Definitions

  • Wool that has been felt-proofed and dyed according to the Hercosett process has low wet fastness to the dyeing.
  • these dyeings must have a high level of wet fastness. It is therefore known to improve the wet fastness of dyed wool, which is felt-proof after the Hercosett process, with the help of an aftertreatment.
  • Such methods are known for example from DT-OS-2 801 535 and DE-OS-2 949 510.
  • the object of the invention is to provide products for the felt-proof finishing of wool which are easier to use in practice than the known resins and which moreover are more effective than the known resins.
  • a further object of the invention is the production of wool that has been treated and dyed to be felt-proof, the dyeing already having such a high wet fastness that the otherwise customary aftertreatment can be dispensed with.
  • the wool which is treated according to the process according to the invention can be in the form of flake, sliver, yarn, woven or knitted fabric. As in the Hercosett process, it is chlorinated in a first treatment stage. As with this, it is essential that the pH of the chlorine treatment bath be below 4. A pH of 0.5 to 3 is preferably set here.
  • a chlorinating agent e.g. B. water-soluble hypochiorites, such as sodium hypochlorite, gaseous chlorine which is introduced into the water, or chlorine-releasing agents, such as alkali metal dichloroisocyanurates, can be used.
  • the devices for the first treatment stage can be, for example, a Lisseuse bath for combing, a Leviathan bath for flake or a foulard for piece goods.
  • the chlorination can also be carried out batchwise in a dyeing apparatus in a known manner. At most, a strong liquor circulation or a strong agitation of the wool in the bathroom is necessary, so that a uniform chlorination of the wool is ensured at the proposed low pH.
  • the chlorination temperature is usually below 30 ° C.
  • the chlorination is carried out according to the prior art to such an extent that the wool reacts with 0.5 to 2 percent by weight of active chlorine.
  • the excess chlorine is removed in a known manner using reducing agents.
  • the chlorinated wool is treated in a bath with aqueous solutions of sodium sulfite, sodium hydrogen sulfite, sodium dithionite, thiourea dioxide or zinc hydroximethanesulfinate at temperatures from 20 to 90, preferably from 30 to 80 ° C.
  • reducing agents After treating the chlorinated wool with reducing agents, it is washed one or more times with water, preferably with warm water, each squeezed and dried.
  • the wool treated in this way is dried at temperatures up to 150, preferably 60 to 150 ° C.
  • Suitable dyes are, for example, acid dyes, 1: 1 and 1: 2 metal complex dyes, post-chromating dyes and reactive dyes. These dyes are those which are usually used for dyeing wool. Their structure can be found in the color index; they are commercially available. Methods for dyeing wool are also state of the art, so that there is no need to go into them at this point.
  • the dyeing is carried out mainly in an aqueous medium at temperatures from 95 to 110 ° C or in the block-cold dwell process.
  • Bases such as sodium hydroxide solution, potassium hydroxide solution, sodium carbonate, calcium oxide, calcium hydroxide, barium oxide or barium hydroxide are optionally used to adjust the pH during the condensation. If the compounds of group (a) are used in excess in the condensation, a pH in the alkaline range is established due to the basicity of these compounds.
  • the condensation is carried out in aqueous solution at a solids content of the solution of 20 to 60 wt .-% and temperatures of 60 to 100 ° C.
  • the water-soluble non-quaternized condensation products have a viscosity of at least 500 mPas in 45% aqueous solution at a temperature of 20 ° C. Particularly effective condensation products are obtained by condensing piperazine with epichlorohydrin or ethylene chloride and then quaternizing with benzyl chloride. Such products are known.
  • benzyl chloride For the oxygenation of the condensation products from components (a) and (b), 0.15 to 1.0, preferably 0.4 to 0.75, mol of benzyl chloride is used per equivalent of nitrogen in component (a).
  • the quaternization is preferably carried out in an aqueous medium at temperatures from 60 to 100.degree. Both the condensation reaction and the quaternization of the condensation products can be carried out at temperatures above 100 ° C. under pressure. This results in shorter response times.
  • the aqueous solutions of the quaternized or partially quaternized condensation products can be used directly for the treatment of the chlorinated and optionally colored wool.
  • the treatment of the wool with the quaternary products can be carried out batchwise in a dyeing machine or continuously in a lisseuse.
  • the temperature of the polymer solution is up to 100 ° C. and is preferably in the range from 30 to 50 ° C.
  • the pH of the resin solution is adjusted to 4 to 10. It is preferred to work in the pH range 7 to 8.
