These methods are often expressed in the following terms: POY (partially oriented yarn), FOY (fully oriented yarn), ISD (integrated spinning) and HOY (highly oriented yarns with a spinning rate greater than 5 5 00 m/min). These yarns can also be textured, depending on the intended use. The yarns obtained by such methods are particularly suitable for the manufacture of fabric surfaces, whether woven or knitted. According to the invention, the PEBA thermoplastic polymer matrix can be used to produce monofilament or monofilament yarns, multifilament or multifilament yarns, continuous fibers (on reels) and/or discontinuities (short cuts) )fiber. Chopped PEBA fibers are particularly suitable for blending with natural fibers. A method particularly suitable for the manufacture of PEBA monofilaments and multifilaments is described in patent application US 2010/0119804. For individual fibers or monofilaments, the linear density can range from 1.5 dtex to 100 dtex/ Filament, high linear density is particularly suitable for industrial applications. The multifilament yarn preferably has a linear density of 6 dtex/fibres or less, more preferably 1.5 dtex/filament or less. To produce the fibers, the filaments may be incorporated into the form of a yarn bundle or a gauze directly after spinning or after stretching, texturing or crimping and chopping. The resulting fibers can be used to make non-woven or staple fiber yarns. The composition can also be used to make tufts. The yarns, fibers and/or filaments of the present invention may be subjected to various treatments such as, for example, stretching in a continuous step, or thereafter, by falling, oiling, gelling, texturing, crimping, drawing, fixing or relaxing heat treatment, Filament, twisting and/or dyeing. In the case of dyeing, in particular -18-201207175, a reductive dyeing or jet dyeing method can be mentioned. Preferred dyeing systems are acid dyeing, metal dyeing, and non-metal dyeing. The invention also relates to a fabric made from a PEBA substrate or a thermoplastic composition comprising the PEBA of the invention, which is obtained by a forming operation using a method selected from the following extrusion methods: such as extruded sheets and films: molding methods , such as compression molding; and injection methods, such as injection molding. Thus, a film can be produced by using a sheet die by the aforementioned method. The resulting film can be subjected to various processing steps such as uniaxial or biaxial stretching treatment, stabilization heat treatment, antistatic treatment or sizing treatment. The fabric comprising the hydrophobic PEBA of the present invention provides a cooling or cooling effect under specific conditions: the cooling effect is in contact with the aqueous medium with a hydrophobic PEBA-based fabric material (by simple contact or by dipping, spraying or even soaking) After that, it is irrelevant to the way the aqueous medium is added to the fabric material. The term "aqueous medium" is understood in the context of the present invention to mean a liquid or a gas, a steam or even a solid comprising at least 85% by weight of water, preferably at least 90% by weight, based on the weight of the medium, more preferably at least 95% by weight of water, the temperature of the aqueous medium is preferably in the range of 1 ° C to Tm - 2 ° C, preferably in the range of 15 ° C to TmdCTC, and Tm is the melting point of the fabric material of the present invention. The aqueous medium can naturally fill the fabric or can naturally come into contact with the fabric material. This is the case, for example, of sweat on the outer garment. The aqueous medium can also be deliberately added to the fabric by any means such as impregnation, soaking or spraying of an aqueous medium in the form of a gas, vapor or liquid or by any other method of adding liquid, gas or steam to the fabric material -19-201207175. This is a medical, pharmaceutical or cosmetic active agent or may be added, for example, to the flavor of a bandage or a cold wipe. The term "ambient temperature" is understood in the context of the present invention to mean the temperature of the air or medium surrounding the fabric, whether the temperature is controlled (air conditioning, cold room), programmed (process or operating temperature of the device) or not Controlled (due to external geographic and climatic conditions). More specifically, ambient temperature is understood to mean a temperature in the range of -60 ° C to 150 ° C, preferably -40 ° C to 140 ° Range C. The fabric material of the present invention comprising at least 50% hydrophobic PEBA can withstand such temperatures, and PEBA retains all of its properties (especially flexibility and its size) at such temperatures. Cooling to a temperature below ambient temperature for at least 15 minutes, preferably at least 30 minutes, more preferably at least one hour, and more preferably at least two hours, after the contacting operation, the ambient temperature is in the range of 10 to 80 °C Preferably, it is 10 to 50 ° C, more preferably 15 to 40 ° C. Advantageously, the