Keilim 28:8-9

Keilim 28:8

The clothes of needy people are susceptible to midras impurity even if they’re not three fingerbreadths by three fingerbreadths. If a cloak began to rip, once the greater part of it is torn, the pieces are no longer considered connected. The rule of three fingerbreadths doesn’t apply to thick or delicate materials (i.e., these must be three handbreadths by three handbreadths in order to be susceptible to impurity).

Keilim 28:9

A porter’s cushion is susceptible to midras impurity. A wine filter is insusceptible to impurity as a seat. An elderly woman’s hairnet is susceptible to impurity as a seat. A prostitute’s net-like shirt is insusceptible to impurity. If one makes a garment from a fishing net, it is insusceptible to impurity but one made from the bag of a fish net is susceptible. Rabbi Eliezer ben Yaakov says that if a garment made from a fishing net is doubled over, then it’s susceptible to impurity.
