Definitions

  • Our present invention relates to artificial filaments capable of being dyed with wool and chrome dyestuffs.
  • This invention is based on the observation that resinous condensation products obtainable by the reaction between cyanamide and acetaldehyde or any higher aldehyde but not formaldehyde are suitable for improving the dyeing capacity of the filaments produced from spinning solutions. If one of these products in solution or fine dispersion is added to the spinning solution, it remains in the thread produced from the solution and imparts to the thread a capacity for being dyed well and fast by means of acid wool and chrome dyestuffs. By the correct proportioning of the condensation product from cyanamide and aldehyde, fibers are produced which, in respect of their capacity for being dyed with acid wool dyestuffs, are not inferior to wool fibers.
  • processes for spinning the solution are those in which no acid precipitating bath is used, for instance that described in the U. S. Patent No. 2,082,814, as well as the acid spinning processes.
  • the condensation p oducts may be made in a manner similar to tha in which the condensation products from cyanimide and formaldehyde are made (U. S. Patents Nos. 1,791,433 and 1,791,434).
  • the condensation products from cyanamide and acetaldehyde are in part soluble in alcohol and in part insoluble. They are introduced either in solution, for example in alcohol, or undissolved in finely subdivided condition into the spinning solution in the course of its manufacture.
  • Compounds which are not of themselves soluble in alcohol may, if desired, be made soluble in alcohol by dissolution in an acid and subsequent precipitation by alkali.
  • the reprecipitated product is especially useful as an addition to spinning solutions. Both the products which are soluble in alcohol as well as those which are insoluble are preferably spun into a neutral spinning bath and afterwards dyed in a neutral bath with acid dyestuffs, since they are soluble in acids.
  • the product of the reaction of cyanamide with for instance isohexylaldehyde is a resinous feebly yellow substance which is soluble in alcohol but practically insoluble in water, alkalis and acids. In consequence it may be used in the xanthate spinning process and in the acid spinning process and yields a fibrous material which dyes like wool in an acid bath. It is important to attain a thorough emulsification of the body in the viscose.
