Definitions
- the invention relates to a coated fabric with a fabric made of endless multifilament threads, which is coated with two layers of macromolecular substances, a method for its production and its use.
- a coated fabric is known from BE-PS 543 880.
- Coated fabrics generally consist of a fabric, knitted fabric, scrim or the like thread structure, or the like with rubber, plastic, resin. is coated, and are usually liquid and air or gas impermeable.
- the advantages which can be achieved with such coated fabrics can be attributed in particular to the combination of the known favorable properties of the conventional coating materials with the comparatively higher strength of the thread structures embedded therein.
- coated fabrics are widely used in a wide variety of areas of technology and everyday life, for example for the manufacture of air-filled halls, stadium roofs, packaging material, truck tarpaulins, inflatable boats, roof truss insulation and the like.
- difficulties arose again and again, especially when the adhesion between the fabric and the coating material was insufficient.
- Better adhesion is generally achieved with fabrics made from spun yarns, which is why such fabrics were often preferred, so that the known advantages of endless multifilament yarns could not yet be fully applied in all areas.
- fabrics with a high fabric density could be used.
- the present invention is therefore based on the object of providing a coated fabric in which the adhesion between the fabric consisting of endless multifilament threads and the coating composition consisting partly of synthetic resin is improved such that due to the improved adhesion and the comparatively higher Strength of multifilament continuous filaments, even fabrics with a lower fabric density than previously customary.
- a coated fabric with a fabric made of endless multifilament threads which is coated with two layers of macromolecular substances, in which, according to the invention, the surface of the endless multifilament threads is activated and roughened to improve the adhesion by chemical action, in which the tissue has a fabric density in the range from 26% to 60%, and in which the first and second layers consist of a plastic / synthetic resin mixture, the proportion by weight of the two mixture components being different in the two layers.
- the nature of the first layer ensures excellent adhesion to the carrier fabric, and despite the presence of the second layer, the coated fabric according to the invention has a high degree of flexibility.
- the nature of the second layer makes it possible to process the coated fabric according to the invention as such or to make it usable for other purposes by further coating.
- the present invention therefore makes it possible, using the known advantageous properties of endless multifilament yarns, to keep the proportion of fabric comparatively low without having to accept any loss in the performance properties of the coated fabric according to the invention.
- a further improvement in the adhesion between the fabric and the first layer is achieved if the fabric or the threads used for this purpose previously according to one of DE-AS-1 199 224, DE-AS-1 212 245, DE- OS-1 444 139, DE-AS-1 444 140, DE-OS-1 444 141 or DE-AS-1 444 142 have been treated.
- both sides of the fabric can also be coated with the same advantages.
- fabrics with a relatively high fabric density of, for example, 60% are suitable, as well as fabrics with a relatively low fabric density of, for example, 26%.
- fabrics with a relatively low fabric density of, for example, 26% are suitable, as well as fabrics with a relatively low fabric density of, for example, 26%.
- particularly good results are achieved with fabrics whose fabric density is in the range from 32% to 42%.
- the method described in the magazine “Textilpraxis", edition 1947, pages 330 to 335 and 366 to 370 is used to determine the fabric density.
- the proportion by weight of the plastic in the first layer or in the second layer is only 0.2 times or 10 times the proportion by weight of the synthetic resin in these layers
- the proportion by weight is Plastic in the first layer and / or in the second layer but advantageously 1 to 4 times the proportion by weight of the synthetic resin, excellent results being achieved when the proportion by weight of the plastic is 1.5 to 2 times the proportion by weight of the synthetic resin.
- the synthetic resin contained in the first and / or in the second layer is a phenolic resin and / or the plastic contained in the first and / or the second layer is elastic and / or thermoplastic.
- a sufficiently high dimensional stability even under tensile stress is achieved if the fabric used has a not too high reference elongation.
- Good results are already achieved with the coated fabric according to the invention when the reference elongation of the fabric, measured at 55 daN / 5 cm, is below 4% and measured at 90 daN / 5 cm below 8%, although a fabric is preferred in which the corresponding values are below 2% or 4% and excellent results can be achieved if these values are below 1% or below 2%.
- the reference strain is taken directly from the usual stress-strain diagram of the tensile test according to DIN 53 857 or 53 354.
