Definitions

• the invention relates to a textile material web for the production of truck tarpaulins or the like.
• a carrier consisting of polyester, polyamide or polypropylene fibers, which has at least one side over its entire surface with a meltable polyolefin co or terpolymer or the like. is coated.
• Tarpaulins are generally known, the backing fabrics of which are provided on both sides with polyvinyl chloride coatings. Coatings of this type are inexpensive and easy to produce, and the various tarpaulin requirements can be met, such as cold resistance, resistance to kinking and fluttering, resistance to rotting, soiling behavior and weld seam strength.
• the surfaces of these known polyvinyl chloride coatings can largely be influenced as desired, namely in the sense of a handsome appearance per se and in the sense of painting or lettering and the like.
• polyvinyl chloride is a problematic substance in that the parts made from it release hydrogen chloride in the event of a fire, which forms hydrochloric acid with atmospheric moisture. The fire thus leads to considerable pollution of the environment and no longer disposal The required polyvinyl chloride parts or tarpaulins are accordingly difficult.
• the coating is carried out in such a way that a polymeric welding compound, namely ethylene-vinyl acetate copolymers, polymers from the group of polyvinyl chloride or the like. can be used by only being introduced into the hollow curves of a textile structure of the carrier, where they form a welded joint when heated. Bulges of the textile backing, namely the humps of the threads, remain free of coating material. The welded joint area therefore extends over the entire surface of the beam, but does not cover the entire surface, so that welded joints of sheet material do not always show the desired bond strengths.
• a polymeric welding compound namely ethylene-vinyl acetate copolymers, polymers from the group of polyvinyl chloride or the like.
• coating is carried out by applying the plastic, ie the layer-forming substance, in the form of a paste using known coating and spraying devices.
• the formation of the layer is thus in a known manner dependent on the consistency of the paste and the devices applied to it.
• the invention is therefore based on the object of improving a material web with the features mentioned at the outset so that, in particular, the requirements for a permanent connection between the carrier and a halogen-free coating are ensured.
• the meltable plastic which is used to produce a coating
• the full-surface melt results in a very intensive connection with the carrier, because the plastic melt due to the high pressure, for example when removing from the rollers, can penetrate deeply between the fibers of the carrier, which contributes to the desired permanent connection of this plastic to the carrier.
• the resulting full-surface connection between the plastic melt and the carrier consisting of plastic fibers is made possible above all by the fact that with the co-polymers or terpolymers mentioned a higher density results in a falling crystallinity, which means multi-polarity and therefore better adhesion and enables high-frequency welding .
• the coating is soft due to selected co- or terpolymers corresponding to the elastic modulus of the type and can therefore be used as a tarpaulin.
• the material web is formed in such a way that the polyolefin co- or terpolymer is wholly or partly by polar and reactive polyolefin terpolymers, namely: Ethylene acid / maleic anhydrite terpolymers, Ethylene ester / maleic anhydrite terpolymers, Ethylene ester / glycidil methacrylate terpolymers, is replaced.
• the functionalization of the ethylene ester or of the ethylene acid with maleic anhydrite or glycidil methacrylate additionally creates reactive groups which additionally have favorable effects on the adhesion and / or the paintability.
• the above-mentioned copolymers or terpolymers are mixed to match the individual case. If, for example, the weld seam strength has to be observed at high temperatures, only products with a Vicat temperature greater than 70 o are suitable.
• the acrylic derivatives of ethylene are advantageously butyl or methyl acrylates. Depending on the type and proportion of the derivative, special adjustments can be made.
• meltable plastics mentioned can therefore be mixed in certain proportions in order to meet the requirements for softness, temperature resistance, etc. They can be mixed with substances that influence the properties of the material web, such as thermal, light and UV stabilizers, color pigments, fillers, antioxidants, halogen-free flame retardants, antiblocking agents or mold release agents.
• Coating with the melt can be carried out directly by means of slot die extruders, melt rollers or calenders. It has been found that the meltable plastics mentioned adhere only so well to the roller or to the application member in accordance with the melt index that they can be transferred to the carrier even in thin layers.
• the meltable plastic used to produce the coating is melted in a known manner, in the case of calender or melt roll coating, by melting in the roll nip directly or beforehand in appropriate preparation machines.
• the textile carrier consisting of polyester / polyamide or polypropylene thus consists of fibers that are held together in the usual way, for example as a nonwoven or woven fabric, knitted fabric or scrim.
• plastic fibers means both mono- and multifilament elements. Their use and processing are based on the requirements to be met by the wearer with regard to strength or connection strength with the coating material.
