I would try after the shirt is sprayed with pretreat, to brush down the fibers with a brush, I myself use a china bristle brush, brush them only down, in one direction, and then dry in the press. This will sometimes happen if the shirt has very loose fibers. What brand of shirt are you using. Also when you cure, cure with the lightest of pressure you can. The more pressure you use, the more the fibers will be pressed up through the ink. But brushing down the fibers after spraying the pretreat really works good. Here is a thread that has alot of great pretreatment info and tips
Little Fibers Sticking Up Off Shirt any fix?. Hope this helps some, let us know.
