Definitions
- the invention relates to a method for producing spinneret plates according to the preamble of claim 1.
- spinneret plates are required for the production of fibers, the raw material of organic or inorganic material in a flowable state being pressed through a large number of spinneret channels in the plates.
- the spinneret channels consist of nozzle capillaries through which the material emerges as a fiber, and significantly more preliminary channels to which the material to be spun is fed.
- the pre-channels are often in the form of funnels which taper towards the nozzle capillaries in order to eventually merge into the latter.
- the invention has for its object to show a method of the generic type by which a continuous transition from the pre-channels to the nozzle capillaries is ensured.
- nozzle capillaries can also be produced in the form of tubular approaches using the same solution principle.
- Spinneret plates with tubular nozzle capillaries are used particularly advantageously as components for the production of spinneret devices for the production of hollow or multicomponent fibers.
- Such spinneret devices generally consist of a plurality of spinneret plates arranged one above the other.
- nozzle capillaries can be manufactured with extreme precision and uniformity both in their individual cross-section and in their mutual position according to the method according to the invention and the mutual adjustment of several relatively large spinneret plates for assembling the spinneret devices is not a major problem, the production of hollow or Multi-component fibers with any cross-section and structure possible. This makes it possible to produce fibers with new and unusual uses.
- Claim 3 shows how to proceed if the metallic plate with the funnel-shaped pre-channels is to be produced by deep lithographic-galvanic means.
- the continuous transition from the pre-channels to the nozzle capillaries that can be achieved with the invention is not only with circular cross sections, but also with profiled, e.g. Star-shaped cross sections of the nozzle capillaries possible.
- the pre-channels 144 are then filled with a removable filling material 152 which connects to the regions 145 (FIG. 2).
- columnar negative shapes 151 of the nozzle capillaries are formed on the plate 141.
- an electroplating layer 162 including the negative molds 151 is produced on the metallic plate 141 serving as the electroplating electrode (FIG. 3).
- the filling material 152 and the negative molds 151 of the nozzle capillaries are removed after the electroplating layer 162 has been leveled, so that a spinneret plate 163 consisting of the parts 141 and 162 is formed, in which the nozzle capillaries 161 connect seamlessly to the funnel-shaped pre-channels 144 (FIG. 4).
- the irradiated areas 142b are first coated with a liquid developer removed ( Figure 2a) and then the removed areas and the pre-channels 144 filled with a removable filler 152a, which is less soluble than the positive resist material of the layer 142a ( Figure 2b). Then the non-irradiated areas of the layer 142a are removed, so that columnar negative shapes 151a of the nozzle capillaries are also formed in this case on the metallic plate 141 according to FIG. 2c.
- the further steps incrementating and leveling the electroplating layer 162, FIG. 3a, removing the filling material 152a) correspond to those described above, so that a spinneret plate 163 is also produced in this case, as is shown schematically in FIG.
- the method according to the invention can also be used for the production of spinneret plates with tubular nozzle capillaries.
- the metallic plate 141 with the pre-channels 144 is used as an irradiation mask (FIG. 5), whereupon the layer 142 is again partially irradiated from the opposite side.
- a mask is used for the irradiation with the high-energy radiation 181 (FIG. 6), the absorber structures 182 of which correspond to the outer diameters of the tubular attachments of the nozzle capillaries, so that the irradiated areas 174 and 175 are non-irradiated tubular areas 183 Wrap layer 142.
- the irradiated areas corresponding to the interior of the nozzle capillaries are first removed with a liquid developer and replaced by a radiation-insensitive filling material 191a, which also fills the pre-channels 144 (FIG. 6a). Then there is repeated partial irradiation of the layer 142a with high-energy radiation 181 via a mask, the absorber structures 182a of which have openings 182b which correspond to the outer diameters of the tubular attachments for the nozzle capillaries.
- tubular, irradiated areas 183a are formed between the filling material 191a and the non-irradiated resist material of the layer 142a, which are removed with a liquid developer, so that tubular cavities 192a are formed (FIG. 7a).
- the further treatment is carried out analogously to the description of FIGS. 8 and 9.
- a layer 121 made of a negative resist material is applied to a plate 12 serving as a galvanic electrode.
- This layer 121 is partially irradiated with parallel X-ray radiation 123 from an electron synchrotron via a mask 122 arranged at a short distance.
- the unit consisting of mask 122, resist layer 121 and plate 12 executes a wobble movement (arrows) relative to the beam direction.
- the openings 125 in the absorber structure of the mask 122 have a cross section that corresponds to that of the nozzle capillaries.
- the radiation 123 creates areas 124 in the resist layer 121 with a funnel-shaped cross section widening to form the plate 12, which are more difficult to dissolve due to the radiation compared to the non-irradiated areas of the layer 121.
- negative forms 131 of the funnel-shaped pre-channels are formed on the plate 12.
- the plate 12 and the negative molds 131 are removed, so that a metallic plate 141 according to FIG. 12 is provided with funnel-shaped pre-channels 144.
- the metallic plate with funnel-shaped pre-channels can also be produced by deep lithographic-galvanic means when using a positive resist material.
- the areas which have been created during the irradiation with a wobble movement according to FIG. 10 are removed and replaced by a filler material.
- After removing the remaining resist material with egg A developer thus obtains negative forms of the funnel-shaped pre-channels from the filling material, which are processed further in accordance with FIGS. 11 and 12.
- a wobble movement can take the place of a wobble movement.
- PMMA is used as the positive resist material, which after the irradiation is dissolved in a liquid developer of butyl diglycol, morpholine, ethanolamine and water.
- the negative resist material is based on polystyrene, the developer required for this consists of a mixture of ketones and higher alcohols.
- the galvanic deposition of metal takes place in a chloride-free nickel sulfamate bath at a temperature of 52 ° C.
- the removable radiation-insensitive filling material consists of a mixture of an epoxy resin and an internal release agent.
