Order of Priority of Materials for Garment and Which Material for Tzitzit

p. 31 Chapter Ten   Al HaShulchan

1. A Tallit made of goats' wool or camels' wool is in the same category as a tallit made of cotton about which there is a difference of opinion if the obligation to affix zizit thereon is a Torah one or of Rabbinical institution.  One can insert on them either ziziot of the same material or else of sheeps' wool.  It is preferable to buy only a tallit made from sheeps' wool which according to all opinions has a Torah obligation (to have ziziot).  If that is not available one should buy a cotton tallit which is on a lower level of obligation, or a silk one, in which case one should check that the ziziot are made from sheeps' wool.  A tallit made of a mixture of materials, for example: the warp (lengthwise) is wool and the weft (breadth) is cotton, is on an even lower level of obligation, and requires also only sheeps' wool zizit. (Ben Ish Chai Noach 1,2)

We would like to dedicate this learning for the speedy and complete recovery of two people: our friends' 5-year-old son, Joseph Benjamin, son of Ireneusz Khrystof, diagnosed in April with ALL leukemia, and a longtime friend of the family, Frank, son of Joseph, having thyroid surgery soon. Please have them in mind when studying. If you would like updates on their progress, please let me know so I can tell you when I find out from either or both.
