Definitions

  • anion active compounds such as highly sulphonated non-mineral oils of the type sold under the trade-name Prestabit Oil to viscose solutions in order to inhibit turbidity or milkiness in the rayon.
  • Prestabit Oil a compound of the type sold under the trade-name
  • the anion active compound in the viscose may -counteract or retard the effectiveness of the cation active compound in the spinbath with respect to spinneret incrustation.
  • Another object of this invention is to use small amounts of a cation active compound either in the viscose solution whereby it will get into the spinbath'during the spinning operation, or add it directly to the spinbath in addition to adding it to the viscose.
  • a further object of the invention is to utilize a particular class of cation active compounds that k are good dispersants and are sufiiciently soluble and stable in both alkali and viscose to prevent 'milkiness in the yarn while at the same time are sufficiently soluble and stable in the acid spinbath to prevent spinneret incrustation.
  • R represents an aliphatic chain having from 8 to 24 carbon atoms therein and preferably from 12 to 14 carbon atoms.
  • a; or y is at least one, and r-l-y is the total number of alkylene oxide chains which may be as low as 5 without any definite restriction on the upper limit although 12 to 18 or about 15 have been found .to be quite effective, and n is a small whole number from 2 to 4, both inclusive.
  • Ethomeen 0/25 and Ethomeen 8/25 Specific Ethomeens which have proved very effective in preventing milkiness and spinneret incrustation are known as Ethomeen 0/25 and Ethomeen 8/25. Resolving these into their structural formulate the extent possible they are:
  • the length of the aliphatic chain R depends on the oil from which the parent amine is prepared,
  • the long chain aliphatic tertiary amine-alkylene oxide condensate is added in small quantities, e. g., 0.12% to 0.24% based on the weight of cellulose to the viscose and, if required, lesser amounts to the acid spinbath based on the weight of the spinbath,
  • the viscose' is otherwise prepared in the normal manner and thereafter extruded through minute spinneret orifices into an acid spinbath to form filaments and the like therefrom. It was determined on examination of the finished rayon that it was 1- more 'efiective than Prestabit Oil in preventing inilkiness, even when five times as much Prestibit Oil was used. Furthermore, it was quite efiective in inhibiting spinneret incrustation.
  • Ethomeen C/ and S/25 were added to the viscose in 0.12% and 0.24% quantities based on the weight of cellulose. These viscoses were spun in the normal manner at the normal maturity of 9.8 and at a higher maturity of 11 to 11.5. On examination of the finished rayon it compared favorably with, or was even superior in appearance to, rayon containing Prestabit Oil. 3 I g When the Ethomeens were added to the viscose in the above mentioned quantities and the viscose was spun in an acid spinbath containing cation active. material, it was determined that the pressure build-up behind the spinnerets was reduced markedly, indicating excellent inhibition of spinneret incrustation. This was confirmed by subsequent microscopic examination of the spinnerets.
  • the step which comprises spinning the viscose filaments in the presence of a long chain aliphatic tertiary aminealkylene oxide condensate formed from the reaction of a lon chain aliphatic primary amine with an alkylene oxide whereby milkiness in the filaments and incrustation. of the orifices are inhibited.
  • the step which comprises spinning the viscose filaments in the presence of a small amount of a long chain aliphatic tertiary amine-alkylene oxide condensate formed from the reaction of a long chain aliphatic primary amine with an alkylene oxide whereby milkiness in the filaments and incrustation of the orifices are inhibited.

  • the step which comprises spinning the viscose filaments in the presence of a long chain aliphatic tertiary amine-ethylene oxide condensate formed from the reaction of a long chain aliphatic primary amine with about 15 moles of ethylene oxide whereby milkiness in the filaments and incrustation of the orifices are inhibited.
  • R represents an aliphatic chain having at least 8 carbon atoms therein and :c-l-y equals the total number of moles of ethylene oxide at least 5, fortuitously separated into two chains to form the tertiary amine whereby milkiness in the filaments and incrustation of the orifices are inhibited.
