Definitions

  • the dyeing of textile materials can be carried out according to known methods in that the textile material is drawn out with a dyeing liquor containing reactive dye, usually at elevated temperature and in most commercially available reactive dye types in the presence of alkali, or continuous or discontinuous processes, such as the so-called pad-steam process, or the cold retention process can be used.
  • a dyeing liquor containing reactive dye usually at elevated temperature and in most commercially available reactive dye types in the presence of alkali, or continuous or discontinuous processes, such as the so-called pad-steam process, or the cold retention process can be used.
  • the textile material is first padded with a reactive dye liquor, the alkali required for fixation being usually applied in a separate impregnation step.
  • the dye fixation is then carried out by a steaming process, in the cold residence process by docking the impregnated goods and lingering for several hours at room temperature.
  • Other fixation options such as The treatment of the goods, which have been sealed with an alkali-free reactive dye liquor, using sodium hydroxide solution / water glass solution has become known and is practiced industrially.
  • reactive stains on cellulose should have very high wet fastness properties. In practice, however, it turns out that this is not the case. The reasons for this are of different types and may not yet be known in its entirety. However, it can be said that a more or less large proportion of the reactive dye used for dyeing does not react with the cellulose fiber, but with water molecules. When reacting with water, the reactive dye loses its chemical binding ability to the cellulose and is only bound to the fiber molecule by secondary valence forces.
  • DE-A-29 10 583 discloses a soaping aid for dyeings and prints on textile materials, which is based on the use of an alkali aluminum silicate, optionally in combination with polyvinylpyrrolidone.
  • Another possibility known from the prior art for improving the wet fastness of noun dyeings consists in aftertreatment with condensation products of cyanamide, formaldehyde and salts of organic amines or ammonium salts.
  • Japanese patent application 53-675 relates to the aftertreatment of vat dyeings for the purpose of improving the authenticity.
  • the technical problem here differs significantly from that of post-treatment of reactive dyeings.
  • cellulose material can be dyed and printed with reactive dyes without the use of alkali if it is pretreated with a wetting agent and an optionally quaternized reaction product of polyethyleneimine with a bifunctional alkylating agent, then dyed with reactive dyes by conventional methods, but without alkali and the dyeings are completed by rinsing, soaping and drying.
  • the auxiliary agent required for the pretreatment is known from US-A-4,588,413.
  • the aid is used there exclusively for the aftertreatment of dyeings with reactive dyes. Pretreatment with this aid and subsequent dyeing without alkali is not described there.
  • a method exclusively for the aftertreatment of reactive stains with compounds of a similar structure is also described in GB-A-2006279.
  • polyethyleneimine used is a molecule in which -NH2,> NH and -N ⁇ building blocks are present, which are linked together by ethylene groups are linked.
  • the polyethyleneimine contains about 50 to 600 ethyleneimine units.
  • primary, secondary and tertiary nitrogen functions are in a numerical ratio of approximately 1: 2: 1.
  • bifunctional alkylating agents can be used for the reaction with the ethyleneimine of the formula I.
  • Such known bifunctional alkylating agents correspond to formula II A - Z - A (II)
  • A is the residue of an alkylating agent and Z is either a direct bond or a divalent bridge member.
  • Preferred for the reaction with polyethyleneimine to be used according to the invention are those bifunctional alkylating agents in which A are groups of the formula -CH2-Y which are linked to one another via a bridge member of the formula IV, or those in which one of the radicals A is a group of Formula is -CH2-Y, which is bonded directly to an epoxy group.

