Definitions

  • This invention relates to the finishing of woolen textiles such as woolen yarns and cloth, raw wool and the like, as well as Wool-containing textiles in which the wool is blended with other fibres such as the cellulosic fibres.
  • the invention includes the application to woolen textilesof novel finishing compositions capable of imparting theretocombined shrinkage control and insecticidal properties.
  • process of our invention produces washable woolen textiles that retain their dimension stability and insecticidal properties even after they have'been laundered a number of times.
  • any desired quantities of alkylated methylol melamine and of fluoride may be applied by the process of our invention.
  • the alkylated methylol melamine is applied in quantities of about 2-15%, based on the dry weight of the woolen textiles, the maximum quantity being about 20%.
  • the fluoride is applied in amounts of about 05-10%, based on the dry weight of the textiles.
  • the fluoride may be soluble in the textile-finishing solution, as when sodium or potassium fluoride or triethanolamine silicofiuoride is used, or it may be a waterinsoluble fluoride such as calcium, barium or strontium fluoride or silicofluoride.
  • Suitable alkylated methylol melamines are ethylated or ethanol-reacted trimethylol melamine and butylated trimethylol melamine, preferably applied from aqueous solutions containing organic solvents, but the preferred resinous material is water-soluble methylated methylol melamine. This material is prepared by the following process. I
  • dried powder is alkylated by admixture with twice its Weight of 95% methanol containing 0.5% of oxalic acid crystals, based on the weight of the methylol melamine.
  • the mixture is heated to 70 C. and held at this temperature for approximately minutes, or until a clear solution is obtained, whereupon it is immediately neutralized by the addition of sufiicient sodium hydroxide solution to raise the pH to approxi-
  • the neutralized reaction mixture is then evaporated to 80% solids under reduced pressure so that the temperature does not rise above 50 C.
  • the textile-finishing compositions of the present invention contain the alkylated methylol melamine dissolved therein to a strength roughly equivalent to the percent of resin desired in the textiles together with the amonut of fluoride desired for insecticidal purposes.
  • a watersoluble fluoride such as triethanclamine silicofiuoride
  • water-insoluble fluorides are preferably reduced to fine-particle size, as by precipitation from soluble fluorides or by grinding, and are added to the alkylated melamine resin solution as an aqueous suspension.
  • a curing accelerator for the alkylated methylol melamine such, for example, as diammonium hydrogen phosphate should be used in amounts of about 3% based on the weight of the alkylated methylol melamine.
  • Water-soluble fluorides such as triethanolamine silicoiiuoride can be used to replace this or other curing accelerators, since we have found that they will bring about an accelerated curing of the resin without interfering in any way with their insecticidal properties. This is true even when the impregnating bath is made alkaline with a volatile base such as ammonia, triethanolamine and the like.
  • the combined insecticidal and curing accelerating properties of the water-soluble fluorides and silicofluorides therefore, constitute another important advantage of the invention.
  • a textile-finishing bath was prepared by adding 15 cc. of triethanclamine silicofluoride dissolved in about 150 cc. of water to a solution of 45 grams of methylated methylol melamine, prepared as described above, in 140 cc. of water.
  • the washed and unwashed treated pieces and the washed and unwashed untreated pieces were then exposed to black carpet beetle larvae for two weeks, using the method of damage evaluation based on the corrected weight of droppings as described in Soap and Sanitary Chemicals, August 1942 (vol. 18, No. 8), pages -99.
  • the unwashed, untreated piece showed 10.5 mgs. of droppings, whereas the unwashed, treated pieces showed 0.0 mg. of droppings.
  • the washed, untreated piece showed 21.4 mgs. of droppings, whereas the washed, treated piece showed only 2.6 mgs. of droppings.
  • Example 2 Other fluorides were suspended in 13 aqueous solutions of methylated methylol melamine which were then applied to wool flannnel in amounts of of its weight so that the impregnated cloth contained 13% of resin and the quantity of insecticide indicated below. The treated cloth was then evaluated by the methods described in Example 1 with the following results:
