Definitions

  • the present invention relates to a process for fixing pigment prints and pigment dyeings on fibre material with ionising radiation or by irradiation with UV radiation in the presence of photoinitiators.
  • Printing or dyeing fibre materials with pigment dyes by the so-called pigment printing or pigment dyeing process is one of the oldest known processes for the production of coloured textile goods. Nevertheless, the current printing and dyeing processes do not yet meet all the requirements made on them today, especially not regarding environmental impact and energy consumption.
  • this invention relates to a process for printing or dyeing fibre material with pigment dyes, which comprises applying to the fibre material a dye formulation comprising at least one pigment dye and at least one pigment dye binder as well as optional further auxiliaries and then fixing it with ionising radiation, or applying to the fibre material a dye formulation comprising at least one pigment dye, at least one pigment dye binder and at least one photoinitiator as well as optional further auxiliaries and then fixing it with UV radiation.
  • One advantage of the novel processs is that it dispenses with the energy-consuming heat setting required in the conventional pigment printing and pigment dyeing processes.
  • the fixing process consists in briefly irradiating the fibre material to be printed or dyed, e.g. textile fibre material, with ionising radiation or with UV radiation in the presence of at least one photoinitiator after printing or dyeing in the moist or dry state.
  • the printed or dyed fibre material is advantageously irradiated and fixed at elevated temperatures, for example from 40 to 120° C, preferably from 60 to 100° C.
  • the irradiation can be carried out either immediately after the drying process or the cold printed fibre material may be heated to the desired temperature before irradiation, using e.g. an infrared heater.
  • lonising radiation is to be understood as being radiation which can be detected in an ionisa- tion chamber.
  • Suitable heavy charged particles are protons, atom nuclei or ionised atoms.
  • Light charged particles, e.g. electrons, are particularly important for the process of this invention.
  • Suitable X-rays are bremsstrahlung and also characteristic radiation. ⁇ -Radiation is to be mentioned as important particle radiation of heavy charged particles.
  • the ionising radiation can be produced by one of the customary methods.
  • suitable radiation sources are natural or synthetic radioactive substances and, especially, atom reactors.
  • the radioactive fission products obtained from nuclear fission are another important radiation source.

  • Suitable radiation sources in this connection are thermo, electron impact, low-voltage arc, cold cathode and high frequency ion sources.
  • Electron beams are particularly important for the process of this invention. These are pro ⁇ prised by accelerating and concentrating electrons which are emitted via thermionic, field or photo emission and also via electron or ion bombardment from a cathode.
  • Radiation sources are electron guns and accelerators of conventional make. Examples of radiation sources are known from the literature, inter alia from the International Journal of Electron Beam & Gamma Radiation Processing, in particular 1/89 pages 1 -15; Optik, 77 (1987), pages 99-104.
  • ⁇ -emitters e.g. strontium-90.
  • the ⁇ -emitters which can easily be produced using, in particular, cesium-137- or cobalt-60- isotopic sources, are also to be mentioned as ionising radiation which can be of advantageous technical use.

Particularly advantageous photoinitiators are also copolymerisable photoinitiators such as those mentioned, inter alia, in “Polymers Paint Colour Journal, ⁇ 80, p42 et seq. (1990)". It is also suitable to use cationic photoinitiators such as triarylsulfonium salts, diaryliodonium salts, diaryliron complexes or in general structures such as those described in "Chemistry & Technology of UV & EB Formulation for Coatings, Inks & Paints", Vol. 3, edited by SITA Technology Ltd., Gardiner House, Broomhill Road, London, 1991.

  • high- and medium-pressure mercury lamps which may be doped e.g. with iron halide or gallium halide. These lamps may also be excited via microwaves or may be pulsed to concentrate the radiation in peaks. It is also possible to work with pulsed xenone lamps if a higher component of longwave UV radiation is required.
  • the customary UV radiation sources are generally suitable, such as those described in "Chemistry & Technology of UV & EB Formulation for Coatings, Inks & Paints", Vol. 1 , edited by SITA Technology, Gardiner House, Broomhill Road, London, 1991.

  • Conventional irradiation times with UV radiation are from 1 second to 20 minutes, preferably from 5 seconds to 2 minutes.
  • the fixing can be terminated by interrupting the irradiation so that it can also be carried out discontinuously.
  • the irradiation can be carried out in an inert gas atmosphere, e.g. under nitrogen, to prevent inhibition by oxygen.

  • the novel process gives prints having good allround fastness properties, e.g. good fastness to water and light.
  • the special embodiment of this invention depends especially on the kind of ionising radiation to be used and its manner of production. If, for example, the printed fibre material is to be irradiated with ⁇ -rays, then the material is exposed to the radiation enclosed in a cell. If higher radiation dosages are desired at lower radiation intensity, then the material to be irradiated can be exposed to the radiation in several passages.
  • a preferred embodiment of this invention is that, wherein the printing as well as the fixing of the fibre material with the pigment dyes are carried out continuously.
  • the prints obtainable by the novel process on cellulosic fibre material have good allround fastness properties; they have, for example, good fastness to light, wetting, such as to washing, water, seawater, cross-dyeing and perspiration, good fastness to chlorine, rubbing, ironing and pleating and are distinguished in particular by high tinctorial strength and a brilliant shade.
  • the radiation dosages are given in conventional manner in Mrad (megarad), 1 rad corresponding to an absorption of 10 "2 J/kg (joule/kg).
  • the UV irradiation is carried out using a 120 watt/cm medium-pressure mercury lamp at transport speeds of 10 m/min.
  • the fabric referred to in the following Examples is printed on one side and is irradiated under an inert gas atmosphere.
  • Parts and percentages are by weight and temperatures are given in degrees Celsius. The relationship between parts by weight and parts by volume is the same as that between the gramme and the cubic centimetre.
  • a cotton fabric is printed with a printing paste containing per 1 kg of printing paste
  • a red pigment print is obtained having good fastness to wetting and light.
  • Example 1 The procedure of Example 1 is repeated, but the dried print, which is temporarily stored cold, is heated in an infrared predrier to 100° C before irradiation. The subsequent irradiation also gives a red pigment print having good fastness to wetting and light.
  • a cotton fabric is printed with a printing paste containing per 1 kg of printing paste
  • a red pigment print is obtained having good fastness to wetting and light.
  • a cotton fabric is printed with a printing paste containing per 1 kg of printing paste
  • a blue pigment print is obtained having good fastness to wetting and light.
  • Example 4 The general procedure of Example 4 is repeated, but the dried print, which is temporarily stored cold, is heated in an infrared predrier to 100° C before irradiation. The subsequent irradiation also gives a blue pigment print having good fastness to wetting and light.
  • a cotton fabric is printed with a printing paste containing per 1 kg of printing paste
  • a blue pigment print is obtained having good fastness to wetting and light.
