Use of a sulfonated reagent in a process for producing a white polyamide article, comprising at least the following steps: a. polymerization of at least one monomer to obtain a polyamide in the form of a melt, granule or powder, b. formation of the polyamide article from the melt polyamide, granule or powder, c. Optionally, conversion of the polyamide article using a texturing process, the sulfonated reagent is introduced during step a. and / or stage b. and / or step c., in order to provide resistance to phenolic yellowing to the white polyamide article obtained when in contact with plastic packaging material containing phenolic compounds. |
