Cash-strapped apparel manufacturer and retailer, Warnaco Inc, is to sell its former sewing factory and distribution centre in Costa Rica as it looks to raise cash to help it emerge from bankruptcy protection. The company said it was inviting offers for the 38,000sqft facility near San Jose and is also selling off 65 acres of vacant land in Duncansville, Pennsylvania, and a 234,000 square foot distribution and manufacturing facility in Murfreesboro, Tennessee.
