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 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

  • 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.

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
