EMBODIMENTS OF THE INVENTION

[0037] Referring to FIGS. 1A and 1B, a garment 100 comprises a fabric 10 formed by a first yarn 1 and a second yarn 2.

[0038] The first yarn 1 comprises granules or microcrystals 1a of material adapted to reflect, and/or emit and/or absorb infrared radiation. Typically, these materials comprise bioceramic materials and comprise at least one element selected among titanium (preferably titanium dioxide), magnesium, zinc, silicon, aluminum. However, other materials adapted to carry out such a function are known in the art and may be used with the present invention.

[0039] A preferred embodiment provides that 1 kg of first yarn contains an amount of magnesium between 1 mg and 5 mg, an amount of zinc between 6 mg and 10 mg, an amount of aluminum between 80 mg and 114 mg, an amount of silicon between 157 mg and 257 mg, and an amount of titanium between 1860 mg and 2260 mg. More preferably, the first yarn comprises an amount of bioceramic material whose composition is measured out so that in 1 kg of first yarn 1 there is an amount of magnesium substantially equal to 3 mg, an amount of zinc substantially equal to 8 mg, an amount of aluminum substantially equal to 110 mg, an amount of silicon substantially equal to 207 mg and an amount of titanium substantially equal to 2060 mg.

[0040] Typically, the first yarn 1 is made of polyamide or polyester. Preferably, the dimensions of such particles, granules or microcrystals 1a are between 0.5 m and 1 m. Moreover, such granules or microcrystals 1a are generally in the first yarn in a weight percent between 4% and 5%.

[0041] Microcrystals (or granules or particles) have properties of emitting radiations in the infrared region in a wavelength range from 2 m to 20 m (FIR).

[0042] The second yarn 2 comprises microcapsules 2a and is typically made of polyamide. Preferably, the second yarn has thread count of 44/34 dtex, although yarns of different sizes may be used. Generally, the second yarn is weaved with another elastomeric yarn, preferably having thread count of 44/1 dtex, so as to provide the fabric with the required elasticity.

[0043] A cosmetic compound, typically including at least one of caffeine, Aloe vera, vitamin A, vitamin E, is contained inside the microcapsules 2a.

[0044] A preferred embodiment may provide that the cosmetic compound contained inside the microcapsules is a composition comprising castor oil, zeolite, aloe barbadensis leaf juice, oleic acid, polyhydroxystearic acid, silica, retinyl palmitate, tocopheryl acetate, tocopherol, sodium benzoate, potassium sorbate, caffeine. An example of a cosmetic product is shown in the table below.

TABLE-US-00001 INCI NAME % W/W CAS NUMBER RICINUS COMMUNIS (CASTOR) SEED 40.100 8001-79-4 OIL ZEOLITE 40.100 1318-02-1 ALOE BARBADENSIS LEAF JUICE 4.250 85507-69-3 OLEIC ACID 4.250 112-80-1 POLYHYDROXYSTEARIC ACID 4.250 27924-99-8 SILICA 4.250 7631-86-9 RETINYL PALMITATE 0.800 79-81-2 TOCOPHERYL ACETATE 0.400 7695-91-2 TOCOPHEROL 0.400 10191-41-0 SODIUM BENZOATE 0.400 532-32-1 POTASSIUM SORBATE 0.400 24634-61-5 CAFFEINE 0.400 58-08-2

[0045] Referring to FIGS. 2A, 2B, at least part of the granules 1a of material adapted to reflect and/or emit and/or absorb infrared radiation is inserted inside the first yarn 1. Similarly, as shown in FIGS. 3A and 3B, at least part of the microcapsules 2a are arranged inside the second yarn 2.

[0046] A possible solution to obtain the first yarn is the following one. Firstly, granules (masterbatch) are prepared, filled with granules 1a of material adapted to reflect and/or emit and/or absorb infrared radiation. Preferably, the masterbatch is polyamide-based, or in any case based on the polymer the first yarn 1 is mainly composed of.

[0047] Typically, the masterbatch is formed by adding to a molten polymer (e.g., polyamide) granules 1a of material adapted to reflect and/or emit and/or absorb infrared radiation, and subsequently cooling the material thus obtained.

