing is.
