Definitions
- the present invention is directed to a textile material which is suitable for use in the substructure of printing blankets.
- Printing blankets are used as important functional components different printing processes used. Due to the high The physical requirements are the construction of such printing blankets preferably multiple layers; it consists of different ones Components.
- the substructure a elastic middle layer (elasticity is when printing Prerequisite) and a top layer.
- the substructure usually consists of a doubled fabric, on which a rubber layer or the like is applied.
- the substructure is responsible for the reinforcement of the Blanket. So far, cotton fabrics have been used for this. Because of the high mechanical stress it requires the stretch of the fabric used is greatly reduced and the force-elongation behavior is narrowly specified, you have the cotton previously extremely stretched, in such a way that a Elongation behavior of ⁇ 1% at 500 N was achieved (web width of the Test piece: 50 mm in the tear testing machine). Such Stretching processes are accompanied by a large loss of width, which can be up to 20% or even 30% depending on the fabric. This means a corresponding loss of final product based on the area of the starting material. They also tend to weave Fibers used to stand out from the ongoing Deform printing process. There is a loss of thickness in the Range of a few hundredths of a millimeter (so-called sinking) what has a negative impact on the printing result.
- the object of the present invention is to overcome the disadvantages of To avoid state of the art and textile fabrics, in particular to provide tissue that as or for the Substructure of printing blankets are suitable.
- the task is accomplished by providing textile Fabric solved, the fibers with an organic film-forming polymers were solidified, the elastic Properties of the fiber material reduced.
- the polymer can by applying an aqueous solution, dispersion, emulsion or suspension of a precursor of the polymer onto the fibers and subsequent networking. preferred Refinements are given in claims 2 to 10. There is also a process for making these textiles Fabric proposed.
- the fibers of the fabric may be more suitable Be connected with each other in a way.
- the material from which the fibers are made is also free selectable, whereby cotton due to the good availability and the other fiber properties is very suitable.
- other fiber materials e.g. based on cellulose or synthetic fibers, where care should be taken to ensure that the crosslinking of the polymer the required temperature is tolerated by the textile material.
- the textile material is treated with the polymer before treatment optionally pretreated in a suitable manner, e.g. washed to Dirt or dust or during production used auxiliaries or coatings such as size or To remove.
- organic film-forming polymer that reduces the elastic properties of the fiber material is intended to encompass those polymers which, if necessary after crosslinking, are able to form a hard film and the property of the fiber to stretch under tension is effective prevent.
- Polymers with a glass transition temperature T g > 0 ° C, especially those with T g > 10 ° C and particularly preferably polymers with T g > 20 ° C are suitable for this.
- the polymers that can be used according to the invention should be able to be applied to the fibers from aqueous systems, since the textile fabric is to be produced for the substructure of printing blankets without organic solvents, in order to pollute the environment in this regard, and to use the necessary additional devices such as suction devices and the like to avoid.
- Polymer dispersions of crosslinkable polyacrylates, polymethacrylates or the like, which impart high hardness and rigidity after crosslinking the fiber, are particularly well suited for the present invention.
- those of one or different monomers can be used for the polymers of the present invention, it being possible to use both homopolymers and copolymers, alone or in mixtures with one another.
- the polymer is preferably applied to the fibers of the textile fabric in such a way that it penetrates into the fiber and envelops it as completely as possible.
- the elongation potential resulting from fiber, yarn twist and possibly fabric incorporation is permanently frozen.
- a relatively low-viscosity formulation of the polymer or of precursors of the polymer, such as monomers or prepolymers is used to impregnate the fiber.
- formulations with a proportion of about 10-60% by weight, preferably about 15-40% by weight, more preferably about 20-30% by weight and very particularly preferably about 25% by weight are suitable.
- Part of solids or part of polymer are commercially available ready for use. It is advantageous to continue adding a wetting agent, since this results in better penetration of the fibers.
- the wetting agent can be present in an amount of a few percent, for example 2% by weight.
- the solution, dispersion, emulsion or suspension of the polymer contains suitable additives such as polymerization initiators for the later crosslinking of the polymers and / or other auxiliaries.
- the rest is solvent, preferably essentially or exclusively water.
- the recipe can be applied on a finishing pad. After applying the mixture, the material, preferably in Tenter frame, dried, e.g. at elevated temperatures.
