Every once in a while we get inquiries from people with wool allergies, or wool sensitivities. The good news is that one leading tzitzit maker in Jerusalem recently introduced a very high quality 100% cotton tallit in a few different designs, including a black-striped cotton tallit and a light blue-striped cotton.
Today we received an inquiry from someone who is so allergic to wool, that even wearing a cotton tallit katan doesn’t solve the problem, rather he needs a cotton tallit katan with cotton tzitzit strings, which is no simple matter.
Lately my allergy to wool has been increasing and I’m at the point I need to stop wearing anything with wool altogether. I understand that tzitzit strings must be wool to be truly kosher, but is any other material available (i.e. cotton, silk, synthetic)? I need to replace all my tallit katan with ones that are 100% non-wool (cotton seems a good choice) including the strings. Please let me know your thoughts on this and if you have such options for such cases. Thank you, Robert
I explained to Robert that according to halacha you can put wool or linen tzitzit on any type of garment. Linen is almost never an option because of shaatnez issues.
