Definitions

  • This invention relates to a washing process for iawlsemimanufactured and finished textile maeri s.
  • the process according to the invention is suited particularly for cleaning very dirty textiles, containing pitch, tar, oil, wax, resins or color. As the process does not injure thematerials, it can be applied alsofor cleaning sensitive animal and vegetable textiles including silk, hair and wool.
  • the pitch referred to involves the colors used for marking animals to prevent the theft thereof and comprising, as a rule, linseed oil, pitch, resins, asphalt; etc., usuallymixed with pigments. Most marking colors contain red lead or colored earths.
  • the suint is a secretion of abnormally functioning sebaceous glands and in most cases due to improper treatment of the animals, though it may also indicate degeneration. With respect .to their-chemical and physical be havior, the most essential constituents of suint are waxes.
  • the invention provides a which impuretextilematerials are'treated with high-boiling chemical compounds which saturate the impurities, soak and partially dissolve them.
  • ethane sulfo acid the ricinoleic and diricinoleic sulfo acids as well as the stearyl alcohol sulfuric acid, the oleylalcohol sulfuric acidand their esters and salts; if the compounds mentioned are not oily, they are used in concentrated aqueous solution.
  • concentrated aqueous solution To this class belong also the sulfonated fats and oils like Turkey red oil and sulionated tallow.
  • the corresponding phosphoric acids or phosphoric acid esters may also be used, especially in the form of their acid salts or acid esters.
  • the compounds as such or in the form of their concentrated aqueous solutions possess a high, penetrating capacity, so that they penetrate the impurities, soften them and dissolve them partly. After this soaking step, the high-boiling chemical compounds together with the impurities are removed from the fibers, preferably and as much as possible by mechanical means, e. .g.,
  • the substances concerned may themselves act as emulsifiers for aqueous suspensions like the sulfo acids, the sulfuric acid esters, the. phosphoric acids and esters,
  • alkaline washing'waters are used, which is absolutely necessary if free carboxylic acids have been employed,-as the latter, unlike their salts, the soaps, possess only slight emulsifying properties.
  • the impurities are thus removed from the textiles and .remain as suspension in water while the compounds used for To simplify the process the squeezed or hydro-extracted material may be placed di rectly in the usual washing liquors which are slightly alkaline and normal stuff.
  • the substances used for soaking can be recovered-from the finish it together with the washing liquors either by salting out or adding mineral acids.
  • the separated compound is purified in the usual way,
  • Example 1 weight of commercial olein After five to twenty hours, according to temperatur the impurities can be ground with the fingers. is then'removed by squeezing or hydro-extracting, and the wool placed in a weakly alkaline washing bath wherein the washing process is c. nple'ted in the usual manner at 50 C. By adding sulfuric acid to the washing water the olein can be recovered and used for the same process after having been purified by one of the customary methods, e. g. filtration.
  • the customary methods e. g. filtration.
  • Example 2 Example 3 Wool containing waxlike suint and picked out of normally washed'lots is saturated with Turkey red oil (50% quality), which requires about 2 or 3 The excess olein.
  • Example 4 Raw cotton containing resinous or color impurities is saturated with twice the amount of ground nut oil acid. lifter the cotton has remained therein for 20 hours, it is squeezed and placed in a bath of 5% potash lye, whereupon it is hydro-extracted and Washed in an alkaline washing liquor until the washing process is completed.
  • the process of removing pitch from a textile material comprising steeping the material in a liquid higher fatty acid softener for pitch of a quantity exceeding the material in weightvuntil the pitch has become friable when the material is rubbed between fingers, removing so much of theaoid as can be mechanically removed, rendering the remaining acid water-soluble by introducing an aqueous alkaline solution to saponify the same, and then washing off the saponified acid together with the pitch emulsified therein.
