Definitions

  • the field of the present invention is that of crosslinkable liquid silicone formulations which can be used to form a coating which makes it possible to provide long-lasting functionalities to a large number of sportswear.
  • number of textile materials in particular those used in the field of sportswear (in English "sportwear”).
  • Many treatments are applied to textile materials, they provide them with additional functionalities such as softness, hydrophilicity, hydrophobia, oleophobia.
  • These treatments often consist of depositing on the textile surface polymers mainly of silicone type. For softness, these are long polydimethylsiloxane oils (or even polyorganosiloxane gums).
  • hydrophilicity they are amino silicone oils or polyether groups.
  • Organosilicon or purely organic fluorinated compounds are incorporated when seeking to provide oleophobia.
  • one of the characteristics sought is the permanence of the treatment. It is observed in practice that the many current formulations do not allow satisfactory durability to be achieved.
  • the main characteristics required are as follows: comfort, breathability, water repellency and a certain level of waterproofing: • • Comfort is provided mainly by the nature and type of textile used. In addition, these textiles may have elasticity properties. • Breathability is mainly ensured by the structure of the textile, in particular its open porosity.
  • waterproof-breathable membrane significantly reduces the intrinsic breathability of the textile and no longer allows the evacuation of heat and water in the event of moderate activity, strong to very strong (this which is the case during a sporting practice).
  • Water repellency is a feature of the textile surface. It corresponds to the fact that under moderate sprinkling (representative of a light rain) the water does not catch on the textile which thus emerges more or less dry.
  • Impermeability to liquid water is a rather mass characteristic of textiles in the sense that water must invade and pass through the porosity of the textile surface. The number and the size of the pores are to be taken into consideration, but also the treatment of the surface of these pores (surface of the woven or knitted fibers).
  • Impermeability is measured by the pressure that must be applied to force water to pass through the fabric. It is customary to speak of a raincoat as soon as the critical water pressure is equivalent to that of a meter of water. In practice, such protection is only useful in 10% of situations (very heavy rain, sustained contact with wet surfaces, etc.). It is instructive to keep in mind that a pressure of the order of 10 cm of water is equivalent to that exerted by a wind of 140 km / h. Bringing all of these functions to a textile material is already in itself a technical feat. In particular, combining water repellency and impermeability with breathability is notoriously difficult. Bringing durable functions to the textile material is an additional technical difficulty. It is known (cf.
  • the present invention therefore aims to provide a treatment which allows to provide lasting functionality to textile materials and in particular functionality suitable for the field of sportswear. Its objective is in particular to provide a treatment which makes it possible to impart a very good breathability and / or a high water repellency and / or a high impermeability to the textile material in a lasting manner, preferably an impermeability corresponding to at least 10 cm of water, better still several tens of centimeters of water.
  • a treatment which makes it possible to impart a durable water repellency and a high impermeability to the textile material (preferably a impermeability corresponding to at least 10 cm of water, better still several tens of centimeters of water), without substantially calling into question the intrinsic breathability properties of the textile material.
  • Another objective of the invention is to provide a treatment which additionally gives the textile, in a sustainable manner, rapid drying capacities and / or reduced water uptake.
  • Yet another object of the invention is to provide a treatment which gives the textile such properties which persist under conditions of wet abrasion and very particularly in the washing.
  • An object of the invention is therefore to provide a method for producing textile materials and articles including them, eg clothing, having durable breathable properties and in particular having a certain resistance to washing and more generally to the constraints of use. .
  • the present invention which relates to the use of at least one crosslinkable liquid silicone formulation as a base for coating a textile material intended preferably for the production of a sportswear : to allow, by crosslinking around the yarns, fibers and / or filaments constituting the textile material, to provide a broad protective cover for the textile material, protection little dependent on the nature of the said material because it requires little or no anchor points; to allow, by making a chemically crosslinking silicone sheath, to ensure lasting protection of the textile material by giving it excellent resistance to the aggressions encountered during use; by the term “durable protection” is meant to define protection on the one hand against the constraints imposed by textile processes such as in particular heat-setting treatments, dyeing treatments, and on the other hand -with respect to aggressions undergone during the life of the textile material (for example a garment) such as in particular abrasion when worn, washing in an aqueous detergent medium, dry cleaning in a solvent medium; to allow, by providing one or more hydrophobicity functionalities
  • the present invention also relates to the use of a crosslinkable liquid silicone formulation comprising one or more hydrophobicity functionalities, for (i) coating a textile material capable of being used in the production of a sports garment and / or yarns, fibers and / or filaments constituting the textile material, the silicone formulation crosslinking around the yarns, fibers and / or filaments constituting the textile material and forming around them a crosslinked silicone sheath, and (ii) lastingly impart water repellency and impermeability to this textile material, preferably without substantially affecting the intrinsic breathability of the textile material.
