Definitions

  • an alkaline agent there may be used an organic base as for example: pyridine, piperidine andsimilar substances, or an inorganic base such as potassium hydroxide or a mixture of inorganic and/or organic bases. Any alkaline agent may be used which is soluble in the selected organic solvent.
  • the system comprising solvent agent (pure or mixture) and alkaline agent may be applied to the textile material to be treated using the common means, that is:
  • the process according to the invention may be appliedwith devices of common type, provided that metals and joints have a nature able to resist the solvents and that the conventional convenient measures are taken with regard to solvent vapors, so as to catch the vapor for a distillation recovery, and to maintain staff safety and buildings salubrity.
  • the critical temperature from which this green coloration is obtained on a nondesized fabric is C.; this polymer is made nonsoluble by the heat necessarily applied for fiber thermal fixing. Consequently it is desirable to test, if, after desizing, there remains any polyacrylic acid which may be made nonsoluble by fixing treatment. From this point of view it has been discovered that by contacting the fabric to be tested with series of studs heated to temperatures having between them a gradation from 171 C. up to the upper temperature at which such treatment is achieved, it is possible to obtain a valuable quotation to measure desizing degree.
  • the fabric to be tested is a polyamide 6- 6, which will subsequently be thermofixed at 210 C. and if the gradual series of studs has 4 of them between 171 C. and 213 C., for example l76l83-193-204, the number 1 can be assigned to the stud at 171, 2 to 176, 3 to 183, 4 to 193, 5 to 204 and 6 to 213; and the desizing degree, quoted as numbers l to 6, will be obtained when Identex 11 is applied to a textile material, the green color appearing on the surface having been in contact with studs, 1,2,3,4,5 or 6 during equal times and pressures.
  • EXAMPLE 1 The experimentation is made on a polyamide 6-6 taffeta of 95 g./m. and the warp of which has a polyacrylic acid sizing at the rate of l to 2 percent of warp weight and the weft of which has a greasing with emulsified mineral oil at the rate of 1 percent of oil with regard to fabric weight.
  • the dry unbleached fabric is passed at the speed of 100 m.lmin. in a pad with two rolls giving a squeezing ratio of 65 percent in a bath at 18 C. composed per 100 liters of:
  • the vat has at its outlet a squeeze device to remove solvent up to 80 percent. Then the fabric passes in a short stenter comprising a vaporization chamber maintained at the temperature necessary for solvent removing, provided with a device for solvent vapors catching and a thermofixing chamber maintained at 210; the total duration of passage through the stenter does not exceed 2 min.
  • the fabric wound at the stenter outlet is adapted for dyeing directly Desizing degree 18 controlled on a strip taken from the storage roll after the 24 hr. storage.
  • This strip is rinsed hastily in a beaker containing tetrachlorethylene brought to 80 C., then dried, contacted during 1 minute with heated studs of an ADAM thermotest and at last immersed during 1 minute in the reagent ldentex 11" at 15C., then washed and rinsed.
  • Desizing degree quotation is 6 consequently the degree of desizing is excellent.
  • EXAMPLE 2 A polyamide-6 linen of 80 g./m. is wound in a closedjigger in which is introduced a 10 percent solution of piperidine in trichlorethylene.
  • the roll is extracted from jigger and stored during 24 hr. at room temperature while maintaining it in slow rotation.
  • the roll is circulated in a second closed jigger containing a trichlorinated ethylene bath maintained at 80. Only one passage is made at maximum speed.
  • the jigger has at its outlet a squeezing device followed by a short vaporization chamber with solvent vapor recovery, and winding at the outlet of the fabric preparatory for printing in turn followed with a thermal fixing.
  • control achieved according to the same modalities as in example 1 is limited to quotation 3 for desizing, because the maximal temperature for polyamide 6 does not exceed 180 C. This is good desizing under the required conditions.
  • Process for degreasing and desizing textile fibers and threads which are protected by a coating of mineral oil and polyacrylic acid or its derivatives which comprises dissolving said coating compounds in a anhydrous medium consisting essentially of an organic solvent or solvent mixture selected from the group consisting of trichlorethylene, carbon tetrachloride, perchlorethylene, trifluorotrichloroethane, ethylene bromide, methanol, isopropanol, isobutanol and azeotrope isopropanol/tetrachlorethylene, said solvent containing dissolved therein an organic alkaline agent selected from the group consisting of potassium hydroxyde, pyridine, and piperidine;