material has an acceleration at a temperature below ambient temperature (preferably below 20 ° C) and desorption for a long time and Evaporation of the aqueous medium in the form of a cold gas The invention also relates to a fabric or fabric in the form of yarns, fibers and/or filaments as defined above, at least partially made from hydrophobic PEBA. Such fabrics may be woven or woven surfaces, such as woven, knitted, Non-woven or mat surface. The fabric is useful for use in medicine, make-up, hygiene, luggage, fashion women's wear, clothing, indoor or household equipment, interior furnishings, carpets, automotive or industrial applications, especially industrial filtration, agriculture. And/or building materials -20- 201207175. Such fabrics may, for example, be carpets, furniture covers, surface coverings, sofas, curtains, mattresses and pillows, beverage coolants, line cooling jackets and medical fabric materials. It is advantageous to constitute a felt, a filter, a film, a gauze, a cloth, a net, a net, a bandage (especially a bandage for soothing pain or burns), a layer, a woven fabric, a knitted fabric, a clothing article, a garment, a pantyhose, and a long Stockings (especially supportive stockings), bed linen items, furniture items, napkins, packaging, curtains, linings, functional engineering fabrics, geotextiles and/or Agricultural fabrics. The cooling effect of nets, nets, knitted fabrics or porous membranes using monofilament or multifilament yarns is particularly surprising. For example, in such a structure immersed in hot water of about 4 ° C and After a brief drying, the cooling effect is produced in a few seconds, and the surface temperature of the fabric is reduced to 16 ° C in less than about ten seconds. The same result is obtained in water immersed in an ambient temperature (for example, 20 ° C). Hot water at temperatures above 30 ° C provides an additional surprising effect. Advantageously, fabrics containing PEBA-based fibers, filaments and/or films have a high specific surface area. This has been shown to further increase water solubility. The evaporation rate of the liquid on the surface of the fabric comprising such fibers and/or filaments of the invention. Similarly, the fiber or filament surface may have a specific structure, such as grooves, especially grooves such as straight lines, ellipses, etc., to increase The evaporation rate of the fabric material is invented, thereby increasing the cooling effect. The fabrics made from the hydrophobic PEBA of the present invention are preferably predominantly (including at least 50% by weight of PEBA) and have other preferred properties. It is light, flexible and soft to the touch; it is resistant to tearing, cutting, abrasion and lifting -21 - 201207175 balls. Advantageously, the fabric further comprises: natural fibers such as cotton, wool and/or silk fibers; rayon fibers made from natural materials; mineral fibers such as carbon, glass, ceria and/or magnesium fibers; metal fibers; And/or synthetic fibers other than PEBA fibers. Synthetic fibers may especially comprise polyesters, polyethers, polyetheresters, polyamides or acrylic fibers, or any other synthetic material commonly used in the field of fabrics. The fabrics of the invention may especially comprise hydrophobic PEBA and hydrophilic synthetic fibers. Combination (eg hydrophilic PEBA fiber). The latter acts as a moisture transport agent. Hydrophilic synthetic fibers absorb moisture and, upon contact with PEBA, cause evaporation to cool the fabric. As an example of a structure that can be used in outer garments, 'hydrophilic fibers are primarily in contact with the skin (eg, inside the T-shirt) to absorb moisture' and transport it to the hydrophobic PEBA located on the side of the environmental medium, primarily on the outside of the garment. fiber. The fabric of the present invention may have a sandwich structure comprising a primary hydrophilic fiber sandwiched between two layers of predominantly hydrophobic fibers, comprising at least 1% hydrophobic PEBA, or conversely, comprising a layer sandwiched between two layers of primary hydrophilic The predominantly hydrophobic fiber between the fibers, comprising at least 1% hydrophobic PEBA. The term "primary" as used herein means that the layer contains more than 50% by weight of hydrophobic or hydrophilic fibers, as the case may be. The present invention uses a hydrophobic PEBA-based fabric to produce an amazing dry-cooling effect, unlike pure hydrophilic fabrics that accumulate water and cause a cooling effect due to the presence of water. PEBA evaporates water more quickly, causing a strong cold feel on the surface of the fabric, and the wetting effect of the fabric disappears almost instantaneously. -22- 201207175 It is advantageous that the fabric comprises a synthetic material obtained from a biological resource raw material. The fabric is preferably made only from biological resource materials. “Recycled raw material” or “biological resource raw material” is understood to mean carbon containing biological resources or regenerative carbon. Different