Definitions

  • the present invention has as subject a hair extension, of the type used in particular for thickening hair, substantially shaped like a foil or weft, known under the term of weft extension o weft hair extension.
  • a lock of hair constituted by a plurality of human or artificial hair is meant, apt to be handled as single lengthening unit and to be applied on receiving hair thanks to a connecting element.
  • the weft hair extension has a linear connecting element therefrom natural or artificial hair branches perpendicularly, arranged in a planar configuration with a uniform distribution.
  • Another aspect contributing to increase the appreciation of this type of treatments is the speed in performing it.
  • the known systems then provide a step wherein the hair extensions are connected to the user's hair.
  • the hair extensions can be substantially sewn, tied up or knotted to the user's hair.
  • Means for implementing the connection between hair extensions and hair is also known, providing the use of outer elements such as clips, combs, tweezers and the like. With these elements, hair extensions with great sizes can be associated to the user's receiving hair.
  • US patent No. 3,280,826 (Jenkins ) describes a multi-layered weft hair extension, obtained by folding on itself a long weft of hair connected to a thread-like element; this extension is then fastened to hair by means of clips.
  • Other extensions applicable by means of fastening mechanical means or stitcher are known from US patents No. 4,830,029 (Bird ); No. 5,121,761 (Meister ) and No. 5,881,737 (Nelson ).
  • US patent No. 6,135,122 (Campbell et al. ) describes a weft hair extension with a single layer, wherein the hair are kept in their position by a closely woven band provided with an adhesive layer; other extensions of this type are known from US patent applications No. 2001/0035192 (Townsend ); No. 2006/0169296 (Gill et al. ); No. 2009/0032041 (Ott ); No. 2009/0120451 (Kenna ); and No. 2013/0298925 (Gold ); and from International patent application No. WO 2011/036654 (Gold ).
  • EP 2,614,736 (Lee ) describes a weft hair extension wherein hair is kept at one end thereof by a strip of plastic material (polyurethane), provided with holes for the passage of receiving hair which is used then for locking the extension thanks to the use of small fastening rings which are squeezed by means of suitable tweezers.
  • French patent No. FR 2,968,520 (L'Oréal ) describes a weft hair extension with a first linear connecting element of thermoplastic type, used for connecting hair at one end thereof, and a second linear connecting element formed by an additional strip made of thermoplastic material, arranged parallelly to the first connecting element, but the application of this extension determines a thickening of the connecting area which can be noticed both by the carrying user and by third parties.
  • the technical problem underlying the present invention is to provide a weft hair extension to thicken hair and a relative manufacturing method allowing to obviate the drawbacks mentioned with reference to the known art.
  • the main advantage of the hair extension according to the present invention lies in the fact of allowing a quick application by using said tab-like elements as devices for anchoring the hair extension to host hair, without increasing the extension thickness.
  • thermoplastic features of the second linear connecting element Furthermore, a permanent application is possible by using the thermoplastic features of the second linear connecting element.
  • the method for manufacturing the weft hair extension according to the present invention comprises the steps of:
  • figure 1 illustrates a first step of the method for manufacturing, according to the present invention, a weft hair extension wherein a flat foil 1 of straight hair is arranged on a plane, for example made of steel.
  • the hairs are arranged in an orderly manner, parallel therebetween, with the respective proximal ends thereof, that is those cut near the scalp, arranged to form an almost straight line.
  • the hairs are selected to that they substantially have the same length, and in case the respective distal ends will be evened with a rectilinear cut.
  • Hair can be of any type, preferably it is natural. I form a foil with almost uniform thickness, in the order of tenths of millimetre.
  • a first strip 3 made of thermoplastic material is placed, so as to soften temporarily by means of applying a predetermined temperature, for example 200°, or in case of ultrasounds. This softening allows to penetrate the hair strip, by applying a certain pressure.
  • the strip 3 is made of a resin or thermoplastic rubber, possibly a refoldable material, soft to the touch.
  • the strip 3 is arranged perpendicularly to the single hair of the foil 1.
  • the strip 3 is pressed by a heated press 4 which softens the strip 3 by causing the penetration of the hair distal ends of the foil 1 in the thickness of the strip, penetration which takes place at a first face of said strip.
  • the thickness of the thermoplastic strip could be about 1 mm or even smaller.
  • a second strip 5 made of thermoplastic material is arranged at a certain distance from said first strip 3, substantially parallel thereto.
  • the distance is so as to allow the passage between the strips 3, 5 of connecting means of the extension, for example thin locks of host hair which could be used to apply said extension, for example comprised between 2 and 5 mm.
  • tab-like flexible elements 6 are provided, in the form of small strips with length so that they can extend transversally, and then preferably perpendicularly, to the thermoplastic strips 3, 5, by covering at least partially the height thereof of both of them.
  • the tab-like elements 6 are then so arranged like a bridge between said thermoplastic strips 3, 5, arranged each one at the same distance from the adjacent tab-like elements.
  • the tab-like elements 6 are made of porous material and with reduced thickness, so that they, or portions thereof, can be embedded, i.e. embeddable, with pressure within the strips made of thermoplastic material 3, 5.
  • the material thereof they can be formed could be gauze or organza, in particular then a tissue formed by a plain weave, for example cotton or other natural textile fibre, nylon, polyester and so on. It is to be meant that the selected material should be flexible.
  • the tab-like elements 6, are arranged as described previously. It is to be noted that, in this step, the foil 1 and the respective linear connecting element 3 have been turned, so as to expose the face of strip 3 opposite to that therethrough the hair of the foil 1 have been previously penetrated.
  • the tab-like elements are penetrated in the respective thicknesses of the two strips 3, 5 made of thermoplastic material by means of hot pressing, for example by means of the previously mentioned press 4, in similar way to what described previously for the distal end 2 of the foil 1.
  • the tab-like elements 6 will constitute flexible connecting means between the strips 3, 5, and the second strip will constitute a second linear connecting element 5.
  • Such weft hair extension 10 then will include a flat foil 1 of hair aligned therebetween, kept together by a first linear connecting element 3 which is formed by a strip made of thermoplastic material wherein the proximal end 2 of hair of said flat foil 1 is embedded. It further comprises a second linear connecting element 5 formed by an additional strip made of thermoplastic material arranged parallelly to said first linear connecting element 3 at a distance therefrom.
  • the two connecting elements 3, 5 are hinged therebetween thanks to transversal connecting means which is constituted by one or more tab-like flexible elements 6, preferably at least two.
  • tissue strips described previously: they could have a shape like a double T, so as to implement a greater grasp with the strips. It is further meant that the open-worked tissue is only one of the possible variants applicable to such hinge elements.
  • the two strips of suitable material have the capability of keeping a fixed position once arranged between two locks of host hair covering them completely, by implementing a stable and poorly perceivable to the touch or by shaking her head, this because they adhere to the host locks by adapting to the shape and motions thereof.
