Why are polyester suits dry clean only?

Why are polyester suits dry clean only? Other types of polyester clothes can be washed in the washing machine, why is it advised not to wash polyester suits in the washing machine though?

I understand that 100% wool cannot be washed in the machine but I don’t get how 100% polyester or something like a 80/20 poly-wool mix couldn’t be washed in the machine.

And we don’t want a discussion about how polyester sucks in this thread. We all know that it is bad compared to wool and other natural materials but that is not the point of this thread.

      What if you use the delicate cycle on the washer and maybe also put the garment in a garment bag that protects it? How will the lining be wrecked?

          Pilling is just a property of fabric, its shorter fibers coming loose, its most extreme in woolen fabrics (specifically woolen, worsted wool doesnt pill much) but it can happen in cotton synthetic etc

          it will pill and fuzz, just more slowly than other fabrics suits are made of.
          scratchier hand feel polyester tends to actually get a lot nicer after its first wash, then slowly degrades from consecutive washes.

          It’s polyester it should be fine

          Honestly they probably said dry clean only to make it seem on par with a real suit

          a lot of polyester jackets use rayon or other material liners which shrink like a motherhecker.

          I washed a wool sport coat following the gentleman’s gazette guide. Low temperature, wrapped tightly in a towel. It still came out around one inch smaller horizontally and vertically. Sure, polyester should not shrink that much, but who knows

          ive had hand washing gently in a bucket and throwing shit on cold/no spin go well and ive had it be a disaster.
          use an unscented liquid soap instead of detergent i use the unscented dr bronners.
          always hang dry, don’t hang heavier garments by their shoulders ever.
          it depends not only on the exact synthetic composition but how its woven, fiber size etc too so there’s no reliable way to know.

    I used to wear a cheap polyester suit for a job I did, and I would just wash the jacket as if it was a normal garment. The only problems were pilling + lost some of the sleeve buttons.