  • this reaction involves the installation of crosslinking bridging links between the polyethyleneimine chains.
  • An external indication of this is that the viscosity of the aqueous solutions during the transition from uncrosslinked polyethyleneimine to the product crosslinked by the bifunctional alkylating agent increases significantly.
  • the polyethyleneimine can be reacted with the bifunctional alkylating agents without a solvent.
  • organic solvents in which the reactants are soluble such as, for example, lower alcohols, and in particular water, are suitable for this.
  • the reaction can be carried out in the temperature range between -10 and about 100 ° C.
  • the reaction is essentially completed in about 1 to 2 hours.
  • the reaction mixture In order to obtain aids to be used according to the invention which have particularly narrow-tolerance specifications, i.e. In order to achieve particularly good reproducibility of the production process, it is advantageous, after the main reaction has ended, for the reaction mixture to have a defined pH between 9 and 10 for several hours, usually 2 to 6 hours, at elevated temperature, advantageously between 60 and 100 ° C afterwards.
  • reaction products of polyethyleneimine used according to the invention with a bifunctional alkylating agent can optionally also be quaternized with C1-C4-, preferably C1-C3-alkyl groups.
  • the quaternization can be carried out using alkyl halides, preferably alkyl chlorides, or dialkyl sulfates by known methods.
  • This aid described above is applied to the textile material to be dyed or printed together with a wetting or padding aid from an aqueous liquor which is customary in the textile industry.
  • Alkane sulfonates, dialkyl sulfosuccinates, dialkyl phosphates or propylene oxide / ethylene oxide block polymers with a proportion of 40-80% by weight of ethylene oxide are used as such wetting or padding aids, but especially non-ionic compounds, for example oxyethylated Nonylphenol.
  • Raw or pretreated cotton or mixed fabrics containing cotton are suitable as textile materials.
  • the process according to the invention is particularly interesting for the pretreatment of cotton warp yarns with the aid described in the size. After weaving with untreated weft yarns and then alkali-free over-dyeing with reactive dyes, a denim effect is then achieved after washing out the fabric.
  • the pretreatment with the auxiliary together with a nonionic wetting agent is carried out from an aqueous liquor by customary methods by padding or in the exhaust process at temperatures of approximately 20 to 70 ° C., preferably 40 to 60 ° C., in the size from 80 ° C. to cooking temperature.
  • the liquor is adjusted to a weakly acidic pH, preferably pH 6.
  • the amount of auxiliary is about 3 to 10%, preferably 3 to 8%, based on the weight of the goods.
  • the amount of wetting agent is preferably 2 to 4 g / l.
  • the pretreatment liquor is then squeezed off and the goods are dried.
  • the goods pretreated in this way are then dyed with reactive dyes using customary methods and on customary dyeing units, for example using the cold dwell method or using an exhaust method.
  • the Fleet ratio can be about 1: 3 to 1:40. However, it is important here that, in contrast to the previously customary procedure, no alkali is used in the present case.
  • Suitable reactive dyes in this process are all known types of reactive dyes which contain groups which are reactive with the hydroxyl groups of cellulose and which, under the dyeing conditions described according to the invention, preferably react by reaction with the polymers described and fixed on the cellulose material.
  • the reactive groups are, for example, groups with easily removable substituents which leave an electrophilic residue, such as reactive groups of the vinylsulfone type, groups of the ring systems quinoxaline, phthalazine, triazine, pyrimidine or pyridazone substituted with halogen atoms or reactive groups substituted with alkylsulfonyl groups in the case of sulfonylpyrimidothiazole or sulfonylbenzylbenzene .

  • Suitable basic dye bodies of the reactive dyes are, for example, water-soluble azo, disazo, formazan, anthraquinone, dioxazine or phthalocyanine dyes.
  • Water-soluble azo and disazo reactive dyes which can also be metal complex reactive dyes, are preferably used. After dyeing, the goods are finished by rinsing, possibly soaping and drying.
  • the process according to the invention can be carried out not only with reactive dyes, but also in the same way with other types of dyes which contain anionic, for example sulfo groups, such as, for example, direct dyes, acid dyes and water-soluble sulfur dyes. Similar effects and fastness properties are achieved with these dyes as with the reactive dyes.
  • pigment dyes such as vat and sulfur vat dyes can also be used in the process.
  • the method according to the invention is not only suitable for dyeing textile material, but also for printing.
  • the textile material is printed with a printing paste which contains a marking dye and the auxiliary agent to be used according to the invention.

  • the subsequent post-treatment is carried out analogously to the dyeings.
  • the main advantage of the process according to the invention is that no alkali is required as a result of the pretreatment with the auxiliary described in the subsequent dyeing.
  • no alkali then goes into the wastewater, so that the salt pollution of the wastewater in the dyeing plants is significantly reduced.
  • the pretreatment described also partially results in a significant color deepening of the color compared to a coloration with the same amount of reactive dye in one conventional dyeing process.
  • water glass is used to a large extent as the alkali for fixing the reactive dyes. If this water glass is not carefully washed out after fixing, it can lead to annoying SiO2 deposits on the goods and thus impair the grip. This disadvantage is also eliminated in the method according to the invention.
  • This new process also makes washing out the unfixed dye residues easier by dispensing with alkali, since in the presence of alkali the cotton fiber swells and the unfixed dye is more strongly absorbed. This does not apply to the method according to the invention.

  • the cotton chains are dried with contact heat at approx. 130 ° C.
  • modified starch or mixtures of modified starch and PVA can also be used.
  • carboxymethyl cellulose or carboxymethyl starch as a sizing agent is not possible, since this can lead to precipitation with the cationic alkali ethylene in the condensate.
  • the cotton chains are woven with the weft of cotton and the fabric obtained is padded with a solution on a cold dwelling system consisting of dyeing pad and docking device, which solution, for example 10 g / l CI Reactive Blue 19 (CI No. 61200) and 4 g / l wetting agent (ethoxylated nonylphenol) contains.
