Description

IMPRESSIVE COMPRESSION CLOTHES OF MINERAL MATERIAL EMITTING IN FAR INFRARED

The invention relates to compression garments, and in particular compression garments including inorganic materials emitting radiation in far infrared.

Far infrared have wavelengths between 3 micrometers and 1 millimeter. Far-infrared radiation, particularly in a wavelength range of 4 micrometers to 14 micrometers, has good ability to pass through cutaneous tissues. Far Infrared is recognized for activating and warming body cells from the inside. Therefore, clothes have been developed to emit radiation in far infrared. Such clothing is used both as part of a sports activity or in the daily setting to improve the comfort or health of the user.

Some mineral materials (and some ceramics in particular) having the property of absorbing energy radiation to re-emit in a large proportion in the far-infrared, different types of clothing have been developed by combining a fibrous tissue with a resin including these materials.

US 2003/0236042 discloses methods of making a garment. The fabric in which the garment is made includes fibers.

According to a first method described, these fibers are formed by including powders of inorganic materials inside a resin, and then forming a filament from this mixture. The filament is then woven to make the fabric.

In practice, the presence of the powders inside the fibers greatly reduces their elasticity and their resistance to breakage. Therefore, such fibers have a high wear rate and a reduced service life. Such fibers are therefore unsuitable for clothes having to have high elasticity. Such fibers are even less suitable for clothing intended for sporting use because of the significant friction encountered which induces accelerated wear.

According to a second method described, a resin, a catalyst and mineral materials emitting in the far infrared are mixed in well-defined proportions to form a polymer mixture. The polymer mixture is then granulated. The granules are then melted and shaped to form a membrane by blowing or compression. The resulting membrane is then coated with an adhesive and then fixed to a usual fabric. The fabric is then cut according to different patterns. The patterns are then assembled in a manner known per se to form the garment. The garments thus obtained also have disadvantages. Their elasticity remains insufficient and the membrane is prone to premature wear, especially during sports. The manufacturing process is also relatively expensive. Such clothing also makes sweat evacuation more difficult.

The invention aims to solve one or more of these disadvantages.

The invention thus relates to a compression garment, characterized in that it comprises:

a composite material including a polymer matrix in which particles of a mineral material capable of emitting far-infrared radiation are embedded;

a fabric intended to surround a member of the user and having at least one coated part of said composite material.

In one embodiment of the invention, the composite material forms patterns spaced from each other. The patterns may be spaced from each other in all directions in the plane of the fabric by a distance of at least 1.5 mm and they may have an area less than 2 cm ² .

The garment of the invention may be a leggings whose section intended to surround the calf has a given perimeter defined in a standardized manner such as the calf circumference of the leggings, the leggings being secured to a tag comprising a corresponding standardized size indication. at a minimum perimeter of the user's calf circumference, the ratio between this minimum perimeter and said given perimeter being greater than or equal to 1.03.

The garment of the invention may also be a shorts whose section to surround the thigh has a given perimeter defined in a standardized manner such as the thigh of the thigh, the shorts being secured to a label comprising a corresponding standardized size indication at a minimum perimeter of the thigh of the user, the ratio between this minimum perimeter and said given perimeter being greater than or equal to 1, 01.

The garment of the invention may also be a T-shirt with a section intended to surround the chest has a given perimeter defined in a standardized manner such as the chest of the T-shirt, the T-shirt being secured to a label comprising a standardized size indication corresponding to a minimum perimeter of the user's chest circumference, the ratio between this minimum perimeter and said given perimeter being greater than or equal to 1, 01.

The mineral material used in the garment of the invention contains a ceramic powder capable of emitting far infrared radiation. Said powder may contain at least one oxide among the following oxides: Al ₂ O ₃ , Fe ₂ O ₃ , ΤΊΟ ₂ , Cr ₂ O ₃ , SiO ₂ , MgO, ZrO ₂ , MnOy, Co ₂ O ₃ , Y ₂ O ₃ . We will prefer a mineral material that has a peak of radiation at a wavelength of between 4 and 14 pm when excited by visible light and placed at 30 ° C.