from materials obtained from fossil materials, by regeneration The material consisting of raw materials contains 14c. "Renewable carbon content" or ''Bioresource carbon content" is determined by ASTM D 68 66 (ASTM D 6866-06) and ASTM D 7026 (ASTM D 7026-04) . The first standard describes a test for measuring the 14C/i2C ratio of a sample, and compares it with the 14 C / 1 2 C ratio of a reference sample of 100% biological resources to produce a biological resource source carbon in the sample. Relative percentage. The standard is based on the same concept as carbon 14 dating, but the dating equation is not applied. The calculated ratio is called “PMC” (the percentage of contemporary carbon). If the material to be analyzed is a mixture of biomaterials and fossil materials (no radioisotopes), the resulting PMC tether is directly related to the amount of biomaterial present in the sample. The ASTM D 6866 standard provides several techniques for measuring the l4C isotope content, either based on LSC (liquid scintillation counting), or liquid scintillation spectroscopy, or based on AMS/IRMS (accelerator mass spectrometry combined with isotope ratio mass spectrometry). A measurement method that is more advantageous for use in the context of the present invention is a mass spectrometer described in the ASTM D 68 66-06 standard (i.e., accelerator mass spectrometry). To provide an example, at least a portion of the fabric of the present invention comprising PA-1 based PE-1 is derived from a biological resource feedstock and has a biological resource carbon content of at least 1%, corresponding to a 12C/14C isotope ratio of 1.2 X 1 〇 _14. Preferably, in the fabric of the present invention, at least 50% of the total carbon mass is the biomass carbon mass, corresponding to a 12C/14C isotope ratio of at least 0.6 X 10_12. When PEBA has -23-201207175 PA-11 block and PE block, including P03G, PTMG and/or PPG from renewable raw materials, this content is more favorable - especially up to 100% - corresponding The 12C/14C isotope ratio is 1.2 X 10_12. The fabric of the present invention can thus be made from 1% bioresource carbon or vice versa from a mixture with fossil source carbon. [Embodiment] The following examples illustrate the invention without limiting its scope. All percentages are by weight unless otherwise indicated. Measure the temperature of various fabrics. Fabrics made from PEBA in accordance with the present invention are compared to fabrics based on other materials commonly used in fabrics, 卩PES (polyester) PA (polyamide) and cotton. In the examples of the present invention, Exl, Εχ2, Εχ3, Εχ4 and Εχ5 and Comparative Example Cp2, PEBA is PA12-PTMG, that is, it contains ΡΑ-12 block and PTMG block. EXAMPLES In Exl.l, Ex2.1 and Εχ3·1, PEBA is PA-1 1/PTMG. In Comparative Examples 3, 4, and 5, what are the individual PEBAs? Eight-6/PTMG, PA-12/PEG and PA-6/PEG. Comparative Example Cpl is a polyester, Cp6 is a PA-11, a Cp7 cotton, and a Cp8 is a Platamid® H005 trademark of PA-6/6, 6/12 copolyamine. The contents of PA and PE blocks (in weight percent) are listed in Table 1. The temperature measurement was carried out on a fabric using an infrared gun (Col e-Parmer®). The aqueous medium used in the examples is liquid water. -24- 201207175 The fabric material was a lightweight network weighing 80 g/m2 in all tests, except for Example 2. Example 2 is a non-woven fabric composed of a relatively dense network of fibers and having a large weight, which is more difficult to contact with an aqueous medium and has a smaller contact area. The fabric is less impregnated with an aqueous medium. Process: 23 ° C ambient temperature: - at TO: immerse the fabric material in water (material / aqueous medium contact) for 5 seconds; - dry for 5 seconds; and then - use an infrared gun to measure the fabric surface temperature, individually at 3 0 seconds, 30 minutes '1 hour, 1 hour 30 minutes and then 2 hours. The results are shown in Table 1 below. Table 1: Characteristic analysis and measurement of fabric cooling effect

The comparative fabrics Cpl to Cp6 were swollen, twisted and had a soaked &'s heavy appearance; after contact with the liquid, the fabric temperature observed was zero (at Cpl) or very small (Cp2 to Cp6). In contrast, the embodiment of the present invention uses a hydrophobic PEBA-based fabric "Ex" to cool and has a cooling effect for at least 2 hours, with a dry, pleasant and soft feel while remaining extremely light. Its temperature is lowered by 5 to 7 ° C with respect to the initial temperature of 23 ° C over at least 1 h 30, corresponding to the ambient temperature, even after impregnation with water at a temperature of 30 ° C. Under gentle shaking of the fabric of the present invention with hydrophobic PEBA as the substrate, for example at TO + 1 h 30, it was found that the temperature was again lowered to 16 ° C because of the additional evaporation produced. In Table 2 below, various fabrics (networks) made from cotton (Cp7), PA-6/6, 6/12 copolyamine (Cp8) and hydrophobic PEBA (Exl) were weighed according to the same procedure.
