Definitions
- the invention relates to a method of manufacturing a reinforcing thread for interlining. or technical textiles.
- Such threads are intended to be woven or to be inserted in a knit. They are frequently used in articles intended for canvas covering tailors or breastplates. They bring to the products in which they are incorporated their nervousness and their resistance.
- the object of the present invention is a method of manufacturing a reinforcing wire composite, partially synthetic whose structure prevents slipping in the fabric texture or the knit in which it is incorporated, allowing avoid sizing of all textiles or knitting to which it is incorporated.
- second coating fibers are housed in the rough edges formed by the first coating fibers, for example by spinning friction.
- Reinforcement thread for interlining or technical textiles is intended to be incorporated into a textile base.
- this textile base is a fabric
- the reinforcing thread 1 is woven; when the base is a knitted fabric, the reinforcements are incorporated into the mesh system without participate in the training of these. According to the destination of textile, they can be introduced in parallel to the mesh columns or on the contrary perpendicularly to these.
- These reinforcing wires generally have a diameter greater than 10 hundredths of a millimeter.
- the reinforcing thread comprises a synthetic core thread or artificial 2 and the first coating fibers 3 deposited around the synthetic core thread 2.
- the first coating fibers 3 are bonded to the wire core 2 using an adhesive substance 4.
- the wire core 2 is generally monofilament. However, it can also be multifilament.
- the core wire 2 is made of a material synthetic or artificial such as polyamide, polyester or viscose.
- the adhesive substance 4 ensuring the bonding of first coating fibers 3 on the core wire 2 contains a thermosetting polymer. he can also, additionally or alternatively, include a crosslinkable polymer. Bonding can also be obtained using hot melt polymer or fibers associated hot melt in mixture with the first coating fibers 3 or incorporated in parallel over the core 2 at the time of coating.
- the first coating fibers 3 can constitute a wire which is wound around the core wire 2 (figures 1, 3 and 5).
- the coating wire 3 gives relief to the thread 2,3.
- These two wires 2,3 associated by bonding are integral one of the other. The relief of the wire thus produced allows its attachment in the context of the fabric to which it is incorporated and therefore prevents it from sliding.
- the coating wire 3 can be made from fibers short or from filaments.
- the first coating fibers 3 can also be individualized and be associated with the soul thread according to the friction spinning process. These 3 fibers are then glued to the core wire 2 ( Figures 2 and 4). Of this also the first coating fibers give a relief to the wire which allows its attachment in the texture of the fabric in which it is incorporated and prevents it from sliding.
- individualized is used here to describe the condition of the fibers used in the spinning process friction as opposed to fibers that have been subjected to a twist and constitute a wire or as opposed to long filaments.
- the second coating fibers can form a coating wire which is wound in a spiral around the core wire- first coating wire 2, 3 (figure 3).
- the first coating fibers 3 themselves constitute a wire wound in a helix around of the core 2
- the second coating wire 5 forms preferably a propeller of the same pitch. It can be multifilament.
- the first coating fibers 3 constitute a wire ( Figures 1, 3 and 5).
- a coating wire 3 is first wound in a spiral around a core wire 2.
- the equipment allowing the implementation of this manufacturing phase is shown in the figure 6A.
- the core wire 2 is supplied from the coil 6 and the coating wire 3 from the hollow coil 7.
- the core wire 2 is multifilament (2a, 2b), it is composed from several coils such as 6a and 6b.
- the covering pin 8 carries out the winding of the wrapping wire 3 in a spiral around the core wire 2.
- the wire 2, 3, thus obtained, is wound on the reel 9.
- the core wire 2-coating wire 3 assembly is impregnated of an adhesive substance 4 then expressed and dried this which allows the relative joining of these two wires ( Figure 6B).
- the wire 2, 3 supplied from the coil 9 passes through a filled impregnation tank 10 of an adhesive substance 11 comprising a polymer thermosetting and / or a thermosetting polymer.
- the wire 2, 3 is then expressed between the rollers 12, 13 and is then dried during the crossing from the oven 14 and then wound on the coil 15.
- drying used here includes all likely physical or chemical phenomena to occur after bonding to produce adhesion of the coating wire 3 on the core wire 2. In particular, when passing through this oven, the adhesive polymer can crosslink.
- the adhesive substance 4 may include a resin thermosetting, for example acrylic, based on melanin, formalin, polyester, etc ... or polymers crosslinkable by UV radiation.
- a resin thermosetting for example acrylic, based on melanin, formalin, polyester, etc ... or polymers crosslinkable by UV radiation.
- the first coating fibers 3 can be individualized and be associated with the core thread according to the method friction spinning. These fibers 3 are then bonded on the core 2.
- the wrapping phase of the first coating fibers described above ( Figure 3A) is replaced by a coating phase of the first fibers 3 by friction spinning ( Figure 3C). Others process phases are then unchanged.
- the core wire 2 is a large titration wire, for example 300 decitex.
- the first coating fibers 3 constitute a thread of a titration included between 100 and 150 decitex.
- the second coating fibers can be natural, artificial or synthetic in titrations of the order of 0.5 to 9 decitex.
- the spiral formed by the coating wire 3 has preferably of the order of 2 to 5 turns per millimeter.
- the synthetic reinforcing yarn 1 thus obtained does not not slip in relation to the textile texture at which they are incorporated, their touch is mainly determined by the nature of the coating fibers 5 and can therefore be freely controlled. They can advantageously replace the horsehair threads covered.
- the core threads can have great rigidity; the length of the coating wire is greater than that soul thread.
- the coating wire can be smooth.

- La figure 6B représente l'encollage du fil guipé.
- La figure 6C représente l'association des fibres d'enrobage sur le fil par filature à friction.
- La figure 6D représente l'association des deuxièmes fibres d'enrobage par guipage sur le fil.
- Imprégnation des fils avec des polymères liquides en phase solvant.
- Imprégnation des fils avec des polymères thermofusibles amenés en contact en état fondu soit par imprégnation dans un bac maintenu à haute température, soit par filière, soit par pulvérisation.
- Par imprégnation de résines synthétiques ou de polymères sensibles à des rayonnements de type UV, microondes, etc...
- Le deuxième enrobage peut être réalisé avec des fibres discontinues selon la méthode en elle-même connue de la filature à friction ( Figure 6C ). La bobine 15 de fil encollé est utilisée pour alimenter une machine à filer 16 comportant des tambours 17, 18 de filature perforés. Ces tambours sont également alimentés par l'intermédiaire des rouleaux par une mèche de fibres 20, les fibres 20 sont associées à l'ensemble fil d'âme-fibres d'enrobage 2,3 encollé. Les fibres 20 constituent alors les deuxièmes fibres d'enrobage 5 logées dans les aspérités formées par le fil d'enrobage 3 et produisant le fil représenté sur la figure 3. Ce fil, prêt à l'utilisation, est alors enroulé sur la bobine 24. Il est également possible d'introduire des fibres 23 parallèlement à l'âme, avant le dépôt des fibres d'enrobage 5, pour obtenir un toucher de qualité supérieure.
- Les deuxièmes fibres d'enrobage 5 peuvent aussi former un fil qui est lui-même guipé sur l'ensemble fil d'âme-premières fibres d'enrobage 2,3 ( Figure 6D ). L'ensemble fil d'âme-premières fibres d'enrobage 2,3 encollé est alors utilisé pour alimenter une broche de guipage 22 conjointement avec une bobine creuse 23' du fil d'enrobage 3. Après guipage, le fil obtenu est enroulé sur une bobine 24
