Many people often look for Talit at low prices and they come across non-Halakha compliant Talit according to most makers.

Our Hakhamim tell us that a garment made of leather is not considered a garment, strictly speaking, because it is a material that cannot be woven.

As for synthetic materials such as viscose or other, there is a difference with leather. Indeed, it is possible from synthetic yarns to produce a weave and thus create a garment. There are therefore divided opinions as to whether this matter is subject to the ordinance of Tzitzit. Nowadays, the majority of decision makers believe that one cannot fulfill the Mitzvah of Tzitzit by donning a garment made of synthetic material.

However, if one wears a garment with four corners made of synthetic material, one will have to tie Tzitzit on this garment since there remains a doubt but one cannot rely on this to fulfill the Mitzvah of Tzitzit and to make the blessing on it. (Or Leztion)

  Tsitz Eliezer explains that the garment will not be exempt from Tzitzit but he cannot make a blessing.

Everything we have said from the beginning concerns a Talit Katane or a Talit Gadol.

Thus, since there are doubts and disputes about the material of the Talit Katan, when we recite the blessing in the morning on the Tallit Gadol made of wool, we will think of also paying for the Tallit Katan that the we carry the day.

The only material for which we have no doubts is wool or linen. Linen these days is not possible since tzitzit are made of wool.

Pay attention to purchases

  When buying a Tallit Gadol, it will be necessary to check that it is made of wool because if it is synthetic, there will be no fulfillment of the mitzvah and one will not be able to recite a blessing given the doubt that subsists.

So very problematic the synthetic. Cotton however will also be possible according to the Ashkenazi custom to make the berakha on it.
