קורקורקתה (lower border of a web) – the hem and the bottom, like the rimmed bottom of the vessels.

Introduction Our mishnah deals with the susceptibility to impurity of a hair-net.

עד שיגמור את פיה (until he completes its hem) – its upper rim/hem, that does not descend into defilement until he completes all of its work.

A hair-net that one began to make from its upper hem remains pure until its bottom section is finished. If one began from its bottom section, it remains pure until its hem is finished. When making a hair-net, it is not considered completed until both the top hem and bottom hem are finished, and it doesn't matter whether one begins to sew from top to bottom or bottom to top.

שביס שלה (the band of the net) – from the language of “the bands and the enclosed places.” It is a painting that one makes on the hairnet for beauty. It stands on her forehead and surrounds it from eat to ear. And it is also considered on its own, that it is made to remove it from there, and to place it in another hairnet.

Its head band is susceptible to uncleanness in itself. The head band is considered a vessel independent of the rest of the hair-net and therefore is susceptible even if separate. Furthermore, it is not considered connected to the head band and if it is impure, the hair-net can still be pure.

טמאים משום חיבור – that if the hairnet is defiled, all the stings are defiled with it. For it were strings/threads without the hairnet, it would not be susceptible to receive ritual defilement.

Its strings are susceptible to uncleanness because they are connected. The strings which come out of the hair-net are considered connected, because they cannot be removed. Therefore, if the hair-net is impure, the strings are impure as well.

A hair-net that is torn becomes pure if it cannot contain the greater part of the hair. Once the hair-net is torn enough such that it cannot contain the greater part of the hair, it is no longer functional and it is not susceptible to impurity.

אם אינה מקבלת את רוב השער – of the head, it is pure/clean.
