ATLANTA—After nearly 100 years in business, Trio Manufacturing Co., a Forsyth, Ga.-based manufacturer of cotton sales yarn, is closing down all of its textile manufacturing operations.

The family-owned company, established in 1899, said it expects closure by the end of this year. It currently employs about 20 associates.

Howell W. Newton, president, said the company had significantly downsized its operation in January with the hope of keeping enough market share to cut losses. He said that “customers had continued to move their production out of this country or just go out of business.” Conditions began to seriously deteriorate around the first of September.

Trio will honor all financial obligations and provide severance for all associates, Newton said.
