What does this sentence mean?

"It has also served to isolate polyester staple prices
from the upward price pressure that the fluctuations
downstream in raw materials have justified."

I think somthing influenced the price of polyester staple did not go up.
But I can't figure out "...that the fluctuations downstream in
raw materials have justified."
what that mean?

More context might be helpful here. The phrase "fluctuations

That helps a little. (I can see now that it's a metaphor.) What about the "fluctuations" part and the "justify" part?

I presume that raw materialprices have risen, but polyester staples are not affected by the upward pressure.
