Description

(1) With the intention of better showing the characteristics of the invention, preferred embodiments of artificial hair according to the invention are described hereinafter by way of an example, without any limiting nature, with reference to the accompanying drawings, wherein:

(2) FIG. 1 schematically shows a top view of one artificial hair with a core of natural fibroin fiber according to the invention;

(3) FIG. 2 shows a cross-section according to line II-II of FIG. 1 perpendicular to the longitudinal direction of the artificial hair;

(4) FIG. 3 schematically shows a cross-section of an artificial hair with a mono-filament core of a high performance polymer according to the invention;

(5) FIG. 4 schematically shows a cross-section of a variant of FIG. 3 with a multi-filament core of a high performance polymer.

(6) FIG. 1 schematically shows a top view of one artificial hair 1 with a core of natural fibroin fiber, that demonstrates its constant diameter, in this case 65 m.

(7) FIG. 2 schematically shows an electron microscope image of a cross-section of the artificial hair 1 of FIG. 1, on which in this case ten constituent fibroin fiber filaments can be seen in the core, surrounded by a cross-linked matrix 3 in which recross-linked, hydrolysed and liquefied human hair 4 is present, and whereby the diameter of the artificial hair is 65 m in this case.

(8) FIG. 3 schematically shows a cross-section perpendicular to the lengthwise direction of one artificial hair 5 with a core 6 of a high performance polymer according to the invention, showing its hair fiber diameter of 80 m. The artificial hair 5 comprises a mono-filament core 6 with a diameter of 50 m, in which boron nitride particles 7 of three m are taken up. The core 6 is surrounded by a layer of epoxy-glue 8 that ensures the bonding between the core 6 and the surrounding mantle 9 of natural organic material that has a thickness of 15 m. The surrounding mantle 9 is finished with a finish layer 10 with a coam polymer that provides good gliding properties of the hair.

(9) FIG. 4 schematically shows a cross-section of a variant 11 of a single artificial hair of FIG. 3, whereby in this case the core of high performance polymer is a multi-filament core 12 comprising several filaments 13 of a high performance polymer, around which in this case a concentric mantle 9 of natural organic material is represented that is bound by means of an expoxy-glue 8 to the core 12, and is finished by means of a finish layer 10 with a coam polymer on the outside.

(10) The use of the artificial hair is very simple and as follows.

(11) The artificial hair can be used in hair extensions and as weft in long-haired wigs in order to change or improve hairstyle or to lengthen their hair.

(12) The use of the artificial hair is no different to natural human hair, because the artificial hair is resistant to the usual operations that are applied to human hair.

(13) For example, the artificial hair is resistant to and/or compliant with washing, hot showers, thermal waving or thermal curling, cutting and perming, colouring, bleaching, combing and treatment with hair-care products.

(14) The present invention is by no means limited to the embodiments described as an example and shown in the drawings, but an artificial hair according to the invention can be realised in all kinds of variants, without departing from the scope of the invention as defined in the claims.
