- the moisture uptake of the compositions is measured by variation in weight after a residence time of 48 hours in an enclosure conditioned at a relative humidity of 94% at 30 ° C or 54% at 30 ° C, then a passage of 16h in oven regulated at 80 ° C under a pressure of 7 mm of mercury.
- the moisture uptake is calculated as follows:
- the adhesion of the additives to the matrix is determined by variation in weight before and after washing.
- the washing operation simulates the treatments that the product may have undergone: dyeing, washing. 4g of composition are ground at cryogenic temperature with a grinder
- RETSCH ® Ultra-centrifugal ZM 1000 fitted with a 1 mm grid.
- the powders are then dried at 80 ° C for 48 hours and weighed.
- a 10% solution in demineralized water (4 g of powder for 36 g of water) is prepared.
- the solution is then kept under magnetic stirring at 500 rpm for 30 minutes at room temperature.
- the solution is then filtered through filter No. 11 (Prolabo®), the filtrate and the cake are dried at 80 ° C for 48 hours and weighed.
- Weight loss (release) is then calculated:
- Polyamide A2 Polyamide 66 not comprising titanium dioxide, with a relative viscosity of 41 (measured at 8.4% of polymer in 90% formic acid).
- Polyamide A3 Polyamide 66 comprising 1.6% by weight of titanium dioxide, with a relative viscosity of 41 (measured at 8.4% of polymer in 90% formic acid).
- Polyamide A4 Polyamide 6 comprising less than 0.03% by weight of titanium dioxide, with a relative viscosity of 2.06 (measured at 1% of polymer in 90% sulfuric acid).
- Additive B2 hydrophilic star polyamide of Example 3
- Yarns comprising the polyamide and one of the additives are prepared by mixing in a single-screw spinning extruder with supply of granules of each of the constituents, melt spinning at a temperature of 285 ° C. or 260 ° C respectively for polyamide 66 and polyamide 6.
- the wire is wound at a speed of 4200 m / min and at different rates.
- the compositions thus produced are given in Table 4.
- the moisture uptake of the compositions is measured in the same way as in Examples 4 to 6, at a relative humidity of 94% at 30 ° C., on powders prepared as follows: 4 g of composition are ground at cryogenic temperature with a RETSCH® Ultra-centrifugal ZM 1000 mill equipped with a 1 mm grid. The powders are then dried at 80 ° C for 48 hours and weighed. The results are presented in Table 5
- the adhesion of the additives to the matrix is determined in the same way as in Examples 4 to 6.
- the salting out (% by weight) of the compositions of Examples 7 to 12 is less than 6, that of the compositions of Examples 13 to 17 is less than 0.3.
- A5 polyethylene terephthalate (reference MTV1160)
- A6 polybutylene terephthalate
- A7 polypropylene (Profax® reference 6301)
- Granules comprising the polymer and one of the additives are prepared by extrusion in a twin screw extruder with supply of granules of each of the constituents.
- the compositions thus produced are given in Table 6.
- the moisture uptake of the compositions and the adhesion of the additives to the matrix are determined on powder, in the same way as in Examples 7 to 17. The results are also presented in table 6. Table 6
