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 ricinate esters, dimer diols, 1,2-alkanediols and alpha, omega-alkanediols, and also the polyethylene glycols and hydrophobes Diol-linking polyvalent carboxylic acids and / or their derivatives.
  • 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 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 (cf. Ullmanns Encyclopedia of Technical Chemistry, Volume 23, pages 7-9, Verlag Chemie, Weinheim 1983).
  • Japanese published patent application JP-A-63/235576 discloses spin finishes for polyester fibers based on polyesters made from dicarboxylic acids, monocarboxylic acids and tetrahydrofuran-alkylene oxide random copolymers. However, these are also poorly biodegradable. According to Japanese published patent application JP-A-62/006982 (cf. Chemical Abstracts, Vol. 107: 79426c), applied polyesters made of terephthalic acid, ethylene oxide, propylene oxide and / or butylene oxide and, if appropriate, monocarboxylic acids or monohydric alcohols impart improved "bindability" and "weavability". There is no indication of the importance of a hydrophobic and hydrophilic part of the molecule in polyester. It is also exclusively polyester based on aromatic terephthalic acid, which is poorly biodegradable.
  • Polyesters with hydrophilic and hydrophobic molecular parts from monoalcohols, dicarboxylic acids, secondary alcohols, polyethylene oxide and optionally polypropylene oxide are known as emulsifiers in epoxy resin-containing sizes for carbon and glass fibers from the European patent application EP-A-03 93 665. According to the teaching of this type, it is essential to the invention that the polyesters have the polyethylene oxide units at the polymer end, since only terminal polyethylene oxide units would have a hydrophilic character. Besides, these sizes are made of an epoxy resin and completely unsuitable for polyester as spinning preparations for synthetic fibers, since the sticky epoxy resins stick the synthetic filaments too much together, causing 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 sliding 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.
  • the block copolyesters containing the invention are prepared by esterification or transesterification of the carbonic acid diesters, the dicarboxylic acids, their esters and / or their anhydrides with the hydrophilic polyethylene glycols (block A) and the hydrophobic diols (block B), preferably in the presence of an esterification catalyst and with removal any water of reaction or the alcohol released from the esters.
  • block A hydrophilic polyethylene glycols
  • block B hydrophobic diols
  • polyethylene glycols with an average molecular weight of 450 to 20,000, preferably 600 to 3,000, in particular 800 to 2,000, are used as hydrophilic diols (block A) to build up the block copolyesters.
  • Polyethylene glycols are commercially available products and are obtained industrially, for example, by base-catalyzed attack by alcoholate anions on ethylene oxide with ring opening and polymerization (see Ullmann's Encyclopedia of Industrial Chemistry, Volume 19 (1980), Verlag Chemie, Weinheim, pages 31-38). Within the specified molecular weight range, the polyethylene glycols with different molecular weights can be taken as block A in any mixtures.
  • polyethylene glycols with molecular weights of 62 to less than 450 in minor amounts, preferably in amounts of 0.01 to 20% by weight, based on the total amount of polyethylene glycol.
  • the emulsifiability of the block copolyesters is advantageous if there are no polyethylene glycol components with molecular weights below 450.
  • non-crystalline block copolyesters that are liquid at room temperature it is advisable to use polyethylene glycols with the low molecular weights in the stated amounts.
  • hydrophobic diols selected from the group of the polypropylene glycols, polytetrahydrofurans, polycaprolactone diols, hydrogenation products of ricinate, 1,2-alkanediols, alpha, omega-alkanediols and / or dimerdiols are used as block B.

  • Polytetrahydrofurans are also commercially available products and can be obtained by ring-opening polymerization of tetrahydrofuran (see Ullmann's Encyclopedia of Industrial Chemistry, Volume 19 (1980), Verlag Chemie, Weinheim, pages 297-299). Suitable polytetrahydrofurans have a molecular weight between 200 to 8,000, preferably 800 to 6,000.
  • Polycaprolactone diols are also commercially available products and can be used as catalysts at temperatures between 20 ° C. to about 150 by ring-opening polymerization of ⁇ -caprolactone with aliphatic and / or aromatic diols, for example by the so-called interox process in the presence of Lewis acids or organic acids ° C. Because of their biodegradability, preference is given to polycaprolactone diols which have been prepared by ring-opening polymerization using alpha, omega-aliphatic diols having 2 to 36 C atoms, preferably straight-chain, saturated, aliphatic diols having 2 to 22 C atoms. In principle, however, all polycaprolactone diols with molecular weights of 400 to 4,000 are suitable.
