Definitions
- the present invention relates to the technical field of fibers or filaments having acid and / or basic gas absorption capacities, in particular related to unpleasant odors resulting from perspiration.
- the first textile layer worn by a user during the practice of a sport is the preferred receiver of sweat and odorant molecules, especially from the degradation of proteins contained in sweat by the bacteria present on the skin. This textile layer retains these odorous molecules and therefore feels bad after a workout, especially when it dries, which requires washing before the next session. It is even common that a polyester textile layer exudes unpleasant odors already during the workout.
- Textile materials do not react in the same way with respect to odors. Natural materials, especially wool-based, feel little, if any, odors, especially related to perspiration.
- textiles obtained from fibers and / or filaments functionalised with cyclodextrin cages, or nanoparticles of charcoal, bamboo or coconut, or uses coffee-based fibers.
- these solutions are not sustainable since the functionalization agents are eliminated as and when washes, and / or have in addition a limited efficiency of odor absorption and / or modify the tactile properties of textiles for example in them. rigidifying especially with regard to cyclodextrins.
- Another solution is to introduce odor absorbing materials, such as natural fibers, for example cotton in polyester-based textiles. But this solution has the disadvantage that it is expensive and does not allow rapid drying of the textile article and therefore also an accelerated evacuation of sweat. However, rapid drying and sweat evacuation properties are particularly sought after in the case of technical textile articles intended for the practice of a sport. In addition, cotton tends to pelletize.
- antibacterial agents on textile articles, such as silver nanométaux, copper, zinc oxide, titanium, zirconium or platinum.
- these antibacterial agents act directly on the bacteria that are in contact with the skin. This solution is therefore valid only for textile articles intended to be worn very close to the body, such as socks, but is not valid, or significantly less, for T-shirts for example.
- legislation on biocidal agents is becoming stricter because it affects cutaneous bacterial flora.
- EP 0.792.957 B1 discloses the manufacture of a fiber having acidic and basic gas absorption properties both through carboxylic groups (-COOH) and carboxylate groups (-COO-) complexed with a metal salt, for example a sodium salt, in order to remove odors (see [0002]).
- a metal salt for example a sodium salt
- This fiber is obtained by modifying a base fiber comprising more than 40% by weight of polyacrylinotrile (PAN) with hydrazine (NH 2 -NH 2) in order to crosslink the latter and increase its nitrogen content between 1% and 8% of its total weight.
- PAN polyacrylinotrile
- NH 2 -NH 2 hydrazine
- the nitrile groups remaining on said fiber are then hydrolysed using a basic solution of a metal salt, for example sodium hydroxide or potassium hydroxide.
- the fiber is then immersed in a nitric acid solution for 30 minutes and then washed (see Example 1, [0048]).
- EP 0.792.957 B1 applies only to a polyacrylonitrile fiber obtained by definition by coagulation of polyacrylonitrile (PAN) and then spinning it.
- the resulting fibers have a pinkish color and do not dye or are very difficult.
- these fibers do not have sufficient toughness to constitute only a wire, it is therefore necessary to use them mixed with other fibers and / or filaments to overcome their limited mechanical properties.
- the mixture of acrylic fibers with synthetic fibers, such as polyester fibers, for example is complex because of dyeing problems (the acrylic fibers are often mixed with wool and do not withstand a temperature greater than 100 ° VS).
- yarns comprising polyacrylonitrile fibers, such as spun yarns of fibers tend to pelletize and are less abrasion resistant.
- the technical articles in sport are mainly in synthetic materials such as polyester or polyamide and not based on cotton or viscose or acrylic fibers for reasons of cost and efficiency in terms of speed of drying and moisture evacuation but also ease of implementation, especially with regard to mechanical performance and dyeing.

