Films may thus be obtained by the aforementioned processes using a sheet die. The films obtained my undergo various treatment steps, such as a uniaxial or biaxial drawing treatment, a stabilizing heat treatment, an antistatic treatment or a sizing treatment.
  • the fabrics comprising hydrophobic PEBA according to the invention provide a cold or cooling effect under certain conditions: the cooling effect is caused after the hydrophobic-PEBA-based fabric material has been brought into contact (either by simple contacting or by impregnation, spraying or even dipping) with an aqueous medium, irrespective of the way in which the aqueous medium has been added to the fabric material.
  • aqueous medium is understood in the context of the invention to mean a liquid or a gas, vapor, or even a solid, said medium comprising at least 85 wt % water, preferably at least 90 wt % water and more preferably at least 95 wt % water relative to the weight of the medium, and the temperature of the aqueous medium preferably lies in the 1° C. to T m -20° C. range, preferably the 15° C. to T m -20° C. range, T m being the melting point of a fabric material according to the invention.

This is the case of a medical, pharmaceutical or cosmetic active agent or of a perfume that may for example be added to a bandage or a cooling wipe respectively.
  • ambient temperature is understood in the context of the invention to mean the temperature of the air or the medium surrounding the fabric, whether this temperature is controlled (air-conditioning, cold chamber), programmed (operating temperature of a process or device) or not controlled (due to the external geographical and weather conditions). More precisely, the ambient temperature is understood to mean a temperature lying within the ⁇ 60° C. to 150° C. range, preferably the ⁇ 40° C. to 140° C. range.
  • the fabric materials according to the invention comprising at least 50% hydrophobic PEBA are capable of withstanding these temperatures, the PEBAs retaining all their properties (especially flexibility and their dimensions) at these temperatures.

  • said material is such that it has accelerated and prolonged properties of desorbing and evaporating said aqueous medium in cold gas form from a temperature below the ambient temperature, preferably below 20° C.
  • the present invention also relates to a fabric or a fabric article obtained at least partly from hydrophobic PEBA, in the form of yarns, fibers and/or filaments as defined above.
  • These articles may be fabrics or fabric surfaces, such as woven, knitted, nonwoven or matt surfaces.
  • Said fabric is advantageously used in the medical, cosmetic, pharmaceutical hygiene, baggage, confection, clothing, domestic or household equipment, furnishing, carpet, automotive or industrial fields, especially for industrial filtration, agricultural and/or building matter.
  • the fabric according to the invention advantageously constitutes a felt, a filter, a film, a gauze, a cloth, a web, a net, a bandage, especially a bandage for soothing pain or burns, a ply, a woven, a knit, an article of clothing, a garment, a pair of tights, stockings, especially support stockings, an article of bed linen, an article of furniture, a napkin, a package, a curtain, an interior lining, a functional engineering textile, a geotextile and/or an agricultural textile.
  • the cold effect is particularly surprising on a web, a net, knitted fabric using monofilaments or multifilaments or on a perforated film.
  • these structures have been immersed in hot water at around 40° C. and then briefly dried, they produce a cold effect in a few seconds, the surface temperature of the fabric being lowered to 16° C. in less than around ten seconds.
  • Immersion in water at the ambient temperature gives the same results.
  • Hot water, especially at a temperature above 30° C. provides an additional surprise effect.
  • said fabric comprising PEBA-based fibers, filaments and/or films has a high specific surface area. It has been demonstrated that this further increases the rate of evaporation of an aqueous liquid at the surface of the textile fabric comprising these fibers and/or filaments according to the invention.
  • the surface of the fibers or filaments may have a particular structure such as grooves, especially straight, ellipsoidal, etc. grooves, to increase the rate of evaporation and therefore the cold effect of the fabric materials according to the invention.
  • These fabrics according to the invention manufactured from hydrophobic PEBA, preferably predominantly so, (comprising at least 50 wt % PEBA) also have other advantageous properties. They are light, flexible and soft to the touch; they are resistant to tearing, cutting, abrasion and pilling
  • said fabric further includes: natural fibers, such as cotton, wool and/or silk fibers; artificial fibers manufactured from natural raw materials; mineral fibers, such as carbon, glass, silica and/or magnesium fibers; metal fibers; and/or synthetic fibers other than PEBA fibers.
  • the synthetic fibers may especially comprise polyester, polyether, polyetherester, polyamide or acrylic fibers, or fibers of any other synthetic material generally used in the fabric sector.
  • the fabrics according to the invention may especially comprise combinations of hydrophobic PEBA with hydrophilic synthetic fibers (for example hydrophilic PEBA fibers).
  • hydrophilic synthetic fibers for example hydrophilic PEBA fibers.
  • the latter act as a moisture transfer agent.
  • the hydrophilic synthetic fibers absorb the moisture and, on contact with the PEBA, the latter causes evaporation cooling the fabric.
  • the hydrophilic fibers are predominantly in contact with the skin (for example the inside of a T-shirt) in order to absorb the moisture and transfer it to the hydrophobic PEBA fibers that are predominantly on the outside of the garment, on the ambient medium side.
  • the fabrics according to the invention may have sandwich structures comprising a ply of predominantly hydrophilic fibers sandwiched between two plies of predominantly hydrophobic fibers, comprising at least 10% hydrophobic PEBA, or, conversely, comprising a ply of predominantly hydrophobic fibers, comprising at least 10% hydrophobic PEBA, sandwiched between two plies of predominantly hydrophilic fibers.
