DuPont said the cuts represent about 10% of DTI's work force. More than two-thirds of the job cuts will occur in the United States, where DTI will close a manufacturing unit in Niagara Falls, N.Y. and parts of its spandex facility in Waynesboro, Va.
Since April 2001, DuPont has cut 5,500 jobs, or 6% of its work force.
Last year, DuPont cut 2,000 jobs from its nylon and polyester fibers business, shutting down some manufacturing lines. Nylon sales fell 14% last year. Polyester sales decreased 17%.
DuPont expects to realize annual pre-tax cost savings of about $120 million and plans call for more than half of the affected employees to leave the company by July 31.
