Definitions

  • My present invention relates to a process of treating cellulosic fibers.
  • One of its objects is an improved process of making resistant to washing cellulosic fibers treated with resins. Further objects will be seen from the detailed specification following hereafter.
  • the present invention produces a great improvement in the application of the resins in question for diminishing the tendency of cellulosic fibers or fabrics to crease in that this resistance is attained without material diminution of softness of feel and with retention of resistance of the resinous material to removal by washing.
  • the cellulosic material before it is impregnated with resin or sub stances which yield resin, is soaked in a solution or emulsion of wax.
  • the operation may consist in thoroughly saturating the fiber or the fabric with a suitably composed emulsion of wax, then centrifuging or pressing and finally subjecting the material to the usual impregnation with resin.
  • wax liquor can be added directly to the bath which is to impart resitance to creasing, so that As waxes may be used natural or artificial waxes, as well as products resembling wax, although not being strictly waxes in their chemical composition.
  • the process may also be conducted by first impregnating the cellulose material with the solution of wax and a compound having the ter dency to accelerate the condensation with formaldehyde to produce resin and, after drying, treating the goods with formaldehyde vapour at a raised temperature.
  • the goods to be treated are saturated with an emulsion of 3 per cent. strength of equal parts of Japan wax and the sodium salt of oleic-acid- N-methyl-tauride, the operation being conducted in a vat or on afoulard at ordinary temperature; the goods are then pressed to a content of approximately per cent. moisture.
  • the goods are introduced into a solution of dimethylol-urea of 20 per cent. strength and at a temperature of 50-60 C., which also contains 6 grams each per litre of monoand di-sodium phosphate; pressing to a content of 100 per cent. moisture and drying under tension, so that no folds or creases can be produced, follow.
  • the goods are subjected to the usual condensation at a raised temperature.
  • the cellulose material to be treated is saturated with an emulsion of wax of 3 per cent. strength as specified in Example 1 but with addition of 6 grams each per litre of monoand disodium-phosphate, then pressed or centrifuged, dried under tension and finally treated in a closed vessel for 2 hours at 120 C., under pressure, with vapour of formaldehyde.
  • cellulosic fibers is intended to include fibers of cellulose such as cotton and fibers of cellulose hydrate such as viscose artificial silk.
