Definitions

  • the present invention relates to a new process for single-bath, single-stage dyeing of textile materials consisting of wool and cellulose fibers with highly reactive reactive dyes after an exhaust process, in which the textile material in the presence of one or more reactive dyes and one or more neutral salts slowly from alkaline to acidic falling pH and at the same time slowly rising temperature is treated.
  • an alkaline starting dye bath is listed as a preferred embodiment, which is made acidic by the gradual addition of doped amounts of acid, with the dye then being virtually completely fixed in the acidic medium.
  • the aim of the present invention is namely to optimally dye tone-in-tone a textile material consisting of wool and cellulose fibers in an economically justifiable time.
  • Dyes are used to dye wool and cellulose fibers at the same time. These are reactive dyes having a constitutionallysekonstante of 0,8-10- 2 min -.1 (all disclosed in the application text reactive dyes satisfy this condition). The fiber mixture sometimes begins to color even at the alkaline starting pH.
  • the wool / cellulose blended fabric is optimally colored.
  • FR-A-1 512 665 the dyeing of cellulose fibers or of cellulose / polyester mixed fibers at temperatures above 100 ° C. is known. These temperatures can only be reached in closed dyeing machines.
  • FR-A-1 512 665 is primarily the dyeing of cellulose / polyester mixed fibers, the dye bath containing reactive and disperse dyes. In the method according to the invention, temperatures of max. 100 ° C reached. In practice one works at final temperatures of approx. 95 ° C.
  • the usable reactive dyes in the present process have a hydrolysis constant of at least 0,8.10- 2 2 min-1 at pH 11 and 40 ° C. (For the determination of the hydrolysis constant, see D. Hildebrand in: The Chemistry of Synth. Dyes, Vol. VI, 1972, 346 ff, Academic Press, Inc. New York and London).
  • Suitable reactive dyes are, above all, sulfo-containing, water-soluble, organic dyes from the series of anthraquinone, azo, azo metal complex, formazane, oxazine and phthalocyanine dyes.
  • the reactive dyes preferably contain at least one 2,3-dichloroquinoxalinyl, dichlorotriazinyl, monofluorotriazinyl, monofluoropyrimidinyl or difluoropyrimidinyl radical as the reactive group.
  • Suitable alkalis for the process according to the invention for adjusting the starting pH are those which, alone or in a mixture, give a pH of 10 to 11.
  • Examples include sodium hydroxide solution, trisodium phosphate, soda, disodium phosphate, sodium bicarbonate and calcium hydroxide.
  • so much alkali is added that the dye liquor assumes a pH of 9 to 11. This is the starting pH of the process according to the invention.
  • An alkaline buffer mixture (in particular phosphate buffer) is preferably used to adjust the starting pH.
  • the dye liquor contains 20 to 150 g / l, preferably 50 to 100 g / l of a neutral salt such as sodium sulfate or sodium chloride, and 0.5 to 2 g / l, preferably 1 to 1.5 g / l of a leveling agent. If necessary, further dyeing aids such as wetting agents (e.g. alkyl phosphates), defoamers (e.g. mineral or silicone emulsions) or eluents (e.g. ethoxylated fatty acid amides) may be included.
  • wetting agents e.g. alkyl phosphates
  • defoamers e.g. mineral or silicone emulsions
  • eluents e.g. ethoxylated fatty acid amides
  • Suitable leveling agents are those described in DE-B-1 619 530.
  • Leveling agents such as those mentioned in DE-B-1 258 817 are also suitable.
  • the leveling agents which can preferably be used in the process according to the invention belong to the class of ethoxylated amines or amine oxides.
  • the pH of the dye liquor is changed by adding an agent which eliminates acid in the alkaline dye liquor or by slowly metering in acid.
  • the acid can be added in the form of the free acid (e.g. acetic acid) or an acidic salt.
  • Possible acid releasing agents are: Water-soluble derivatives of organic or inorganic acids, which release acids when heated in an alkaline medium and thus the pH value of the dye bath, which has an alkaline reaction at the beginning of the fixing process, in the weakly acidic range up to a pH value of 6 -5 convict. This pH of 6-5 is the final pH of the process according to the invention.
  • acidic salts preferably monosodium phosphate or sodium bisulfate
  • the dyeing bath is preferably set at 40-60 ° C and brought to about 30-60 minutes Temperature stability within 40-50 minutes to boiling temperature, and 1/2 to 1 hour at this temperature out (ca. 100 ° C).
  • the liquor is then drained off, the dyed fabric is rinsed with water and soaped with an aqueous ammonia solution.
  • 100 parts of a wool / cotton blended yarn consisting of 60 parts of wool and 40 parts of cotton are treated in the form of a cheese on a yarn dyeing machine with a 45 ° C warm liquor, which consists of consists.
  • the mixture is heated to the cooking temperature at 1 ° / minute and treated at this temperature for a further 60 minutes.
  • the liquor is then drained off and aftertreated with 2 parts of a 25% commercial ammonia solution in 1000 liquors at 80 ° for 20 minutes.
  • 100 parts of a wool / cotton blended yarn, consisting of 80 parts of cotton and 20 parts of wool, are treated in the form of a package on a yarn dyeing machine with a 45 ° C warm liquor, which consists of consists.
  • the mixture After draining off the rinsing liquor, the mixture is soaped at the boil for 20 minutes using a liquor containing 2 parts of 25% ammonia per 1000 parts.
  • 100 parts of a wool / cotton blended yarn consisting of 50 parts of wool and 50 parts of cotton are treated on a tree dyeing machine at 40 ° with a liquor which consists of consists.
