Description

The invention relates to a textile support of the knitted mesh type, a method of manufacturing a textile support, a drapery-textile support complex and its method of securing to a second textile.

There are known processes for manufacturing woven mesh textiles. For example, the document GB-A-2097829 describes the manufacture on a screen-making machine of textiles having the same appearance as woven textiles. They comprise a possibly nonwoven substrate, weft threads, warp threads and a sewing thread ensuring the maintenance of the assembly. These different components are chosen to produce an aesthetic effect.

Weft mesh textiles are also used for the manufacture of drive belts (EP-A-0069589) or for the manufacture of reinforcement fabrics (FR-A-2241978).

It is known to cover textile pieces, particularly the drapery in order to improve their support, their volume, to give them greater rigidity or nervousness. The interfacing also makes it possible, in clothing, to carry out the glazing operation which consists in securing a second textile to a drapery with no apparent seam.

According to the traditional technique of mesh or screened mesh, the interlining has a smooth and flat surface both on the back and on the right. Frosting is then a delicate operation which requires very precise positioning of the frosting needle relative to the interlining-drapery complex. Indeed, if the needle is too close to the drapery, the frosting thread crosses not only the interlining, but also the drapery thus letting the seam appear on the outside of the drapery. On the contrary, if the needle is too far from the drapery the icing thread does not catch not the interlining and the desired connection is not achieved.

The object of the invention is therefore to provide a textile support which makes it possible to tolerate a greater variation in the distance between the needle and the sheet during the glazing operation and thereby simplify and make this operation more reliable.

To this end, the invention relates to a textile support of the knitted or knitted mesh type, intended more particularly for the interlining of a drapery, comprising, distributed on at least one of its faces, sections of threads in relief by relative to the free surface of this face, having the function in particular of facilitating the attachment of a glazing wire.

It also relates to a process for manufacturing a textile support of the knitted or knitted mesh type intended more particularly for the interlining of a drapery, in which knitting is carried out and threads are introduced into knitting by means suitable such as guide bars, so that the threads pass on the same side of several rows or throws of stitches constituting the knitted fabric, which has the effect of producing sections of threads in relief and having a float.

It also relates to a drapery-textile support complex of the type comprising a textile support in accordance with that of the invention in which the textile support is applied to and associated with the drapery with its face where there are the sections of threads in relief opposite to the drapery and free.

It also relates to a process for securing a drapery and a second textile by means of a textile support in accordance with that of the invention and a glazing thread in which the textile support is first produced according to the process of the invention, then the support is applied and rigidly associated thus produced with the drapery, in particular by heat-bonding, so that the sections of raised threads are opposite to the drapery and free, then a second textile is applied to the support thus associated with the drapery to form a drapery-support complex, and finally, the second textile is associated with the drapery and, for this purpose, the second textile is applied to the support on the side of the sections of embossed threads and it is secured by glazing, support side, no apparent seam on the drapery side using especially the floats of sections of raised son

The invention firstly relates to a textile support 1 of the knitted mesh type intended more particularly for the interlining of a drapery 2.

The knitting mesh 3 is preferably knitted and these stitches can be woven. It can be used for covering all fabrics or drapery 2.

According to the invention, this knitted fabric 3 comprises, distributed over at least one of its faces, sections of son in relief 4 relative to the free surface 5 of this face.

The free surface 5 is that defined by the stitches of the knitted fabric. The relief of the threads 4 mainly makes it easier to attach a glazing thread 6. It also increases the volume of the knitted fabric.

Preferably, the sections of raised son 4 form over all or part of their length a float 7 having the function in particular of allowing and facilitating the passage of an icing needle 8. The float 7 is the relief obtained on wires 4 when they are not maintained by all the piers 9 under knitting 3.

Preferably, the textile support comprises sections in relief on only one of its faces 10, the other face 11 being substantially smooth and devoid of reliefs.

According to this embodiment, only one face 10 of the textile support 1 is constituted so as to facilitate the attachment of the glazing thread 6 and to increase the volume of the textile support 1, the absence of relief on the other face 11 makes it possible to simplify the fixing of the textile support 1 by this face on a drapery 2 using a fusible 12.

Preferably, the sections of raised son 4 are located close to each other at a distance a of the order of the length of a mesh b.

Preferably, the length of the sections of son in relief 4 is of the order of the length of one to a few stitches b, in particular of the order of two to five stitches.

Preferably, the sections of son in relief 4 are substantially evenly distributed on the textile support 1, each of these two preferred embodiments increases the ease of attachment of the glazing thread in the textile support.

According to a preferred embodiment, the sections of son in relief 4 are produced by son 15 introduced into the knitted fabric 3. In this case, the sections of son in relief with floats 7 can be produced by the passage of these son 15 d 'the same side of several rows or throws 9 of stitches constituting knitting 3.

