Definitions

  • Sen fibres can be d slat textlle materials made of cellulose ponent ca ablye with reactive dyestuffs having as comcyclobut 1)p e of reacting the ,B-(2,2,3,3-tetrafluor group f0yrm-izrilcryloylammoor vinylsulfone group or a group by anog n the presence of alkalies a vinylsulfone alkali-136 conafiii 535F332 iiifol l dyestuffs under lose fibres.
  • p ice metering pumps or mixing devices are brought into action in such padding processes m which, generally, relatively large amounts of strong alkalies (for example sodium hydroxide or sodium metasihcate) are used and in which-especially when large batches are dyed-the dyebath is abandoned partially for, a prolonged period of time in the preparing vessel.
  • Sa1d arrangements allowthe dissolved dyestuffs to be brought into contact with the alkali only shortly before they are introduced into the padding machine (cf. Textil-Praxls, 1963, page v1189).
  • a disadvantage of this process how, ever, is that only few dye-houses possess such metering pumps or mixing devices, which is due to the hlgh purchase price for such devices.
  • a further disadvantage of the pad-batchor the padshortdwell-process lies in the fact that after dwelling, when drying the textile material without preceding acidification of the goods, the colour yield isreduced, owing to cleavage of the dyestuff-fibre-linkage. Therefore it is inappropriate to use the non after-treated textile material in the printing.
  • textile materials made of native or regenerated cellulose fibres can be dyed according to the padding process with reactive dyestuffs having as a group capable of reacting at least one ⁇ 3-(2,2,3,3- tetrafluoro-cyclobutyl)-acryloylarnino group or a vinylsulfone group or at least one group forming in an alkaline medi um a vinyl sulfonegroup, by using in said process padding Therefore liquors containing besides the above-mentioned dyestuffs as agents having alkaline action a liquid alkali metal silicate.
  • the padded material is allowed to dwell at temperatures of up to 100 C., preferably at room temperature, the fabric being wound up on a roller or piled up. The dwelling period is generally between 1 hour and 30 hours.
  • alkali metal silicate water glassy when carrying out the process of the present invention
  • a- As reactive dyestuffs representatives of the various organic dyestuff classes can be used according to the present invention, for example azoand anthraquinone dyestuffs, containing either at least one B-(2,2,3,3-tetrafluoro-cyclobutyl)-acryloylaminoor a vinylsulfone group or at least one group which can be converted into a vinylsulfone group when exposed to alkaline agents during the dyeing process.
  • the appropriate azo dyestuffs may, if desired, be used in metallized form.
  • liquid alkali metal silicates water-glasses
  • commercial sodium silicates sodium silicates
  • sodium silicates having a concentration of about 37 to about 60 B., corresponding to an SiO -content of the aqueous solution of about 27.2 to about 38.2 percent by weight.
  • the amount of the fixing agent used depends on the concentration of the alkali metal silicate applied, on the dyestuif concentration and on the nature of the dyestutf, and ranges generally from about g. to about 350 g., preferably from about 50 g. to 200 g. per liter of padding bath. Furthermore, it is possible to add to the dye baths still a sodium hydroxide solution besides the silicate, but the amount of sodium hydroxide solution (referred to sodium hydroxide solution of 38 B.) is not to exceed 10% of the amount of alkali metal silicate used, since otherwise the stability of the bath is reduced.
  • EXAMPLE 1 A cotton poplin is padded in a padding machine-without using a metering pump or mixing deviceat a squeezing effect of 70 percent by weight with a padding liquor of C. containing per liter of water 10* g. of the dyestuif of the formula ease 4
