Query: JOCKEY UNDERWEAR CHEMICAL SMELL

I've used Jockey men's underwear for many years and I have favored the Elance bikini design as the most comfortable, but the last few times I've bought them they have had a terrible acrid chemical smell which is very difficult to wash out. I've now seen other buyers' complaints about the same problem. I've twice emailed the Jockey International Corporation in Kenosha, Wisconsin, about the problem, but have received no response.
