Leading knitwear manufacturer Delta Apparel Inc on Tuesday posted a small rise in first quarter net profit to $1.8 million from $1.7m in the year-ago period despite sluggish sales. The Georgia-based firm, which specialises in undecorated T-shirts, golf shirts and tank tops and employs around 3,100 people worldwide, said sales fell 6.9 per cent to $28.9m from $31m in 2001.