- the MFI values shown in Table 1 are measured for the compositions (Tests 1 to 9) and the polyester only (PET) for the test 10 (preferably Melt Flox Index or melt flow index is measured indifferently according to US Pat. one of the standards ISO 1133 - February 1, 2012 and ASTM D 1238 - August 2013, at 270 ° C under a mass of 2.16 kg). Acrylate mmol tests / g T5 (° C) die pressure measured at
- Table 2 above represents the theoretical molar quantities of acrylate functions present relative to the mass of the first and second polymers (A) and (B), the acrylate functions being here supported in these examples by the first and second polymers (A). ) and B). Note that the higher the amount of second copolymer B increases, the pressure in the extrusion die increases compared to the setpoint of 5.7 bar and the temperature T5 in the extrusion die also increases.
- Tests 1 to 4 in Table 3 below correspond to compositions of tests 1 to 4 defined in Table 1. These compositions were extruded and spun using a single-screw extruder comprising an extrusion die having a plurality of spinning orifices and a set of filters. Drawing and spinning means are disposed at the outlet of the extrusion die, and include in particular a nozzle sending an air jet in order to intermingle the filaments. The son formed are thus multifilament son comprising 48 filaments. The filaments are cooled using a cold air flow. At the exit of the spinning and drawing stages, the yarns are sized, in particular with a sizing agent (such as that marketed under the reference Fasavin KB 88) at a level of 10% by weight relative to the total mass of said yarn. .
- a sizing agent such as that marketed under the reference Fasavin KB 88
- Table 3 lists the titers and tenacities that were measured on the different yarns obtained according to the drawing techniques used.
- the structure of the yarns obtained was also characterized by analyzing sections of filaments under a scanning electron microscope. There is thus observed the formation of nodules comprising the first copolymer Has disposed in a kind of pocket whose "shell" is formed of the second copolymer B, the second copolymer B thus acting as a coupling agent with the polyester matrix.
- a yarn comprising 48 filaments for 150 deniers according to test 4 defined in Table 3 in DTY is knitted (jersey weave).
- the density of the knit is 31 g / m 2 .
- Samples 6cm * 6cm are prepared and immersed for 45 minutes in a bath comprising 5g / l of sodium hydroxide at 85-90 ° C.
- a pH-metric determination made it possible to measure a soda consumption of 50 +/- 10 meq / kg of knitting (by measuring the concentration of sodium hydroxide in the bath after the saponification stage).
- the mass loss of the knit after saponification is about 1.8%.
- the quantity in meq of acrylate and therefore saponifiable functions is 168.5 mmol per kg of knit tested.
- measured sodium consumption makes it possible to conclude that about 30% of the acrylate functions have been saponified in the form of carboxylate functions.
- a pH-metric determination made it possible to measure an average acid consumption of 15 +/- 5 mmol H + / kg of knit. This acid consumption corresponds to about 30% of the 50 meq of sodium hydroxide consumed in the saponification stage per Kg of knit.
- the absorption value of a standard knit comprising exclusively polyester is less than 40%.
- the knits described above with reference to paragraph III having undergone a saponification step, and an acidification step, have acetic acid absorption values of 88% +/- 2%.
- the acidification step therefore makes it possible to improve the absorption properties of acetic acid.
- the acid gas absorption mechanisms in this example acetic acid, are related to acid-base reactions with the carboxylic and carboxylate functions supported by the filaments.
- the reaction between a carboxylate function and acetic acid generates a nonvolatile metal carboxylate (CH 3 COONa) which would explain the reduction of perceived odors. This would result in deodorization of the gas by salification.
- CH 3 COONa nonvolatile metal carboxylate
- the re-initialization of the textile articles can be obtained by rinsing with running water (for example during a domestic wash) or by drying the textile article which makes it possible to displace the acid-base balance and to evaporate acid gas.
- the yarns according to the invention and implemented in the knitted and tested samples are integrally in the extrudable-spinnable composition according to the invention.
- the extrudable-spinnable composition according to the invention is co-extruded with another polymeric composition so as to form a first polymeric structure consisting of said matrix (then forming the mantle for example) parallel to a second polymeric structure consisting of the second co-extruded polymeric composition (for example made up of more than 95% by mass of polyester).
