Definitions
- the invention relates to a transfer tube, which is used in particular at high temperatures.
- Transfer hoses are flexible hoses that come with an outer layer
- Such hoses may comprise multiple layers or layers
- the outer layer of reinforcements may be in the form of a braid, knitted fabric, knitted fabric, woven fabric or the like.
- Textile transfer hoses are often used in the low-pressure area and / or in the
- Low temperature range ( ⁇ 150 ° C), z. Eg as fuel. Oil or compressor hoses used.
- For the high temperature range (> 150 ° C) usually hoses are used, but due to the necessary high-quality additional outer layer have a significant cost and weight penalty.
- a Umlageschlauch is described, which is characterized by a high dynamic lifetime performance even under high movement and especially at high temperatures (> 150 ° C).
- the materials mentioned there for the levy of the Umlageeschlauches can be used as a hybrid yarn, in which two yarns are each made of a different material to a twisted yarn, see Fig. 1st
- the individual yarns of this Mischgeflmüs have different physical properties, resulting in an inhomogeneous behavior, such as different Garnschrumpf, different elongation, different tensile strength, etc. results. Furthermore, the mixing ratios are limited in these mixing braids.
- the object of the invention is therefore to provide a transfer tube, which is further characterized by a high dynamic
- Temperatures (> 150 ° C) is characterized, and at the same time within the levy shows a homogeneous behavioral profile with respect to the physical properties.
- the charge of the Umsetzeschlauches contains at least one yarn of a textile pulp, which consists of at least two fibers which are different from each other.
- Such a yarn is also referred to below as mixed fiber yarn.
- the charge of the transfer tube is completely composed of at least one composite fiber yarn, which consists of at least two fibers which are different from each other.
- a twist can be produced in a further preferred embodiment, so that the charge of the transfer hose either from
- the mixed fiber yarns for producing the twist may in this case be the same or different from one another.
- a thread is a line-shaped textile structure which has been produced by twisting (twisting) at least two yarns. There are one-step and two-step threads and two-fold and multiple threads.
- a yarn is a line-shaped structure which consists of textile fibers, for.
- staple fibers which are also referred to as staple fibers, filaments or tapes, etc. is produced.
- a monofilament is a yarn from a
- Filaments are each referred to with or without rotation, wherein the individual filaments can have a diameter of about 0.1 mm.
- monofilament and monofilament yarn can therefore be used interchangeably for monofilament, practically endless fibers.
- Staple fibers here have a limited length, while filament fibers are endless, see also ISO 8159: 1987.
- the levy can be formed here as felt, fleece, fabric, braid, knitted or knitted fabric, scrim. It is also possible that the contribution from various components of felt, fleece, fabric, braid, knitted or knitted fabric, scrim is formed. It is preferably woven fabric, in which the surface is made by crossing two thread systems, namely warp and weft, or a knitted fabric, in which a loop formed by means of thread in another loop is looped in and the stitches thus formed can be formed using one or more threads.
- the charge is preferably a woven fabric, in particular a woven fabric, warp and / or weft, preferably warp and weft, can be used for this purpose
- the transfer is a knitwear, in particular a knit fabric, in which either at least one thread of the knitted fabric, but preferably the entire knit fabric, consists of the mixed fiber yarn and / or of the twine produced therefrom. Staple fibers are preferably used for the mixed fiber yarn.
- the material for the mixed fiber yarn is preferably selected from the group consisting of polyester (PES) and / or polyphenylene sulfide (PPS) and / or polyoxadiazole (POD) and / or aramid (AR) and / or polyimide (PI) and / or polyetheretherketone ( PEEK) and / or polyethylene-2,6-naphthalate (PEN) and / or polyphenylene (PPP) and / or polyphenylene oxide (PPO) and / or polyphenylene ether (PPE) and / or polybenzoxazole (PBO) and / or carbon fibers (CF) and / or glass fibers (GF) and / or Cotton (CO) and / or metal fibers (MF) and / or rock fibers, such as. Basalt fibers, and / or cellulose and / or modal and / or ceramic fibers.
- PES polyphenylene sulfide
- POD polyoxadiazole
- PES / m-aramid or PES / p-aramid has proven particularly suitable.
- Diesel Particulate Filters DPF
- transmission and engine cooling or in areas where aggressive media must be transported at high temperatures.
- the transfer tube may in this case in straight or in a molded version, e.g. be used as a hose manifold.
- hoses may contain a plurality of layers or layers of different elastomers, thermoplastic elastomers or thermoplastics.
- surcharge still one or more embedded
- Reinforcing layers be present.
- all known to the expert person strength materials can be used.
- thermoplastic elastomers in principle, all elastomers, thermoplastic elastomers or thermoplastics can be used according to the invention. Preference is given to elastomers, thermoplastic elastomers or thermoplastics which have a temperature resistance of greater than or equal to 150 ° C.
- the elastomers are, for example, selected from the group consisting of:
- HNBR hydrogenated nitrile rubber
- FKM fluoro rubber
- ECO polyepichlorohydrin
- EVA ethylene-vinyl acetate rubber
- ACM acrylate rubber
- AEM ethylene acrylate Rubber
- Temperatures can be achieved using HNBR, FKM, FPM, ACM, AEM, and / or silicone rubber, with FKM, FPM, and AEM being particularly well suited.
- the elastomers mentioned can be used alone or as a blend with at least two elastomers.
- thermoplastic elastomers in the blend with thermoplastic elastomers and / or thermoplastics.
- thermoplastic elastomer is preferably at least one thermoplastic elastomer with polycarbonate component (TPE-C) use.
- the transfer hose can additionally be equipped with a rigid reinforcement, as known, for example, from EP 202 436 A2 for hoses with an (elastomeric) cover layer.
- the rigid reinforcements are preferably monofilaments, also referred to as monofilaments, which are wound in the same direction or in opposite directions around or in the levy.
- the monofilaments can also be wound crossed.
- the monofilaments may be constructed of a metallic, such as stainless steel, or a non-metallic material, such as. PPS or POD. That the material of the rigid reinforcement can in this case be the same or different from the material of the levy.
- the levy is, as already mentioned above, applied as a textile fabric in the form of braid, cord, knitted fabric, knitted fabric, fabric, felt, nonwoven or scrim, wherein preferably the application takes place as a braid.
- the coating layer can be formed in one or more layers.
- the overlay layer preferably has 1 to 5 layers, particularly preferably 1 to 3 layers and very particularly preferably 1 to 2 layers.
- the levy i.
- a protection can be applied, which protects the fibers from external influences, such as.
- the reinforcements can also be completely or partially colored, for example by spin dyeing, cross-dyeing or strand dyeing. This is used, inter alia, for optical identification. Furthermore, subsequent surface functionalization, for example with RFL or fluoropolymer solutions, possibly in combination with a dyeing, is possible. On the one hand, this layer protection serves as a cut protection, which prevents the fraying of the interface, on the other hand, the adhesion between fiber and
- test results show the change in the bursting pressure, according to EN ISO 1402, section 7, hydrostatic test, of a coating tube with a coating layer according to the invention in respectively different fiber material ratios. After aging for 42 days at 150 ° C., a very low degradation value is found especially in the combination of PES / PPS.
- Figures 1 to 3 each show different Garn injuredten.
- the fibers shown schematically in white here consist of a different material than the fibers shown schematically in black.
- Fig. 1 shows a hybrid yarn of the prior art, consisting of two different yarns, each completely made up of a different material. shows a Mischmaschinegarn, which consists of at least two fibers which are different from each other.
