Sweat from ritual impurity usually doesn’t make a garment impure — but if any actual najasah (like semen) touches the fabric, washing becomes obligatory.

Is Your Shirt 'Impure'? The Simple Rule Everyone Gets Wrong

If a garment worn by someone who is junub has only been affected by sweat and not by another impurity, washing it is not obligatory. For greater caution, however, one may wash it.

Necessity of washing a person’s clothes after junub: a comprehensive review

Your question about whether a garment worn by a person in a state of junub must be washed is an important issue within the rules of ritual purity. In general, a junub person’s clothing does not automatically become najis, and washing it is not required.

For a more precise answer, several points should be considered:

Sweat from junub: Sweat produced during a state of junub, if it is only sweat, is not considered najis. Nevertheless, the precautionary ruling is that one should not perform prayer (salat) with a body or clothing soiled by such sweat without ensuring purity.

Contamination of the garment: If the clothing of a junub person is contaminated with semen or any other impure substance, the affected part of the garment becomes najis and must be washed.

Precautionary practice: In some cases, religious scholars recommend adopting precaution and washing the clothing even if it does not appear to be visibly contaminated.
