[0001] The present invention concerns improved artificial hair.
[0002] It is known that artificial hair usually does not look like, neither feels like real
hair, such that it does not give a natural impression and it is often obvious that
someone is wearing a wig made of such artificial hair.
[0003] The present invention aims to remedy the above-mentioned and other disadvantages
by providing improved artificial hair which looks and also feels like real hair.
[0004] To this end, the present invention concerns improved artificial hair which mainly
consists of a synthetic support provided with a coating on the basis of cross-linkable
aliphatic polyurethane.
[0005] By cross-linkable is to be understood that the aliphatic polyurethane offers the
possibility to form cross links within the scope of an appropriate treatment.
[0006] Thanks to the coating, the color will look more natural as far as appearance, reflection
and sheen are concerned, just as with healthy natural hair, as opposed to non-coated
dry artificial hair.
[0007] Apart from the advantage of the resemblance to real hair, another advantage of the
improved artificial hair is that the coating does not wear by washing or combing the
hair and that it is also resistant to chemicals, as a result of which the artificial
hair will retain a natural look for a long time.
[0008] The present invention also aims to provide a method for manufacturing improved artificial
hair as described above, whereby a synthetic support is provided at least once with
a liquid coating on the basis of cross-linkable aliphatic polyurethane.
[0009] In order to better explain the characteristics of the invention, the following preferred
embodiment of improved artificial hair according to the invention is described as
an example only without being limitative in any way, with reference to the accompanying
drawings, in which:
figure 1 is a longitudinal section of an improved artificial hair according to the
invention;
figure 2 represents a cross section according to line II-II in figure 1 to a larger
scale;
figures 3 and 4 represent variants of an improved artificial hair according to figure
2.
[0010] The improved artificial hair 1 according to the invention mainly consists of a synthetic
support 2 with a circular cross section which is provided with a coating 3.
[0011] The above-mentioned synthetic support 2 consists for example of a polyester such
as polyethylene, or preferably of polyethylene terephtalate or what is called PETP.
[0012] The above-mentioned coating 3 according to the invention is made on the basis of
cross-linkable aliphatic polyurethane.
[0013] According to the invention, it is also possible to provide the above-mentioned coating
3, while being applied, with one or several additives in the form of thinners, distributors,
drying time accelerators, means determining the hardness, means to influence the reflection,
or the like.
[0014] The thickness of the improved artificial hair 1 is situated between one tenth and
four hundredths of a millimeter.
[0015] Figure 3 represents a variant of an improved artificial hair 1 according to the invention,
whereby the cross section has an oval shape.
[0016] Figure 4 represents yet another embodiment of an improved artificial hair according
to the invention whereby the cross section has what is called a "double round glass
shape".
[0017] It is clear that the cross section of an improved artificial hair 1 according to
the invention is not limited to the shapes represented in the figures.
[0018] The present invention also concerns a method for manufacturing improved artificial
hair 1 according to the invention, whereby a synthetic support 2 is provided at least
once and preferably several times with a liquid coating on the basis of cross-linkable
aliphatic polyurethane.
[0019] The coating is carried out by pulling the synthetic support through a bath of the
coating material.
[0020] The coating is done in a mechanical manner, by means of specialized equipment, whereby
a single thread is pulled through the coating machine according to what is called
the "single thread coating" process.
[0021] After the coating, a drying time between ten seconds and ten minutes is preferably
observed, whereby the improved artificial hair 1 according to the invention is exposed
to a temperature between fifty and two hundred degrees Celsius. The hair 1 will subsequently
cure further for 24 hours.
[0022] The present invention is by no means limited to the embodiment given as an example
and represented in the accompanying drawings; on the contrary, such an improved artificial
hair according to the invention can be made in all sorts of shapes and dimensions
while still remaining within the scope of the invention.
