Denim producer Cone Mills will lay off a further 190 employees later this month after announcing plans to close the ring spinning and winding department at its White Oak plant.

The North Carolina-based manufacturer, which in October said it would axe 625 jobs with the closure of its Cliffside Finishing and Haynes plants, has blamed this latest measure on the continuing flood of low-cost textile imports to the US.

"This is always a difficult and awkward thing to encounter," vice-president of human resources Terry Weatherford said.

"However, this is part of the company's reconfiguration that has been well publicised in the past few weeks.

"This was necessary to make our plant competitive and keep it viable so it can compete against foreign producers."

Cone Mills is the world's largest denim maker and a fabric supplier to Levi Strauss.
