All garments can contract the uncleanness of negaim except those of non-Jews. One who buys garments [with signs of negaim] from non-Jews they must be inspected as if the signs had then first appeared. The hides [of animals] of the sea do not contract the uncleanness of negaim. If one joined to them anything which grows on land, even if it is only a thread or a cord, as long as it is something that is susceptible to uncleanness, they also become susceptible to uncleanness.

Camel's wool and sheep's wool that have been hackled together: If the majority is camel's hair, they are not susceptible to negaim; But if the majority is sheep's wool they are susceptible to negaim. If it is half and half they are susceptible to negaim. And the same law applies also to linen and hemp that have been hackled together.

Colored hides and garments are not susceptible to negaim. Houses whether they are colored or not colored, are susceptible to negaim, the words of Rabbi Meir. Rabbi Judah says: hides are like houses. Rabbi Shimon says: those that are naturally [colored] are susceptible to uncleanness but those that are artificially [dyed] are not susceptible to uncleanness.

A garment whose warp was colored and whose woof was white, or whose woof was colored and whose warp was white, all depends on what is most visible. Garments contract uncleanness if they are an intense green or an intense red. If [the nega] was green and it spread out red, or if it was red and it spread out green, it is unclean. If its color changed and then it spread, or if it changed and it did not spread, it is regarded as if it had not changed. Rabbi Judah says: let it be inspected as if it then appeared for the first time.

[A nega] that remained unchanged during the first week must be washed and isolated. One that remains unchanged during the second week must be burned. One that spread during the first or the second week must be burned. If it becomes dimmer in the beginning: Rabbi Ishmael says: it should be washed and isolated. But the sages say: he is not required [to do so]. If the nega became dimmer during the first week it must be washed and isolated. If it became dimmer during the second week it must be torn out, and that which is torn out must be burnt, and it is necessary for a patch to be put on. Rabbi Nehemiah says: a patch is not necessary.

A screen that had colored and white stripes, a nega may effectively spread from one to the other. They asked Rabbi Eliezer: But the white stripe is separate? He replied: I have heard no ruling on this question. Rabbi Judah ben Batera said to him: Shall I derive the answer? He replied: If this would confirm the words of the sages, then yes! He said back: It is possible that it would remain on it in an unchanged condition for two weeks, and that which remains unchanged on garments for two weeks is unclean. He said to him: You are a great sage, for you have confirmed the words of the sages. A spreading that is close [to the original nega is effective] however small it may be. One that is distant [is effective only] if it is of the size of a split bean. And one that reappears [is effective only if it is] of the size of a split bean.

The warp and the woof can contract the uncleanness of negaim immediately. Rabbi Judah says: the warp, only after it has been boiled, but the woof immediately. And bundles of flax after they have been bleached. How much must there be in a coil for it to be capable of contracting the uncleanness of negaim? Enough to weave from it a piece of three fingerbreadths square, either warp or woof, even if it is all warp or all woof. If it consisted of broken threads it does not contract the uncleanness of negaim. Rabbi Judah says: even if the thread was broken only in one place, and he knotted together, it does not contract the uncleanness of negaim.

One who winds [a thread] from one coil to another, or from one spool to another, or from the upper beam to the lower beam, and so also in the case of the two sides of a shirt, if a nega appears on the one, the other remains clean. If it appears on the shedded woof or on the standing warp, they become susceptible to the uncleanness of negaim immediately. Rabbi Shimon says: the warp may contract uncleanness only if it is closely ordered.

[If a nega] appeared on the standing warp, the already woven cloth remains clean. If it appeared on the already woven cloth, the standing warp remains clean. If it appeared on a sheet, he must also burn the fringes. If it appeared on the fringes the sheet remains clean. A shirt on which a nega appeared affords protection to its hems, even though they are of purple wool.

Any object that is susceptible to corpse uncleanness, though not susceptible to midras uncleanness, is still susceptible to negaim uncleanness. For instance: the sail of a ship, a curtain, the forehead band of a hair-net, the wrappings of scrolls, a coiled belt, the straps of a shoe or sandal that are at least as wide as a split bean, Behold these are susceptible to the uncleanness of negaim. A thick cloak on which a nega appeared: Rabbi Eliezer ben Jacob says: unless it appears on the texture and on the stuffing. A skin bottle or a shepherd's leather wallet are inspected in the position in which they are used, and a nega may effectively spread from its inner side to its outer side and from its outer side to its inner side.

If a garment that had been isolated was mixed up with others, all are clean. If it was cut up and made into shreds, it is clean, and benefit may be derived from it. But if a garment that had been certified unclean was mixed up with others, all are unclean. If it was cut up and made into shreds it also remains unclean and it is forbidden to have any benefit from it.
