Definitions

  • the invention relates to a process for dyeing synthetic, hydrophobic fiber materials with organophilic dyes free of sulfonic acid groups by the extraction method.
  • the colorings often leave something to be desired in terms of rub fastness and levelness.
  • Example 18b of DE-A-2 247 568 alone a Soxhlet apparatus is described in which the colorant is deposited in a glass fiber sleeve which is de facto flowed through by the cold water condensed on the reflux condenser of the apparatus.
  • the extraction process known per se can be carried out in a simple manner, i.e. can be used for dyeing hydrophobic fibers without using special preparations and while observing economically interesting dyeing times, if the depot is loaded with a dye with a minimum solubility in water of 20 mg / l at 1'30 ° C and flowed through by an aqueous dye liquor at dyeing temperature leaves that is free of emulsifiers and dispersants.
  • the flow through the fleet can take place directly or indirectly in a so-called by-pass.
  • Suitable dyes for carrying out the process are described in detail and comprehensively in the patent literature or - in the case of commercial products - are listed in the Color Index. They can belong to a wide variety of chromophoric systems. Examples include dyes from the azo, anthraquinone, quinophthalone, perinone and methine series, and organophilic optical brighteners.
  • Suitable dyes are, in particular, those which are more than 50 mg / l, in particular 100 mg / l, soluble in the aqueous liquor at 130 ° C.
  • solubility in water is determined by methods known per se, for example by taking a measured amount of dye solution at 130 ° C. from a suitable apparatus, as described, for example, in Melliand Textile Reports 11, (1969), page 1342, using a sample with Water-miscible polar, organic solvents (eg dimethylformamide) are diluted and the dye content therein is determined photometrically.
  • dyes which carry a hydrophilizing substituent group R such as -COOH, -COOV, -O-COOV, -O-CONHV, -SO 2 -V, -SO 2 -OV, -NH-SO2-V, - (alkylene-O-) n V ', -CH 2 -CH 2 -CN, where V is optionally substituted alkyl, aralkyl or aryl, V, and V2 is hydrogen or optionally substituted alkyl, aralkyl or aryl, V 'is V, or acyl and n are numbers from 1-8.
  • R hydrophilizing substituent group R
  • the alkyl and alkoxy radicals mentioned above in any context preferably have 1-4 C atoms and can be or auxiliary chemistry usual substituents (eg OH, CN, Cl, NO 2 , F, Br, alkoxycarbonyl or alkoxy), with the exception of ionic radicals (except COOH) in the dye radicals.
  • Suitable aryl or aryloxy radicals are naphthalene and especially benzene radicals, which may be substituted by alkyl, alkoxy, CI, F, Br, NO 2 , alkoxycarbonyl, CF 3 , CN or COOH subst. are.
  • Suitable hetaryl radicals are pyridyl, thienyl, furyl, quinolinyl, thiazolyl, thiadiazolyl and pyrazolyl.
  • Suitable alkylene radicals preferably have 2-10 C atoms in the chain, which can optionally be substituted by alkyl, aryl, aralkyl or COOH. -C2H4- is preferred.
  • Suitable arylene residues are naphthylene and especially phenyl residues, e.g. by alkyl or aryl subst. could be.
  • Suitable bridge members are O, S, CO, alkylene, phenylene and others.
  • Suitable derivatives of the carboxyl group are nitriles, carboxamides, alkyl esters, acid anhydrides and imides.
  • Very particularly preferred polyether dyes are those of the formula IX in which at least one of the radicals R 1 -R 7 represents the radical - (C 2 H 4 O) m X, which is attached to the azobenzene molecule directly or via a bridge, for example O or CO is bound and m is 2-5.
  • the dyes are used in the form of powder or granules or - according to a preferred process variant - as tablets. If appropriate, these molds can contain customary auxiliaries such as dispersants, mold release agents, blending agents, etc. An intensive grinding process, however, is not necessary when manufacturing these preparations.
  • the dyeings can be carried out at the boiling point of the aqueous dye liquor or - preferably - in closed dyeing systems at temperatures of approx. 130 ° C.
  • the fiber material is dyed in a weakly acidic to weakly alkaline bath, advantageously at a pH of 3.5-6; the liquor ratio can vary between 1: 3 to 1:40, preferably in the range 1: 8 to 1:20.
  • auxiliary agents with a known effect can be added to the dye liquor - for example phenol derivatives such as o-phenylphenol, methyl salicylic acid, chlorinated aromatic hydrocarbons such as o-dichlorobenzene or methylnaphthalenes or 2,2'-dinaphthylsulfonic acid sodium.
  • phenol derivatives such as o-phenylphenol, methyl salicylic acid, chlorinated aromatic hydrocarbons such as o-dichlorobenzene or methylnaphthalenes or 2,2'-dinaphthylsulfonic acid sodium.
  • the amounts of auxiliary agents which are added vary between 0.1 g / l and 4 g / l.
  • aqueous moths which apart from the specified auxiliaries can only contain the substances necessary for pH regulation, are generally free of organic solvents.
  • structures made of polyesters, cellulose acetates or polyamides are suitable as textile materials, these fibers being able to be used in a mixture with one another or together with natural fibers such as wool or cotton.
  • the present process for dyeing the synthetic fibers can be combined with dyeing operations for dyeing the native fiber components.
  • dye mixtures are also used to dye a type of fiber using the dyeing process according to the invention.
  • 500 parts of polyester yarn are dyed in the form of a bobbin in a bobbin dyeing machine with a dye depot; for this purpose, the depot with 9 parts of a coarsely comminuted, unformed dye of the formula CI Disp. Yellow 42 is charged, the system is filled with water without any further additives and the aqueous liquor is quickly heated to 130 ° C.
  • the circulation through the winding body takes place alternately from 3 minutes or 5 minutes from the inside to the outside and vice versa.
  • the water flow can be directed through the depot immediately, ie at the beginning of the heating phase or only after reaching 100 or 130 ° C. After a dyeing time of 45 minutes at 130 ° C, the dye is completely detached from the depot and applied to the polyester cheese.
  • the dyebath is drained after cooling to approx. 80 ° C. After a short rinsing passage, a yellow color in 1/1 standard depth of excellent levelness is obtained, which in no way differs in color depth and hue from a reductive aftertreated 6% coloration, which was produced with formed commercial dye.
  • aqueous liquor used for pH regulation e.g. 1 g / l sodium acetate and 1 ml / l acetic acid 30 ° / oig added, so 'colorations are achieved with the same depth, brilliance and fastness.
  • polyester piece goods 200 parts are wound onto a material carrier and used in the cross-winder dyeing unit described above.
  • the 'depot is made with 1.1 parts of a tabletted dye consisting of 95% of the dye of the formula (CI Disp.-Violet 50) and 5% binding or separating agent (produced on a rotary machine or eccentric tablet press with a pressure of 900-1000 atmospheres) and the system is filled with water.
  • the liquor is brought to 130 ° C. as quickly as possible and dyed at this temperature for 50 minutes. After cooling and draining the liquor and rinsing, a red-violet color in 1/1 RTT is obtained, which does not differ from a red. post-treated coloring, which is obtained with finished dye if the amounts of pure dye used are the same for both dyeings.
