All garments become tamei from negaim, ex-cept those of gentiles. Clothing purchased from a gentile should be examined initially. Skins of sea [creatures] do not become tamei with negaim. [If] one attached something that grows on land to [the sea skin], even a thread or a string, anything that is generally susceptible to tumah, it is tamei.

Camel’s wool and sheep’s wool that were mixed together: If the majority is from camels, they do not become tamei from negaim; if the majority is from sheep, they become tamei from negaim; [if the wool is mixed] half and half, they become tamei with negaim. The same applies to linen and hemp that were mixed together.
