- the tenacity of the "regular" yarns are 4%, 13%, 15%, 15.5%, 19% higher than those of the "lighter" yarns for the respective batches 1, 2, 3, 4 and 5.
- the elongations of the "regular" yarns are 11%, 10.5%, 14.5%, 26% and 33% respectively higher than those of the "lighter" yarns for the batches 1, 2, 3, 4 and 5.
- Example 2 Influence of the pretreatment according to the invention on the mechanical properties and the dye affinity. No pretreatment:
- a batch of polyamide yarn PA6-6, 44 decitex, consisting of 48 filaments is considered. This yarn was knitted with 3-filament spandex yarn to make a knit fabric containing 20% elastane (batch 6).
- This batch was the subject of a customer feedback following dyeing defects found with an acid dye of dark purple color with which it is particularly problematic to obtain a sustained and uniform dyeing on polyamide knits subjected to heat treatment.
- the customer return concerns part of lot 6 having undergone the following operations:
- the knit is passed through a padding bath containing only water and is then spun between two squeeze rolls.
- the knit is then dyed with the dye on a JET device.
- the spacing of the squeezing rollers at the outlet of the padding tank has been adjusted so that the load-bearing rate of the knitting material is of the order of 60%, which represents a deposition of active material (excluding water) of the 3.5 g / 100 g of dry knit.
- the sample thus treated is of industrial size. It represents approximately 500 kg of treated thread. The entire sample showed a uniform appearance and a color with the required intensity after dyeing (regular).
- compositions according to the invention make it possible to preserve the dye affinity of the fibers and to improve the unison of dyeing.
- Downstream treatment with a composition according to the invention :
- This last knit (lot 7) is made with a polyamide yarn from the same reel as that of lot 6, but it has, contrary to that of lot 6, previously undergone a heat treatment at the time of shaping ( texturing).
- the result after dyeing is a knit of a shade much too light, despite the treatment with the composition according to the invention, applied before the dimensional stabilization heat treatment but after heating during texturing.
- compositions according to the invention therefore do not make it possible to restore the mechanical properties and the dye affinity of polyamide fibers already heat-treated.
- a treatment with these compositions must be applied in the form of pretreatment upstream of the heat treatment.
- Example 2 The pretreatment of Example 2 was reproduced with a composition C2 according to the invention containing:
