DuPont reports that sales and earnings have declined in the 1st quarter, with sales dipping 10 percent to $6.14 billion and net income declining 3.2 percent to $479 million. The company pointed to a continuing weakness in the U.S. textile market as the reason for significant declines in fiber prices and volumes. Spandex was a lone textile glimmer in an otherwise dim report, posting volume gains, but as a result of lower pricing. DuPont officials stated in its report that it fully expect second quarter earnings to rise, perhaps as high as a double-digit increase over last year.
