Definitions

  • the present invention relates to spin finishes for synthetic filament fibers which contain polyester with a hydrophilic and a hydrophobic part of the molecule as a lubricant.
  • the polyesters are block copolymers of hydrophilic polyethylene glycols and hydrophobic diols, selected from the group of polypropylene glycols, polytetrahydrofurans, polycaprolactone diols, hydrogenation products of ricinusic acid esters, dimer diols, 1,2-alkanediols and alpha.omega-alkanediols, and also the polyhydric carboxylic acids and / or their derivatives linking the polyethylene glycols and hydrophobic diols.
  • the lubricants in the spin finishes should give the filaments the necessary sliding properties. At the same time, however, the lubricants must be temperature-resistant, non-corrosive, easily removable from the fiber and physiologically harmless so that the requirements for the spin finishes can be met.
  • Typical lubricants for spin finishes are vegetable, animal and mineral oils or also synthetic esters, silicones, polyethers, ethoxylated fatty acids and the like (see Ullmanns Encyclopedia of Technical Chemistry, Volume 23, pages 7-9, Verlag Chemie, Weinheim 1983).
  • Dicarboxylic acids, monocarboxylic acids and tetrahydrofuran-alkylene oxide random copolymers are also poorly biodegradable.
  • polyesters from terephthalic acid, ethylene oxide, propylene oxide and / or butylene oxide and, if appropriate, monocarboxylic acids or monohydric alcohols impart improved synthetic fibers "bindability" and "weavability".
  • Polyesters with hydrophilic and hydrophobic molecular parts made from monoalcohols, dicarboxylic acids, secondary alcohols, polyethylene oxide and possibly polypropylene oxide are known as emulsifiers in epoxy resin-containing sizes for carbon and glass fibers from European patent application EP-A-03 93 665. After that
  • polyesters have the polyethylene oxide units at the end of the polymer, since only terminal polyethylene oxide units would have a hydrophilic character. Besides, these sizes are made of an epoxy resin and completely unsuitable for polyesters as spin finishes for synthetic fibers, since the sticky epoxy resins too much stick together the synthetic filaments, which leads to thread breaks.
  • the object of the present invention is to provide spin finishes for synthetic filament fibers which contain lubricants with improved biodegradability.
  • the lubricants should have good lubricating properties due to a hydrophobic part of the molecule and should be easy to incorporate into water by means of a hydrophilic part of the molecule.
  • the lubricants should also ensure easy removal from the fiber and the highest possible temperature resistance.

  • non-crystalline block copolyesters that are liquid at room temperature are desired, it is advisable to use polyethylene glycols with the low molecular weights in the stated amounts.
