Definitions

  • SHEET 1 Shrinkage 0 1'0 20 30 is 60 7'5 950 sec m PM.
  • PATENTEDJUH 17 1975 from/sec Shrinkage Rate 1 MERCERIZING SOLUTIONS The present invention relates to aqueous solution containing alkaline agents and phosphonic acid derivatives for mercerizing purposes.
  • alkali metal hydroxide solutions having a strength sufficient to meet certain requirements are allowed to act on the material.
  • 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 (and lye-treating) baths. Those compounds have been obtained by sulfo-chlorination of aliphatic or cycloaliphatic hydrocarbons having to 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. 11, 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 trouble some.
  • 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 10 to 400 g/l of sodium-, potassiumor lithium hydroxide or mixtures of these alkaline agents, as wetting agents.
  • Dialkyl phosphites to be used for the reaction are, for example, dimethyl phosphite, diethyl phosphite, diisopropyl phosphite, di-n-hexyl phosphite, di-Z-ethylhexyl phosphite. decyl-isobutyl phosphite, propyltetradecyl phosphite, dioctadecyl phosphite, di-eicosyl phosphite and di-docosyl phosphite.
  • the salts and free acids thereof may be prepared from the alkane phosphonic acid diesters by hydrolysis according to known methods.
  • the phosphonic 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 0.1 and 5 g/l, preferably between 1 and 5 g/l, which means not only a very economical application of the compounds but also hardly any pollution of waste water.
  • the phosphonic acid derivatives 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.
  • composition of the mercerizing solutions for which the phosphonic acid derivatives are used according to the invention, is known; they generally contain 10 to 400 g of sodium-, potassiumor lithium hydroxide or mixtures therof per liter of liquor and, where required, further usual adjuvants.
  • the solutions are used at temperatures of from about 0 to 25C.
  • further additives see Lindner Tenside, Textilosstoff, Waschrohstoffe," vol, II, 1964, pages 1476 to 1478, and
  • the mercerizing solutions of the invention are used in known manner for treating cellulosic fibers and goods made therefrom as well as textile material containing cellulosic fibers in addition to synthetic fibers.
  • All the tested mercerizing liquors contained 220 g of sodium hydroxide per liter and, in addition, the following wetting agents and adjuvants:
  • FIG. I shows the values of shrinkage as a function of time using liquors Nos. 1, 5 and 6.
  • FIG, II shows the corresponding values of shrinkage speed as a function of time.
  • An aqueous mercerizing solution essentially consisting of 10 to 400 g/l of sodium-, potassiumor lithium hydroxide or a mixture thereof, and 0.1 to 5 g/l of phosphonic acid derivative of the formula in which R stands for an aliphatic linear, branched or cyclic hydrocarbon radical having 6 to 10 carbon atoms, and X and Y which may be identical or different, each stands for hydrogen, sodium, potassium or an aliphatic linear or branched hydrocarbon radical having 1 to 4 carbon atoms.
  • Liquors Nos. 1 and 1(a) had the same composition; liquor No. 1(a) was, however, allowed to stand for 24 hours prior to its use for the tests.
  • test results are compiled in the following Table.
  • a process for treating with lyes and mercerizing cellulosic fibrous material which comprises treating the fibrous material with an aqueous alkaline merceriz- 5 ing solution containing, as a wetting agent 0.1 to 5 g/l of a phosphonic acid derivative of the formula Shrinkage Shrinkage speed Time in mm in mm per sec. sec.
