Dear Thiru Thiru ,

find a suitable solvent. I think formic acid is the best candidate to solubilize nylon6 (though ignoring the other phase nature of the composite). Regards

Thanks for your reply BOUAZI. But formic acid will dissolve all....Tell me any other method to seperate

Dear

If you want to design a recycling line it's better to focus on grinding and separation by difference of density method such as floating or air blowing method.

If you do lab scale project you can use solvent like m-cresol, formic acid and …. To solve PA

Dear Shervin Ahmadi Can you share any experimental work or publication ?

Dear

It will be my pleasure but please send detail of your work and information such as  the type of fiber, the quantity of recycling material, if they use any filler in matrix please clarify that

Regards

Dear Thiru,

From my personal experience with natural fiber reinforced polyamide-6 composites, I can confirm the suggestion of the collegue of using formic acid. The use of a Shoxlet extractor or even the direct solubilization of the matrix is an effective way to separate the PA-6 from the fiber. Nevertheless, bear in min that it will highly depend on the characteristic of your reinforcement. I hope this may help you somehow.

For dissolution of PA6 formic acid will be the solvent of choice as suggested by Abdelkader. In case this does not fit with your requirements, you can also try boiling glacial acetic acid, DMF and DMSO, resp.

Dear Thiru, you can find that I used formic acid in this work: https://www.researchgate.net/publication/229146225_One-step_functionalization_and_reactive_blending_of_polyolefinpolyamide_mixtures_%28EPMPA6%29

However I think also trifluoroacetic acid can work. Regards

thank you to all. i am trying as per all your suggestions. i will ask all  your suggestion once again when that idea is not working... thanks once again

Dear all;

would you please specify the other phase nature for further suggestions. Regards
