Definitions

  • This invention relates to the treatment of woolen textile materials with di-pentachlorphenyl-mono-hydrogen phosphate for protecting them against biological attack.
  • chlorinated phenols and particularly pentachlorphenol when applied to textile materials, possess the power to a high degree of protecting such materials from attack by moulds, bacteria and biting insects.
  • chlorinated phenols also possess undesirable properties from the point of view of the textile technologist to varying degree, particularly solubility in water and volatility which are large for the orders of magnitude involved, although these undesirable properties are least developed in pentachlorphenol.
  • the substances which consequently are employed in accordance with the present invention are the phosphates of pentachlorphenol, in particular the di-pentachlorphenyl mono-hydrogen phosphate which as far as can be ascertained has the composition P Ct.Ol5O O and which it is believed has not been previously prepared.
  • the customary method of preparing such compounds is to heat the phenol with phosphorous oxychloride but in the case of pentachlorphenol, the customary method of boiling the reagents together yields a very poor resultat most a few per cent of the theory. The reaction does not begin to take place at temperatures below 180 C.
  • the sodium compound forms a fine white power which disperses spontaneously in water or dilute alkali.
  • Woolen goods can be dyed with the suspension of the compound used, either per se or together with dyestufi's in the presence of the customary additions in the usual manner.
  • Di pentachlorphenyl-mono-hydrogen phosphate is substantive to wool and compatible with the usual dyestuffs.
  • the goods may be padded through a dispersion in water under either acid, neutral or alkaline conditions, squeezed and dried, although the dyeing method is preferred.
  • the phosphates can be applied in non-aqueous media.
  • the acid phosphate from methylated spirits solution. Textiles containing as little as 0.5 per cent of the acid phosphate are immune from the attack of even the carpet beetle, Attagenus pieeus and retain this immunity after repeated washings with soap 3 or soap and soda or after frequent commercial dry cleaning Operations.
  • a method for the protection of a woolen textile material against biological attack which comprises impregnating said textile with di-pentachlorphenyl-monohydrogen phosphate.
