Definitions
- the present invention relates to an improvement made to Jacquard knits made on a circular double-knitted loom needle bed usable in particular as covering materials for seats, walls ..., especially in the interior trim sector vehicles (see GB-A-2 263 485).
- It relates more particularly to a new type of knitting obtained on a circular knitting loom, double needle bed.
- Such knitting looms consist essentially of a tray horizontal and a vertical cylinder, one of these, usually the cylinder (also called vertical needle), which allows you to select the needles according to a predetermined rhythm according to the drawings which one wish to achieve.
- the horizontal bed or tray has a combined cam track as for Interloc trades, capable of selecting the needles so that each row of the wrong side, made with the thread forming the right side, either obtained on two successive falls. Therefore, when we make a Jacquard three colors, each row of knitting is done by making a selection from the cylinder drawing, so that all the needles work to make a row of knitting which is therefore done from three scraps, while the wrong side which is knitted on the needles of the tray has a structure such that each row formed with the same wires that those forming the drawing is carried out on two successive falls, this which therefore results in a density of this reverse 1.5 times that of the place.
- each row is made from of four falls, the reverse made with the needles of the tray being always made on two successive falls, which leads, in such a case, to a density of rows of stitches on the reverse double that obtained from the right side.
- the new Jacquard knit three or four colors according to the invention is characterized in that the knitting weave for producing the reverse side is unstructured compared to a conventional weave, the article obtained having the same density of stitches on the reverse with respect to the place in the case of a Jacquard four colors and, in the case of a Jacquard three colors, a density equal to 0.75 times that of the place.
- the destructuring is obtained by leveling the loom every other needle, thereby halving the number of columns of meshes on this face and therefore by two the density of meshes.
- the plate armor is performed by staggering selecting one needle out of four, allowing to halve the number of rows, so also the density of stitches by two.
- Such a staggered selection of needles can be obtained by making the armor of the plate on four cam tracks. He could also be considered to carry out such a selection by means of a Jacquard system associated with the tray.
- Figures 1 and 2 illustrate the structure of a knitted fabric Jacquard three and four classic colors.
- Figures 3, 4, 5 and 6 illustrate four Jacquard knits produced according to the invention, Figures 3 and 4 corresponding to a knitted fabric Jacquard three colors and Figures 5 and 6 to a Jacquard knit four colors.
- the needles are selected so that the falls (1,2,3) give a row, and the falls (4,5,6) a second row.
- the density of the reverse side is one and a half times greater than that of the front panel.
- Figures 3 and 4 illustrate the structure of a Jacquard three knit colors obtained in accordance with the invention.
- the falls (1) and (2) give a first row, (3) and (4) a second row, (5) and (6) a third row.
- Such an article presents, compared to that illustrated in FIG. 1, a density in column of meshes divided by two.
- FIG. 4 illustrates the rebalancing of a knitted fabric by destructuring by plate knitting with four cam paths or by selection Jacquard.
- the armor ratio is twelve falls, four rows in the cylinder forming the Jacquard face side corresponding to only three rows on the tray.
- Figure 5 illustrates a four-color Jacquard knit produced in accordance with the invention, the destructuring on the reverse side being obtained by knitting on the plate on four cam paths or by Jacquard selection.
- the falls (1,2,3 and 4) give a row to the cylinder and also a row on the tray, the mesh density being therefore identical on reverse and place.
- Figure 6 illustrates the realization of a Jacquard four colors whose destructuring of the reverse side is obtained by planing of the plate of a needle on two.
- the falls (1,2,3,4) give a row to the cylinder
- the falls (1) and (2) giving as for a first row to the plateau and the falls (3) and (4) a second row.

Description
Claims (5)
- Tricot Jacquard trois ou quatre couleurs réalisé sur un métier circulaire à mailles cueillies, caractérisé en ce que l'armure de tricotage constituant la face envers est déstructurée par rapport à une armure équivalente conventionnelle, ledit tricot présentant la même densité de maille sur l'envers par rapport à l'endroit dans le cas d'un Jacquard quatre couleurs et, dans le cas d'un Jacquard trois couleurs, une densité égale à 0,75 fois celle de l'endroit.
- Procédé pour la réalisation d'un tricot Jacquard selon la revendication 1, caractérisé en ce que la déstructuration de la face envers est obtenue en déjaugeant le plateau du métier d'une aiguille sur deux, divisant ainsi par deux le nombre de colonnes de mailles sur cette face et donc également par deux la densité des mailles.
- Procédé pour l'obtention d'un tricot Jacquard selon la revendication 1, caractérisé en ce que l'armure du plateau constituant la face envers est réalisée en sélectionnant en quinconce une aiguille sur quatre, entraínant une division par deux du nombre de rangées sur la face envers et, en conséquence, une densité de mailles divisée par deux.
- Procédé selon la revendication 3, caractérisé en ce que la sélection en quinconce des aiguilles est réalisée sur quatre chemins de came.
- Procédé selon la revendication 3, caractérisé en ce que la sélection en quinconce des aiguilles est obtenue par l'intermédiaire d'un système Jacquard.
