Definitions

  • the present invention relates to a textile sheath for acoustic protection
  • the invention relates to protective envelopes such as sheaths in woven, knitted or braided fabric, which make it possible to protect products subjected to vibrations, creating an undesirable noise. More particularly, the present invention applies to products of the sheath type suitable for covering elongated elements such as metal wires or cables, possibly arranged in bundles.
  • Such textile sheaths are commonly used in the automotive industry where they allow metal wires or tubes to be enclosed in confined spaces
  • This sheath makes it possible to protect and wrap bundles of pipes, tubes or electrical wires used in conditions of significant abrasion and vibration, in a confined space, inside the door of an automobile for example.
  • This sheath is formed of a first thread of the multifilament type and of a second thread of the monofilament type, the two threads preferably being combined by knitting or braiding. Such sheaths fit correctly on the bundles of threads and provide good absorption. acoustic vibrations
  • the present invention aims to provide a textile sheath allowing improved acoustic protection
  • the textile acoustic protection sheath targeted by the invention comprises yarns of a first type comprising a monofilament and yarns of a second type comprising a multifilament
  • the sheath is formed of a textile structure having an asymmetrical distribution of the son of the first and second type on both sides of the sheath Thanks to this asymmetrical distribution of the two types of son, each of the two types of son can be preferably placed on one or the other of the faces of the sheath, according in particular to its physical and mechanical characteristics.
  • the wires of the first type are mainly distributed on an inner face of the sheath and the wires of the second type are mainly distributed on an outer face of the sheath
  • the monofilament which is mainly used to give its shape to the sheath, is present inside the sheath II is intended to come into contact with an element to be protected, such as a bundle of wires, and allows the sheath to properly marry this item
  • the multifilaments which mainly confer on the sheath its vibratory absorption characteristics, are mainly arranged outside the sheath.
  • the textile structure is a woven structure having an asymmetrical distribution. weft threads and warp threads on both sides of the sheath.
  • the woven structure has an offset in a direction perpendicular to the weft threads of the bindings of a warp thread to a neighboring warp thread
  • FIG. 1 schematically represents a portion of textile sheath according to the invention
  • FIG. 2 schematically illustrates the right side of a textile structure used for a sheath in accordance with a first embodiment of the invention
  • FIG. 3 schematically illustrates the right side of a textile structure used for a sheath in accordance with a second embodiment of the invention
  • - Figure 4 illustrates a textile sheath for acoustic protection according to the invention mounted on a bundle of wires
  • FIG. 1 A portion of textile acoustic protection sheath according to the invention is illustrated in FIG. 1
  • This textile sheath 10 comprises two types of yarns
  • the yarns of the first type 1 1 comprise a monofilament while the yarns of the second type 12 comprise a multifilament
  • monofilament yarns are conventionally used for their elastic property, while multifilament yarns are used mainly for the attenuation of vibrations, and in particular the acoustic protection of the elements housed in the sheath
  • the sheath 10 is formed of a textile structure which has an asymmetrical distribution of the son of the first type 1 1 and the son of the second type 12 on both sides of this sheath 10
  • the textile structure is a woven structure having an asymmetrical distribution of these weft threads and warp threads
  • Such an asymmetrical distribution is obtained for example for a woven structure with twill weave as illustrated in FIG. 2
  • the weft threads 1 1 are shown horizontally while the warp threads 12 are shown vertically
  • the twill weave is characterized in particular by the fact that the binding of a first warp thread is repeated on a second neighboring warp thread with an offset of one pick (portion of weft thread 1 1 between the edges of the fabric) , in a direction perpendicular to the weft yarn This offset is thus repeated from warp yarn to neighboring warp yarn
  • a twill weave fabric thus has oblique stripes on the right side of the fabric, called "ribs"
  • a twill of 4 has been illustrated here (the tying pattern is repeated on each group of four neighboring warp threads) with warp effect, that is to say that the warp threads 12 predominate over the place of the fabric.
  • the woven structure could also have a satin weave
  • the woven structure with satin weave is distinguished by the presence of a constant offset in a direction perpendicular to the weft thread 1 1 of the bindings of a warp thread 12 to a neighboring warp thread 12
  • This notch indicates by how many picks the crossing point or binding is moved up between two neighboring warp threads 12, from left to right on the right side of the fabric.
  • a satin of 5 the tying pattern is repeated on each group of five neighboring warp threads
  • a check mark of 3 the check mark of 3 and with warp effect
  • the weft threads 1 1 are threads of the first type comprising a monofilament and the warp threads 12 are threads of the second type comprising a multifilament
  • the yarns of the second type or warp yarns 12 are mainly located on the place of the woven structure, intended to become the outer face of the sheath
  • the yarns of the first type or weft yarns are mainly distributed on the back of the woven structure, intended to become the inside of the sheath
  • the son of the first type 11 here consist of a single thermoplastic monofilament.
  • This monofilament gives the sheath its elastic appearance as well as a self-closing appearance as will be described below.
  • This monofilament can be made of polyester, polyamide, polyethylene, polypropylene, polyketones, polysulphone or any other polymer or a mixture of these.
  • the diameter of this thermoplastic monofilament is between 0.1 and 0.5 mm, and preferably between 0.15 and 0.30 mm.
  • the first type yarns 11 can comprise, in addition to this monofilament, one or more other monofilaments or multifilaments.
  • the yarns of the second type 12 comprise at least 80%, and preferably 100%, of multifilaments.
  • These multifilament yarns provide good attenuation of acoustic vibrations, and also give the textile a characteristic
  • the multifilament can be composed of natural or artificial material or of a mixture of the two according to the applications of use of the textile sheath.
  • a textured multifilament will be used in order to increase its bulk to better attenuate the vibrations.
  • this textile sheath 10 forms a tubular sheath obtained by forming a textile structure woven flat.
  • An open sheath 10 is thus obtained, self-closing thanks to a covering portion 14 as illustrated in FIG. 4.
  • This open and self-closing sheath structure facilitates the positioning of this sheath 10 around bundles of elongated elements 13.
  • ends 10a of the textile sheath 10 are preferably cauterized by hot cutting.
  • the sheathing can be cut to length, after forming, by cutting it by means of a heated blade, for example by passing an electric current
  • the textile sheath thus obtained in accordance with the invention makes it possible to obtain a distribution of the monofilaments 1 1 preferably located inside the sheath, on a face adapted to come into contact with the bundles of elongated elements 13 to be protected.
  • the multifilaments 12, whose bulk and volume make it possible to significantly attenuate the acoustic vibrations, are arranged on the outer surface of the sheath 10
  • This sheath 10 thus offers better resistance to abrasion and to the attachment of its surface.
  • the textile sheath according to the invention makes it possible to significantly increase the acoustic protection of the elements in bundles.
  • a sheath having an asymmetrical textile structure in accordance with the invention makes it possible to obtain attenuations greater than 43 dB (A)
  • any type of asymmetrical woven weave can be used to make the sheath, and in particular other serges or satins than those described
  • the textile sheath obtained with such a structure is more resistant to abrasion and to the risks of snagging, in particular during its installation.
  • the textile sheath could possibly be woven in a tubular form
