Up to 40 textile workers have lost their jobs with the closure of an apparel factory in the traditional US textile heartland on North Carolina.

Around three dozen employees of Swag-Nit Inc left the Salisbury plant for the last time on Friday although around 10 have been taken on by Roman Knit Inc which bought Swag-Knit's machinery.

The firm, which has a clothing joint venture in Mexico, will continue to operate from its headquarters in Mount Holly.