The invention also relates to a method of manufacturing a compression garment, comprising the steps of:

- Coating a fabric with a composite material including a polymer matrix in which are embedded particles of a mineral material capable of emitting far-infrared radiation;

- transforming the fabric to form the compression garment, said transformation comprising the assembly of two edges of fabric.

attaching a label to the fabric, said label comprising a standardized size indication corresponding to a minimum perimeter of a limb of a user, the perimeter of a section defined in a standardized manner of the garment formed being less than minimum perimeter.

Other characteristics and advantages of the invention will emerge clearly from the description which is given hereinafter, by way of indication and in no way limitative, with reference to the appended drawings, in which:

- Figure 1 is a front view of a portion of a garment according to one embodiment of the invention;

FIG. 2 is an enlarged sectional view of the portion of FIG. 1;

- Figure 3 is a perspective view of a shorts according to a variant of the invention;

- Figure 4 is a perspective view of a leg according to another embodiment of the invention;

- Figure 5 is a perspective view of a T-shirt according to yet another variant of the invention.

For the purposes of the present invention, far-infrared radiation is infrared radiation whose wavelength is for example between 3 pm and 100 pm. Advantageously, it is infrared having a wavelength of between 4 and 15 pm, preferably between 4 and 14 pm.

The invention provides a compression garment comprising a composite material including a polymer matrix in which particles of a mineral material are embedded. This mineral material is capable of emitting and reflecting far infrared radiation. The garment includes a fabric for surrounding a limb of the user with a compression effect and having at least a coated portion of said composite material.

The invention combines the physiological effects of compression and far-infrared radiation with a garment having increased strength and durability. The compression garment may for example be a tights, a t-shirt, a shorts or a leggings. Such a compression garment can be used for sporting or other practice, for example for the practice of trail running in English language.

Figure 1 illustrates a front view of a portion of the surface of a garment according to the invention. The garment includes a fabric 2 for covering, wrapping and compressing a defined portion of the wearer's body. The fabric 2 can thus be intended to surround a member of the user, such as the arm, the neck, the torso, the thigh or the calf. The fabric 2 has at least a portion of its surface coated with a composite material 3. The composite material 3 includes a polymer matrix in which are embedded or incorporated particles of a mineral material capable of emitting far-infrared radiation.

In particular, the composite material 3 may comprise a matrix based on a breathable hydrophilic polymer. A hydrophilic polymer is said to be breathable if it is permeable to water vapor, but impervious to liquid water and, advantageously, if it has the property of being windproof. Such properties are particularly advantageous for a garment intended for sports. The matrix may be based on polytetrafluoroethylene (PTFE), polyurethane, polyester (PE), acrylic, polyvinyl chloride (PVC), polystyrene-butadiene copolymer (SBS), natural or artificial latex (polyisoprene) , or any other thermoplastic or thermosetting polymers.

Far Infrared Mineral Particles (the far-infrared term will hereinafter denote a material re-emitting a significant part of the radiation or energy received in the form of radiation having a wavelength of between 3 and 100 μm, preferably between 4 and 100 μm. and 14 μm) are distributed, preferably homogeneously, in the polymer matrix. More specifically, the mineral material may have a peak of radiation at a wavelength of between 4 and 14 pm when excited by visible light and placed at 30 ° C.

Far infrared radiation can increase the skin temperature and cause a sensation of heat by being absorbed by the skin (epidermis and / or dermis) by transforming the radiation into heat. Far Infrared also increases blood flow to the skin through the dilation of capillaries. Oxygenation is also improved. Far Infrared also activates the metabolism and reduces the sensation of pain and the risk of injury. Recovery after exercise is also facilitated.

