Definitions
- the present invention relates to a method for surface covering technical-fabric fibers, in particular for screen printing processes.
- the surface to be printed upon is entrained with a comparatively high speed between the printing cylinder and a further cylinder operating as a bearing surface.
- the ink is supplied by an ink supplying system arranged inside the first cylinder, thereby providing a continuous type of printing system.
- the fabric material to be used for making the printing surface must have a high flexure stiffness, a large size and a high mechanical stability, and a good resistance against corrosion, as well as a thin thickness.
- the aim of the present invention is to overcome the above mentioned problems, by providing a method for surface covering technical-fabric fibers, in particular for screen printing processes, allowing to stiffen, by increasing the flexure modulus, already made technical fabric materials comprising polymeric fibers, by depositing inorganic oxides, even of an organically modified type, and by directly continuously applying the process on the already existing material.
- a main object of the present invention is to provide such a method allowing the mesh size to be held unaltered, in particular without altering the original fabric material geometry, and this by a process operating at a temperature mating the characteristics of the polymer and finished fabric material.
- Another object of the present invention is to modify the wetting properties of the surface, to broaden the selection of printing paste and ink materials.
- Yet another object of the present invention is to introduce, into the oxide layer used for stiffening the material, nanometric particle dispersions, even of a metal type, and having such a resistivity as to promote a rejection of atmospheric dust materials and reduce to a minimum a possible accumulation of electric charges, by immediately dispersing the latter.
- the method comprises the further step of surface actuating fibers of fabric materials having an opening from 50 ⁇ m and a fiber diameter from 10 ⁇ m, by a chemical reaction in the presence of an acid which can comprise concentrated H 2 SO 4 or other mineral acid; and then a further step of performing a following treatment by concentrated H 2 O 2 .
- the actuation can also be carried out by a cold-plasma process or treatment.
- the thus processed fabric material is covered by dipping it into the base solution, upon ageing the latter for such a time as to induce rheologic properties suitable to provide a homogeneous covering of the individual fibers, with a covering thickness not larger than 2 ⁇ m.
- the solvent is evaporated off and the deposited material is thermally stabilized, by a thermal process designed as not to modify the original geometry of the fabric material and increase the elastic modulus of the deposited material, with a consequent stiffening of the fabric.
- the base solution can comprise RSiX 3 , where R is an alkyl or aryl, X is an halogen or OR, in a concentration from 5 to 150 g/l SiO 2 (as a rated value), preferably from 20 to 50 g/l SiO 2 (as a rated value) and acidified H 2 O which has been acidified with an acid pH reaction acid, in such an amount as to provide a molar ratio Si/H 2 O at least equal to 2.
- the first solution can comprise S 2 SO 4 , from 10 to 50%, and preferably 20%
- the second solution can comprise H 2 O 2 , from 30 to 120 volumes, preferably 120 volumes, at a temperature from 25°C to 90°C, preferably 40°C.
- the base solution can comprise Al(OR) 3-x (X) x , where R represents an alkyl or aryl and X an organic chelating anion and x can have values from 0 to 1.
- the base solution can comprise Ti(or Zr)(X) x (OR) 4-x , where R represents an alkyl or aryl and X an organic chelating anion, and x can assume values from 0 to 1.
- a second aspect of the present invention provides to stiffen the fabric by using the base inorganic oxide deposit and by controlling the reaction rheology to provide the base solution as the processed fabric is contacted by a mineral acid.
- the molar ratio RSiX 3 /surface active agent is preferably of 1/O.1.
- the stabilizing of the deposit is performed in the final or end method step, by heating the material to cause the solvent to be evaporated off, and complete the chemical reactions of the precursors with water while holding unaltered the geometric arrangement of the fabric material; this can be carried out by a heating process, by using different heating techniques, preferably by IR illuminating or heating.
- the invention provides the advantage that the above disclosed method steps are so performed as to provide a continuous process in a well controlled environment, without interfering against other optional or possible technologies as applied to technical fabric materials for screen printing applications.
- the apparatus for carrying out the above disclosed method comprises a framework 1, including a fabric material T feeding assembly 2, said fabric material T being engaged by cylinders and, through transmission pulleys, being fed to a starting immersion or dipping station 3.
