Bamboo Fabric?

I have a bathroom rug made of bamboo fabric. It is very soft and very attractive. The directions say to handwash it. I am not about to handwash a rug, so the first time I washed it, I put it in the machine and hung it to dry. A tiny section on the edge did came unraveled, so I think next time I wash it I will put it in a mesh bag. It's very nice, and as I said, so soft when you walk on it barefoot. I've had it less than a year, but I'm guessing it will last quite awhile.
