Different types of fabrics can be washed together, but it is always best to check the care labels before doing so. If one item of clothing has a ‘dry clean only’ label, then it is best not to wash it with other items. Different fabrics also have different washing temperatures, so it is important to check that all items can be washed at the same temperature. Mixing different types of fabric can also affect how long they take to dry, so it is worth considering this before putting a load in the tumble dryer. In general, it is best to err on the side of caution and wash similar fabrics together.
