Definitions

  • ABSTRACT Aqueous mercerizing solutions containing an alkali metal hydroxide and an alkali metal salt of a phosphinic acid of the formula in which R, is methyl or ethyl and R is an aliphatic hydrocarbon radical of 4 to 12 carbon atoms, and the use of these solutions for mercerizing cellulosic fibrous materials.
  • FIG. 1 1
  • the present invention relates to aqueous solutions containing alkaline agents and phosphinic acids for mercerizing purposes.
  • alkali metal hydroxide solutions having a strength sufficient to meet certain requirements are allowed to act on the material.
  • alkaline solution it is necessary to have the material soaked with alkaline solution as quickly and uniformly as possible.
  • wetting agents are added to the solutions while making sure that these are readily soluble in the lye, bring about a maximum shrinkage rate of the cellulosic fiber within the shortest possible time and remain in solution even after the lyes have been stored for a prolonged period of time.
  • alkyl sulfates, alkane sulfonates, alkyl-aryl sulfonates, lignin sulfonic acids, sulfated terpene derivatives, alkylated naphthalene sulfonic acids and analogous compounds can be used as wetting agents in mercerizing liquors.
  • German Auslegeschrift No. 1,014,067 discloses the application of mixtures of such mono and polysulfonic acids or salts thereof in mercerizing baths. Those compounds have been obtained by sulfo-chlorination of aliphatic or cycloaliphatic hydrocarbons having 10 to 20 carbon atoms.
  • the wetting agents are generally combined with other adjuvants which disperse and keep in suspension the products which have been dissolved off the fiber during the mercerizing operation, for example cellulose degradation compounds or remaining sizes.
  • these adjuvants have a synergistic effect on the wetting power of the wetting agents which are known to be low-molecular-weight alcohols, for example isopropanol, butanols, alkanol-amines, glycols and derivatives thereof, polyglycols and other compounds disclosed, inter alia, in Lindner Tenside, Textilosstoff, Waschrohstoffe", vol. II, 1964, pages 1476 to 1478.
  • wetting agents hitherto used for mercerizing liquors do not meet all the practical requirements at the same time. They either wet the fiber very rapidly while having to be used, however, in high concentrations or they are not stable in the alkaline solutions for a sufficiently long time, lose their effectiveness or precipitate. in many cases, moreover, their heavy foaming is troublesome.
  • This invention now relates to aqueous solutions for mercerizing and treating cellulosic fibers and goods made therefrom with lyes, which have an excellent wetting effect and a high stability and contain, in addition to about l to 400 g/l of sodium, potassium or lithium hydroxide or mixtures of these alkaline agents, as wetting agents, from 0.] to g/l of phosphinic acids of the general formula in which R, stands for a methyl or ethyl group and R for an aliphatic linear, branched or cyclic hydrocarbon radical having 4 to 12 carbon atoms, preferably 6 to 10 carbon atoms, in the form of their alkali metal salts as essential ingredients.
  • the phosphinic acids or the alkali metal salts thereof to be used as wetting agents according to the invention may be prepared according to various methods, for ex ample by the known reaction of sodium salt of methane-phosphonic acid monoethyl ester with Grignard compounds (cf. K. A. Petrov et, al., Z. obsc. Chim. 30 1964-8 (1960); C.A. 55, 6363b (l96l).
  • the process disclosed in French Patent No. 7,045,l30 and German Offenlegungsschrift No. 2,l00,779 is especially preferred, according to which dialkyl phosphinic acid alkyl esters of the general formula R OR 0 ii f" a in which R and R are defined as above.
  • phosphonous acid alkyl esters suitable for this reaction there are mentioned, for example, methane-phosphonous acid methyl ester, methanephosphonous acid ethyl ester, octane-phosphonous acid ethyl ester.
  • the salts or free acids thereof may be prepared from the dialkyl phosphinic acid esters by hydrolysis according to known methods, advantageously by an alkaline saponi fication.
  • the solutions of the invention may, however, also be prepared using the dialkyl phosphinic acid esters or the free acids. thereof.
  • the phosphinic acids and the salts thereof to be used according to the invention are readily soluble in water and give limpid solutions. In an alkaline medium, they have such an excellent wetting power that they can be used in lower amounts than conventional wetting agents.
  • the concentrations used in the mercerizing solutions are between O.l and 5 g/l, which means not only a very economical application of the compounds but also hardly any pollution of waste water.
  • the phosphinic acids and the salts thereof do practically not foam in the alkaline solutions. They are preferably used for mercerizing liquors containing a high amount of about to 300 g, preferably 200 to 250 g of sodium-, potassiumor lithium hydroxide or mixtures thereof per liter of liquor.