The mineral material may for example be selected from natural materials such as jade, granite, serpentine or dolomite. The inorganic material may also be chosen from ceramics containing oxides among the following oxides: Al ₂ O ₃ , Fe ₂ O ₃ , TiO ₂ , Cr ₂ O ₃ , SiO ₂ , MgO, ZrO ₂ , MnOy, C02O3, Y2O3. Mixtures of many of these natural oxides or minerals may also be used.

The fabric 2 will advantageously be made of a material that is customary for compression garments, having a high elasticity. This material may for example comprise elastane, non-microfibre polyamide (for its aesthetic properties and transparency) microfiber polyamide (for its elasticity properties, comfort, softness and strength), cotton ( especially for sensitive skin and for its properties of limitation of sweating), natural gum (for its elastic properties and low ecological impact) or micro wool (for its opacity, its absorption capacity, its softness, its insulating properties and its low ecological impact). The type of fabric used can be very variable. For example, the fabric 2 may be selected from nonwoven fabrics, woven fabrics (warp and weft fabric), knitted fabrics (knits) and their assemblies. However, it is important that the fabric has good quality of elasticity and stretch.

A compression garment is intended to apply an elastic force around a body part of a user. The compression garment generates physiological effects on its user by the application of compression on the skin. Compression levels are defined in different official standards (for example in AFNOR standards in France or GZG standards in Germany). Compression promotes blood flow through the veins, lowers blood pressure and reduces leg pain or heavy leg sensation. Compression increases blood flow, reduces blood volume in the veins and reduces reflux to damaged veins. Moreover, the compression prevents the body tissues from containing too much water, promotes the drainage of harmful substances, reduces inflammation, promotes regeneration processes and improves the movement of tendons and joints.

The combination of a compression fabric and a far infrared mineral material makes it possible in practice to improve muscle tone. This combination improves the distribution of the user's mass. The posture of the user is thus rebalanced towards his center of gravity. Moreover, this combination makes it possible to combine and reinforce the beneficial effects described above. The advantages of the far infrared mineral material are indeed greater when this material is in pressure with a part of the body.

Another advantage that results is the improvement of the blood flow without a strong compression of the muscles. Indeed, too much compression causes an unpleasant feeling of the sportsman, even an embarrassment, in his movements. With this combination, one can thus obtain a good compromise with an improved blood circulation for a compression at least. This combination also results in improved resistance to effort. The athlete keeps a good maintenance of his limbs all along an endurance race, hence less fatigue.

This type of compression garment structure is particularly effective when the combination of the compression with a far infrared mineral material is localized in a part of the body solicited during the practice of a sport of endurance and more particularly the muscles solicited during the effort. It can be the calves (via a leggings or tights), thighs and / or glutes (via a shorts or tights).

By placing this association at the level of a T-shirt, it improves the posture maintenance during the exercise which avoids the subsidence of the athlete in endurance.

Moreover, by being placed on areas of the irrigation circuit of the muscles and tendons, this combination helps to improve the blood exchanges and thus the improvement of the functioning of the muscle (supply of oxygen, evacuation of toxins ...) .

The following tables provide different perimeters of a member of the user defined in a standardized way for a size indicated on the label of a category of clothing. These dimensions correspond to standardized values for men's clothing. The standards define both a maximum perimeter and a minimum perimeter of the limb for a size indicated on the garment label. The tables also provide the minimum and maximum perimeter perimeters of the garment section intended to surround the limb, for each size indicated on a label. Since a compression garment is intended to compress a limb of the user, the perimeter of the limb for which the garment is intended is always greater than the perimeter of the section of the garment that is to surround it. The tables also include the ratios between the perimeter of a limb corresponding to the standardized indication on the perimeter of the section of the garment intended to surround the limb. For a given fabric, these ratios directly translate the compression ratio exerted on the part of the body that the fabric surrounds.

