clothing - Esrog flax on woolen clothes


I haven't seen it in a few years, but esrogim used to come wrapped in flax. Or, at least, a yellowish, brownish, hairy substance people called "flax", which leads us to my first question:




This stuff would get everywhere. In particular, it would get on one's clothes, which leads us to my main question:



  • If it was really flax, and it got on one's woolen clothes, was that a problem of shaatnez?



Answer



According to Shabbos 54a, this would not meet the requirements for shaatnez.


A double-fastening is needed to make flax and wool into a Kli.


One stitch holding a piece piece of wool to a piece of linen is not liable, two stitches are needed. Also, if you wrap a cord of wool and a cord of flax around your hand, you're are liable (eg. leading two camels, one with a wool leash and one with flax). Even though it is not held together with two stitches, you may knot the two cords together, and that would make you liable (even unintentionally).
