DETAILED DESCRIPTION OF THE INVENTION

[0020] The present invention refers to a process to manufacture a weighted material for sportswear that allows to increase the force, resistance and muscle development in sportsmen and athletes during their training. The material obtained by the process described here is useful to be incorporated de clothing pieces such as t-shirts, shorts, leggings, ankle supports, ankle braces, wristbands, etc. Said weighted material has various advantages to the user, because it is thin, flexible, it adapts to the user's body shape, it can be washed after its use, and is not necessary to insert or remove the weights from the sportswear.

[0021] The main steps of the process described in the present invention includes: [0022] i) use a mold system at a temperature between 20 and 30 C.; [0023] ii) add between 1-99% in weight of steel spheres to the mold system; [0024] iii) add between 1-99% in weight of tungsten spheres to the mold system; [0025] iv) add in cold between 0.5-1.0 g/cm.sup.3 of an elastomer material to fix the steel and tungsten spheres; [0026] v) remove from mold after 6 to 12 hours; [0027] vi) add textile material for both sides to create a laminated with the same elastomer; and [0028] vi) add to the fabric of the sportswear through a seam, to elaborate diverse kinds of sportswear.

[0029] In addition, a weighted material for sports clothes is described, which is manufactured by the method previously described, wherein such material is composed by:

[0030] meal spheres (1);

[0031] elastomers (2); and

[0032] textile material (3).

[0033] The heavy and flexible material described in the present invention, includes metallic spheres from 1 to 3 mm of diameter, that can be conformed mainly by microspheres of metals such steel and tungsten. These two metals are used in order to mix their characteristics: tungsten is one of the more dense existing materials (18 g/cm.sup.3) as compared to steel, that has a high density (approx. 8 g/cm.sup.3), but lower compared to tungsten. When these two materials are mixed in different proportions and added to an elastomer and a mold system, it results in a material for sportswear of different densities and weights, because at the moment that the sportswear is elaborated, is possible to obtain clothes with the same dimension and size, but with different weights between them. This is an advantage to the final user, because at the moment of physical activity, it allows to use a specific sportswear with higher of lower weight, depending on the final physical goal of the user. Besides, such sportswear that contains the weighted material described in the present invention has more advantages, because it adapts to the user's body shape, it can be washed after its use, and does not require to insert or remove the weights from the sportswear.

[0034] In order to obtain a thin, flexible and heavy product, the metal spheres are mixed with some kind of elastomer that helps to fix the spheres and allow them to stay as a thin and flexible layer that can adapt to any form of the human body.

[0035] The metallic spheres (1) may have a density between 8-18 g/cm.sup.3, and the material can be selected from steel, tungsten or mixtures of them. The weighted material can include between 1-99% in weight of spheres from 1 to 3 mm of diameter composed by steel, and between 1-99% in weight of spheres from 1 to 3 mm of diameter composed by tungsten.

[0036] The elastomers (2) of weighted material for sportswear, can be selected from latex, rubber, silicone, or mixtures of them.

[0037] The textile material (3) of the weighted material for sportswear, can be selected from elastane (Spandex or Lycra), neoprene, cotton, polyester, or mixtures of them.

[0038] The weighted material is useful to elaborate a flexible and thin sportswear, with a thickness between 1 to 3 mm, and with a weight between 0.5 to 3.0 kilograms, and can include different products: [0039] Training leggings: when made with the weighted material described in the present invention, it allows to reach a weight between 0.5 and 3.0 kilograms and with this more calories in less time are burned when used, besides to tone up legs and gluteus. The kinds of sportswear includes Leggings, shorts and sweatshirts. [0040] Compression t-shirts: when made with the weighted material described in the present invention, it allows to reach a weight between 0.5 and 3.0 kilograms and with this more calories in less time are burned when used, besides to tone up arms, trunk and back. The kinds of sportswear includes sleeveless, short sleeve, long sleeve and t-shirts. [0041] Training belt: allows to replace wristbands and ankle braces that are currently in the market that are made from sand or metals, with the difference that the clothing pieces described in the present invention are more comfortable, they adapt to the user's body shape, they are flexible and thin, especially useful for the practice of diverse sports. The kinds of sportswear includes belts that can be used either as wristbands or ankle braces.

EXAMPLES

Example 1: Elaboration Process to Obtain a Weighted Material for Sportswear

[0042] With the aim to obtain a weighted material for sportswear, in tables No 1 and No 2 are resumed the assays performed, in which mold systems were used at a temperature between 20 and 30 C. After this, 1-99% in weight of steel spheres and 1-99% in weight of tungsten spheres were added to the mold system, and between 0.50-1.0 g/cm.sup.3 of the elastomeric component selected from elastane (Spandex or lycra), polyester or neoprene were added to the mold to fix de steel and tungsten spheres. This step was performed in cold. Table No 1 shows the assays realized using an amount of elastomer of 0.50 g/cm.sup.3 and table No 2 summarizes the assays realized an amount of elastomer of 1 g/cm.sup.3. After 6 to 12 hours, the mold was removed and the textile material was added for both sides to create a laminated with the same elastomer (FIG. 2). Finally, the elaborated material was added to the fabric of the sportswear, through a seam.