- the polymer is crosslinked by conventional methods, for example thermally or by exposure to light.
- the textile material to be treated with a Solution, dispersion, emulsion or suspension of the polymer treated which is more viscous than that of the above as preferably mentioned recipe with which penetration of the Fibers is reached.
- the treatment is done here Spread on one side or on both sides of the Fabric, which for this purpose in turn in one Stenter can be clamped.
- fillers such as talc can be added.
- Advantageously contains the formulation also contains a defoaming or deaerating agent. This treatment is preferably carried out unilaterally.
- the recipe can, for example, by means of the air knife method can be applied to the fabric. Then that will Material dried, preferably with increasing temperatures. If thermal crosslinking is provided, the Drying process can be linked to the crosslinking process, by slowly or gradually increasing the temperature required final value is set.
- the aforementioned methods for Polymer application both applied in succession preferably first apply the low-viscosity formulation.
- the textile material is then dried, the polymer but not yet networked.
- the networking of the whole Polymer material can then be dried on one side or higher-viscosity polymer formulation applied on both sides respectively.
- This process variant is only one-sided Treatment with the more viscous polymer solution, dispersion, - Emulsion or suspension often very cheap.
- the textile manufactured as described above Sheets can be calendered if necessary, e.g. to the Set or close the thickness to a desired value to reduce.
- the textile material treated according to the invention is from the inside out more stable than conventionally treated, for the substructure of Textiles treated with printing blankets. This is probably due to the fact that the tissue cavities of the material according to the invention essential parts or completely filled. The mechanical Resilience is improved, e.g. in relation to that Sinking.
- the Printing blankets usually use a doubled fabric. So far, the duplication has usually been done with the help of a Rubber solution in an organic solvent. generally known require operations using organic Solvent special precautions such as separate Exhaust air routing and post-combustion of waste Liquid.
- the present invention will possible to double with the help of a rubber solution waive and replace them with aqueous systems. Because that Textile material treated according to the invention can be conventional laminating machines e.g. with watery Coat and double-layer lamination adhesive. This should be because lie that the polymer applied to others Coating processes promote adhesion.
- this can textile fabrics according to the invention are calendered without that its set thickness changes later, and indeed also over longer periods of time and / or in the case of others Processing steps.
- the calender effect is therefore at substructures according to the invention for printing blankets a permanent one Effect. Even a tentative steaming process that follows the swelling of the fibers favors and thus one Should lead to an increase in thickness has no influence on the Calenders achieved thickness. This results in a series of Benefits. So calendering can be done regardless of location and location Time of printing blanket production and in larger batch sizes done, the final thickness can be planned more precisely, and unnecessary Damage to fibers is avoided.
- Fabric was used that is usually used after the mechanical stretching for the production of printing blankets. It was 100% cotton, Mako super combed with the setting: 19.5 / 21.0 28x2 / 28.0 cm / Nm; made of spliced yarn, knot-free, hand-cleaned and rolled. The fabric width was 262 cm.
- the fabric was washed on a Brugman wide washer. As a result of the cooking shrinkage caused by cotton, the width was reduced to 249 cm.
- the fabric pretreated in this way was treated on a Brückner finishing tenter using the following recipe: 50 Parts Atepol BA 75 from Dr. Th. Bohme 50 Parts of water 2 Parts Lavotan DSU Chem. Factory in Tübingen Atepol B-A75 has a glass transition temperature of 30 ° C.
- the approach was unilaterally based on the air knife method applied the fabric.
- the wet edition was 55g / sqm.
- the Temperature control in the stenter was increasing 120/130/140/150/150/150 ° C until the curing temperature of 150 ° C was reached.
- the overall loss of width due to the treatment was approximately 7.8%.
- Example 1 A fabric made as in Example 1 with a Initial thickness of 0.40 mm was made to a thickness of 0.34 mm calendered. The value remained stable after a rewind 0.34mm thickness. A sample of this product became tension-free steamed, the thickness of 0.34 mm was not changed. The specified maximum thickness of this fabric is 0.35 mm.
- Pre-stretched cotton fabric with an initial thickness of 0.30 mm was calendered to 0.23 mm with line pressure of 250 N / mm.
- the thickness already recovered after a subsequent roll again to 0.28 mm, which is 0.03 mm above the specified Maximum dimensional thickness was.
- the calendering process had to take place immediately before Further processing can be repeated based on lot size.