In this embodiment, the wires 15 are introduced using conventional means. Depending on the desired effects, they may be rectilinear or parallel to the knitting columns of the knitted fabric, or may include jetties below, giving them the desired arrangement. When the threads pass on the same side of several rows or throws 9 of stitches constituting the knitted fabric 3, that is to say throws under these stitches, they acquire a float which gives them the desired relief.

Preferably, the sections of raised son with float 7 are formed from son 15 in the warp direction and between the meshes having a float corresponding to at least two rows or throws 9 of meshes.

This preferred embodiment simultaneously provides a good bond between the son in relief 7 and the knitted fabric 3 and a sufficient relief of these same son 7.

Preferably, the textile support according to the invention also comprises weft threads 16 in the direction of the weft.

In a traditional manner, these screened threads 16 improve the mechanical resistance of the textile support 3. They also help to facilitate the glazing operation and strengthen the resistance of the raised threads 7 to knitted mesh 3.

Preferably, the raised sections 4 of two neighboring wires 17, 18 are offset longitudinally with respect to each other by a length at most equal to the length 19 of the relief of a wire 4.

Thus, whatever the longitudinal position of the frosting needle 8, it will meet during its movement, a thread in relief at a point close to the point the least distant from the drapery.

Preferably, the textile support 1 also comprises on one of its faces 11, opposite to a face 10 comprising sections of son in relief 4, a coating 12 with one or more fusible materials having the function of allowing the use of said support. by heat sealing.

When one wishes to make a textile support 1 having a high density of sections of son 4 in relief, one may find oneself limited by the density of knitting needles of the knitting loom.

In order to exceed this limit, a long frame 16 is used which has a shrinkage capacity during finishing. It is understood that in this way the density of son in relief 4 of the finished product is increased and can therefore be greater than that of knitting needles.

The retraction capacity of the weft 16 is chosen as a function of the final density of the son in relief that it is desired to obtain. The retraction is triggered at the time of finishing, for example by the successive washing, dyeing and heat treatment operations.

The invention also relates to a method of manufacturing a textile support 1 of the knitted or knitted mesh type intended more particularly for the interlining of a drapery 2, in which the knitting 3 is produced and knitting is introduced into the knitting. yarns 15, by means of suitable means such as guide bars, the appropriate introduction means, such as guide bars, are adjusted so that the yarns pass on the same side by several rows or throws 9 of stitches constituting the knitting, which has the effect of producing sections of threads woven in relief and having a float.

The adjustment of the benches with passers during the introduction of threads makes it possible to obtain very varied effects, the number of rows or throws 9 of knit stitches on the same side of which a thread passes is the number of those throws for which the throw - under the weft thread is zero. This number determines the length of the relief c produced by float on the wire 15.

Preferably, a coating 22 is made of the textile support 1 on one of its faces 11, opposite to a face 10 comprising sections of son in relief 4, with one or more fusible materials.

The invention also relates to a drapery-textile support complex of the type comprising a textile support as described above, this textile support being applied to and associated with the drapery with its face 10 where there are the sections of threads in relief opposite to the drapery 2 and free.

The raised sections 4 being on the side opposite to the drapery 2, the drapery-textile support complex benefits from all the properties of the textile support 1 without these being significantly altered during association.

Preferably, the textile support 1 and the drapery 2 are associated with each other thanks to one or more fusible materials 12 of the support 1.

This effective means of connection leaves no trace on the face opposite of the drapery thus not showing the presence of the textile support when the drapery is observed on the side opposite to that where it is located.

Preferably, the drapery-textile support complex comprises at least one glazing thread 6 associated with the support 1 and mainly with the sections of threads in relief 4.

The complex can then also comprise a second textile 20 applied to and associated with the complex by the glazing thread 6.

Thus, the second textile is firmly associated with the drapery via the textile support. The drapery bears no apparent mark of this association thanks to the presence of sections of threads in relief on the textile support.

The invention also relates to a method of securing a drapery and a second textile by means of a textile support as described above and of an icing thread in which the textile support is produced according to the method also described. higher, then apply on and rigidly associate the support 1 thus produced with the drapery 2, in particular by heat-bonding, so that the sections of raised threads 4 are opposite to the drapery 2 and free, then apply on the support 1 thus associated with the drapery 2 to form a drapery-support complex a second textile 20 and, finally, the second textile 20 is associated with the drapery 2 and, for this purpose, the second textile 20 is applied to the support 1 of the side of the sections of son in relief 4 and a bonding by glazing is ensured, support side, no apparent seam on the drapery side using more particularly the floats 7 of sections of son in relief 4.

This joining is thus achieved without appearing in any way on the free side of the drapery. Each of the components of the complex produced and particularly the textile support contributes to giving all of the properties such as volume, suppleness and nervousness.