- the advantageous properties of the coated fabric according to the invention are possibly further improved by the fact that at least the second layer contains conventional inorganic fillers with a weight fraction of up to 80% of the respective layer.
- conventional inorganic fillers for example, CaCO z.
- Fabrics in the sense of the present invention are all known fabrics made of fibers and / or threads, for example conventional fabrics, fleeces, laid fabrics, knitted fabrics and the like, the fabric most suitable for the respective purpose being determined quickly and easily by producing appropriate test pieces can be.
- the fabrics suitable for producing the coated fabric according to the invention generally need not have been subjected to any special pretreatment that goes beyond the usual. However, it is readily possible to use fabrics whose fibers have previously been activated and roughened by chemical action on their surface.
- thermosets are highly cross-linked thermoset materials produced by polymerization, polycondensation or polyaddition, also called thermosets, which also include hardeners, plasticizers, catalysts and the like. may have been added.
- synthetic resins are: polyamide, phenol, unsaturated or saturated polyester, epoxy or acrylic resins.
- plastics are weakly crosslinked dispersible thermoplastic substances which are produced by polymerization, polycondensation or polyaddition and which, after drying, i.e. after removal of the dispersion liquid, for example water, preferably have a rough surface structure.
- plastics based on the following are suitable: acrylic, acrylic acid esters, acrylonitrile copolymers, polyvinyl acetate, epoxy and the like.
- the synthetic resins and plastics suitable for the coated fabric according to the invention can also be chemically related, i.e. belong to the same chemical system.
- the flexibility or rigidity of the coated fabric according to the invention can be adapted to the respective requirements by a suitable choice of the mixing ratio of plastic and synthetic resin in the coating mixtures.
- the first layer acts as an elastic film former with good film formation on the carrier fabric, so that the second layer is prevented from penetrating too deeply into the carrier fabric, as a result of which a high flexibility of the coated fabric according to the invention is achieved.
- the determination of the plastic or synthetic resin content in the two layers of a sample is possible, for example, by making several sample strips with different proportions of the two mixing partners and then carrying out comparative measurements on the sample and the sample strip.
- the customary and known methods can generally be used, in which the layers are coated in succession by doctoring, by application rollers, in immersion baths and the like. are applied in succession to the carrier fabric, wherein after the application of a layer, this layer is optionally dried in whole or in part and / or is allowed to set or harden.
- the carrier fabric can be subjected to a chemical treatment beforehand, by means of which the threads or fibers used for the carrier fabric are activated and roughened on their surface.
- the mixtures intended for the two layers preferably consist of a mixture of an aqueous colloidal plastic dispersion and a water-soluble synthetic resin and the appropriate chemical reactant.
- a mixture consisting of an acrylic-based plastic, in particular acrylonitrile and acrylic acid ester copolymers, and a water-soluble synthetic resin based on phenol-formaldehyde has proven particularly useful.
- Fillers can also be added to the layer mixtures. Depending on the type and amount of the particularly preferred inorganic fillers, the application of the first layer on the top and bottom of the fabric may be appropriate.
- customary wetting agents can also be added to the mixtures intended to form the two layers.
- the roughening and activation of the thread surface is usefully achieved when the mixture intended for the first layer has a pH in the range from 8 to 14 and that the mixture intended for the second layer is adjusted to a pH in the range from 7 to 14.
- This can be achieved, for example, by adding an appropriate amount of sodium hydroxide solution (NaOH) or ammonia (NH3) to the plastic / synthetic resin mixture.
- NaOH sodium hydroxide solution
- NH3 ammonia
- the alkalinity of the mixture intended to form the second layer can in this case be set to an equally high or even higher pH than that of the mixture intended for the first layer, but it is preferably set to a lower pH.
- the coated fabric according to the invention can be used in a variety of different ways due to the excellent adhesion between the base fabric and the coating material, as well as its great flexibility, high strength and low reference elongation. Because of the advantageous properties mentioned, it is also particularly suitable for the production of all types of abrasives, which can advantageously be used for both dry and wet grinding processes, the coated fabric according to the invention also being outstandingly suitable for producing endless grinding belts. When using the coated fabric according to the invention for the production of abrasives, it has a particularly advantageous effect that an excellent adhesion of the grain binder layer to the second layer is achieved.
