Definitions

  • the present invention relates to a method of manufacturing filling or filling materials for wadded articles, based on fibrous material, in the form of elements of defined length, of small thickness compared to its length, comprising central wires relatively dense and rigid compared to all of the materials, said yarns being superimposed at equal distances on at least one of the faces of a fibrous sheet formed in a known manner and glued with the fibrous sheet, said fibrous sheet being divided into strips of on each side of each wire and finally, said strips being cut into elements of determined length, the fibers of which are oriented substantially transversely with respect to the wires and entangled with one another so as to form a homogeneous veil disposed on both sides 'other son substantially in the same plane.
  • Quilted or quilted articles have been known for a long time; they essentially consist of an external envelope, generally based on fabric or knitting which traps an internal layer constituted by feathers and / or various natural or chemical fibers in the form of sheets.
  • the filling materials allow obtaining a bulky structure, of a low weight, having a high insulating power, a satisfactory air permeability, as well as an excellent elasticity allowing the together to regain its bulk when the article is subjected to successive loads and discharges.
  • quilted products were made in the past from natural materials such as cotton, wool, kapok, and feathers.
  • natural materials such as cotton, wool, kapok, and feathers.
  • chemical materials such as in particular polyester fibers or the like.
  • packing plies directly from cables of chemical son by spreading the filaments constituting these cables and treatment in order to give them bulk and cohesion.
  • German patent application No. 1,111,140 it is also proposed to produce a thread of the above type by bonding threads on fibrous webs and tearing the fibers between two threads after bonding. This process, like the previous one, leaves parasitic fibers which are detrimental to subsequent use.
  • the filling material thus obtained imitating the natural feather can schematically be considered to consist of a flexible textile filiform rod, on either side of which are distributed and to which adhere textile fibers forming barbs.
  • connection of the spaced wires with the sheet is obtained under the combined action of heat and pressure, for example by passing between two heating cylinders.
  • These eyelets can have any shape, oval or round; however, it is important that their diameter is preferably smaller than the space separating two wires.
  • These eyelets are generally mounted on heddles, themselves held by a frame as they appear to hold the warp threads on a loom.
  • the rod-forming wire consists of the assembly of two wires having different bonding points, for example one being based on an interpolyamide, the bonding point of which is close to 120 to 140 ° C, and the other based on polyamide 6-6.
  • the wire of the rod can possibly be crimped or wavy.
  • the fibrous material linked to the central core constituted by the above-mentioned yarn is advantageously constituted by chemical fibers, such as polyester fibers, natural or artificial fibers, used alone or in the form of mixtures, of the same title or of title different, same section or different sections, same cut or different cut.
  • chemical fibers such as polyester fibers, natural or artificial fibers, used alone or in the form of mixtures, of the same title or of title different, same section or different sections, same cut or different cut.
  • the padding materials obtained by the process which is the subject of the present application can be of the same dimension or of different dimensions. This is how they can be of different length. They can also be of different widths; this is obtained by not spacing the wires regularly or by spacing them regularly but at spaces of different sizes. This gives a varied padding material, the mixture of products of different sizes can only provide more comfort.
  • a light brushing can be carried out to ruffle the fibers and take away the unwanted superfluous fibers which are deposited on a cleaning roller of the known type in spinning.
  • the new packing material obtained by implementing the method of the invention, is in the form of an element of defined length, of small thickness with respect to its length, consisting essentially of a central donkey 1 which is threadlike, relatively dense and rigid with respect to the whole of the material, to which are attached fibers 2 oriented substantially transversely to this core 1, said fibers being entangled with to each other and forming a homogeneous veil. These fibers 2 are arranged on either side of the core 1.
  • a fibrous sheet 4 is produced in known manner, which is packaged in the form of a roll 3, for example by means a carding machine, a pneumatic device.
  • a plurality of spaced heat-bonding wires 6, superimposed for example from individual coils 5, are superimposed on this sheet, coming from the roll 3.
  • the wires 6 are regularly spaced on said sheet 4.
  • heating rollers 7-8 By passing between heating rollers 7-8 , the connection is caused to the surface of the ply 4. This connection is obtained thanks to the heating rollers 7-8.
  • these rollers exert a pressure which promotes the connection of the two constituents.
  • each wire is passed through eyelets 9 thus causing the tearing of the sheet and the formation of bands 10, the fibers pass into the eyelet through which the wire 6 passes to which they adhere most securely. Then said strips 10 are cut, for example by means of knives 11 so as to obtain elements 12 of determined length which are recovered in a storage member 13.
  • the filling material obtained by the process which is the subject of this application is used on the same materials as those used for natural feathers.
  • the padding material obtained is used for padding, wadding articles of bedding (pillows, bolsters, eiderdowns, bedspreads, bedspreads, etc.), clothing, furnishings, in the manufacture of clothing , for decoration, headgear and for thermal and sound insulation.
  • the calendering at 180 ° C. of the fibrous web / web of yarns causes the polyethylene to melt and the fibers of the web to adhere to the yarns.
  • the strips 10 are formed by passing each son through a round eyelet 9 with a diameter of 15 mm, the fibers passing through the eyelet through which the wire passes with which they adhere best.
  • the running speed of the assembly is 6 meters / minute; the strips 10 thus produced have an average width of 15 to 20 mm.
  • the sheet thus formed is wound in the form of a roll 3.
  • the bonding point is between 120 and 140 ° C and a 6-6 polyamide wire.
  • These two wires are assembled at 60 turns / meter and the total titer of the assembled wire is 600 dtex.
  • the wires 6 are spaced 15 mm from each other.
  • the bonding of the wires 6 is caused on the web 4.
  • the speed of movement of the set is 5 m / minute.
  • the assembly thus formed is separated by passing the wires 6 through the eyelets 9. In this way, strips 10 having a width of 15 mm are produced and having in their central part a wire continuous 6. These strips are then cut by means of knives 11 into elements 12 of defined length.
  • the article obtained therefore comprises a relatively dense and rigid filiform central core 1 to which fibers 2 are linked which form a homogeneous veil and which are oriented substantially relative to this transverse core giving the appearance of a natural down.
  • Such an article is particularly suitable for filling materials to replace natural feathers. It makes it possible to communicate to the articles produced properties comparable to previous articles made from natural down and feathers, in particular with regard to the volume and the power of insulation. It is economical to make, easy to store. In addition, it has the advantage of being able to be used as it is on conventional equipment making it possible to produce filling articles using natural feathers.
  • this article can also be used in the form of a sheet after transformation on suitable equipment and in particular pneumatic equipment.