- the fabric material is immersed or dipped into the impregnating solution and then conveyed, through the transmission pulleys 4, to a following impregnating station 5, if the first impregnation is not suitable to provide a sufficient thickness deposit.
- the outlet fabric from each immersion station is then impinged upon by a hot air jet, provided by a blowing device 6, for removing any excess liquid and to facilitate the mesh opening.
- the fabric material is conveyed into an IR beam oven, generally indicated by the reference number 7, where said fabric material is dried and size stabilized, as an end processing step.
- Example 1 the polyethylenglycole terephthalate fabric, having fibers with a diameter of 20 ⁇ m and a mesh opening of 60 ⁇ m, is used in the form of a web having a width of 5 cm, wound up and then distended by pulleys and braking cylinders pertaining to the apparatus inlet assembly 2.
- the actuation is performed by dipping the fabric material into a solution comprising H 2 SO 4 , 10% by weight at 50°C, and with such a sliding speed as to provide a suitable contact between the web and solution, for a time period of substantially 1 minute.
- the outlet web is then immersed into a solution, at a temperature of 25°C, containing 120 volume H 2 O 2 , with a contact time identical to that of the preceding treatment.
- the web is then introduced into a silicon oxide precursor solution upon ageing the latter for 24 hours, correspondingly to the station 3 shown in figure 1.
- the solution is left under a high speed stirring condition obtained by a magnetic stirring device for 2 hours and then a NH 4 O 3 SO(CH 2 ) 11 CH 3 surface active agent is added in an amount of 8 ml/solution liter.
- the solution is left under a high speed stirring condition for further 22 hours, before using it.
- the web is immersed into this solution with such a sliding speed as to assure a contact time between the web and solution of a centimeter/sec.
- the outlet sample is subjected to a hot ventilating air, at a temperature of 120°C, blown perpendicularly to the with of the web, with an air flow rate of a liter/sec for a web meter.
- the web is collected onto spindles and held in web vessels.
- the flexure modulus increase which is thereby obtained corresponds to about 30% with respect to a non-processed fabric material.
- Example 2 the polyester fabric material, including fibers having a diameter of 31 ⁇ m and mesh openings of 50 ⁇ m is used in the form of a web or strip having a width of 25 cm, supplied in a wound up condition and then distended by pulleys and braking cylinders.
- Said web actuated by causing it to pass through an air atmospheric cold plasma, is then introduced into a precursor solution comprising silicon oxide and titanium oxide, which has been subjected to an ageing process for 4 hours.
- the solution is left under stirring (provided by a magnetic stirrer device) for 2 hours.
- the obtained solution is added with a surface active agent NH 4 O 3 SO (CH 2 ) 11 CH 3 in an amount of 10 ml/liter and said solution is held under a high speed stirring condition for 4 hours.
- the web or strip is immersed into this solution with such a sliding speed as to provide a contact time corresponding to 1 cm/minute.
- the outlet sample is processed by processing air at a temperature of 100°C, with an air flow speed and air flow rate designed to subject said web to an air flow of 10 1/meter.
- The, the thus processed web is conveyed to an IR beam dry oven, adapted to bring the sample surface temperature to 300°C.
- the increase of the flexural modulus corresponds to about 120% with respect a non processed web.
- polyester fabric materials can be advantageously used, upon stiffening, for building rotary screen printing cylinders, without using metal fabrics, since hybrid organic-inorganic surface material are used thereon.
- a deposit at the joining weft and warp joining points is such as to advantageously improve the size stability of the fabric material and its resistance against the corrosive action of printing ink and paste materials.
- the covering can be actuated to reduce or fully eliminate dust or powder deposits or for embedding therein other inorganic oxides or metal dispersions, designed for providing the fabric material with very good antistatic, electric conductivity or UV absorption properties.
- Another application field would relate to a modification of the wetting properties, induced by the sol-gel oxide deposit.
- the used oxide precursors, surface active agents or the activation of the surface fibers can be used in any other desired fields, for producing fabric materials based on polymeric fibers having any desired stiffness, mechanical stability, and corrosion and abrading resistance characteristics.
- the stiffening of the screen printing technical fabric by homogeneously depositing thereon inorganic oxides (on the surface of their fibers), does not modify the other features of the fabric material and, in particular, the fabric mesh openings.
- the used materials, as well as the contingent size and shapes can be any, depending on requirements.
