Similarly to the cosmetic properties, a special “Task Group” has been created, which will start its activities in 2022. ITSAPT 35 Luis Almeida Chemical analysis of textiles Especially in view of detection of harmful substances, it is very important to have standard methods for extraction of chemicals from textiles. Aspects to be standardised include sampling and extraction methods. ITSAPT 36 Luis Almeida Chemical analysis of textiles Two important standards have been developed within CEN/TC248 in 2022, related to the EU Directive that forbids the use of certain azo dyestuffs: EN 14362 Textiles Methods for the determination of certain aromatic amines derived from azo colorants Part 1: Detection of the use of certain azo colorants accessible without extraction Part 2: Detection of the use of certain azo colorants accessible by extracting the fibres. ITSAPT 37 Luis Almeida Chemical analysis of textiles The method of sampling has not been adequately thought out, with the result that some laboratories base results on the whole garment and others on the area containing the harmful chemical. The sampling method should be defined so that all users will use the same criteria and results from different sources will be parable. ITSAPT 38 Luis Almeida Chemical analysis of textiles In terms of extraction of chemicals from textiles, there are different possible approaches. For instance, 214。koTex 100 Standard limits are based on an extraction with an anic solvent, a simulated sweat or saliva solution. The analysis of the extracts is mon to most existing test methods. ITSAPT 39 Luis Almeida Chemical analysis of textiles The following decisions have been taken: a) within CEN/TC248/WG9, Irene H228。glund (IFP) will make in 2022 a survey in the area of chemical analysis of textiles. b) within CEN/TC248, a new working group WG26 has been created, under the convenorship of Stefan Posner (IFP), to develop a Method of Test for Phthalates. ITSAPT 40 Luis Almeida CONCLUSION The development of new functionalities in textiles leads to the need of standardisation in terms of Terms and definitions Test methods Labelling… ITSAPT 41 Luis Almeida CONCLUSION Within textiles, CEN/TC248/WG9 will continue to promote these developments. Hopefully, the 7th EU Ramp。D Framework Programme will devote a specific budget for actions related to pre and conormative research.