Indeed, compression of a compressive garment is determined, on the one hand, by the material of the fabric and more particularly by its elasticity and its stretch, and on the other hand, by the compression ratio defined above, namely, the ratio between the perimeter of the body part surrounded and the perimeter of the garment at that level. Thus, one can achieve the same compression with a high compression ratio by using an elastic fabric or with a lower compression ratio by using a stiffer fabric. It should be noted that, the higher the compression ratio, the more elastically stresses the fabric, at the risk of exceeding its elastic limits. It follows a risk of deterioration of the garment or no longer have compression after a few uses. It is therefore advantageous that the compression ratio remains below a determined value related to the elastic characteristics of the fabric. A max compression ratio of 1.3 constitutes a satisfactory extreme limit whatever the nature of the fabric.

Conversely, the lower the compression ratio, the more the material of the fabric is rigid. This results in discomfort when the user puts on the garment because it is not very extensible. As a result, the garment adapts poorly to variations in the morphology of the user. The garment may lose its compression feature or may no longer be worn by the user. It is therefore advantageous that the compression ratio is greater than a determined value. A compression ratio min of 1.05 is a satisfactory extreme mark whatever the nature of the fabric.

A good compromise is a compression ratio of between 1.08 and 1.2, regardless of the size of the garment.

To characterize the compression, a compression level expressed in millimeters of mercury (mmHg) or hectoliters Pascal (hPa) is determined. The conversion between these two units is as follows: 1 mmHg equals 1.333 hPa.

To obtain the desired beneficial effects, compression at the calves, thighs or chest should be greater than 5 mmHg (eqv 7 hPa). It is preferable that it is less than 20 mmHg (eqv 27 hPa), because beyond that, some legislations require a medical prescription. In addition, too high a compression level can interfere in the effort and cause bad feeling of the user being too oppressed. Advantageously, the compression at these parts of the body is between 10 mmHg and 15 mmHg (13.5 hPa and 20 hPa), a level for which good results are observed.

From the foregoing, the garment advantageously comprises a fabric whose characteristics make it possible to obtain, with a compression ratio varying between 1.08 and 1.2, a compression level of between 5 and 20 mmHg. Preferably, the compression level obtained is between 10 and 15 mmHg.

The measurements of perimeters in the following tables are expressed in centimeters, they correspond to a male garment, for a given material material. Bib:

The thigh circumference corresponds to the circumference of the thigh of the user or thighbelt measured 2.5 cm under the groin. On reading the previous table, it can be seen that a bib of size M, that is to say expected for a user whose leg circumference is between 56 and 59 cm, should have a thigh of between 42 and 57 cm. For the user to benefit from the advantages of the invention, it is desirable for his thigh circumference to be greater than the leg circumference of the shorts in a ratio of at least 1, 01. Preferably, this compression ratio, defined between the thigh of the user and that of the shorts must be greater than, 09.

In practice, a leggings sold in the trade is provided with a size tag including a standard size indication, which corresponds, among other things, to a minimum perimeter of the thigh of the user (Little). This bib presents, by its construction, a given measurement of thigh circumference (Pce).

Note that in some configurations, there is no compression, for example, a shorts size M with a maximum leg circumference (57 cm) used with a person whose thigh circumference is minimum (56 cm) . In this case, the invention does not produce all the expected effects because it is found in conditions similar to the use of a garment comprising a far infrared mineral material without compression. This extreme configuration is still statistically rare. The previous table illustrates a range of shorts allowing the choice of a model according to the morphology of the user to obtain a compression of the member concerned in the majority of the cases (more than 95% of the cases will have a compression).

Good results are obtained with a shorts whose compression ratio is of the order of 1, 15 regardless of size. The dimensions of the different sizes of such a shorts are listed in the last row of the table above.

A garment comprising a far infrared mineral material and a compression produces the desired effects. Consequently, the coating reproduces the invention, even if, in certain configurations (user having another morphology, smaller thigh circumference), there is no compression of the part of the invention. body unless an indication, worn on the garment, explicitly excludes configurations for which there is compression.

Figure 3 illustrates an example of shorts 11 provided with a label 7 indicating a standardized size. The outline 21 in broken line corresponds to the section where the thigh circumference is measured.

Leggings:

The calf circumference corresponds to the perimeter of the widest section of the user's calf or leg.

