Melacha #14 – Menapeitz (Combing)
After shearing the wool off of the sheep and scrubbing it clean, the wool had to be combed to untangle it. This is the melacha of menapeitz.
Menapeitz applies to any material that can be processed into a textile-like form, whether it’s wool, cotton, polyester or even straw. However, it only applies to hair or fur that is detached from a living creature. (Combing a living creature is forbidden under the melacha of gozeiz – shearing – due to the likelihood that some hair or fur will be pulled out as a result.)
Combing the fur collar of a coat is forbidden due to menapeitz. According to some authorities, combing a sheitel or a wig on Shabbos is problematic because of menapeitz.
This is just an introduction to the concepts of the melacha of menapeitz; it is not a substitute for a full study of the halachos.
