Will it damage a wool jacket to wash it in cold water on the gentle cycle and let it air dry?

It's only 48 percent wool and the rest is a nylon polyester blend.Will it damage a wool jacket to wash it in cold water on the gentle cycle and let it air dry?
If you can read the label, see what it says. If it says dry clean only, do that. Why do you want to clean it? Does it smell or is it dirty? That will help decide what to do. If is just smells, try hanging outside for a couple of hours. If it is visibly dirty, you can wash it in cold water on gentle and let air dry, not in the dryer, but it may shrink a bit. Dry cleaning will get it clean but won't do much for smell. With the blend, I personally would try washing it myself unless the tag told me not to. Sometimes it's because of the dyes they use they say to dry clean only. If it zips, washing may make the zipper bulge and not work properly. Wash at your own risk if it says dry clean only.


Hope this helps you make a decision.Will it damage a wool jacket to wash it in cold water on the gentle cycle and let it air dry?
As you said.Its a mixture of polyester and wool.As The wool content is less, you can wash in cold water but without spin dry.If it's 100%wool you can't wash in water.
If you use a detergent specifically for use with that blend of fabrics(like woolite) there will not be a problem , just don't put it in a dryer or it will shrink! Air drying is the best for it if it's laid out on a drying rack made for that purpose.
It may shrink a little.
