Definitions

  • This invention relates to electrostatic flocking processes using man-made flock fibres.
  • the single flock fibres In order to obtain a dense and uniform pile, the single flock fibres must be able to glide smoothly over each other and must flow easily through a metal sieve in the flocking apparatus. They must furthermore spring quickly between the two electrodes of the electric field, until they are finally trapped by the adhesive-coated base.
  • the flow and gliding properties of flock can be improved by the application of softening agents, but a good spring capacityv in the electric field depends above all on the electrical conductivity of the fibres.
  • French patent specification No. 1,257,894 proposes the uses of suspensions of montmorillonite, a mineral well known for its swelling prop erties in water, and French patent specification No. 1,157,657 describes, for the same purpose, mixtures of surface active agents with paraifin oil and silica.
  • the antistatic eifect of mixtures containing highly dispersed silica and oily lubricants is mentioned in an article in Melliands Textilberichte, 33 (1952) 957.
  • German patent application 1,098,913 proposes the treatment of flock with well known anti-electrostatic agents, such as polyglycol esters or phosphoric acid esters with the addition of potassium and sodium salts.
  • the present invention provides a process for electrostatic flocking with man-made fibres in which by a novel method good flow and gliding properties and a good spring capacity in an electrostatic field are imparted to the flock fibres as a new anti-electrostatic combination, while the mechanical properties of the fibres are not impaired.
  • tannin includes gallic acid and digallic acid as well as the various types of tannin.
  • tannin and potassium antimonyl tartrate as auxiliaries in certain dyeing processes is known, e.g. in dyeing natural and regenerated cellulose fibres with basic dyes and for improving the wet fastness of acid wool dyes. It is also known to treat synthetic fibres and textiles, especially stockings, with solutions containing alum, tannin, and aluminium acetate to improve their durability. Synthetic fibres have also been treated with tannin solutions to make them smooth and waterproof.
  • tannin and potassium antimonyl tartrate as anti-electrostatic agents for man-made fibres has, however, not been described.
  • the treatment of man-made fibres with tannin and potassium antimonyl tartrate is very effective in producing fibres of good electrical conductivity which possess an excellent spring capacity in an electrostatic field.
  • the treatment is equally applicable to dyed and undyed fibres, and an additional advantage is the durability of the antistatic etfect.
  • the fibres treated in accordance with the invention keep their good spring capacity even after prolonged storage; moreover, they are insensitive to changes of temperature and humidity of the air produced by changes of weather and seasons.
  • Another advantage of the process is that the agents used need only be employed in very low concentrations.
  • a further improvement of the properties of the fibres for electrostatic flocking processes, especially of their flowand gliding properties, can be obtained, if, after their treatment with tannin and potassium antimonyl tartrate, the fibres are treated with an aqueous solution containing an anionic finishing agent, and, option-ally, also a watersoluble alkali metal or ammonium salt.
  • an anionic finishing agent such as sodium sulphate or ammonium sulphate may be used, and sodium silicate in the form of water-glass is also effective, especially if the solution is made faintly acid.
  • a further modification is possible by treating the fibres before the treatment with the tannin solution with an aqueous solution of an alum, preferably potassium aluminum sulphate.
  • the flock fibres are dispersed in an aqueous solution at, e.g. about 70 C. and brought to a pH of 4-5, e.g. by the addition of acetic acid, and containing preferably between 0.04 and 0.2 percent by weight of tannin. Ordinarily the dispersion is stirred for minutes, 0.01 to 0.05 percent by weight of potassium antimonyl tartrate is then added, and stirring is continued for another 10 minutes. To remove the adhering solution, the fibres are centrifuged for 10 minutes and finally dried. If it is desired to apply a finishing treatment, the drying is omitted, and the fibres are, following centrifuging, transferred to an aqueous solution at, e.g., about 50 C. containing preferably, between 0.2 and 1.0 percent by weight of the finishing agent and stirred for about 25 minutes. The fibres are then centrifuged again and dried.
