Definitions

  • the present invention relates to new textile softening agents.
  • the present invention is based on the unexpected finding that the reaction products of at least 3 mols of formaldehyde with 1 mol of N-alkyl-ureas of N-alkyl-biuret compounds with long chain alkyl radicals, when applied onto textile materials, impart to these materials a soft full handle.
  • the object of the invention is a process for the softening of cellulose fibers or of textile materials consisting of or containing such cellulose fibers, wherein these materials are treated with solutions or dispersions of reaction products of at least 3, preferably 3.2 to 4 mols, of N-alkyl-ureas or N-alikyl-biuret compounds which contain about 14 to 22 carbon atoms in the alkyl radical.
  • reaction products of at least 3, preferably 3.2 to 4 mols, of N-alkyl-ureas or N-alikyl-biuret compounds which contain about 14 to 22 carbon atoms in the alkyl radical.
  • the textile softening agents used according to the invention it is an absolute prerequisite that for their preparation the N-alkyl-urea or N-alkyl-biuret compounds are reacted with at least 3 mols of formaldehyde.
  • the products obtained by the reaction with less than 3 mols of formaldehyde still have hydrophobising properties, but they rapidly lose
  • reaction products used according to the present invention when applied in the form of aqueous dispersions or in the form of solutions in inert organic solvents onto textile materials such as fibers, filaments, fabrics or other products that consist of or contain cellulose, impart onto these materials an agreeable, very soft, flowing and smooth handle.
  • textile materials which may be treated with the softening agents of the present invention may consist of or contain cotton, staple fibers, polynosic fibers or other fibers of regenerated cellulose, or mixture of such fibers with synthetic fibers such as polyamide, polyester, cellulose triacetate and similar fibers.
  • the textile softening agents according to the invention may be prepared by known methods.
  • a fatty amine containing about 14 to 22 carbon atoms for example octadecylamine
  • urea or biuret under separation of ammonia.
  • the condensation is effected generally at temperatures in the range of from about to C.
  • 1 mol of the reaction products obtained is methylolised with at least 3 mols of formaldehyde or formaldehyde yielding substances, for example p-formaldehyde, formaline or trioxane.
  • the methylolation can be effected in aqueous solution, in organic solvents, in the melt or according to other known methods.
  • 3.2 to 4 mols of formaldehyde are used preferably per mol of the N-alkyl-urea compound or of the biuret compound.
  • the use of higher amounts of formaldehyde does not bring further improvements, so that for economical reasons no more than about 4 mols of formaldehyde per mol of the alkyl-ureaor alkyl-biuret-compound are used.
  • N-alkyl-ureaand N-alkyl-biuret compounds there may be used those which correspond to the general formula R NHCO-NH--R in which R, stands for an alkyl radical containing 14 to 22 carbon atoms and R stands for hydrogen or the radical CONH
  • R stands for an alkyl radical containing 14 to 22 carbon atoms
  • R stands for hydrogen or the radical CONH
  • the softening agents of the invention are dissolved in suitable organic solvents or dispersed in water.
  • the aqueous dispersions may be prepared with the aid of nonionic and/ or anionic dispersing agents or stabilized in this manner.
  • the solutions or dispersions of the softening agents may be applied onto the textile material in any desired manner, for example by spraying or impregnation and squeezing.
  • the quantity of softening agents of the invention applied may vary within wide limits and depends on the textile material to be treated and on the softening effect to be obtained. In general, the softening agents are applied onto the textile material in quantities ranging from about 0.01 to 1%, preferably 0.1 to 0.5%, referred to the weight of the textile material.
  • the softening agents of the invention impart onto the textile material treated wash-resistant effects already when used alone and particularly also when used together with an acid catalyst which includes acids and acid-forming substances such as magnesium chloride, zinc chloride, zinc nitrate, diammonium phosphate, ammonium nitrate, and similar compounds.
  • an acid catalyst which includes acids and acid-forming substances such as magnesium chloride, zinc chloride, zinc nitrate, diammonium phosphate, ammonium nitrate, and similar compounds.
  • wash and wear resins for example dimethylol-urea, dimethyloldihydroxyethylene-urea, dimethylol-dihydroxyethyleneurea, dimethylol-propylene-urea and similar compounds, they improve the wet and dry crease resistance, the fastness to rubbing and the resistance to tearing and the tensile strength.
  • softening agents of the invention are their particularly good compatibility with other finishing agents.
  • the finishing bath containing the softening agents of the invention also other auxiliary agents, for example filling and smoothing agents, wetting agents, emulsifiers, water softeners, so-called soil releasers, optical brighteners, catalysts, synthetic resin precondensation products and other additives, without impairment of the original softening effect.
  • the softening agents may be applied from one bath which also contains the additives or from a separate bath, i.e. separately from the additives; in the last case it is advantageous to apply the softening agent at last.
  • the softening agents may also be applied onto fabrics, for example on 3 a foulard or a similar apparatus or by the exhaust method.
  • the fibrous materials may be treated with an engraved or Schreiner calender, and, depending on their composition, at temperatures in the range of from about 20 to 220 C.
  • EXAMPLE 1 A cotton fabric having a weight of 120 g. per square meter was immersed in a bath containing, per liter,
  • the fabric was then squeezed to about 80% of weight increase and dried for 3 minutes at 110 C. The fabric showed then a soft flowing full handle.
  • the fabric was then squeezed to 80% weight increase and dried at 110 C. The residual moisture was 6%. Finally, the fabric was calendered in the usual manner and condensation was effected for 5 minutes at C.
  • the fabric showed a full supple handle and good crease resisting properties.
  • DRY GREASE ANGLE ACCORDING TO GERMAN INDUS- TRIAL STANDARD 53 890 A fabric consisting of 35% of cotton and 65% of polyester fibers was impregnated with a solution containing, per liter 18 g. of 20% aqueous dispersion of a reaction product of N-octadecyl-biuret and formaldehyde, the preparation of which is described hereinafter, and
  • the fabric was squeezed to 60% weight increase and dried at 110 C.
  • the fabric showed an agreeable soft full handle.
  • Process for the softening of textile materials containing cellulose fibers comprising applying to said materials a reaction product of at least 3 mols of formaldehyde and 1 mol of a N-alkyl-ureaor a N-alkyl biuret containing 14 to 22 carbon atoms in the alkyl radical.
