Definitions
- the present invention relates to a textile material, such as a yarn, a fiber, a filament (monofilament or multifilament), a membrane, a porous membrane, a woven or non-woven fabric, comprising at least one synthetic fiber made of thermoplastic elastomer polymer. .
- Texttile or “textile” means any material made from fibers or filaments and any material forming a porous membrane characterized by a length / thickness ratio of not less than 300;
- Fiber means any synthetic or natural material characterized by a length / diameter ratio of not less than 300;
- filament means any fiber of infinite length
- Textiles include fiber mats (dressings, filters, felt), wicks (dressings), threads (sewing, knitting, weaving), nonwovens, web veils "Nets, (net), knits (straight, circular, fullyfashioned) fabrics (traditional, jacquard, multiple, double sided, multi axial, 2D and a half, 3D), and many others.
- textile materials that are both flexible, stretchable, solid, that is to say, resistant to tearing, and anti-pilling, that is to say, resistant to abrasion.
- the object of the present invention is to improve the flexibility, the stretchability, the strength of these textile materials and their resistance to abrasion.
- Flexibility is evaluated using the modules: tensile modulus according to ISO 527 1A: 2012, and flexural modulus at 23 ° C according to ISO 178: 2010. A decrease in these modules is in the direction of greater flexibility of textile materials.
- the stretchability is evaluated using the elongational rheology test, as defined hereinafter in the examples of the present application.
- the anti-pilling property is measured by the abrasion resistance which is evaluated by the mass loss according to ISO 527-1A: 2012: the lower the mass loss of the material, the better the abrasion resistance textiles based on this material. Tear resistance is evaluated according to ISO 34-1: 2015.
- PEBA polyamide block and polyether block copolymers
- These PEBAs belong to the particular class of polyetheresteramides when they result from the copolycondensation of polyamide sequences with reactive carboxyl ends with polyether sequences with reactive ends, which are polyether polyols (polyetherdiols), the bonds between the polyamide blocks and the polyether flexible blocks. being ester bonds.
- PEBAs are known for their physical properties such as their flexibility, their impact strength, and their ease of implementation by injection.
- these copolymers are difficult to process as textile material by extrusion, in particular because of a low melt viscosity and a low melt strength resulting therefrom.
- melt viscosity by lengthening the polymer chains, for example by prolonging the polymerization.
- This approach has been disappointing due to the degradation of the blocks, which also leads to a coloration (yellowing) of the material, without being able to reach the desired levels of melt viscosity, of at least 300 Pa.s, measured according to ISO 1621-10: 2015.

- Table 1 gives the melt viscosity measurement results eta * (in Pa.s) at 220 ° C., as a function of the angular frequency (rad / s) according to the standard ISO 6721-10: 2015. Table 1
- Copos materials according to the invention have a higher melt viscosity than the comparative PEBAs.
- Copos materials according to the invention are therefore more easily extrudable in textiles than comparative PEBA materials.
- a rod is extruded through a die of a capillary rheometer; it is entered in the molten state by two pairs of wheels driven by a variable speed motor.
- a first pair of wheels and the motor are mounted at the free end, deviable, a support connected directly to a sensor, representing the restoring force.
- the second pair of wheels (coupled to the first pair) makes it possible to guide and limit the winding of the ring around the upper wheels.
- Small buffers soaked with surfactant liquid water, ethanol, and surfactant mixture) are also applied to the wheels to cool them and thus limit the bonding effect.
- the strenqht melt curves of FIGS. 1 and 2 represent the elongation constraint on the ordinate as a function of the elongation factor on the abscissa.
- Test temperatures 150 ° C or 180 ° C depending on grades

- the textile materials based on the copolymers according to the invention have a better tear resistance than the textile materials based on the respective control PEBAs.
- the average molecular weights by weight and by the number Mw and Mn measured increase respectively when passing from a PEBA to the corresponding Copo according to the invention, which indicates that the reaction has taken place between the carbodiimide function of the polycarbodiimide and the function PEBA acid to form the end-blocked acid end Copo used according to the invention.
- the dispersity is determined to be equal to the ratio between molecular weight and number Mw / Mn. The accuracy of the measurement is given to within 5%.
- the number average molecular (or molar) mass is set by the chain limiter content. It can be calculated according to the relation:
- niimiter number of moles of excess diacid
- Repeat pattern Molecular weight of the pattern of repetition
- Miimiteur Molar mass of excess diacid
- the Mw / Mn dispersity is also preserved in each Copo according to the invention with respect to the corresponding initial PEBA, and it is measured less than 3, in all the copolymers, which proves that the copolymers according to the invention remained in the form of linear non-crosslinked.
- the textile materials based on these copolymers therefore remain perfectly recyclable.
- the polycarbodiimide thus used in the textile material according to the present invention makes it possible to improve the properties of: extrudability, stretchability, flexibility, abrasion resistance, and tear resistance of the textile material, while maintaining its recyclability.
