This brief article contains links to the two extensive articles on wet finishing. Wet finishing is an important process in creating woven cloth. When the cloth comes off the loom what you have is a net of yarn. The process of wet finishing converts the net into cloth. The yarn relaxes, the weave pulls together, and when dry the result is woven cloth. All weaves using any yarn fiber should be wet finished. Some will say that acrylic does not need to be wet finished. Acrylic will relax and the weave will come together just as a weave of any other fiber. There is a definite positive difference before and after wet finishing.