[0048] Such granules are mixed to a polymeric material (typically polyamide, as above mentioned), and the resulting compound is melted and extruded for the spinning.

[0049] Therefore, the material adapted to reflect and/or emit and/or absorb infrared radiation can be substantially uniformly dispersed inside the first yarn 1.

[0050] Similarly, a possible solution to obtain the second yarn is the following one. Firstly, granules (masterbatch) filled with microcapsules, are prepared. Preferably, the masterbatch is polyamide-based, or in any case based on the polymer the second yarn 2 is mainly composed of.

[0051] Typically, the masterbatch is formed by adding the microcapsules to a molten polymer (e.g., polyamide), and subsequently cooling the material thus obtained.

[0052] Such granules are mixed to a polymeric material (typically polyamide, as above mentioned), and the resulting compound is melted and extruded for the spinning. Therefore the microcapsules 2a can be substantially uniformly dispersed inside the second yarn 2.

[0053] Preferably, the microcapsules 2a are designed to release their own content (or anyway part of their own content) only when a given threshold temperature is exceeded, threshold temperature which, as said, is preferably equal to 35 C. (human body temperature).

[0054] In the embodiment shown in FIG. 3B, the microcapsules have holes 21 covered by membranes 22 which, as the threshold temperature (e.g., 35 C.) is exceeded, allow the cosmetic compound (symbolically denoted by drops coming out of the holes 21 of the microcapsule 2a) to pass through the holes 21 of the microcapsules. As above mentioned, the membranes 22 preferably change their permeability depending on the temperature and, as the threshold temperature is exceeded, allow the cosmetic compound to pass through the holes 21. Conversely, when the temperature of the microcapsule is lower than the threshold temperature, the membranes 22 hold back the cosmetic compound inside the microcapsules 2a themselves. The shell of the capsules is typically composed of silicates.

[0055] Preferably, as the threshold temperature is exceeded, the membranes 22 allow a slow release of the contents so that some time is needed to empty the microcapsules 2a. Typically, the microcapsules 22 are in the second yarn 2 in a weight percent between 0.5 and 1%.

[0056] The two yarns 1, 2 are preferably weaved so that the first yarn is mainly arranged on one side of the garment, while the second yarn 2 is mainly arranged on the opposite side. In particular, the fabric constituting the garment is such that the second yarn 2 is preferably arranged towards and in contact with the skin of a user wearing the garment itself, whereas the first yarn 1 is spaced from the skin of the user wearing the garment itself, precisely for the interposition of the second yarn 2, and is outwardly oriented.

[0057] Preferably, the inner side of the garment 100, when in use and facing the user, has a negligible amount of first yarn 1 with respect to the amount of the second yarn 2. More preferably, on the inner side of the garment 100, when in use and facing the user, there is only the second yarn.

[0058] Preferably, the outer side of the garment 100, when in use and facing the user, has a negligible amount of second yarn 2 with respect to the amount of the first yarn 1. More preferably, on the outer side of the garment 100, when in use and facing outward, there is only the first yarn 1.

[0059] As above mentioned, according to a preferred embodiment such condition is obtained, for example, by making a fabric according to the processing technique known as plating, schematically shown in FIG. 4.

[0060] It should be noted, therefore, that the magnification of FIG. 1B is only a schematic representation that, although allowing the two yarns 1, 2 to be displayed, does not necessarily represent the preferred embodiment.

[0061] In use, granules or microcrystals 1a reflect or absorb and emit infrared rays emitted by the body in the form of heat. The infrared rays penetrate the cutaneous and subcutaneous layers, thereby improving the microcirculation and drainage of the excess liquids.

[0062] The body heat and the action of the granules or microcrystals 1a activate the special membranes 22 covering the holes 21 that are on the microcapsules 2a, thereby allowing the components (active principles) contained therein to pass on the skin and slowly spread thereon, thus improving skin hydration and elasticity and counteracting cellulite blemishes.

[0063] Instrumental clinical tests proved that the continuous use of leggings made of a fabric according to the present invention leads on average to a significant reduction of waist, hips and thighs circumference, as well as an increase of skin elasticity and hydration.

[0064] In addition, a visible improvement in the appearance of the skin was found and a thermographic analysis revealed a reduction in cellulite.
