Fleece HELP! Fleece not wicking after tons of washes!

So a few days ago, I went to the nearby Fabricland, much like Joan's, but the Canadian version, and bought three large pieces of antipill fleece, currently, I have three older pieces that wick, that I bought at the beginning of my piggies ownership. TOMORROW, I am going on a trip to Europe, and the girls are staying at a pet resort. They are in need of as many changes of fleece as possible, so I want to bring six with me. I have soaked the fleece in the tub with vinegar, and washed it more times than I can think. Since I'm on the younger side of the ages on the forum, I live at home with my parents, and we just spent 30$ on three pieces of fleece, not sure if this is exspensive, but to one with a limited income, it seems to be, especially with the added cost of washing it like, ten times.

I use an eco friendly, unscented, no fabric softener, detergent, along with lots of vinegar. I did the same thing last time, and the wicked within three washes. Not this time! I have three pieces of the mountain antipill fleece, and I appears to be a bit thicker than my other pieces. Help! I need this to work within the next 12 hours!

Any advise would be wonderful!
