Yarn giant Unifi Inc on Wednesday reported a narrower second quarter net loss of $2.2 million versus $3.5m in the year-ago period but said sales during the period slipped 5.5 per cent year-on-year to $201.9m. The North Carolina-based firm, one of the world's largest producers and processors of textured yarns, said in a statement it attributed the sales slip to reduced sales prices accompanied by a change in product mix.
