Definitions

  • the invention relates to a colored sponge cloth based on regenerated cellulose, which is reinforced with fibers. It also relates to a process for producing a colored sponge cloth, in which viscose is mixed with fibers, at least one pore former and at least one colorant, the mixture is applied in layers on a conveyor belt and the viscose is then regenerated to cellulose.
  • Sponge cloths have been known for a long time. They are generally layer-like structures with a thickness of approximately 0.4 to 2.0 cm (in the dry state). They are generally manufactured using the viscose process (cellulose xanthate process). In order to make them mechanically more stable, they usually contain textile fibers or a plastic net. In a common process for producing sponge cloth, for example, about 3 parts by weight
  • about 83 parts by weight of Glauber's salt ( sodium sulfate decahydrate) are added in portions and the resulting mass is kneaded for a further 20 to 30 minutes.
  • the mass is then applied as a thin layer on a perforated steel belt and, on this belt, passed through a bath containing potassium hydroxide at about 95 ° C.
  • the lye is then removed again by treating with dilute sulfuric acid and various washing baths.
  • the sponge cloth thus obtained is then dried and can be wound up.
  • the cotton fibers remain more or less undyed. If the fibers are also distributed inhomogeneously, the appearance of the sponge cloth is impaired, which many consumers perceive as a lack of quality.
  • the object was therefore to provide a sponge cloth which is evenly colored, ie in which the regenerated cellulose and the fibers have the same color.
  • the sponge cloth should also be easy and inexpensive to manufacture.
  • the present invention accordingly relates to a colored sponge cloth based on regenerated cellulose, which is reinforced with fibers, and is characterized in that the fibers and the regenerated cellulose are colored with at least one reactive dye.
  • reactive dyes are those dyes which can form covalent bonds with the cellulose and the fiber material.
  • the dye molecules each have at least one anchor group that is linked to the
  • Suitable reactive anchor groups are in particular 2,4-difluoro- [1,3,5] triazin-2-yl-, 2,4-dichloro- [1,3,5] triazin-2-yl-, 2,5,6 - Trichloropyrimidin-4-yl and vinylsulfonyl groups.
  • the dye molecules optionally also have a plurality of reactive anchor groups which can be the same or different from one another. Instead of vinylsulfonyl groups, too
  • Groups occur from which vinyl sulfonyl groups form under the reaction conditions. These are, for example, groups of the formula -SO 2 - CH 2 -CH 2 -O-SO 3 " from which sulfate is eliminated under the action of aqueous alkali. Suitable reactive dyes are available, for example, under the names ⁇ Procion H-EXL, Procion XL + or ⁇ Levafix EN by
  • These dyes contain, for example, diphenylazo, anthraquinone or triphendioxazin groups as chromophore. So-called are particularly suitable among these dyes
  • Hot dyes which react with cellulose at temperatures of approximately 75 to 103 ° C., preferably 80 to 98 ° C., particularly preferably 90 to 95 ° C.
  • cold and warm dyes can also be used in principle.
  • Cold dyeing is generally carried out in a temperature range from 20 to 70 ° C., preferably in the range from 40 to 65 ° C and especially in the range of 50 to 60 ° C.
  • Cold dyeing dyes are generally more reactive than hot dyes.
  • the proportion of reactive dyes is generally about 0.001 to 5.00% by weight, preferably 0.05 to 3.00% by weight, particularly preferably 0.50 to 1.50% by weight, in each case based on the Total weight of cellulose and fibers.
  • the proportion naturally also depends on the type of dye.
  • the fibers are preferably cotton, viscose or polyamide fibers.
  • Mixed fibers e.g. B. those made of cotton and PA or
  • Cotton fibers which have been dyed with the reactive dyes in a separate step can be used in the production of the sponge cloth according to the invention. This can be done, for example, by a so-called
  • Flakes are stained.
  • the at least one dye is first dissolved in water, if appropriate with heating, and the dye solution is then added to an aqueous salt solution (which contains, for example, 60 g / l NaCl and 20 g / l Na 2 CO 3 ) and the two are mixed together.
  • the cotton fibers are added to the dyeing solution. To avoid color deviations, after the
  • Fix for example with acetic acid
  • the same reactive dye or the same mixture of different reactive dyes can be used for coloring the regenerated cellulose.
  • the sponge cloth according to the invention is preferably produced by a process which comprises the following steps: a) providing viscose solution, fibers wetted with alkali, pore-forming agents and an aqueous solution of at least one reactive dye, b) mixing the fibers with the viscose, c) Admixing the aqueous solution of the at least one reactive dye to the mixture of fibers and viscose, d) admixing the pore former to the mixture according to c), e) forming the mixture into a layer on a conveyor belt (the application is expediently carried out with a metering pump and a Application nozzle; the height of the layer can be regulated with an iron), f) Removing the pore former and regenerating the viscose to cellulose in an aqueous alkaline bath (which contains, for example, KOH or NaOH as an alkaline agent) at a temperature of 90 to 100 ° C, preferably about 95 ° C (after regeneration of the cellulose
  • the pore former is preferably Glauber's salt. It has a melting point of 32.4 ° C. In addition, other low-melting and water-soluble inorganic salts are also suitable in principle. The melting point should generally be below the temperature of the regeneration bath.
  • the pore former also acts as a fixing aid, which ensures that the reactive dye or the dye mixture is particularly firmly bonded to the cellulose.
  • the proportion of the pore former is advantageously 50 to 90% by weight, preferably 70 to 85% by weight, in each case based on the total weight of viscose, fibers and pore former.
  • an acid bath in particular a bath of dilute sulfuric acid
  • the acid is neutralized in the following stage, the sponge cloth is then washed and dried as described.
  • the sponge cloth according to the invention is characterized by a uniform color with good wash fastness, wet fastness and high color strength. It can be printed as usual. A printing paste which contains at least one reactive dye can also be used for printing. The pressure is then fixed at temperatures of around 80 to 230 ° C with steam or with dry heat. In this way, strong-colored prints with very good fastness properties are obtained, in particular with very good light and wash fastness.
  • the following examples serve to illustrate the invention.
  • the reactive dye was first dissolved in warm water. The solution was then added to a viscose / cotton fiber mixture and kneaded for about 20 minutes. The Glauber's salt was then added and the mixture kneaded for a further 30 minutes. The sponge cloth mass obtained was then applied in the form of a thin layer to a perforated steel strip. The cellulose was then regenerated from the viscose in an aqueous KOH bath at a temperature of about 95 ° C. During the 15 min. in the KOH bath, the pore former was simultaneously removed from the sponge cloth. The sponge cloth was then transferred to a bath with dilute sulfuric acid (about 10% by weight). The last remnants of the alkali were then washed out with plenty of water. This way you get a permanently blue colored sponge cloth.
  • Example 2 Example 1 was repeated with the only difference that instead of 0.5 g
  • Example 3 Example 1 was repeated with the only difference that instead of 0.5 g
  • ⁇ Levafix CA a mixture of 0.25 g ⁇ Cibacron HRN01 (a blue reactive dye) and 0.25 g ⁇ Cibacron HG (a yellow reactive dye) was used. With the dye mixture an intensely and permanently green colored sponge cloth was obtained.