For the user to enjoy the advantages of the invention, it is desirable that his calf circumference is greater than the calf circumference of the leg in a ratio at least equal to 1.03. Preferably, this compression ratio, defined between the calf of the user and that of the leg should be greater than 1, 08.

In practice, the leggings sold in the trade are provided with a size tag comprising a standardized size indication, which corresponds, among other things, to a minimum perimeter of the user's calf circumference (Pmu). This leg has, by its construction, a given measure of calf circumference (Pmj). The benefits of the invention will be particularly interesting when the compression ratio Pmu / Pmj will be greater than 1.03.

Note that in some configurations, there is no compression, for example, a size M leg with a maximum calf circumference (37 cm) used with a person whose calf circumference is minimum (36 cm) . In this case, the invention does not produce all the expected effects because it is found in similar conditions to the use of a garment equipped with far infrared mineral material without compression. This extreme configuration is still statistically rare. The previous table illustrates a range of leggings allowing the choice of a model according to the morphology of the user to obtain a compression of the member concerned in the majority of the cases (more than 95% of the cases will have a compression). We get good results with a leggings whose ratio is of the order of 1, 08 regardless of size. The dimensions of the different sizes of such a leg are listed in the last line of the table above.

A garment comprising a far infrared mineral material and a compression produces the desired effects. Consequently, the coating reproduces the invention, even if, in certain configurations (user having another morphology, smaller calf circumference), there is no compression of the part of the body unless an indication, worn on the garment, explicitly excludes configurations for which there is compression.

FIG. 4 illustrates an example of a leggings 12 provided with a label 7 indicating a standardized size. The outline 22 in broken line corresponds to the section where the calf circumference is measured.

T-shirt :

The chest circumference is the section of the user or the T-shirt measured under the armpits.

In order for the user to benefit from the advantages of the invention, it is desirable for his chest circumference to be greater than the t-shirt's chest circumference in a ratio of at least 1, 01. Preferably, this compression ratio, defined between the chest of the user and that of the T-shirt must be greater than 1, 09.

In practice, a commercial T-shirt is provided with a size label including a standardized size indication, which corresponds, inter alia, to a minimum perimeter of a user's chest (Ppu). This T-shirt has, by its construction, a given measure of bust (Ppt). The benefits of the invention will be particularly interesting when the compression ratio Ppu / Ppt will be greater than 1, 01.

Note that in some configurations, there is no compression, for example, a T-shirt size M with a maximum chest (102 cm) used with a person whose T-shirt is minimum (97 cm). In this In this case, the invention does not produce all the expected effects because one finds oneself in conditions similar to the use of a garment equipped with far infrared mineral material without compression. This extreme configuration is still statistically rare. The previous table illustrates a range of T-shirts allowing the choice of a model according to the morphology of the user to obtain a compression of the member concerned in the majority of the cases (more than 95% of the cases will have a compression ).

We get good results with a shorts whose ratio is of the order of 1, 2 regardless of size. The dimensions of the different sizes of such a T-shirt are repeated in the last line of the table above.

A garment comprising a far infrared mineral material and a compression produces the desired effects. Consequently, the coating reproduces the invention, even if, in certain configurations (user having another morphology, smaller chest size), there is no compression of the part of the body unless an indication, worn on the garment, explicitly excludes configurations for which there is compression.

FIG. 5 illustrates an example of a T-shirt 13 provided with a label 7 indicating a standardized size. The outline 23 in dashed line corresponds to the section where is measured the bust.

In the example illustrated in Figures 1 and 2, the composite material 3 advantageously forms a slight relief relative to the outer surface of the fabric 2. Such a relief is likely to improve the strength of the garment. The amount of radiation generated is proportional to the area covered and the thickness deposited. The composite material 3 may also protrude from the inner surface of the fabric 2, either by completing the projection formed by the relief of the outer surface or by replacing it. The projection made on the inner surface may be of less amplitude than that made on the outer surface to not affect the comfort of the user.