  • an aqueous solution at, e.g., about 50 C. containing preferably, between 0.2 and 1.0 percent by weight
  • alkali metal or ammonium salts are to be used, between 0.3 and 1.5 percent by weight of such substances is added to the finishing bath.
  • sodium silicate is employed as the alkali metal salt, it is recommended to prepare a solution of the required strength, and, prior to addition of the finishing agent, to add acetic acid, so that the pH of the solution is less than 7.5 and preferably between 4 and 5. It is further recommended to use, in combination with sodium silicate, the sodium salt of cetyl alcohol sulphonic acid as finishing agent. Otherwise, the preferred procedure is the same as if a finishing treatment Without the addition of an alkali salt is applied.
  • the fibres are dispersed in an aqueous solution at, e.g. 70 C., brought to a pH of 4-4 by addition of acetic acid and containing between 0.02 and 0.1 percent by weight of an alum, usually potassium aluminum sulphate.
  • the dispersion is then stirred for 10 minutes, and tannin and, subsequently, potassium antimonyl tartrate are added, the treatment being carried out, as described above, either with or without the use of anionic finishing agents and alkali metal or ammonium salts.
  • the weight ratio between fibres and solutions should vary between 1 to and 1 to 25; usually 1 part of fibres requires parts of solution. It is recommended, prior to treatment, to remove any oily or fatty sizes adhering to the fibres. This is simply done by washing the fibres in a warm bath containing soap or a synthetic detergent.
  • man-made fibres treated according to the method described are then secured to an adhesive-coated base under the influence of a high-tension electrostatic field in conformity with well-known processes.
  • Example I 50 g. of polyhexamethylene adipamide fibres of 2.5 mm. length and a titre of 2.2 tex are dispersed in 1000 g. of an aqueous solution at 70 C. containing 0.25 g. of acetic acid and 0.5 g. tannin. The dispersion is stirred for 10 minutes, 0.25 g. of potassium antimonyl tartrate are added, and stirring is continued for another 10 minutes. To remove the adhering solution, the fibres are centrifuged for 10 minutes and dried at 25 C. The fibres possess a good spring capacity in an electrostatic field and are very suitable for use in electrostatic flocking processes.
  • Example II 50 g. of dyed polycaprolactam fibres of 2.5 mm. length and a titre of 2.2 tex are dispersed in 1000 g. of an aqueous solution at 70 C. containing 0.25 g. of 80% acetic acid and 0.5 g. tannin. The dispersion is stirred for 10 minutes, 0.25 g. potassium antimonyl tartrate is added, and stirring continued for another 10 minutes. The fibres are then centrifuged for 10 minutes and dispersed in 1000 g. of an aqueous solution at 50 C. containing 3 g. of a mixture of cetyl alcohol and an ammonium sulphonate of cetyl alcohol, and stirred for 25 minutes.
  • the fibres are centrifuged for 10 minutes and dried at 25 C.
  • the fibres possess a good flow and good spring capacity in an electrostatic field. They kept these properties after a storage for 6 months and after temporary heating to 70 C., and are very suitable for electrostatic flocking processes. Fibres treated only with the anionic finishing agent solution, did not possess any of these properties.
  • Example III 50 g. of dyed polyhexamethylene adipamide fibres of 1 mm. length and a titre of 0.3 tex are dispersed in 1000 g. of an aqueous solution at 70 C. containing 0.5 g. of 80% acetic acid and 0.5 g. of potassium aluminum sulphate. The dispersion is stirred for 10 minutes, 1 g. tannin is added, and stirring is continued for 10 minutes, whereupon 0.25 g. of potassium antimonyl tartrate are added and the dispersion is stirred for another 10 minutes. The fibres are centrifuged for 10 minutes and dispersed in an aqueous solution at 50 C. prepared as follows: 8 g. of water-glass of specific gravity 1.4 are mixed with 1000 g.
  • polyhexamethylene adipamide fibres, cellulose triacetate fibres, polyethylene terephthalate fibres and polyacrylonitrile fibres which are only treated with an acidified aqueous solution containing water-glass and the foresaid anionic finishing agent, possess an unsatisfactory spring capacity in an electrostatic field and are unsuitable for electrostatic flocking processes.