  • the term “predominantly” means that the ply contains more than 50 wt % of hydrophobic or hydrophilic fibers, depending on the case.
  • the hydrophobic-PEBA-based fabrics of the invention cause a surprising dry cold effect.
  • the hydrophobic PEBA evaporates the water more rapidly, causing an intense cold sensation on the surface of the fabric and making the wetted effect of the fabric disappear almost instantaneously.
  • said fabric comprises synthetic fibers obtained from bioresource raw materials.
  • the fabric according to the invention is manufactured solely from bioresource raw materials.
  • renewable raw materials or the expression “bioresource raw materials” is understood to mean materials that comprise bioresource carbon or renewable carbon. Unlike materials obtained from fossil materials, materials composed of renewable raw materials contain 14 C.
  • the “renewable carbon content” or “bioresource carbon content” is determined by applying the ASTM D 6866 (ASTM D 6866-06) and ASTM D 7026 (ASTM D 7026-04) standards.
  • the first standard describes a test for measuring the 14 C/ 12 C ratio of a specimen and compares it with the 14 C/ 12 C ratio of a reference specimen of 100% bioresource origin in order to give a relative percentage of bioresource carbon in the specimen.
  • the standard is based on the same concepts as in carbon 14 dating, but without applying the dating equations.
  • the ratio thus calculated is called the “pMC” (percent Modern Carbon). If the material to be analyzed is a mixture of biomaterial and fossil material (with no radioactive isotope), then the pMC value obtained is directly correlated with the amount of biomaterial present in the specimen.
  • the ASTM D 6866 standard provides several techniques for measuring the content of the 14 C isotope, these being based either on LSC (liquid scintillation counting), i.e. liquid scintillation spectrometry, or on AMS/IRMS (accelerator mass spectrometry coupled with isotope ratio mass spectrometry).
  • the measuring method preferentially used in the case of the present invention is mass spectrometry, described in the ASTM D 6866-06 standard (i.e. accelerator mass spectroscopy).
  • the fabrics of the invention containing PEBA based on PA-11 are at least partly obtained from bioresource raw materials and have a bioresource carbon content of at least 1%, corresponding to a 12 C/ 14 C isotope ratio of 1.2 ⁇ 10 ⁇ 14 .
  • at least 50% of the total carbon mass is bioresource carbon mass, corresponding to a 12 C/ 14 C isotope ratio of at least 0.6 ⁇ 10 ⁇ 12 .
  • This content is advantageously higher, especially up to 100%, corresponding to a 12 C/ 14 C isotope ratio of 1.2 ⁇ 10 ⁇ 12 in the case of PEBAs having PA-11 blocks and PE blocks comprising PO3G, PTMG and/or PPG obtained from renewable raw materials.
  • the fabrics according to the invention may therefore be made of 100% bioresource carbon or on the contrary result from a mixture with carbon of fossil origin.
  • the fabrics manufactured from PEBA according to the invention are compared with fabrics based on other materials normally used in fabrics, namely PES (polyester), PA (polyamide) and cotton.
  • the PEBA is PA12-PTMG, i.e. it comprises PA-12 blocks and PTMG blocks.
  • the PEBA is PA-11/PTMG.
  • the PEBA is PA-6/PTMG, PA-12/PEG and PA-6/PEG respectively.
  • Comparative example Cp1 is polyester, Cp6 is PA-11, Cp1 is cotton and Cp8 is a PA-6/6,6/12 copolyamide of Platamid® H005 trademark.
  • the temperature measurements were carried out on the fabric using an infrared gun (Cole-Parmer®).
  • the aqueous medium used in the examples was liquid water.
  • the fabric material was in the form of a light web weighing 80 g/m 2 for all the tests except in the case of example 2.
  • Example 2 was a nonwoven consisting of tighter fibers than those of the web and with a greater weight, making contact with the aqueous medium more difficult, and with a smaller contact area.
  • the fabric was less impregnated with the aqueous medium.
  • hydrophobic-PEBA-based fabrics of the examples according to the invention “Ex”, cooled and had a cooling effect lasting for at least 2 hours, had a dry, pleasant and soft feel, while remaining very light.
  • Their temperature dropped by 5 to 7° C. over at least 1 h 30 relative to the initial temperature of 23° C., corresponding to the ambient temperature, even after impregnation with water at a temperature of 30° C.
  • the PEBA fabric (Ex1) according to the invention had accelerated water evaporation properties, the water taking the form of cold gas at a temperature below 20° C., whereas the evaporation of water from a polyamide fabric or a cotton fabric was much slower.
  • the PEBA used in the composition of a fabric according to the invention had a surprising dry cold effect lasting for several hours and capable of being intensified and extended through the effect of movement (for example if it was shaken gently at T0+1 hours) or else through the effect of a further contact with an aqueous medium, such as liquid water, or the sweat of a sportsman for example.
  • the cooling effect of the fabric according to the invention is intensified and extended by shaking the fabric that has previously been brought into contact with an aqueous medium.
  • the behavior of the fabrics according to the invention is therefore the ideal behavior desirable for engineering fabrics, especially in the sports field, in particular for sports clothing.