As illustrated in FIG. 2, the fabric 2 has coated areas 6 of composite material 3 and uncoated areas 5. The coating of composite material may or may not pass through the fabric 2 and may or may not penetrate the interior of the fabric. fibers of the fabric 2.

In the example illustrated, the composite material 3 advantageously forms patterns spaced from each other. The illustrated patterns are hexagonal but any other shape can of course be used. The spacing of the patterns spares spacing zones 4 of the fabric 2 uncoated with composite material 3, which improves the breathability and elasticity of the garment. The use of patterns also makes it possible to reduce the mechanical stress in the composite material 3. The proportion of far infrared mineral materials in the composite material 3 can be increased to improve the physiological effect of the garment, without impairing its elasticity or its life.

As illustrated, the composite material patterns 3 are advantageously spaced from each other in all directions in the plane of the fabric 2. The patterns are thus surrounded by a fabric portion 2 uncoated composite material. The spacing between the patterns may advantageously be greater than 1, 5 mm, the garment then having large areas of fabric 2 having a high elasticity. The surface of each pattern will advantageously be less than 2 cm ² , so as to reduce the mechanical stresses in the patterns and so as not to unduly alter the elasticity of the garment.

To confirm the beneficial effects of combining compression with the use of far infrared mineral material in a garment, endurance tests were performed.

This test consisted of running a sportsman on a treadmill over a distance of 40 km and with a vertical drop of 1,000 meters. Throughout this race, a camera films the sportsman from different angles. Post-stroke image processing measures the evolution of posture through multiple angles formed by the human body.

The knee bend angle is the minimum angle between the tibia and the measured thigh on one leg as long as the foot remains in contact with the ground.

The angle of oscillation of the knee corresponds to the minimum angle between the tibia and the measured thigh of the back on one leg as long as the foot remains in contact with the ground. Lateral movement of the knee is analyzed.

The angle of flexion of the hip corresponds to the minimum angle between the trunk and the thigh measured in profile on one leg sloping forward.

These 3 angles are evaluated before and after the race.

The athlete performs several times this race but with different clothes. In a first case, with usual clothes A. In a second case, with leggings B, a bib B and a T-shirt B, these clothes B comprising a far infrared mineral material and a compression level of the order of 5 mmHg. In several other cases, with leggings C, a shorts C and a T-shirt C, these clothes C comprising a compression level of the order of 15 to 20 mmHg.

The analysis of the results shows that the use of clothing B including a slight compression and a far infrared mineral material brings more stability and less fatigue to the athlete. Indeed, these 3 angles (the knee angle of the knee, the angle of oscillation of the knee and the angle of flexion of the hip), decreases of the order of 1 to 2 degrees, between the beginning and the end of the test, when the runner wears the clothes A or C. On the other hand, these 3 angles are stable or increase slightly, between the beginning and the end of the test, when the runner wears clothes B.

The combination of compression with a far infrared mineral material in a garment therefore provides a benefit in terms of endurance resistance compared to the use of a compression garment only.

The textile material can be obtained at the end of a process comprising a step of coating the fabric with a precursor coating composition of a composite material. The method of manufacturing the textile material may comprise the following steps:

Preparation of a precursor coating composition of the composite material, the coating composition comprising at least: a carrier liquid, ceramic particles dispersed in the carrier liquid and a polymer, or its precursor, dispersed or dissolved in the carrier liquid ,

Coating the fabric with said coating composition,

Evaporation of the carrier liquid,

Optionally, crosslinking the polymer, or its precursor, to form the matrix of the composite material.

The coating of the fabric may be carried out by any appropriate means, for example by a method of transfer by screen printing or by printing. The coating can be performed on the fabric 2 before cutting the various components of the garment, then the assembly of two fabric edges of one or more components of the garment.

The label providing a standardized size indication may be set at any appropriate time in the process.

A compression garment necessarily exerts pressure on a part of the body that it surrounds, so as to improve the blood circulation.
