The yarn 10 preferably has a yarn count of 16 tex to 55 tex.

[0043] A yarn according to another preferred embodiment of the invention is illustrated in Figure 2, and shown generally at reference numeral 20. As shown in Figure 2, the yarn 20 comprises a core strand 22, and a first cover fiber 24, a second cover fiber 25 and a third cover fiber 26 wrapped around the core strand 22. The first and second cover fibers 24, 25 are wrapped around the core 22 in a helical configuration, with the first cover fiber 24 in a Z-twist and the second cover fiber 25 in an S-twist, as shown in Figure 2. The third cover fiber extends around the core 22 in an S-twist, intermediate the first and second cover strands 24, 25, as shown in Figure 2. Alternatively, the covers 24, 25, 26 can be arranged in different twist arrangements and geometries. For example, the first cover 24, second cover 25 and third cover 26 can be wrapped around the core 22 in an S-twist. The yarn 20 preferably has a yarn count of 16 tex to 55 tex.

[0044] The core strand 22 is comprised of elastane (also known as spandex and lycra). The first and second cover fibers 24, 25 can be comprised of polyester, polypropylene, polyamide, wool, cotton, viscose, aramid, flame retardant viscose fiber (known as "FR viscose"), or modacrylic. Preferably, the first cover fiber 24 comprises polyester, and the second cover 25 comprises polypropylene.

[0045] In another preferred embodiment, the first cover fiber 24 comprises polyester and the second cover fiber 25 comprises polyamide. In another preferred embodiment, the first cover fiber 24 comprises polypropylene, and the second cover fiber 25 comprises polyamide. In another preferred embodiment, the first cover fiber 24 comprises wool, and the second cover fiber 25 comprises polypropylene. In another preferred embodiment, the first cover fiber 24 comprises polyester, and the second cover fiber 25 comprises wool. In another preferred embodiment, the first cover fiber 24 comprises polyamide, and the second cover fiber 25 comprises wool. In another preferred embodiment, the first cover fiber 24 comprises wool, and the second cover fiber 25 comprises cotton. In another preferred embodiment, the first cover fiber 24 comprises viscose, and the second cover fiber 25 comprises cotton. In another preferred embodiment, the first cover fiber 24 comprises aramid, and the second cover fiber 25 comprises modacrylic. In another preferred embodiment, the first cover fiber 24 comprises FR viscose, and the second cover fiber 25 comprises aramid.

[0046] The third cover fiber 26 is comprised of silver, copper, ceramic fiber, or carbon fiber, or a combination thereof. For example, the third cover 26 can be comprised of silver and ceramic fiber. Preferably, the third cover 26 comprises a silver fiber.

[0047] According to an embodiment of the invention, a base layer garment can be made utilizing any of the above described yarns 10, 20 in a whole garment-rectilinear machine (known in Italian as "macchina rettilinea a capo completo"), such as the machine sold by Japanese manufacturer Shima Seiki under the name "MACH2S." The use of whole garment-rectilinear machines with yarns 10, 20 produce seamless garments.

[0048] Whole garment-rectilinear machines are typically used with specific types of textiles. The textiles commonly used with whole garment-rectilinear machines typically lead to garments not suitable to be used as base-layers (often because they are too thick or do not present the necessary technical features). However, the yarns 10, 20 of the present invention can be knitted by whole garment-rectilinear machines to produce totally seamless base-layer garments which due to their high level of elasticity show a significant change in their grams per inch ratio and become much thinner when worn on a person's body. The fibers of the yarn 10 or 20 can be twisted together on a distaff so as to make the yarn 10, 20 appear like one fiber ("ritorti insieme su rocca in un unico filato").

[0049] The combination of the yarn 10, 20 of the present invention and the whole garment-rectangular machine manufacturing process can produce garments, such as the long sleeve t-shirt 30 shown in Figure 3, with high performance in various ways, such as elasticity, breathability, thermo-regulatory properties, antimicrobial properties, and comfort. The garments are seamless and form fitting. The garments can adhere perfectly around the body of the wearer, providing complete freedom of movement for the wearer. In addition, such adhesion facilitates the expulsion of perspiration of the wearer.

[0050] The garments have the feel of a second-skin to the wearer. Garments made by the process and yarns 10, 20 of present invention can provide high antibacterial properties and regulate temperature.

[0051] There is no interruption of thread in the manufacturing process. The inserted yarn on distaff remains continuous in all phases of the process, allowing the thread and silver fiber (preferably comprised of 99% pure silver) in each garment to be produced without interruption. Alternatively, copper fiber can be used in place of silver. The continuity of the wire and the presence of silver or copper in the garment can confer to the garment high antibacterial capabilities that in turn increase significantly when the garment is heated by a natural source such as the body heat of the wearer.

[0052] The accumulation and temperature maintenance, the high level of elasticity of the yarn 10, 20 and the particular manufacturing process of the seamless and whole 3D garment, facilitates the expulsion of sweat and speeds up the drying of the garment, leaving continuously dry skin. The silver conductive characteristics also allow for the dissipation of electrostatic charges from the body.

[0053] Articles made with the machining process and yarns 10, 20 of the present invention can include knitted underwear; clothing for dogs, horses, rabbits, cats and other animals; interior linings for work gloves, base layer garments for wearing during athletic and medical activities; clothing for the treatment of hyperhidrosis; socks and thermo heated gloves; interior layers for technical clothing; interior layers for gloves and sock fabrics; blankets; pillowcases; and covers. There are many ranges of products obtainable according to different requirements, including the use of fireproof yarns for protective clothing.

[0054] A form fitting garment and method of making same are described above. Various changes can be made to the invention without departing from its scope. The above description of embodiments of the invention are provided for the purpose of illustration only and not limitation— the invention being defined by the claims and equivalents thereof.