  • the durability of the above treatment and properties is paramount. Durability can be appreciated in a context including washing the textile material.
  • Tests conducted by the applicant under drastic washing conditions have made it possible to show the remarkable resistance of the silicone treatment, correlated with a persistence of the properties.
  • This durability can be measured by comparing the performance of the treated textile material, before and after having subjected this material to an intensive washing protocol, for example that described in Example 4 (continuous washing with water at 50 ° C., for 8 hours), the material being wrung and dried before undergoing the property testing protocol (s).
  • the beading effect can be measured by the “Spray-Test” method AATC Test Method 22-1996; this method is described in the examples and can consist of a visual evaluation of the wet appearance of the sample: the test consists in spraying the sample of the textile article with a given volume of water; the appearance of the sample is then assessed visually and possibly compared to a standard; a score of 0 to 100% is assigned depending on the amount of water retained; for 0%, the sample is completely wet, for 100%, the sample is completely dry. The sample can also be weighed to measure the weight of water absorbed.
  • the beading effect preferably corresponds to a score of at least 80%, more preferably of at least 90, better still of 100% (range 80-100%>).
  • durability of the beading effect it is meant that, preferably, after the washing treatment, the note remains between 70 and 100%, preferably between 80 and 100%.
  • Impermeability to liquid water can be measured by the Schmerber test (ISO Test Method 811-1981), which consists of applying water pressure to the textile through a water column and measuring the height limit that must be reached for water to pass through the fabric.
  • the targeted waterproofing is preferably greater than or equal to 10 cm of water column according to this test, and so more preferred greater than or equal to 15 cm, better still 20 cm.
  • this impermeability property is meant that, after the washing treatment described, the impermeability is not significantly affected and remains greater than or equal to 10, 15 or 20 cm of water column. Measuring the durability of the water repellency and impermeability properties makes it possible to assess the durability of the silicone treatment according to the invention. The other properties provided by the combination of the textile, these constituent yarns, fibers or filaments, and the silicone treatment also benefit from this durability.
  • intrinsic breathability is meant the breathability of the textile material in the absence of treatment. The present invention makes it possible to produce a textile material having the above-mentioned water repellency and impermeability properties, without substantially calling into question the intrinsic breathability.
  • the treatment makes it possible to limit the uptake of water (weight of water absorbed) of the treated textile and / or to provide it with a rapid drying capacity, and this in a sustainable way.
  • the water uptake of a textile material and its drying speed can be measured by weighing a coupon of this textile material before and after dynamic humidification, and the values obtained expressed as a percentage by weight relative to the weight of the dry coupon. .
  • the low level of water uptake observed makes it possible to limit the “freezing effect”, namely the feeling of cold resulting from heat exchanges in contact with wet clothing.
  • tissue coupons to be tested are subjected to a dynamic humidification phase (placed in a bottle filled with water and subjected to strong stirring for a period of one hour; more precise conditions are indicated in Example 5), then the coupons are weighed (the comparison of the weights before and after humidification provides information on the water intake), put to dry on the scale , in a room conditioned at a temperature of 23 ° C and a relative humidity of 50%, and the change in their weight makes it possible to assess their drying capacity.
  • the values observed will depend on the nature of the textile material.
  • the treatment aims to limit the uptake of water so that the weight of the treated textile material coupon remains at least 50% o, preferably at least 60 or 70% less than the weight of the untreated control coupon.
  • the uses according to the invention preferably aim to provide the textile material in a lasting manner with the three properties of breathability, water repellency and impermeability, preferably associated in addition with a low water recovery capacity. (thus conferring comfort to wear by limiting the heat losses due to the evaporation of water) and rapid drying lasting.
  • the expression "textile material” means: on the one hand, yarns, fibers and / or filaments made of synthetic and / or natural materials which are used for the manufacture of textile articles; and on the other hand the textile articles made from said yarns, fibers and / or filaments, comprising at least one textile surface and consisting for example of woven, non-woven and / or knitted articles, said "made-up textile articles” also encompassing much fabric than clothing, such as jackets and pants.
