Definitions

  • the invention relates to a foldable articulated fabric without permanent crease as well as a blind made with said articulated fabric. It will find its application in particular in the weaving industry in particular of textile materials and others.
  • the very structure of the fabric gives it particularly appreciable flexibility properties in many uses.
  • a fabric naturally has no particular folding axis and, if necessary, a permanent fold can be produced artificially, for example using pleating, using a hot iron and steam to fix a permanent fold.
  • Folding can therefore be localized but the direction of folding cannot be indifferent which can constitute a significant handicap for certain applications.
  • blinds for example, these are currently made up of lamellar systems connected by a cord device which serves to connect them.
  • the manufacture of this type of article is unitary and therefore its cost is high.
  • a folding zone in a slatted blind requires that the structure of the blind be produced by an assembly of semi-rigid planar elements connected by auxiliary hinges. It is indeed essential that in the deployed position, the blind has a flat surface without creases and therefore the pleated fabrics mentioned above cannot be suitable for this use because their deployment cannot be achieved without a fold.
  • the main object of the present invention is to present a folding articulated fabric without permanent pIi which can be made continuously by traditional weaving of threads formed from any materials.
  • the absence of permanent folds has many advantages, in particular that prevents the fabric from being wrinkled.
  • the possibility of using materials of any kind for the production of the fabric of the present invention considerably widens the field of application thereof.
  • the articulated fabric of the present invention retains a homogeneous structure and therefore from an aesthetic point of view the fabric of the present invention is particularly attractive since it retains the continuous appearance of the fabrics.
  • the articulation of the fabric is localized and therefore there is no fear of malformations in the folding since it is self-controlled by the very structure of the fabric.
  • the joints of the fabric have no meaning unlike the pleating traditionally used until now. No retaining force is encountered and the deployment of the fabric can be obtained in a perfect manner to obtain a flat panel having no pleating defect.
  • Another object of the present invention is to present a blind which can have sunshade or partitioning functions for living rooms.
  • the blind can be freely deployed as needed and in the storage position, it occupies a very small volume because it has articulation properties which allow very flat folding of the fabric sheet.
  • the blind offers a smooth surface and the materials used to make it allow the color harmony and the appearance of the upholstery fabrics traditionally used to decorate rooms to be respected.
  • the folding articulated fabric without permanent fold, made continuously by weaving warp and weft threads of any material such as textile fibers, is characterized in that in its structure, it has at least one longitudinal zone of weakness which constitutes a privileged axis of folding.
  • the blind made with the articulated fabric of the present invention is characterized in that it is in the form of a panel with a single structure composed of rigid panels articulated together by preferred folding zones.
  • the present invention relates to a folding articulated fabric, without permanent fold, as well as a blind made with said articulated fabric. It will find its application in particular in the weaving industry of warp threads and weft threads formed of any materials such as textile fibers or metallic threads.
  • the articulation of the fabric of the present invention allows it to be folded with minimum effort.
  • the fabric of the present invention provides low folding resistance.
  • the fabric in its structure has at least one longitudinal zone of weakness which constitutes a preferred axis of folding. It should however be emphasized that the structure of the fabric of the present invention remains homogeneous, however.
  • the longitudinal zone of weakness results in greater flexibility of the fabric at this level and therefore when an external folding constraint is imposed on the fabric, the latter folds at this level.
  • the location of the fold is particularly interesting because. it allows storage of the fabric in a reduced volume without having to carry out a recovery operation to perform pleating as was traditionally performed.
  • the zone of weakness is produced in the very structure of the fabric and consequently the fold produced at this level is not permanent, which offers the possibility, after deployment of the fabric, of obtaining a smooth and smooth surface that is not wrinkled.
  • the fold made in the articulated fabric of the present invention has no meaning and therefore it is possible to fold the piece of fabric with an indifferent direction of folding.
  • the articulated fabric of the present invention has areas of weakness which are directed along the axes of introduction of the warp or weft threads.
  • the preferred folding axes are directed in the longitudinal or transverse direction of the fabric strip.
  • the roll 1 of fabric which is formed from the strip obtained in weaving has preferred folding axes 2 directed along the warp of fabric 1.
  • the deployed fabric offers perfect continuity, however, when the fabric band is compressed along its width, a series of localized folds is created at the level of the zones of weakness 2 which in a way constitute hinges.
  • FIG. 2 schematically represents the cross-sectional views of the piece of fabric 1 according to different folding modes.
  • FIG. 2a represents the articulated tissues 1 perfectly deployed. It offers a homogeneous and unique structure perfectly smooth.
  • the sections of tissue which do not constitute the joints be semi-rigid in order to decide in terms of rigidity with the zones of weakness.
  • Figure 3 shows schematically the structure of a fabric composed of son 3 warp and son 4 weft.
  • a simple structure has been envisaged to facilitate the understanding, however, it is obvious that complex armor could be adopted as well.
  • the creation of a preferred folding axis is obtained by a local modification of the weave of the fabric along the chain axis of the latter.
  • the preferred longitudinal axis of folding 2 is produced along the warp 3 of the fabric by local suppression of laying a warp yarn.
  • this local deletion is shown diagrammatically by the presence of a dotted line.
  • FIG. 4 Another embodiment, illustrated in FIG. 4, consists in adding longitudinal elements to the fabric 1 which will give the fabric a certain rigidity. Under these conditions, the intermediate zones 6 situated between the rigid or semi-rigid elements 5 constitute zones of longitudinal weakness which will form privileged folding axes.
  • stiffening elements 5 can also be replaced by surface treatments or primers which give the fabric rigidity.
  • the production of blinds with articulated fabric is particularly advantageous since, unlike previous techniques, the blind can be manufactured continuously. Indeed, the formation of the folds is directly carried out on a loom and only the cutting to size must be carried out a posteriori.
  • the blind is in the form of a fabric panel with a single structure.
  • the blind is made up of rigid panels, the rigidity of the panels depends on the nature of the wires used mainly in the warp to give the panels some hold.
  • the blind In the deployed position, the blind has a smooth and smooth surface, as shown in FIG. 2a and it can be folded up easily under reduced volume as illustrated in FIGS. 2d or 2e.
  • the blind can be entirely made of textile material, it can fully respect the harmony of the room in which it is located by matching with the wall furnishing fabric used to coat the walls of the room .