  • Based on the weight of the wool 0.5 to 3, preferably 0.7 to 1.5% by weight of the quaternary condensation products described above are applied.
  • the chlorinated, optionally colored and provided with a resin layer as a quaternary product is optionally rinsed and optionally equipped with softening agents.
  • the treatment of the wool with plasticizers can - provided the plasticizer is compatible with the quaternary condensation product - also be carried out together with the polymer treatment.
  • the wool treated in this way is mechanically dewatered, e.g. B. by squeezing, and dried in the temperature range of 80 to 150 ° C.
  • the quaternary products to be used according to the invention only result in good felt-proofing of the wool if the chlorination step is carried out at pH values below 4.
  • the chlorination step is carried out at pH values below 4.
  • only about half of the amount of polymer required for the same effect in the Hercosett process is required by the process according to the invention.
  • the wool can not only be made felt-proof, but can also be dyed within this process sequence. The dyeing always follows after the chlorination of the wool and before the application of the cationic polycondensate to the wool.
  • the parts given in the examples are parts by weight, the percentages relate to the weight of the wool and, in the case of the polymeric products, to the anhydrous active substance.
  • the viscosities of the condensation products were measured using a rotary viscometer (Haake, RV 3).
  • 332 parts of the condensation product were mixed with 7130 parts of 50% sodium hydroxide solution and 248 parts of propanediol and 252 parts of benzyl chloride were added at 50 to 70 ° C. in the course of 40 minutes. After 5.5 hours at 70 to 80 ° C the benzylation was complete. It was diluted to an active ingredient content of 22 with 784 parts of water.
  • the clear, stable solution of the condensation product 3 had a pH of 4.4, a viscosity of 60 mPas (20 ° C.) and a chloride content of 1.6 mMollg. The drug content was 22%.
  • the tapes were then rinsed in a third bath with water heated to a temperature of 40 ° C and then dried in the dryer at a temperature of 95 ° C to a residual moisture content of 10%.
  • the wool was then evened out on a needle bar section and formed into wraps.
  • the wool thus pretreated was then dyed in a dyeing machine with an aqueous liquor containing 3 of the blue acid dye of Color Index No. 15,707.
  • the wool sliver belts were then continuously rinsed in a washing machine at a speed of 16 m / min in a bath with water at a temperature of 20 ° C. and passed continuously through a second bath containing a 5% aqueous solution of the condensation product 1 contained, had a pH of 7.5 and a temperature of 40 ° C.
  • the polymer coating was 1%.
  • the wool sliver belts were then rinsed in a third bath with water at a temperature of 40 ° C. and dried in a dryer at 95 ° C. to a residual moisture content of 10%.
  • Example 1 it is possible according to the process according to the invention (Example 1) to achieve the same excellent felt resistance as with the prior art (comparative example 1) with half the amount of polymers and with considerably less treatment aggregation.
  • the goods dyed and felt-proof finished according to Comparative Example 1 do not have the fastness properties that the IWS requires for the wool seal. Post-treatment would be required for this.
  • the goods dyed according to Example 1 meet the requirements that the IWS places on the wash and sweat fastness of dyeings.
  • Woolen drawstring tapes with a thickness of 25 g / m and a wool fineness of 20 microns were produced according to the "Kroy-Deepin method" (cf. Wool Science Review 55, 35 (1978)) at a pH of 1.2 and a temperature chlorinated at 15 ° C. The active chlorine absorption of the wool was 1.5%.
  • the woolen drawstrings were then dyed with an aqueous liquor containing 4.5% of the 1: 2 chlorine complex of the black acid dye C.I. 15711 included. The temperature during the dyeing was 100 ° C., the dyeing time was 60 minutes. After dyeing was completed, cold water was added to the dye bath until the temperature of the bath had cooled to 40 ° C. Then 1.2% of the condensation product 2 was added and the combing belts were treated in this liquor at a pH of 8-15 minutes. The goods were then rinsed, dried, processed into knitting samples and checked. The results are shown in Table 2.
  • Example 2 The procedure is initially as given in Example 2, the wool sliver is chlorinated and then 2% of a polyamidoamine resin crosslinked with epichlorohydrin is applied by the process of the prior art.
  • the wool comb is then - as in Example 2 - dyed with an aqueous liquor which contains 4.5% of the 1: 2 chromium complex of the black acid dye CI 15 711.
  • the ridge was then dried after rinsing and passing through a lisseuse, knitted into knitting samples and checked. The results are shown in Table 2. Only the treatment according to the invention leads at the same time to good felt resistance and good color fastness.
